| 摘 要： | 分析了应用于信息机房空调系统的热管换热器的流程.热管换热器的总驱动温差为室内外温差,单级热管换热器内部制冷剂的恒温特性导致室内换热器和室外换热器两侧热容不匹配、等效热阻较大,可通过增加热管级数来降低换热器的热容不匹配程度,从而降低等效热阻,提高换热效率.

| Abstract: | 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... |
