Description
The utility model relates to a kind of heat exchanger, relates in particular to a kind of have type bar and welded plate type heat exchanger.
At present, have type bar and welded plate type heat exchanger two kinds of forms are generally arranged, a kind of is to be terminated its Patent right version (91227597.9), all has the type bar on each sheet corrugated cardboard sheet in this kind structure.Another kind be with China " patent of invention " (96103317.7) be the version of representative, have a type bar between per two corrugated cardboard sheets, and adopt integral braze-welded technology manufacturing.In addition, also having a kind of is banding pattern bar not, only has high flange soldering inclined-plane at the corrugated cardboard sheet periphery, adopts integral braze-welded product manufactured.Though these three kinds of plate type heat exchangers respectively have the advantage and the scope of application, and weak point is also all arranged; Be terminated its patent right (91227597.9) though every corrugated cardboard sheet of version on all have the type bar, these type bars are not welded together with corrugated cardboard sheet, the feasibility of its assembling and the reliability of sealing etc. are all undesirable.The weak point of the sort of brazing plate type heat exchanger of banding pattern bar is not; The used raw material of product will be subjected to strict restriction, can not use the sort of under soldering high temperature the more weak material of its intensity make integral braze-welded plate type heat exchanger, otherwise the ripple of heat exchanger will be out of shape because of the compressing of product deadweight under the high temperature of soldering, thereby influences the heat exchange efficiency and the resistance of product.Its main weak point of version that is representative with Chinese " patent of invention " (96103317.7) is; Its type bar height can not be accomplished to be strict controlled on the actual size of two ripple height sums.Though being same set of mould compacting, the ripple height of every corrugated cardboard sheet forms, but its ripple height is subjected to mould and die accuracy to be changed to some extent with the small different of local material of raw material and local material thickness, in these minor variations at random, the ripple height tolerance of single corrugated cardboard sheet generally can satisfy the desired margin of tolerance in joint clearance of brazing, but the stack of two ripple height will enlarge the accumulation effect of this tolerance, even exceeds the tolerance of joint clearance of brazing.And type bar height is difficult to accomplish that it highly can change with the tolerance variation of two ripple height when determining and producing in batches.If type bar height is local a little more than two ripple height, just will cause corrugated cardboard sheet not contact and sealing-off by each contact point of part, thereby will cause product can not pressure-bearing, deform and can't use.Can cause then that a little less than two ripple height the type bar does not contact and sealing-off with the part at corrugated cardboard sheet edge if type bar height is local, product will produce the part and leak outside, and also can't use.Simultaneously, this structure can cause also that to do its bearing capacity of runner of peripheral sealed with brazing with the type bar lower.This structure type bar when assembling is difficult for marshalling, and type bar outward appearance is uneven after the product soldering.In addition, because this structure is between corrugated cardboard sheet, between corrugated cardboard sheet and the type bar, and and forward and backward outer side plate between all exist can relative displacement possibility, easily there are the assembling dislocation in product its endoporus and sealed with brazing face after soldering, even the serious consequence that causes the endoporus product leakage to scrap thus.
The purpose of this utility model provides a kind of novel have type bar and welded plate type heat exchanger.It can satisfy under the temperature of soldering, the material that its elevated temperature strength is lower still can adopt integral braze-welded mode to make the requirement of plate type heat exchanger, simultaneously can also make product have higher bearing capacity and neat outward appearance, avoid causing the leakage of product to scrap because of the possible dislocation of endoporus assembling.Most importantly solution type bar height and ripple height tolerance are difficult for coincideing, thereby cause that the product bearing capacity is low, may cause the problem of product rejection thus.So this constructed products suitable application area is wider, Practical Performance is stronger, and the percent defective of manufacturing process is lower, and profile is neat appearance more.
The purpose of this utility model is to realize like this; A kind of have type bar and a welded plate type heat exchanger, it comprises: heat transferring medium advances, the outlet ozzle, preceding outer side plate, the outer side plate in back, flat plate, the type bar, solder and corrugated cardboard sheet, utilize the architecture basics that all has the type bar in the version that has been terminated its patent right (91227597.9) on each corrugated cardboard sheet, cancel the assembling form and the Type of Welding of (91227597.9) in this version all other, make every type bar all together integral braze-welded with the plate that it faces mutually, by the multilayer corrugated plate, before, the outer side plate in back, the type bar, flat plate, solder and ozzle are welded into integral body, form netted soldering contact point and medium runner, corrugated cardboard sheet, flat plate between the corrugated cardboard sheet, before, the edge of through hole is welded together mutually on the outer side plate in back, form advancing of different medium, exit passageway is characterized in that: all there is the slightly high stretch flanging of gradient at the periphery place of every corrugated cardboard sheet, and the space of placed type bar is all arranged in the flange, the type bar is a solid profile, it highly equals the ripple height of single plate, and the type bar is bent to the shape near space in the high flange of corrugated cardboard sheet, and its assembling form is; The type bar that plays the rigid support effect under brazing temperature is all arranged in the high flange of each corrugated cardboard sheet, and the external sealed with brazing of plate periphery uses solder through integral braze-welded assurance by the sealed with brazing inclined-plane that the high flange of each plate inclined-plane stacks formation.
The utility model has following advantage and good effect: in this structure, the height of a type bar only cooperates the height of a slice ripple, its assembling effect is more identical, the soldering yield rate is higher, can satisfy the sort of under soldering high temperature the more weak material of its elevated temperature strength with integral braze-welded technology, the requirement of making brazing plate type heat exchanger.And because the type bar in every plate only plays the effect of rigid support to ripple in the brazing process of this structure, directly product is not played the effect of external sealed with brazing, so, type bar height tolerance standard in this structure is not very crucial data, even allow the height of this type bar height a little less than a ripple, to allow the ripple height that a little the cost that steps down to may take place under brazing temperature, guarantee that each contact point of product all can be made product obtain higher bearing capacity by soldering securely together.
With the high flange of plate periphery inclined-plane closed assembly, this inclined-plane of each plate is adjacent to mutually, the type bar is built within the inclined-plane, through integral braze-welded, the inclined-plane of these closed assemblies will form the external sealed with brazing of product, and the area of high flange inclined-plane sealed with brazing and soldering strength will be greater than there not being flange to only depend on the area and the soldering strength of type bar and corrugated cardboard sheet periphery sealed with brazing.This structure is after soldering, and the bearing capacity of different medium runner is identical.It has also avoided each runner bearing capacity difference in (96103317.7) structure, makes the low shortcoming of runner bearing capacity of peripheral sealed with brazing of the type bar.
Because the type bar is built-in and plate leans on the perimeter ramps closed assembly, this structure has also been avoided the deficiencies such as endoporus leakage that the assembling of type bar is uneven, outward appearance is whole, plate assembles mutual displacement, the endoporus mutual dislocation causes.Can make product obtain bigger operating pressure and application widely, make the serviceability of product stronger, percent defective in the manufacturing process is lower, and profile is more attractive in appearance, and is going for multiple welding procedure and multiple material aspect product manufacturing and the selection.
