Description

Technical Field

[0001] The utility model belongs to the technical field of battery cooling, and particularly relates to a water-cooling device for an electric vehicle battery. Background Technique

[0002] An electric vehicle refers to a vehicle powered by an on-vehicle power source and driven by an electric motor, which meets the requirements of road traffic and safety regulations.

[0003] The existing cooling of automotive batteries usually takes away heat through water-cooling. Generally, water-cooling pipes are installed on the batteries. However, the water-cooling pipes are usually exposed outside after installation and are prone to collision or extrusion during use, resulting in the water-cooling pipes being cracked or squeezed and bent. This not only affects the cooling of the battery, but also the water flowing out after the water-cooling pipes are cracked has a certain impact on the battery. Therefore, we have proposed a water-cooling device for an electric vehicle battery. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water-cooling device for an electric vehicle battery. By setting a protection component, specifically, the protection cover plate is installed and fixed, the protection component will play a protective role for the water-cooling pipe, and the side skirt protection shell will play a protective role for the side, preventing the water-cooling pipe from being collided or extruded, avoiding damage to the water-cooling pipe, ensuring the stability of water-cooling, and solving the problem that the water-cooling pipe is prone to collision or extrusion during use, resulting in the water-cooling pipe being cracked or squeezed and bent, which has a certain impact on the battery.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

The protection component includes a protection cover plate. A side skirt protection shell is fixedly connected to the bottom of the protection cover plate. A socket one is opened at each of the four corners inside the protection cover plate. A reinforcement component is arranged on the top of the battery pack housing. The number of the reinforcement components is two. The parts included in the two reinforcement components are the same. A water-cooling controller is fixedly connected to the right side of the top of the battery pack housing. By setting the protection component, specifically, the protection cover plate is installed and fixed, the protection component will play a protective role for the water-cooling pipe, and the side skirt protection shell will play a protective role for the side, preventing the water-cooling pipe from being collided or extruded, avoiding damage to the water-cooling pipe, and ensuring the stability of water-cooling.

[0007] Furthermore, an opening is opened on the right side of the side skirt protection shell. A bolt is inserted into the socket one. Fixed columns are fixedly connected to the four corners of the top of the battery pack housing. Threaded holes are opened at the tops of the four fixed columns. The bolt is inserted into the socket one and threadedly connected to the threaded hole, so as to install and fix the protection cover plate.

[0008] Further, the reinforcement component includes a placement seat, a positioning plate is in contact with the top of the placement seat, a plurality of arc-shaped grooves are formed in the top of the placement seat, and the positions of the positioning plate corresponding to the arc-shaped grooves are arc-shaped. By providing the reinforcement component, specifically, the positioning plate is changed to be on the water-cooling pipe, the nut is threadedly connected to the threaded block, and the positioning plate is clamped and fixed, then the positioning plate fixes the water-cooling pipe, thereby reinforcing the water-cooling pipe and preventing the water-cooling pipe from shaking during the driving of the vehicle, making the water-cooling pipe more stable.
