Description

Technical Field

[0001] This invention relates to the field of evaporative cooling device technology, specifically to a dedicated motor assembly for evaporative coolers and its usage method. Background Technology

[0002] An evaporative cooler can be viewed as a combined heat exchanger of a cooler and a cooling tower, using water as the cooling medium. Typically, in industry, to save water in water-cooled coolers, water is cooled in a cooling tower and recycled. An evaporative cooler, however, combines the cooler and cooling tower into one unit. The process fluid to be cooled flows inside the tubes, while water and air simultaneously flow outside. The heat of the fluid inside the tubes is transferred to the air through the water outside, achieving the cooling purpose. Air is drawn in from the lower perimeter of the evaporative cooler, passing through the gaps in the horizontally arranged heat transfer tube bundle. Cooling water is drawn in from a reservoir by a circulating water pump and sprayed onto the heat transfer tubes. Some of the water evaporates, and the remaining water collects in the reservoir, where it is recycled along with the makeup water. The process fluid enters the tube bundle from the upper header and flows out from the lower header.

[0003] The existing dedicated motor assembly for evaporative coolers has the following problems: 1. The existing equipment only cools the introduced air and then blows the cooled air into the motor assembly to achieve cooling, but it cannot exchange heat with the hot air from the outside; 2. When the equipment operates in a dusty environment, a large amount of impurities and dust will enter the equipment, causing damage or affecting the internal structure of the equipment. Summary of the Invention

[0008] Preferably, a central vertical plate is fixedly connected to the end of the stepped cover away from the protective shell, and interpenetrating blocking plates are symmetrically arranged on both sides of the central vertical plate. The interpenetrating blocking plates are inserted through the outside of the stepped cover and extend into the inside. Reset springs are fixedly connected to both the upper and lower ends of the interpenetrating blocking plates, and a straight plate is fixedly connected to the end of the reset spring away from the interpenetrating blocking plate. The straight plates are symmetrically connected to the top and bottom of the stepped cover.

[0009] Preferably, the outer side of the protective cover is provided with a transverse groove, a spring is fixedly connected to the inner side of the transverse groove, a sliding rod is fixedly connected to the end of the spring away from the transverse groove, the sliding rod is slidably adapted to the inside of the transverse groove, a bent rod is fixedly connected to the outer end of the sliding rod, a sleeve is fixedly connected to the end of the bent rod away from the sliding rod, and the sleeve is fixedly connected to the outer side of the inserting blocking plate.

[0010] Preferably, a second pull rope is fixedly connected to the side of the slide rod near the stepped cover, and a first pull rope is fixedly connected to the end of the second pull rope away from the slide rod. A fulcrum plate is slidably adapted to the outer side of the first pull rope, and the fulcrum plate is fixedly connected to the bottom of the stepped cover. The end of the first pull rope away from the second pull rope passes through the surface of the protective cover and is fixedly connected to the filter screen.

[0011] Preferably, a first magnet is fixedly connected to the end of the slide bar away from the bending rod, and an embedded rod is symmetrically connected to both sides of the servo motor housing. A second magnet is fixedly connected to the end of the embedded rod away from the servo motor, wherein the first magnet and the second magnet maintain a repulsive relationship.

[0012] Preferably, the cooling mechanism includes a first processing frame and a second processing frame. A first exhaust plate is fixedly connected inside the first processing frame, and a second return pipe is fixedly connected to the top of the first processing frame. A second exhaust plate is fixedly connected inside the second processing frame, and a first return pipe is fixedly connected to the top of the second processing frame. A water tank is fixedly connected to the bottom of both the first and second return pipes, and the water tank is fixedly connected to the bottom of the protective cover.

[0013] Preferably, a transition plate is fixedly connected to the bottom of both the first and second processing frames. The transition plate has holes on its surface and is fixedly connected to the bottom of the water tank. A distribution pipe is provided above both the first and second processing frames. A return pipe is fixedly connected to the outside of the distribution pipe, and the bottom end of the return pipe is fixedly connected to the top of the water tank. A spray head is fixedly connected to the bottom of the distribution pipe. There are several spray heads, which are fixedly connected to the top of the first and second processing frames respectively. An arc-shaped cover is fixedly connected to the outside of the spray head, and a snap-fit ​​plate is fixedly connected to the inner end of the arc-shaped cover. The snap-fit ​​plate is fixedly connected to the inside of the first and second processing frames respectively, and a wet curtain is fixedly connected to the bottom of the snap-fit ​​plate.

