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. Negative Effects

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 cross-section tapered liquid-cooled plate that can work on both sides, including an upper cover plate, a lower cover plate, a plate body, a left header and a right header, and the upper cover plate It is arranged above the plate body, the lower side cover plate is arranged under the plate body, the left and right collectors are respectively arranged on the left and right sides of the plate body, and the plate body includes two layers of microchannel partitions , the cooling liquid flows in opposite directions in the upper and lower microchannels, and the cross-sectional area of ​​the two layers of microchannel partitions in the direction of liquid flow gradually decreases. The double-sided cross-section tapered liquid cold plate of the present invention can work on both sides simultaneously while cooling the battery module more uniformly. Since one liquid cold plate can cool two batteries at the same time, the total number of liquid cold plates required by the battery system is greatly reduced, which can greatly reduce system space occupation and power consumption, and is conducive to the development of lightweight new energy vehicles.

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...
