Abstract

This invention discloses a water-cooling system for inverter housing structures, including a machine room, a cooling chamber, and a main heat dissipation duct. The top of the machine room is connected to the top of the cooling chamber via the main heat dissipation duct. Multiple inverters are arranged in the machine room, and the top of each inverter housing is connected to the main heat dissipation duct via a branch pipe. This invention achieves the goal of cooling the internal heat of the inverters by allowing it to flow back into the machine room after being cooled by the air. This ensures that the inverters in the machine room can maintain normal operation.

Simultaneously, it removes adhering dust and condensate, preventing the heat dissipation duct from being blocked and hindering proper heat dissipation.

Description

Technical Field

[0001] This invention relates to the field of cooling system technology, specifically a water-cooling system for inverter housing structures. Background Technology

[0002] Existing frequency converters are directly installed in industrial sites, so their use requires long-term heat dissipation.

[0003] In the prior art, such as the "Cooling System for Transformers" with Chinese Patent No. CN107887133A, a cooling jacket is included. A bimetallic strip is installed on the inner wall of the cooling jacket, and the bimetallic strip includes an active strip and a passive strip. A water supply tank is connected to the outside of the cooling jacket. The water supply tank includes a windward side and a leeward side. Several air inlets are arranged side by side on the windward side, and several air outlets are arranged side by side on the leeward side. The diameter of the air inlets is 2 to 3 times the diameter of the air outlets. A metal conical tube is connected between the air inlets and the air outlets. A circulating water pipe is connected between the water supply tank and the cooling jacket. A water pump is installed on the circulating water pipe. The water pump, the active strip, and the passive strip form a closed loop.

[0004] However, in the existing technology, when using circulating water cooling technology to dissipate heat from transformers, after long-term use, not only will a large amount of condensate be generated on the heat sink of the circulating water cooling mechanism, but also impurities and dust blown in by the air duct will stick to it. Over time, this will block the ventilation gaps between the heat sinks, affecting heat transfer and thus reducing heat dissipation efficiency. In addition, a large amount of untreated condensate will accumulate at the cooling mechanism, which can easily lead to short circuits or corrosion of the metal structure. Summary of the Invention

[0005] The purpose of this invention is to provide a water cooling system for inverter housing structures to solve the problems mentioned in the background art, where, after long-term use of the circulating water cooling mechanism for transformer heat dissipation, not only does a large amount of condensate form on the heat sink, but also impurities and dust blown in by the air duct adhere to it, which accumulate over time and block the ventilation gaps between the heat sink, affecting heat transfer and thus reducing heat dissipation efficiency.

A driving wheel is movably inserted into the inner side of the transmission belt, and a motor is clamped at the bottom end of the driving wheel.

[0011] Preferably, a mounting bracket is fixedly attached to one side of the motor, and the mounting bracket and the lifting frame are fixedly installed by bolts.

[0012] Preferably, both ends of the limiting rod and the lead screw are welded with locking blocks, and each of the folded cleaning sheets includes an elastic silicone rod, the inner side of which is fitted with a folded sponge sheet.

[0013] Preferably, the top rod and the bottom rod are provided with multiple rotating grooves, and the two ends of the elastic silicone rod are fixedly installed with rotating shafts, which are rotatably installed with the rotating grooves.

[0014] Preferably, a water-blocking block is fixedly installed on the inner side of the bottom of the inclined cooling duct, and a condensate collection tank is fixedly inserted into the outer side of the bottom of the inclined cooling duct.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, when the ambient temperature exceeds a preset threshold, the high-temperature air inside each inverter is drawn into the main cooling duct through the branch pipe of the cooling duct and introduced into the inclined cooling duct. The water cooling mechanism absorbs the heat in the high-temperature airflow. After absorbing heat, the water in the water supply pipe flows back into the water storage tank through the return pipe, thereby always keeping the surface of the heat dissipation blade assembly lower than the temperature of the high-temperature airflow, and always cooling the airflow. The cooled airflow flows back into the machine room through the air outlet window, keeping the air in the machine room from getting too hot, so that the inverters in the machine room can maintain normal operation.

