Abstract

The utility model relates to an indirect evaporating cooling type plastic plate shape heat exchanger, belonging to a heat exchanging apparatus for an air conditioner cooling. The utility model is characterized in that the heat exchanger fins of evenly distributed protrusions which are distributed on a surface are formed into a parallelogram. The short sides of each parallelogram are perpendicular to a horizontal line, and the long sides of each parallelogram and a horizontal line are formed into an incline angle of from 15 DEG to 25 DEG. The shapes of the longitudinal sections of the long and the short sides between the neighboring fins can be interchanged. The protrusions are formed into wave shapes and are provided with wedge-shaped articles at a wave trough point, and the protrusions can be formed into wedge-shaped protrusions which are arranged on a plate surface. The wave-shaped protrusion between the neighboring fins is in phase or in reversed phase. The utility model has the advantages of flow speed reduction, frictional force reduction, humidity increase, etc., for a secondary air. Simultaneously, the height of the equipment can be lowered under the condition of having same heat exchanger fins.

Description

Indirect evaporating cooling type plastic plate shape heat exchanger

A kind of indirect evaporation cooled plastic plate type heat exchanger belongs to the heat-exchange apparatus field of air-conditioning refrigerating.

Indirect evaporation cooled plastic plate type heat exchanger is the frame-type heat exchanger that a kind of upper/lower terminal is compressed the heat exchanger fin fuse by a metal framework and along the upper and lower limit of framework the heat exchanger fin fuse of uniform thrust on the plate face and metal frame glued mutually, its heat exchanger fin is generally rectangular, under identical cross-directional length secondary general mood circulation road can't be prolonged again with reach reduction of speed, the power of reducing friction, humidification and the purpose that reduces device height.

The purpose of this utility model is to provide a kind of and regularly not only can have made secondary wind reduction of speed humidification but also can reduce the indirect evaporation cooled plastic plate type heat exchanger of device height under a certain wind passage when heat exchanger fin area one.

Of the present utility model being characterised in that: the heat exchanger fin parallelogram of uniform thrust on the face, its minor face are perpendicular to horizontal line, and its long limit becomes 15～25 degree top rades with horizontal line, and the shape in the vertical section on the long and short limit between the adjacent both sides is exchanged.Its thrust is corrugated, and there is wedge at the place at trough; Corrugated projection between adjacent two heat exchanger fins can be parallel to each other also can differ 180 degree angles.Above-mentioned thrust also can be the wedge-like projection on the plate face.

In order in conjunction with the embodiments the utility model to be done more detailed describing below, now as follows employed accompanying drawing title of present specification and numbering brief introduction:

Fig. 1. the vertical view 1 of heat exchanger fin;

Fig. 2. the profilograph of above-mentioned heat exchanger fin;

Fig. 3. the vertical view 2 of heat exchanger fin;

Fig. 4. the profilograph of heat exchanger fin among above-mentioned Fig. 3;

Fig. 5. the corrugated protrusions thing is the profilograph after adjacent two connections when paralleling;

Fig. 6. the profilograph when the corrugated protrusions thing differs 180 degree angles after adjacent two connections;

Fig. 7. the heat exchanger fin profilograph of wedge-shaped protection on the plate face.

Embodiment

Ask for an interview Fig. 1～7.Fig. 1, Fig. 3 are that the vertical section shape on its long and short limit is different but be the vertical view of interchangeable two adjacent heat exchanger fins, and Fig. 2, Fig. 4 are the profilographs corresponding with them.Wherein, the 1st, corrugated projection or depression, the 2nd, be positioned at the wedge at trough place, 3,4 is respectively different but two heat exchanger fins that promptly can exchange of long and short limit vertical sectional shape, but its corrugated protrusions thing all is identical.Fig. 5～6 expression is parallel to each other and differs annexation between 180 the limits when spending angles when the corrugated protrusions thing of adjacent two heat exchanger fins is respectively.It on Fig. 7 display plate face the heat exchanger fin profilograph of wedge-like thrust 5.

Because the heat exchanger fin surface has just been strengthened the wind air quantity one time in that the air communication mistake that is 19 degree angles with vertical line is vertically arranged.laterally have with horizontal line also be 19 degree top rades and with long limit parallel gas flow passage, secondary wind is just had the flow velocity of reduction, the power of reducing friction, increases the cooling water contact probability is advantages such as humidification, and when one timing of heat exchanger fin area, also can correspondingly reduce the height of heat exchanger fin, also just reduce device height simultaneously.In addition, the interchangeability of the vertical section shape on long and short limit also provides convenience for processing, connection between adjacent two.As for the shape of thrust then can according to reality as for the knuckle at heat exchanger fin diagonal two ends among the figure when adorning metal frame so that processing and heat seal.

Claims
