Description

Technical Field

[0001] This invention belongs to the technical field of heat dissipation equipment for power distribution cabinets, specifically relating to a heat dissipation auxiliary component and a power distribution cabinet using the component. Background Technology

[0002] Distribution cabinets should be made of non-combustible materials. Open-type distribution boards can be installed in production areas and offices with low risk of electric shock. Enclosed cabinets should be installed in processing workshops, foundries, forging plants, heat treatment plants, boiler rooms, and woodworking shops where the risk of electric shock is high or the working environment is poor. In hazardous work areas with conductive dust or flammable and explosive gases, sealed or explosion-proof electrical facilities must be installed. The components inside the distribution cabinet generate a large amount of heat during operation, and the components themselves are quite sensitive to high temperatures. If the internal temperature of the distribution cabinet is too high, it will seriously affect the operational stability and service life of the power distribution equipment. Generally, exhaust fans are installed on the distribution cabinet to achieve cooling. However, when the fan is working, external dust, oil, and harmful gases will also enter the distribution cabinet and be attracted by static electricity on the circuit board surface. Over time, this will corrode the components and wiring, and also affect heat dissipation. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art by providing a heat dissipation auxiliary component and a power distribution cabinet using the component.

[0004] This invention provides the following technical solution:

[0005] A heat dissipation auxiliary component and a power distribution cabinet using the component include a slide rail installed inside the power distribution cabinet, a mounting panel slidably connected to the slide rail, an inclined rod fixedly installed between the symmetrically arranged mounting panels, and a cooling fan installed on the inclined rod.

[0006] The cabinet door consists of an upper door panel, a lower door panel, and a pivot. The upper and lower door panels are rotatably connected to the pivot.

[0007] The sealing assembly includes a sealing plate that is hinged to each other and a rubber seal mounted on the sealing plate. The sealing assembly is installed on the upper door panel and the lower door panel. The sealing assembly is used to prevent rainwater and dust from entering the power distribution cabinet from the connection between the upper door panel and the lower door panel.

[0008] Furthermore, the cabinet door is movably mounted on the power distribution cabinet via hinges, facilitating the installation and removal of the cabinet door. The upper door panel is provided with a receiving groove one, and the lower door panel is provided with a receiving groove two. One end of the receiving groove one and the receiving groove two extends into the shaft body, and the receiving groove one and the receiving groove two are connected. Connecting blocks are movably installed in the receiving groove one and the receiving groove two, and the two ends of the sealing plate are fixedly installed on the corresponding connecting blocks.

[0009] Furthermore, the connecting block is provided with a shaft, the bottom end of the sealing plate is hinged to the shaft, the connecting block is provided with a groove to facilitate the rotation of the sealing plate around the shaft, and the rubber seal is installed on the inner side of the sealing plate. When the included angle between the upper door panel and the lower door panel is greater than 90° and less than 180°, the rubber seal and the sealing plate prevent foreign objects on the outside of the cabinet door from entering the power distribution cabinet.

[0010] Furthermore, the number of cooling fans does not exceed three, and multiple ventilation arc covers are provided on both sides of the power distribution cabinet to facilitate the circulation of air inside and outside the power distribution cabinet.

[0011] Furthermore, the cabinet door is provided with an exhaust groove, and a connecting shaft is rotatably connected inside the exhaust groove. A gear is fixedly installed at one end of the connecting shaft, and a gear chain is installed on the gear. A through hole for accommodating the gear chain is provided between adjacent exhaust grooves to facilitate the gears rotating together. A motor for driving one of the connecting shafts to rotate is installed at one end of the connecting shaft, and a baffle is fixedly installed on the connecting shaft, and the baffle is located inside the exhaust groove.

[0012] Furthermore, the cabinet door is provided with a first groove, and the power distribution cabinet body is provided with a second groove corresponding to the first groove. The first groove and the second groove are provided with sealing elements for sealing the opening and closing of the cabinet door and the power distribution cabinet body.

