Description
Technical field
The present invention relates to a kind of spiral heat exchangers, more particularly, to a kind of spiral heat exchanger of center augmentation of heat transfer.
Background technology
Existing spiral heat exchanger as shown in Figure 1, due to making apparatus and spiral heat exchanger this body structure
On limitation, by the size of spiral-plate heat exchanger, center circle diameter is differed from 200mm to 500mm.In this way, working as material
After entering heat exchanger center circle (two semicircular cylinders for being equivalent to certain radius and height), material can be gathered slowly, flowing speed
Degree greatly reduces.As a result, the material after entering center semicircle, is only and inner ring heat exchanger plates (spiral heat exchanger plates
The innermost circle of piece) and the material of center heat exchanger plates contact portion can carry out heat exchange.But the stream of the material due to this part
Dynamic speed is very low, so its film coefficient of heat transfer very little, thus the efficiency of its heat exchange is very low.It is such the result is that center heat exchanger plates with
And inner ring heat exchanger plates, the heat exchanger plates of this part cannot effectively play the effect of heat exchange, reduce the effective heat exchange area of heat exchanger
(and the professional standard of existing spiral-plate heat exchanger and spiral-plate heat exchanger is in the calculation all using the area of this part as spiral shell
The effective heat exchange area of spiral plate exchanger).When such result is likely to cause actual motion, spiral-plate heat exchanger cannot meet
Technological requirement.

In the second spiral flow channel of second medium, the end and side of first spiral flow channel and the second spiral flow channel are only
Vertical sealing, and first medium import, first medium outlet, second medium import and second medium outlet, two kinds of Jie are opened up respectively
It is mutual indepedent when matter flows into and out in heat exchanger, it exchanges heat in respective spiral flow channel, the first spiral heat exchange
It is respectively equipped with and its interior space shape one between plate and the innermost circle plate and center heat exchanger plates of the second spiral heat exchange plate
The guide shell of cause, the guide shell are the tubular construction of side openings formula, and a side of open side is connect with center heat exchanger plates,
And the barrel other positions and center heat exchanger plates of the guide shell, the first spiral heat exchange plate and the second spiral heat exchange plate it is equal between
It every being respectively formed center heat exchanger channels, and is connected to respectively with the first spiral flow channel and the second spiral flow channel so that center
Heat exchanger plates and the innermost circle plate of the first spiral heat exchange plate and the second spiral heat exchange plate play the role of effective heat exchange.
Further, the first medium import is opened in the guide shell that the first spiral flow channel innermost circle communicates therewith
Lower end, the first medium outlet are opened in the outmost turns side of the first spiral flow channel；The second medium import opens up
In the outmost turns side of the second spiral flow channel, the second medium exports the innermost circle for being opened in the second spiral flow channel and its
The upper end of the guide shell of connection.First medium is flowed and is discharged toward outer ring from the inner ring of overall heat exchange device, and second medium is from whole
The outer ring of body heat exchanger is flowed and is discharged to inner ring, and two media comes into full contact with and exchanges heat.
First medium enters the central space of the guide shell of its place runner from first medium import, then with certain flow rate
Be introduced into and channel be formed by by center heat exchanger plates and guide shell, pass through innermost circle plate by the first spiral heat exchange plate with
The channel that guide shell is formed finally enters the first spiral flow channel；Second medium enters the from side second medium entrance
Two spiral flow channels, the innermost circle plate of the guide shell and the second spiral heat exchange plate of runner where keeping certain flow rate to be introduced into it
Piece is formed by channel, pass through by the guide shell and center plate package at channel, finally flow into inside guide shell, by the
Second medium outlet outflow, during this, center heat exchanger plates and the first spiral heat exchange plate and the second spiral heat exchange plate it is most interior
The fluid of girth sheets piece both sides keeps certain flow velocity, can reach the state of turbulent flow, also substantially increase spiral-plate heat exchanger
Heat transfer efficiency, achieve the purpose that augmentation of heat transfer.
Further, the first medium outlet and second medium entrance are respectively equipped with the first liquid collecting bobbin carriage and the second collection
Liquid pipe case.First medium import and first medium outlet are located on respective guide shell, which can replace collector tube
Case and the first and second liquid collecting bobbin carriage play the role of buffering in medium inlet and outlet jointly.
Further, the barrel of the guide shell is arranged one or more bracing ring, the bracing ring outer ring and center
Heat exchanger plates and the first spiral heat exchange plate or the second spiral heat exchange plate are fixed, and the antifatigue energy of conveyor screw entirety is improved
Power.
Advantageous effect：Compared with prior art, advantages of the present invention is：First, guide shell is added at the center of heat exchanger,
Enable center heat exchanger plates and the medium of the innermost circle plate both sides of spiral heat exchanger plates to reach required flow velocity, increases simultaneously
Its contact area to exchange heat achievees the effect that augmentation of heat transfer；Secondly, it is logical to bear two with bracing ring as one jointly for guide shell
The pressure of medium in road, thus its bear the ability of external pressure and be improved, increase its whole anti-fatigue ability, extend and change
The service life of hot device.
