Description

technical field [0001] The invention relates to the technical field of coolers, in particular to a fresh water cooler and an expansion tank thereof. Background technique: [0002] A cooler is a type of heat exchange device used to cool a fluid. Usually water or air is used as coolant to remove heat. It can be mainly divided into shell and tube coolers, plate coolers and air-cooled coolers. Cooler is a heat exchange device commonly used in metallurgy, chemical industry, energy, transportation, light industry, food and other industrial sectors. It is suitable for different working conditions such as cooler, condensation, heating, evaporation, waste heat recovery, etc. It is widely used in high-power silicon rectifiers, induction furnaces and intermediate frequency furnaces and other large electrical equipment as pure water, water air, oil water for cooling protection , Oil air cooling device.

AI Technical Summary

Problems solved by technology

[0003] In the actual application process, in the practical process of the cooler, because the interior of the cooler is a relatively sealed system, if the sealing performance is not good, the coolant will overflow from the cooler, and the cooling effect is not obvious. In order to ensure that the cooler The heat exchange efficiency and heat exchange quality must ensure that the cooler has excellent sealing. In addition, during the cooling process, because the temperature of the fluid is not the same, the temperature in the cooler will rise during cooling. If the temperature If the increase is large, it will cause the pressure in the cooler to increase. If the pressure is not released in time, it may cause an operation accident.