[0013] Furthermore, a liquid storage tank is installed at the bottom of the power distribution cabinet. A water outlet pipe and a water inlet pipe are installed on one side of the liquid storage tank. The liquid storage tank is filled with coolant. Multiple vents are provided between the liquid storage tank and the power distribution cabinet. A moisture-absorbing component is provided in each vent. A sealing cap is movably connected to the top of each vent. The vent is located on one side of the mounting panel.

[0014] Furthermore, a temperature sensor is installed inside the power distribution cabinet, and the motor, cooling fan, and temperature sensor are electrically connected.

[0015] The beneficial effects of this invention are:

[0016] 1. The cabinet door is equipped with a heat dissipation vent that can automatically close. The vent is used to monitor the temperature changes inside the distribution cabinet in real time. When necessary, the vent will open to dissipate heat. Otherwise, the vent will be closed to prevent dust and water damage.

[0017] 2. A liquid storage tank is installed at the bottom of the power distribution cabinet. The internal coolant provides cooling protection and prevents the internal heat from accumulating and becoming difficult to dissipate due to weather conditions.

[0018] 3. Since most distribution cabinets have a large internal space, and the components are small and almost impossible to stack, resulting in wasted space, movable mounting panels are installed inside the distribution cabinet to make full use of the internal space.

[0019] 4. A sealing component is installed at the connection between the upper and lower door panels to prevent rainwater and dust from entering the power distribution cabinet from the connection between the upper and lower door panels, thus protecting the components inside the power distribution cabinet.

[0025] Example 1

[0026] like Figures 1-4 As shown, a heat dissipation auxiliary component and a power distribution cabinet using the component are disclosed. The power distribution cabinet 1 contains a cooling fan 7. The cabinet door 2 consists of an upper door panel 201, a lower door panel 202, and a shaft 203. The upper door panel 201 and lower door panel 202 are rotatably connected to the shaft 203. The upper door panel 201 and lower door panel 202 can swing around the shaft 203 at a certain angle. The upper door panel 201 and lower door panel 202 have two working modes: when the included angle between the upper door panel 201 and lower door panel 202 is a flat angle, they function as a cabinet door. The cabinet is mounted on the power distribution cabinet via a hinge 4. On cabinet 1, when the included angle between the upper door panel 201 and the lower door panel 202 is greater than 90° and less than 180°, it serves as the top cover of the distribution cabinet 1. In this case, the distribution cabinet is used indoors. The cabinet door 2 is provided with a groove 209, and the distribution cabinet 1 is provided with a groove 102 corresponding to the groove 209. The groove 209 and the groove 102 are provided with sealing elements for sealing the opening and closing of the cabinet door 2 and the distribution cabinet 1, so as to ensure that when the distribution cabinet 1 is closed, external dust and oil will not enter the distribution cabinet 1.

[0027] The cabinet door 2 is provided with an exhaust groove 215, and a connecting shaft 211 is rotatably connected within the exhaust groove 215. A gear 213 is fixedly installed at one end of the connecting shaft 211, and a gear chain 214 is installed on the gear 213. A through hole for accommodating the gear chain 214 is provided between adjacent exhaust grooves 215 to facilitate the simultaneous rotation of all gears 213. A motor 212 for driving one of the connecting shafts 211 is installed at one end of the connecting shaft 211. A baffle 210 is fixedly installed on the connecting shaft 211, and the baffle 210 is located within the exhaust groove 215. A temperature sensor 9 is installed inside the electrical cabinet 1. The motor 212, the cooling fan 7, and the temperature sensor 9 are electrically connected. The temperature sensor 9 monitors the temperature inside the electrical cabinet 1. When the temperature inside the electrical cabinet 1 reaches the set value, the motor 212 and the cooling fan 7 work. At this time, the connecting shaft 211 connected to the motor 212 rotates. Through the gear 213 and the gear chain 214, a chain drive is formed. The baffle 210 fixedly installed on the connecting shaft 211 rotates at a certain angle, which, together with the cooling fan 7 inside the electrical cabinet 1, sends the high-temperature gas inside the electrical cabinet 1 out of the electrical cabinet.