[0018] 2. In this invention, the condensate generated on the heat dissipation blade assembly will flow down along the inner wall of the inclined cooling air duct and be blocked by the water blocking block to be collected at the top opening of the condensate collection tank. When the air humidity exceeds the preset threshold of the humidity sensor, the second motor will be started to wind up the sling through the winding reel, thereby raising the hanger to the outlet of the inclined cooling air duct for blocking. This allows the air discharged into the machine room to be dried by the water-absorbing cotton column, thereby reducing the humidity in the machine room. This not only drains the generated condensate but also automatically regulates the humidity in the machine room, avoiding the problem of damage to electrical components caused by water accumulation or excessive air humidity.

[0019] 3. In this invention, once the motor starts, it will drive the lead screw to rotate sequentially through the drive wheel, transmission belt and driven wheel, so that the top rod and bottom rod move away from each other. At this time, the multiple elastic silicone rods and folded sponge sheets between the top rod and bottom rod will be stretched, thereby performing wiping work in the gap of the heat dissipation blade assembly, wiping away the adhering dust and condensate, and avoiding the problem of the heat dissipation air duct being blocked and unable to dissipate heat normally.

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.

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As shown: A water-cooling system for inverter housing structure includes a machine room 1, a cooling chamber 2, and a main heat dissipation duct 5. The top of the machine room 1 is connected to the top of the cooling chamber 2 via the main heat dissipation duct 5. Multiple inverters 3 are arranged in the machine room 1, and the top of the housing of each inverter 3 is connected to the main heat dissipation duct 5 via a branch pipe 4 of the heat dissipation duct. A temperature sensor 6 and a humidity sensor 7 are fixedly installed in the machine room 1. An intake fan 8 is installed inside one end of the main heat dissipation duct 5. A lifting frame 12 is arranged in the cooling chamber 2, and a lifting frame 12 is fixedly installed on its top. The inclined cooling duct 9 and the water-cooling mechanism 10 are configured. The top of the inclined cooling duct 9 is connected to the main heat dissipation duct 5, and the interior of the inclined cooling duct 9 is fixedly installed at one end of the water-cooling mechanism 10. An air outlet window 15 is fixedly installed at the bottom of the inclined cooling duct 9. The water-cooling mechanism 10 includes a water storage tank 101, a water pump 102, a return pipe 103, a water supply pipe 105, and multiple heat dissipation blade assemblies 107. The top of the water storage tank 101 is connected to the return pipe 103, and the bottom of the water storage tank 101 is connected to the water supply pipe 105. The water supply pipe 105 is connected to the water pump 102. 02 is connected to the return pipe 103, and both the water supply pipe 105 and the return pipe 103 are inserted into the interior of multiple heat dissipation blade groups 107. A dust removal assembly 24 is movably installed on the outside of the heat dissipation blade group 107. The temperature sensor 6 monitors the ambient temperature in the machine room 1 in real time. When the ambient temperature exceeds the preset threshold, the suction fan 8 starts, drawing the high-temperature air inside each inverter 3 into the main heat dissipation duct 5 through the heat dissipation duct branch pipe 4, and then guiding it into the inclined cooling duct 9 in the cooling chamber 2. After the water pump 102 of the water cooling mechanism 10 starts, it will... Cooling water in the water tank 101 is continuously introduced into the water supply pipe 105. When passing through the inside of the heat dissipation blade assembly 107, it absorbs the heat from the high-temperature airflow. After absorbing heat, the water in the water supply pipe 105 flows back into the water tank 101 through the return pipe 103, thus keeping the surface of the heat dissipation blade assembly 107 lower than the temperature of the high-temperature airflow and always cooling the airflow. The cooled airflow then flows back into the machine room 1 through the air outlet 15, keeping the air temperature in the machine room 1 from becoming too high and ensuring that the frequency converter 3 in the machine room 1 can maintain normal operation.

[0032] according to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, an air outlet 11 is provided at the bottom of one side of the inclined cooling air duct 9. A blower 104 is installed at one end of the water pump 102, and the output end of the blower 104 is directly facing the bottom of the heat dissipation blade assembly 107. A fixed base 106 is fixedly installed at the bottom of the blower 104. Each heat dissipation blade assembly 107 includes two outer shells 170. Multiple blades 171 are evenly fixed between the two outer shells 170, and a water supply pipe 105 is inserted into the outside of each blade 171. After the blower 104 is started, it will blow airflow to the bottom of the heat dissipation blade assembly 107 through the air outlet 11, thereby accelerating the high-temperature airflow at the top of the heat dissipation blade assembly 107 to be discharged quickly through the inclined cooling air duct 9.

