Description
Technical field
The present invention relates to a kind of plate type heat exchanger, relate in particular to a kind of plate type heat exchanger that utilizes welding or soldering tech to make.
Background technology
The plate type heat exchanger of this utilization welding or soldering tech manufacturing is to fit together with the some heat exchange plates that are roughly rectangle or square and other shapes and have a fillet, on heat exchange plate, has heat exchange structure, by heat exchange plate on heat exchange structure form with concavo-convex brace rod bubble clocklike, by heat exchange plate on heat exchange structure form with ripple, in Figure of description of the present invention, the heat exchange structure on the heat exchange plate is formed with ripple.Also has the inclined-plane that is used for the periphery sealing at the heat exchange plate periphery, between each heat exchange plate, be placed with the low melting point solder, these heat exchange plates by the characteristic that is heated and utilizes the low melting point solder soldered or soldering also can use glutinous stick or gasket seal to reach connection and sealing effectiveness between each heat exchange plate together.
When the plate type heat exchanger of utilization welding or soldering tech manufacturing is heated to uniform temperature, solder between each heat exchange plate will be melted and flow but each heat exchange plate material itself can't melt, because the solder between each heat exchange plate always has certain thickness, to make between each heat exchange plate after the solder fusing and form the gap, the size in this gap just in time is the thickness of this solder.Guarantee welding or brazing quality in order to eliminate these gaps, thereby each heat exchanger plates sector-meeting is moved mutually and is close to and eliminated these gaps when welding or brazing plate type heat exchanger under the effect of anchor clamps and counterweight and deadweight.These solders that once were melted will be set on each contact point and contact-making surface of each heat exchange plate by capillarity when this plate type heat exchanger is cooled, solder and each heat exchange plate be mutually dissolving and diffusion on each contact point and contact-making surface, with each contact point of each heat exchange plate and contact-making surface soldering together and form mutual connection and sealing.
Textural classification by present heat exchange plate periphery sealing inclined-plane can be divided into 2 classes with welding or brazing plate type heat exchanger, wherein the heat exchange plate of first kind welding or brazing plate type heat exchanger has a circle sealing inclined-plane at periphery, on the sealing inclined-plane without any other turnup structure, the heat exchange plate of welding of second class or brazing plate type heat exchanger also has a circle sealing inclined-plane at periphery, but also has a circle turnup structure on the sealing inclined-plane.
The weak point of first kind welding or brazing plate type heat exchanger is; Such heat exchange plate is when carrying or assembling, thus the yield rate of the sealing inclined-plane of heat exchange plate periphery impaired easily deform influence welding or soldering.When assembling piecewise, be difficult for simultaneously keeping and be difficult for checking whether being stacked of level and opposing parallel of each heat exchange plate.If can not keep level and opposing parallel between each heat exchange plate, local sealing-off takes place and makes the percent defective of this plate type heat exchanger higher in this plate type heat exchanger easily after welding or soldering.
Though the second class welding or brazing plate type heat exchanger have overcome the weak point of first kind welding or brazing plate type heat exchanger, its weak point is after having added this circle turnup structure on the sealing inclined-plane; The angle on each heat exchange plate of low melting point solder fusing back each heat exchange plate periphery sealing inclined-plane when moving mutually and being close to trace thereupon changes, on the heat exchange plate periphery sealing inclined-plane especially the turnup structure on the sealing inclined-plane, four fillet places will limit the possible variation in welding or brazing process of sealing bevel angle, each heat exchange plate can not well be relatively moved and be close to when welding or soldering, will cause the percent defective of this welding or brazing plate type heat exchanger higher at last.
Summary of the invention
Cause the higher deficiency of percent defective in order to overcome existing welding or brazing plate type heat exchanger owing to the reason of perimeter ramps turnup structure, the invention provides a kind of plate type heat exchanger with special turnup structure.
The technical solution adopted for the present invention to solve the technical problems is; Have on its heat exchange plate of plate type heat exchanger of special turnup structure and include; Ripple or concavo-convex brace rod bubble, hole, angle, heat exchange plate fillet and periphery sealing inclined-plane is characterized in that: on the sealing inclined-plane of heat exchange plate linear peripheral section turnup structure is arranged, but do not have turnup structure on the sealing inclined-plane at four fillet places of heat exchange plate.
In order to make each heat exchange plate can be easier under the effect of brazing jig and counterweight move mutually and be close to, sealing on the partially sealed inclined-plane that the inclined-plane is connected at the sealing inclined-plane and the straightway of four fillets of heat exchange plate periphery still can not have turnup structure.
On heat exchange plate linear peripheral section sealing inclined-plane, the form of fracture of turnup structure can be a horizontal flange that connects with cambered surface or inclined-plane, or only be a cambered surface and inclined-plane, the cross section of this turnup structure and shape can be designed and manufactured into any suitable form on demand.
The present invention has following advantage and good effect:
Turnup structure on the straightway sealing inclined-plane can be strengthened the intensity on inclined-plane, avoids the inclined-plane to be damaged distortion, simultaneously can be with each heat exchange plate of stacked visual examination of regular turnup structure closed assembly quality of opposing parallel whether.
Because the sealing inclined-plane at four fillet places itself just has reasonable intensity, four fillet places also can resist issuable destructiveness when carrying and assemble even without its intensity of turnup structure on the sealing inclined-plane.
Owing on the sealing inclined-plane at four fillet places, do not have turnup structure, each heat exchange plate periphery comprises that the inclined-plane at fillet place all can easier change the angle on sealing inclined-plane in soldering, each heat exchange plate can easier be moved and be close to mutually, eliminate because solder is flowing in the gap of causing between each heat exchange plate, can make plate type heat exchanger have higher welding or soldering yield rate.
