Description

Technical Field

[0001] This application relates to the field of battery thermal management, and in particular to a high-efficiency liquid-cooled dual-channel battery cooler. Background Technology

[0002] Energy storage battery packs generate a significant amount of heat during operation. Without effective heat dissipation, these packs may operate at high temperatures for extended periods, negatively impacting their efficiency and lifespan. Therefore, effective heat dissipation is a crucial issue in battery pack technology.

[0003] Traditional air-cooled heat dissipation methods have low heat dissipation efficiency and cannot meet the heat dissipation requirements of high-energy-density battery packs. Although liquid-cooled coolers have better heat dissipation effects, in practical applications, there is often a problem of the battery pack being cold at the bottom and hot at the top, resulting in an unsatisfactory cooling effect. This is because the liquid cooling plate is usually placed at the bottom of the battery pack, where cold air (or coolant) is cooled at the bottom, while hot air (or heated coolant) is at the top, resulting in insufficient heat exchange and uneven temperature distribution in the battery pack. Utility Model Content

[0004] To address the above issues, this application provides a high-efficiency liquid-cooled dual-channel battery cooler.

[0005] The high-efficiency liquid-cooled dual-channel battery cooler provided in this application adopts the following technical solution:

[0012] Preferably, the fixing rod is positioned within the sliding opening and moves within it, with the bottom end of the fixing rod penetrating the sliding opening and extending downwards to be fitted with a nut.

[0013] Preferably, a battery pack is placed between the two L-shaped brackets.