[0014] The method for using a dedicated motor assembly for an evaporative cooler includes the following steps: Step 1: Unsealing process. Move the inserting blocking plate along the inner wall of the stepped cover to both sides and stretch the reset spring strip. The reset spring strip is elastic and it resets the inserting blocking plate. At this time, the opening on the stepped cover that was originally blocked by the inserting blocking plate will open. Step 2: Filtration. Using the fulcrum plate as the compression point, the No. 1 pull rope applies a force to the left to the filter screen fixed to its other end. However, the top of the filter screen is rotatably connected to the ring support through the adapter ring. Therefore, the filter screen will deflect clockwise around the ring support to filter impurities in the hot air. Step 3: Cooling. The hot air passing through the No. 1 and No. 2 processing frames will impact the wet curtain. When the hot air passes through the wet curtain, the water on the surface of the wet curtain evaporates and absorbs heat, and the air temperature drops. At this time, the hot air will be transformed into cold air and discharged from the tail end of the No. 2 processing frame, and re-enter the left chamber of the protective cover to cool down the motor assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The opening on the stepped cover that was originally blocked by the inserting plate will open, thus preparing for the subsequent entry of hot air. At the same time, the sealing of the stepped cover by the inserting plate prevents external hot air from affecting the motor components when the servo motor is not turned on.

[0016] 2. The stepped cover is stepped, with the inner diameter being the smallest at the end closest to the protective shell and the largest at the end furthest from the protective shell. This effectively collects the large, dispersed flow of hot air rising from the heat source surface, preventing the hot air from spreading and stagnating around the heat source. At the same time, the hot air entering from the large opening is gradually gathered and compressed as it flows towards the small opening, creating a negative pressure (pull) throughout the pipe. This guides the hot air entering from all directions towards the central axis.

[0017] 3. The top of the filter screen is rotatably connected to the ring support via an adapter ring. Therefore, the filter screen will deflect clockwise around the ring support, which will reduce the inner diameter of the filter holes on the surface of the filter screen and increase the filtration effect.

[0018] 4. When hot air passes through the wet curtain, the water on the surface of the wet curtain evaporates and absorbs heat, causing the air temperature to drop. At this time, the hot air will be converted into cold air and discharged from the tail end of the second processing frame, and re-enter the left chamber of the protective cover to cool down the motor assembly. The entire cooling mechanism not only cools down the outside environment, but also cools down the motor assembly. Attached Figure Description

[0034] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 14The present invention provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a flow guiding mechanism 2, which is used to introduce the hot air from the molding process into the interior of the device; Cooling mechanism 3 is used to cool the motor. A protective cover 1 is fixedly installed on the inner side of the cooling mechanism 3, and a diversion mechanism 2 is fixedly installed on the outer side of the protective cover 1. An opening plate 4 is fixedly installed at the end of the protective cover 1 away from the diversion mechanism 2. A motor assembly 5 is fixedly installed inside the protective cover 1. A baffle plate 7 is symmetrically connected to both ends of the motor assembly 5. A traction plate 6 is fixedly connected to the bottom of the inner cavity of the protective cover 1.

[0036] The diversion mechanism 2 includes a double-headed rod 21, which is fixedly connected to the inner side of the protective cover 1. A patch 22 is fixedly connected to the end of the double-headed rod 21 away from the protective cover 1. A servo motor 23 is fixedly connected to the end of the patch 22 away from the double-headed rod 21. A fan blade 24 is connected to the output end of the servo motor 23 through a coupling. A ring rail 25 is fixedly connected to the outer side of the housing of the servo motor 23. A slider 26 is slidably adapted inside the ring rail 25. A bearing 27 is pressed onto the end of the slider 26 away from the ring rail 25. An external threaded plate 28 is pressed onto the side of the bearing 27 away from the slider 26. An internal threaded plate 29 is threadedly connected to the outer side of the external threaded plate 28. The end of the internal threaded plate 29 away from the external threaded plate 28 is fixedly connected to the outer side of the output end of the servo motor 23.

