초록▼
A heat exchanger plate (2, 4, 6, 8) having undulatory pleats (12) for forming fluid flow passages (18, 20) on opposite sides of the plate (2, 4, 6, 8) is disclosed. The heat exchanger plate (2, 4, 6, 8) is improved by providing the side walls (38, 42, 44) of each pleat (12) with a uniform slope. By
A heat exchanger plate (2, 4, 6, 8) having undulatory pleats (12) for forming fluid flow passages (18, 20) on opposite sides of the plate (2, 4, 6, 8) is disclosed. The heat exchanger plate (2, 4, 6, 8) is improved by providing the side walls (38, 42, 44) of each pleat (12) with a uniform slope. By this arrangement, the plate is provided with improved distortion resistance and fluid flow capacity. Method and apparatus for forming the pleated plates are also disclosed for using a pair of non-uniform donative fluid passage forming blades (34″and 36″) mounted for relative oscillatory movement with respect to a recipient fluid passage forming blade (40″) wherein the clearance between each blade is uniform throughout the entire length of each blade. By making the blade clearance constant the slope of pleat sidewalls may be constant even though each pleat follows a curvilinear path in plan view.

A heat exchanger plate (2,4,6,8) for forming a barrier between donative recipient fluids flowing through the heat exchanger and for forming fluid flow passages (18,20) arranged to cause heat transfer through the plate from the donative fluid to the recipient fluid, said plate (2,4,6,8) including und
A heat exchanger plate (2,4,6,8) for forming a barrier between donative recipient fluids flowing through the heat exchanger and for forming fluid flow passages (18,20) arranged to cause heat transfer through the plate from the donative fluid to the recipient fluid, said plate (2,4,6,8) including undulatory pleates (12) forming a set of donative fluid flow passages (20) on one side of said plates and a set of recipient fluid flow passages (18) on the other side of said plates interleaved with the donative fluid flow passages (20), each flow passage (18, 20) being bounded on opposite sides in plan view by the side walls (38, 42, 44) of a pleat (12) and having a central axis in plan view extending along a continuous curvilinear path between separate points on the plate perimeter, characterized in that the slope of each said side wall (38, 42, 44) of each said pleat (12) is constant along the entire length of the flow passage (18, 20), wherein the slope is measured in a plane perpendicular to the central axis of the corresponding flow passage (18, 20).
