Fig. 2 is the viewgraph of cross-section as two orifice passages of the part of transversal plate type heat exchanger of the present invention.
Fig. 3 represents the front view of the part of external heat transfer plate, and this external heat transfer plate is the part as the plate type heat exchanger of Fig. 2.
Fig. 4 is the viewgraph of cross-section of two orifice passages of the plate type heat exchanger of transversal an alternative embodiment of the invention.
The specific embodiment
The part of the plate type heat exchanger of the clear expression of Fig. 1 prior art, this heat exchanger comprise planar end plate 1, one external heat transfer plate 2a and two internal heat transfer plate 2b and 2c, and plate 2a is identical with 2c and be same type, and plate 2b is another kind of type.Usually, use a plurality of heat transfer plates and an end plate.Obviously also have for two kinds of two passages 3,4 that heat exchanging fluid is used among the figure, be appreciated that thus these fluids also need two other passage.
Each heat transfer plate is pressed into zone on every side, the most close aperture respectively in Different Plane.Like this,, be positioned at a lower plane, go up the plane and be positioned at one as the zone in the most close aperture of the part of passage 4 as the zone around the most close aperture of the part of passage 3 for external heat transfer plate 2a.When the plate core was connected with planar end plate 1, this can produce some problems.According to prior art, seal washer/shading ring 5 is used for the distance between crossover passage 3 inside and outside heat transfer plates and the end plate.
The clear expression of Fig. 2 is according to the part of plate type heat exchanger of the present invention, and this heat exchanger comprises 11, one external heat transfer plates of planar end plate 12a (seeing Fig. 3 in addition) and two internal heat transfer plate 12b and 12c, and all these plates can be different types.Usually, also use more heat transfer plate and another end plate here.Shown two passages 13,14 that use for two kinds of heat exchanging fluids among the figure, but also needed two other passage for these fluids by the plate core.
External heat transfer plate 12a is different with internal heat transfer plate 12c.Externally being used between heat transfer plate 12a and the end plate 11 zone carrying and seal the aperture around and near, at least three and preferably all aperture are in same plane.Accomplish that this point is possible, do not need differently to suppress heat transfer plate at position 12a and position 12c and handle this plate for use.Around at least one and preferably in the Different Plane in each critical aperture, described plate simply is provided with two concentric seal areas, and critical aperture is meant in this position, aperture, pays the utmost attention to the plane of the seal area that the operating position with plate changes.In operation subsequently, punching or cut out the aperture onboard.(in fact, can consider conversely the order of operating procedure, that is, and punching or cutting before pressboard).
By changing the size of cutting hole, also can change the position on the plane of seal area.If the hole of the diameter C among Fig. 2 is for example provided in cutting in a plate, then in lower plane, obtain the aperture of passage 13, and this plate is applicable among the 12c of position and (perhaps is applicable among the position 12a that is provided with seal washer or analog).But, if it is A-then the aperture of passage 13 is set in last plane that plate cuts out a less hole-diameter, this plane directly is connected with end plate 11 like this, and does not need to use any seal washer or analog, and this plate is directly applied among the 12a of position.
Fig. 4 clearly represents two end plates 21 and 22, two external heat transfer plate 22a and 22d, and the position relation of two internal heat transfer plate 22b and 22c.The quantity of internal heat transfer plate is bigger usually.After compacting, external heat transfer plate 22a is identical with internal heat transfer plate 22c-owing to the aperture of the different size of cutting channel 23 in each plate produces difference.After compacting, internal heat transfer plate 22b is also identical with external heat transfer plate 22d-since in each plate the aperture of the different size of cutting channel 23, also produce difference in this case.Because conditions of similarity appears in other end of plate core, therefore externally in the heat transfer plate all seal areas around the aperture meet very much each end plate.(and, in this connection, can opposite order operate.)
If desired, the heat transfer plate that has the 12c in already present aperture or a 22c type is convertible into the heat transfer plate (without any need for seal washer or analog) of 12a or 22a type later on.In a similar fashion, the heat transfer plate that has a 22b type in already present aperture is convertible into the heat transfer plate of 22d type later on.By simply the orifice edge of passage 13,23 being risen to the height identical with the aperture of passage 14,24, finally like this make seal area be positioned at same level, thereby realize above-mentioned conversion.The edge promotes can take any known suitable mode to carry out, for example with transfer tool or similar tool.
Externally the aperture in the heat transfer plate can be of different sizes.The most general situation is four passages that utilize two kinds of heat exchanging fluids probably and pass the plate core, and externally can there be and has same size in pairs in the aperture in the heat transfer plate.In this case, after plate type heat exchanger was assembled together, each in two apertures in each external heat transfer plate still can be centered on by two concentric seal areas, as a result one of them seal area along circumferential arrangement another the outside.
No matter make what type, each in all heat transfer plates can be made into the flange shape marginal portion of the whole circumference with winding board, and the principal plane of this marginal portion and plate extension and is carried on respective edges part on the adjacent panels of plate in-core at an angle.On the mutual load-bearing surface of plate in-core, nearest described flange shape marginal portion for example, can be for example by soldering tightly liquid connect airtight and close.
Plate is made by sheet metal usually, but can also adopt for example titanium of other material.
The present invention is not subject to form described here, can not break away from spirit of the present invention and change.
