With the brazed heat exchanger that plate groups of the present invention is formed for unit, adjacent two kinds of heat exchange mediums can be realized and in heat exchanger, flow through the volume size difference of passage (generally, flow of refrigerant is through the passage of less volume, and adjacent heat exchange medium flows through the passage of larger volume).In addition, compared with the heat exchanger of other unsymmetric structures, such channel design both can obtain different volumes, can guarantee that again the bearing capacity of adjacent heat exchange medium channel is consistent, and additionally can not increase the area of adjacent plate welding contact point.Be particularly useful for the special operation condition that some flows have notable difference.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made a detailed explanation.
The heat exchanger of a kind of not isometric(al) channel design as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprise end plate 1, cold media outlet pipe 11, thermal medium inlet tube 12, cold medium inlet pipe 14, thermal medium outlet pipe 13, heat exchange plate group and base plate 2, described end plate 1, heat exchange plate group and base plate 2 stack gradually, soldering forms; Described cold media outlet pipe 11 and thermal medium inlet tube 12 run through the top of end plate 1 and heat exchange plate group respectively, and described cold medium inlet pipe 14 and thermal medium outlet pipe 13 run through the bottom of end plate 1 and heat exchange plate group respectively.
Described heat exchange plate group comprises at least one group of unit sheet bar group, described unit sheet bar group comprises two panels first plate 3 and two panels second plate 4, described first plate 3 and the second plate 4 include the gear slope 31 on main panel and both sides, described main panel is also alternately provided with multiple crest face 32 and multiple trough face 33, described main panel is also provided with the first slope 34 and the second slope 35, two ends, each crest face 32 are connected with the first slope 34 respectively, first slope 34 is connected by horizontal-extending face 36 with the second slope 35, and the length of the first slope 34 is different from the length of the second slope 35, two ends, each trough face 33 are connected with the second slope 35 respectively, described first plate 3 and the second plate 4 main panel knot form axial symmetry, described two panels first plate 3 and two panels second plate 4 are according to crest face faced by trough, crest replaces stacking formation first passage 5 and second channel 6 before and after the mode in trough face.Described first plate 3 and the second plate 4 surface can adopt the mode of groove and raised line adjacent distributions to form first passage 5 and second channel 6, and described first plate 3 and the second plate 4 surface also can adopt the mode of boss and pothole adjacent distributions to form first passage 5 and second channel 6.
First slope, 34 one-tenth splayed arrangements at two ends, described crest face 32, the second slope 35 one-tenth herringbone arrangements at two ends, described trough face 33.In described first plate 3, the length of the second slope 35 is three times of the first slope 34 length, and in described second plate 4, the length of the second slope 35 is 1/3rd of the first slope 34 length.
First plate 3 is out of shape by the corrugated cardboard sheet of conventional symmetric, and its deformed region is positioned on the inclined-plane that crest face is connected with trough face, and deformation tendency is that symmetry direction widens region, crest face, makes the inclined-plane of original rule be deformed into irregular ladder profile.Meanwhile, region, trough face the widening also because of region, crest face of the first plate 3, and oppositely narrow, the irregular notch cuttype curved surface that the trend that also becomes is contrary.Its crest face region projection area is comparatively large, and trough face region projection area is less, but crest face height is identical with the trough face degree of depth.
Second plate 4 is out of shape by the corrugated cardboard sheet of conventional symmetric, and its deformed region is positioned on the inclined-plane that crest face is connected with trough face, and deformation tendency is that symmetry direction narrows region, crest face, makes the inclined-plane of original rule be deformed into irregular ladder profile.Meanwhile, region, trough face the narrowing also because of region, crest face of the second plate 4, and oppositely widen, the irregular notch cuttype curved surface that the trend that also becomes is contrary.Its crest face region projection area is less, and trough face region projection area is comparatively large, but crest face height is identical with the trough face degree of depth.
By the first plate 3 and the second plate 4 according to crest in the face of trough face, the usual manner of trough in the face of crest face is alternately stacked up, the position, trough face of the first plate 3 just in time contacts with the position, crest face of the second plate 4 and forms contact, the gear slope of plate surrounding and the concave, convex platform in plate corner apertures region, as sealing surface (consistent with usual plate type heat exchanger), form adjacent heat exchanging medium passage.First plate 3 is formed second channel 6 by the region, crest face that widens and the second plate 4 by the trough face areas combine widened; Meanwhile, the first plate 3 is then combined as first passage 5 by the region, crest face of narrowing by the region, trough face of narrowing and the second plate 4.The degree of depth because of ripple is all identical, so can find out that the volume of second channel 6 is obviously greater than the volume of adjacent first passage 5.
The brazing plate type heat exchanger be combined into by end plate, base plate, adapter and some plate groups.Thermal medium flows into from thermal medium inlet tube 12, flows through second channel 6, finally flows out from thermal medium outlet pipe 13; Meanwhile, cold medium flows into from cold medium inlet pipe 14, flows through first passage 5, finally flows out from cold media outlet pipe 11.
When differing comparatively large for physical characteristic or two kinds of larger media of traffic requirement difference carry out heat exchange, the heat transfer effect of this Novel asymmetric volume runner heat exchanger involved in the present invention is better than the successful of symmetrical volume flow road heat exchanger.Relative to the plate type heat exchanger of existing asymmetric volume, the Novel asymmetric volume passage plate groups that the present invention proposes, under the not isometric prerequisite of formation, can guarantee that the bearing capacity of adjacent heat exchange medium channel is consistent, and additionally can not increase the area of adjacent plate welding contact point, thus the energy efficiency of whole system can be made higher.Meanwhile, if be used alone the wherein a kind of corrugated cardboard sheet in plate groups, stacking in the mode of Plane Rotation 180 degree, the plate type heat exchanger of the symmetrical volume runner of the routine that also can form, for plate type heat exchanger provides abundanter plate combinatory possibility.
Finally, it should be pointed out that above embodiment is only representative example of the present invention, the present invention can also have many distortion: as described in the length of the second slope 35 only need be greater than the length of the first slope 34; As described in the shape in horizontal-extending face 36 also can be inclined-plane; During as tapered plane that plate as described in relating to contacts with heat transferring medium or skew surface, size, shape, quantity, position can be different etc.Every above embodiment is done according to essence of the present invention any simple modification, equivalent variations and modification, all should think and belong to protection scope of the present invention.
