Description

Technical Field

[0001] This invention relates to the technical field of control cabinets, and in particular to an environmentally friendly intelligent dust removal control cabinet and control method. Background Technology

[0002] Electrical control cabinets are a core component of industrial automation systems, integrating a large number of power components, controllers, and execution modules. In dust removal systems in industries such as power, metallurgy, cement, and chemicals, dust removal control cabinets operate under harsh conditions of high load and high dust levels for extended periods. On the one hand, the electronic components inside the cabinet (such as programmable logic controllers, switching power supplies, relays, and pulse drive modules) generate a large amount of heat during long-term continuous operation. On the other hand, dust in the field environment can easily enter through gaps in the cabinet or ventilation holes, leading to short circuits or poor contact of components.

[0003] To address the aforementioned issues, existing technologies have provided relevant improvements. For example, patent application CN201610225494.2 discloses an "intelligent cleaning electrical control cabinet," which uses an internal dust concentration detector and an ion dust removal device to generate ion wind to neutralize static electricity in the dust and discharges the dust through an exhaust fan, thereby achieving intelligent cleaning of the control cabinet's interior. This solution addresses, to some extent, the problems of low efficiency in manual dust removal and the ease with which external dust can be introduced when using ordinary fans, thus playing a positive role in maintaining the cleanliness of the cabinet.

[0004] However, in practical engineering applications, the aforementioned existing technologies still have the following significant limitations: First, there is a conflict between heat dissipation and cleaning functions: This solution mainly relies on the "exhaust fan" for heat exchange, which is a forced air cooling. Although the fan can promote airflow, when the external ambient temperature is high or the dust concentration is high, simply increasing the air volume not only has limited heat dissipation efficiency, but will also continuously introduce external hot air or fine dust into the cabinet, increasing the burden on the ion dust removal device, and even accelerating dust accumulation when the ion device fails.

[0005] Secondly, there is a lack of targeted thermal management for high-power components: In modern intelligent dust removal control cabinets, components such as pulse valve drive modules and transformers generate concentrated heat. Existing technologies only dissipate heat through overall ventilation, which cannot efficiently transfer or replace local heat sources, easily leading to heat accumulation inside the cabinet and affecting the stability of the core controller.

[0006] Therefore, how to construct an efficient, automatic, and environmentally friendly heat dissipation mechanism while ensuring the cleanliness (dust removal) inside the control cabinet, especially addressing the contradictory issues of "heat accumulation" and "dust intrusion" in high-power dust removal control cabinets, has become a technical challenge that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the present invention provides an environmentally friendly intelligent dust removal control cabinet and control method.

[0008] This invention discloses an environmentally friendly intelligent dust removal control cabinet, comprising a cabinet body, a cabinet door, heat dissipation holes, and a cooling fan. The cabinet door is hinged at the front end of the cabinet body, heat dissipation holes are located on the right side of the cabinet body, and a cooling fan is located on the left side of the cabinet body. The cabinet also includes: The liquid cooling system, installed on the main body of the control cabinet, is used to cool the interior of the cabinet. In use, the operator activates the cooling fan, allowing cool outside air to enter the control cabinet. Hot air inside the cabinet is exhausted through ventilation holes, thus replacing the hot air inside and achieving air cooling. Simultaneously, the liquid cooling system absorbs heat from inside the cabinet and transfers it to the outside. Through both air and liquid cooling, the internal temperature of the control cabinet is reduced, improving cooling efficiency.

