Abstract
A counterflow plate-type heat exchanger has heat exchange areas which are arranged at an oblique angle relative to the stack direction. This arrangement enables channels to be formed having a smaller width for the passage of fluid than the distance between the plates in the stack direction. As a result, a high rate of heat exchange can be obtained. Corresponding inflow and outflow channels are arranged on opposite lateral sides of the stack. This provides for fluid flow through the stack from one side to the other in a manner such that the entire heat exchange area is contacted by fluid. The channels narrow in the inflow direction and widen in the outflow direction in order to provide optimum flow conditions in the exchanger.
