Objective To establish the heat transfer model for liquid cooling gannent(LCG) and,basing on this model,to find the relations between the design parameters and heat removing,as well as that between the design parameters and heat transfer efficiency. Method Heat transfer process of the LCG was analyzed according to engineering facts.Result The relations between the design parameters and heat removing,and also that between the design parameters and heat transfer efficiency were interelative and the optimal values of the parameters were essential to the design of LCG. Conclusion The results might be useful in the design of LCG in extra vehicular activity(EVA) space suit.