[0009] Preferably, the liquid cooling assembly includes a first liquid storage tank, a second liquid storage tank, a 230, a delivery pipe, a pump body, a suction pipe, a delivery pipe, heat sinks, a serpentine tube, a heat dissipation component, a first switch assembly, and a second switch assembly. The second liquid storage tank is located at the top of the control cabinet body, and the first liquid storage tank is located at the rear of the control cabinet body via a bracket. A U-shaped tube is installed inside the control cabinet body. A delivery pipe is installed at the output end of the second liquid storage tank, and the output end of the delivery pipe is connected to the input end of the first switch assembly. The output end of the U-shaped tube is connected to the output end of the first switch assembly. The outer wall of the U-shaped tube... The system is equipped with multiple heat sinks. A pump body is located at the bottom of the first liquid storage tank. A suction pipe is installed at the pump body's input end, connecting to the bottom of the first liquid storage tank. A delivery pipe is installed at the pump body's output end, connecting to the input end of the second liquid storage tank. The output end of a U-shaped tube extends to the outside of the control cabinet body and connects to the input end of a serpentine tube, which in turn connects to the input end of the first liquid storage tank. A second switch assembly is installed on the first liquid storage tank, electrically connected to the pump body. A heat dissipation assembly is installed between the control cabinet body and the first liquid storage tank. During operation, coolant is present in tanks 1 and 2, as well as inside the U-shaped tube. The coolant inside the U-shaped tube absorbs heat from the control cabinet body through multiple heat sinks. Switches 1 and 2 remain closed, causing the coolant temperature to rise. This increased temperature opens switch 1, allowing the low-temperature coolant in tank 2 to enter the U-shaped tube through the delivery pipe. The low-temperature coolant displaces the high-temperature coolant inside the U-shaped tube using the principle of communicating vessels. When the U-shaped tube is full of low-temperature coolant, the low-temperature coolant... When switch component one closes, the high-temperature coolant enters the first reservoir through a serpentine tube. As the high-temperature coolant is delivered through the serpentine tube, it is cooled by the heat dissipation components. As the coolant level in the first reservoir rises, the increased coolant level activates switch component two, thereby starting the pump. The pump, with the cooperation of the suction pipe and the delivery pipe, delivers the low-temperature coolant from the first reservoir back to the second reservoir. When the coolant level in the first reservoir drops, switch component two closes, thus stopping the pump.

[0010] Preferably, the No. 1 switch assembly includes a housing, a No. 1 optical bar, an airbag, a baffle, and a through hole. The housing is located inside the main body of the control cabinet. The output end of the infusion tube is connected to the input end of the housing, and the input end of the U-shaped tube is connected to the output end of the housing. A No. 1 optical bar is longitudinally fixed inside the housing. The baffle is slidably connected to two sets of No. 1 optical bars. A through hole is provided on the No. 1 optical bar. An airbag is located between the bottom end of the baffle and the bottom end of the housing. The interior of the U-shaped tube and the interior of the housing are filled with low-temperature coolant. The low-temperature coolant reduces the volume of the airbag, thereby allowing the baffle to... The valve moves downwards, and the through hole and the output end of the infusion tube are staggered. The baffle seals the output end of the infusion tube. When the coolant inside the U-shaped tube and the shell absorbs heat from the inside of the control cabinet and the temperature rises, the high temperature coolant causes the airbag to expand, thereby raising the baffle with the help of the first light bar. The through hole and the output end of the infusion tube are then aligned, and the low temperature coolant inside the first storage tank enters the shell and the U-shaped tube through the infusion tube, realizing the replacement of coolant. This process is repeated to achieve automatic replacement of coolant inside the U-shaped tube. The operation is simple and convenient.

[0011] Preferably, the heat dissipation assembly includes a support frame, a housing, a fan, and a flow switch. A support frame is installed between the control cabinet body and the first liquid storage tank. Multiple housings are mounted on the support frame, and each housing houses a fan. A flow switch is installed on the serpentine tube, and the flow switch is electrically connected to the fan. When the low-temperature coolant in the second liquid storage tank enters the U-shaped tube for replacement, the high-temperature coolant inside the U-shaped tube is transported to the first liquid storage tank through the serpentine tube. The coolant flows inside the serpentine tube, and the flow switch detects the coolant flow, activating multiple flow switches. These flow switches cool the outer wall of the serpentine tube with cold air, thus cooling the high-temperature coolant inside. Once the high-temperature coolant inside the U-shaped tube has been replaced, the coolant flow inside the serpentine tube stops, the flow switch no longer detects flowing coolant, and the multiple fans stop rotating. This achieves energy saving and consumption reduction by having multiple fans cool the high-temperature coolant inside the serpentine tube when it is flowing, even when there is high-temperature coolant flowing inside, thus cooling the coolant.

