Description

Technical Field

[0001] This invention relates to the field of waste heat recovery and utilization technology, specifically to a heat dissipation device for waste heat recovery in electromechanical equipment distribution boxes. Background Technology

[0002] According to existing information, a waste heat recovery and heat dissipation device for electromechanical equipment distribution boxes is an energy-saving device specifically designed for electromechanical equipment distribution boxes. It aims to solve the problem of waste heat generated during the operation of the distribution box and improve energy utilization efficiency by recovering and utilizing this waste heat. In this way, the device can not only effectively reduce the temperature of the distribution box and ensure its normal operation, but also realize the reuse of waste heat, thereby achieving the purpose of energy conservation and emission reduction.

[0003] Existing authorized patents and existing equipment with the same or similar technologies still have the following problems in daily use:

[0004] When collecting waste heat from electrical equipment distribution boxes, the high temperature inside the distribution box creates a temperature difference with the outside air, resulting in high humidity inside the box. When extracting the hot air, moisture is also extracted. Traditional waste heat recovery devices cannot immediately replace and dry the moisture-absorbing components when they become saturated. Saturated dehumidifiers cannot effectively remove moisture from the air, causing the moisture in the hot and humid air to return to the distribution box and potentially affecting the electronic components inside.

[0005] Meanwhile, traditional waste heat recovery devices transport hot air through a single pipe for extended periods, and the extracted hot air contains dust and other substances. Over time, these dust and other substances settle on the inner wall of the pipe, accumulating deposits such as dust, scale, and corrosion products. These deposits reduce the pipe's flow capacity and increase fluid resistance. Summary of the Invention

[0006] The purpose of this application is to solve or at least alleviate the problems existing in the prior art.

[0007] To address the aforementioned shortcomings, the present invention provides the following technical solution: a heat dissipation device for waste heat recovery in an electromechanical equipment distribution box, comprising a waste heat recovery box body, a waste heat collection pipe fixedly connected to the waste heat recovery box body, the waste heat collection pipe penetrating the outer wall of the waste heat recovery box body, one end of the waste heat collection pipe extending to the outside of the waste heat recovery box body being connected to the electromechanical equipment distribution box, the portion of the waste heat collection pipe located inside the waste heat recovery box body comprising two pathways, a control component being provided on the waste heat recovery box body, and an auxiliary component being provided on the waste heat recovery box body;

[0008] The control component includes an installation and placement chamber, which is symmetrically distributed and fixedly connected to one end of the waste heat collection pipe away from the main body of the waste heat recovery box. The control component is used to dehumidify the received hot air through adsorbents, and to perform a sensor-based switching of adsorbents after the moisture adsorption capacity is full, while simultaneously performing drying treatment on the switched adsorbents.

[0009] The auxiliary component includes a second limiting plate, which is symmetrically distributed and fixedly connected to the inner wall of the waste heat recovery box body. The auxiliary component is used to switch the pipeline through which waste heat is collected as the amount of moisture collected increases.

[0010] Furthermore, the control component also includes rollers, which are symmetrically distributed and rotatably connected to the surfaces of the mounting and placement compartments that are close to each other, and a conveyor belt is driven to the surface of each pair of rollers.

[0011] Furthermore, each of the multiple conveyor belts has a first moisture-absorbing plate fixedly connected to its opposite side, and a fixed plate fixedly connected to the opposite side of the multiple conveyor belts in a symmetrical arrangement. Each of the two fixed plates has a second moisture-absorbing plate slidably connected to it. Each of the two second moisture-absorbing plates has a connecting plate fixedly connected to its opposite side away from the first moisture-absorbing plate, and the connecting plate is slidably connected to the fixed plate.

[0012] Furthermore, each of the two installation chambers is fixedly connected to a first limiting plate, and each of the two first limiting plates is provided with a sliding limiting groove. The connecting plate is slidably connected to the sliding limiting groove. Each of the two installation chambers is fixedly connected to a connecting pipe on the side away from the waste heat collection pipe, and each of the two connecting pipes is fixedly connected to a heat exchange chamber at the end away from the installation chamber.

