Automobile water tank vent

Automobile water tank, also known as radiator, is the key component of automobile cooling system. The function is to dissipate heat. The cooling water absorbs the heat in the water jacket, flows to the radiator, radiates the heat, and then returns to the water jacket to adjust the temperature. It is a structural component of an automobile engine. Then, Bian Xiao in the car will patiently and briefly introduce the vent of the car water tank to his friends. steam

Water tank is an important part of water-cooled engine. As an important part of the cooling circuit of water-cooled engine, it can absorb the heat of the cylinder block and prevent the engine from overheating. Because of the large specific heat capacity of water, the temperature of the engine will not rise much after absorbing the heat of the cylinder block. Therefore, the heat of the engine passes through the liquid circuit of cooling water, with the help of water as the heat carrier, and then dissipates heat by convection through a large area of fins, thus maintaining the appropriate working temperature of the engine.

principle of operation

When the engine water temperature is high, the water pump repeatedly pumps water to reduce the engine temperature. The water tank is a hollow copper tube. High temperature water enters the water tank, and the air is cooled and circulated to the cylinder wall of the engine. In order to ensure the engine, if the water temperature is too low in winter, the water circulation will be stopped at this time to prevent the engine temperature from being too low.

Automobile water tank structure

The key of automobile water tank is composed of radiator core, water pipe, cooling blades, upper water tank and lower water tank. The upper water tank is on the radiator, and the water pipe connects the upper water tank with the water tank below the radiator. Hot water flows from top to bottom to the lower water tank and becomes warm water, which cools the blades to form an air duct. With the help of the suction of the fan and the year-on-year wind speed in front of the vehicle, a large range of cold air absorbs the heat of cooling water flowing through the water pipe through the air outlet, and then

Automobile water tank power supply

The function of the cooling system is to dissipate the redundant and useless heat of the engine, so that the engine can work at room temperature at various speeds or driving conditions.

The water tank is the heat exchanger of water-cooled engine, and the normal working temperature of the engine is maintained by air convection cooling. Once the engine cooling water in the water tank boils, evaporates and expands at high temperature, and the pressure exceeds the set value, the water tank cover (A) overflows to release the pressure, which shortens the cooling water and prevents the cooling system pipeline from bursting. Precautions for driving at ordinary times: Is the pointer of engine cooling water thermometer on the instrument panel normal? If the engine cooling fan fails, the engine cooling water temperature rises or the cooling system pipeline leaks, the cooling water may also be shortened. Before adding distilled water, please pay attention to whether the shortening amount and cycle of cooling water are normal.

Automobile water tank maintenance

1. The radiator should not touch any acid, alkali or other corrosive substances.

2, advocate the use of soft water, hard water should be softened before use, to prevent the radiator internal blockage and scaling.

3. When using coolant, in order to prevent the radiator from corrosion, please be sure to use the long-term antirust coolant produced by regular manufacturers that meets the national standards.

4. In the process of installing the radiator, please don't damage the radiator belt (sheet) or hit the radiator to ensure the heat dissipation ability and tightness.

5. When the radiator is completely drained before water is injected, it is necessary to turn on the drain switch of the engine block first, and then turn it off after the water flows out to prevent foaming.

6. During normal use, the water level shall be detected at any time, and water shall be added after stopping the machine for cooling. When adding water, slowly open the water tank cover, and the staff should stay away from the water inlet as far as possible to prevent the high-pressure steam sprayed from the water inlet from being burnt.

7. In winter, in order to avoid freezing and cracking the core, such as long-term parking or indirect parking, the water tank cover and drain switch should be used to release all the water.

8. The effective environment of standby radiator should be kept ventilated and dry.

9. According to the actual situation, the user should thoroughly clean the radiator core within 1 ~ 3 months. When cleaning, rinse with clean water along the side opposite to the wind direction. Regular cleaning can prevent the radiator core from being blocked by dirt, which will affect the heat dissipation performance and service life of the radiator.

10, the water level gauge should be cleaned every three months or according to the actual situation; Take out all parts and clean them with warm water and non-corrosive detergent.

Undeveloped and replaced rust and sludge in the engine can also damage the cooling system. This is why flushing the water tank frequently is another important requirement for car maintenance-this is often overlooked by many small partners who participate in it personally. Your car cooling system can protect you from high heat damage caused by the engine and make the engine rotate in a moderate temperature range. Keeping the cooling system free from corrosion, accumulation and pollution will make it and the engine in good working condition. Fortunately, there is no need to flush the water tank as frequently as changing oil (once every two years should be enough), and it is very easy to achieve. Please follow the expert's instructions step by step!

