Abstract:

In order to enhance the understanding of influential factors that affect the thermal performance of the jet cold plate,the effects of the jet distance on thermal performance and resistance of the jet cooling plate are studied through experiments, and the uniformity of the thermal performance of the jet cooling plate is analyzed. Experimental results show that:(1) in the case of the same flow rate, as the jet distance increases, the total thermal resistance of the jet cooling plate in the existing structure increases too after it decreases firstly,and there is a minimum value when the jet distance is 1.5 mm;(2) the resistance value of the jet cooling plate decreases when the jet distance increases,but the effect of the jet distance is small;(3) there exists a certain unevenness of the thermal performance of the jet cooling plate in the direction of flow,and the cooling capacity in the inlet side is slightly higher than that in the outlet side.
