Embodiment 1

[0022] like figure 1 , figure 2 As shown, an integrated temperature-controlled battery pack includes a box 1 and a battery module 2. The battery module 2 is fixed in the box 1, and the bottom of the box 1 is provided with a liquid for cooling the battery module 2. The cooling pipe 3 and the liquid cooling pipe 3 circulate a cooling liquid, and the cooling liquid is water. The liquid cooling pipe 3 is connected with the flow channel width adjustment mechanism. The cross section of the liquid cooling pipe 3 is rectangular, the liquid cooling pipe 3 is a straight pipe, each box 1 is equipped with four liquid cooling pipes 3 and all the liquid cooling pipes 3 are parallel, and both ends of the liquid cooling pipes 3 are connected to a common liquid collector The two common liquid collecting pipes are the liquid inlet liquid collecting pipe and the liquid discharging liquid collecting pipe respectively. The liquid inlet liquid collecting pipe is connected to a pressurizing pump...

Embodiment 2

[0025] The heat-conducting layer 6 is formed by pouring and curing the heat-conducting structural glue. The rest are the same as in Example 1.

Abstract

The invention discloses an integrated temperature-controlled battery pack, which includes a box body and a cell module. Cooling liquid circulates, and the liquid cooling pipe is connected with a channel width adjusting mechanism. The invention can conveniently adjust the position of the brake light switch, realize fast and accurate adjustment of the assembly position of the brake light switch, improve the assembly quality and shorten the working hours. Compared with the traditional on-off cooling liquid temperature control method, the present invention can keep the cooling liquid flowing in the liquid cooling pipe all the time, without the need for the cooling liquid to repeatedly enter, fill the cooling pipe, and repeatedly pressurize, and save the cost of re-accelerating the pressurization of the cooling liquid Therefore, it can speed up the acquisition of heat balance during heat exchange, improve the response speed of temperature changes, and improve the working stability of the battery pack.

Description

technical field [0001] The present invention relates to a battery, and more particularly, to an integrated temperature-controlled battery pack. Background technique [0002] The liquid cooling system of the battery pack and the box have begun to develop in an integrated manner, but the integration simplifies the system structure, but also brings the problem of serious thermal management energy loss. Due to the sharp expansion of human demand for energy and the increasing environmental pollution, the world has accelerated the development of green and high-performance batteries. The application fields of batteries have extended from digital products to transportation power, energy storage, aerospace, communication backup power, etc. The new energy vehicles that have emerged in recent years are major users of battery products. The battery pack is one of the core components of the new energy vehicle. Among them, the cooling system is an important part of the battery pack, which ...
