Description

Technical Field

[0001] This invention belongs to the technical field of power quality management equipment, and specifically discloses a power quality management device based on gallium nitride. Background Technology

[0002] Gallium nitride (GaN) is primarily used in power quality management in power electronic devices, particularly in the improvement of switching power supplies and power semiconductor devices, thereby enhancing power conversion efficiency and stability. As a wide-bandgap semiconductor material, GaN possesses high electron mobility, high breakdown electric field, and fast switching characteristics, making it outstanding in high-frequency, high-efficiency, and high-temperature power electronic devices. A power quality management module is a device used to improve power quality in a power supply system; it can detect and correct various power quality problems in the power system, such as voltage fluctuations, current harmonics, and voltage sags / amplitudes. Below are the components of a common outdoor power quality management module: power quality monitoring, filters, voltage regulators, power factor correction, overvoltage / undervoltage protection, and data logging and communication.

[0003] Current power quality management devices generate significant heat during operation due to the operation of their internal components. While gallium nitride (GaN) exhibits high-temperature resistance and can operate stably in high-temperature environments, and GaN components significantly reduce the size and weight of passive devices, improving overall system efficiency, this high-frequency operation also leads to higher heat generation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a cooling module, the internal components of the casing can be effectively cooled, providing a good working environment for the internal components. The support frame reduces the amount of material used, and the honeycomb structure increases the support strength. The support frame also reduces operating costs. The top plate absorbs the heat generated by the electrical components of the gallium nitride structure during operation and dissipates it through the heat-conducting block and filler via heat pipes. During this process, the coolant dissipates heat from the heat pipes, carrying away the absorbed heat through the flow of the coolant.

[0015] 2. The cooling module is designed to directly contact the heat source of the gallium nitride device, minimizing thermal resistance; the heat dissipation layer quickly eliminates hot spots; the main heat dissipation layer provides a large heat dissipation area, which can fully unleash the high-frequency and high-power potential of the gallium nitride device, allowing for higher power density designs, extremely high space utilization, and significantly reducing the volume of the heat dissipation system.

[0016] 3. By setting auxiliary components, when there is no external coolant supply, the flow direction of the coolant can be changed by changing the position of the regulating block, so that it can be changed from external cooling to internal circulation. This prevents it from over-relying on external cooling and allows it to use internal circulation in conjunction with the fan for forced circulation. This makes the device suitable for different environments and improves its applicability. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-11 The power quality management device based on gallium nitride application shown includes a housing 1, a cooling module 2 is provided inside the housing 1, a connection window is provided on one side of the housing 1, and a removable baffle 3 is provided on the surface of the housing 1, and the baffle 3 is used to block the connection window. The cooling module 2 includes a connecting shell 202 fixedly connected to the inner wall of the outer shell 1. A connecting block 201 is fixedly connected to one side of the connecting shell 202, and a controller 206 is embedded in the other side of the connecting block 201. A groove is formed on the surface of the connecting block 201. A cooling component is provided inside the connecting shell 202. A connecting cavity 217 is formed inside the connecting block 201. Two symmetrically distributed mounting cavities 215 are formed inside the connecting cavity 217. A fan 214 is provided inside the mounting cavity 215. An air inlet slot 205 communicating with the mounting cavity 215 is formed on the surface of the connecting block 201. An exhaust slot 216 evenly distributed and communicating with the outside is formed on the inner wall of the mounting cavity 215. An auxiliary component 22 is provided inside the connecting cavity 217. Two connecting components 21 are provided on the other side of the connecting block 201.

[0022] By starting the fan 214, outside air can pass through the air inlet slot 205 and be introduced into the interior of the connecting cavity 217, and then discharged through the exhaust slot 216.

[0023] like Figures 1-11 As shown, the cooling assembly includes a mounting block 204 fixedly connected to the top of the connecting shell 202. A top plate 203 is fixedly connected to the top of the mounting block 204. The top plate 203 is an aluminum metal component. The top of the mounting block 204 has evenly distributed connecting grooves, and the interior of the connecting grooves is filled with heat-conducting blocks 207.

[0024] The connecting shell 202 has a support frame 208 inside, which is honeycomb shaped. The surface of the support frame 208 has evenly distributed connecting holes 209 and water guiding holes 210. The mounting block 204 has evenly distributed heat-conducting pipes 211 inside. The upper end of the heat-conducting pipes 211 is connected to the connecting groove. The heat-conducting pipes 211 are filled with filler. The filler and the heat-conducting block 207 are made of thermally conductive silicone grease. The lower end of the heat-conducting pipes 211 extends into the interior of the support frame 208.

