Description

Technical Field

[0001] This utility model relates to the field of active power filter heat dissipation technology, and in particular to an active power filter with rapid heat dissipation. Background Technology

[0002] An active power filter is a new type of power electronic device used to dynamically suppress harmonics and compensate for reactive power.

[0003] Active power filters generate a lot of heat during operation. If the heat is not dissipated, the device temperature will be too high, which will affect the filtering compensation effect of the device and reduce the service life of the device. Active power filters are bound to have faults and problems. Traditional devices are connected by bolts, and the disassembly and maintenance process is troublesome and slow, which greatly affects the maintenance efficiency and is very inconvenient.

[0004] An existing patent (publication number: CN213402456U) discloses an active power filter for easy heat dissipation, comprising a main box, a lock, a door, and a motor box. The main box has a connection port at its upper end, a guide rail on its left outer wall, a baffle inside the guide rail, and a short rod at its lower end. The left end of the short rod is rotatably connected to a pull rod via a shaft. The left side of the guide rail is fixedly connected to a semi-circular fastener. A filter plate is located on the left inner wall of the main box, and a fan is located at the right end of the filter plate. The door is rotatably connected to the left wall of the main box via a shaft. A display screen is located at the upper end of the door, and a controller is located at the lower end of the display screen. This utility model effectively dissipates heat and cools the device through the filter plate and fan, while the door and lock greatly simplify maintenance and replacement, improving work efficiency and making it highly practical.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing active power filters typically have fixed heat dissipation devices, making them inconvenient to maintain and replace. Furthermore, they rely solely on mounting brackets to maintain a certain height for passive insect prevention, resulting in poor insect control and making them susceptible to pest infestations in some areas. Existing patents cannot solve these problems, thus hindering user adoption.

[0006] To address this, a fast-heat dissipation active power filter is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide an active power filter with rapid heat dissipation, which aims to solve the problems of existing active power filters. The heat dissipation device is generally fixed during use, which makes it inconvenient to maintain and replace. Furthermore, it only relies on the mounting bracket to maintain a certain height for passive insect prevention, which makes it ineffective in preventing insect damage. This makes it easy for the filter to be damaged by insects in some areas. Existing patents cannot solve this problem, which is not conducive to the use of the filter.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a fast heat dissipation active power filter, comprising a support frame, a cabinet-type active power filter body is provided on the top of the support frame, an auxiliary mechanism is provided at the bottom of the inner side of the cabinet-type active power filter body, the auxiliary mechanism includes a support component and a heat dissipation component, the support component is provided at the bottom of the cabinet-type active power filter body, and the heat dissipation component is provided inside the support component;

[0009] The load-bearing assembly includes two slide rails, a protective housing, a fixing plate, a load-bearing housing, and a protective plate. The two slide rails are bolted to the bottom of both sides of the inner side of the cabinet-type active power filter body. The protective housing is slidably connected to the inner side of the slide rails. The fixing plate is rotatably connected to the bottom of the inner side of the protective housing. The load-bearing housing is bolted to the inner side of the protective housing. The protective plate is snapped onto the top of the protective housing.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1.

At the same time, the support component is provided with a sliding structure inside so that the user can move the support component and the heat dissipation component, thereby facilitating the user to perform maintenance and replacement work.

[0019] 2. This application incorporates a heat dissipation component. When using this fast-heat-dissipating active power filter, the user places the insect repellent inside the heat dissipation component and then activates it to drive airflow inside the cabinet-type active power filter. This allows the heat dissipation component and the supporting component to form an air circulation channel, enabling the insect repellent's odor to be released from the bottom of the cabinet-type active power filter via the circulating air, thus facilitating heat dissipation and insect repellency for the cabinet-type active power filter.

[0026] 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 protection scope of the present utility model.

[0027] Please see Figure 1-5 A fast heat dissipation active power filter includes a support frame 1, a cabinet-type active power filter body 2 is provided on the top of the support frame 1, and an auxiliary mechanism 3 is provided at the bottom inside the cabinet-type active power filter body 2. The auxiliary mechanism 3 includes a support component 301 and a heat dissipation component 302. The support component 301 is provided at the bottom of the cabinet-type active power filter body 2, and the heat dissipation component 302 is provided inside the support component 301.

[0028] The load-bearing assembly 301 includes two slide rails 301a, a protective housing 301b, a fixing plate 301c, a load-bearing housing 301d, and a protective plate 301e. The two slide rails 301a are bolted to the bottom of the inner sides of the cabinet-type active power filter body 2. The protective housing 301b is slidably connected to the inner side of the slide rails 301a. The fixing plate 301c is rotatably connected to the bottom of the inner side of the protective housing 301b. The load-bearing housing 301d is bolted to the inner side of the protective housing 301b. The protective plate 301e is snapped onto the top of the protective housing 301b.

[0029] In this embodiment: by setting two slide rails 301a, a protective shell 301b, a fixing plate 301c, a supporting shell 301d, and a protective plate 301e, when using this fast-heat dissipating active power filter, the user can combine the slide rails 301a with the cabinet-type active power filter body 2, so that the slide rails 301a, together with the protective shell 301b, can fix the fixing plate 301c, the supporting shell 301d, the protective plate 301e, the central channel 302a, the ventilation pipe 302b, the cooling fan 302c, and the insect repellent 302d to the bottom inside of the cabinet-type active power filter body 2. Furthermore, the user can move the cooling fan 302c by dragging the protective shell 301b inside the slide rails 301a, which facilitates the user's maintenance and replacement work.

