Comparison of Heat-Pipe Cooling System Design Processes in Railway Propulsion Inverter Considering Power Module Reliability

Abstract: In this paper, the effect of the heat-pipe cooling system design processes on the reliability of the power module in a railway propulsion inverter was investigated. The existing design processes for the heat-pipe cooling system guarantee that the junction temperature of power devices does not exceed the maximum allowable junction temperature when the railway propulsion inverter operates under its mission profile; therefore, each step of the design process was reviewed to analyze the effect of the heat-pipe coo… Show more

“…Surendar [14] et al simulated IGBT modules under CTC (conventional thermal cycling) and TSC (thermal In addition to being affected by the working environment, the module will also be affected by long-term temperature changes during use. The high temperature will lead to internal fatigue aging, and the reliability [7][8][9] will be reduced. The main fatigue failure [10,11] of IGBT modules is the failure of the solder layer.…”

“…where 𝑃 is the total power losses of the IGBT and 𝑃 is the total power losses of the FWD. The converter heat dissipation system is a forced air cooling system, and it is mainly divided into the following three steps [6][7][8]: 1) Power electronic device losses calculation; 2) Based on the calculation results, the preliminary design is to select the heat dissipation sink and air channel, etc. ; 3) Conduct the modeling and simulation according to the preliminary design, optimize the design, and then implement the experimental verification.…”
