What are the advantages of using heat pipes for battery thermal management?

Advantages of using heat pipes for battery thermal management ✔ High heat dissipation efficiency Heat pipes have extremely low thermal resistance (~0.1KW-1) and extremely high thermal conductivity (u003e1000Wm-1K-1), and their heat dissipation heat flux density can reach 50Wcm-2 Above, the heat transfer capacity is much higher than relying on forced air cooling or single-phase fluid convection heat transfer methods. ✔ Fast heating rate The published research data shows that the heating rate of the battery through the heat pipe heat conduction is 1.5 times that of the traditional PTC heating rate. Under 30W heating power, it can heat up 20°C in 3 minutes. If the power is 70W, it can heat up 40°C in 2 minutes, so it can greatly shorten the starting time of electric vehicles in cold environments. ✔Good temperature uniformity Research shows that a micro-channel heat pipe with a length of 1m is heated at one end, and the temperature difference along the length is less than 2℃; a 380cm2 flat heat pipe with an area of u200bu200b1cm2 and a heat generation of 20W is applied to the center For the heat source, the temperature difference across the entire surface is also within 2°C, which reflects the excellent temperature uniformity of the heat pipe.
