For the air cooling of electronic equipment, the pressure drop and heat transfer performance of the equipment are important factors. Recently, the authors carried out experimental studies on the pressure loss of a rectangular block on the wall of prarallel channel having height B. The effects of the opening ratio β= 1-H/B and the side/height ratio of the cylinder C/H on the pressure loss coefficient ζ were clarified. In the present paper, the effect of the opening ratio β on the pressure drop and heat transfer of a rectangular block is investigated. The optimum opening ratio β for the performance of the heat transfer is examined at constant pumpimg power for the basic geometry of a rectangular block. The maximum heat transfer is obtained at the opening ratio β=0.32.