[0012] Preferably, the second switch assembly includes a second optical bar, a float, a lifting plate, a first bracket, a photoelectric signal transmitter, a second bracket, a photoelectric signal receiver, and a shielding plate. Two sets of second optical bars are longitudinally arranged inside the first liquid storage tank. A set of floats is movably mounted on each set of second optical bars. A lifting plate is arranged between the two sets of floats. A shielding plate is located at the top of the lifting plate, extending to the top of the first liquid storage tank and slidably connected to it. A first bracket and a second bracket are respectively arranged at the top of the first liquid storage tank. A photoelectric signal transmitter is located at the top of the first bracket, and a photoelectric signal receiver is located at the top of the second bracket. The shielding plate is positioned between the photoelectric signal transmitter and the photoelectric signal receiver. The receiver is electrically connected to the pump body. When the high-temperature coolant inside the U-tube is replaced by the coolant in the No. 1 storage tank, the coolant level in the No. 1 storage tank rises. This causes the float, guided by the No. 2 optical bar, to raise the lifting plate. The lifting plate then raises the shielding plate, which blocks the photoelectric signal emitted by the photoelectric signal transmitter. The photoelectric signal receiver cannot receive the photoelectric signal emitted by the photoelectric signal transmitter, and the pump body starts. This allows the coolant inside the No. 1 storage tank to enter the No. 1 storage tank temporarily through the suction pipe and delivery pipe. When the coolant level in the No. 1 storage tank drops, the shielding plate descends, the photoelectric signal receiver resumes receiving the photoelectric signal emitted by the photoelectric signal transmitter, and the pump body stops.

[0013] Preferably, it also includes a No. 1 drain pipe and a No. 1 drain valve. A No. 1 drain pipe is installed at the bottom of the No. 1 storage tank, and a No. 1 drain valve is installed on the No. 1 storage tank. When it is necessary to replace the coolant inside the No. 1 storage tank, the No. 1 drain valve is opened, so that the coolant inside the No. 1 storage tank is discharged through the No. 1 drain pipe, thereby improving the convenience of operation.

[0014] Preferably, it also includes a second drain pipe and a second drain valve. The bottom end of the second drain valve is connected to the input end of the second drain pipe, and the output end of the second drain pipe extends to the outside of the control cabinet body. The second drain valve is installed on the second drain pipe. Opening the second drain valve allows the cold liquid inside the U-shaped tube to be drained through the second drain pipe, improving the ease of operation.

[0015] Preferably, it also includes a base, with a base provided at the bottom of the control cabinet body; the base provides stable support for the control cabinet body and improves the stability of the support.

[0016] Preferably, it also includes a protective cover. The top of the No. 1 liquid storage tank is equipped with a protective cover, and the No. 1 bracket, photoelectric signal transmitter, No. 2 bracket and photoelectric signal receiver are all inside the protective cover. The protective cover provides anti-collision protection for the photoelectric signal transmitter and photoelectric signal receiver, thereby improving safety.

[0017] A control method for an environmentally friendly intelligent dust removal control cabinet includes the following steps: The first step is for staff to start the cooling fan, allowing the low-temperature outside air to enter the control cabinet body through the cooling fan, while the hot air inside the control cabinet body is exhausted through the heat dissipation holes, thus achieving air-cooled ventilation. The second step is that, at the same time, the liquid cooling component operates automatically. When the internal temperature of the control cabinet body rises, the coolant in the U-shaped tube absorbs heat and enhances heat exchange through the heat sink. The high-temperature coolant causes the air bag to expand, thereby opening the No. 1 switch component. The low-temperature coolant in the No. 2 storage tank enters the U-shaped tube through the liquid delivery pipe by gravity, replacing and discharging the high-temperature coolant. The third step is that when the displaced high-temperature coolant flows through the serpentine tube, the flow switch detects the flow signal and starts the fan to force the serpentine tube to cool down. The cooled coolant then enters the No. 1 storage tank for temporary storage. Step 4: When the liquid level in the No. 1 storage tank rises to the set value, the float moves the baffle plate to rise, triggering the photoelectric signal interruption, thereby starting the pump. The pump pumps the coolant in the No. 1 storage tank back to the No. 2 storage tank through the liquid extraction pipe and the delivery pipe, completing a complete liquid cooling cycle. Step 5: When the temperature inside the cabinet decreases, the temperature of the coolant in the U-shaped tube drops, the air bladder contracts, the No. 1 switch component is closed, the coolant stops replacing, there is no flow in the serpentine tube, the flow switch is turned off, the fan stops, and the pump automatically stops after the liquid level drops, thus realizing a fully automatic, on-demand intelligent liquid cooling process.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: When in use, the operator starts the cooling fan, so that the low-temperature air from the outside enters the control cabinet body through the cooling fan. The hot air inside the control cabinet body is exhausted through the heat dissipation holes, thereby replacing the high-temperature air inside the control cabinet body and achieving air cooling. At the same time, the liquid cooling component performs liquid cooling operation on the inside of the control cabinet body. The liquid cooling component absorbs the heat inside the control cabinet body and transfers the heat to the outside of the control cabinet body. Through air cooling and liquid cooling, the inside of the control cabinet body is cooled in two ways, improving the cooling efficiency. Attached Figure Description