[0028] The sealing assembly 206 includes a sealing plate 217 hinged to each other and a rubber seal 207 mounted on the sealing plate 217. The sealing assembly 206 is mounted on the upper door panel 201 and the lower door panel 202. The sealing assembly 206 is used to prevent rainwater and dust from entering the power distribution cabinet 1 from the connection between the upper door panel 201 and the lower door panel 202.

[0029] Cabinet door 2 is movably mounted on the power distribution cabinet 1 via hinge 4, facilitating the installation and removal of cabinet door 2. The upper door panel 201 is provided with a receiving groove 216, and the lower door panel 202 is provided with a receiving groove 204. One end of the receiving groove 216 and the receiving groove 204 extends into the shaft 203, and the receiving groove 216 and the receiving groove 204 are connected. Connecting blocks 205 are movably installed in the receiving groove 216 and the receiving groove 204. Both ends of the sealing plate 217 are fixedly installed on the corresponding connecting blocks 205.

[0030] The connecting block 205 has a shaft 208 inside, and the bottom end of the sealing plate 217 is hinged to the shaft 208. The connecting block 205 has a groove to facilitate the rotation of the sealing plate 217 around the shaft 208. The rubber seal 207 is installed on the inner side of the sealing plate 217. When the included angle between the upper door panel 201 and the lower door panel 202 is greater than 90° and less than 180°, the rubber seal 207 and the sealing plate 217 prevent foreign objects on the outside of the cabinet door 2 from entering the power distribution cabinet 1.

[0031] When the included angle between the upper door panel 201 and the lower door panel 202 is a flat angle, one end of the sealing plate 217 swings around the shaft 208 until the sealing plate 217 is located in the receiving groove 1 216 and the receiving groove 204. The inner side of the sealing plate 217 is provided with a groove to accommodate the rubber seal 207. When the sealing plate 217 is located in the receiving groove 1 216 and the receiving groove 204, the rubber seal 207 is located in the groove. At this time, the sealing plate 217 seals the connection between the upper door panel 201 and the lower door panel 202. When the included angle between the upper door panel 201 and the lower door panel 202 is greater than 90° and less than 180°, the minimum included angle between the upper door panel 201 and the lower door panel 202 is as follows: Figure 2 As shown, at this time, the rubber seals 207 on the two hinged sealing plates are tightly fitted together, and the sealing purpose is achieved by the tightly fitted rubber seals 207 and sealing plates 217.

[0032] Example 2

[0033] like Figures 1-4 As shown, a liquid storage tank 3 is installed at the bottom of the power distribution cabinet 1. A water outlet pipe 301 and a water inlet pipe 305 are installed on one side of the liquid storage tank 3. The liquid storage tank 3 is filled with coolant 302. Multiple vent holes 303 are provided between the liquid storage tank 3 and the power distribution cabinet 1. A moisture-absorbing component 304 is provided in the vent hole 303. A sealing cover 306 is movably connected to the top of the vent hole 303. The vent hole 303 is located on one side of the mounting panel 5.

[0034] When the temperature monitored by temperature sensor 9 remains at the set value for a period of time, in order to quickly reduce the temperature inside the distribution cabinet 1, the sealing cover 306 is manually opened. At this time, the coolant 302 absorbs the high-temperature gas inside the distribution cabinet 1. The purpose of setting the moisture-absorbing component 304 in the vent 303 is twofold: first, to prevent foreign objects inside the distribution cabinet 1 from entering the liquid storage tank 3; and second, to prevent water vapor from the coolant 302 evaporating when heated from entering the distribution cabinet 1, thus avoiding the occurrence of dangerous accidents.
