The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Fig. 1 and Fig. 2 show structural representation of the present utility model, and as seen from Figure 1, the heat exchange section of jurisdiction comprises coil pipe 1 and filler 2.Coil pipe 1 has adopted serpentine coil.
About connected mode, can be by welding, engaging mode or connector, above-mentioned filler 2 is fixed in and the heat exchanger tube of coil pipe 1 between.Such as, connector is tied rope F, beats one or more fixing holes at the edge of filler 2, passes fixing hole with a tied rope, and it is bundled on the corresponding heat exchanger tube 11 securely.If the heat exchanger tube of coil pipe is round tube or oval pipe, can also select to adopt the engaging mode, U-shaped groove is arranged at the edge that is about to filler, is placed in wherein steadily with the heat exchanger tube with coil pipe.The filler that is arranged between the adjacent heat exchange tubes can be a slice, also can be multi-disc.
The heat exchanger tube spacing is from being positioned at the upper strata of accepting first spraying cooling water to the rear lower floor that accepts spraying cooling water and diminishing gradually or becoming large, to prolong the heat-exchange time of cooling water in the filler, reduce the temperature difference of lower floor's heat exchanger tube and cooling water, thereby improve the heat transfer effect of heat exchanger tube and cooling water.
The straight length of heat exchanger tube have along the liquid in pipe flow direction to or sloped of upstroke, and the straight length gradient is big or small identical or different, when being during to descending slope, can reduce the Pressure Drop of liquid in pipe from import to outlet.
The length of the straight length of heat exchanger tube increases gradually or reduces from being positioned at upper strata to the rear lower floor that accepts spraying cooling water that accepts first cool water shower.Such mode can increase the larger blower fan of size that air inlet is installed in the constant situation of condenser appearance and size, can add Wind Volume like this, thereby improve heat transfer effect.
Fig. 3 shows another preferred heat exchange section of jurisdiction of the present utility model, comprises coil pipe 1 and filler 2.Be with above-described embodiment one difference, in the heat exchange section of jurisdiction, the straight length of the heat exchanger tube 11 of coil pipe 1 is parallel to each other, past lower floor dwindles or increases its tube pitch gradually from the upper strata, correspondingly, the radius of curvature of the bending section of heat exchanger tube 11 is also dwindled gradually, the use of filler 2 and with the connected mode of coil pipe 1, can be with reference to above-described embodiment.When tube pitch from the upper strata toward lower floor when dwindling gradually, the heat exchanger tube 11 on upper strata is accepted first spray cold water, then from upper extremely to downstream to the heat exchanger tube 11 that is positioned at lower floor; When high temperature refrigerant enters then from exporting 4 when flowing out from import 3, because the tube refrigerant temperature of last layer is higher than the temperature of lower one deck, so every water temperature rise ratio through last layer heat exchanger tube 11 is higher through the water temperature liter of lower one deck heat exchanger tube 11, so the filler 2 of last layer is lengthened, is used for prolonging the heat-exchange time of filler 2 cooling waters.With respect to above-described embodiment one, present embodiment is in the temperature difference that reduces lower floor's heat exchanger tube and cooling water, thereby the heat transfer effect aspect of raising heat exchanger tube and cooling water is even better.
Fig. 4 shows another preferred heat exchange section of jurisdiction of the present utility model, comprises coil pipe 1 and filler 2.Be with above-described embodiment one difference, the straight length of described heat exchanger tube 11 have along the liquid in pipe flow direction to descending slope, this liquid in pipe is high temperature refrigerant.When being during to descending slope, after high temperature refrigerant entered from import 3, the mobile of this cold-producing medium was along the direction to descending slope, flowed out until export 4.Because it is certain for descending slope that heat exchanger tube 11 has along the direction that flows, with respect to embodiment one, present embodiment has reduced the Pressure Drop of cold-producing medium from import to outlet more highlightedly.
Heat exchanger fin in above-described embodiment is applied to the coil pipe evaporating heat exchanger.Be such as but not limited to, as shown in Figure 5, this condenser comprises coil heat exchanger 5, blower fan 6, water pump 7, water-locator 8, collecting-tank 9 and framework 10; Wherein heat exchanger is one group, described coil heat exchanger 5 is comprised of many heat exchange sections of jurisdiction in above-described embodiment, these many heat exchange sections of jurisdiction connect to form by inlet header and outlet header, wherein serpentine coil 1 vertically arranges, and namely the length direction of the straight length of the heat exchanger tube of this serpentine coil is consistent with the cooling air direction.
Another preferred heat exchange section of jurisdiction of the present utility model has been shown among Fig. 6, has comprised coil pipe 1 and filler 2.Be with above-described embodiment one difference, in the heat exchange section of jurisdiction, the flow development length of heat exchanger tube 11 increases to lower one deck gradually from last layer, when increasing gradually, the heat exchanger tube 11 on upper strata is accepted first spray cold water, then from upper to downstream to the heat exchanger tube 11 that is positioned at lower floor.The heat exchange section of jurisdiction that present embodiment provides is more suitable for adopting the evaporative condenser of two groups of heat exchangers.With respect to embodiment one, present embodiment can be in the constant situation of condenser appearance and size, and the length of the straight length by changing heat exchanger tube 11 is installed the more blower fan of large scale and horsepower.Consult again Fig. 6, the heat exchange section of jurisdiction that the blower fan of solid line part provides for having adopted present embodiment, the blower fan of dotted portion is the heat exchanger fin of the heat exchanger tube with isometric straight length shown in the embodiment one.Comparatively speaking, the former employed blower fan (solid line) is larger than the size of the employed blower fan of the latter (dotted line), can add Wind Volume like this, thereby improves heat transfer effect.
Operation principle of the present utility model: high temperature fluid enters serpentine coil 1 through inlet header, this moment, water pump was transported to the water at low temperature in the collecting-tank water-locator 8 at serpentine coil top, and spray is to the very thin moisture film of outer surface formation of serpentine coil, in conjunction with Packed vertical serpentine coil, make cooling water flow dirty in lower floor heat exchanger tube surface in the guiding of filler 2 behind heat exchanger tube surface, upper strata, realize guiding and broadcast water.Meanwhile, blower fan 6 is introduced space, evaporative condenser place with temperature and the lower wind of relative humidity, make itself and heat exchanger and the cooling water of flow through heat exchanger and filler carries out sufficient heat exchange, evaporation after the heat absorption of part water in the moisture film, all the other fall into collecting-tank 9, supply-water pump circulation usefulness flows out from outlet header after the fluid of high temperature is cooled into cryogen simultaneously.
It should be noted that the above only for preferred embodiment of the present utility model, be not so limit scope of patent protection of the present utility model that the utility model can also carry out the improvement of material and structure by parts, or employing technical equivalents thing is replaced.So the equivalent structure that all utilizations specification of the present utility model and diagramatic content are done changes, or directly or indirectly apply to other correlative technology fields and all in like manner all be contained in the scope that the utility model contains.
