Description

Technical Field

[0001] This patent relates to the field of heat exchange equipment, and in particular to a heat exchanger inlet air pre-cooling wet film that also serves as a water blocking and guiding device. Background Technology

[0002] In the field of heat exchange equipment, heat exchangers are crucial devices that transfer heat from one medium to another to meet various process requirements. In the field of refrigeration systems, heat exchangers are an indispensable component, achieving cooling by exchanging heat with the refrigerant. In the field of wet film cooling technology, wet film is a highly efficient evaporative cooling technology that absorbs heat from the air through the evaporation of the wet film, thereby achieving a cooling effect.

[0003] In existing technologies, the heat exchanger's heat exchange capacity can be improved by adding a wet film to the outer surface of the heat exchanger. This method can effectively improve the heat exchanger's heat exchange capacity, thereby increasing the efficiency of the refrigeration system. However, it is usually impossible to avoid water droplets from the wet film entering the unit, causing corrosion and seriously affecting the unit's lifespan. Utility Model Content

[0004] In view of this, this application provides an air inlet pre-cooling wet film, comprising: a wet film, which is a rectangular plate structure and is placed vertically; a water collection tray disposed below the wet film; a spray diversion chamber disposed above the wet film, wherein a diverter is disposed in the spray diversion chamber; a water-blocking and guiding assembly, which is sheet-shaped and whose front side covers the back side of the wet film; a fixing plate assembly, which consists of two symmetrical sheet metal parts disposed on the water collection tray and respectively covering the two end faces of the wet film, wherein the fixing plate assembly is used to fix the wet film and the water-blocking and guiding assembly; and a top cover sealing plate disposed on the upper end face of the spray diversion chamber, thereby cooperating with the fixing plate assembly to make the air inlet pre-cooling wet film a whole structure.

[0005] By adopting the above-mentioned specific structure, a water-blocking and flow-guiding component is set behind the wet film, which can prevent excess moisture on the wet film from being carried into the heat exchanger by the airflow, thereby protecting the sheet metal parts in the unit from rusting, increasing the service life and safety of the unit.

[0006] As one possible implementation, the water-blocking and guiding assembly includes multiple guide vanes, each guide vane being elongated and distributed parallel to the water-blocking and guiding assembly. Each guide vane has a recess, with a first extension extending from the recess in a direction perpendicular to the front of the fixing plate assembly, and a second extension extending from the recess in a direction perpendicular to the back of the fixing plate assembly. Multiple first water-blocking strips extend obliquely downward from the lower end of the recess, and second water-blocking strips extend from the second extension in the opposite direction to the extension direction of the first water-blocking strips. A limiting portion is provided at the top of the water-blocking and guiding assembly, and the cross-sectional length of the limiting portion is not less than the cross-sectional length of the guide vane.

[0007] Using the above possible implementation methods, the recesses, first extensions, second extensions, first water-blocking strips, and second water-blocking strips in multiple guide vanes form a reverse scale turbulence structure. This structure is similar to the arrangement of reverse scales in fish. When large water particles enter with the airflow, they will change their flow direction under the action of this special structure and be collected in the recesses.

[0008] As one possible implementation, the water-blocking and guiding assembly is provided with guide grooves on both sides, and a guide sponge is provided in the guide groove, with the guide sponge in contact with the multiple guide blades.

[0009] Using the above-mentioned possible implementation method, the water collected in the recess flows into the guide channel, and then smoothly flows into the water collection tray along the guide sponge.

[0010] As one possible implementation, a diversion sponge is disposed between the spray diversion chamber and the wet film, and the spray diversion chamber presses the diversion sponge tightly above the wet film.

[0011] Using the above-mentioned possible implementation methods, the water sprayed from the distributor first enters the distribution sponge before entering the wet film. The distribution sponge can form a uniform distribution surface, which can refine the particle size of the incoming wet film.

[0012] As one possible implementation, one end of the diverter is fixed to the spray diverting chamber, and the other end of the diverter is connected to an external water source. The diverter is provided with multiple spray holes, through which the diverter can effectively spray water onto the diverting sponge.

[0013] As one possible implementation, the fixing plate assembly is provided with a first sliding groove that cooperates with the wet film. The first sliding groove is used to limit the wet film, and a plurality of clamping brackets are provided in the first sliding groove for clamping the wet film.

[0014] As one possible implementation, the fixed plate assembly is provided with a second sliding groove that cooperates with the water-blocking and guiding assembly, the second sliding groove being used to limit the water-blocking and guiding assembly.

[0015] As one possible implementation, the water collection tray is provided with multiple support members, which elevate the wet membrane to prevent the wet membrane from directly contacting the water accumulated in the water collection tray.

[0016] As one possible implementation, the side or bottom end face of the water collection tray is provided with a drain hole or drain pipe for draining the water accumulated in the water collection tray.

[0017] As one possible implementation, the wet membrane is integrally molded from organic or inorganic polymer materials; the diversion sponge and the drainage sponge are made of polyester polyol and polyisocyanate materials. Attached Figure Description

Detailed Implementation

[0031] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0032] This application provides an inlet pre-cooling wet film that prevents moisture on the wet film from entering the unit, thus preventing corrosion and rust, and impacting the unit's lifespan and safety. Figure 1 As shown, it is specifically composed of a wet film 100, a water collection tray 300, a spray diversion chamber 500, a water blocking and guiding assembly 200, a fixed plate assembly 400, and a top cover sealing plate 800.

[0033] Among them, such as Figure 1 , 10 As shown, the wet membrane 100 has a rectangular plate-like structure and is placed vertically. The wet membrane 100 has a porous structure that can store water.

