With the continous development and utilization of geotemperature energy in recent years, heat exchanger, as an important unit of ground source heat pump system, its style and type are increasing rapidly. At the same time, in the field of geotemperature energy exploitation in cold regions, due to some defects of traditional heat exchangers in the structural design and the use, the ground source heat pump system in cold regions can hardly reach the design goal. So it was urgent to develop an efficient and economical heat exchanger suitable for geotemperature energy collection in cold region. On the basis of the geological conditions in cold regions and the performance demands of heat exchanger, an efficient geotemperature energy heat exchanger for cold regions is developed. The paper introduces this heat exchanger about its structural style, technical parameters, installation and application and so on.
