Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a heat dissipation mechanism. Background Art

[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switch cabinets, with high-voltage busbars, such as power plants, etc. Some are also equipped with low-frequency load shedding to protect the main equipment.

[0003] In Chinese patent CN107834402B, the present invention discloses a heat dissipation switch cabinet, including an outer shell, which is arranged at the front and rear positions of the heat dissipation switch cabinet, including a front panel and a rear panel, and the front panel and the rear panel are arranged parallel to each other; heat dissipation components are respectively arranged at the two sides of the heat dissipation switch cabinet, and the heat dissipation components on both sides have the same structure and are symmetrical to each other; a base member is arranged at the lower end of the outer shell and fixedly connected thereto; and a wind control component is arranged at the top of the heat dissipation switch cabinet, including an air volume control component, an air inlet pipe and a magnetic ring. The present invention uses the linkage relationship between the various components so that the movement of the driving member can be transmitted to the cover member, and the opening and closing of the cover member is indirectly controlled, so it has a selective ventilation and heat dissipation effect. At the same time, the air volume control function of the wind control component can adjust the overall heat dissipation intensity at any time, so the mutual use of the two makes the heat dissipation more flexible.

[0004] The existing switch cabinets cannot prevent dust from entering the equipment when dissipating heat. When the switch cabinet is working, the internal electrical components will generate heat, so the switch cabinet needs to be cooled. The cooling method usually uses fans. While the fans provide heat dissipation, they also bring dust in the air into the switch cabinet. If dust accumulates on the fans, the heat dissipation effect may deteriorate. If dust accumulates on the insulating materials, the insulation performance may decrease, and even threaten personal safety. In severe cases, dust can easily cause fires, causing immeasurable losses. At the same time, due to the complex circuits and many electrical components in the switch cabinet, staff are required to install and repair the interior. The existing devices are slightly insufficient in safety protection. If non-staff open the switch cabinet, internal components may be damaged.

[0005] Therefore, a heat dissipation mechanism is proposed to address the above problem. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, the utility model solves the problem that the inside of the equipment cannot be dust-proofed during heat dissipation. Since the electrical components inside the switch cabinet will generate heat when the switch cabinet is working, it is necessary to dissipate heat inside the switch cabinet. The heat dissipation method usually adopts fan heat dissipation. While the fan provides heat dissipation, it will also bring dust in the air into the switch cabinet. If dust accumulates on the fan, it may cause the heat dissipation effect to deteriorate. If dust accumulates on the insulating material, it will cause the insulation performance to decline and even threaten personal safety. In severe cases, dust can easily cause fires and cause immeasurable losses. At the same time, due to the complex circuits and many electrical components in the switch cabinet, staff are required to install and repair it. The existing device is slightly insufficient in safety protection. If non-staff open the switch cabinet, it may cause damage to the internal components.

[0023] Embodiment 1

[0024] See also Figure 1 and Figure 2 As shown, a heat dissipation mechanism includes a heat dissipation dustproof component 1, and a heat dissipation heat-conducting component 2 is installed at the bottom of the heat dissipation dustproof component 1; the heat dissipation dustproof component 1 includes a dustproof net 101, a rotating shaft 102, a connecting block 103, a clamping rod 104, a fixing seat 105, a rotating shaft 106, and a limiting block 107. The heat dissipation dustproof component 1 can prevent a large amount of dust from adhering to the heat dissipation fan 201 and the electrical components, thereby affecting the heat dissipation effect. The dustproof net 101 is detachable through the clamping rod 104 and the limiting block 107, and the limiting block 107 is rotating through the rotating shaft 106 and the fixing seat 105. The clamping rod 104 is connected to the connecting block 10 3. The rotating shaft 102 and the dustproof net 101 form a rotating structure; when the cooling fan 201 is working, it will drive air circulation, thereby generating dust. By providing the dustproof net 101, the dustproof net 101 can reduce the dust from entering the switch cabinet body 3, thereby reducing the dust from adhering to the cooling fan 201 and electrical components, and avoiding a large amount of dust from adhering to the cooling fan 201 and electrical components, thereby affecting the heat dissipation effect. At the same time, the dustproof net 101 can be disassembled for cleaning or replacement by rotating the limiting block 107 to be parallel to the fixing seat 105, and then rotating the locking rod 104 to detach from the bottom of the fixing seat 105.

