Abstract
A stacked-plate type heat exchanger is provided in which each of the plates are provided with holes or openings to facilitate the flow of hot and cold fluids therethrough. The plates are separated from one another by spacers of a predetermined thickness. A pair of fluid passages are defined with respect to the spacers as passing through the plates due to the holes or openings provided therethrough. A first distance between any two of the holes in one plate is a constant value and a second distance between any two of the holes in a second plate is a constant value. Each distance between any one of the holes in the first plate and each of the holes in the second plate which is closest thereto is also a constant value. This arrangement increases the efficiency of heat exchange and decreases the loss of pressure.
