Performance optimization of separate type heat pipe heat exchanger in plant room with high density of sensible heat load

Analyses the flow path of heat pipe heat exchanger applied to the air conditioning system in plant rooms. The temperature difference of indoor air and outdoor air is the total driving temperature difference. The constant temperature characteristic of refrigerant in heat pipe results in the unmatched problem of thermal capacity in indoor and outdoor heat exchanger, which increases the equivalent thermal resistance of heat pipe. Enhancing the stages of heat pipe can reduce the unmatched problem to some degree and reduce the equivalent thermal resistance, and improve heat transfer efficiency.