[0030] Specifically, such as Figure 2 , Figure 4 As shown, the heat dissipation assembly 302 includes a central channel 302a connected to the top of the protective plate 301e. A ventilation pipe 302b is fixedly connected to the bottom of the central channel 302a. The inner surface of the ventilation pipe 302b is close to the top surface of the fixed plate 301c.

[0031] Specifically, such as Figure 2, Figure 4 As shown, a cooling fan 302c is provided at the bottom of the ventilation duct 302b, and the surface of the cooling fan 302c is bolted to the inside of the supporting housing 301d.

[0032] Specifically, such as Figure 2 , Figure 4 As shown, an insect repellent 302d is provided on the top of the cooling fan 302c, and the outer side of the insect repellent 302d is engaged with the inner side of the central channel 302a.

[0033] In this embodiment: by setting up a centralized channel 302a, a ventilation pipe 302b, a cooling fan 302c, and an insect repellent 302d, while ensuring the normal operation of the cabinet-type active power filter body 2, the user can combine the cooling fan 302c with the supporting housing 301d so that the supporting housing 301d can protect and move the cooling fan 302c. Then, the supporting housing 301d can be bolted to the fixing plate 301c to fix the cooling fan 302c inside the protective housing 301b. At this time, the user can connect the protective plate 301e to the protective housing 301b. The connection is made so that the ventilation pipe 302b at the bottom of the protective plate 301e can contact the top of the cooling fan 302c, thereby forming an airflow channel with the cooling fan 302c, the ventilation pipe 302b, and the central channel 302a at the top of the protective plate 301e. At this time, the cooling fan 302c can drive the air inside the cabinet-type active power filter body 2 to leave, so that the air can carry away the odor of the insect repellent 302d restricted inside the central channel 302a, thereby spreading the odor of the insect repellent 302d to the bottom of the cabinet-type active power filter body 2, thus achieving the dual purpose of heat dissipation and insect repellency.

[0034] Specifically, such as Figure 1 , 5 As shown, an auxiliary component 4 is provided at the bottom of the inner side of the cabinet-type active power filter body 2. The auxiliary component 4 includes a lubrication channel 401 that is inserted into the front side of the top of the slide rail 301a. A soft contact block 402 is snapped into the bottom of the lubrication channel 401. Holes are opened on the surface of the soft contact block 402.

[0035] Specifically, such as Figure 1 , 5 As shown, a control valve 403 is threadedly connected to the inner side of the lubrication channel 401, and a rotating handle is fixedly connected to the front side of the control valve 403.

[0036] In this embodiment: by setting up a lubrication channel 401, a soft contact block 402 and a control valve 403, the lubrication channel 401, the soft contact block 402 and the control valve 403 cooperate with each other, which can help the user maintain the slide rail 301a and the protective shell 301b and avoid the protective shell 301b from being inconvenient to move.

[0037] Specifically, such as Figure 3 As shown, a movable handle is fixedly connected to the front side of the protective housing 301b, and a ventilation opening is provided at the bottom of the protective housing 301b.

[0038] Specifically, such as Figure 3 As shown, the inner side of the fixing plate 301c is in contact with the surface of the supporting housing 301d, and the surface of the protective plate 301e has holes.

[0039] In this embodiment: by setting up a protective shell 301b, a fixing plate 301c and a protective plate 301e, the protective shell 301b, the fixing plate 301c and the protective plate 301e cooperate with each other to protect the heat dissipation component 302, and at the same time can cooperate with the heat dissipation component 302 to form an air flow channel for quickly expelling hot air inside the cabinet-type active power filter body 2.

[0040] Working Principle: First, when using the cabinet-type active power filter body 2, the user can combine the slide rail 301a with the cabinet-type active power filter body 2. The slide rail 301a, in conjunction with the protective housing 301b, can fix the fixing plate 301c, the supporting housing 301d, the protective plate 301e, the central channel 302a, the ventilation pipe 302b, the cooling fan 302c, and the insect repellent 302d to the bottom inner side of the cabinet-type active power filter body 2. Furthermore, by dragging the protective housing 301b inside the slide rail 301a, the user can move the cooling fan 302c, facilitating maintenance and replacement. When ensuring the normal operation of the cabinet-type active power filter body 2, the user can combine the cooling fan 302c with the supporting housing 301d, so that the supporting housing 301d can protect and move the filter. The cooling fan 302c is activated, and then the supporting housing 301d and the fixing plate 301c can be bolted together to fix the cooling fan 302c inside the protective housing 301b. At this time, the user can snap the protective plate 301e into the protective housing 301b so that the ventilation pipe 302b at the bottom of the protective plate 301e abuts against the top of the cooling fan 302c, thereby forming an airflow channel with the cooling fan 302c, the ventilation pipe 302b, and the central channel 302a at the top of the protective plate 301e. At this time, the cooling fan 302c can drive the air inside the cabinet-type active power filter body 2 to leave, so that the air can drive the odor of the insect repellent 302d restricted inside the central channel 302a to leave, thereby spreading the odor of the insect repellent 302d to the bottom of the cabinet-type active power filter body 2, thus achieving the dual purpose of heat dissipation and insect repellency.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the present utility model should be included within the protection scope of the present utility model.
