Technical Field
[0001] This utility model relates to the field of heat dissipation technology for high and low voltage complete sets of equipment, specifically a heat dissipation device for high and low voltage complete sets of equipment. Background Technology
[0002] High and low voltage complete sets of equipment refer to complete sets of electrical equipment used in power systems. According to different voltage levels, they can be divided into high voltage complete sets of equipment and low voltage complete sets of equipment. They usually include equipment such as transformers, distribution cabinets, and control cabinets. In the process of heat dissipation of distribution cabinets, heat dissipation devices are required.
[0003] A Chinese patent with authorization announcement number CN 220692668 U discloses a heat dissipation device for high and low voltage switchgear, relating to the technical field of high and low voltage switchgear. It addresses the problem that existing heat dissipation devices for high and low voltage switchgear tend to blow dust into the equipment during use, potentially causing damage. The device includes a main body, auxiliary structure, motor, adjustment structure, flipping structure, and limiting structure. The main body is a housing for the high and low voltage switchgear, with an internal cavity. The auxiliary structure is located inside the main body; the motor is located inside the auxiliary structure; the adjustment structure is located inside the auxiliary structure; the flipping structure is located inside the auxiliary structure; and the limiting structure is located inside the flipping structure. The motor rotates, driving a fan, which in turn accelerates airflow, thus dissipating heat from the switchgear. A filter prevents dust from entering the equipment and causing damage.
[0004] Existing heat dissipation devices typically use heat dissipation troughs of fixed area to cool the inside of high and low voltage switchgear. However, due to the limited heat dissipation area, the heat dissipation efficiency is low. Therefore, a heat dissipation device for high and low voltage switchgear is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a heat dissipation device for high and low voltage complete sets of equipment.
[0006] The technical solution adopted by this utility model to solve its technical problem is a heat dissipation device for high and low voltage complete sets of equipment, including a cabinet. Electronic components are installed inside the cabinet. A cabinet door is installed on the cabinet, and a control panel is installed on the cabinet door. An mounting plate is installed on the rear panel of the cabinet, and a first heat dissipation groove is formed on the mounting plate. A second heat dissipation groove is formed on the side wall of the cabinet. Two sliding frames are symmetrically installed on the outer wall of the cabinet. A fixed plate is installed on the bottom side of the two sliding frames. Sliding plates are slidably assembled inside the two sliding frames. Multiple baffles are fixedly installed between the two sliding plates. The baffles correspond to the positions of the second heat dissipation grooves. An electric telescopic rod is fixedly installed on the side wall of the cabinet. A push rod is installed on the electric telescopic rod. The push rod is fixedly connected to one of the baffles. The electric telescopic rod is connected to the control panel through an internal circuit. A fan is installed on the side wall of the cabinet. A third fan is installed on the inner wall of the cabinet at the location of the fan. The system includes a third filter assembly containing a third filter screen. A temperature sensor is installed on the outer wall of the cabinet, with its probe mounted on the inner wall. The temperature sensor is connected to the control panel via an internal circuit. A second filter assembly, containing a second filter screen, is installed on the inner wall of the cabinet at the second heat dissipation slot. When the temperature rises and reaches a threshold, the control panel activates an electric telescopic rod, pushing all the baffles vertically downwards. This opens the second heat dissipation slot, and simultaneously, the fan operates, expelling hot air from inside the cabinet. Cold air from outside enters the cabinet through the first and second heat dissipation slots and flows within, rapidly cooling the electronic components inside the cabinet. This achieves highly efficient heat dissipation by increasing the heat dissipation area and accelerating airflow, thus improving overall heat dissipation efficiency.
[0007] Preferably, a first filter assembly is installed on the inner wall of the mounting plate at the first heat dissipation groove. The first filter assembly has the same structure as the second and third filter assemblies. The first filter assembly includes two guide plates, each with a guide groove. A connecting plate is fitted into the guide groove, and a first filter screen is installed between the two connecting plates. Screws are installed on the connecting plates and the guide plates. The mounting plate can be disassembled by unscrewing the screws between the mounting plate and the cabinet. Then, the four screws are turned to unscrew the screws, and the connecting plate is pulled out from the guide groove of the guide plate, thus achieving quick disassembly of the first filter screen. Similarly, the second and third filter screens can be quickly disassembled. This structure allows for quick disassembly of the filter screens, facilitating cleaning and improving the convenience of filter screen disassembly.
