A variable thermal resistance flat plate (10) for mounting in a stack of flat plates of a flat plate heat exchanger, wherein the flat plates (10) are sealed together so as to define alternating heat exchanging fluid flow passages therebetween. The variable thermal resistance flat plate (10) is arranged for mounting in the stack, and is characterized by having a heat transfer zone (16) which is formed so as to have a varying thermal length. |
