Abstract

The invention discloses a lithium battery silica gel heat conduction structure. The lithium battery silica gel heat conduction structure comprises a substrate, an upper water tank, a lower water tank,a driving device and heat dissipation pipes; mounting holes are formed in the substrate; silica gel sleeves are fixedly arranged in the mounting holes; the upper water tank and the lower water tank are arranged on two sides of the substrate respectively; the upper water tank and the lower water tank are connected to the silica gel sleeves in a sleeving mode; the driving device is embedded in thesubstrate and used for driving the upper water tank and the lower water tank to move along the silica gel sleeves; and the heat dissipation pipes are embedded in the silica gel sleeves in a surrounding mode and are communicated with the upper water tank and the lower water tank. According to the lithium battery silica gel heat conduction structure of the invention, the silica gel sleeves are adopted, and therefore, the contact area of single batteries and the silicon gel sleeves is increased, temperature difference between the batteries is reduced, and it can be ensured that the batteries canwork within a normal working temperature range; and the upper water tank, the lower water tank, the driving device and the heat dissipation pipes are adopted, and therefore, when the working temperature of the batteries is too high, water cooling and air cooling are enabled, so that heat generated by the batteries is discharged out of a system in time.

Description

technical field [0001] The invention relates to the technical field of heat conduction equipment for lithium batteries, in particular to a silicone heat conduction structure for lithium batteries. Background technique [0002] When the new energy vehicle battery is in operation, it needs to be continuously discharged and charged. During the whole working process, the temperature of the new energy vehicle battery changes at any time, and the change is uneven, and local temperature is often too high Or the local cooling is uneven, and the internal temperature of the battery needs to be solved immediately. At this time, the heat-conducting silicone sheet is needed, whether it is between the battery cell or the battery module. , or between the battery module and the battery case, a thermally conductive silicone sheet can be embedded. As long as there is a temperature difference in any position, the thermally conductive silicone sheet can transfer the temperature from high temper...
