发明名称	Plate for heat exchangers - has adjoining plates with holes of different sizes to accommodate burrs on edges of holes
摘要	The heat exchanger is constructed from plates mounted side by side with the holes in the plates in line for the through flow of the heat exchanging medium. The plates and the holes in the plates are produced by stamping which leaves a burr on the edge of the hole. - This burr prevents adjoining plates from being pressed close together. This problem is overcome by making the hole (3) in one of the plates larger than the hole in the other plate. The plates are then arranged so that the burred edge of the smaller hole (2) projects into the larger hole. (3pp Dwg.No.2/2)
