Problems solved by technology

[0003] At present, the battery cells in the existing integrated cooling battery box are attached to the heat dissipation plate of the thermal management system to realize the cooling or heating function of the battery system. On the one hand, this arrangement makes the liquid cooling pipe directly placed in the integrated cooling battery box Inside, if the liquid cooling pipe leaks, the cooling liquid will directly soak the battery and battery management system and other components in the battery box, seriously threatening the safety of the battery
On the other hand, the thermal management system of the structure does not cool well

Embodiment 2

[0043] Based on the same inventive concept, this embodiment provides a battery pack, including the battery and the integrated cooling battery case 1 provided in Embodiment 1; the batteries of the battery pack are installed in the battery chamber of the integrated cooling battery case 1, and the integrated cooling battery The shape and size of the box body 1 can be designed according to the number of batteries, and there is no limitation here.

[0044] The battery is installed in the battery chamber of the integrated cooling battery box 1 through the second box body 11. In order to improve the heat dissipation and cooling effect, a layer of heat conduction pad, such as silicon rubber, can also be laid between the battery and the second box body 11. The heat conduction pad can be The heat generated by the battery is quickly transferred to the second box body 11 and the heat is conducted away through the cooling liquid in the cooling cavity, so as to realize rapid cooling of the b...

Embodiment 3

[0047] Based on the same inventive concept, the present invention also provides a vehicle, including the battery pack provided in Embodiment 2, that is, adopting the integrated cooling battery case 1 in Embodiment 1. The present invention does not specifically limit the type and type of the vehicle. It can be any vehicle in the prior art, such as a family car, passenger car, truck, etc. Other unspecified structures of the vehicle can refer to relevant disclosures in the prior art. , no expansion description will be made here.

[0048] In the vehicle provided in this embodiment, the battery case 1 is connected to the vehicle water tank through the liquid outlet 14 and the liquid inlet 13, and a radiator and a heat dissipation valve are arranged in the vehicle cooling circuit, and the radiator and the heat dissipation valve are connected in series; During the process, the embodiment of the present invention can use the radiator to control the cooling flow according to the differ...

Abstract

The invention discloses an integrated cooling battery box body, a battery pack and a vehicle. The integrated cooling battery box body comprises a first box body, a second box body and a sealing plate; the first box body and the second box body define a battery cavity for placing a battery; the second box body is provided with a concave area; the sealing plate seals the concave area, the second box body and the sealing plate are encircled to form a cooling cavity for accommodating cooling liquid; and the battery cavity and the cooling cavity are distributed on two sides of the second box body; a water inlet main flow channel and more than two flow channel branches are arranged in the concave area of the second box body, more than two water inlet flow channel openings are formed in the second box body side by side in the flowing direction of the water inlet main flow channel, and the water inlet main flow channel is communicated with the more than two flow channel branches through the more than two water inlet flow channel openings; and a liquid inlet communicated with the water inlet main flow channel and a liquid outlet communicated with the flow channel branches are formed in the second box body, and damage to the battery caused by leakage of the cooling liquid is effectively avoided through an integrated liquid cooling plate.

Description

technical field [0001] The invention relates to the technical field of electric vehicle power batteries, in particular to an integrated cooling battery box, a battery pack and a vehicle. Background technique [0002] With the widespread use of new energy vehicles, the safety of battery systems in new energy vehicles has received more and more attention. Since the battery generates heat during charging and discharging, in order to ensure the normal operation of the battery system, a liquid cooling system is usually installed on the battery box to cool the battery box. [0003] At present, the battery cells in the existing integrated cooling battery box are attached to the heat dissipation plate of the thermal management system to realize the cooling or heating function of the battery system. On the one hand, this arrangement makes the liquid cooling pipe directly placed in the integrated cooling battery box Inside, if the liquid cooling pipe leaks, the cooling liquid will di...
