Problems solved by technology

Usually, a liquid cooling plate is pasted on the two large side walls of the battery and the battery wall on the bottom to cool the battery. In this way, a battery needs 3 liquid cooling plates, causing the cooling structure to take up a lot of space, and at the same time increasing the mass of the system, causing damage to the car itself.

Embodiment Construction

[0021] In the description of this embodiment, it should be understood that orientation words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" etc. The orientation or positional relationship is generally based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this embodiment and simplifying the description. In the absence of a contrary statement, these orientation words do not indicate or imply the referred device Or components must have a specific orientation or be constructed and operated in a specific orientation, so it should not be construed as limiting the protection scope of the present invention; the orientation words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0022] In the description of this embodiment, it should be understood that the use of words such as "first" and "second" to defin...

Abstract

The invention relates to a double-sided working liquid cooling plate with tapered sections on two sides. The heat exchanger comprises an upper side cover plate, a lower side cover plate, a plate body,a left flow collecting pipe and a right flow collecting pipe. The upper side cover plate is arranged above the plate body; the lower side cover plate is arranged below the plate body, the left flow collecting pipe and the right flow collecting pipe are arranged on the left side and the right side of the plate body respectively, the plate body comprises two layers of micro-channel partition plates, the flow directions of cooling liquid in the upper layer of micro-channel partition plates and the lower layer of micro-channel partition plates are opposite, and the sectional areas of the two layers of micro-channel partition plates in the liquid flowing direction are gradually reduced. According to the double-sided working liquid cooling plate with the tapered sections on the two sides, the battery module can be cooled more uniformly, Meanwhile, the double sides can work at the same time. Because one liquid cooling plate can cool two batteries at the same time, the total number of the liquid cooling plates required by the battery system is greatly reduced, the space occupation and electric energy consumption of the system can be greatly reduced, and the development of light weight ofa new energy automobile is facilitated.

Description

technical field [0001] The invention relates to the technical field of thermal management of power batteries, in particular to a double-sided cross-section tapered liquid cold plate that can work on both sides. Background technique [0002] Compared with traditional engine vehicles, pure electric vehicles have no emissions during driving, and have the advantages of simple structure, easy maintenance, and no noise, so they have become the future development direction of the automotive industry. As the main energy storage device of current electric vehicles, the power lithium-ion battery pack has the advantages of high energy density, low self-discharge rate, high charge-discharge rate, long cycle life, etc., but it will generate a lot of heat during its use, while lithium The performance of ion batteries decays quickly under high temperature conditions, which will affect the cycle life and performance of the batteries. Continuous heat accumulation may also cause explosions, f...