[0025] By introducing coolant into the interior of the connecting shell 202, the coolant can flow inside the connecting shell 202 through the connecting hole 209 and the water guide hole 210. See [link / details for specific flow direction]. Figure 6 The support frame 208 reduces the amount of material used, and the honeycomb structure increases the support strength. The top plate 203 absorbs the heat generated by the electrical components of the gallium nitride component during operation and dissipates it through the heat-conducting block 207 and the filler via the heat-conducting pipe 211. During this process, the coolant dissipates heat through the heat-conducting pipe 211 and carries away the absorbed heat through the flow of the coolant.

[0026] like Figures 1-11As shown, one side of the connecting shell 202 is connected to an inlet pipe 212 and an outlet pipe 213. The other ends of the inlet pipe 212 and the outlet pipe 213 are connected to a connecting pipe 230. The other end of the connecting pipe 230 is connected to the connecting assembly 21. A fixing block 223 is provided in the middle of one of the connecting pipes 230. Both ends of the fixing block 223 are provided with docking cavities 224 that are connected to the connecting pipe 230. A water flow sensor 231 is provided inside the connecting pipe 230. A docking block 219 is fixedly connected to the top of the fixing block 223. The surface of the docking block 219 is provided with two connecting channels 222 that are connected to the two docking cavities 224 respectively.

[0027] The upper end of the docking block 219 extends into the interior of the groove and is threadedly connected to the separation shell 229. The inner wall of the separation shell 229 is fixedly connected to the filter cylinder 220. The bottom of the filter cylinder 220 is connected to the inlet pipe 218. The other end of the inlet pipe 218 is connected to one of the connecting channels 222. The bottom of the separation shell 229 is provided with a drain hole 221 that is connected to the other connecting channel 222.

[0028] The connecting pipe 230 is used for the flow of coolant. The coolant is injected into the interior of the support frame 208 through the water inlet pipe 212 and flows through the connecting hole 209 and the water guide hole 210. Finally, it is discharged through the water outlet pipe 213 and then discharged through another connecting pipe 230. The water flow sensor 231 is used to detect whether there is water flowing through the connecting pipe 230. When there is no water flowing through, it transmits a signal to the controller 206. During the process of coolant entering the inlet pipe 212 through the connecting pipe 230, it can enter the connected channel 222 through one of the docking chambers 224, and be injected into the filter cartridge 220 through the inlet pipe 218. After filtering the impurities inside the coolant, it is injected into the other connected channel 222 through the drain hole 221, and simultaneously injected into the inlet pipe 212 through the other docking chamber 224 and the connecting pipe 230.

[0029] like Figures 1-11 As shown, the top of another connecting pipe 230 is connected to a fixed pipe 228, the upper end of the fixed pipe 228 is connected to a storage shell 225, an adjusting plate 227 is slidably connected to the inner wall of the storage shell 225, and a first spring 226 is fixedly connected between the top of the adjusting plate 227 and the inner wall of the storage shell 225.

[0030] Water discharged through the outlet pipe 213 and the connecting pipe 230 can be introduced into the storage shell 225 through the fixed pipe 228. During this process, the water pressure can push the adjusting plate 227 to squeeze the first spring 226. As the coolant absorbs heat and expands, the water pressure will increase, which can further push the adjusting plate 227 to compress the first spring 226. This can adapt to coolants with different temperature differences and avoid pipe breakage caused by coolant pressure expansion.

[0031] like Figures 1-11 As shown, the auxiliary component 22 includes a water pump 2209 disposed inside the connecting cavity 217. The water pump 2209 has a guide pipe 2208 connected to both its outlet and inlet ends. The guide pipe 2208 is distributed in a serpentine pattern. The other end of the guide pipe 2208 is connected to an adjusting shell 2201. The adjusting shell 2201 passes through the connecting pipe 230 and is connected to the connecting pipe 230. The surface of the adjusting shell 2201 has two through holes for connecting the connecting pipe 230.

[0032] An adjusting block 2204 is slidably connected to the inner wall of the adjusting shell 2201. The surface of the adjusting block 2204 has a through hole 2206 coaxially arranged with the connecting pipe 230. The surface of the adjusting block 2204 has an inlet channel 2205. One end of the inlet channel 2205 is coaxially arranged with the adjusting shell 2201, and the other end of the inlet channel 2205 is located on the side of the adjusting block 2204. A fixing ring 2203 is fixedly connected to the inner wall of the adjusting shell 2201. A third spring 2207 is fixedly connected between the fixing ring 2203 and the adjusting block 2204. An electromagnet 2202 located below the fixing ring 2203 is provided inside the adjusting shell 2201. The adjusting block 2204 is a magnetic metal material component.

