By using the finite differece calculation, the investigation of the configuration of copper heat transfer block were carried out to realize large heat flux for the phenomena having high heat transfer section was trapezoidal and the measuring method of the so-called extrapolation method in which coefficient and the high precision of measurement. The form of the heat tranfer block whose cross-the heat transfer quantities were determined by the measurement of the internal temperature distribution were selected as a subject. Although the relatively large temperature distribution was occurred on the heat transfer surface for the block having trapezoidal section, it was shown that the surface temperature uniformity was realized satisfactorily with the addition of the notches at the edges of the surface. Furthermore, the effects of the geometrical and the thermal non-dimensional parameters were clarified. As a result, the configuration of the block and its ranges of dominant parameters showing the good thermal performance were determined.