[0021] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0022] Example 1 like Figures 1 to 10As shown, an environmentally friendly intelligent dust removal control cabinet of the present invention includes a control cabinet body 101, a cabinet door 102, a heat dissipation hole 103, and a heat dissipation fan 104. The cabinet door 102 is movably provided at the front end of the control cabinet body 101 via a hinge. A heat dissipation hole 103 is provided at the right end of the control cabinet body 101, and a heat dissipation fan 104 is provided at the left end of the control cabinet body 101. A base 105 is provided at the bottom end of the control cabinet body 101 for stable support. The above components together constitute the basic frame structure of the control cabinet. It should be noted that the heat dissipation fan 104 is an axial flow fan, and its installation position is opposite to the heat dissipation hole 103 so that the airflow can pass through the interior of the cabinet. In the embodiment of the present invention, this basic structure provides an installation carrier and basic ventilation path for the subsequent liquid cooling components. As a preferred option, a coarse filter cotton can be added to the air inlet of the heat dissipation fan 104 to initially intercept large-particle dust. It should be understood that the filter cotton is a conventional consumable in the prior art, and its specific thickness and mesh size can be selected according to the dust concentration on site. Furthermore, the present invention also includes a liquid cooling assembly, which is installed on the control cabinet body 101 for cooling the interior of the control cabinet body 101. This liquid cooling assembly includes a first liquid storage tank 201, a second liquid storage tank 202, a U-shaped tube 203, a delivery pipe 204, a pump body 205, a suction pipe 206, a delivery pipe 207, a heat sink 208, a serpentine tube 209, a heat dissipation component, a first switch assembly, and a second switch assembly. The second liquid storage tank 202 is located at the top of the control cabinet body 101, and the first liquid storage tank 201 is located at the rear end of the control cabinet body 101 via a bracket. A U-shaped tube 203 is installed inside the control cabinet body 101. The U-shaped tube 203, as the main heat-absorbing component, is preferably made of copper to improve thermal conductivity. A delivery pipe 204 is installed at the output end of the second liquid storage tank 202, and the output end of the delivery pipe 204 is connected to the input end of the first switch assembly. The output end of the U-shaped tube 203 is also connected to the output end of the first switch assembly. Multiple sets of heat dissipation fins 208 are installed on the outer wall of the U-shaped tube 203 to increase the heat exchange area with the air inside the cabinet. A pump body 205 is installed at the bottom of the first liquid storage tank 201, and a suction pipe 206 is installed at the input end of the pump body 205, which is connected to the bottom end of the first liquid storage tank 201. The output end of the pump body 205 is... A delivery pipe 207 is provided, with its output end connected to the input end of the second liquid storage tank 202. The output end of the U-shaped pipe 203 extends to the outside of the control cabinet body 101 and connects to the input end of the serpentine pipe 209. The output end of the serpentine pipe 209 connects to the input end of the first liquid storage tank 201. A second switch assembly is installed on the first liquid storage tank 201, and the second switch assembly is electrically connected to the pump body 205. A heat dissipation assembly is installed between the control cabinet body 101 and the first liquid storage tank 201. It should be noted that the serpentine pipe 209 is an exposed moving part (actually a stationary liquid circuit part, but its outer surface is in constant contact with air). To prevent dust accumulation from affecting heat dissipation efficiency, a protective cover with ventilation holes should be detachably installed on the outside of the serpentine tube 209. This protective cover is made of perforated steel plate and is fixed to the inner wall of the control cabinet body 101 with bolts for regular cleaning. In addition, the pump body 205 is an electrical component, and its wiring port should use a waterproof sealing joint to prevent moisture intrusion. In this solution, the liquid cooling component adopts a modular design concept. The first liquid storage tank 201 and the second liquid storage tank 202 are installed independently for easy maintenance and replacement. At the same time, the U-shaped tube 203 and the heat sink 208 form an integrated heat absorption unit, which improves assembly efficiency and heat exchange consistency. Furthermore, the No. 1 switch assembly includes a housing 301, a No. 1 optical bar 302, an airbag 303, a baffle 304, and a through hole 305. The housing 301 is installed inside the control cabinet body 101. The output end of the infusion tube 204 is connected to the input end of the housing 301, and the input end of the U-shaped tube 203 is connected to the output end of the housing 301. The No. 1 optical bar 302 is fixedly installed longitudinally inside the housing 301. The baffle 304 is slidably connected to two sets of No. 1 optical bars 302. The No. 1 optical bar 302 is equipped with... An airbag 303 is provided between the bottom end of the baffle 304 and the bottom end of the housing 301, with a through hole 305. The airbag 303 contains a medium with a high coefficient of thermal expansion (such as ethanol or Freon). When the coolant inside the U-shaped tube 203 and the housing 301 absorbs heat from the inside of the control cabinet body 101 and its temperature rises, the high-temperature coolant causes the airbag 303 to expand, thereby pushing the baffle 304 upwards under the guidance of the first optical bar 302. The through hole 305... When the output end of the infusion tube 204 coincides with the output end, the low-temperature coolant inside the first storage tank 201 enters the housing 301 and U-shaped tube 203 through the infusion tube 204 to replace the coolant. After the low-temperature coolant enters, the airbag 303 contracts, causing the baffle 304 to move down and close the outlet of the infusion tube 204. It should be noted that the first light bar 302 and the baffle 304 are relatively moving parts. A self-lubricating graphite copper sleeve and a dustproof sealing ring should be installed between them to prevent dust from entering and causing jamming. In addition, the airbag 303 is at risk of aging and leakage when working at high temperature for a long time. As an alternative, a memory alloy spring can be used in conjunction with a temperature sensing plate to achieve the same temperature control opening function. The memory alloy spring deforms at the set temperature to push the baffle 304. This solution does not require a sealing medium and has a longer lifespan. In addition, the housing 301 is preferably made of cast aluminum and has heat dissipation fins on the outer surface to assist in heat dissipation and avoid the airbag 303 from malfunctioning due to excessive internal temperature. Furthermore, the heat dissipation assembly includes a support frame 401, a housing 402, a fan 403, and a flow switch 404. A support frame 401 is provided between the control cabinet body 101 and the first liquid storage tank 201. Multiple housings 402 are provided on the support frame 401, and a fan 403 is installed inside each housing 402. A flow switch 404 is provided on the serpentine tube 209, and the flow switch 404 is electrically connected to the fan 403. It is necessary to