[0033] Under normal conditions, the third spring 2207 can maintain the position of the adjusting block 2204, allowing the coolant to flow normally along the connecting pipe 230 through the through hole 2206. When the water flow sensor 231 detects no water flow, it can transmit a signal to the controller 206 and activate the electromagnet 2202. Under the action of the electromagnet 2202, the adjusting block 2204 can be attracted, causing the adjusting block 2204 to move down and compress the third spring 2207, thereby changing the position of the through hole 2206. This allows the coolant discharged through the outlet pipe 213 to enter the guide pipe 2208 after entering the channel 2205. By activating the fan 214, the airflow can be used to force the coolant flowing inside the guide pipe 2208 to dissipate heat, thereby achieving the effect of internal coolant circulation. This allows the device to circulate and dissipate coolant in outdoor conditions or when the cooling station cannot supply water, ensuring the normal operation of the device.

[0034] like Figures 1-11As shown, the connecting assembly 21 includes an installation pipe 2101 that communicates with the connecting pipe 230. A connecting pipe 2104 is fixedly connected to the inner wall of the other end of the installation pipe 2101 away from the installation pipe 2101. The inner wall of the connecting pipe 2104 is provided with internal threads. A fixing plate 2102 is fixedly connected to the inner wall of the installation pipe 2101. The surface of the fixing plate 2102 is provided with evenly distributed water passage holes. A guide rod 2106 is between the fixing plate 2102 and the connecting pipe 2104. The other end of the guide rod 2106 passes through the fixing plate 2102. A sealing block 2105 for sealing the inside of the connecting pipe 2104 is fixedly connected to the other end of the guide rod 2106. A second spring 2103 is fixedly connected between the sealing block 2105 and the fixing plate 2102.

[0035] The external liquid supply pipe can be inserted into the inside of the connector 2104 via a threaded connection, and push the sealing block 2105 to move. During this process, the guide rod 2106 can be driven to gradually pass through the fixed plate 2102 while compressing the second spring 2103. The surface of the connecting end of the liquid supply pipe is provided with external threads, and the drain hole is located on the outside, so the flow of coolant will not be affected by the sealing block 2105. The coolant discharged through the external liquid supply pipe can flow normally through the water passage and the fixed plate 2102. After the external liquid supply pipe is removed, the guide rod 2106 and the sealing block 2105 can be reset under the action of the second spring 2103, thereby sealing the connector 2104 and preventing the coolant from flowing out.

[0036] Working principle: Under normal use, the external liquid supply pipe can be inserted into the inside of the connecting pipe 2104 via a threaded connection, pushing the sealing block 2105 to move. During this process, the guide rod 2106 gradually passes through the fixing plate 2102 while compressing the second spring 2103. The connecting end surface of the liquid supply pipe is provided with external threads, and the drain hole is located on the outside, so the flow of coolant is not affected by the sealing block 2105. The coolant discharged through the external liquid supply pipe can flow normally through the water passage and the fixing plate 2102. After the external liquid supply pipe is removed, the guide rod 2106 and the sealing block 2105 are reset under the action of the second spring 2103, thus sealing the connecting pipe 2104 and preventing the coolant from flowing out. The introduced coolant can flow through the connecting pipe 230 and through the water inlet pipe 2 12. Entering the interior of the connecting shell 202, during this process, the top plate 203 can absorb the heat generated during the operation of the electrical components of the gallium nitride component, and dissipate it through the heat-conducting block 207 and the filler through the heat-conducting pipe 211. During this process, the coolant can dissipate heat through the heat-conducting pipe 211 and carry out the absorbed heat through the flow of the coolant. The coolant after heat exchange is introduced into the connecting pipe 230 through the outlet pipe 213. The water discharged can be introduced into the interior of the storage shell 225 through the fixed pipe 228. During this process, the water pressure can push the adjusting plate 227 to squeeze the first spring 226. As the heat is absorbed, the coolant expands due to heat, and the water pressure increases, which can further push the adjusting plate 227 to compress the first spring 226. This can adapt to coolants with different temperature differences and avoid the situation of pipe breakage due to coolant pressure expansion. Simultaneously, when the water flow sensor 231 detects no water flow, it can transmit a signal to the controller 206 and activate the electromagnet 2202. Under the action of the electromagnet 2202, the adjusting block 2204 can be attracted, causing the adjusting block 2204 to move down and compress the third spring 2207, thereby changing the position of the through hole 2206. This allows the coolant discharged through the water outlet pipe 213 to enter the guide pipe 2208 after entering the channel 2205. By activating the fan 214, the airflow can be used to force the coolant flowing inside the guide pipe 2208 to dissipate heat, thereby achieving the effect of internal coolant circulation. This allows the device to circulate and dissipate coolant in outdoor conditions or when the cooling station cannot supply water, ensuring the normal operation of the device.
