Abstract

The utility model discloses an efficient heat exchange plate sheet, which is provided with a positioning hole, a medium inlet and outlet, a flow guide zone, a flow splitting zone and a heat transfer zone. The flow splitting zone is in an isosceles triangle shape, and a plurality of diamond protruded blocks are arranged in the flow splitting zone and divide the flow splitting zone into a plurality of flow splitting grooves parallel to waists of the triangle. By means of the efficient heat exchange plate sheet, heat exchange media can be evenly distributed to the heat transfer zone, flow resistance of the media is small, and heat exchange efficiency is high.

Description

A kind of high efficient heat exchanging plate

Technical field

The utility model relates to a kind of parts of heat exchanger, especially a kind of heat exchange plate of plate type heat exchanger.

Background technology

Heat exchange plate is a heat exchanger components important in the plate type heat exchanger, and the shape of heat exchange plate and structure will directly influence the heat exchange effect of heat exchanger, be typically provided with shunting zone and heat transfer zone on the heat exchange plate; Shunting zone is being born the task of heat transferring medium being assigned to heat transfer zone; If the shunting zone design is unreasonable, will make dielectric distribution inhomogeneous, cause heat transfer zone bias current, the uneven phenomenon of heat conduction to occur; Cause heat transfer efficiency to reduce, resistance drop strengthens.

The utility model content

The technical problem that utility model will solve is: a kind of high efficient heat exchanging plate is provided, and this heat exchange plate makes heat transferring medium be assigned to heat transfer zone equably, and the media flow resistance is little, heat exchange efficiency is high.

The technical scheme that the technical solution problem is adopted: a kind of high efficient heat exchanging plate; On heat exchange plate, be provided with locating hole, medium import and export, water conservancy diversion district, shunting zone and heat transfer zone; Said shunting zone is an isosceles triangle; Be provided with a plurality of rhombus projections at shunting zone, the rhombus projection is divided into many splitter boxs parallel with leg-of-mutton waist with shunting zone.

Improvement as the utility model: be provided with in the splitter box below the medium of a side is imported and exported and press down the stream piece, the said stream piece that presses down is for connecting the convexity of splitter box both sides rhombus projection, and the height that presses down the stream piece is lower than the height of rhombus projection.

Further improvement as the utility model: it is a plurality of pressing down the stream piece, and a plurality of stream piece equidistance that press down are arranged in the splitter box.

Beneficial effect: in the utility model, on heat exchange plate, be provided with locating hole, medium import and export, water conservancy diversion district, shunting zone and heat transfer zone owing to having adopted; Said shunting zone is an isosceles triangle, is provided with a plurality of rhombus projections at shunting zone, and the rhombus projection is divided into shunting zone the technical scheme of many splitter boxs parallel with leg-of-mutton waist; Make fluid be evenly distributed in the various piece of shunting zone; Reduced the resistance of fluid, made the minimise loss of pressure of shunting zone, made all physical area of plate all be converted into the effective heat exchange area; Heat exchange efficiency has been improved in no heat exchange dead band; Owing to adopted to be provided with in the splitter box below the medium of a side is imported and exported and pressed down the stream piece; The said stream piece that presses down is for connecting the convexity of splitter box both sides rhombus projection; The height that presses down the stream piece is lower than the technical characterictic of the height of rhombus projection; Overcome each splitter box because the resistance difference that the length difference causes makes the medium distribution more even, better effects if; To press down the stream piece be a plurality of owing to adopted, a plurality of stream piece equidistance that press down are arranged on the technical characterictic in the splitter box, further improved the uniformity coefficient that medium is assigned to heat transfer zone, makes the heat exchange efficiency of the plate type heat exchanger that the heat exchange plate that adopts the utility model processes higher.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Fig. 1 is the structural representation of the heat exchange plate of the utility model, has omitted the symmetrical other end.

The specific embodiment

As shown in Figure 1, the high efficient heat exchanging plate of the utility model is provided with locating hole 1, medium import and export 3, water conservancy diversion district 4, shunting zone 2 and heat transfer zone 7 on heat exchange plate; Said shunting zone is an isosceles triangle, is provided with a plurality of rhombus projections 5 at shunting zone, and the rhombus projection is divided into many splitter boxs parallel with leg-of-mutton waist with shunting zone; Be provided with in the splitter box below the medium of a side is imported and exported and press down stream piece 6; The said stream piece that presses down is for connecting the convexity of splitter box both sides rhombus projection, and the height that presses down the stream piece is lower than the height of rhombus projection, for further uniform distribution medium to heat transfer zone; A plurality of stream pieces that press down are set in splitter box, and a plurality of stream piece equidistance that press down are arranged in the splitter box.
