Oil Cooled Battery Pack

Abstract

The invention provides an oil-cooled battery pack, which includes an upper cover, a box body and a battery pack module. An outwardly protruding functional interface cavity is provided on the upper end of one end surface of the box body, and the bottom of the functional interface cavity faces upwards. Inclined upward at a certain angle, the bottom of the functional interface cavity is provided with a positive output terminal, a negative output terminal and at least one communication connection terminal, heat sinks are provided on both sides of the box, and at least one oil outlet is provided on the end surface of the box near the bottom ;The inner side of the upper cover is provided with heat conduction fins, the outer side of the upper cover is provided with heat dissipation ribs, and the upper cover is provided with at least one water blocking exhaust valve and at least one oil filling port; the battery pack module is placed in the box, and the box is equipped with oily Liquid, oily liquid completely submerges the battery pack module and the oily liquid is in contact with the heat conduction sheet inside the upper cover, and the upper cover and the box body are matched and sealed together. The oil-cooled battery pack of the present invention has simple structure, novel arrangement, convenient installation and good heat dissipation effect.

Description

technical field [0001] The invention relates to a battery pack, in particular to an oil-cooled battery pack. Background technique [0002] As the use of battery packs becomes more and more widespread, the existing air-cooled battery packs have long air-cooled flow channels and difficult to balance the internal flow field, resulting in differences in cooling effects in different areas, large temperature differences in batteries, inability to waterproof and dustproof, and volume Large (as long as the volume occupied by the fan and air duct), high cost and other issues can no longer fully meet the market requirements. For some airtight conditions, such as cruise ships, yachts, and cars, due to poor ventilation, if air cooling is used to dissipate heat, it is difficult to lower the temperature of the battery pack, which will affect the service life of the battery pack and cause use costs. higher. Aiming at the deficiency of the above-mentioned air-cooled battery pack, battery ...
