Thermal stresses in the heated wall of the minichannel

This paper deals with thermal deformations of the heating foil in a heat exchanger with a rectangular minichannel. Flow boiling heat transfer was achieved to maximize the heat transfer coefficient. As confirmed by the experiments, the deformations resulting from the thermal expansion of the heating foil led to local narrowing of the channel, and consequently distorted flow and less effective heat transfer.
