Detailed implementation manners

[0021] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the detailed implementation manners and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention.

[0023] The following describes an efficient and energy-saving air-cooled air-conditioning heat exchanger provided by some embodiments of the present invention with reference to the accompanying drawings. Embodiment 1:

[0024] Combined with Figures 1-12 As shown, an efficient and energy-saving air-cooled air-conditioning heat exchanger provided by the present invention includes an exchanger mechanism 100, a mesh surface cleaning mechanism 200 disposed on the exchanger mechanism 100, four sets of net releasing mechanisms 300 symmetrically distributed on the exchanger mechanism 100, four sets of net receiving mechanisms 400 symmetrically distributed on the exchanger mechanism 100, and four air duct filters 500 disposed in the four sets of net releasing mechanisms 300 and the four sets of net receiving mechanisms 400. The exchanger mechanism 100 is used for heat exchange treatment of internal and external circulating air. The mesh surface cleaning mechanism 200 is used for cleaning the dirt and small flying insects on the four air duct filters 500. The four sets of net releasing mechanisms 300 are used for orderly winding the worn parts of the four air duct filters 500. The four sets of net receiving mechanisms 400 are used to cooperate with the four sets of net releasing mechanisms 300 to effectively replace the worn mesh surface.

[0025] The exchanger mechanism 100 includes a box net 130, four outer guard plates 140, and four inner guard plates 150. A slideway is provided between adjacent outer guard plates 140 and inner guard plates 150. Two top plates 110 disposed at the top and bottom of the box net 130, and four sets of wing plates 120; Among them, four rectangular guide net grooves 160 are provided between the four wing plates 120 and one of the top plates 110, and the guide net grooves 160 are used to provide limit guidance for the mesh surface of the air duct filter 500; Rectangular key positions are provided at the corners of the top plate 110 and the ends of the wing plates 120; The four air duct filters 500 are disposed outside the four end faces of the box net 130 to block large particulate impurities and small flying insects in the internal and external circulating air; The mesh surface cleaning mechanism 200 includes a shock net scraping member 290 movably installed in the four outer guard plates 140 and the four inner guard plates 150, and the shock net scraping member 290 is composed of four blades and four L-shaped sliders; The net releasing mechanism 300 includes a first winding roller 340 and two grinding wheels 350 installed on the two end heads of the first winding roller 340, and the first winding roller 340 is used to provide a carrier for co-winding the worn air duct filter 500; The net receiving mechanism 400 includes a second winding roller 460 and two deflection gears 470 installed on the two end heads of the second winding roller 460, and the second winding roller 460 is used to provide a carrier for winding the new part of the air duct filter 500.

[0026] At present, there are certain defects when the exchanger used in the air conditioner exchanges heat through the internal and external air circulation. The internal and external circulating air will carry dust and small flying insects, and the mesh holes of the exchanger are relatively large. The carried dust and small flying insects will adhere to the radiator fins or the heat exchanger core under the influence of moisture. As the exchanger operates for a long time, the radiator fins or the heat exchanger core will be corroded. In severe cases, the efficiency of the exchanger for air circulation treatment will be reduced, thereby increasing energy consumption.

[0027] Through the innovation of the air conditioner exchanger, four evenly distributed air duct filters 500 are arranged on the outside of the four-way box net 130. When the exposed parts of the four air duct filters 500 are pressed and tightened, a certain gap can be maintained between the tightened parts of the air duct filters 500 and the box net 130. With the circulation and exchange of the internal and external air, the dust and small flying insects carried in the air will be captured by the air duct filters 500 first; At the same time, with the start of the micro-motor 220, its internal transmission shaft will drive the winding roller 230 to rotate regularly, and the cord 240 wound by the winding roller 230 will drive the slider 280 and the vibrating net scraping part 290 to descend. At this time, the four cutting edges of the vibrating net scraping part 290 can reciprocally scrape the tightened parts of the four air duct filters 500, and with the reset thrust applied by the reset spring 270 to the slider 280, ultimately the unobstructed transmission of the four air duct filters 500 for air circulation can be achieved; Meanwhile, the actively captured dust and small flying insects will not cause blockage to the radiator fins or the heat exchanger core. Embodiment 2:

[0028] Combined with Figures 1-8 As shown, on the basis of Embodiment 1, the mesh surface cleaning mechanism 200 further includes a machine base 210 arranged on another top plate 110. A micro-motor 220 is arranged inside the machine base 210, a winding roller 230 is arranged on the internal transmission shaft of the micro-motor 220, two cushion plates 250 arranged on the machine base 210, and a housing 260 installed on the two cushion plates 250.

