A heat exchanger especially adapted for use in combination with a transmission such as a hydraulic torque converter. A plurality of generally flat cooling cells are stacked upon each other, each cell including a pair of plates sealed together about their outer periphery and forming therebetween a fluid flow space. Each cell includes a separate inlet opening and outlet opening passing completely therethrough in a direction perpendicular to the direction of stacking. In the stack, all of the inlet holes communicate with each other to form the inlet while all of the outlet holes communicate with each other to form the outlet. A sealing device encircles each opening in each space between the cells. The sealing means can include a pair of concentric rings between which an opening can be provided through the cells without communicating with the interior thereof, for draining leaking fluid to atmosphere. The individual cells are of the same shape so that any selected number thereof can be utilized depending on the desired capacity of the heat exchanger. Within the cells, a spacing structure surrounding each opening spaces the plates apart providing both a space for fluid flow therepast between the opening and the cell interior and a leakage flow path therethrough which does not communicate with the cell interior. The spacing structure may be a separate member. Alternatively, in one arrangement wherein the cells are formed only by two plates appropriately stamped out and mated together, the stamping can include shaping to form the spacing structure.
