Coolers Based on Semiconductor Refrigeration Technology for Electric Vehicle On-Board Chargers

Abstract

In this paper a new type of coolers for electric vehicle on-board chargers is presented, which is based on semiconductor refrigeration technology. Using TEC1-12706 we design a cooler for an on-board charger whose power is 3.3kW. And a thermally driven water cooling system is presented to cool the hot end of the semiconductor chilling plate. Semiconductor chilling plates have the advantages of small size, low weight, dust prevention, seismic resistance, non-noise pollution and non-mechanical wear. So they can obviously improve the performances of the coolers used now. Experiments show that the cooler designed can cool the charger well.