[0029] Preferably, the two cushion plates 250 serve as the bearing platform for the housing 260. When the housing 260 bears the pressure of the lifting rod movement of the slider 280, the two cushion plates 250 fixed by two bolts can ensure that the housing 260 will not shake due to pressure, thereby effectively ensuring the constancy of the lifting speed of the vibrating net scraping part 290 and the balance of the pressure on the four air duct filters 500.

[0030] The winding roller 230 is integrally in an I-shaped structure, and a cord 240 is wound on the winding roller 230. The top end of the cord 240 is installed with a slider 280; A slideway is opened inside the housing 260, and a reset spring 270 is arranged in the slideway; The top end of the reset spring 270 bears on the slider 280, and the bottom end of the reset spring 270 bears on the inner wall of the slideway; The slider 280 is composed of a rectangular cushion block and a cylindrical guide rod, and the other end of the cylindrical guide rod is welded to one blade of the vibrating screen scraper 290.

[0031] Preferably, according to the structure of the vibrating screen scraper 290, the number of sliders 280 can be set to two, and the micro motor 220 is set as a double-shaft motor. At the same time, the number of the winding rollers 230, the cord 240, the housing 260 and the reset spring 270 all need to be set to two. By symmetrically installing the two sliders 280 on the two blades of the vibrating screen scraper 290, with the operation of the double-shaft motor, the lifting of the two cords 240 driving the two sliders 280 will be more stable. Embodiment 3:

[0032] Combined with Figure 1 and Figure 12 As shown, on the basis of Embodiment 1, the net releasing mechanism 300 further includes a bin 310 arranged on two adjacent key positions, two assembly grooves 320 arranged on the bin 310, and the two assembly grooves 320 are located on the outer walls of the two rectangular columns of the bin 310; A cylindrical cavity is formed in the inner cavity of the bin 310, and a discharge slot 330 is formed in the protruding plate surface of the bin 310; Holes adapted to clamp the two end shafts of the first winding roller 340 are formed in the concave holes at both ends of the bin 310, and sealing washers are arranged in the holes.

[0033] Preferably, an antioxidant can be injected into the cylindrical cavity inside the bin 310 to provide protection for the newly stored air duct filter screen 500. Among them, the bin 310 is made of stainless steel material, and a protective paint layer is coated on the bin 310; When the antioxidant is injected into the bin 310, a rubber pad needs to be arranged on the inner side of the discharge slot 330 to prevent the overflow of the antioxidant.

[0034] Two screw sleeves 360 are arranged on the bin 310, a pressurizing screw rod 370 is movably installed in the screw sleeve 360, and a plug pad 380 is clamped on the head at the bottom of the pressurizing screw rod 370; The plug pad 380 is attached to the end face of the grinding wheel 350 and is provided with a corrugated slot.

[0035] During use, it is necessary to use a wrench to adjust the two pressurizing screw rods 370. When the two pressurizing screw rods 370 are loosened, the grinding wheel 350 and the first winding roller 340 will be loosened. Then, by applying a pulling force to the other end of the air duct filter screen 500, the new mesh surface wound on the first winding roller 340 can be pulled outwards, and finally it will replace the worn part of the air duct filter screen 500. Embodiment 4:

[0036] Combined Figure 11 and Figure 12 As shown, in the above embodiment, the net receiving mechanism 400 further includes a cushion 410 disposed in the assembly groove 320, two pin posts 420 fixedly mounted on the outer wall of the cushion 410, and a sub-spring 430 disposed on the pin posts 420; One end of the sub-spring 430 bears on the head of the pin post 420, and the other end of the sub-spring 430 bears on the limit clamping plate 440.

[0037] Preferably, the cushion 410 is fixedly mounted on the silo 310 by bolts, and the protrusion inside the cushion 410 penetrates into the assembly groove 320. The deflection gear 470 is located in the inner cavity of the assembly groove 320. When the cushion 410 seals the assembly groove 320, the protrusion inside the cushion 410 will limit the outer wall of the deflection gear 470 to prevent the deflection gear 470 from shaking during rotation.

[0038] Two adjacent cushions 410 are used to provide calibration protection for both ends of the second winding roller 460; A jack is provided in the middle of the cushion 410, and an adjusting end 450 is disposed in the jack; The adjusting end 450 is composed of a shaft rod, a hexagonal end and a gear, and the tooth openings of the gears are adapted to mesh with the tooth openings of the deflection gear 470; Both the first winding roller 340 and the second winding roller 460 are composed of a rubber sleeve roller and a stainless steel core rod.