[0037] like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, a filter assembly 20 is fixedly installed on the outer side of the protective housing 1. The filter assembly 20 includes a stepped cover 201, wherein the stepped cover 201 is stepped, and the inner diameter of the end near the protective housing 1 is the smallest, while the inner diameter of the end away from the protective housing 1 is the largest. This allows for more effective collection of large-area, dispersed hot airflow rising from the surface of the heat source, preventing hot air from spreading and lingering around the heat source.For heat sources with a large heating area and uneven heat distribution, this design is much more efficient than a small intake. The airflow is accelerated within the stepped casing 201, meaning the cross-section decreases, and the flow velocity theoretically increases due to the continuity equation and Bernoulli's equation. Simultaneously, the fan blades 24 actively draw in air, all for the purpose of convergence. After convergence, when it enters the cooling equipment through the small opening, it forms a concentrated and compact hot airflow core, facilitating efficient processing by subsequent cooling mechanisms. The tapered pipe shape guides the airflow direction and convergence more smoothly than a suddenly contracting pipe, reducing pressure loss caused by airflow separation and vortices, thus allowing the fan blades 24 to operate with less power. This allows for the extraction of more hot air; simultaneously, the shape of the flared opening guides the hot air entering from all directions toward the central axis. The stepped cover 201 is fixedly connected to the outside of the protective shell 1. A ring support 202 is fixedly connected to the top of the inner side of the stepped cover 201. A transition ring 203 is rotatably connected inside the ring support 202. A filter screen 204 is fixedly connected to the bottom end of the transition ring 203. A central vertical plate 205 is fixedly connected to the end of the stepped cover 201 away from the protective shell 1. Symmetrical through-plates 206 are arranged on both sides of the central vertical plate 205, penetrating the outer side of the stepped cover 201 and extending into the interior. Both the upper and lower ends of the intersecting blocking plate 206 are fixedly connected to reset spring strips 207. A straight plate 208 is fixedly connected to the end of the reset spring strip 207 away from the intersecting blocking plate 206. The straight plate 208 is symmetrically connected to the top and bottom of the stepped cover 201. With the exposure of the second magnet 2006, it will repel the first magnet 2004. The other end of the first magnet 2004 is connected to the slide rod 2003. Therefore, the slide rod 2003 will compress the spring 2002 and move outward along the transverse groove 2001. The spring 2002 acts as a reset mechanism for the slide rod 2003. Then, a straight plate 208 is fixedly connected to the other end of the slide rod 2003. The bending rod 200 will move the sleeve 209 outward, where the sleeve 209 is connected to the through-blocking plate 206. Therefore, the through-blocking plate 206 will move to both sides along the inner wall of the stepped cover 201 and stretch the reset spring 207. The reset spring 207 is elastic and plays a role in resetting the through-blocking plate 206. At this time, the opening on the stepped cover 201 that was originally blocked by the through-blocking plate 206 will open, thus preparing for the subsequent entry of hot air. At the same time, the through-blocking plate 206 blocks the stepped cover 201 to prevent external hot air from affecting the motor assembly 5 when the servo motor 23 is not turned on.