actively identify that the fan 403 is a rotating component that rotates continuously. Its bearing should be provided with a lubricating oil filling hole or a maintenance-free ceramic bearing should be used. In addition, the air inlet of the fan 403 should be provided with a metal protective mesh to prevent foreign objects from entering. In addition, the flow switch 404 is an electrical component, and its connection line with the controller should be shielded and wrapped with a corrugated tube to avoid electromagnetic interference. As a preferred solution, the fan 403 can be a temperature-controlled speed-regulating fan, that is, a temperature sensor is added to the drive circuit of the fan 403 so that its speed is automatically adjusted according to the surface temperature of the serpentine tube 209, thereby further reducing energy consumption. Furthermore, the second switch assembly includes a second optical bar 501, a float 502, a lifting plate 503, a first bracket 504, a photoelectric signal transmitter 505, a second bracket 506, a photoelectric signal receiver 507, and a shielding plate 508. Two sets of second optical bars 501 are longitudinally arranged inside the first liquid storage tank 201. A set of floats 502 is movably mounted on each set of second optical bars 501. A lifting plate 503 is arranged between the two sets of floats 502. A shielding plate 508 is provided at the top of the lifting plate 503, extending above the first liquid storage tank 201. The shielding plate 508 is slidably connected to the first liquid storage tank 201. The top of the tank 201 is equipped with a first bracket 504 and a second bracket 506. A photoelectric signal transmitter 505 is mounted on the top of the first bracket 504, and a photoelectric signal receiver 507 is mounted on the top of the second bracket 506. A shielding plate 508 is positioned between the photoelectric signal transmitter 505 and the photoelectric signal receiver 507. The photoelectric signal transmitter 505 and the photoelectric signal receiver 507 are electrically connected to the pump body 205. When the high-temperature coolant inside the U-shaped tube 203 is replaced by the coolant inside the first storage tank 201, the coolant level inside the first storage tank 201 rises. The float 502, guided by the second light bar 501, drives the lifting plate. When the lifting plate 503 rises, it causes the blocking plate 508 to rise, thus blocking the light signal emitted by the photoelectric signal transmitter 505. Unable to receive the signal, the photoelectric signal receiver 507 is activated, and the pump body 205 pumps the coolant from the first storage tank 201 back to the second storage tank 202. After the liquid level drops, the blocking plate 508 descends, the photoelectric signal is restored, and the pump body 205 stops. It should be noted that the photoelectric signal transmitter 505 and the photoelectric signal receiver 507 are electrical components exposed to the external environment and should be protected by a protective cover 509 for waterproofing and dustproofing. This protective cover 509 is made of transparent engineering plastic and has sealing strips at the seams. Meanwhile, since the float 502 is submerged in coolant for a long time, algae or scale may grow on its surface. Therefore, a smooth, corrosion-resistant polypropylene material should be selected, and a small amount of antibacterial agent should be added to the coolant. In addition, since the second light bar 501 and the float 502 are relatively moving parts, a self-lubricating bushing should be installed to reduce wear. As an alternative, an ultrasonic level sensor can be used to replace the float 502 and the photoelectric switch assembly. The ultrasonic level sensor measures the liquid level height non-contactly and directly outputs an electrical signal to control the pump body 205. This solution eliminates mechanical moving parts and improves reliability, but the cost is higher. In practical applications, the choice can be made according to the protection level requirements. Furthermore, the present invention also includes a first drain pipe 210 and a first drain valve 211. The first drain pipe 210 is provided at the bottom of the first liquid storage tank 201, and the first drain valve 211 is provided on the first liquid storage tank 201. This structure is used to periodically replace the coolant in the first liquid storage tank 201. Opening the first drain valve 211 allows the coolant to be discharged through the first drain pipe 210. It is important to note that the outlet end of the first drain pipe 210 should be equipped with a quick-connect connector and a matching sealing cap to prevent dust or insects from entering the pipeline when the coolant is not being discharged. Furthermore, the present invention also includes a second drain pipe 212 and a second drain valve 213. The bottom end of the second drain valve 213 is connected to the input end of the second drain pipe 212, and the output end of the second drain pipe 212 extends to the outside of the control cabinet body 101. The second drain valve 213 is installed on the second drain pipe 212. This structure is used to drain the coolant inside the U-shaped pipe 203 for maintenance or winter antifreeze. It is important to note that a manual air vent valve should be installed at the lowest point of the second drain pipe 212 to release air from the pipe when refilling coolant, so as to avoid air resistance affecting the replacement effect. In this embodiment, the operator first starts the cooling fan 104. Low-temperature outside air enters the control cabinet body 101 through the cooling fan 104. Hot air inside the control cabinet body 101 is exhausted through the heat dissipation holes 103, achieving air cooling and ventilation. Simultaneously, the liquid cooling component operates automatically: when the internal temperature of the control cabinet body 101 rises, the coolant in the U-shaped tube 203 absorbs heat and enhances heat exchange through the heat sink 208. The high-temperature coolant causes the airbag 303 to expand, thereby opening the first switch component. The low-temperature coolant in the second storage tank 202, under gravity, enters the U-shaped tube 203 through the infusion pipe 204, displacing and discharging the high-temperature coolant. When the displaced high-temperature coolant flows through the serpentine tube 209, the flow switch 404 detects the flow signal and starts the fan 403 to force air cooling of the serpentine tube 209. The cooled coolant then enters the first storage tank 201 for temporary storage. When the liquid level in the first storage tank 201 rises to the set value, the float 502 drives the baffle 508 to rise, triggering a photoelectric signal interruption and thus starting the pump 205. The pump 205 pumps the coolant in the first storage tank 201 back to the second storage tank 202 through the suction pipe 206 and the delivery pipe 207 to complete a complete liquid cooling cycle. When the temperature inside the cabinet decreases, the temperature of the coolant in the U-shaped tube 203 drops, the air bladder 303 contracts and closes the first switch assembly, the coolant replacement stops, there is no flow in the serpentine tube 209, the flow switch 404 disconnects, the fan 403 stops, and the pump 205 also automatically stops after the liquid level drops, thus realizing a fully automatic, on-demand intelligent liquid cooling process. During the entire operation, air cooling and liquid cooling work together, and the start-up, replacement, heat dissipation and return of the liquid cooling cycle are all automatically completed by thermodynamic and fluid dynamic principles without the need for additional logic controller intervention.

