Description

Technical Field

[0001] This utility model relates to the field of power divider technology, and in particular to a power divider heat dissipation structure. Background Technology

[0002] A power divider is a passive radio frequency device that distributes the energy of one input signal evenly or according to a set ratio to two or more output ports. It is also called a power splitter. It is a key component in radio frequency systems such as communications, radar, and electronic warfare, and its function is to distribute or combine signals.

[0003] In existing power dividers, a direct fan blowing air is used for heat dissipation. When the outside temperature is too high, the air blown by the fan is also hot, which greatly reduces the heat exchange efficiency and may lead to poor heat dissipation. The internal air circulation is not fast enough, which leads to heat accumulation and may affect the stability of the power divider. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a heat dissipation structure for a power divider.

[0005] This utility model is achieved by the following technical solution: a power divider heat dissipation structure, including a protective frame, a power divider fixedly connected to the bottom of the inner wall of the protective frame, a condenser fixedly connected to the outer wall of the protective frame, a heat dissipation component provided inside the protective frame, and a dust removal mechanism provided inside the protective frame.

[0006] The heat dissipation assembly includes a protective frame, a motor is fixedly connected to the inner wall of the protective frame, a rotating rod is fixedly connected to the output end of the motor, a fan blade is fixedly connected to the outer wall of the rotating rod, a flow divider is fixedly connected to the top of the protective frame, a flow hole is opened inside the flow divider, and a cooling pipe is fixedly connected to the inner wall of the flow divider.

[0007] As a further improvement to the above solution, the protective frame is fixedly connected to the outer wall of the protective frame, and the rotating rod is rotatably connected to the inside of the protective frame.

[0008] Through the above technical solution, the motor drives the rotating rod to rotate the fan blades, and at the same time, the condenser operates to generate cold air from the cooling pipes. At this time, the air enters the protective frame through the flow hole at one end of the cooling pipe, thereby dissipating heat from the power divider. Meanwhile, because the distribution frame adopts a flow-dividing design, the fan blades continuously input cold air into the protective frame, and the rotation of the fan blades causes heat to flow out from the distribution frame, thereby realizing the circulation of cold air inside the protective frame, improving the exchange efficiency inside the protective frame, and thus improving the heat dissipation efficiency. At the same time, because the fan blades keep the internal air flowing, heat accumulation is reduced, and the stability of the power divider is improved.

[0009] As a further improvement to the above solution, the dust removal mechanism includes a heat-conducting plate, which is fixedly connected to the top of the power divider, and heat dissipation fins are fixedly connected to the top of the heat-conducting plate.

[0010] As a further improvement to the above solution, a sliding groove is provided on the inner wall of the protective frame, and a sliding plate is slidably connected to the outer wall of the sliding groove.

[0011] As a further improvement to the above solution, a brush plate is fixedly connected to the bottom of the sliding plate, and a motor is fixedly connected to the top of the sliding plate.

[0012] As a further improvement to the above solution, a plurality of brush plates are provided, and the plurality of brush plates are evenly arranged on the surface of the sliding plate.

[0013] As a further improvement to the above solution, a fixing rod is fixedly connected to the output end of the motor, a gear is fixedly connected to the outer wall of the fixing rod, the gear meshes with a toothed plate, and the toothed plate is fixedly connected to the outer wall of the slide groove.

[0014] Through the above technical solution, the motor drives the gear to rotate through the fixed rod. At the same time, the motor is fixed to the sliding plate. When the gear meshes with the toothed plate, the sliding plate drives the brush plate to slide along the outside of the slide groove. The brush plate contacts the surface of the heat dissipation fins, thereby cleaning the dust accumulated on the surface of the heat dissipation fins, improving the heat dissipation efficiency of the heat dissipation fins, preventing dust accumulation from affecting heat dissipation, and improving the service life of the heat dissipation fins.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses a motor-driven rotating rod to rotate the fan blades. Simultaneously, the condenser operates, causing the cooling pipes to generate cold air. This air enters the protective frame through a flow hole at one end of the cooling pipe, thus dissipating heat from the power divider. Furthermore, due to the splitting design of the distribution frame, the fan blades continuously input cold air into the protective frame, while the rotation of the fan blades causes heat to flow out from the distribution frame, achieving cold air circulation within the protective frame. This improves the exchange efficiency within the protective frame, thereby enhancing heat dissipation efficiency. Additionally, the continuous airflow caused by the fan blades reduces heat accumulation and improves the stability of the power divider.