[0008] The advantages of this utility model are:
[0009] 1. This utility model utilizes a control panel to activate an electric telescopic rod when the temperature rises and reaches a threshold. The push rod moves all the baffles vertically downwards, opening the second heat dissipation trough. Simultaneously, the fan operates, expelling hot air from inside the cabinet. Cold air from the outside enters the cabinet through the first and second heat dissipation troughs and flows within the cabinet, rapidly cooling the electronic components inside. This achieves highly efficient heat dissipation within the cabinet. This structure increases the heat dissipation area and accelerates airflow, thus improving heat dissipation efficiency.
[0010] 2. This utility model allows for the disassembly of the mounting plate by unscrewing the screws between the mounting plate and the cabinet. Then, by rotating the four screws and unscrewing them, the connecting plate can be pulled out from the guide groove of the guide plate, thus enabling the quick disassembly of the first filter screen. Similarly, the second and third filter screens can be quickly disassembled. This structure allows for the quick disassembly of the filter screens, facilitating cleaning and improving the convenience of filter screen disassembly. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] Please see Figure 1-4As shown, a heat dissipation device for high and low voltage complete sets of equipment includes a cabinet 1, an electronic component 21 installed inside the cabinet 1, a cabinet door 2 installed on the cabinet 1, a control panel 3 installed on the cabinet door 2, an mounting plate 4 installed on the rear panel of the cabinet 1, a first heat dissipation groove 5 opened on the mounting plate 4, a second heat dissipation groove 6 opened on the side wall of the cabinet 1, two sliding frames 7 symmetrically installed on the outer wall of the cabinet 1, a fixing plate 8 installed on the bottom side of the two sliding frames 7, a sliding plate 9 slidably assembled inside the two sliding frames 7, a plurality of baffles 10 fixedly installed between the two sliding plates 9, the baffles 10 corresponding to the positions of the second heat dissipation grooves 6, an electric telescopic rod 11 fixedly installed on the side wall of the cabinet 1, a push rod 12 installed on the electric telescopic rod 11, and the push rod 1... 2 is fixedly connected to one of the baffles 10. The electric telescopic rod 11 is connected to the control panel 3 through an internal circuit. A fan 13 is installed on the side wall of the cabinet 1. A third filter assembly is installed on the inner wall of the cabinet 1 at the location of the fan 13. A third filter screen is installed inside the third filter assembly. A temperature sensor 14 is installed on the outer wall of the cabinet 1. The probe of the temperature sensor 14 is installed on the inner wall of the cabinet 1. The temperature sensor 14 is connected to the control panel 3 through an internal circuit. A second filter assembly is installed on the inner wall of the cabinet 1 at the location of the second heat dissipation slot 6. A second filter screen 15 is installed inside the second filter assembly. During operation, existing heat dissipation devices typically use heat dissipation slots of fixed area when dissipating heat from high and low voltage complete sets of equipment. The equipment's internal cooling system is designed to dissipate heat, but due to limited cooling area, the cooling efficiency is low. During operation, the high and low voltage switchgear generates heat. The first cooling trough 5 continuously cools the interior of cabinet 1, while a temperature sensor 14 (PT100 model) detects the temperature inside cabinet 1. The temperature sensor 14 sends a detection signal to control panel 3. When the temperature rises and reaches a threshold, control panel 3 activates the electric telescopic rod 11. The push rod 12 on the electric telescopic rod 11 pushes the baffle 10 vertically downwards. The baffle 10 causes two sliding plates 9 to move vertically downwards within two sliding frames 7. The two sliding plates 9 then move all the baffles... When plate 10 moves vertically downwards, all baffles 10 no longer block the second heat dissipation slot 6, and the second heat dissipation slot 6 opens. At the same time, control panel 3 controls fan 13 to operate, and fan 13 exhausts the hot air inside cabinet 1. Cold air from the outside enters cabinet 1 through the first heat dissipation slot 5 and the second heat dissipation slot 6 and flows inside cabinet 1, rapidly cooling the electronic components 21 inside cabinet 1, thus achieving efficient heat dissipation inside cabinet 1. The first filter 19, second filter 15, and third filter filter the air entering cabinet 1. This structure achieves efficient heat dissipation inside cabinet 1 by increasing the heat dissipation area and accelerating the airflow speed, which is beneficial to improving heat dissipation efficiency.
