Working principle of water-cooled radiator:
The water-cooled radiator conducts the heat from the heat source to the water-cooling liquid through the water-cooling plate. The water-cooling liquid is circulated to the water-cooling radiator through the water pump, and there is a fan to It dissipates heat and cools down, and then circulates again, and the heat capacity of water is large, which makes the water-cooled refrigeration system have a good heat load capacity. The direct benefit is that the operating temperature curve of the heat source is very flat.
A water cooling system generally consists of the following parts:
Heat exchanger, circulation system, water tank, water pump and water. A heat dissipation structure can also be added as needed. Because of its physical properties, water has no better thermal conductivity than metal. However, flowing water will have excellent thermal conductivity. In other words, the heat dissipation performance of a water-cooled radiator is directly related to the flow rate of the water-cooling liquid (water or other liquid) in it. Directly proportional, the flow rate of the water cooling liquid is related to the power of the water pump of the refrigeration system. Moreover, the heat capacity of water is large, which makes the water-cooling refrigeration system have a good heat load capacity. It is equivalent to 5 times of the air-cooling system, and the direct benefit is the heat source The operating temperature curve is very flat.
For example, a system using an air-cooled radiator will experience a temperature spike in a short period of time when running a program with a heavy workload, or may exceed the warning temperature, while a water-cooled heat dissipation system will have a large thermal capacity. , the thermal fluctuation is relatively much smaller.
