The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.
The present invention is directed to the deficiency that prior art exists, a kind of novel plate type heat exchanger with pulsating heat pipes is provided.Before and after heat exchanger fin 1 substrate, on two sides, be all milled with the groove 7 of snakelike heat pipe shape, use front shroud 12 and back shroud 13 to cover welding simultaneously, above-mentioned cover plate 12,13 (as Fig. 5) forms with groove 7 heat exchanger fin 1 that is similar to the heat exchange of pulsating heat pipe principle; Groove 7 at above-mentioned heat exchanger fin is laid some rectangular opening-substrate through-hole 8 around, and the part of not laying substrate through-hole 8 is equivalent to heat exchanger fin 10, can effectively solve the difficult problem that pulsating heat pipe heat exchanger is difficult for installing additional fin like this; Utilize the staggered enclosure interior that is plugged in of a plurality of heat exchanger fins, not only increased the operation contact area of heat exchanger inner fluid, and combined the advantage of heat exchange of heat pipe, plate type heat exchanger and fin, heat exchange efficiency is high, heat exchange amount is large, heat exchanger fin is easy to dismounting, and operation is not subject to the impact of gravitational field.
Concrete: heat exchanger is mainly by having certain thickness, based on pulsating heat pipe principle, prepare heat exchanger fin 1, dividing plate 2 (as shown in Figure 1, the cold and hot medium of this heat exchanger is separated by dividing plate 2, the import and export that heat exchanger rear and front end is medium), sealing ring and heat exchanger shell 3 form.
Heat exchanger fin 1: the groove 7 that is all milled with snakelike heat pipe shape on the two sides of heat exchanger fin substrate, and the orthographic projection of the groove in either side substrate plane 7 overlaps completely with the orthographic projection of substrate plane upper groove 7 at opposite side, make substrate and front and rear cover plate 12, 13 form the heat pipe passage based on pulsating heat pipe principle jointly, groove circumferentially-periodic is all established some rectangular through-hole 8, and heat exchanger fin substrate and dividing plate 2 contact portions are entity 9 (not having through hole), and with the front and rear cover plate 12 being laid with substrate identical rectangular hole, 13 take the welding manner formula heat exchanger fin (as Fig. 7) that is combined as a whole.
Preferably, the heat exchanger fin 1 in the present invention has two kinds of versions, and the position of the groove that difference is heat exchanger fin substrate on two kinds of heat exchanger fins rectangular opening is around different, and the rectangular opening installation position of two kinds of heat exchanger fins just in time staggers up and down; When assembling, two kinds of heat exchanger fin space assemblings, need alternately to insert in heat exchanger shell as shown in Figure 1, make the duct of the MEDIA FLOW warp certain angle that all staggers up and down, behind the duct of the heat exchanger fin by a kind of structure, directly touch another kind of structure heat exchanger fin, increased the mobile pulsation situation of medium, increase heat exchange area and time of contact, increase heat exchange area, improved heat exchange efficiency, as shown in Figure 4.
Shown in Fig. 3, be heat exchanger fin substrate structure figure, heat exchanger fin substrate shown in this example is that thickness is the copper coin of 9mm, the groove 7 that the degree of depth is 3mm heat pipe shape is opened respectively in both sides, the surrounding of heat pipe shape leaves the welding semifinished product of 1mm width, heat exchanger fin other parts except semifinished product and groove 7 are drilled with some rectangular opening-substrate through-hole 8 as shown in Figure 4, as the runner of medium.In the middle of heat exchanger fin substrate with dividing plate 2 fit the position that contacts be entity 9 as shown in Figure 4, do not hole, by sealing ring, sealed, the sealing ring draw-in groove 11 that there is the rubber seal of carrying dividing plate 2 inside as shown in Figure 6, completely cuts off the mixing of cold and hot medium so completely.The upper end sealing of outer cover of heat exchanger adopts same procedure.The entity part of not beating rectangular opening on heat exchanger fin has played the fin effect of installing additional.
In sum, by being combined to form pulsating heat pipe heat exchanger fin 1 with front and rear cover plate, being made of one formula pulsating heat pipe heat exchanger fin, on heat exchanger fin, perforation is as medium runner, be equivalent to install additional fin left and right, under the phase-change heat transfer of Forced Convection Heat Transfer and pulsating heat pipe and the augmentation of heat transfer acting in conjunction of TRANSFER BY PULSATING FLOW, the heat exchange efficiency that effectively improves this heat exchanger forms new and effective plate type heat exchanger with pulsating heat pipes.
Heat exchanger shell 3: as shown in Figure 2, heat exchanger shell 3 is integrated with dividing plate 2, and the upper end of housing 3 arranges upper cover plate 4, and one end of this upper cover plate 4 is fixing in hinged way, the other end can freely be opened, and heat exchanger is changed heat exchanger fin 1 by freely opening of upper cover plate 4.
Heat exchanger shell 3 upper ends with on dividing plate 2, be provided with heat exchanger fin slot 5 through holes identical with heat exchanger fin size, facilitate the replacing that pulls and pushes of heat exchanger fin, dividing plate 2 and heat exchanger fin 1 contact portion and heat exchanger upper end and heat exchanger fin contact portion are opened multiple-sealed draw-in groove 11 at its edge correspondence position respectively, to take up sealing ring; Lower bottom part at housing is milled with for carrying the right-alternative groove 6 in a left side of heat exchanger fin, and adjacent notches 6 needs offset certain distance, as shown in Figure 2.
Together with the multiple tracks rubber seal (as shown in Figure 6) of this heat exchanger dividing plate 2 and housing 3 upper ends is embedded in housing when arranging simultaneously, while inserting heat exchanger fin, can fit tightly with heat exchanger fin, cold fluid and hot fluid can alternately enter heat transfer space successively like this, avoids it to mix, and reaches the object of heat exchange.
The working media of described pulsating heat pipe is any one or more combination in distilled water, methyl alcohol, absolute ethyl alcohol, acetone, freon, nano-fluid, and the heat exchanger fin of extracting heat exchanger out fills working media, adopts scolding tin sealing after filling.Because this heat exchanger heat exchanger fin can be extracted out, be convenient to the replacing to working media, to reach the different coefficients of heat transfer that require.
Described heat exchanger shell 3 is made by stainless steel, and heat exchanger outside is surrounded by one deck heat-insulating shield, by polystyrene extruded plastic formula warming plate, is made, and described heat exchanger fin 1 and dividing plate 2 are made by copper coin, and described sealing ring adopts rubber seal.In view of dividing plate 2 and outer cover of heat exchanger 3 upper ends are all provided with the heat exchanger fin slot 5 of heat exchanger fin shape, so need strict sealing, sealing employing rubber seal, rubber seal can be born higher temperature, and not yielding, good sealing effect, guarantees the isolation completely of cold and hot medium.
During the work of this heat exchanger, in heat exchanger, the fluid at cold and hot interval carries out efficient heat exchange under the phase-change heat transfer of Forced Convection Heat Transfer, pulsating heat pipe and the acting in conjunction of enhanced fin heat transfer.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