[0039] Preferably, one end of the gear inside the adjusting end 450 fits on the stainless steel core rod inside the second winding roller 460. As the adjusting end 450 is adjusted, the gear will assist in rotating the deflection gear 470. At this time, the deflection gear 470 will drive the second winding roller 460 to rotate stably as a whole, so as to orderly wind the worn part of the air duct filter screen 500 to avoid the problem of rebound during the winding of the air duct filter screen 500. When the adjustment is completed, the limit clamping plate 440 can be released until the limit clamping plate 440 fixes the adjusting end 450.

[0040] The working principle and usage process of the present invention: The air-conditioning air-cooled and heated heat exchanger is mainly based on air flow and heat transfer. Using a fan or natural wind, air is made to pass through the radiator fins or the heat exchanger core. When the air passes through the radiator fins or the heat exchanger core containing heat, the air can absorb heat and then become hot air. The hot air will then be driven to the outside of the system, and the heat will be dissipated into the environment through natural convection or forced convection of the same specification. At the same time, the cold air outside the system is inhaled, cooled by the heat exchanger, and then circulated back into the system; However, this circulation of external air will bring certain defects to the air-cooled heat exchange. Since the internal and external airflows circulate, dust and small flying insects in the environment will inevitably be carried into the radiator fins or the heat exchanger core of the exchanger. Moreover, the volume of small flying insects is relatively large. Once they remain in the radiator fins or the heat exchanger core, the heat exchange efficiency of the radiator or the heat exchanger core for air will decrease. In severe cases, problems such as mold will appear inside the radiator fins or the heat exchanger core. Especially after the central air conditioner is arranged in the duct and operates for a long time, the air output from the radiator fins or the heat exchanger core will have problems such as peculiar smell; This device innovates the traditional air-cooled heat exchanger. When the exchanger mechanism 100 is installed inside the central air conditioner as shown in the following attachment Figure 1 in this way, the four box-shaped meshes 130 will be located in the ventilation apertures inside the air conditioner, and the four evenly distributed air duct filters 500 will be located outside the four box-shaped meshes 130. At this time, a certain gap will be maintained between the partially tightened air duct filter 500 and the box-shaped mesh 130; When the central air conditioner operates for a long time, the air in the internal and external circulation will be initially filtered by the air duct filter 500, and the filtered air will enter the box-shaped mesh 130 and finally reach the radiator fins or the heat exchanger core inside the box-shaped mesh 130. At this time, sundries such as dust or small flying insects carried in the air can be screened by the air duct filter 500; As the dust or small flying insects accumulate, after the micro motor 220 operates, it will drive the winding roller 230 to rotate, and the winding roller 230 will wind up the tie rope 240. At the same time, the top of the tie rope 240 will pull the slider 280 and the shock mesh scraping part 290 to descend along the four air duct filters 500 as a whole. At this time, the four cutting edges inside the shock mesh scraping part 290 can apply an inward squeezing force to the exposed part of the air duct filter 500. Under the reset thrust of the return spring 270, the regularly moving winding roller 230 can prompt the shock mesh scraping part 290 to scrape along the four exposed parts of the four air duct filters 500 in sequence. By deforming the exposed part of the air duct filter 500 under pressure, dust and small flying insects and other sundries can be made to fall towards the bottom of the device; When the central air conditioner has been used for a certain period of time and needs to be overhauled, use a wrench to adjust the hexagonal ends at the tops of multiple pressure-boosting screws 370, causing the pressure-boosting screws 370 to rotate counterclockwise. At this time, the gasket 380 will be in an initial relaxed state. Then, stretch the adjacent two limit clamping plates 440 outwards and use a screwdriver to adjust one of the adjusting ends 450. At this time, the gear at the inner end of the adjusting end 450 can drive the deflecting gear 470 to rotate. The loose grinding wheel 350 and the first winding roller 340 will continuously release the air duct filter screen 500, and the used part of the air duct filter screen 500 will be wound onto the second winding roller 460 until the new part of the air duct filter screen 500 moves and replaces the old part. Finally, tighten the light pressure-boosting screw 370 clockwise and adjust the adjusting end 450 to continue rotating until the new part of the air duct filter screen 500 is tightened; Finally, clean the entire device according to the cleaning requirements.

[0041] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
