Above-mentioned plate type heat exchanger can not be used in the high-pressure medium heat-exchange system of more than 25 kilograms, because under the environment of high pressure, rubber seal exists seal failure, easily leaks water problem.
Utility model content
Can not be applicable to the high pressure heat exchange intersystem problem of 25 kilograms and above pressure to solve existing plate type heat exchanger, the purpose of this utility model is to provide a kind of high-pressure plate type heat exchanger.
The utility model solves the technical scheme that its technical problem adopts:
A kind of high-pressure plate type heat exchanger, comprise framework and plate assembly, its middle frame is made up of fixed pressure plate, movable pressure plate, upper lower guide rod and fishbolt, it is characterized in that, described plate assembly is one of following two kinds of patterns:
A: be welded to connect formation heat exchange unit along medium holes and edge between two panels plate, then use sealing gasket to be connected and sealed the edge between some heat exchange units and form plate assembly, walk high-pressure medium inside described heat exchange unit, low-pressure medium is walked in outside;
B: be welded to one another the complete plate assembly of formation one along medium holes and edge between multiple plate;
Described plate in two kinds of patterns is metal stamping plate, and is formed with the concave convex texture being beneficial to moisture film and being formed at the outer surface of described heat exchange unit, four angles of described plate have for cold medium and thermal medium into and out of medium holes.
Further, the concave convex texture (medium channel) on described plate is lambdoid lines, and the medium channel of same plate both sides is intersected with each other.
Further, described plate is the one in stainless sheet steel, copper alloy thin plate, aluminium alloy sheet.
Further, described plate profile is the one in square, rectangle, polygon, circle.
The beneficial effects of the utility model are: the utility model discloses a kind of welded plate-type heat-exchange assembly, sealed by original rubber gasket, be designed to integrally welded structure, simplify the installation process of heat-exchanging component.Meanwhile, due to the medium of certain pressure can be born, add entropy, improve cooling effectiveness.Meanwhile, overall or local adopts welding procedure to substitute original sealing gasket and seals, and compressive resistance is high, can meet the use of the high-pressure medium of more than 2.5MPa (25 kilograms).
Accompanying drawing explanation
Fig. 1 is the structure chart of plate in existing plate type heat exchanger.
Fig. 2 is the structure chart of plate in the high-pressure plate type heat exchanger improved.
Fig. 3 is schematic diagram of the present utility model.
Fig. 4 is the heat exchange principle figure of plate type heat exchanger.
In figure: 1 plate, 11 medium holes, 12 are welded to connect, 2 rubber gaskets, 1 ' plate, 11 ' corner apertures.
Detailed description of the invention
Existing plate type heat exchanger completely cuts off owing to using rubber gasket to carry out sealing between each plate, so operating pressure is unsuitable excessive, medium temperature is unsuitable too high, otherwise likely reveal, operating pressure is generally no more than 1.5MPa, medium temperature lower than less than 250 DEG C, otherwise likely should be revealed.
For this problem; key point of the present utility model and protection point are to have changed the combining form between adjacent plate and seal form; adopt the mode of welding to substitute original sealing structure of pad type, the high-pressure plate type heat exchanger after improvement may be used for the heat exchange occasion of 2.5MPa and above medium.
Comprise framework and plate assembly, its middle frame, be made up of fixed pressure plate, movable pressure plate, upper lower guide rod and fishbolt etc., for the fixing of plate assembly and protection.
As shown in Figure 2 to Figure 3, plate 1, different ripple is pressed into various multi-form grinding tool by the thin plate made of various material, form medium flow channels, and medium holes 11 (corner apertures) is had on four angles of plate, for the turnover of cold medium and thermal medium, as shown in Figure 2, with the channel design of the medium in existing plate type heat exchanger, corrugated form is identical, difference is, boundary (comprising plate edge and medium holes position) along each medium channel carries out being welded to connect 12, form weld seam (dashed path in Fig. 2), become a heat exchange unit module, in fig. 2, path along original sealing gasket 2 is welded, namely original sealing gasket sealing means is substituted, form a kind of permanent existence form.
There are two kinds of patterns in above-mentioned welding:
Pattern one, be welded to connect between two plates 1 and form one, form a heat exchange unit, can combinationally use, then use sealing gasket to be connected and sealed by between the heat exchange unit of welding, form welding, sealing gasket sealing intersects the pattern carrying out arranging, and forms the heat exchange pattern of low pressure side, side high pressure like this, wherein walk high-pressure medium inside heat exchange unit, low-pressure medium is walked in outside.
Pattern two, is welded to one another the plate assembly that formation one is complete between above-mentioned multiple plates, as shown in Figure 3, form the heat exchange pattern that high-pressure medium is walked in both sides like this, form cold medium entrance A, cold media outlet B, thermal medium inlet C and thermal medium outlet D.Because plate adopts stainless steel welded sealing, be compared to the sealing of rubber cushion, the stainless steel welded pressure that can bear is larger.
Concave convex texture design on above-mentioned heat exchange plate 1 can be the design of lambdoid lines, and this time intersects, and forms support each other, the situation that can not deform.
Be intervally installed between the medium channel of above-mentioned same plate both sides, form the transfer path intersected, and be the PROCESS FOR TREATMENT connecing technique or be combined with sealing strip between corresponding two metallic plates each other.
Above-mentioned plate adopts stainless sheet steel punching press to be formed, and forms some chevron shaped channels of continuously, to intersect, i.e. medium channel to be cooled and hot media channel in both sides, and the sealing gasket place of two metallic plates is carried out pressure welding and form one.
In above-mentioned introduction, also can adopt alloy sheets for the plate making heat exchange unit, such as copper alloy thin plate, aluminium alloy sheet etc. carry out punching press making, meet thin-walled, light weight, feature corrosion-resistant, easy to clean.
The pattern of the medium channel between above-mentioned plate is various, can use for reference the relevant lines design in the plate in existing plate-type heat-exchange assembly, all be applicable to the utility model.
Above-mentioned heat exchanger can single, many rows, serial connection, the various ways such as arranged side by side be arranged, all within protection domain of the present utility model in cooling tower.
Embodiment recited above is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in protection domain as determined in the utility model claims.
