Based on present situation of the compound parabolic concentrator(CPC)type heat collectors

a novel CPC heat pipe type evacuated tubular heat collector has been designed

the structure design and calculation process of light-gathering surface and receiver for said novel heat collector being presented.After analysis of heat collection in the novel CPC heat pipe type evacuated tubular heat collector

the instantaneous efficiency formula of the said novel heat collector has been obtained.The performance comparison between the novel heat collector and the traditional fins type tubular heat collector shows that the novel heat collector has remarkably high efficiency

simple fabricating process

and lower cost.
