Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model 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, including 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 extend through end plate 1 and the top of heat exchange plate group, and described cold medium inlet pipe 14 and thermal medium outlet pipe 13 extend through end plate 1 and the bottom of heat exchange plate group.
Described heat exchange plate group includes least one set unit sheet bar group, described unit sheet bar group includes two panels the first plate 3 and two panels the second plate 4, described first plate 3 and the second plate 4 all 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 additionally 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 first the length of slope 34 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 constitute axial symmetry, described two panels the first plate 3 and two panels the second plate 4 crest face faced by trough, crest is alternately stacked 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 can also adopt the mode of boss and pothole adjacent distributions to form first passage 5 and second channel 6.
The 34 one-tenth splayed arrangements of first slope at two ends, described crest face 32, the 35 one-tenth herringbone arrangements of second slope 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 deformed by the corrugated cardboard sheet of conventional symmetric, and its deformed region is positioned on the inclined-plane of crest face and the connection of 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 also the widening because of region, crest face of the first plate 3, and reversely narrow, the irregular notch cuttype curved surface that the trend that also becomes is contrary. Its crest face region projection area is relatively big, 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 deformed by the corrugated cardboard sheet of conventional symmetric, and its deformed region is positioned on the inclined-plane of crest face and the connection of 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 also the narrowing because of region, crest face of the second plate 4, and reversely 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 relatively big, but crest face height is identical with the trough face degree of depth.
The trough face faced by crest by the first plate 3 and the second plate 4, trough is alternately stacked in the face of the usual manner in crest face, the position, trough face of the first plate 3 just 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. The trough face areas combine that the region, crest face that first plate 3 is widened and the second plate 4 are widened forms second channel 6; Meanwhile, the region, crest face that the region, trough face that the first plate 3 is narrowed and the second plate 4 are narrowed then combines as first passage 5. Because the degree of depth of ripple is all identical, it is possible to find out that the volume of second channel 6 is significantly greater than the volume of adjacent first passage 5.
The brazing plate type heat exchanger being 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 relatively big for physical characteristic or traffic requirement two kinds of bigger media of difference carry out heat exchange, the heat transfer effect of this Novel asymmetric volume runner heat exchanger involved by this utility model is substantially better than the effect of symmetrical volume flow road heat exchanger. Plate type heat exchanger relative to existing asymmetric volume, the Novel asymmetric volume passage plate groups that the utility model proposes, under constituting not isometric premise, can ensure that the bearing capacity of adjacent heat exchange medium channel is consistent, and will not additionally increase the area of adjacent plate welding contact point, it is thus possible to make the energy efficiency of whole system higher. Meanwhile, if the one of which corrugated cardboard sheet being used alone in plate groups, stacking in the way of Plane Rotation 180 degree, the plate type heat exchanger of the conventional symmetrical volume runner that also can constitute, provide more rich plate combinatory possibility for plate type heat exchanger.
Finally it is pointed out that above example is only representative example of the present utility model, this utility model can also have many deformation: the length of the second slope 35 only need to more than the length of the first slope 34 as mentioned;The shape in horizontal-extending face 36 also can be inclined-plane as mentioned; Such as relating to when the tapered plane contacted with heat transferring medium on described plate or skew surface, size, shape, quantity, position can be different etc. Every any simple modification, equivalent variations and modification above example made according to essence of the present utility model, is all considered as belonging to protection domain of the present utility model.
