Design And Performance Research Of Tube Fin Type Of Heat Pipe Heat Exchanger

With society development, the problem on energy source utilization and environmental pollution become more and more serious. more and more attentions are drawn to energy saving and environmental protection. As an efficient heat transfer equipment, heat pipe heat exchanger has applied in many realms of heat recycling and presented lots of advantages.According to the present situation of the heat transmission equipment without considering the dust removal function, a gravity type heat pipe heat exchanger has be designed in the paper. Compared to traditional heat pipe heat exchanger, the new equipment can add fins strengthening heat transfer conveniently. The new equipment increasing the dust removal function while the effect of heat transfer was no change. To achieve heat recycling sufficiently, carrying out investigation on the heat pipe heat exchanger is significant.this issue developed a new heat pipe heat exchanger, and made numerical simulation by the software of FLUENT. This new type heat exchanger not only has high thermal efficiency, but also has certain dusting ability, its internal heat pipe adopting spiral finned tube form, the flue gases side and water side are circular runner. This kind of unique internal structure made the dust particles in the flue gases easy to deposit on the surface of spiral finned tube and in wall, and in the pull of gravity the dust particles falls down to the ash hopper. In two kinds of heat pipe heat exchanger on economic and environmental benefit analysis new heat pipe heat exchanger in heat transfer to the dust removing function than the ordinary heat pipe heat exchanger excellent.Based on the model of heat exchange design and fluent simulation analysis verified the model of heat pipe heat exchanger structure rationality and feasibility.
