Abstract

This paper established the mathematic model of the cross-flow plate heat exchanger for indirect evaporative heat exchanger. The mathematic model is solved according to the finite volume method. Through the numerical solution of the mathematic model, the temperature distribution of the primary air and the secondary air in the flow directions are obtained. The efficiency of cross-flow plate heat exchanger for indirect evaporative cooling is analyzed by the å-NTU (the number of heat transfer unite) method. The suitable number of heat transfer unite for the design of the cross-flow plate heat exchanger for indirect evaporative cooling is put forward under the sensible heat exchange condition of the primary air. The suitable number of heat transfer unite of the primary air passage and the secondary air passage is 0.8-2.5 and 0.5-1.7 respectively in actual design of the cross-flow plate heat exchanger for indirect evaporative cooling.
