Abstract
The utility model discloses a plate type heat exchanger with wide and narrow channels, comprising a channel flange connecting pipe (1), a wide channel flange connecting pipe (2), a fixing and clamping plate (3), a clamping bolt (4), a nut (5), an upper positioning transverse beam (6), a nut (7), a movable clamping plate (8), a bracket (9), a lower positioning transverse beam (nut) (10), the plate sheets (11) of A plates, and the plate sheets (12) of B plates. The ratio of the cross sectional area of a cold medium channel which is formed by two adjacent plate sheets (11) of the A plates and the plate sheets (12) of the B plates, and a heat medium channel which is formed by the plate sheets (12) of the B plates and the plate sheets (11) of the A plates is 3.5: 1. The plate type heat exchanger with wide and narrow channels has the advantages that the flow speed of a cold medium and a heat medium between plates can achieve to be approximate or equal, etc.
Description
The utility model relates to a kind of improvement technology of plate type heat exchanger.
Existing plate type heat exchanger is to be the high-performance heat exchanger of heat-transfer area with the corrugated plating.The plate type heat exchanger of producing both at home and abroad though various ways and specification are arranged, all equates with the formed cold and hot passage of a kind of plate of specification at present.The heat transfer coefficient that improves plate type heat exchanger just must make the flow velocity of these two kinds of fluids of cold and hot medium between plate approaching as far as possible or equal, if adopt present plate type heat exchanger such as passage such as grade, have only when the flow-rate ratio of hot and cold medium is 1:1, the flow velocity of hot and cold medium between plate just equates.Allowing the flow-rate ratio of hot and cold medium in the production technology at present in industrial production is 3.5:1.In order to improve the heat transfer efficiency of plate type heat exchanger, make the flow velocity of hot and cold medium between plate reach approaching or equal, foreign data proposes to solve the contradiction that this treating capacity does not wait with the way that changes path combination, be that the little medium of flow adopts multipaths, the medium that flow is big adopts single process, the shortcoming of this way is that flowing of hot and cold medium wants some following current to conduct heat, reduced the heat-transfer capability of heat exchanging fluid, its bigger shortcoming also is also tube connector must be arranged on the ambulatory splint, and this brings many inconvenience for the disassembly, cleaning of heat exchanger.
The purpose of this utility model is will provide a kind of hot and cold rate-of flow than being 3.5:1, and single process and hot and cold medium tube connector are at the plate type heat exchanger of clamping plate one side.
The utility model comprise the adapter of narrow passage flange, the adapter of fat pipe flange, fixed clamping plate, fishbolt, nut, on locate crossbeam, nut, active clamped plate, support, locate cross rail (nut), A plate plate, B plate plate down.Two adjacent A plate plates and the formed cold medium channel of B plate plate are 3.5:1 with the ratio of the cross-sectional area of B plate plate and the formed hot media channel of A plate plate.Its hot and cold medium tube connector is in a side of clamping plate, and medium adopts the form of single process diagonal angle adverse current, and hot and cold medium tube connector diameter ratio is 1:1-3:1.That the shape of the ripple of its plate can be is trapezoidal, circular arc, triangle.
The utlity model has when cold and hot media processes amount does not wait, using this equipment can make the flow velocity of hot and cold medium between plate reach approaching or equal, thereby improve the heat transfer coefficient of plate type heat exchanger, again because medium adopts the form of single process, tube connector can reduce the drag losses of equipment in clamping plate one side, and helps advantages such as the Installation and Debugging of equipment and maintenance.
Below in conjunction with description of drawings embodiment:
Fig. 1 is a width passage plate-type heat-exchange overall structure schematic diagram.
Learn from Fig. 1: this utility model comprises that the narrow passage flange takes over 1, the fat pipe flange takes over 2, fixed clamping plate 3, fishbolt 4, nut 5, locate crossbeam 6, nut 7, active clamped plate 8, support 9, locate crossbeam 10, A plate plate 11, B plate plate 12 down.During fabrication, the plate pull and stretch is finished by two cover cupping tools, i.e. A board mold and B board mold.A plate plate 11 is a fat pipe with the passage that B plate plate 12 forms, and B plate plate 12 is a narrow passage with the passage that A plate plate 11 forms.First plate is that 11, the second plates of A plate are B plate 12 during assembling, and A plate and B plate are arranged continuously, and last plate still is an A plate 11, all pastes gasket seal between every plate.Plate after arranging and finishing is seated ambulatory splint 8, is clamped to given size with fishbolt 4, nut 5 then.Making the ratio of the cross-sectional area of the adjacent two plates formation of heat exchanger is 3.5:1.In use, the medium that flow is little is taken over by upper left mouthful of flange and is flowed into, and is taken over by bottom right mouth flange to flow into again, and is taken over by bottom right mouth flange and flows out.
Claims (3)
1, a kind of width passage plate type heat exchanger comprise the narrow passage flange take over (1), fat pipe flange take over (2), fixed clamping plate (3), fishbolt (4), nut (5), on locate crossbeam (6), nut (7), active clamped plate (8), support (9), locate crossbeam (nut) (10), A plate plate (11), B plate plate (12) down, it is characterized in that the ratio of the cross-sectional area of two adjacent A plate plates (11) and the formed cold medium channel of B plate plate (12) and B plate plate (12) and the formed hot media channel of A plate plate (11) is 3.5: 1.
2, a kind of width passage plate type heat exchanger according to claim 1 is characterized in that the side of hot and cold tube connector at clamping plate (8), and hot and cold medium tube connector (1), (2) diameter ratio are 1:1-3:1.
3, root occupies the described width passage of claim 1 plate type heat exchanger, and that the shape that it is characterized in that the ripple of plate can be is trapezoidal, circular arc, triangle.
