Description

Technical Field

[0001] The utility model relates to the technical field of air-to-air coolers, and particularly relates to an inner wall cleaning structure for an air-to-air cooler. Background Art

[0002] An air-to-air cooler (also known as an air-air cooler) is a heat dissipation device that uses air as a cooling medium and realizes heat exchange through internal and external double-cycle air paths. It is mainly used in scenarios such as fully enclosed high-voltage motors and chemical equipment to solve the problem of heat discharge of high-temperature fluids or equipment inside.

[0003] The working principle of an air-to-air cooler is to use air as a cooling medium. The pipes arranged in parallel inside it are key components, and high-temperature fluids that need to be cooled flow inside these pipes. Power drives the impeller to rotate to generate eddy currents, continuously sucking in cold air. After the cold air contacts the hot pipes, heat is transferred, cooling the hot substances inside the pipes. Due to its advantages such as compact structure, small floor area, and simple operation, the air cooler is widely used in multiple industries.

[0004] The deficiencies of the above prior art solutions are as follows: When the above air-to-air cooler operates, grease substances and dust particles are likely to accumulate on the outer side of its pipes. This is mainly because the high-temperature process fluids (such as crude oil and lubricating oil) in the surrounding environment contain volatile oil and gas components. If these dirt deposits are not cleaned for a long time, they are likely to cake, seriously hindering heat transfer and thus affecting the subsequent heat transfer effect of the air cooler. At the same time, because the pipes inside the air-to-air cooler are dense, it is not convenient to clean, thereby increasing the maintenance difficulty. Content of the Utility Model

[0005] The utility model provides an inner wall cleaning structure for an air-to-air cooler, which can solve the problem that grease and particles are likely to accumulate on the surface of the pipes when the air-to-air cooler in the prior art is in use and it is not convenient to clean.

A plurality of groups of diversion pipes are arranged in parallel inside the shell. Fins for increasing the heat dissipation area and extending along the direction of the diversion pipes are arranged on the side of each group of diversion pipes. The cleaning mechanism includes a cleaning plate, and a plurality of sliding holes for slidingly matching with the corresponding diversion pipes and fins are formed on the cleaning plate. The combined longitudinal section shape of the diversion pipe and the fin is the same as the longitudinal section shape of the sliding hole. At least one fixing plate is fixedly arranged inside the shell, and the space between the two ends of the shell is evenly divided by the fixing plate. The surface of the end of the diversion pipe is smoothly arranged. The corresponding diversion pipes located inside the shell are connected end to end. Each fixing plate is arranged at the connection position of the diversion pipes. A plurality of cleaning plates are arranged and are all slidingly matched on the corresponding diversion pipes.

The middle of the support sliding rod is fixedly connected to the fixing plate. Each group of cleaning plates is slidingly matched with the support sliding rod.

[0014] Advantages of the utility model:

[0015] Before cleaning the utility model, it is necessary to spray caustic soda solution on the surface of the diversion tube and the fins first, so that the stains on the surface of the diversion tube and the fins are moistened for a period of time, which is used to reduce the cleaning difficulty and also can reduce the friction force on the surface of the diversion tube.

[0024] The following will describe in detail the specific implementation manners of the utility model, but it should be understood that the protection scope of the utility model is not limited by the specific implementation manners.

[0025] As Figures 1 to 4 shown, a cleaning structure for the inner wall of an air-to-air cooler provided by an embodiment of the present utility model includes a cleaning mechanism 4 arranged in cooperation inside the housing 1. As Figure 2 shown, a plurality of groups of diversion tubes 2 are arranged in parallel inside the housing 1, and fins for increasing the heat dissipation area are arranged on the side of each group of diversion tubes 2 along the direction of the diversion tubes 2. High-temperature air flows from one end of the diversion tubes 2 to the other end, and its temperature will be conducted to the fins. Since the fins have a large contact area, the heat dissipation area can be increased. The cleaning mechanism 4 includes a cleaning plate 402, and a plurality of groups of sliding holes 405 that are slidably matched with the corresponding diversion tubes 2 and fins are formed on the cleaning plate 402. The composite longitudinal section shape formed by the combination of the diversion tubes 2 and the fins is the same as the longitudinal section shape of the sliding holes 405. A pushing assembly 401 for driving the cleaning plate 402 to move along the surface of the diversion tubes 2 is arranged in cooperation between the inner wall of the housing 1 and the cleaning plate 402. During use, before cleaning, an alkali solution (the alkali solution is a mixed solution of sodium hydroxide, sodium bicarbonate, sodium silicate, and water) needs to be sprayed on the surfaces of the diversion tubes 2 and the fins first, so that the stains on the surfaces of the diversion tubes 2 and the fins are moistened for a period of time to reduce the cleaning difficulty and also reduce the friction on the surface of the diversion tubes 2. The pushing assembly 401 drives the cleaning plate 402 to move, so that the side wall of the sliding hole 405 can scrape off the stains on the diversion tubes 2 and the fins. In this embodiment, the pushing assembly 401 is preferably a pneumatic telescopic rod, and the influence of the high-temperature environment on the pneumatic telescopic rod is small.

[0026] Among them, at least one group of fixing plates 3 is fixedly arranged inside the housing 1. The fixing plates 3 evenly divide the space between the two ends of the housing 1. The surface of the end of the diversion tube 2 is smoothly arranged, which is convenient for the installation of the diversion tube 2 and the collection of stains. Each group of diversion tubes 2 is arranged between the housing 1 and the fixing plate 3 or between the fixing plates 3, and the ends of two adjacent groups of diversion tubes 2 in the axial direction are connected. For specific reference Figure 3 to two specific embodiments. A plurality of groups of cleaning plates 402 are arranged, and all of them are slidably matched on the corresponding diversion tubes 2. Connecting plates 403 are fixedly arranged on the sides of all the cleaning plates 402. The connecting plates 403 can play a role in transmission. When one group of cleaning plates 402 is pushed, all the cleaning plates 402 can be driven to move through the connecting plates 403, so as to realize the common cleaning of multiple sections of diversion tubes 2.