[0017] This invention uses a motor to drive a gear through a fixed rod to rotate. The motor is fixed to a sliding plate. When the gear meshes with the gear plate, the sliding plate drives a brush plate to slide along the outside of the groove. The brush plate contacts the surface of the heat sink fins, thereby cleaning the dust accumulated on the surface of the heat sink fins, improving the heat dissipation efficiency of the heat sink fins, preventing dust accumulation from affecting heat dissipation, and extending the service life of the heat sink fins.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-5 This embodiment provides a power divider heat dissipation structure, including a protective frame 1, a power divider 2 fixedly connected to the bottom of the inner wall of the protective frame 1, a condenser 3 fixedly connected to the outer wall of the protective frame 1, a heat dissipation component 4 inside the protective frame 1, and a dust removal mechanism 5 inside the protective frame 1.

[0028] The heat dissipation assembly 4 includes a protective frame 401, a motor 402 fixedly connected to the inner wall of the protective frame 401, a rotating rod 403 fixedly connected to the output end of the motor 402, a fan blade 404 fixedly connected to the outer wall of the rotating rod 403, a flow divider 405 fixedly connected to the top of the protective frame 1, a flow hole 406 opened inside the flow divider 405, and a cooling pipe 407 fixedly connected to the inner wall of the flow divider 405.

[0029] The protective frame 401 is fixedly connected to the outer wall of the protective frame 1, and the rotating rod 403 is rotatably connected to the inside of the protective frame 1.

[0030] The dust removal mechanism 5 includes a heat-conducting plate 501, which is fixedly connected to the top of the power divider 2, and heat dissipation fins 502 are fixedly connected to the top of the heat-conducting plate 501.

[0031] The inner wall of the protective frame 1 is provided with a sliding groove 503, and a sliding plate 504 is slidably connected to the outer wall of the sliding groove 503.

[0032] A brush plate 505 is fixedly connected to the bottom of the sliding plate 504, and a motor 506 is fixedly connected to the top of the sliding plate 504.

[0033] Several brush plates 505 are provided, and the brush plates 505 are evenly arranged on the surface of the sliding plate 504.

[0034] A fixing rod 507 is fixedly connected to the output end of the motor 506. A gear 508 is fixedly connected to the outer wall of the fixing rod 507. A toothed plate 509 is meshed with the gear 508. The toothed plate 509 is fixedly connected to the outer wall of the slide groove 503.

[0035] The implementation principle of a leakage current protection device for power supervision sites in this application embodiment is as follows: Motor 402 drives rotating rod 403 to rotate fan blade 404. Simultaneously, condenser 3 operates, causing cooling pipe 407 to generate cold air. At this time, the air enters the protection frame 1 through the flow hole 406 at one end of cooling pipe 407, thereby dissipating heat from the power divider 2. Simultaneously, due to the diversion frame 405's diversion design, the fan blade 404 continuously inputs cold air into the protection frame 1, and the rotation of the fan blade 404 causes heat to flow out from the diversion frame 405, thus achieving cold air circulation within the protection frame 1. This improves the exchange efficiency within the protection frame 1, thereby increasing heat dissipation efficiency. Furthermore, the continuous airflow caused by the fan blade 404 reduces heat accumulation and improves overall cooling efficiency. To improve the stability of the power divider 2, a heat-conducting plate 501 is fixed on top of the power divider 2. The heat-conducting plate 501 absorbs the heat of the power divider 2 to the heat dissipation fins 502, thereby improving the heat dissipation efficiency. After long-term use, the motor 506 drives the gear 508 to rotate through the fixing rod 507. At the same time, the motor 506 is fixed to the sliding plate 504. When the gear 508 meshes with the toothed plate 509, the sliding plate 504 drives the brush plate 505 to slide along the outside of the slide groove 503. The brush plate 505 contacts the surface of the heat dissipation fins 502, thereby cleaning the dust accumulated on the surface of the heat dissipation fins 502, improving the heat dissipation efficiency of the heat dissipation fins 502, preventing dust accumulation from affecting heat dissipation, and extending the service life of the heat dissipation fins 502.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
