<p>A stacked plate heat exchanger (10) has flow passages for three different fluids formed between the plates (18, 20). Passages for the third fluid (W) are adjacent to both sides of each passage for the first fluid (R1) and each passage for the second fluid (R2). The passages are formed using only two plate surface configurations (18, 20), and proper sealing of adjacent plates at the ports (26, 28, 30, 32, 34, 36) forming the inlet and outlet conduits for the three fluids is achieved by configuring the areas around the ports (26, 28, 30, 32, 34, 36) to define a system of annular platforms (40, 42, 44, 48, 50, 52, 56, 58). For improved heat transfer when the heat exchanger (10) is mounted in the horizontal position, baffles (134, 136) may be formed in the passages for the first (R1) and second (R2) fluids to control and direct the flow of the fluids.</p> |
