Abstract


Heat transfer via liquid-vapor phase change of working fluid and low energy consumption of pump have enabled complicated heat pipe system(CHPS) possess many good qualities, such as energy-saving, highly-effective and controllable. The CHPS has apparent advantages over traditional separated heat pipes on position limits of heat exchangers, insufficient supply of working fluid and poor flexibility to variable working condition.The research background of CHPS is introduced at the beginning and then variety of energy transportation technologies home and abroad are involved in this paper including single-phase loop and two-phase fluid loop. Working fluid in evaporators and condensers of CHPS is driven by pump and special parts are equiped to add a small liquid cycle to the big working fluid cycle. Two experimental setups are designed and developed to testify CHPS’performance in heat recovery and energy transportation. It is found that one CHPS can increase refrigeration capacity of refrigerating machine whose power input almost never change by 36% with only 15Watts pump consumption. At the same time, dehumidification capacity of refrigerating system has increased by 42%. With increasing of the charge ratio, heat flux of CHPS increases linearly at first and keeps constant afterward. As to startup process, CHPS is sensitive to low range power output of pump and will not change when pump is running steadily. Research on CHPS’feasibility, energy-saving property and effectivity has been carried out in this paper and supports for further study thus have been provided.