[0023] Example 2 The present invention provides an environmentally friendly intelligent dust removal control cabinet control method, which includes the following steps: First, the operator starts the cooling fan 104, so that the low temperature air from the outside enters the control cabinet body 101 through the cooling fan 104, and the hot air inside the control cabinet body 101 is exhausted through the heat dissipation hole 103 to achieve air cooling and ventilation. The second step is that, at the same time, the liquid cooling component operates automatically. When the internal temperature of the control cabinet body 101 rises, the coolant in the U-shaped tube 203 absorbs heat and enhances heat exchange through the heat sink 208. The high-temperature coolant causes the air bag 303 to expand, thereby opening the No. 1 switch component. The low-temperature coolant in the No. 2 liquid storage tank 202 enters the U-shaped tube 203 by gravity through the liquid delivery pipe 204, replacing and discharging the high-temperature coolant. Third step: When the displaced high-temperature coolant flows through the serpentine tube 209, the flow switch 404 detects the flow signal and starts the fan 403 to force the serpentine tube 209 to be cooled by air. The cooled coolant enters the first storage tank 201 for temporary storage. Step 4: When the liquid level in the No. 1 storage tank 201 rises to the set value, the float ball 502 drives the baffle plate 508 to rise, triggering the photoelectric signal interruption, thereby starting the pump body 205. The pump body 205 pumps the coolant in the No. 1 storage tank 201 back to the No. 2 storage tank 202 through the liquid extraction pipe 206 and the delivery pipe 207, completing a complete liquid cooling cycle. Step 5: When the temperature inside the cabinet decreases, the temperature of the coolant in the U-shaped tube 203 drops, the air bag 303 contracts, the No. 1 switch assembly is closed, the coolant stops replacing, there is no flow in the serpentine tube 209, the flow switch 404 is turned off, the fan 403 stops, and the pump body 205 automatically stops after the liquid level drops, thus realizing a fully automatic, on-demand intelligent liquid cooling process.

