Problems solved by technology

[0007] During the use of lithium batteries, due to the accumulation of internal gas, the hard square aluminum shell or soft packaging will bulge, and the liquid channel of the heat sink placed in the backlog will reduce the actual channel area, or even completely block it, resulting in heat dissipation. bad

Abstract

A voltage-withstanding flexible liquid cooling fin comprises a cooling fin main body and an aluminum tube disposed on the cooling fin main body and as a water inlet / outlet, the cooling fin main body is composed of two outer aluminum sheets and a middle rubber sheet located between the two outer aluminum sheets, the semicircular structures of the two outer aluminum sheets are oppositely connected to form a channel, the flat sheet structures of the two outer aluminum sheets and the flow channel gap of the middle rubber sheet are oppositely connected to form a liquid channel; the aluminum tube isfixed in the liquid channel and is provided with a gap, the head end / tail end of the liquid channel are collected to the channel, and the head end / tail end of the liquid channel both correspond to the gap of the aluminum tube, and the middle section of the aluminum tube is provided with a blocking piece configured to block the water inlet and the water outlet. The voltage-withstanding flexible liquid cooling fin can be directly put at the internal portion of the battery pack to increase and decrease the temperature of the battery pack, and is simple and reliable in structure, small in size, good in toughness and good in voltage-withstanding effect.

Description

technical field [0001] The invention belongs to the technical field of thermal management of lithium batteries, and relates to a liquid-cooled heat sink. Background technique [0002] The invention relates to lithium battery heat management technology. Lithium batteries include hard square lithium batteries, soft-pack lithium batteries, and cylindrical lithium batteries; liquid-cooled heat sinks also refer to liquid-cooled heat dissipation. The liquid substance in the battery corresponds to air cooling, which belongs to the active high-efficiency heat dissipation technology; heat dissipation refers to cooling and heating, which can control the temperature of the battery so that it can work at a suitable temperature. [0003] At present, the thermal management of lithium batteries is divided into: natural cooling, air-cooled heat dissipation and water-cooled heat dissipation; natural cooling does not have any heat dissipation components, relying on its own heat dissipation; a...