[0038] A transverse groove 2001 is provided on the outer side of the protective cover 1. A spring 2002 is fixedly connected to the inner side of the transverse groove 2001. A sliding rod 2003 is fixedly connected to the end of the spring 2002 away from the transverse groove 2001. The sliding rod 2003 slides and adapts to the inside of the transverse groove 2001. A bent rod 200 is fixedly connected to the outer end of the sliding rod 2003. A sleeve 209 is fixedly connected to the end of the bent rod 200 away from the sliding rod 2003. The sleeve 209 is fixedly connected to the outer side of the through-hole plate 206. A second pull rope 2009 is fixedly connected to the side of the sliding rod 2003 near the stepped cover 201. A first pull rope 2007 is fixedly connected to the end of the second pull rope 2009 away from the sliding rod 2003. The outer side of the first pull rope 2007 slides and adapts to the outside of the first pull rope 2007. A fulcrum plate 2008 is fixedly connected to the bottom of the stepped cover 201. One end of the first pull rope 2007, away from the second pull rope 2009, passes through the surface of the protective cover 1 and is fixedly connected to the filter screen 204. Furthermore, as the slide rod 2003 moves outward, the second pull rope 2009, fixedly connected to its outer side, moves outward. The other end of the second pull rope 2009 is connected to the first pull rope 2007. Therefore, the first pull rope 2007 uses the fulcrum plate 2008 as a pressing point and applies a force to the left to the filter screen 204, fixedly connected to its other end. However, the top of the filter screen 204 is rotatably connected to the ring support 202 via the adapter ring 203. Therefore, the filter screen 204... 4 will deflect clockwise around the ring support 202, thereby reducing the inner diameter of the filter holes on the surface of the filter screen 204 and increasing the filtration effect. The end of the slide rod 2003 away from the bending rod 200 is fixedly connected to a first magnet 2004. Both sides of the servo motor 23 housing are symmetrically connected to embedded rods 2005. The end of the embedded rod 2005 away from the servo motor 23 is fixedly connected to a second magnet 2006. The first magnet 2004 and the second magnet 2006 maintain a repulsive relationship. By starting the servo motor 23, the fan blade 24 connected to its output end through the coupling will rotate in the forward direction. At this time, the hot air from the outside will be introduced into the interior of the protective cover 1, and at the same time, the servo motor 2... The internally threaded plate 29 connected to the outer side of the output end will rotate in the forward direction. The inner side of the internally threaded plate 29 is threadedly connected to the externally threaded disk 28. There is only one threaded plate 29, which is fixedly installed on the top of the servo motor 23 housing. The length of the threaded part of the threaded plate 29 is longer than the length of the threaded part of the externally threaded disk 28. Therefore, the externally threaded disk 28 driven by the threads will rotate inward with the bearing 27 that is pressed and adapted to its inner wall. The inner side of the bearing 27 is pressed and adapted to the slider 26, so the slider 26 will move inward along the annular rail 25. Then, the embedded rod 2005 fixedly connected to both sides of the servo motor 23 housing will be exposed from the inner side of the externally threaded disk 28.Simultaneously, the second magnet 2006, fixedly connected to the other end of the embedded rod 2005, will be exposed, thus providing initial support for the operation of the subsequent filter assembly 20.

[0039] With the help of the threaded drive between the external threaded disc 28 and the threaded plate 29, the external threaded disc 28 can slide outward along the preset groove on the top of the servo motor 23; even if the external threaded disc 28 slides to the end of the groove, the threaded connection between the two will not be released. Furthermore, as the external threaded disc 28 slides outward, the second magnet 2006, which was originally covered by it, will gradually be exposed.

[0040] like Figure 12 , Figure 13 and Figure 14As shown, the cooling mechanism 3 includes a first processing frame 31 and a second processing frame 32. A first exhaust plate 33 is fixedly connected inside the first processing frame 31, and a second return pipe 304 is fixedly connected to the top of the first processing frame 31. A second exhaust plate 34 is fixedly connected inside the second processing frame 32, and a first return pipe 303 is fixedly connected to the top of the second processing frame 32. Water tanks 36 are fixedly connected to the bottom ends of both the first and second return pipes 303 and 304. The water tanks 36 are fixedly connected to the bottom of the protective cover 1. The bottoms of both the first and second processing frames 31 are fixed... A transition plate 35 is connected, with holes on its surface. The bottom of the transition plate 35 is fixedly connected to the water tank 36. A distribution pipe 37 is installed above both the first treatment frame 31 and the second treatment frame 32. A return pipe 38 is fixedly connected to the outside of the distribution pipe 37, and the bottom end of the return pipe 38 is fixedly connected to the top of the water tank 36. A spray head 39 is fixedly connected to the bottom of the distribution pipe 37. Several spray heads 39 are fixedly connected to the top of the first treatment frame 31 and the second treatment frame 32, respectively. A resistor is symmetrically connected to both ends of the motor assembly 5. The partition 7 causes the motor assembly 5 and the partition 7 to divide the protective cover 1 into two chambers. Therefore, the hot air introduced by the fan blade 24 enters the right chamber of the protective cover 1. The right chamber of the protective cover 1 is connected to the first processing frame 31, so the hot air is blown into the first processing frame 31. At this time, the water pump inside the water tank 36 is activated, causing the water in the water tank 36 to be drawn into the two return pipes 38. The two return pipes 38 then introduce the water into the distribution pipe 37, and subsequently, the water in the distribution pipe 37 flows into the spray head 39. There are several water spray heads 39, which are fixedly installed on the top of the first processing frame 31 and the second processing frame 32 respectively. Then, the water spray heads 39 will spray water onto the wet curtain 302. Subsequently, the hot air passing through the first processing frame 31 and the second processing frame 32 will hit the wet curtain 302. When the hot air passes through the wet curtain 302, the water on the surface of the wet curtain 302 evaporates and absorbs heat, and the air temperature drops. Then the hot air will be converted into cold air and discharged from the tail end of the second processing frame 32, and re-enter the left cavity of the protective cover 1 to cool down the motor assembly 5. An arc-shaped cover 30 is fixedly connected to the outside of the spray head 39. A snap-fit ​​plate 301 is fixedly connected to the inner end of the arc-shaped cover 30. The snap-fit ​​plate 301 is fixedly connected to the inside of the first processing frame 31 and the second processing frame 32 respectively. A wet curtain 302 is fixedly connected to the bottom of the snap-fit ​​plate 301. The water evaporated from the surface of the wet curtain 302 will float upward to the top of the inner cavity of the first processing frame 31 and the second processing frame 32 respectively. Then it will move towards both ends along the first exhaust plate 33 and the second exhaust plate 34 respectively. Finally, it will enter the second return air pipe 304 and the first return air pipe 303 respectively, and finally return to the water tank 36, thus playing the role of water vapor return treatment.

