Embodiment 1

[0027] Such as figure 1 As shown, a battery liquid cooling device for an electric vehicle includes a battery box 101, and nine interconnected battery modules are arranged in the battery box 101, and the battery module is composed of a single battery 104 inserted into a battery sleeve 108. The above-mentioned battery modules are arranged in a row, and the liquid cooling pipe 106 is surrounded around the battery modules, such as figure 2 , image 3 As shown, the liquid cooling pipe 106 is a serpentine pipe. The serpentine pipe adopts a two-way arrangement, and the interlayers are arranged in a staggered manner. According to the actual situation, the flow direction of the upper and lower layers of cooling liquid can be changed to obtain the best cooling effect. The battery The sealing connection between the box 101 and the upper cover plate 103 prevents leakage of the phase change material.

[0028] The battery box is filled with porous media, specifically between the battery ...

Embodiment 2

[0032] The difference from Example 1 is that, as Figure 4 As shown, the serpentine tube adopts a one-way arrangement, Figure 5 As shown, a single liquid inlet pipe 102 and a single liquid outlet pipe 105 are provided, and the present invention has the characteristics of convenient processing and compactness.

Abstract

The invention discloses a liquid cooling device of a battery of an electric vehicle. The liquid cooling device of the battery of the electric vehicle comprises a battery box, wherein multiple battery modules connected with each other are arranged in the battery box; the battery modules are formed by nesting battery cells into a battery sleeve; the inner wall of the battery sleeve is laminated to the outer wall of the battery; liquid cooling pipes are circularly arranged around the battery module; porous mediums are filled in the battery box; phase change materials are filled in pores of the porous mediums. The liquid cooling device can meet the temperature control requirement of various batteries, particularly high-power power batteries, is compact in structure and convenient in configuration, and has huge market prospect.

Description

technical field [0001] The invention relates to a cooling device, in particular to a liquid cooling device for an electric vehicle battery. Background technique [0002] Batteries are one of the core components of electric vehicles and hybrid vehicles, and their performance directly affects the performance of electric vehicles and hybrid vehicles. However, due to technical constraints, it is difficult to make major breakthroughs in the performance of power batteries in the short term. Therefore, if the electric vehicle is to be commercialized, it is necessary to ensure that the battery works under optimal conditions to improve its performance and prolong its life. The power battery pack used in electric vehicles is composed of multiple battery modules connected in series and parallel. During the charging and discharging process of the battery, heat will be generated, which will increase the overall temperature of the battery pack, and when the temperature is too high, it wil...
