The heat transfer system is one of the key components of a Stirling engine .According to the designing requirements that the power generation reaches 3 kW and the efficiency is greater than 20%for the Stirling engines , it designed the supporting heat exchanger system with a heat receiver , a regenerator , and a cooler .The theoretical power generation was calculated at 4.2 kW, its efficiency reaching 28.6%. In addition , it conducted an experiment of the cooler .Experimental results show that the efficiency of the cooler heat exchanger is up to 93.6%, thus meeting the designing requirements .
