Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, in t...

Abstract

The invention discloses a liquid-cooling plate, which comprises a liquid-cooling plate body. The liquid-cooling plate body is provided with a water inflow section and a water outflow section. The water inflow section is provided with a plurality of water inflow channels in parallel and the water outflow section is provided with a plurality of water outflow channels in parallel. A bypass channel isconnected between the water inflow channels and the water outflow channels. The water inflow channels in parallel and the water outflow channels in parallel can reduce voltage loss and flow resistance, and make temperature cooling more uniform. Part of a lower-temperature cooling liquid in the water inflow channels can be drawn into the water outflow channels. The bypass channel can qualitativelyincrease a voltage loss value, can balance the temperature of the cooling liquids in the water inflow channels and the water outflow channels, reduces the temperature difference between the water inflow channels and the water outflow channels, and makes the cooling effect and the cooling temperature of the water inflow channels and the water outflow channels basically the same. The liquid-coolingplate is applied in the technical field of batteries.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a liquid cold plate. Background technique [0002] As the battery capacity increases, the heat generated by the battery system during charging and discharging also increases further. Therefore, when designing a liquid cooling system, the rated flow required by the battery system also needs to increase accordingly. However, when the flow rate increases, the problem is that the pressure loss increases, especially for the structure connected in series, the increase in pressure loss is more obvious. At the same time, excessively long series flow channels will lead to problems such as excessive temperature difference. [0003] The patent document with the application number CN201820669355.3 discloses a water-cooled radiator plate for electric vehicle power batteries, including a liquid-cooled plate on which parallel upper and lower coolant channels are distributed. , t...
