Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a cooling device for electrical equipment. Background Art

[0002] Electrical equipment generates a large amount of heat during operation. If this heat is not dissipated in time, it will have a serious impact on the performance and life of the equipment. The cooling system is a very important part of electronic products. It can ensure the normal operation of electronic components and avoid failures due to excessive temperatures.

[0003] With the advancement of technology and the development of electrical equipment, the requirements for cooling devices are becoming higher and higher. There are many ways to design cooling systems. The air flowing in contact with the air is cooled by the delivery of coolant, thereby dissipating heat from the electrical equipment.

[0004] Among them, during the use of the cooling device, the coolant is directly transported to the next use after circulating back, so that the residence time of the coolant that has just returned is short, and the returned coolant may not have dropped to the same temperature as other coolants. Such repeated circulation will reduce the heat exchange effect between the coolant and the air during the transportation process, thereby leading to subsequent impact on the heat dissipation of electrical equipment.
