Description

Technical Field

[0001] This utility model relates to the field of water-cooled microwave circulator technology, and in particular to a water-cooled microwave circulator. Background Technology

[0002] A water-cooled microwave circulator is a microwave device that innovatively integrates a traditional microwave circulator with a water-cooling system. Its core design concept is to significantly improve the device's heat dissipation efficiency through a forced convection heat transfer mechanism using circulating cooling liquid. While maintaining the original electromagnetic characteristics of the microwave circulator, this device forms a complete thermal management system through built-in liquid cooling channels and external heat dissipation devices, effectively solving the temperature rise problem caused by dielectric loss and conductor loss under high-power operating conditions.

[0003] When existing water-cooled microwave circulators operate at continuous high power, they rely solely on the water-cooling circulation system. However, due to limitations in the heat capacity of the coolant, insufficient flow rate, or bottlenecks in heat exchange efficiency, heat cannot be completely dissipated in a timely manner. This insufficient heat dissipation capacity can lead to problems such as local temperature rise and thermal stress accumulation in the device, which in turn can cause negative effects such as material performance degradation, decreased signal transmission stability, and even shortened equipment lifespan. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a water-cooled microwave circulator. This solves the problem that when the existing water-cooled microwave circulator is running at high power continuously, the limited heat capacity of the coolant in the water-cooling system, insufficient flow rate, or low heat exchange efficiency leads to insufficient heat dissipation, resulting in local overheating and thermal stress accumulation of the device, which in turn causes problems such as deterioration of material performance, unstable signal, and shortened lifespan.

[0005] This utility model also provides a water-cooled microwave circulator as described above, including a housing, a first flange fixedly connected to one side of the housing, a waveguide fixedly connected to the side of the first flange away from the housing, a heat-conducting medium disposed inside the waveguide, both ends of the heat-conducting medium penetrating the waveguide, a second flange disposed outside the heat-conducting medium, and a heat sink fixedly connected to the side of the second flange away from the waveguide. Through the cooperation of the housing, the first flange, the waveguide, the heat-conducting medium, the second flange and the heat sink, the heat of the waveguide is absorbed by the heat-conducting medium and conducted to the heat sink. This can compensate for the heat accumulation problem caused by insufficient heat capacity, flow rate or heat exchange efficiency of the coolant in the water-cooling system, and avoid local overheating, thermal stress and the resulting performance degradation, signal instability or shortened lifespan of the device.

A support block is fixedly connected to the upper end of the mounting plate, and a mounting block is fixedly connected to the upper end of the support block. A limiting groove is formed at the top of the mounting block. A positive and negative lead screw is rotatably connected inside the limiting groove. Two limiting blocks are threaded to the outer side of the positive and negative lead screw. Through the cooperation of the support block, mounting block, limiting groove, positive and negative lead screw and limiting blocks, the positive and negative lead screw converts the rotational motion into linear displacement and drives the limiting blocks to move in both directions. Finally, the sliding cooperation between the limiting blocks and the limiting groove constrains its motion trajectory, forming a complete closed-loop motion control system.

[0010] According to the present invention, a water-cooled microwave circulator is provided, wherein a support plate is fixedly connected to one side of the mounting block, a motor is fixedly connected to the upper end of the support plate, and the output end of the motor is fixedly connected to the positive and negative lead screws. Through the cooperation of the support plate, the motor and the positive and negative lead screws, the rotational power of the motor is efficiently transmitted to the positive and negative lead screws, so that they obtain a precise and controllable bidirectional rotational driving force.

[0011] According to the water-cooled microwave circulator provided by this utility model, a connecting block is fixedly connected to the top of the limiting block, and a cleaning plate is fixedly connected to one end of the connecting block. Through the cooperation of the connecting plate and the cleaning plate, the rigidly connected connecting plate accurately transmits the linear displacement of the limiting block to the cleaning plate, so that the cleaning plate moves synchronously while maintaining parallel contact with the surface of the heat sink. During this process, the specially designed scraping structure on the edge of the cleaning plate continuously generates frictional contact with the surface of the heat sink, thereby efficiently peeling off and removing dust particles attached to the inner and outer surfaces of the heat sink, realizing the physical cleaning function of the heat dissipation channel.

[0012] According to the present invention, a water-cooled microwave circulator is provided, wherein a traction frame is fixedly connected to the top of the mounting plate, a traction tube is rotatably connected to the inner wall of the traction frame, a traction plate is slidably connected to the outer side of the traction tube, and the traction plate is fixedly connected to the cleaning plate.

[0013] The water-cooled microwave circulator in this technical solution absorbs the heat of the waveguide through the heat-conducting medium and conducts it to the heat sink. This can compensate for the heat accumulation problem caused by insufficient heat capacity, flow rate or heat exchange efficiency of the coolant in the water-cooling system, avoid local overheating of the device, thermal stress and the resulting performance degradation, signal instability or shortened life. In addition, the device is smaller than non-standard products, which can reduce the space occupied in the whole equipment and save equipment energy. Attached Figure Description

[0022] Reference Figure 1-4 This utility model discloses a water-cooled microwave circulator, comprising a housing 1, a first flange 2 fixedly connected to one side of the housing 1, a waveguide 3 fixedly connected to the side of the first flange 2 away from the housing 1, a heat-conducting medium 4 disposed inside the waveguide 3, with both ends of the heat-conducting medium 4 penetrating the waveguide 3, a second flange 5 disposed outside the heat-conducting medium 4, a heat sink 6 fixedly connected to the side of the second flange 5 away from the waveguide 3, a mounting plate 13 disposed outside the waveguide 3, a support block 14 fixedly connected to the upper end of the mounting plate 13, a mounting block 15 fixedly connected to the upper end of the support block 14, and a limit groove 16 formed at the top of the mounting block 15.

[0023] Specifically, during assembly, the outer shell 1 and the waveguide 3 are rigidly connected via the first flange 2. The first flange 2 differs in shape from the standard microwave flange; it is rectangular, thus saving materials and reducing energy consumption. During operation, the heat generated by the waveguide 3 is efficiently conducted to the radiator 6 via the heat-conducting medium 4 for forced cooling. This design effectively compensates for the heat dissipation defects of the water-cooling system when the coolant's heat capacity is insufficient, the flow rate is low, or the heat exchange efficiency decreases. This fundamentally eliminates the risks of localized overheating, thermal stress concentration, and the resulting performance degradation, signal distortion, and lifespan reduction. The synchronously started motor 20 drives the forward and reverse lead screws 17 to rotate. Through the axial movement of the limit block 18 within the limit groove 16, it drives the connecting block 21 to push the cleaning plate 22 to perform linear dust scraping. Simultaneously, the traction plate 25 moves synchronously along the traction tube 24 of the traction frame 23. This dual guiding mechanism ensures that the cleaning plate 22 achieves smooth, vibration-free movement, thereby maintaining the cleanliness of the radiator 6 surface to guarantee optimal heat dissipation performance.
