Résumé

The inverter controller produces large heat flux during the high-frequency operation of inverter air conditioners and the heat flux should be dissipated in time. The objective of this study is to propose a novel cooling method based on the heat pipe heat sink (HPHS) for the inverter controller. The heat flux of the chips in the controller is transferred to heat pipes by conduction and then dissipated to the ambience by the efficient heat convection between the dense fins and the air. Two types of HPHSs (i.e. vertical U-type and L-type) are designed, and their cooling performance are investigated and compared with the conventional plate-fin heat sink based on simulation. The application of HPHS cooling method in a real inverter air conditioner shows that, L-type HPHS and U-type HPHS can reduce the average temperatures of chips by 7.9 oC and 5.2 oC compared to the conventional plate-fin heat sink, respectively.
