<p>A novel heat exchanger using parallel small refrigerant channels has recently been developed for high performance air conditioning systems. However, due to non-uniformly heat load among channels, boiling flow tends to be unevenly distributed in parallel channels. This phenomena makes accurate prediction of heat transfer capacity difficult. In this study, experiments on flow boiling in non-uniformly heated two parallel mini-channels were carried out, and averaged heat transfer coefficients in two channels were investigated. When non-uniformly heat load was applied, dryout occurred in relatively wide range in a higher heated channel. As a result, the averaged heat transfer coefficients in non-uniformly heated channels tended to reduce compared with those under the uniform heat flux conditions of the same averaged heat fluxes.</p>
