Description

Technical Field

[0001] This utility model belongs to the technical field of heat dissipation devices, and in particular relates to heat dissipation devices for electrical equipment. Background Technology

[0002] When electrical equipment is running, its internal components continuously generate heat due to energy loss. If this heat cannot be dissipated in time, it can lead to a decline in equipment performance, a shortened lifespan, and even safety faults such as insulation damage and short circuits. Therefore, heat dissipation has become a core requirement for its stable operation. As a centralized installation carrier for electrical components, the distribution box has dense internal components and a closed space, making it easy for heat to accumulate. The risk of overheating is much higher than that of individual devices, making it a critical scenario for heat dissipation protection. To solve the heat dissipation problem of distribution boxes, cooling fans have become the mainstream solution due to their advantages of low cost and high efficiency. By forcing air convection, they can quickly remove heat from the box, maintain a suitable operating temperature, and ensure the safe and stable operation of the distribution box and its internal electrical equipment.

[0003] However, existing heat dissipation devices are not convenient for adjusting the airflow direction during use, making it difficult to adapt to different heat-generating areas inside the distribution box. This can easily lead to insufficient heat dissipation in the heat-generating areas, thus affecting the normal use of the distribution box. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation device for electrical equipment. By setting an adjustment part, it solves the problem that existing heat dissipation devices are not convenient to adjust the airflow direction during use, making it difficult to change according to different heat-generating areas in the distribution box, which easily leads to insufficient heat dissipation in the heat-generating areas, thus affecting the normal use of the distribution box.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a heat dissipation device for electrical equipment, comprising a housing and a fan fixedly connected to the inner wall of the housing, and further comprising: an adjustment part installed inside the housing; a replacement part located above the fan; the adjustment part including a connecting assembly disposed inside the housing; and a power assembly located inside the housing; the connecting assembly including a plurality of brackets fixedly connected to the inner wall of the housing, a connecting block fixedly connected to one side of the plurality of brackets approaching each other, a plurality of rotating shafts rotatably connected to the inner wall of the connecting block, the side of the plurality of rotating shafts away from the connecting block extending into the housing, the outer wall of the rotating shaft rotatably connected to the housing, and a baffle fixedly connected to the outer wall of the rotating shaft, the plurality of connecting blocks and the plurality of rotating shafts being circumferentially distributed.

By setting the adjustment part 2, the transmission component can be driven by the power component 22 to make the multiple baffles 214 in the connecting component 21 deflect synchronously, thereby changing the direction of the wind and realizing flexible adjustment of the wind direction to adapt to different heat dissipation requirements, thereby ensuring the normal operation of the distribution box.

[0018] The replacement unit 3 includes a protective component 31, which is disposed on the top of the housing 101; and a fixing component 32, of which several fixing components 32 are disposed and installed inside the housing 101, arranged in a circumferential pattern. The protective component 31 includes a filter screen 311 disposed on the top of the housing 101, with a protective plate 312 disposed on the top of the filter screen 311. Several positioning elements are disposed inside the filter screen 311, arranged in a circumferential pattern. Each positioning element includes a positioning groove 313 formed in the filter screen 311, which penetrates the filter screen 311. A positioning block 314 is fixedly connected to the top of the housing 101, and the positioning groove 313 is adapted to the positioning block 314. The fixing component 32 includes a fixing connection... The insert block 321 is attached to the bottom of the protective plate 312. The housing 101 has a slot 322. An elastic element is provided in the insert block 321. The slot 322 consists of a strip groove and a triangular groove. The elastic element includes a locking block 323 that is slidably connected to the inner wall of the insert block 321. Two springs 324 are fixedly connected to the inner wall of the insert block 321 near the locking block 323. The two springs 324 are fixedly connected to the locking block 323 on the side near the locking block 323. The locking block 323 is adapted to the slot 322. By setting the replacement part 3, and through the cooperation of the protective component 31 and the fixing component 32, the filter screen 311 can be used to block dust and impurities, and the filter screen 311 can be easily disassembled and replaced, ensuring the filtration effect and ventilation efficiency of the device.

[0019] It should be noted that the control of the fan 102 and the motor 222 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0020] A specific application of this embodiment is as follows: In use, the device can be installed on a distribution box via the housing 101, with one end of the housing 101 having the baffle 214 extending into the distribution box and the other end extending outside. Then, the fan 102 can be started to draw fresh air from the outside into the housing 101 through the filter 311. The filter 311 will block large dust particles and impurities, preventing them from entering the housing 101 with the airflow. The air entering the housing 101 will be driven by the fan 102 and guided by the baffle 214 into the distribution box. When it is necessary to adjust the deflection angle of the baffle 214, the motor 222 can be started, causing its output shaft to drive the face gear 224 to rotate via the second rotating shaft 223. When the face gear 224 rotates, it will drive the first rotating shaft 213 to rotate via the cylindrical gear 225. When the first rotating shaft 213 rotates, the baffle... 214 will also deflect accordingly. When the horizontal tilt angle of the baffle 214 increases, the direction of the wind will gradually move towards the vertical, and vice versa, the direction of the wind will gradually move towards the horizontal, thus completing the adjustment of the wind direction. When the filter 311 needs to be replaced, the protective plate 312 can be pulled to make the insert block 321 slide upward, so that the locking block 323 is squeezed into the insert block 321 under the action of the locking groove 322, thereby compressing the spring 324 and generating elastic force. When the protective plate 312 is pulled up, the insert block 321 will also slide out of the housing 101. At this time, under the action of the elastic force of the spring 324, the locking block 323 will be reset. Then the filter 311 can be removed and a new filter 311 can be installed. At this time, the positioning groove 313 and the positioning block 314 can be used for assistance. Then the protective plate 312 can be reinserted into the housing 101 and the fixing component 32 can be reset.
