Abstract

A plate heat exchanger with end surface being form-sealed is prepared as forming heat exchange plate by stacking passageway prepared with folded flat strip plates, forming seal at folded end surface naturally and only pressing two sides of heat exchange plate to be sealed with side strip, setting fluid inlet on two sides near to folding point and enabling to press heat exchange plate to be corrugated form as required.

Description

End face forming sealed heat-exchangers of the plate type

Technical field

The present invention relates to a kind of heat-exchangers of the plate type.

Background technology

The board-like plate fin type heat exchanger that comprises has advantages such as efficient height, relative volume be little, can extensive use at HVAC and industrial circle, but its manufacturing and sealing have limited its extensive application.For example be used for the traditional plate fin type heat exchanger of HVAC, consider from making the sealing angle, generally all the flat heat exchanger plates in the side of adopting and ripple corrugated sheet intersect placement at interval, and the gluing pressing seals, two fluid distributary heat exchanges.So not only there is the thermal contact resistance between heat exchanger plates and the corrugated sheet, and itself is again non-countercurrent flow, so that heat exchanger effectiveness is compared with the heat exchange area that it has is not high.Saying that its efficient height is because heat exchange area increases, is the efficient that cost improves to consume the heat exchange material.This traditional plate fin type heat exchanger adopts gluing pressing sealing in addition, in fact not only make inconvenience, and sealing is also unreliable.

Summary of the invention

It is higher to the purpose of this invention is to provide a kind of heat exchanger effectiveness, and better tightness is made easier heat-exchangers of the plate type simultaneously.

For achieving the above object, the technical solution used in the present invention is as follows: this heat-exchangers of the plate type mainly is made up of heat exchanger plates and side slat, close with some side slat sealed junctions the both sides of heat exchanger plates, it is characterized in that: described heat exchanger plates is to become with banded flat plate folding that the passageway is stacked to form, the both sides of heat exchanger plates or one-sidedly be provided with fluid flow port by bending part.Heat exchanger plates can suppress the various ripples that help augmentation of heat transfer in addition.

Heat exchanger plates material described in the scheme can be sensible heat exchange material and full heat exchange material, the sealing of described heat exchanger plates both sides is in conjunction with being various ways such as pressing sealing, bonding, welding, and the folding bending shape of described heat exchanger plates can be various ways such as the adjustable triangle of nonadjustable rectangle of spacing and spacing, many triangles, semicircle.

Adopted the heat-exchangers of the plate type of technique scheme, because no corrugated sheet, so the heat exchanger plates direct heat transfer is contactless thermal resistance.Because fluid inlet is established by bending part in the both sides of heat exchanger plates, another bending end face is a fluid issuing, so can form countercurrent flow.Because heat exchanger plates can suppress ripple in any position easily, thus can be according to fluid heat exchange needs, and full section or segmentation suppress ripple on heat exchanger plates, obtain as far as possible little fluid resistance enhanced heat exchange effect to greatest extent with this.Contactless thermal resistance, countercurrent flow, ripple have increased direct heat transfer area and disturbance enhanced heat exchange, and these can greatly improve heat exchanger effectiveness.

Because this heat-exchangers of the plate type directly forms with banded flat plate folding is stacked, two bending end face formings seal naturally and need not to seal again, and only both sides must seal combination, for example can seal with the pressing easily of side slat section bar, so make easily, sealing is also fine simultaneously.

The shape of this heat-exchangers of the plate type, size, fluid inlet and outlet orientation can both combine with building is good in addition, so make the fresh air ventilator of building application more widely will be arranged.

Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.By folding heat exchanger plates stacked shape be divided into cuboid, multilayer V-type cylinder, individual layer V-type cylinder etc., specific embodiment of every kind of correspondence.

The specific embodiment

First specific embodiment is rectangular build, referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, Fig. 5, this heat exchanger is made up of heat exchanger plates (1) and side slat (2), heat exchanger plates (1) is to become passageway (6) with wide banded flat plate folding, promptly be similar to the folded form of snakelike comb, be stacked to cuboid, the both sides of heat exchanger plates (1) lean on bending (5) to locate to be provided with fluid inlet (4) with some side slats (2) pressing sealing, the both sides of heat exchanger plates.Fluid inlet (4) can be made into the bar frame (8) of band flow deflector (9) supporting, and this frame (8) is connected as a single entity with side slat (2) and is convenient to the pressing sealing.In order not increase the fluid inlet resistance, the deckle board up and down of bar frame (8) can exceed side slat and be boss (10), the corresponding cooperation of concave station (12) of this boss (10) and adjacent side slat up and down.Fluid inlet also can be without the bar frame, and heat exchanger plates is directly bonding with adjacent side slat up and down.Fluid issuing (7) on fluid inlet (4) and the bending end face also can exchange as required.

Heat exchanger plates (1) can suppress the various ripples (3) that help augmentation of heat transfer in addition, and the side slat face (11) that is in contact with it is also for corrugated accordingly.Top and bottom position at heat exchanger plates can be mainly used in the heat exchanger on the above-mentioned fresh air ventilator as being close to paths in each passageway that folds out a big spacing with non-Heat Conduction Material in addition.

Second specific embodiment is multilayer V-type cylinder type, referring to Fig. 6, Fig. 7, Fig. 8 and Fig. 9, Figure 10, heat exchanger plates (1) is to become passageway (6) with the banded flat plate folding of stairstepping, promptly be similar to the folded form of snakelike comb, the limit, top side of heat exchanger plates (1) all is placed in the gap (15) of correspondence of side slat flat board (16), make large carrying food-basket (17) and the pressing sealing with side slat flat board (16) arch, the stacked pressing sealing of corresponding dovetail wedge shape side slat (18) is all used in the grouping of root side.Side slat flat board (16) described here is to be arranged in parallel within on the flexible flat board by many side slats (2), and the conjunction that becomes one.The adjustable triangle of passageway (6) spacing is adopted in folding bending (5).

The banded flat board of stairstepping can cut into a pair of connection along the F line and use referring to Figure 10 in addition.Each folds out the passageway of a big spacing as being close to paths each position, little V-arrangement district (19) that in addition can be in cylinder.Other structure and first specific embodiment are basic identical.

The 3rd specific embodiment is individual layer V-arrangement cylinder type, and referring to Figure 11, Figure 12, heat exchanger plates (1) is to become passageway (6) with wide banded flat plate folding, and its root side is all used corresponding wedge shape side slat (20) pressing sealing.Other structure and second specific embodiment are basic identical.

Is that example is sketched its course of work below in conjunction with accompanying drawing with first specific embodiment, referring to Fig. 1, Fig. 2 and Fig. 3, two fluids are respectively through the fluid inlet (4) of two ends both sides band flow deflectors (9) separately, enter the passageway (6) of each interval in the heat exchanger, pass through flat board, corrugated plating (3), flat board then, with as far as possible little fluid resistance, heat exchange is strengthened in the adverse current disturbance to greatest extent, discharges through bending (5) end face fluid issuing (7) separately respectively at last.
