Highlights
Heat pipe exchanger has the advantages of high heat transfer efficiency, simple structure, stable performance and low cost [Jian and Luo (2018)], which is one of the best choices for waste heat recovery and utilization of flue gas [Cao (2011)]
Gravity heat pipe depends on gravity to realize the reflux of heat pipe working fluid [Zhang, Liu, Jin et al (2016)], which can work without liquid absorption core, so the gravity heat pipe exchanger has a better application prospect [Zhang and Song (2011)]
In order to investigate the effect of inlet temperature of cold fluid on the heat transfer performance, the following condition is adopted: the inlet speed of hot fluid is 2.5 m/s, the inlet temperature of cold fluid is 293 K and the inlet velocity of cold fluid is 2 m/s
Summary
Heat pipe exchanger has the advantages of high heat transfer efficiency, simple structure, stable performance and low cost [Jian and Luo (2018)], which is one of the best choices for waste heat recovery and utilization of flue gas [Cao (2011)]. Noie pointed out that heat pipe has good heat transfer performance and has important application in the field of waste heat recovery [Noie (2006)]. The mid-temperature heat pipe is used to recover the waste heat of the flue gas. In 2016, Ma et al carried out an experimental study on heat pipe heat exchanger for industrial waste heat recovery. According to the requirements to design the heat pipe exchanger, in the evaporation section, the flue gas mass flow (M1) is 5 000 kg/h, the inlet temperature (T1’) is 470°C, and the selected exit temperature (T1’’) is 230°C. There are 5 rows of heat pipe which are made of carbon steel in the normal temperature section, and the working mid of is water. The original parameters of the heat pipe exchanger are determined