[0033] Example 2

[0034] according to Figure 1 , Figure 6 , Figure 7 As shown, the dust removal assembly 24 includes two top rods 240, two bottom rods 242, and multiple connecting rods 241. The two top rods 240 are fixedly connected by the two connecting rods 241, and the two bottom rods 242 are fixedly connected by the other two connecting rods 241. Multiple folded cleaning blades 234 are movably installed between the top rods 240 and the bottom rods 242. A limit rod 244 is movably inserted into one end of the top rod 240 and the bottom rod 242, and a lead screw 246 is threaded to the other end of the top rod 240 and the bottom rod 242. A driven wheel 247 is fixedly installed on the outside of the lead screw 246, and a transmission belt 248 is sleeved on the outside of the driven wheel 247. A drive wheel 249 is movably inserted into the inside of the transmission belt 248, and a motor 250 is snapped into the bottom end of the drive wheel 249. A mounting bracket 251 is fixedly attached to the outside of the motor 250, and the mounting bracket 251 is fixedly installed to the lifting frame 12 by bolts. The limit rod 244 and the lead screw 246 are both welded with locking blocks 245. Each folded cleaning sheet 234 includes an elastic silicone rod 260, and a folded sponge sheet 261 is locked to the inside of the elastic silicone rod 260. After the motor 250 of the dust removal assembly 24 is started, it will drive the lead screw 246 to rotate through the drive wheel 249, the transmission belt 248 and the driven wheel 247, so that the top rod 240 and the bottom rod 242 move away from each other. At this time, the multiple elastic silicone rods 260 and the folded sponge sheet 261 between the top rod 240 and the bottom rod 242 will be stretched, thereby performing wiping work in the gap of the heat dissipation blade assembly 107 to remove the adhering dust and condensate.

[0035] Multiple rotating grooves 263 are provided on the top rod 240 and the bottom rod 242. The two ends of the elastic silicone rod 260 are fixedly installed with rotating shafts 262, and the rotating shafts 262 are rotatably installed with the rotating grooves 263. The first stop block 265 is fixedly installed on both sides of the rotating groove 263, and the second stop block 264 is fixedly installed on the rotating shaft 262. When the folded sponge sheet 261 wipes in the gap of the heat dissipation blade assembly 107, it will be blown by the airflow in the air duct after unfolding. In the gap of the heat dissipation blade assembly 107, it will shake around the rotating shaft 262 as the axis of rotation, thereby accelerating the cleaning of the impurities adhering to the heat dissipation blade assembly 107. The first stop block 265 and the second stop block 264 are set to prevent the folded sponge sheet 261 from automatically rotating after being blown and getting stuck and blocking the air duct, or to increase the friction wear between it and the heat dissipation blade assembly 107, and limit its rotation to only within 180 degrees.

[0036] Example 3

[0037] according to Figure 1 As shown, a water-blocking block 16 is fixedly installed on the inner side of the bottom of the inclined cooling air duct 9, and a condensate collection tank 17 is fixedly inserted into the outer side of the bottom of the inclined cooling air duct 9. A water guide pipe 19 is connected to one side of the bottom end of the condensate collection tank 17, and a one-way valve 18 is connected to the other side of the bottom end of the condensate collection tank 17. A drying assembly 20 is movably inserted into the bottom end of the inclined cooling air duct 9. The drying assembly 20 includes a hanger 201. A water-absorbing cotton column 202 is rotatably connected to the inner side of the hanger 201, and a sling 203 is fixedly installed on the top of the hanger 201. A winding reel 205 is wound around the sling 203, and a motor 204 is rotatably connected to the winding reel 205. The condensate generated on the heat dissipation blade assembly 107 will flow along the inclined cooling air duct 9. The water flows down the inner wall and is blocked by the water blocking block 16 to the top opening of the condensate collection tank 17, where it is collected and discharged through the water guide pipe 19 into the water exchange pipe 13. When the air humidity exceeds the preset threshold of the humidity sensor 7, the start motor 204 will reel in the sling 203 through the reel 205, thereby raising the hanger 201 to the outlet of the inclined cooling air duct 9 for blocking. This allows the air discharged into the machine room 1 to be dried by the water-absorbing cotton column 202, thereby reducing the humidity in the machine room 1. After the water-absorbing cotton column 202 is saturated with water, the water droplets inside it will fall to the bottom and flow into the condensate collection tank 17 through the one-way valve 18, and finally be discharged through the water guide pipe 19 into the water exchange pipe 13.

