Abstract
Local heat transferring zones are provided on a heat transferring face. The zones have prescribed patterns of irregularity, which are different from each other. Resistance corresponding to the flowing velocity of the high temperature fluid is imparted to the high temperature fluid by the patterns of irregularity in the zones. It is possible to distribute uniformly the high temperature fluid to the zones to cause it to flow over the entirety of the heat transferring face so as to obtain a uniform flow rate of the high temperature fluid on the zones, improve the contact efficiency of the high temperature fluid with the heat transferring face and improve the heat transfer efficiency of the high temperature fluid to the low temperature fluid through the heat transferring face, unlike the conventional case that the high temperature fluid does not flow in a uniform state on the heat transferring face due to the biased position for the supply of the high temperature fluid.