[0013] Furthermore, both heat exchange chambers are fixedly connected to condenser tubes, both connecting pipes are fixedly connected to the condenser tubes, and both condenser tubes are fixedly connected to connecting pipes at their ends away from the connecting pipes. Both connecting pipes extend through the main body of the waste heat recovery box to the outside of the main body of the waste heat recovery box at their ends away from the condenser tubes. Both connecting pipes have diversion pipes that extend through their outer walls. Both diversion pipes are fixedly connected to the installation chamber at their ends away from the connecting pipes. Both connecting pipes are rotatably connected to fans.

[0014] Furthermore, a first bevel gear is fixedly connected to one of the rollers, a fixed block is fixedly connected to the inner wall of the waste heat recovery box, a second bevel gear is rotatably connected inside the fixed block, the second bevel gear meshes with the first bevel gear, a rotating circular plate is fixedly connected to the top of the second bevel gear, an eccentric slider is fixedly connected to the top of the rotating circular plate, a rotating rod is rotatably connected to the surface of the eccentric slider, and a sliding groove is provided on the rotating rod.

[0015] Furthermore, the auxiliary component also includes a rack, which is slidably connected inside the second limiting plate and rotatably connected to the rotating rod.

[0016] Furthermore, a control ball is rotatably connected inside the waste heat collection pipe, and a transmission gear is fixedly connected to the top of the control ball. The transmission gear meshes with a rack, and the control ball has two holes of the same size as the waste heat collection pipe. Compared with known prior art, the technical solution provided by this invention has the following beneficial effects:

[0017] 1. This device uses a conveyor belt to cause the moisture collected inside the first absorbent plate to condense into water droplets. The increased weight of the first absorbent plate causes it to move downwards due to gravity, which in turn drives the conveyor belt to rotate. This causes the second absorbent plate to move upwards along with the first absorbent plate, alternating with it to absorb moisture from the air entering the waste heat collection pipe. By relying on the change in gravity to replace the absorbent plates, the device is not affected by objective factors and is controlled solely by gravity. This reduces the complexity of mechanical structures and electronic control systems, lowering the failure rate. Furthermore, the gravity-based replacement mechanism makes it highly adaptable, allowing it to handle moisture from the hot air inside distribution boxes in various environments. The replacement of the absorbent plates also prevents the moisture from being returned to the distribution box after the first absorbent plate becomes saturated, thus avoiding any negative impact on the internal structure.

[0018] 2. This device, by setting up a diversion pipe, allows a portion of the gas that has undergone heat exchange between the liquid inside the condenser tube and the heat exchange chamber to return to the main body of the waste heat recovery box. This gas is then diverted through the diversion pipe and enters the installation chamber. The gas is blown along the diversion pipe to the surface of the moisture-absorbing plate, where it comes into contact with the moisture inside the replaced plate. The continuously flowing gas dries the moisture in the first moisture-absorbing plate. Because the device operates continuously, the gas flowing into the diversion pipe is also continuous. Furthermore, by utilizing the gas after heat exchange, no additional waste heat or pollutants are generated, helping to maintain good environmental conditions. In addition, using the gas after heat exchange for drying reduces dependence on external heat sources, thereby reducing energy consumption and improving overall energy efficiency.

[0019] 3. This device uses a rack and pinion mechanism. As the first and second moisture-absorbing plates are replaced, the rack and pinion slide due to the transmission of force. This causes the transmission gear to rotate, which in turn causes the control ball to rotate, thus altering the gas flow path within the distribution box. Another pipe handles waste heat and moisture. By periodically switching pipes, all pipes can evenly bear the flow and pressure of hot air, preventing premature wear or damage to any single pipe due to prolonged use. Even wear extends the service life of the entire piping system, and periodic pipe switching reduces deposit accumulation, keeps the pipes clean, and improves the efficiency of hot air transmission.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to embodiments.

[0036] This embodiment provides a waste heat recovery and cooling device for an electromechanical equipment distribution box, such as... Figures 1-10 As shown, the device includes a waste heat recovery box body 101, a waste heat collection pipe 102 fixedly connected to the waste heat recovery box body 101, the waste heat collection pipe 102 penetrates the outer wall of the waste heat recovery box body 101, one end of the waste heat collection pipe 102 extending to the outside of the waste heat recovery box body 101 is connected to the electromechanical equipment distribution box, the part of the waste heat collection pipe 102 located inside the waste heat recovery box body 101 has two passages, a control component 200 is provided on the waste heat recovery box body 101, and an auxiliary component 300 is provided on the waste heat recovery box body 101.

