Description

Technical Field

[0001] The utility model relates to the field of heat dissipation plates, in particular to a water-cooled heat dissipation plate. Background Art

[0002] New energy vehicles refer to vehicles that use non-traditional fuels, such as electricity, hydrogen, etc. as their power source. Compared with traditional fuel vehicles, new energy vehicles have lower environmental pollution and higher energy efficiency, while hydrogen energy has certain risks, which has led to the vigorous development of electric vehicles. Most electric vehicles have battery packs installed under the vehicle to store energy. When the battery pack is charging and discharging, a large amount of heat will be generated. If the heat cannot be discharged in time, it may cause the vehicle to age naturally or the line to age prematurely. Therefore, a heat sink is needed to cool the vehicle battery pack. Therefore, a water-cooled heat sink is proposed.

[0003] Although the existing heat sink can effectively dissipate the heat of the battery pack and then dissipate it through the wind when the car is driving, the current electric car is stationary when charging, which may cause the heat sink to absorb the heat but fail to effectively discharge the heat. Therefore, it will greatly damage the battery pack and may even cause the car to catch fire. For this reason, technical improvements are urgently needed. Utility Model Content
