Abstract

The invention relates to the technical field of heat dissipation devices, in particular to a battery heat dissipation device utilizing liquid metal. The battery heat dissipation device utilizing liquid metal provided by the present invention includes an electromagnetic pump, a heat conduction plate, and a cooling box with an upper opening and an accommodating cavity. Both the heat conduction plate and the cooling box are constructed with a thin hollow layer filled with liquid metal; the heat conduction plate It is arranged above the cooling box, and the hollow thin layer of the heat conduction plate communicates with the hollow thin layer of the cooling box through a telescopic conduit to form a circulating heat conduction pipeline; the outer wall of the cooling box is provided with a heat sink connected with the circulating heat conduction pipeline ; The electromagnetic pump is used to drive the liquid metal to circulate in the circulating heat conduction pipeline. This application uses liquid metal as the medium for storing heat and conducting heat, so that the heat generated by the battery during operation can be quickly dissipated to the environment, and the heat dissipation efficiency of the radiator can be improved; the stretchable conduit can be stretched according to the size of the battery Or compression adjustment, which in turn is suitable for various types of batteries.

Description

technical field [0001] The invention relates to the technical field of heat dissipation devices, in particular to a battery heat dissipation device utilizing liquid metal. Background technique [0002] At present, there are mainly the following types of battery heat dissipation technologies in practical application: gas cooling, liquid cooling and phase change material cooling. [0003] Gas cooling is the most common heat dissipation method, generally by installing a cooling fan to force air convection cooling, but the heat transfer coefficient between the battery and the air is low, so the cooling and heat dissipation effect is not good; liquid cooling uses liquid with relatively high thermal conductivity The main method is to directly or indirectly contact the battery to dissipate heat. The main method is to arrange jackets around the modules or arrange heat transfer tubes between the modules. However, liquid cooling generally uses insulating liquids with high viscosity an...
