Abstract
The utility model relates to a heat-exchanging plate sheet and particularly relates to a heat-exchanging plate sheet of a plate type heat exchanger. A plate sheet is provided with a plurality of concave parts; the upper and lower bottom surfaces of the concave parts are circular; and the section of a concave shaft is in an isosceles trapezoid shape. The heat-exchanging plate sheet has the advantages of strong heat exchanging effect and small pressure drop; and under the condition of water-water heat exchange, the total heat transferring coefficient is 2-3 times that of a pipe shell type heat exchanger under the same condition and is 1.5 times that of a spiral plate type heat exchanger.
Description
Technical field
The utility model relates to a kind of heat exchange plate, particularly relates to a kind of heat exchange plate for plate heat exchanger sheet.
Background technology
The plate of plate type heat exchanger is the thin plate of being made by various materials, is pressed into different ripple with grinding tool on the thin plate, and has the hole, angle at four angles of plate, is used for the circulation of medium.And the shape and structure of ripple directly determines resistance and the heat exchange area of medium between plate.
The plate of traditional plate type heat exchanger is generally herringbone, is easy to form the dead band, affects heat transfer effect.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of heat exchange plate for plate heat exchanger sheet, its can be under lower Reynolds number just can turbulization, thereby improve heat transfer effect.
The technical solution of the utility model is as follows:
A kind of heat exchange plate for plate heat exchanger sheet, its special feature be, described plate is provided with some depressions, and it is circular that the upper bottom surface of described depression is respectively, and the depression shaft section is isosceles trapezoid.
Preferably, the bottom surface of described depression and the angle of side are 45 °, and the diameter of described bottom surface is 10mm, and the distance between upper bottom surface and the bottom surface is 1.5mm.
The utility model is provided with depression at plate, has strengthened heat exchange area, and when flow during through plate because this design of depression, just can turbulization under lower Reynolds number, thus improved the effect of heat exchange.Adopt the heat exchanger of this kind plate, heat transfer effect is strong, and pressure drop is little, under the operating mode of water-water heat exchange, the 2-3 that overall heat-transfer coefficient is equivalent to shell-and-tube heat exchanger under the equal operating mode doubly, 1.5 times of spiral heat exchanger.
Description of drawings
Fig. 1 is the structural representation of plate.
Fig. 2 is the shaft section structural representation of depression.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of heat exchange plate for plate heat exchanger sheet, described plate is provided with some depressions 1, it is circular that upper bottom surface 2 bottom surfaces 3 of described depression 1 are respectively, the depression shaft section is isosceles trapezoid, the bottom surface of described depression and the angle of side 4 are 45 °, the diameter of described bottom surface is 10mm, and the distance between upper bottom surface and the bottom surface is 1.5mm.
Claims (2)