[0037] The control component 200 includes an installation and placement chamber 201, which is symmetrically distributed and fixedly connected to one end of the waste heat collection pipe 102 away from the main body 101 of the waste heat recovery box. The control component 200 is used to dehumidify the received hot air through adsorbents, and to perform a sensor-based switching of adsorbents after the moisture adsorption capacity is full, and to simultaneously perform drying treatment on the switched adsorbents.

[0038] The auxiliary component 300 includes a second limiting plate 301, which is symmetrically distributed and fixedly connected to the inner wall of the waste heat recovery box body 101. The auxiliary component 300 is used to switch the pipe through which the waste heat collection flows as the amount of moisture collected increases.

[0039] As a preferred embodiment of this example, Figures 6-7 As shown, the control component 200 also includes rollers 203, which are symmetrically distributed and rotatably connected to the surfaces of the mounting and placement bins 201 that are close to each other. A conveyor belt 202 is drivenly connected to the surface of each pair of rollers 203.

[0040] Multiple conveyor belts 202 are fixedly connected to first moisture-absorbing plates 204 on their opposite sides. The sides of the multiple conveyor belts 202 that are close to each other are symmetrically distributed and fixedly connected to fixed plates 205. Second moisture-absorbing plates 206 are slidably connected to both fixed plates 205. Connecting plates 207 are fixedly connected to the sides of both second moisture-absorbing plates 206 that are away from the first moisture-absorbing plates 204. The connecting plates 207 are slidably connected to the fixed plates 205.

[0041] As a preferred embodiment of this example, Figures 6-10 As shown, each of the two installation chambers 201 is fixedly connected to a first limiting plate 208, and each of the two first limiting plates 208 is provided with a sliding limiting groove 209. The connecting plate 207 is slidably connected to the sliding limiting groove 209. Each of the two installation chambers 201 is fixedly connected to a connecting pipe 210 on the side away from the waste heat collection pipe 102. Each of the two connecting pipes 210 is fixedly connected to a heat exchange chamber 211 at the end away from the installation chamber 201.

[0042] Condensing pipes 212 are fixedly connected to the interior of each of the two heat exchange chambers 211. Two connecting pipes 210 are fixedly connected to the condensing pipes 212. The ends of the two condensing pipes 212 away from the connecting pipes 210 are fixedly connected to the connecting pipes 213. The ends of the two connecting pipes 213 away from the condensing pipes 212 extend through the main body 101 of the waste heat recovery box and out of the main body 101 of the waste heat recovery box. Diversion pipes 222 are connected through the outer walls of the two connecting pipes 213. The ends of the two diversion pipes 222 away from the connecting pipes 213 are fixedly connected to the installation chamber 201. Fans 214 are rotatably connected inside the two connecting pipes 213.

[0043] As a preferred embodiment of this example, Figures 4-5 As shown, a first bevel gear 215 is fixedly connected to one of the rollers 203. A fixing block 221 is fixedly connected to the inner wall of the waste heat recovery box body 101. A second bevel gear 216 is rotatably connected inside the fixing block 221. The second bevel gear 216 meshes with the first bevel gear 215. A rotating circular plate 217 is fixedly connected to the top of the second bevel gear 216. An eccentric slider 218 is fixedly connected to the top of the rotating circular plate 217. A rotating rod 220 is rotatably connected to the surface of the eccentric slider 218. A sliding groove 219 is provided on the rotating rod 220.

[0044] Compared with existing equipment of the same technology and similar technology, the following effects are achieved: by replacing the absorbent plate itself based on the gravity change, it is not affected by objective factors and is controlled only by the gravity change. This reduces the complexity of mechanical structure and electronic control system, lowers the failure rate, and by replacing the absorbent plate, it can prevent the moisture in the hot air from being unable to be absorbed after the absorbent plate is saturated, and promote the moisture to be transported back to the distribution box with the flow of gas.

