Abstract
The utility model relates to a novel corrugated heat exchanging sheet for a plate exchanger. Two contiguous corrugations on the heat exchanging sheet of the utility model share one wave hollow, and the height of one wave crest is one-third to two-third of that of the other wave crest. The wave hollow that shared by the two contiguous corrugations on the heat exchanging sheet is a short plane; the top of the higher wave crest is a short plane, and the top of the lower wave crest can be a circular arc face, a short plane or other smooth transitional surfaces. The heat exchanging sheets adopting the structure are overlapped layer by layer in a staggered mode to form the plate exchanger, wherein one of the cross section areas of two working substance flow channels is 1.2 to 1.6 times of the other cross section area, the high-temperature working substance flows through the flow channel whose cross section area is small, and the low-temperature working substance flows through the flow channel whose cross section area is big; thus, the flow speeds of the two working substances are different, and the heat exchanging efficiency can be enhanced greatly, wherein the temperature variation delta of the high-temperature working substance can achieve 20 DEG C, and the temperature variation delta of the low-temperature working substance can achieve 40 DEG C.
Description
Technical field
The utility model relates to the novel ripple heat exchanger fin that a kind of plate type heat exchanger is used.
Background technology
Plate type heat exchanger has a very wide range of applications at refrigerating field, and one of them vitals is exactly a heat exchanger fin.In the prior art, the ripple struction of common heat exchanger fin is equally sizes of adjacent two ripples, and all row are arranged, and such structure fabrication is very convenient, and working medium is flowed through the sectional area size too, and heat exchange efficiency is difficult to improve a lot; A kind of ripple struction of heat exchanger fin of improved, adjacent two ripples are still equally big or small, just increase fin structure at corrugated surface, can improve heat exchange efficiency to a certain degree like this, but manufacture difficulty also increases a lot, production cost is too high, has also restricted the applying of heat exchanger fin of this structure.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the novel ripple heat exchanger fin that the utility model provides a kind of plate type heat exchanger to use.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the novel ripple heat exchanger fin that a kind of plate type heat exchanger is used, the shared trough of adjacent two ripples on the described heat exchanger fin, the one crest height is the 1/3-2/3 of another crest height.The shared trough of adjacent two ripples is a short plane on the heat exchanger fin; The top of higher crest is a short plane, and the top of low crest is to be arc surface, can perhaps be other smooth excessiveness faces for short plane also.
Adopt the heat exchanger fin of said structure, one positive one is anti-superimposed layer by layer, the plate type heat exchanger that constitutes, wherein one of the sectional area of two kinds of working medium runners be another 1.2-1.6 doubly, the high temperature refrigerant long-pending runner of small bore of flowing through, the cryogenic fluid long-pending runner in heavy in section of flowing through, the flow velocity of such two kinds of working medium is also just different, heat exchanger effectiveness can improve a lot, and the variations in temperature Δ t of its middle and high temperature refrigerant can reach 20 ℃, and the variations in temperature Δ t of cryogenic fluid can reach 40 ℃.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, the shared trough 6 of adjacent two ripples on first heat exchanger fin 1, one crest 7 highly are the 1/3-2/3 of another crest 5 height, are traditionally arranged to be a crest 7 and highly are 1/2 of another crest 5 height.The shared trough 6 of adjacent two ripples is a short plane on first heat exchanger fin 1; The top of higher crest 5 is a short plane, and the top of low crest 7 also is a short plane, and arc surface or other smooth excessiveness faces also can be arranged in the top of low crest 7 certainly.
The structure of second heat exchanger fin 2 and first heat exchanger fin be symmetry about in the of 1; The 3rd heat exchanger fin 3 is the same with first heat exchanger fin, 1 structure, and the structure of the 4th heat exchanger fin 4 and the 3rd heat exchanger fin be symmetry about in the of 3; And the like.
Such one positive one anti-heat exchanger fin is the plate type heat exchanger of superimposed formation layer by layer, wherein the sectional area size of two kinds of working medium runners is different, referring to Fig. 1, shade A is the long-pending runner of small bore among the figure, shade B is the long-pending runner in heavy in section, B=1.2-1.6A generally speaking, the high temperature refrigerant long-pending runner of small bore of flowing through, the cryogenic fluid long-pending runner in heavy in section of flowing through, the flow velocity of such two kinds of working medium is also just different, heat exchanger effectiveness can improve a lot, and the variations in temperature Δ t of its middle and high temperature refrigerant can reach 20 ℃, and the variations in temperature Δ t of cryogenic fluid can reach 40 ℃.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every foundation technical spirit of the present utility model all should be thought to belong to protection domain of the present utility model to any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. the novel ripple heat exchanger fin that plate type heat exchanger is used is characterized in that the shared trough of adjacent two ripples on the described heat exchanger fin, and the one crest height is the 1/3-2/3 of another crest height.
2. the novel ripple heat exchanger fin that plate type heat exchanger according to claim 1 is used is characterized in that the shared trough of adjacent two ripples is a short plane on the described heat exchanger fin; The top of higher crest is a short plane, and the top of low crest is to be arc surface, can perhaps be other smooth excessiveness faces for short plane also.
