Problems solved by technology

The current mainstream technologies include liquid cooling, air cooling, phase change cooling, etc., and most of the thermal management systems are independently installed in battery modules or battery packs, which not only increases the difficulty of design, but also is not conducive to the needs of compactness and light weight.
[0004] In addition, the thermal management structure is usually located at the bottom of the battery, and the heat dissipation efficiency is low

[0049]According to the battery tray 100 according to one embodiment of the present invention, the heat management part 50 includes a cold pipe 52 and a heat pipe 51, a receiving groove 63 is provided in the separator 60, and the receiving groove 63 has a notch 631, and a part of the heat pipe 51 and the cold pipe 52 are located Another part of the heat pipe 51 inside the slot 63 protrudes from the notch 631 of the receiving slot 63 . Specifically, all the cold pipes 52 are located in the receiving groove 63 of the separator 60, the pipe section of the heat pipe 51 connected to the cold pipe 52 is located in the receiving groove 63, and the other part of the pipe section of the heat pipe 51 protrudes from the notch 631 of the receiving groove 63. into the tray body.

[0050] exist figure 1 and figure 2 In the specific embodiment shown, the partition 60 can be a grid, and the grid includes a horizontal partition 61 and a vertical partition 62 connected vertically to each othe...

[0061] exist Figure 3 to Figure 4 In the specific embodiment shown, the heat management part 50 includes a heat pipe 51 , and the spacer 60 has a receiving groove 63 inside. The heat pipe 51 is at least partly located in the receiving groove 63 , and the receiving groove 63 forms a circulation cavity communicating with the outside.

[0062] As a result, the heat is quickly conducted through the heat pipe 51, and at the same time, the external cooling device is used to send air into the flow chamber to cool down the heat pipe 51, so that the heat pipe 51 can continuously export the heat of the battery, and the heat exchange efficiency is higher.

[0063] Wherein, a part of the heat pipe 51 is located in the spacer 60 , and another part of the heat pipe 51 can be embedded in the tray body.

[0064] Specifically, such as Figure 6 and Figure 7 As shown, a part of the heat pipe 51 is located in the separator 60, another part of the heat pipe 51 can be completely or partially e...

Abstract

The invention discloses a battery tray and a battery pack assembly having the same. The battery tray comprises a tray body; A partition adapted to be connected to the tray body over the tray body; Anda heat management section including a heat pipe, a part of the heat pipe embedded in the partition, and a part of the heat pipe extending out of the partition together with the partition defining a plurality of accommodation spaces on the tray body. The battery tray according to the embodiment of the invention is not only light in weight, good in strength, but also more uniform in heat dissipation.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular, to a battery tray and a battery pack assembly having the same. Background technique [0002] In related technologies, improving the energy density of batteries is an important means of optimizing power batteries. There are two conventional methods for improving the energy density of batteries: one is to use materials with higher energy density; the other is to use materials with higher energy density. The improvement of the battery structure enables the same battery module to obtain higher energy density. Among them, the method usually used to improve the battery structure is light weight and compactness, especially the light weight effect is the best, usually by reducing or removing part of the structural parts, or reducing the thickness of the material. Although the above methods can reduce the weight of the battery pack, However, the strength of the battery pack will also be r...