[0027] In a group of specific embodiments, as Figure 3 shown, one group of fixing plates 3 is arranged. Each group of diversion tubes 2 is fixed between the fixing plate 3 and the housing 1. Two groups of cleaning plates 402 are arranged, and the distance between the two groups of cleaning plates 402 is the same as the distance between the fixing plate 3 and the end of the housing 1.

[0028] In another group of specific embodiments, as Figure 5As shown in the figure, there are two sets of fixed plates 3. Each set of diversion pipes 2 is fixed between the fixed plate 3 and the housing 1 or between two adjacent sets of fixed plates 3. There are three cleaning plates 402, and the distance between adjacent cleaning plates 402 is the same as the distance between two adjacent sets of fixed plates 3.

[0029] The number of the fixed plates 3 and the cleaning plates 402 can be changed according to the total length of the diversion pipes 2, so as to ensure the cooling effect of the hot air. Other technical solutions that are further improved only by changing the number of the fixed plates 3 and the cleaning plates 402, such as the technical solution with three sets of fixed plates 3 and four sets of cleaning plates 402, all fall within the protection scope of this patent.

[0030] On the same side of each cleaning plate 402, a layer of silica gel layer 406 is fixedly arranged. The long-term working temperature of silica gel can reach 180°C, while the temperature range of the cooling object of the air-air cooler generally does not exceed 150°C, which can ensure that the physical properties of the silica gel layer 406 remain stable after long-term contact with the diversion pipe 2. The cleaning plate 402 is preferably made of alumina ceramic material to ensure that the cleaning plate 402 will not deform in a high-temperature environment. During cleaning, the cleaning plate 402 is used to scrape off the stains on one side of the diversion pipe 2, and the silica gel layer 406 is used to fully scrape off the alkali solution on the surface of the diversion pipe 2, so that more alkali solution can accumulate in front of the sliding hole 405 when the cleaning plate 402 moves, which can clean, moisten and reduce friction on the surface of the diversion pipe 2, and at the same time can also realize the collection of the alkali solution until all the alkali solution and stains are scraped to the smooth end of the diversion pipe 2, and finally the stains and alkali solution are cleaned by a high-pressure blower. During cleaning, the output port of the high-pressure blower is aligned with the smooth end of the diversion pipe 2 stained with alkali solution and stains, and the blowing operation is repeated to blow off the alkali solution and stain blocks from the diversion pipe 2. If necessary, a water gun can be used for auxiliary cleaning. Since the position to be cleaned is between the cleaning plate 402 and the housing 1 or between the cleaning plate 402 and the fixed plate 3, in a narrow space, the high-pressure blower and the water gun can give full play to their cleaning functions to ensure the maintenance effect of the diversion pipe 2. Finally, the inside of the housing 1 is cleaned, and after the stains in the housing 1 are rinsed off, the maintenance operation of the cooler is completed.

[0031] There are two sets of connecting plates 403, which are symmetrically and fixedly arranged on both sides of all the cleaning plates 402. There are two sets of pushing components 401. A U-shaped groove 404 is opened on the side of the connecting plate 403 far from the center of the cleaning plate 402. Each set of pushing components 401 is located inside the corresponding U-shaped groove 404. The U-shaped groove 404 structure of the connecting plate 403 has a certain stable supporting property, which can ensure the transmission effect of the cleaning plate 402 while also protecting the pushing components 401.

[0032] Such as Figure 3 Or Figure 5As shown in the figure, a support slide bar 5 is fixedly arranged inside the outer shell 1 along the extending direction of the diversion pipe 2. The middle of the support slide bar 5 is fixedly connected to the fixed plate 3, and each cleaning plate 402 is slidably matched with the support slide bar 5.

[0033] Working principle: Before cleaning, an alkali solution (the alkali solution is a mixed solution of sodium hydroxide, sodium bicarbonate, sodium silicate and water) needs to be sprayed on the surface of the diversion pipe 2 and the fins first, so that the stains on the surface of the diversion pipe 2 and the fins are moistened for a period of time to reduce the cleaning difficulty and also reduce the friction on the surface of the diversion pipe 2. Start the pushing component 401 to push a group of cleaning plates 402 to move, and drive all the cleaning plates 402 to move through the connecting plate 403, so as to realize the common cleaning of multiple sections of the diversion pipe 2, so that the side wall of the sliding hole 405 can scrape off the stains on the diversion pipe 2 and the fins until all the alkali solution and stains are scraped to the smooth end of the diversion pipe 2. Finally, the stains and the alkali solution are cleaned by a high-pressure blower to realize the rapid cleaning of the diversion pipe 2 and the fins.

[0034] During cleaning, the cleaning plate 402 is used to scrape off the stains on one side of the diversion pipe 2, and the silica gel layer 406 is used to fully scrape off the alkali solution on the surface of the diversion pipe 2, so that more alkali solution can be gathered in front of the sliding hole 405 when the cleaning plate 402 moves, which can play the roles of cleaning, moistening and reducing friction on the surface of the diversion pipe 2, and at the same time, the collection of the alkali solution can be realized to reduce the subsequent drying difficulty.

[0035] The above discloses only several specific embodiments of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
