A series of experiments was conducted to investigate the heat transfer character-isics and cooling performance of subcooled liquid,methanol,flowing through rectangular cross-section microchanneled structures machined onto a stainless steel plate. Six different kinds of microchanneled structures were tested. Heat transfer or flow mode transitions were observed for single phase convection when the heating rate or wall temperature was increased. The transitions were found to be induced by or highly associated with the variation in liquid thermophysical properties due to the great rise of the liquid temperature in the microstructures. The influence of such parameters as liquid velocity, subcooling, property variation, and microchannel geometric configuration on the heat transfer behavior,cooling performance and the heat transfer and liquid flow mode transition was experimentally investigated. Flow boiling also was inspected experimentally. The flow nucleate boiling characteristics of liquid through microchanneled structures were some different from those in normally sized tubes and the heat transfer were obviously intensified.
