A kind of heat exchanger plate chip architecture

Technical field

The utility model relates to a kind of heat exchanger plate chip architecture.

Background technology

When prior art, plate-type heat exchanger needs to reach the different effect of medium free air space (namely, the volume size that the medium of adjacent two kinds of heat exchanges flows through is not identical), it is generally the asymmetric corrugated board structure adopted, makes adjacent two ripples inconsistent. But such mode is not identical because forming the quantity (i.e. contact density) of the welding point of contact of adjacent media passage, it is easy to cause the bearing capacity difference of two kinds of adjacent heat exchange media excessive; In addition, the area of the welding point of contact of adjacent media passage increases, it is easy to causes the thermal resistance of heat transferring medium to increase, is unfavorable for that system heat exchange efficiency improves.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.

A kind of interchanger not waiting volume channel architecture as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprising 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 groups and base plate 2, described end plate 1, heat exchange plate groups become with base plate 2 successively stacking, soldering; Described cold media outlet pipe 11 and thermal medium inlet tube 12 run through end plate 1 and the top of heat exchange plate groups respectively, and described cold medium inlet pipe 14 and thermal medium outlet pipe 13 run through end plate 1 and the bottom of heat exchange plate groups respectively.

Described heat exchange plate groups comprises at least one group of unit sheet bar group, described unit sheet bar group comprises two panels first plate 3 and two panels the 2nd plate 4, described first plate 3 and the 2nd 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 face, slope 34 and the 2nd face, slope 35, each two ends, crest face 32 is connected with the first face, slope 34 respectively, first face, slope 34 is connected by horizontal-extending face 36 with the 2nd face, slope 35, and first the length in face, slope 34 different from the length in the 2nd face, slope 35, each two ends, trough face 33 is connected with the 2nd face, slope 35 respectively, described first plate 3 and the 2nd plate 4 main panel knot form rotational symmetry, described two panels first plate 3 and two panels the 2nd plate 4 are according to crest face faced by trough, crest replaces stacking formation first channel 5 and second passage 6 before and after the mode in trough face. described first plate 3 and the 2nd plate 4 surface can adopt the mode of groove and convex article of adjacent distributions to form first channel 5 and second passage 6, and described first plate 3 and the 2nd plate 4 surface can also adopt the mode of boss and pothole adjacent distributions to form first channel 5 and second passage 6.

The splayed arrangement of 34 one-tenth, first face, slope at two ends, described crest face 32, the 2nd slope 35 one-tenth, the face arrangement of falling splayed at two ends, described trough face 33. In described first plate 3, the length in the 2nd face, slope 35 is three times of the first face, slope 34 length, and in described 2nd plate 4, the length in the 2nd face, slope 35 is 1/3rd of the first face, slope 34 length.

First plate 3 is by conventional symmetrical corrugated cardboard sheet distortion, and its deformed region is positioned on the inclined-plane of crest face and the connection of trough face, and deformation tendency widens region, crest face for symmetrical direction, 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 oppositely narrow, also become the irregular notch cuttype curved surface that trend 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.

2nd plate 4 is by conventional symmetrical corrugated cardboard sheet distortion, and its deformed region is positioned on the inclined-plane of crest face and the connection of trough face, and deformation tendency narrows region, crest face for symmetrical direction, 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 2nd plate 4, and oppositely widen, also become the irregular notch cuttype curved surface that trend 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.

By the first plate 3 and the 2nd 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 contacts with the position, crest face of the 2nd plate 4 and forms contact, the gear slope of plate surrounding and the concave, convex platform in plate corner apertures region, as trim (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 is widened with the 2nd plate 4 and become second passage 6; Meanwhile, the first plate 3 is narrowed region, trough face and the region, crest face that the 2nd plate 4 is narrowed then combine as first channel 5. Because the degree of depth of ripple is all identical, it is possible to find out that the volume of second passage 6 is obviously greater than the volume of adjacent first channel 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 passage 6, finally flows out from thermal medium outlet pipe 13; Meanwhile, cold medium flows into from cold medium inlet pipe 14, flows through first channel 5, finally flows out from cold media outlet pipe 11.

When for, when physical property difference is relatively big or flow requires that two kinds of bigger media of difference carry out heat exchange, the heat exchange effect of the novel asymmetric volume runner interchanger of this kind involved by the utility model is better than the successful of symmetrical volume flow road interchanger. Relative to the plate-type heat exchanger of existing asymmetric volume, the novel asymmetric volume passage plate groups that the utility model proposes, forming under the prerequisite not waiting volume, can guarantee that the bearing capacity of adjacent heat exchange medium channel is consistent, and can not additionally increase the area of adjacent plate welding point of contact, it is thus possible to the Energy efficiency making whole system is higher. Meanwhile, if the wherein a kind of corrugated cardboard sheet being used alone in plate groups, stacking in the way of plane rotates 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 combination possibility.

Finally, it should be noted that above embodiment is only representative example of the present utility model, and the utility model can also have many distortion: the length such as the 2nd described face, slope 35 only need to be greater than the length in the first face, slope 34; Shape such as described horizontal-extending face 36 also can be inclined-plane; During such as the tapered plane that contacts with heat transferring medium on plate as described in relating to or skew surface, size, shape, quantity, position can be different etc. Every any simple modification, equivalent variations and modification above embodiment done according to essence of the present utility model, all should think and belong to protection domain of the present utility model.
