Abstract

PURPOSE:To prevent the short pass of a medium and to improve heat transmission performance by mutually connecting neighboring plates at their outer rims and their openings and by providing baffles between the rugged part and the outer rim of a plate. CONSTITUTION:A heat exchanger is composed of two kinds of plates 11A, 11B which are alternatingly stacked. There are openings 13A-16A, 13B-16B that lead the medium to a flow passage at four corners of each plate. The plate material at flat parts 18A, 18B having no rugged part between the heating surfaces 12A, 12B and rims 17A, 17B of the plates 11A, 11B is depressed at a regular interval to form multiple baffles 19A, 19B. When the neighboring plates 17A, 17B are mutually connected by brazing, small spaces (a) between the neighboring plates are filled by the brazing material to form baffles 19A, 19B, fill-in parts (a) and space (b) in an alternating manner. As a result, the short pass of the medium is prevented, and the heat transmission performance is improved because the baffles effectively contribute to the heat transmission.

It includes passageways (g) formed by ridges/grooves (C) extending along the periphery of the plate for joining with adjacent plates. Not only does this passage not contribute much to heat transfer, but it also has less resistance than the flow path section formed by the corrugated portion and has a large number of support points, so it easily allows a short path of the heat exchange medium.

"In joining plates together, a plate of solder is generally placed between each pair of adjacent plates. This assembly is then
The plates are heated in a protective gas atmosphere in a furnace to a temperature at which the solder melts, thereby joining the plates together. This soldering operation joins the plates together along their peripheries and at support points on the support surfaces and heat transfer surfaces around the openings. Instead of using the soldering joint method described above,
Any other method can also be used to permanently join, such as brazing or gluing. By joining the plates in this way, a heat exchanger is provided which is of extremely rigid construction and which can withstand high pressure media without the need for equivalent external support devices. In addition, at the above support point, the adjacent plates may not be joined together and the plate group may be tightened between a pair of opposing reinforcing plates, in which case the brazing etc. will only be done on the face side. Therefore, it is possible to avoid problems such as the formation of fillets of the brazing filler metal near the support points, which increases the pressure loss of the medium. ”
