Claims

[Scope of utility model registration request]

A heat transfer plate body that is integrally assembled by stacking a large number of flat plate pieces having a generally rectangular shape at predetermined intervals and alternately forming two types of passage grooves through which different fluids flow;
It is arranged in a recess formed by a notch formed in the center of one side edge of each plate piece constituting this heat transfer plate body, and a fluid flows from the bottom of this recess into one passage groove. 1. A heat exchanger comprising: a fan for feeding a heat exchanger, wherein both sides of a concave portion in which the fan is disposed are formed with tapered surface portions in a direction away from the fan from the bottom toward the opening.