[0024] like Figures 1 to 10As shown, this invention discloses an environmentally friendly intelligent dust removal control cabinet and control method. During operation, the operator first starts the cooling fan 104, allowing low-temperature outside air to enter the control cabinet body 101 through the fan. Hot air inside the control cabinet body 101 is exhausted through the heat dissipation holes 103, achieving air cooling and ventilation. Simultaneously, the liquid cooling component operates automatically: when the internal temperature of the control cabinet body 101 rises, the coolant in the U-shaped tube 203 absorbs heat and enhances heat exchange through the heat sink 208. The high-temperature coolant causes the airbag 303 to expand, thereby opening the first switch component. The low-temperature coolant in the second storage tank 202, under gravity, enters the U-shaped tube 203 through the delivery pipe 204, displacing and discharging the high-temperature coolant. When the displaced high-temperature coolant flows through the serpentine tube 209, the flow switch 404 detects the flow signal and starts the fan 403 to force air cooling of the serpentine tube 209. The cooled coolant... The coolant is temporarily stored in the No. 1 storage tank 201. When the liquid level in the No. 1 storage tank 201 rises to the set value, the float 502 drives the baffle 508 to rise, triggering a photoelectric signal interruption and starting the pump body 205. The pump body 205 pumps the coolant in the No. 1 storage tank 201 back to the No. 2 storage tank 202 through the liquid extraction pipe 206 and the delivery pipe 207 to complete a complete liquid cooling cycle. When the temperature inside the cabinet decreases, the temperature of the coolant in the U-shaped tube 203 drops, the air bladder 303 contracts and closes the No. 1 switch assembly, the coolant replacement stops, there is no flow in the serpentine tube 209, the flow switch 404 disconnects, the fan 403 stops, and the pump body 205 also automatically stops after the liquid level drops. This realizes a fully automatic, on-demand intelligent liquid cooling process. During the entire operation, air cooling and liquid cooling work together, and the start-up, replacement, heat dissipation and return of the liquid cooling cycle are all automatically completed by thermodynamic and fluid dynamic principles without the need for additional logic controller intervention.

