The theoretical model of the multiple micro-channel parallel flow condenser is established based on the method of distribution parameters

and validity of the model is verified by comparison with the experimental data. Based on this model

the effects of fin height

fin pitch

louver pitch and louver angle on the heat transfer and flow performance of multiple micro-channel parallel flow condenser are investigated. The results show that

as increasing of fin height

the heat transfer rate increases

but the air-side pressure drop decreases; when fin pitch increases

or louver pitch increases

the heat transfer rate and air-side pressure drop all decrease; as increasing of louver angle

the heat transfer rate and air-side pressure drop all increase.
