Experiment on heat exchanger parameters of indirect heat transfer system by mixed ice water

Considering the characteristics of hot summer and cold winter in northern area, ice can be saved in winter and used in summer. The indirect heat transfer system is beneficial for reducing carbon, saving energy and protecting the environment. The parameters of heat exchanger were studied in this paper, including the efficiency of heat transfer influenced by wind speed, flow, heat pipe length, windward acreage of heat exchanger. The results showed that more 84% efficiency of heat transfer could be attained when wind speed was 2.54-2.93 m/s, flow rate was 0.72-0.80 m3/h, windward area was 11.93-13.51 dm2, heat pipe length was 7.99-9.95 m. The results can be used for heat exchanger design and application in indirect heat cold exchange system of natural cold resources.