[0045] At other levels, this embodiment also provides a heat dissipation device for waste heat recovery in electromechanical equipment distribution boxes, such as... Figure 5 As shown, the auxiliary component 300 also includes a rack 302, which is slidably connected to the inside of the second limiting plate 301, and the rack 302 is rotatably connected to the rotating rod 220;

[0046] As a preferred embodiment of this example, Figure 3 As shown, a control ball 304 is rotatably connected inside the waste heat collection pipe 102. A transmission gear 303 is fixedly connected to the top of the control ball 304. The transmission gear 303 meshes with the rack 302. Two holes of the same size as the waste heat collection pipe 102 are opened on the control ball 304.

[0047] Compared with existing equipment using the same technology or similar technologies, this system achieves the following effect: by periodically switching pipelines, all pipelines can be evenly subjected to the flow and pressure of hot air, thereby preventing premature wear or damage to any particular pipeline due to long-term use. Even wear can extend the service life of the entire pipeline system.

[0048] The complete working principle and process described above are as follows:

[0049] When the electrical distribution box of the electromechanical equipment operates for a long time, it generates a lot of heat due to the large number of electronic components inside. The operator holds the main body 101 of the waste heat recovery box and connects the waste heat collection pipe 102 to the distribution box. This allows the heat inside the distribution box to be drawn into the main body 101 by a cooling fan installed on the distribution box. Because of the temperature difference between the inside and outside of the distribution box, the humidity content of the air inside the distribution box increases. When the heat is extracted, moisture is also drawn out along with the hot air. This hot air then flows through the waste heat collection pipe 102 into the installation chamber 201. Due to the initial position of the first moisture-absorbing plate 204, it can process the moisture in the hot air entering the waste heat collection pipe 102. As the moisture absorbed by the first moisture-absorbing plate 204 increases, it becomes affected by the condensation of water droplets formed by the accumulation of moisture inside. Figure 6 As shown, move downwards;

[0050] Since the conveyor belt 202 is fixedly connected to the first moisture-absorbing plate 204, when the first moisture-absorbing plate 204 moves downward, the roller 203 rotates as the first moisture-absorbing plate 204 moves downward. Since the fixed plate 205 is fixedly connected to the conveyor belt 202, when the conveyor belt 202 rotates, the fixed plate 205 moves upward as the roller 203 rotates. The second moisture-absorbing plate 206 is slidably connected to the fixed plate 205. When the fixed plate 205 moves upward, the fixed plate 205 drives the second moisture-absorbing plate 206 to move upward synchronously. The connecting plate 207 is fixedly connected to the second moisture-absorbing plate 206. When the second moisture-absorbing plate 206 moves upward, the second moisture-absorbing plate 206 drives the connecting plate 207 to move upward synchronously. The connecting plate 207 is slidably connected to the sliding limiting groove 209. When the connecting plate 207 moves upward, the connecting plate 207 slides inside the sliding limiting groove 209.

[0051] like Figure 8 As shown, due to the shape of the sliding limiting groove 209, when the connecting plate 207 slides to the middle of the sliding limiting groove 209, the connecting plate 207 is pushed to the right by the shape of the sliding limiting groove 209 and moves a certain distance. At this time, the second moisture-absorbing plate 206, which was originally horizontal with the first moisture-absorbing plate 204, moves to the right as the connecting plate 207 moves to the right, causing the first moisture-absorbing plate 204 and the second moisture-absorbing plate 206 to become misaligned. As the connecting plate 207 continues to move upward, as... Figure 8 As shown, the connecting plate 207 moves to the left along the trajectory of the sliding limit groove 209, thereby pushing the second moisture-absorbing plate 206 to move away from the fixed plate 205. Due to the influence of gravity, the first moisture-absorbing plate 204 slides down to the bottom of the installation and placement chamber 201 and exchanges with the second moisture-absorbing plate 206. By relying on the gravity change of the first moisture-absorbing plate 204 to replace itself, it is not affected by objective factors and is only controlled by the gravity change, which reduces the complexity of mechanical structure and electronic control system and reduces the failure rate.

