the heater tank can only be disassembled after the instrument panel is disassembled, and it is best to go to a professional repair shop for disassembly.
The warm air tank is an important heating component in automobile air conditioning. The temperature of water used to cool the engine rises after flowing through the engine, and then it flows into the warm air tank. The fan blows air into the warm air tank to dissipate heat and heat the cab. The existing warm air water tank structure includes upper and lower water chambers and a radiating core located between the two water chambers. The radiating core also includes water pipes communicating with the two water chambers and fins sandwiched between adjacent water pipes. The water in the water chamber storing hot water is led out by the water pipes, and the heat of the water in the water pipes is diffused by the fins. The fan blows the heat toward the fin gap to blow it out, and the water after radiating enters the other water chamber and is discharged from the warm air water tank. At present, the structure of the above-mentioned warm air water tank at the connection position between the water pipes and the water chamber is often in the form of plug-in and welding, and the fins are often fixed between the water pipes in the form of welding. When any one of the water pipes or part of the fins is damaged, the whole warm air water tank needs to be replaced integrally.
