Abstract
The utility model discloses a heat exchange plate for a plate type heat interchanger, belonging to a component for a heat interchange device whose heat exchanging mediums are not in direct contact, in particular to a fixing plate for two heat exchanging mediums, or a component for a heat exchanging device for a laminated passage, whose mediums are in contact with different sides of the passage. The heat exchange plate comprises a locating hole, a medium incoming and outgoing entrance, an incoming and outgoing entrance flow guide zone, a distributary zone and a heat transmitting zone, which is characterized in that: the plate ripples in the heat transmitting zone are divided along the center line of the plate into two sides; the obtuse angle ripples on one side are connected with the sharp angle ripples on another side. The beneficial effect of the utility model is in that: due to adopting different angle ripples along the center line of the plate, the flow rate of the heat exchange flux is in a right match with the permissible pressure drop. Meanwhile the diameter ratios of the ripple flow passages at the two sides of the heat exchange plate are different, enabling the flowing speeds of the cold and hot mediums between the plates are close or equal with each other, improving the heat exchange factor by 5 to 10 percent. The utility model is suitable for the manufacturer in this line to replace the prior art with the novel utility model.
Description
Technical field
The utility model belongs to the not direct parts of heat-exchange apparatus of contact of heat exchange medium, especially for the fixed head of two kinds of exchange medias or the heat-exchange apparatus of lamination passage, the parts of the heat-exchange apparatus of the contacts side surfaces that each medium is different with passage.
Background technology
Plate type heat exchanger is to be the high-efficiency heat exchanger equipment of heat transfer element with the metal corrugated plate, ripple employing symmetric design in its heat exchanger plates is that the angle of the ripple of same plate center line both sides is identical, though manufacture craft is simple like this, but the flow different needs of thermal medium and cold medium uses two kinds of plates of different angles to intersect assembling mutually to use under common heat exchange state, need the mould of usefulness many in the manufacturing, not easy to operate in the assembling.
The utility model content
The purpose of this utility model provides the technical scheme of a kind of angle of the ripple in heat transfer zone plate center line both sides New-type plate heat exchanging plate of heat exchanger inequality.
The technical solution of the utility model is, a kind of heat exchange plate for plate heat exchanger, comprise locating hole, medium import and export, import and export water conservancy diversion district, shunting zone, heat transfer zone, it is characterized in that: the plate ripple is divided into both sides with the plate center line in the described heat transfer zone, and a side is that the obtuse angle ripple is connected with the acute angle ripple of opposite side.
Described obtuse angle ripple is 100-130 °, and described acute angle ripple is 50-80 °.Optimize the obtuse angle ripple be 120 °, described acute angle ripple is 60 °.
Added reinforcement one between described two ripples.
Four angles of described heat exchanger plates are provided with the angle locking plate.
The corrugated channel latus rectum ratio on described heat exchanger plates two sides is 1: 1.5-1: 2.5.Optimize the corrugated channel latus rectum ratio on heat exchanger plates two sides be 1: 2.2.
The beneficial effects of the utility model are because the plate ripple is divided into both sides with the plate center line, and the obtuse angle ripple that a side is 120 ° connects the acute angle ripple of 60 ° of opposite sides; Thereby play the resistance difference that furthers between different runners and reach the principle that heat is mixed, can accomplish the coupling fully between heat exchange amount flow and allowable pressure drop, can save heat exchange area greatly.At 120 ° obtuse angle corrugated regions, added one reinforcement between two ripples, avoided also having increased the strength and stiffness of plate simultaneously because left and right sides corrugated stretch difference causes the generation of plate metaboly, improved the bearing capacity of heat exchanger.Four angles of heat exchanger plates are provided with the angle locking plate, can improve positioning accuracy.The corrugated channel latus rectum ratio on heat exchanger plates two sides is 1: 2.2; The cold rate-of flow specific heat of most of heat supply occasions rate-of flow is big, allow the cold medium of big flow walk wide runner, allow the low discharge thermal medium walk narrow runner under the situation of single process, can make the flow velocity of cold and hot medium between plate approaching or equal, can improve the exchange capability of heat of plate type heat exchanger like this, promptly improve the coefficient of heat transfer.Under the situation that cold and hot media processes amount does not wait, select for use the unequal section plate type heat exchanger can reduce certain device and select area for use, can reduce the equipment component investment.The heat exchanger coefficient of heat transfer of the original plate assembling in plate type heat exchanger angle of the disclosed heat exchanger plates assembling of the utility model can improve 5-10% according to surveying and determination.The utility model has only changed the bellows-shaped of heat transfer zone in the heat exchange plate, and original production enterprise only need change mould just can realize model change.
