Heat exchangers with minichannel and microchannel flow passages are becoming increasingly popular due to their ability to remove large heat fluxes under single-phase and two-phase applications. Heat Transfer and Fluid Flow in Minichannels and Microchannels methodically covers gas, liquid, and electrokinetic flows, as well as flow boiling and condensation, in minichannel and microchannel applications. Examining biomedical applications as well,...

In this century, energy saving and environmental protection are the most interesting topics in scientific technology field. One of them is heat exchangers topic. Thus, nowadays, the conventional heat exchangers have been quickly replaced by microchannels heat sinks which giving smaller size and better heat transfer behaviors. Therefore, here are much researches focus on microchannels heat sinks, especially in boiling process, as present below.

Experiments on expansion and superheat processes of a transcritical CO2 air conditioning system were done. In this study, the cross-sectional area of the expansion valve reduces from 8.195 to 0.091 mm2, the cooler pressure increases and the evaporator pressure decreases; the pressure difference between cooler and evaporator increases

In this paper, the effects of mass flow rate on heat transfer behaviours for two phase flow in rectangular microchannels were investigated by numerical simulation and experiments. The optimal approach for searching the best value of mass flow rate was studied. It was indicated that the rectangular microchannel heat sink with the mass flow rate of G = 0.4 g/s is the best choice for designing (Based on the fixed parameters as mentioned above)...