[0020] Please see Figure 5As shown, a first filter assembly is installed on the inner wall of the mounting plate 4 at the first heat dissipation groove 5. The first filter assembly has the same structure as the second and third filter assemblies. The first filter assembly includes two guide plates 16, each with a guide groove 17. A connecting plate 18 is fitted into the guide groove 17, and a first filter screen 19 is installed between the two connecting plates 18. Screws 20 are installed on the connecting plates 18 and the guide plates 16. During operation, existing heat dissipation devices typically require filters to block dust during the heat dissipation process of high and low voltage complete sets of equipment. However, after long-term use, the filters need to be disassembled and cleaned. Due to the cumbersome disassembly process, the filter screen is not easy to disassemble. By unscrewing the screws between the mounting plate 4 and the cabinet 1, the mounting plate 4 can be disassembled. Then, the four screws 20 are turned to unscrew the screws 20. After that, the connecting plate 18 can be pulled out from the guide groove 17 of the guide plate 16, thus achieving quick disassembly of the first filter screen 19. Similarly, the second filter screen 15 and the third filter screen can be quickly disassembled. This structure allows for quick disassembly of the filter screens, facilitating cleaning and improving the convenience of filter screen disassembly.
[0021] Working principle: Existing heat dissipation devices typically use fixed-area heat dissipation tanks to cool the inside of high and low voltage switchgear. However, due to the limited heat dissipation area, the heat dissipation efficiency is low. During operation, high and low voltage switchgear generates a certain amount of heat. The first heat dissipation tank 5 continuously dissipates heat from the inside of the cabinet 1, while the temperature sensor 14 (PT100 model) detects the temperature inside the cabinet 1. The temperature sensor 14 sends a detection signal to the control panel 3. When the temperature rises and reaches a threshold, The control panel 3 controls the operation of the electric telescopic rod 11. The push rod 12 on the electric telescopic rod 11 pushes the baffle 10 on it to move vertically downward. The baffle 10 drives the two sliding plates 9 to move vertically downward within the two sliding frames 7. The two sliding plates 9 drive all the baffles 10 to move vertically downward. At this time, all the baffles 10 no longer block the second heat dissipation slot 6, and the second heat dissipation slot 6 opens. At the same time, the control panel 3 controls the operation of the fan 13. The fan 13 exhausts the hot air inside the cabinet 1, and the cold air from the outside enters the cabinet through the first heat dissipation slot 5 and the second heat dissipation slot 6. The airflow within the cabinet 1 rapidly cools the electronic components 21 inside, achieving efficient heat dissipation. The first filter 19, second filter 15, and third filter filter the air entering the cabinet 1. This structure increases the heat dissipation area and accelerates airflow, thus improving heat dissipation efficiency. Existing heat dissipation devices typically require filters to block dust during the cooling process of high and low voltage switchgear, but these filters require cleaning after prolonged use. The disassembly and cleaning process is cumbersome, resulting in poor ease of filter removal. By unscrewing the screws between the mounting plate 4 and the cabinet 1, the mounting plate 4 can be removed. Then, the four screws 20 are turned to unscrew them. After that, the connecting plate 18 is pulled out from the guide groove 17 of the guide plate 16, which allows for quick disassembly of the first filter 19. Similarly, the second filter 15 and the third filter can be quickly disassembled. This structure allows for quick disassembly of the filter, facilitating cleaning and improving the convenience of filter removal.