[0041] In addition, the entire cooling mechanism 3 not only cools the outside environment, but also cools the motor assembly 5.

[0042] When using this invention: First, the servo motor 23 is started, causing the fan blade 24, which is connected to its output end via a coupling, to rotate in the forward direction. At the same time, the internal thread plate 29, which is connected to the outer side of the output end of the servo motor 23, will rotate in the forward direction. The inner thread of the internal thread plate 29 is threadedly connected to the external thread disk 28. Therefore, the external thread disk 28, driven by the thread, will move inward along the bearing 27 that is pressed and adapted to its inner wall. The inner side of the bearing 27 is pressed and adapted to the slider 26. Therefore, the slider 26 will move inward along the annular track 25. Then, the embedded rod 2005, which is fixedly connected to both sides of the housing of the servo motor 23, will be exposed from the inner side of the external thread disk 28. At the same time, the second magnet 2006, which is fixedly connected to the other end of the embedded rod 2005, will be exposed. Subsequently, magnet 2006 will repel magnet 2004. The other end of magnet 2004 is connected to slide bar 2003. Therefore, slide bar 2003 will compress spring 2002 and move outward along transverse groove 2001. Then, bent rod 200 fixedly connected to the other end of slide bar 2003 will move sleeve 209 outward. Sleeve 209 is connected to insert blocking plate 206. Therefore, insert blocking plate 206 will move to both sides along the inner wall of stepped cover 201 and stretch reset spring bar 207. At this time, the opening on stepped cover 201 that was originally blocked by insert blocking plate 206 will open. Additionally, as the slide bar 2003 moves outward, the second pull rope 2009, which is fixedly connected to its outer side, will also move outward. The other end of the second pull rope 2009 is connected to the first pull rope 2007. Therefore, the first pull rope 2007 will use the fulcrum plate 2008 as the pressing point and apply a force to the left to the filter screen 204, which is fixedly connected to its other end. However, the top of the filter screen 204 is rotatably connected to the ring support 202 through the adapter ring 203. Therefore, the filter screen 204 will deflect clockwise with the ring support 202 as the fulcrum.

[0043] The motor assembly 5 is symmetrically connected to two baffle plates 7 at both ends, which divides the protective cover 1 into two chambers. Therefore, the hot air introduced by the fan blades 24 enters the right chamber of the protective cover 1. Since the right chamber of the protective cover 1 is connected to the first processing frame 31, the hot air is blown into the first processing frame 31. At this time, the water pump inside the water tank 36 is activated, causing the water in the water tank 36 to be drawn into the two return pipes 38. The two return pipes 38 then introduce the water into the distribution pipe 37, and subsequently, the water in the distribution pipe 37 flows into the spray nozzle. Inside the water head 39, there are several water spray heads 39, which are fixedly installed on the top of the first processing frame 31 and the second processing frame 32 respectively. Then, the water spray heads 39 will spray water onto the wet curtain 302. Subsequently, the hot air passing through the first processing frame 31 and the second processing frame 32 will hit the wet curtain 302. When the hot air passes through the wet curtain 302, the water on the surface of the wet curtain 302 evaporates and absorbs heat, and the air temperature drops. Then, the hot air will be converted into cold air and discharged from the tail end of the second processing frame 32, and re-enter the left cavity of the protective cover 1 to cool down the motor assembly 5.

[0044] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
