Abstract

The utility model relates to a plate-type heat exchanger whose end face is shaped and sealed, which comprises a heat exchanging plate and a side slat, the heat exchanging plate is superposed by a belted flat plate which is folded to be a clipping channel, the bending end face is naturally to be shaped and sealed, only both sides of the heat exchanging plate is compressed and sealed by the side slat, both sides which are adjacent to the bending portion are provided with liquid inlets, and the heat exchanging plate can be compressed to be flow marks according to needs. The heat exchanger which adopts the technique, since has adverse current, none contact thermal resistance and increased direct heat exchanging face, which is disturbed to be reinforced to exchange heat, thereby heat exchanging efficiency is higher and liquid resistance is small. Since only two lateral faces are sealed, and the plate-type heat exchanger can adopt section bars that flow deflector concave-convex stage and the side slat are integrated, therefore, the sealing is more reliable, and manufacturing is simpler.

Description

End face forming sealed heat-exchangers of the plate type

One, technical field

The utility model relates to a kind of heat-exchangers of the plate type.

Two, 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.

Three, summary of the invention

It is higher that the purpose of this utility model provides a kind of heat exchanger effectiveness, and better tightness is made easier heat-exchangers of the plate type simultaneously.

For achieving the above object, technical solution adopted in the utility model 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 ripple 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, the end face of another bending 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.
