Specific embodiment

Below in conjunction with the attached drawing in the utility model embodiment, to the technical solution in the utility model embodiment It being clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model, without It is whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art it is obtained it is all its His embodiment, fall within the protection scope of the utility model.

As depicted in figs. 1 and 2, Fig. 1 is that the stereochemical structure of the preferred embodiment of the utility model heat-exchangers of the plate type is illustrated Figure.Fig. 2 is the schematic cross-sectional view of the preferred embodiment of the utility model heat-exchangers of the plate type.

A kind of heat-exchangers of the plate type provided by the utility model, including expanding tense machine, cabinet 100 and several it is fixed on cabinet Heat dissipation plate 200 in 100.The upper end opening of cabinet 100 is high-temperature gas air inlet 10, and the lower ending opening of cabinet 100 is height Warm gas outlet 20.Upper plate 110 has been fixedly installed in the lower end level of high-temperature gas air inlet 10, high-temperature gas gas outlet Lower plate 120 has been fixedly installed in upper end level.It is solid vertically in the space that cabinet 100 encloses between upper plate 110 and lower plate 120 Several heat dissipation plates 200 are determined.In the present embodiment, the upper end of heat dissipation plate 200 is welded on the upper surface of upper plate 110, The lower end of heat dissipation plate 200 is by expanding tense machine swelling in lower plate 120.Specifically, cross-sectional shape and the heat dissipation of expanding tense machine Plate is the same.And expanding tense machine can be embedded in heat dissipation 200 lower end of plate, and the outer end face of expanding tense machine and the interior of plate 200 that radiate End face fitting.It draws or pushes away by the plug at expanding tense machine center, so that heat dissipation 200 lower end of plate expands, finally make heat sink Plate hole swelling on piece 200 and lower plate 120.

Cryogenic gas gas outlet 30 and cryogenic gas air inlet 40 are provided on the left side wall 130 of cabinet 100.It is wherein low The top of left side wall 130 is arranged in warm gas outlet 30, and the lower part of left side wall 130 is arranged in cryogenic gas air inlet 40.

In this way, upper plate 110, heat dissipation plate 200, lower plate 120 form high temperature gas passage, it is cryogenic gas air inlet 40, low The space that warm gas outlet 30 and cabinet 100 enclose forms cryogenic gas channel.

In the present embodiment, heat dissipation plate 200 is that steel pipe is pressed into special-shaped plate, that is, chapped pipe.

In order to understand that the heat-exchangers of the plate type in the present embodiment, high-temperature gas and cryogenic gas introduced below flow over Journey:

High-temperature gas reaches the upper surface of upper plate 110 by high-temperature gas air inlet 10.Upper plate 110 prevents High Temperature Gas Body enters the inner space of cabinet 100, and can only be by arriving inside the special-shaped pipeline of the heat dissipation plate 200 welded with upper plate 110 It is flowed out up to high-temperature gas gas outlet 20, and by high-temperature gas gas outlet 20.Cryogenic gas enters by cryogenic gas air inlet 40 The inner space of cabinet 100, and in the pipeline lateral surface flowing of heat dissipation plate 200, finally flowed by cryogenic gas gas outlet 30 Out.

It in this embodiment, is negative pressure, institute at high-temperature gas gas outlet 20 since the inner space of cabinet 100 is positive pressure The inner space of cabinet 100 will not be entered with high-temperature gas.Meanwhile after 200 swelling of plate of radiating, between lower plate 120 Gap is very small, and heat dissipation plate 200 and lower plate 120 fit closely, and the air leakage phenomena after cryogenic gas is heated is negligible.

See that Fig. 3, Fig. 3 are the enlarged structure schematic diagram at the preferred embodiment of the utility model heat-exchangers of the plate type A again.It dissipates The medial surface insertion of the lower end of hot plate piece 200 and the expanding tense machine of the heat dissipation consistent polymorphic structure of sheet form.Pass through expanding tense machine Expansion so that the internal diameter of heat dissipation plate 200 is extended, and then swelling is on the through-hole of lower plate 120.In this way, in heat dissipation plate When 200 expanded by heating, the end of heat dissipation plate 200 be can break through under the frictional force stretching between heat dissipation plate 200 and lower plate 120 Plate 120.When the plate 200 that radiates is cooling, and original position can be contracted to.In this way, while guaranteeing to radiate 200 free extension of plate, Avoid the service life for deforming and influencing radiator caused by solid plate piece both ends are welded.

It is distributed in conjunction with the heat dissipation plate that Fig. 4 and Fig. 5, Fig. 4 are the preferred embodiment of the utility model heat-exchangers of the plate type Structural schematic diagram.Fig. 5 is the enlarged structure schematic diagram at the preferred embodiment of the utility model heat-exchangers of the plate type B.Overlook case Body 100 can see that the upper end of heat dissipation plate 200 is fixed on upper plate 110 from high-temperature gas air inlet 10, and heat sink The cross section of piece 200 is abnormity.The upper end of heat dissipation plate 200 is just passed through upper plate 110 without stretching out.

Specifically, the cross section of heat dissipation plate 200 is made of four sections of arcs, respectively upper radian 210, right radian 220, lower arc Degree 230 and left radian 240.Transversely medium line is symmetrical with lower radian 230 for upper radian 210, left radian 240 and right 220 edge of radian Vertical medium line is symmetrical, and the opening of upper radian 210 and lower radian 230 is greater than the opening of left radian 240 and right radian 220, on Radian 210, right radian 220, lower radian 230, left radian 240 end be sequentially connected end to end.

In other embodiments, cryogenic gas air inlet 40 and cryogenic gas gas outlet 30 can be set in cabinet 100 Two different side end faces on.

A kind of heat-exchangers of the plate type provided by the utility model makes to radiate 200 swelling of plate under by special expanding tense machine On plate 120, allow every piece of heat dissipation plate 200 flexible freely at swelling end in expanded by heating, and because of the interior of cabinet 100 Portion space is positive pressure, is negative pressure at high-temperature gas gas outlet 20, so the inside that high-temperature gas will not enter cabinet 100 is empty Between.Meanwhile radiate 200 swelling of plate after, the gap between lower plate 120 is very small, cryogenic gas be heated after leak out Phenomenon is negligible, so swelling end is essentially identical to closed state, and then substantially increases the service life of heat-exchangers of the plate type； Heat dissipation plate 200 is that steel pipe is pressed into special-shaped plate, and welding procedure is not present in side end face, and the possibility of desoldering is also just not present, Further improve the service life of heat-exchangers of the plate type；The cross section of special-shaped plate has upper radian 210, lower radian 230, left arc Degree 240 and right radian 220, transversely medium line is symmetrical with lower radian 230 for upper radian 210, left radian 240 and right 220 edge of radian Vertical medium line is symmetrical, and the opening of upper radian 210 and lower radian 230 is greater than the opening of left radian 240 and right radian 220, on Radian 210, right radian 220, lower radian 230, left radian 240 end be sequentially connected end to end, and then reduce windage, improve gas Perturbing property improves the heat transfer efficiency of heat exchange, so that heat dissipation plate 200 is uniformly heated.

It should be noted last that the above specific embodiment is only to illustrate the technical solution of the utility model rather than limits System, although the utility model is described in detail referring to example, those skilled in the art should understand that, it can be right The technical solution of the utility model is modified or replaced equivalently, without departing from the spirit and model of technical solutions of the utility model It encloses, should all cover in the scope of the claims of the utility model.
