Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and more specifically, to a heat dissipation device for electrical cabinets. Background Technology

[0002] Electrical cabinets are industrial equipment that ensure the stable operation of internal components through physical protection and environmental control systems. Their core functions include rust and corrosion protection, shock absorption and buffering, waterproofing and dustproofing, and temperature control. The electrical components inside the electrical cabinet will generate heat during use, which needs to be dissipated.

[0003] In existing technologies, when electrical cabinets dissipate heat, they generally use cooling fans to extract hot air from the cabinet, thereby cooling the interior. Some also use heat pipes, heat exchangers, etc. to dissipate heat from electrical components, but none of these methods can quickly expel the hot air from the cabinet, resulting in slow heat dissipation. Utility Model Content

[0004] The purpose of this invention is to solve the problem that general heat dissipation devices are inconvenient to quickly extract hot air from electrical cabinets, and to design a heat dissipation device for electrical cabinets.

[0005] To achieve the above objectives, the technical solution of this utility model is a heat dissipation device for an electrical cabinet, comprising an electrical cabinet body, wherein multiple partitions are installed inside the electrical cabinet body, the partitions dividing the electrical cabinet body into multiple holding spaces, two air storage boxes are installed at the upper end of the electrical cabinet body, a lifting piston is installed inside the air storage box, a lifting frame is installed at the upper end of the electrical cabinet body, the lifting frame can drive the lifting piston to move up and down, and an air guide pipe is installed on the air storage box, the air guide pipe can exchange the hot air in the multiple holding spaces.

[0006] Furthermore, the gas storage tank is mounted on the upper part of the electrical cabinet body via a support rod. The gas storage tank has ventilation ports, with one port located at the upper end and the other at the lower end. The air guide pipe includes an outlet pipe, one end of which is connected to the ventilation port. A distribution pipe is installed at the lower end of the outlet pipe, and multiple ventilation valves are installed at the lower end of the distribution pipe. Ventilation pipes are installed at the lower ends of the ventilation valves, and the lower ends of the multiple ventilation pipes extend into different storage spaces. The ventilation pipes of the two gas storage tanks, located at the same position at their lower ends, extend into the same storage space. An actuator is installed on the electrical cabinet body, which can open and close the ventilation valves located at the same position. The two gas storage tanks are connected by a connecting pipe, which connects the space on the side of the gas storage tank where the lifting piston does not have a ventilation port.

[0007] Furthermore, the lifting frame includes a support plate located at the upper end of the electrical cabinet body. The two ends of the support plate are fixedly connected to the air storage tank. A first electric telescopic rod is installed at the upper end of the support plate. A lifting plate is installed at the upper end of the first electric telescopic rod. Connecting rods are installed on both sides at the lower end of the lifting plate. An inlet and outlet are opened at the upper end of the air storage tank. The lower end of the connecting rod passes through the inlet and outlet and is connected to the lifting piston. A sealing ring is installed at the inlet and outlet.

[0008] Furthermore, the ventilation valve is a push-button valve, and a pulley is installed at the button of the push-button valve. The starter includes a second electric telescopic rod installed on the upper end of the electrical cabinet body. A moving rod is installed at the telescopic end of the second electric telescopic rod, and trapezoidal platforms are installed at both ends of the moving rod. A temperature sensor is installed at the lower end of the ventilation pipe.

[0009] Furthermore, a spiral coil is installed inside the outlet pipe, and a cooler is connected to the outside of the spiral coil.

[0010] The beneficial effects of this utility model are as follows: By storing room temperature air in the air storage box, when the temperature inside the electrical cabinet is high, the lifting frame drives the lifting piston to move up and down, thereby allowing the room temperature air in the air storage box to enter the storage space inside the electrical cabinet, and also allowing the high temperature air inside the electrical cabinet to quickly enter the air storage box, thereby quickly cooling the inside of the electrical cabinet and improving heat dissipation efficiency. One air tank has its air vent at the top, and the other air tank has its air vent at the bottom. This allows one air tank to introduce room temperature air into the electrical cabinet, while the other air tank draws away hot air, thus improving heat dissipation efficiency. Temperature sensors can be used to detect the temperature of the storage space inside the electrical cabinet. By opening the corresponding ventilation valves, heat can be dissipated from the designated storage space, thus improving the accuracy of heat dissipation. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] This utility model provides, for example Figure 1-4 The heat dissipation device for an electrical cabinet shown includes an electrical cabinet body 1, with multiple partitions 2 installed inside the electrical cabinet body 1, dividing the electrical cabinet body 1 into multiple holding spaces 3. Two air storage boxes 4 are installed at the upper end of the electrical cabinet body 1, with lifting pistons 5 installed inside the air storage boxes 4. A lifting frame 6 is installed at the upper end of the electrical cabinet body 1, which can drive the lifting pistons 5 to move up and down. An air guide pipe 7 is installed on the air storage boxes 4, which can exchange the hot air in the multiple holding spaces 3.

