چکیده
|
A new flow passage arrangement is introduced for parallel-plate heat exchanger for cooling channel walls under uniform heat flux. Heat transfer performance of the new double-pass heat exchanger is compared with those of the corresponding single-pass and original double-pass heat exchangers from wall temperature uniformity viewpoint, because total heat transfer is the same for three types of the parallel-plate heat exchangers. Computed results show that wall temperature in the new double-pass heat exchanger has better uniformity compared to the usual one. Despite the advantage of better uni- formity in wall temperature, power consumption for handling the specified volumetric flow rate within the new double-pass heat exchanger is greater than those are required within the two others.
