Thermal Performance Research of a New V-type Internal-concentrating CPC Heat-pipe Evacuated Tube Collectors
Based on the study of tube-type CPC, due to gaps between the acceptor and the CPC reflectors, a large number of light leakage losses are produced, this paper designs a new V-type CPC reflectors which can reduce, light leakage loss and heat loss, and make the comprehensive utilization of the advantages of heat-pipe evacuated tube collector, then developing a new V type Internal-concentrating CPC Heat-pipe evacuated tube collectors. First, the design structure is given, and produce the method of calculation of the instantaneous thermal collection efficiency and the total heat loss coefficient by analyzing its heat transfer process. Then in order to get its efficiency curve, the outdoor dynamic performance test is conducted, the test results and the theoretical value is more in line.