[0015] The process of heat dissipation for the electrical cabinet by this device is as follows: Under normal conditions, the cooling fan on the electrical cabinet body 1 dissipates heat from the electrical cabinet body 1. When the temperature inside the electrical cabinet body 1 is too high, the lifting frame 6 drives the lifting piston 5 in the air storage box 4 to move up and down. Then, the normal temperature air in the holding space 3 and the hot air in the air storage box 4 can be exchanged through the air pipe 7, which can reduce the temperature inside the electrical cabinet body 1.

[0016] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4 The gas storage box 4 is installed on the upper part of the electrical cabinet body 1 via a support rod 8. The gas storage box 4 has a ventilation port 9. The ventilation port 9 on one gas storage box 4 is located at the upper end, and the ventilation port 9 on the other gas storage box 4 is located at the lower end. The air guide pipe 7 includes an air outlet pipe 10. One end of the air outlet pipe 10 is connected to the ventilation port 9. A distribution pipe 11 is installed at the lower end of the air outlet pipe 10. Multiple ventilation valves 12 are installed at the lower end of the distribution pipe 11. Ventilation pipes 13 are installed at the lower end of the ventilation valves 12. The lower ends of the multiple ventilation pipes 13 extend into different holding spaces 3. The ventilation pipes 13 of the two gas storage boxes 4, which are located at the same position at the lower end, extend into the same holding space 3. An starter 14 is installed on the electrical cabinet body 1. The starter 14 can open and close the ventilation valves 12 located at the same position. The two gas storage boxes 4 are connected by a connecting pipe 27. The connecting pipe 27 connects the space on the side of the gas storage box 4 where the lifting piston 5 does not have a ventilation port 9.

[0017] The process of air exchange between the air storage tank 4 and the holding space 3 via the air duct 7 is as follows: The air exchange valve 12 at the corresponding position is opened by the starter 14. When the lifting frame 6 moves the lifting piston 5 downwards, the ambient temperature air below the lifting piston 5 in the lower air storage tank 4 can enter the holding space 3 through the air exchange port 9, air outlet pipe 10, air distribution pipe 11, air exchange valve 12, and air exchange pipe 13. This allows the high-temperature air in the corresponding holding space 3 to be drawn above the lifting piston 5 from the upper air storage tank 4 via the air exchange port 9, air outlet pipe 10, air distribution pipe 11, air exchange valve 12, and air exchange pipe 13, thereby ventilating the holding space. The storage space 3 is used for heat dissipation. The air in the two air storage boxes 4 located on the other side of the lifting piston 5 flows through the connecting pipe 27. When the lifting frame 6 drives the lifting piston 5 to move upward, the normal temperature air above the lifting piston 5 in the upper air storage box 4 can enter the storage space 3 through the air exchange port 9, the air outlet pipe 10, the air distribution pipe 11, the air exchange valve 12, and the air exchange pipe 13. The air storage box 4 at the lower end of the storage space 4 can draw the high temperature air in the corresponding storage space 3 to the area below the lifting piston 5 through the air exchange port 9, the air outlet pipe 10, the air distribution pipe 11, the air exchange valve 12, and the air exchange pipe 13, so as to exchange heat in the storage space 3.

[0018] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4 The lifting frame 6 includes a support plate 15 located at the upper end of the electrical cabinet body 1. Both ends of the support plate 15 are fixedly connected to the air storage box 4. A first electric telescopic rod 16 is installed at the upper end of the support plate 15. A lifting plate 17 is installed at the upper end of the first electric telescopic rod 16. Connecting rods 18 are installed on both sides of the lower end of the lifting plate 17. An inlet and outlet 19 are opened at the upper end of the air storage box 4. The lower end of the connecting rod 18 passes through the inlet and outlet 19 and is connected to the lifting piston 5. A sealing ring 20 is installed at the inlet and outlet 19.

[0019] The process of the lifting frame 6 driving the lifting piston 5 to move up and down is as follows: the first electric telescopic rod 16 is activated to extend or shorten, which in turn drives the lifting piston 5 to move up and down through the lifting plate 17 and the connecting rod 18. The sealing ring 20 can prevent air leakage.

[0020] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 4 The ventilation valve 12 is a push-button valve, with a pulley 21 installed at the button. The starter 14 includes a second electric telescopic rod 22 installed on the upper part of the electrical cabinet body 1. A moving rod 23 is installed at the telescopic end of the second electric telescopic rod 22, and trapezoidal platforms 24 are installed at both ends of the moving rod 23. A temperature sensor 25 is installed at the lower end of the ventilation pipe 13. The temperature sensor 25 detects the temperature in the holding space 3. When the temperature is too high, the second electric telescopic rod 22 is activated to extend or retract, which in turn drives the moving rod 23 and the trapezoidal platform 24 to move. When the trapezoidal platform 24 moves to the side of the pulley 21, the pulley 21 and the push-button valve can be pushed to one side by the inclined surface of the trapezoidal platform 24, which can open the ventilation valve 12. When the trapezoidal platform 24 leaves the side of the pulley 21, the ventilation valve 12 can be automatically closed.

[0021] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A spiral coil 26 is installed inside the outlet pipe 10. A cooler is connected to the outside of the spiral coil 26. The air passing through the outlet pipe 10 can be cooled through the spiral coil 26, which can quickly cool down the high temperature air and also allow the air in the air storage box 4 to be continuously ventilated, thereby improving the heat dissipation efficiency.