[0034] In this embodiment, the wet membrane 100 is integrally molded from organic or inorganic polymer materials. Specifically, the wet membrane 100 uses plant fiber or glass fiber as the substrate, is generated through resin processing, and possesses both corrosion resistance and flame retardancy, as well as high water absorption capacity. Furthermore, in other embodiments, other types of wet membranes can be selected according to requirements.

[0035] In this embodiment, the wet film 100 has a thickness of 50 mm, a width of 320 mm, and a height of 310 mm. Alternatively, in other embodiments, wet films 100 of other sizes can be selected according to actual needs.

[0036] Among them, such as Figure 1 , 11 As shown, the water collection tray 300 is positioned below the wet membrane 100 to support the wet membrane 100 and collect excess water from it. The water collection tray 300 contains multiple support members 310 that elevate the wet membrane 100, preventing it from directly contacting the water accumulated in the tray. The water collection tray 300 is constructed from fully welded sheet metal parts and undergoes a smoothing process.

[0037] In this embodiment, as Figure 1 , 11 As shown, a drain hole 320 is provided on the side end face of the water collection tray 300 for draining accumulated water from the water collection tray 300. The drain hole 320 cooperates with a drain pipe to drain the accumulated water, and the outer diameter of the drain pipe is 10 mm. In other embodiments, the drain hole 320 may be located on the bottom end face of the water collection tray 300.

The spray distribution chamber 500 is composed of sheet metal parts fully welded together and has undergone a smoothing process.

[0041] In this embodiment, as Figure 1 As shown, a distributor 600 is provided in the spray distribution chamber 500. One end of the distributor 600 is fixed on the spray distribution chamber 500, and the other end of the distributor 600 is connected to an external water source. The distributor 600 is provided with multiple spray holes. Through the multiple spray holes, the distributor 600 can effectively and evenly spray water onto the wet film 100.

[0042] In this embodiment, the spray distribution chamber 500 is made of stainless steel with a plate thickness of 0.8-1.5 mm, and is formed using a full welding process. Its dimensions are 338 mm in length, 92 mm in width, and 19 mm in height. In other embodiments, spray distribution chambers 500 of other sizes can be selected according to actual needs.

[0043] In this embodiment, the diverter 600 uses a DN10 (nominal diameter 10 mm) PPR (Polypropylene Random Copolymer) water pipe. Alternatively, in other embodiments, copper or stainless steel pipes may also be used.

[0044] In this embodiment, the nozzle diameter on the distributor 600 is 1-3 mm, and the spacing between the nozzles is 10 mm. Both ends of the distributor 600 are fixed to the inner surface of the spray distribution chamber 500 by clamps. Alternatively, in other embodiments, distributors 600 of other sizes can be selected according to actual needs.

[0045] Among them, such as Figure 1 As shown, a diversion sponge 700 is disposed between the spray diversion chamber 500 and the wet film 100, and the spray diversion chamber 500 presses the diversion sponge 700 tightly against the upper end of the wet film 100. The water sprayed from the diverter 600 enters the diversion sponge 700 before entering the wet film 100. The diversion sponge 700 can form a uniform diversion surface, which plays a role in refining the particle size of the incoming flow to the wet film 100.

[0046] In this embodiment, the diversion sponge 700 has a length of 320 mm, a width of 50 mm, and a height of 20 mm. Alternatively, in other embodiments, other sizes of diversion sponge 700 can be selected according to actual needs.

Multiple first water-blocking strips 234 extend obliquely downwards from the lower end of the recess 231, and second water-blocking strips 235 extend from the second extension 233 in the opposite direction to the extension of the first water-blocking strips 234. The recess 231, the first extension 232, and the second extension 233 in the multiple guide vanes 230, together with the first water-blocking strips 234 and the second water-blocking strips 235, form a reverse-scale turbulence structure. This structure is similar to the arrangement of reverse scales on a fish. When large water particles enter the guide vane 230 with the airflow, their flow direction changes under the action of this special structure, and they are collected in the recess 231.

[0049] In this embodiment, as Figure 9 As shown, the first extension 232 and the second extension 233 are inclined and stepped, and have the function of guiding and blocking flow.

The limiting part 220 is used to protect the guide vane 230 from above, preventing the guide vane 230 from interfering with other devices when the water-blocking and guiding assembly 200 is removed from above the air inlet pre-cooling wet film embodiment of this application, which would cause damage to the guide vane 230 and reduce the water-blocking effect.

[0052] In this embodiment, the water-blocking and guiding component 200 is made of stainless steel with a plate thickness of 0.8-1.5 mm. The water-blocking and guiding component 200 is formed using a welding process. Its dimensions are 320 mm in length, 33 mm in thickness, and 330 mm in height.

The first slide groove 410 has a width of 51 mm, and the second slide groove 420 has a width of 16 mm. In other embodiments, fixing plate assemblies 400 of other sizes can be selected according to actual needs.

[0056] Among them, such as Figure 1 As shown, the top cover sealing plate 800 is disposed on the upper end surface of the spray diversion cavity 500, thereby cooperating with the fixed plate assembly 400 to make the air inlet pre-cooling wet film embodiment involved in this application a whole structure.

[0057] In this embodiment, the top cover sealing plate 800 is made of stainless steel with a thickness of 0.8-1.5 mm, and is formed by sheet metal machining. Its dimensions are 338 mm in length and 92 mm in width, and it is fixedly sealed to the spray distribution chamber 500 using fasteners. Alternatively, in other embodiments, other sizes of the top cover sealing plate 800 can be selected according to actual needs.
