End plate 30.During work, high-temperature gas enters housing 10 inner chamber from the air inlet 11 of housing 10, and
On heat exchange fin 20, heat exchange is carried out with the cryogen in heat exchanger tube 40.The present invention can be further
Preferably countercurrent heat exchange method, the relatively low tube fluid of temperature enters from the one end away from air inlet 11 and changes
Inside hot device, i.e. the one end being positioned at housing 10 basal surface position in Fig. 1 enters heat exchanger tube 40 inside, stream
It is positioned at the one end on housing 10 end face to heat exchanger tube 40, carries out heat exchange so that water flow temperature raises,
Current after final heating are discharged from housing 10 end face.Current after heating can be used for factory other
Technique produces and Plant personnel shower needs.
Unilateral relatively refer to that multiple heat exchange fin 20 is sequentially arranged, between adjacent two heat exchange fins 20
Arrange face to face.
Deflection plate 50 is also included in housing 10.Two deflection plates 50, two bafflings it are additionally provided with in housing 10
Plate 50 is divided into three heat exchange area by internal for housing 10, is respectively defined as first area 501, second
Region 502 and the 3rd region 503.Sequentially connect above-mentioned multiple additionally, also have multiple air channel 60
Heat exchange area.Specifically, the air channel 60 of the present embodiment includes the 601, second air channel, the first air channel
602.First area 501 keeps connecting by the first air channel 601 with the same side of second area 502.
The homonymy of the side and the 3rd region 503 that are not provided with the first air channel 601 on second area 502 passes through
Second air channel 602 keeps connection.The present invention is by being divided into inside housing 10 at multiple deflection plates 50
Multiple heat exchange area, extend heat exchange journey long, beneficially the miniaturization of device and high efficient heat exchanging.
Air inlet 11 is opened in first area 501 and is not provided with the side in the first air channel 601, air outlet
13 are opened in the 3rd region 503 is not provided with the side in the first air channel 601.Gas is from air inlet 11
After entering housing 10 inner chamber, it is introduced into first area 501, then flow to the first wind from first area 501
Road 601, changes path through the first air channel 601 and flow to second area 502, through second area 502
Rear arrival the second air channel 602, arrives the 3rd region 503 after the second air channel 602 changes path,
Finally housing 10 inner chamber is flowed out from air outlet 13 behind the 3rd region 503.
It is noted that in this embodiment of the present invention, the first air channel 601 and the second air channel
Track in 602 is linear.Air channel 60 can be to be made by perforate on deflection plate 50, this
Kind design, manufacture more convenient, need not specially die sinking, be greatly saved manufacturing cost.
Additionally, air inlet 11 connects what housing 10 inner chamber was demarcated by deflection plate 50 with air outlet 13
Multiple regions, air inlet 11 and air outlet 13 are tubaeform,
Embodiment two
The air compressor waste heat recovery that Fig. 2 show schematically show according to embodiments of the present invention in two is changed
Hot device.In this embodiment of the present invention, as in figure 2 it is shown, the first air channel 601 and the second air channel
The inwall of 602 is smooth surface transition, and the design in preferred arc surfaced air channel 60, and it has excellent
Drainage effect, it is possible to the resistance of balance heat exchanger tube 40 outer high temperature heat exchanging fluid flowing, and balance everywhere
Air pressure, prevents the appearance at dead angle, it is ensured that air compressor conforms at the pressure reduction through heat exchanger
Ask.
In the scheme of air channel 60 smooth surface transition, it not be used in perforate on deflection plate 50, typically pass through
The housing 10 of rolling definite shape is formed.It is evenly arranged heat exchanger tube 40 outer fluid, improves further and change
Thermal effect.
Other technologies scheme is identical with embodiment one, and the present embodiment is not repeating.
Embodiment three
As it is shown on figure 3, on the basis of the arc surfaced air channel 60 of above-described embodiment 2, the wind of the present invention
Arc drainage plate 70 can be further provided with in road 60.Arc drainage plate 70 is welded on deflection plate 50
At the end in arc surfaced air channel 60, and it is equipped with arc surfaced air channel 60 inwall, preferably arc
The curvature of drainage plate 70 is more than the curvature of arc surfaced air channel 60 inwall, and both cambered surfaces are the most curved
Song, can form smooth flow of gas passage, can drain further, balance air pressure everywhere.Specifically,
The arc drainage plate 70 increased in arc surfaced air channel 60, on the flow direction of heat exchanger tube 40 outer fluid,
Arc drainage plate 70 coordinates with housing 10 inwall of smooth surface transition, defines and first uniformly attenuates,
The flow section of uniformly overstriking again, in further defining air channel, wind speed first raises the flowing spy reduced afterwards
Property, beneficially being sufficiently mixed and the reequilibrate of temperature of fluid in air channel, is conducive to improving next and changes
Heat transfer effect everywhere in thermal region.In the conception of the present invention, arc drainage plate 70 can also be with
Deflection plate 50 is wholely set.
Embodiment four
Fig. 4 show schematically show a kind of deformation of above-described embodiment three.Between multiple heat exchange fins 20 admittedly
Surely being provided with four pieces of deflection plates 50, housing 10 inner chamber is divided into five heat transfer zone by four pieces of deflection plates 50
Territory, 4 air channels 60 are sequentially connected with above-mentioned heat exchange area.Concrete, five heat exchange area define respectively
It is district of district of district of district 701, two 702, three 703, four 704 and five districts 705.One side, district 701
Arranging air inlet 11, a district 701 is not provided with the side of air inlet 11 and is connected by the 3rd air channel 603
Same lateral position in two districts 702.Two districts 702 are not provided with the side in the 3rd air channel 603 by the 4th
Air channel 604 is communicated in the same lateral position in three districts 703.Three districts 703 are not provided with the 4th air channel 604
Side is communicated in the same lateral position in four districts 704 by five-duct 605.It is not provided with in four districts 704
The side of five-duct 605 is communicated in five districts 705 by the 6th air channel 606.
Heat exchange fin 20 in housing 10 inner chamber has been divided into more multi-region by above-mentioned multiple deflection plate 50
Territory, substantially increases heat exchange journey long.High-temperature gas is after entering in housing 10, through multiple heat exchange
The heat exchange in region, it is ensured that the heat of high-temperature gas can sufficiently and heat exchange fin 20 completes heat
Exchange, improves heat recovery rate further.
Compared to prior art, the Advantageous Effects of the present invention is, high-temperature gas and low temperature current
Forming adverse current, i.e. low temperature flow direction is that last heat exchange area sensing first is changed from heat exchanger
After thermal region, high-temperature gas and heat exchange fin generation heat exchange, the heat exchange fin after heating is again by heat
Passing to low temperature current in heat exchanger tube 40, the heat making air compressor discharge in the course of the work obtains
To fully reclaiming, and the temperature regulating water at low temperature stream entrance heat exchanger just can control compressed-air actuated sky
The outlet temperature of gas, the heat that low temperature current absorb when flowing to first heat exchange interval is constantly incremented by,
Air compressor can be solved because of energy recovery not exclusively, thus it is properly functioning to affect air compressor,
Or use cooler to cause polluting environment, the problem of thermal waste, it is also possible to improve air compressor
The waste heat recovery rate of compressed gas and energy utilization rate.
