Abstract

PURPOSE:To secure rigidity and prevent the increasing of pressure loss in a medium path by a method wherein a blade is integlated and connected at the periphery of the neighbored blade and around the opening and a plularity of blade is fastened between reinforcement plates. CONSTITUTION:When a plate type solder is put between respective neighbored blades 10,20 and the solder is heated up to dissolving temperature in a furnace, the blades 10, 20, are integlated and connected at supporting surfaces 17, 27 around the opening 13-16, 23-26 by above soldering work. An eternal connection can be effected also by brazing, gluing or the like. A pair of reinforcement plates 30, 31 which are having almost the same shape and size as the blade are positioned on the both side of the assembling body integlated and connected, thereafter, these are tightened by bolts and nuts 32 each other, and the rigidity of the assembling body is secured. According to this method, the corrugated portions 18, 28 between neighbored blades are only abutted against each other, therefore, a fillet or the like is not generated, the pressure loss of fluid is not increased and decreasing of the heat transfer area may be avoided.

Traditionally, in this type of heat exchanger, the plates are placed in pairs with gaskets interposed between them in order to hold the plates in place and overcome the forces caused by the pressure of the heat exchange medium. It was common for the frames to be tightened using bolts and bolts.

In recent years, in view of the fact that the frame occupies a fairly large proportion of the entire heat exchanger in terms of weight and price, there has been a demand for plate-type heat exchangers that do not use the frame.

In order to meet these requirements, adjacent plates are joined together at their peripheries, around the heat exchange medium introduction and outlet ports, and at the intersections of the corrugations formed on the heat transfer surface, thereby improving heat exchange. It has been proposed to increase the rigidity of the vessel and eliminate the frame.

The supporting points formed by the corrugated portions formed on the heat transfer surface with B < ° cross each other between adjacent plates literally form a point contact,
As a result of brazing, soldering, etc., a large fillet is formed in the core, which obstructs the flow of the medium, increases pressure loss, and reduces the heat transfer area. Moreover, if the fillet is too large, the structure becomes coarse and brittle, and pores and cracks occur due to shrinkage during solidification of the wax, which does not necessarily lead to good results in terms of the rigidity of the heat exchanger.

The present invention aims to provide a plate heat exchanger that does not use a large-scale support device such as a conventional frame and does not increase pressure loss in the medium passage.

The number of these plates is selected to obtain a heat exchanger of desired capacity. The assembly, in which a plate of solder is generally placed between each pair of adjacent plates, is 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 allows the plates to fit along their peripheries and the openings (13-16) (23
~26) around the supporting surfaces (17) (27) are joined together. Instead of using the soldering joining method described above, any other method can be used to permanently join, such as brazing, gluing, etc.

According to this invention, the corrugated portions between adjacent plates simply abut to form a support point,
Since brazing, soldering, etc. are not performed, fillets and the like are not generated, the pressure loss of the fluid is not increased unnecessarily, and a reduction in the heat transfer area can be avoided. Further, desired rigidity can be ensured by tightening the plates between the reinforcing plates, and a large-scale support device unlike the conventional frame structure is not required.