[0038] A water pipe 19 is connected to a water exchange pipe 13, and a suction pump 14 is fixedly installed on the water exchange pipe 13 for quickly replacing the cooling water in the top water storage tank 101. A ventilation fan 23 is fixedly installed on the top of the machine room 1 to accelerate air circulation in the machine room 1 and help maintain normal temperature. A maintenance ladder 21 is fixedly installed in the cooling chamber 2, and a maintenance door 22 is movably installed on the top of the lifting frame 12 to facilitate maintenance workers to perform maintenance work on the water cooling mechanism 10 in the cooling chamber 2. Multiple air inlets 30 are evenly opened at the bottom of the inverter 3 housing, and a second ventilation fan 31 is connected to the top of the inverter 3 housing. A protective cover 32 is fixedly installed on the outer side of the top of the inverter 3 housing, and a transfer pipe 33 is connected to the top of the protective cover 32. The top of the transfer pipe 33 is connected to the bottom of the heat dissipation air duct branch pipe 4, which facilitates the rapid extraction of heat from inside the inverter 3 along with the air through the second ventilation fan 31 to the main heat dissipation air duct 5 for cooling.

[0039] The operating method and working principle of this device are as follows: When the ambient temperature exceeds the preset threshold, the intake fan 8 starts, drawing the high-temperature air inside each inverter 3 into the main cooling duct 5 through the cooling duct branch pipe 4, and then guiding it into the inclined cooling duct 9 in the cooling chamber 2. After the water pump 102 of the water cooling mechanism 10 starts, it continuously guides the cooling water in the water storage tank 101 into the water delivery pipe 105. When passing through the inside of the heat dissipation blade assembly 107, it absorbs the heat in the high-temperature airflow. After absorbing heat, the water in the water delivery pipe 105 flows back into the water storage tank 101 through the return pipe 103. At the same time, after the blower 104 starts, it blows airflow to the bottom of the heat dissipation blade assembly 107 through the air outlet 11, thereby accelerating the high-temperature airflow at the top of the heat dissipation blade assembly 107 to be quickly discharged through the inclined cooling duct 9. The surface of the heat dissipation blade assembly 107 is always kept below the temperature of the high-temperature airflow, which can always cool the airflow passing through. The cooled airflow will flow back into the machine room 1 through the air outlet 15, keeping the air temperature in the machine room 1 from being too high, so that the inverter 3 in the machine room 1 can maintain normal operation.

[0040] Meanwhile, after the motor 250 of the dust removal assembly 24 is started, it will drive the lead screw 246 to rotate through the drive wheel 249, the transmission belt 248 and the driven wheel 247, so that the top rod 240 and the bottom rod 242 move away from each other. At this time, the multiple elastic silicone rods 260 and the folded sponge sheet 261 between the top rod 240 and the bottom rod 242 will be stretched, thereby performing wiping work in the gap of the heat dissipation blade assembly 107 to remove the adhering dust and condensate.

[0041] In addition, when the air humidity exceeds the preset threshold of the humidity sensor 7, the second motor 204 will be started to wind up the sling 203 through the winding reel 205, thereby raising the hanger 201 to the outlet of the inclined cooling air duct 9 for shielding. This allows the air discharged into the machine room 1 to be dried by the water-absorbing cotton column 202, thereby reducing the humidity in the machine room 1. After the water-absorbing cotton column 202 is saturated with water, the water droplets inside it will fall to the bottom and flow into the condensate collection tank 17 through the one-way valve 18, and finally be discharged into the water exchange pipe 13 through the water guide pipe 19.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
