Problems solved by technology

[0003] The electric energy storage device of the electric vehicle is a vehicle-mounted rechargeable battery. The performance of the vehicle-mounted rechargeable battery directly determines the performance of the electric vehicle. During the charging and discharging process, the vehicle-mounted rechargeable battery will cause safety problems such as leakage, combustion and explosion due to heating up. The vehicle-mounted rechargeable battery of the prior art dissipates heat by installing a cooling device and a cooling fan on the battery box, but the cooling effect and efficiency are poor, and the internal temperature of the battery box cannot be lowered in time

Embodiment 1

[0044] refer to Figure 1-Figure 9 As shown, a vehicle battery box of the present invention includes a body 2 and a cover 1 connected to the body 2, the body 2 includes an inner layer structure 21 and an outer layer arranged outside the inner layer structure 21 Structure 22, the inner layer structure 21 and the outer layer structure 22 are barrel-shaped, the inside of the inner layer structure 21 is provided with electric cores, and a wind is formed between the inner layer structure 21 and the outer layer structure 22 channel 3, the air channel 3 is formed on the entire circumference and bottom of the inner layer structure 21, the contact area between the air channel 3 and the inner layer structure 21, outer layer structure 22 is greatly increased, the The outer structure 22 is provided with an air inlet 5 and an air outlet 4, and a fan is arranged at the air outlet 4 or the air inlet 5. Air is discharged from the air outlet 4 through the air duct 3 from the air inlet 5, and ...

Embodiment 2

[0053] The difference between the second embodiment and the first embodiment lies in the structure of the cover body 1 .

[0054] In this example, if Figure 8 and Figure 9 The cover body 1 shown includes a top plate 13 and an outer wall 14 and an inner wall 15 connected to the top plate 13, the inner wall 15 is located on the inner side of the outer wall 14, and the inner wall Layer coaming plate 15 and described inner layer structure 21 sealing connection, described outer layer coaming plate 14 and described outer layer structure 22 sealing connection, described top plate 13 and described outer layer coaming plate 14 and described inner layer coaming plate 15 is an integral structure, and the integral structure of the cover body 1 structure can reduce the number of parts.

Embodiment 3

[0056] Embodiment 3 is a further preferred embodiment of Embodiment 1. The improvement of Embodiment 3 lies in the circumferential air duct 31 , the circumferential air inlet 52 and the circumferential air outlet 42 .

[0057] Such as Figure 1-Figure 3 As shown, a second partition structure 24 is arranged between the outer sidewall of the inner layer structure 21 and the inner sidewall of the outer layer structure 22, and the surface where the second partition structure 24 is located and the first partition The plane where the structure 23 is located is vertical, and the second partition structure 24 is approximately parallel to a part of the side wall of the inner layer structure 21 or the outer layer structure 22, and the second partition structure 24 divides the circumferential air duct 31 is divided into a first circumferential air channel 311 and a second circumferential air channel 312 oppositely arranged, so that the wind resistance of the inner layer structure 21 to t...

Abstract

The invention discloses a battery box for a vehicle, and the vehicle. The battery box for a vehicle comprises a main body and a cover connected to the main body, wherein the main body comprises an inner layer structure and an outer layer structure disposed at the outer side of the inner layer structure, both the inner layer structure and the outer layer structure are barrel shaped, an air duct isformed between the inner layer structure and the outer layer structure, and the outer layer structure is provided with an air inlet and an air outlet, so that the air enters from the air inlet, runs through the air duct, and is discharged from the air outlet. In the battery box for a vehicle, the inner layer structure and the outer layer structure are arranged in a barrel shape, an air duct is formed between the inner layer structure and the outer layer structure and on the entire circumference and bottom of the inner layer structure, and the contact area of the air duct, the inner layer structure and the outer layer structure is greatly increased, so that the forced air flow formed by the fan in the air duct can quickly take away the heat within the battery box, thereby obviously improving the heat dissipation efficiency and heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle battery box and a vehicle. Background technique [0002] Nowadays, the depletion of oil resources and air pollution caused by exhaust emissions have given birth to the development of new energy vehicles. Electric vehicles and hybrid vehicles are getting more and more attention, especially electric vehicles, which are "zero emission" vehicles. And the noise is small, comfortable and clean, easy to operate and maintain. [0003] The electric energy storage device of the electric vehicle is a vehicle-mounted rechargeable battery. The performance of the vehicle-mounted rechargeable battery directly determines the performance of the electric vehicle. During the charging and discharging process, the vehicle-mounted rechargeable battery will cause safety problems such as leakage, combustion and explosion due to heating up. The vehicle-mounted rechargeable battery of the prio...