[0025] The main functions achieved by this invention are: First, the present invention uses a thermal expansion driven No. 1 switch assembly (airbag 303 and baffle 304 structure) to realize the temperature self-sensing replacement of coolant without any external sensors or programmable logic controllers, overcoming the technical prejudice that "liquid cooling system must rely on electric valve or solenoid valve in conjunction with temperature controller" that has long existed in the minds of those skilled in the art. Second, this invention organically combines air cooling and liquid cooling and uses flow switch 404 to enable the fan 403 to start on demand. Forced heat dissipation is only performed when there is high temperature coolant flowing in the serpentine tube 209, which avoids energy consumption and dust accumulation caused by long-term ineffective operation of fan 403. This "flow-heat dissipation" linkage mechanism has not been disclosed in existing dust removal control cabinets. Third, the present invention realizes the function of automatically starting and stopping the pump body 205 based on the liquid level through the second switch assembly (float 502 and photoelectric signal transmitter 505 / receiver 507), so that the coolant automatically resets after completing a complete "heat absorption-displacement-heat dissipation-return" cycle, forming a closed-loop self-maintaining system.

[0026] The present invention discloses an environmentally friendly intelligent dust removal control cabinet and control method. Its installation, connection, and setting methods are all common mechanical methods, and any method that achieves its beneficial effects can be implemented. The cooling fan 104, pump body 205, air bag 303, fan 403, flow switch 404, float 502, photoelectric signal transmitter 505, and photoelectric signal receiver 507 of the present invention are commercially available. Those skilled in the art only need to install and operate them according to the accompanying instruction manual, without requiring creative effort from those skilled in the art. For example, the pump body 205 can be a miniature DC diaphragm pump, and its control line can be directly connected to the relay output terminal of the photoelectric signal receiver 507. Furthermore, the photoelectric signal transmitter 505 and photoelectric signal receiver 507 can be through-beam photoelectric switches, with a DC power supply voltage of 24V, connected in parallel with the switching power supply inside the control cabinet body 101. The specific wiring method follows the principle of separating strong and weak currents and uses PVC cable trays. These are all existing technologies in the art and conform to the structural layout shown in the accompanying drawings.

[0027] Although embodiments of the present invention have been shown and described, it should be understood that the scope of protection of the present invention is not limited to the specific embodiments disclosed. Variations, modifications, substitutions, and modifications are permitted without departing from the principles of the present invention. For example: First, the airbag 303 in the No. 1 switch assembly can be replaced with a bimetallic strip temperature control mechanical structure. The bimetallic strip bends and deforms when the temperature changes, directly pushing the baffle 304 to achieve the same on / off function. Second, the heat-absorbing part of the U-tube 203 can be replaced with a plate heat exchanger to increase the heat exchange area and adapt to the internal space layout of different control cabinets. Third, the number of fans 403 can be increased or decreased between three and six groups according to the actual length of the serpentine tube 209 and the heat generation. The mounting bracket of the fan 403 can use elastic shock-absorbing pads to reduce vibration transmission. The scope of protection of the present invention is defined by the appended claims and their equivalents.

A control method for an environmentally friendly intelligent dust removal control cabinet, characterized in that, Includes the following steps: Step 1: The staff starts the cooling fan (104) so ​​that the low temperature air outside enters the control cabinet body (101) through the cooling fan (104) and the hot air inside the control cabinet body (101) is discharged through the heat dissipation hole (103) to achieve air cooling and ventilation. Second step: At the same time, the liquid cooling component operates automatically. When the internal temperature of the control cabinet body (101) rises, the coolant in the U-shaped tube (203) absorbs heat and enhances heat exchange through the heat sink (208). The high-temperature coolant causes the air bag (303) to expand, thereby opening the No. 1 switch component. The low-temperature coolant in the No. 2 storage tank (202) enters the U-shaped tube (203) by gravity through the liquid delivery pipe (204) to replace and discharge the high-temperature coolant. In the third step, when the displaced high-temperature coolant flows through the serpentine tube (209), the flow switch (404) detects the flow signal and starts the fan (403) to force the serpentine tube (209) to cool down. The cooled coolant then enters the first storage tank (201) for temporary storage. Step 4: When the liquid level in the No. 1 storage tank (201) rises to the set value, the float (502) drives the baffle (508) to rise, triggering the photoelectric signal interruption, thereby starting the pump body (205). The pump body (205) pumps the coolant in the No. 1 storage tank (201) back to the No. 2 storage tank (202) through the liquid extraction pipe (206) and the delivery pipe (207), completing a complete liquid cooling cycle.