1- Process-Start

Start and make sure that the engine is cold. A high-temperature engine means that the water tank is filled with high-temperature antifreeze with extremely high pressure-opening the lid of the water tank may burn you. Cold water can also damage high-temperature engines.

2. Process-Cleaning the water tank

Open and firmly fix the engine cover to prevent accidental sliding. Then, gently wipe off the dead insects and debris collected on the grille of the water tank with a nylon brush and soapy water. Be sure to scrub along the direction of the radiator, not in the opposite direction, because metal is fragile and easy to bend and deform. After cleaning the grille, introduce a mild water flow from the hose above the grille to ensure that all debris has been completely removed.

Although you only flush the water tank once every two years, it is a good idea to clean the water tank grille up and down every 12000 miles.

Process 3- Place the drain pan

It is very important to discharge waste antifreeze correctly. Antifreeze is very toxic, but it is sweet and can attract children and animals. Unattended discharge is not allowed, nor is it allowed to discharge on the ground. Please make sure that the drain pan is not used for any kitchen purpose-disposable drain pan is an ideal choice. The drain pan should also be small enough to be installed under the car.

After finding a suitable drain pan, slide it under the car and place it in the center of the water tank drain valve (also known as the drain plug).

Process 4- Check the water tank cover

As the cover of the water tank, the water tank cover is used to seal and pressurize the antifreeze in the water tank to keep the engine cool. The pressure of antifreeze varies with the engine, and the rated pressure is marked on the top of the cover itself.

The water tank cover contains a spring ring that extends between the wide flat metal at the top and the smaller sealing rubber at the bottom. The tension between the spring and the sealing rubber is the key to keep the cover pressure. Therefore, if both can be easily compressed, it means that the water tank cover is worn and should be replaced. Another phenomenon of replacing the water tank cover is that the sealing rubber is rusty or dry. In most cases, the water tank cover is replaced at least once every two years, so when flushing the water tank, you can make it a part of your daily work. Remember, different water tank covers have different pressure ratings, so be sure to keep these ratings in your car records.

Process 5- Check clips and hoses

The next step is to check the hose and clamp of the water tank. There are two hoses: one is located at the top of the water tank to discharge the high-temperature antifreeze in the engine, and the other is located at the bottom to circulate the antifreeze cooled in the engine. In order to replace the hose, the water tank must be emptied, so please check it before flushing the engine. Therefore, if you find that the hoses are broken or leaking, or the clips look rusty, you can replace them before refilling the water tank. Soft, mushy sticky marks mean that you need a new hose. If you find that only one hose has these marks, please replace two.

Process 6- Drain the old antifreeze

The water tank drain valve (or drain plug) should have an easy-to-open handle. Just tighten the screw plug (please wear work gloves-antifreeze is toxic) and let antifreeze enter the water tray you put under the car in process 4. After draining all antifreeze, replace the plug and put the old antifreeze into the sealable container you prepared nearby. Then put the drain pan under the playback oil plug.

Process 7- Flushing the Water Tank

You are ready to perform the actual flushing! Just pick up your garden hose, insert the nozzle into the nozzle of the water tank and let it flow fully. Then open the screw plug and let the water drain into the drain pan. Repeat the above steps until the water flow becomes clean, and make sure to put all the water used in the flushing process into a sealable container, just like using the old antifreeze. At this point, any worn clips and hoses need to be replaced.

Process 8- Adding antifreeze

The ideal antifreeze consists of 50% antifreeze and 50% water. Distilled water should be used, because minerals in tap water will change the properties of antifreeze and make it unable to work normally. You can mix these ingredients in a clean container in advance, or directly inject them. Most water tanks can hold about two gallons of antifreeze, so it's easy to judge how much you want to use.

Process 9- Cooling System Exhaust

Finally, the residual air in the cooling system should be exhausted. Open the water tank cover (to prevent pressure accumulation), start the engine and let it run for about 15 minutes. Then turn on your heater and turn it to high temperature. This will circulate the antifreeze and let the air in it dissipate. Once the air is pumped away, the vacant room occupied by it disappears, and the vacant room with a small amount of antifreeze can be added with antifreeze. But please be careful, the air released from the water tank will come out, which is quite hot.

Then install the backwater box cover and wipe off the excess antifreeze with a rag.

Process 10- Cleaning and Discarding

Check whether the screw plug leaks or overflows, and discard rags, old clips and hoses, and disposable drip trays. You're almost finished. Proper disposal of used antifreeze is as important as disposal of waste engine oil. Moreover, the taste and color of the old antifreeze are particularly attractive to children. Please don't leave it unattended. Please send these containers to the hazardous materials recycling center! Handling hazardous materials.
