Micro-channel cold plate battery thermal management system with cross structure and preparation method of micro-channel cold plate battery thermal management system

The invention provides a micro-channel cold plate battery thermal management system with a cross structure and a preparation method thereof, and belongs to the technical field of liquid-cooled battery thermal management systems. According to the invention, the silica gel in the loading mold is mixed with the expanded graphite and the aluminum powder to enhance the heat conduction, and by adding two different heat-conducting media, namely the expanded graphite and the aluminum powder, the viscosity of the silica gel can be reduced while the heat conductivity coefficient of the silica gel is ensured, and the potting difficulty is reduced; the space between the batteries and the micro-channel cold plates is filled with the loading mold so as to reduce heat transfer resistance, the cooling medium is driven by the water pump and flows into the micro-channel cold plates after flow is adjusted through the flow control valve, the micro-channel cold plates penetrate through gaps between the batteries of the battery mo
