TY - JOUR TI - COMPARISON OF HEAT TRANSFER EFFICIENCY BETWEEN HEAT PIPE AND TUBE BUNDLES HEAT EXCHANGER AU - Wu Zhao-Chun AU - Zhu Xiang-Ping JN - Thermal Science PY - 2015 VL - 19 IS - 4 SP - 1397 EP - 1402 PT - Article AB - A comparison of heat transfer efficiency between the heat pipe and tube bundles heat exchanger is made based on heat transfer principle and the analysis of thermal characteristics. This paper argues that although heat pipe has the feature of high axial thermal conductivity, to those cases where this special function of heat transfer is unnecessary, heat pipe exchanger is not a high efficient heat exchanger when it is just used as a conventional heat exchanger in the industrial fields. In turn, there are some deficiencies for heat pipe exchanger, such as complicated manufacturing process, critical requirements for manufacturing materials, etc. which leads to a higher cost in comparison to a tubular heat exchanger. Nonetheless, due to its diverse structural features and extraordinary properties, heat pipe exchanger still has wide applications on special occasions.
