Current widely used double pipe heat exchanger, tubular heat exchanger, plate type heat exchanger etc. can only realize the synchronous heat exchange between two media, along with the development of science and technology and the needs of real technique, the application of three mediums composite heat-exchanger more and more receives attention, medium all needs to be heated by a kind of medium of steam, or is cooled etc. by a kind of medium of cooling water.The such as application of various pairs of material heaters (heat pump such as air-ground energy, air-solar energy) and two material cooling device (automobile radiator systems).
At present, the heat exchanger of cross-current configuration is less, and three medium heat exchanging devices now known are only limitted to board-like, shell-bushing type and fin-bushing type etc.
Chinese patent " CN101762192A " discloses a kind of brazing plate type heat exchanger, it is made up of the first plate group be set up in parallel and the second plate group heat exchange core body, first medium ostium and tap hole on the bottom heat exchange tube sheet of the first plate group, and the second adjacent plate group end heat exchanger plates on second medium ostium and tap hole be set to blind hole, and add rigid gasket at two board blind hole gap locations the second medium flow channel of the first medium flow channel of the first plate group and the second plate group is isolated, achieve a kind of medium simultaneously with two media heat exchange or two media simultaneously respectively with another kind of media for heat exchange.This contrive equipment is simple, but device bearing pressure is little, conducts heat uneven.
For valve jacket tubular type and fin double pipe heat exchanger, annular space between inner sleeve and the inwall of outer tube forms a medium channel, the tube chamber of inner sleeve forms another medium channel, and the inwall of housing and the outer wall of outer tube form the 3rd medium channel.But in this structural tube, medium and the outer medium heat of sleeve pipe exchange insufficient, and heat distribution is uneven, causes heat exchange efficiency low, and heat exchanger takes up an area space greatly, and the metal wastage of unit heat transfer area is large.Therefore it is little to be generally applicable to flow, the occasion that required heat transfer area is less.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides that a kind of structure is simple, heat exchange is even, heat exchange efficiency is high, bearing capacity is large, easy-to-dismount novel fin-tube type three medium heat exchanging device of good airproof performance, device.
Its technical scheme is: comprise upper cover plate, lower cover, front package strip, rear package strip, honeycomb type fin, mozzle, the intermediate package honeycomb type fin of upper cover plate, lower cover, front package strip and rear package strip, upper cover plate has first medium entrance, lower cover has first medium outlet, the upper end of front package strip and the lower end of rear package strip have second medium entrance and second medium outlet, the top and bottom of left and right package strip have the 3rd medium inlet and the 3rd media outlet
Mozzle is installed vertically on the side of honeycomb type fin, and mozzle divides first medium conduit and two groups, second medium conduit, walks different medium respectively, and the first medium is flowed down along first medium conduit by the import of upper cover plate, is exported flow out by the first medium of lower cover;
The second medium enters opening's edge second medium conduit by second medium and flows down, and the second medium outlet along rear strip of paper used for sealing is flowed out, thus realizes the noiseless flowing of two media;
The third medium can by left package strip the 3rd medium inlet flow into, flow in honeycomb type fin, after from right package strip the 3rd media outlet flow out;
After honeycomb type fin and mozzle pass to medium respectively, in honeycomb type fin, medium is conducted heat by the tube wall of mozzle and first medium and second medium, achieves the composite heat-exchange between three media.
The position that the position that above-mentioned first medium conduit is installed is installed higher than second medium conduit.
Above-mentioned honeycomb type fin comprises pressure strip, honeycomb type fin and mozzle under pressure strip on core body, core body, and described honeycomb type fin and mozzle to be fixed under pressure strip on core body, core body between pressure strip.
The beneficial effects of the utility model are: first medium and second medium carry out flowing heat transfer by independent conduit and the 3rd medium separately through honeycomb type fin structure, increase the pressure scope of application of heat exchange structure, compared with double pipe heat exchanger, bearing pressure increases, can realize a kind of medium simultaneously with two media heat exchange or two media simultaneously respectively with another kind of media for heat exchange, honeycomb type fin makes heat exchange more even, abundant, increases heat transfer efficiency.