[0052] Furthermore, due to the shape of the sliding limit groove 209, the first moisture-absorbing plate 204 and the second moisture-absorbing plate 206 will not come into contact during the replacement process. At this time, the hot air that has been filtered by the first moisture-absorbing plate 204 enters the condenser tube 212 through the connecting pipe 210. Due to the low temperature of the liquid inside the heat exchange chamber 211, the hot air entering the condenser tube 212 exchanges heat with the liquid inside the heat exchange chamber 211, which lowers the temperature of the hot air inside the condenser tube 212. After cooling, the air enters the connecting pipe 213 along the condenser tube 212. Since the fan 214 is rotatably connected to the connecting pipe 213 and is electrically controlled to rotate, the airflow speed is accelerated and the air is guided. Since the diversion pipe 222 is fixedly connected to the connecting pipe 213, some of the cooling gas entering the connecting pipe 213 will enter the installation chamber 201 through the diversion pipe 222.

[0053] The gas entering the installation chamber 201 dries the replaced first moisture-absorbing plate 204, carrying away the moisture inside the first moisture-absorbing plate 204 through air circulation. As gas continuously enters the installation chamber 201, the gas inside the installation chamber 201 gradually fills up, affecting the installation chamber 201. The gas that has exchanged moisture is discharged through the holes at the bottom of the installation chamber 201 to prevent gas from remaining inside the installation chamber 201 and hindering the drying process of the first moisture-absorbing plate 204. The remaining gas in the connecting pipe 213 is transported back to the main body of the waste heat recovery box 101 and the power distribution box to reduce the temperature inside the power distribution box. By utilizing the gas after heat exchange, the design flexibility is increased. Using the gas after heat exchange for drying can reduce the dependence on external heat sources, thereby reducing energy consumption and improving overall energy efficiency.

[0054] The first bevel gear 215 is fixedly connected to the roller 203. When the roller 203 rotates, the roller 203 drives the first bevel gear 215 to rotate synchronously. Since the first bevel gear 215 meshes with the second bevel gear 216, the first bevel gear 215 transmits the force generated by the rotation of the roller 203 to the second bevel gear 216, so that the second bevel gear 216 rotates with the rotation of the first bevel gear 215. The rotating circular plate 217 is fixedly connected to the second bevel gear 216. When the second bevel gear 216 rotates, the rotating circular plate 217 rotates with the rotation of the second bevel gear 216. The eccentric slider 218 is fixedly connected to the rotating circular plate 217. When the rotating circular plate 217 rotates, the eccentric slider 218 rotates with the rotation of the rotating circular plate 217. The rotating rod 220 is rotatably connected to the eccentric slider 218. When the eccentric slider 218 rotates, it slides inside the rotating rod 220. The rack 302 is rotatably connected to the rotating rod 220.

[0055] As the eccentric slider 218 gradually moves closer to the rack 302 along with the rotation of the rotating circular plate 217, it causes the rotating rod 220 to drive the rack 302 to move synchronously. Since the rack 302 is slidably connected to the second limiting plate 301, as... Figure 5 As shown, the movement trajectory of the rack 302 is restricted by the second limiting plate 301, allowing it to slide only forward and backward. This causes the rack 302 to be blocked by the second limiting plate 301 when the rotating rod 220 drives it to move, and the rotating rod 220 rotates and slides inside the second limiting plate 301. Since the transmission gear 303 meshes with the rack 302, when the rack 302 moves, the rack 302 drives the transmission gear 303 to rotate. The control ball 304 is fixedly connected to the transmission gear 303. When the transmission gear 303 rotates, the transmission gear 303 drives the control ball 304 to rotate synchronously. At this time, the holes on the surface of the control ball 304 change the pipes connected to it as the control ball 304 rotates, completing the switching of the hot air flow path. This allows all pipes to bear the flow and pressure of hot air evenly, thereby preventing a certain pipe from wearing out or being damaged prematurely due to long-term use.

[0056] When the second moisture-absorbing plate 206 is also affected by the water droplets formed by excessive moisture accumulation inside it and moves downward, the first moisture-absorbing plate 204 is gradually dried by the air introduced by the diversion pipe 222, which reduces its weight. During the downward movement of the second moisture-absorbing plate 206, it moves upward by the rotation of the conveyor belt 202, thus completing the replacement with the second moisture-absorbing plate 206.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
