A New Type of Loop Phase-Change Heat Pipe Radiator Application In Module Design
The background and significance of the R&D and design of a new loop phase transition heat pipe radiator are described,and the circuit topology,composition and main technical parameters of the high-voltage and high current power module are taken as the design input.First of all,the structure,heat transfer principle and technical advantages of the new loop phase transition heat pipe radiator are deeply studied and analyzed.Secondly,the temperature field simulation of the heat dissipation substrate,IGBT module and flow field cloud diagram under full load conditions is carried out with Flotherm simulation software.Finally,the temperature rise test is carried out by building a joint modulation test platform,which verifies the correctness,feasibility and performance superiority of the design scheme.The successful application of the traction power module of this new radiator in the field of rail transit breaks through the limitation that the megawatt-level traction power module can only adopt water-cooled cooling.