[0025] See also Figure 1 and Figure 3As shown, a heat dissipation mechanism, a heat dissipation and heat-conducting component 2, includes a heat dissipation fan 201, a temperature sensor 202, a relay 203, a mounting plate 204, a flow slot 205, a heat pipe 206, and a heat conducting plate 207. The heat dissipation and heat conducting component 2 can achieve good heat dissipation effect on electrical components that need heat dissipation. The materials of the heat pipe 206 and the heat conducting plate 207 are both set to aluminum-copper alloy, and the shape of the heat pipe 206 is set to "S" shape; by attaching the heat conducting plate 207 to the side of the electrical component that needs heat dissipation, the heat generated by the electrical component will be transferred to the heat conducting plate 207 and the heat conducting pipe 206. At this time, the temperature sensor 202 on the side of the heat dissipation fan 201 senses that the temperature exceeds the set value. At this time, the relay 203 circuit is connected, and the heat dissipation fan 201 starts to work, thereby achieving a heat dissipation effect on the electrical components that need heat dissipation.

[0026] See also Figure 1 , Figure 4 and Figure 5 As shown, a switch cabinet includes a switch cabinet body 3, and a protection control component 4 is installed on the side of the switch cabinet body 3; the protection control component 4 includes a motor 401, a gear 402, a control rod 403, a protection door 404, a support seat 405, an identity information identifier 406, and a protection plate 407. When the switch cabinet body 3 is inspected and repaired, identity identification is required to prevent non-staff from opening the protection door 404. The protection door 404 forms a sliding structure with the switch cabinet body 3 through the control rod 403, and the control rod 403 and the gear 402 are meshed with each other. The protection plate 407 and The support seat 405 constitutes a sliding structure, and the longitudinal cross-sectional area of ​​the protective plate 407 is larger than the longitudinal cross-sectional area of ​​the identity information identifier 406; when the staff needs to inspect the switch cabinet body 3, the identity identification card can be attached to the identity information identifier 406. At this time, when the identity identified by the identity information identifier 406 passes, the switch of the motor 401 will be turned on, and the gear 402 will rotate at this time, thereby opening the protective door 404 to prevent non-staff from opening the protective door 404 and to prevent non-staff from improper operation, thereby causing damage to internal electrical components and the like.

[0027] Working principle: First, place the cleaned and dried dustproof net 101 on the top of the switch cabinet body 3, then rotate the rotating shaft 102, so that the connecting block 103 rotates on the side of the dustproof net 101 through the rotating shaft 102, and the locking rod 104 rotates in the connecting block 103, and rotates until it is locked and fixed at the bottom of the fixing seat 105. At this time, the limiting block 107 rotates on the side of the fixing seat 105 through the rotating shaft 106, and the limiting block 107 is rotated to the vertical direction, so that the limiting block 107 can limit the locking rod 104 to prevent the locking rod 104 from falling off. At this time, the dustproof net 101 will prevent dust and insects from entering the inside of the switch cabinet body 3, and dust will accumulate on the insulating material. The dust on the material will cause the insulation performance to decline and even threaten personal safety. In severe cases, dust can easily cause fires and cause immeasurable losses. Then, when the equipment is running, since the temperature sensor 202 is provided, the temperature sensor 202 refers to a sensor that can sense temperature and convert it into a usable output signal. When the heat conducting plate 207 transmits the temperature to the heat conducting pipe 206, when the temperature exceeds the temperature set by the temperature sensor 202, the relay 203 will start to work, the cooling fan 201 circuit is connected, and the cooling fan 201 will start to dissipate heat, and at the same time, the heat conducting pipe 206 and the heat conducting plate 207 are cooled, so that the electrical components on the side of the heat conducting plate 207 can be cooled;

[0028] Finally, when the staff needs to inspect the switch cabinet body 3, at this time, the protection plate 407 can be pulled to expose the identity information identifier 406 under the protection plate 407, and the identity card can be placed on the identity information identifier 406. At this time, the terminal behind the identity information identifier 406 receives the signal, and after confirming that the information is correct, the motor 401 circuit is turned on. At this time, the motor 401 will drive the gear 402 to rotate. Since the gear 402 and the control rod 403 are engaged with each other, when the gear 402 rotates, the control rod 403 will slide, and the protection door 404 will be opened, so as to prevent non-staff from accidentally opening the protection door 404, thereby increasing the practicality of the device.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
