DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: Microwave frequency-based synthesizer, such as Figs. 1-4 As shown, it includes a synthesizer body 1, which is composed of a core circuit assembly 2 and a housing 3. The housing 3 has basic heat dissipation perforated plates 4 on both sides and a mesh aperture adjustment mechanism 5 inside the housing 3.

[0027] The mesh aperture adjustment mechanism 5 includes a transverse drive rod 51 disposed inside the lower cavity 32 of the outer shell 3. The right side of the transverse drive rod 51 extends to the outside of the lower cavity 32 and is connected to the output end of the telescopic cylinder 52 mounted on a side frame of the lower cavity 32. The telescopic cylinder 52 can drive the transverse drive rod 51 to make a transverse translational movement inside the lower cavity 32. The end of the transverse drive rod 51 is provided with a connecting positioning block 511. The extension column extending from the connecting positioning block 511 is connected to one hinge point of the bending linkage block 54 to form a movable hinge connection. At the same time, the other two hinge points of the bending linkage block 54 are respectively connected to the extension column extending from the fixed plate 55 fixedly installed on the top plate of the lower cavity 32, and the extension column extending from the lifting column 56 that penetrates the lower cavity 32 and extends upward into the upper cavity 31. The lifting column 56 is connected to the ventilation adjustment plate 41 with heat dissipation holes.

[0028] When the device is not started or in standby, the ventilation adjusting plate 41 is attached to the base heat dissipation hole plate 4, and the mesh holes of the two are staggered by half. In this description, due to the mesh hole adjustability of the present application, the mesh hole diameter is relatively large. After the synthesizer main body 1 works for a long time, the internal temperature will rise. At this time, the telescopic cylinder 52 is started, and its output end pushes the horizontal drive rod 51. Since the right side of the horizontal drive rod 51 is connected to the output end of the telescopic cylinder 52, and the horizontal drive rod 51 passes through the first guide cylinder 53, under the pushing force of the telescopic cylinder 52, the horizontal drive rod 51 starts to move horizontally in the lower cavity 32. With the movement of the horizontal drive rod 51, the connecting positioning block 511 at the end of the horizontal drive rod 51 moves synchronously. The extension column of the connecting positioning block 511 is movably connected to one of the hinge points of the bent linkage block 54, thereby driving the bent linkage block 54 to rotate around the hinge point. The other two hinge points of the bent linkage block 54 are movably connected to the extension column of the fixed plate 55 and the lifting column 56, respectively. When the bent linkage block 54 rotates, the position of the hinge point connected to the lifting column 56 changes, thereby pushing the lifting column 56 to move upward in the second guide cylinder 57. When the lifting column 56 moves upward, it drives the ventilation adjusting plate 41 on the upper end of the bearing plate 58 to move upward synchronously. Since the ventilation adjusting plate 41 is closely attached to the base heat dissipation hole plate 4, and the heat dissipation holes on the ventilation adjusting plate 41 are consistent with the heat dissipation hole diameter of the base heat dissipation hole plate 4, as the position of the ventilation adjusting plate 41 changes, the overlapping area between the heat dissipation holes of the two changes until the heat dissipation holes overlap, at which time the ventilation hole diameter area is the largest, thereby promoting air circulation and enhancing heat dissipation. When it is necessary to reduce the hole diameter, the horizontal drive rod 51 can be moved in the opposite direction by the contraction piston. In this description, a certain space is reserved at the top of the upper cavity 31 to provide a certain distance adjustment of the ventilation adjusting plate 41 upward.

[0029] As shown in Figs. 1-4 , the communication area of the lower cavity 32 is provided with a first guide cylinder 53, the inner ring of the first guide cylinder 53 is a smooth structure, and the horizontal drive rod 51 passes through the first guide cylinder 53 when moving horizontally. The communication area of the upper cavity 31 and the lower cavity 32 is provided with a second guide cylinder 57, the inside of the second guide cylinder 57 is also a smooth structure, and the lifting column 56 extends to the upper cavity 31 by passing through the second guide cylinder 57.

[0030] Through the cooperation of the first guide cylinder 53 and the second guide cylinder 57, the frictional resistance of the horizontal drive rod 51 and the lifting column 56 when moving can be reduced, and smooth movement can be ensured.

[0031] As shown in Figs. 1-4 , the upper end of the lifting column 56 is provided with a bearing plate 58, the two sides of the bearing plate 58 are provided with positioning plates, and the ventilation adjusting plate 41 is detachably installed on the bearing plate 58 through the positioning plates on both sides. The ventilation adjusting plate 41 can be conveniently detached from the bearing plate 58 for overall cleaning, inspection or replacement.

[0032] Embodiment two: Microwave frequency-based synthesizer, such as Figs. 1-4 As shown in the figure, a partition plate 6 is arranged between the upper cavity 31 and the lower cavity 32, and a plurality of groups of heat sinks 61 are arranged on the partition plate 6 in an array form.

[0033] A temperature sensor 7 is arranged on the top of the upper cavity 31, and the temperature sensor 7 is electrically connected to a PLC controller 71, and the PLC controller 71 is also electrically connected to the telescopic air cylinder 52 and the heat sink 61.

[0034] In use, when the synthesizer body 1 is started, the core circuit assembly 2 starts to work, the temperature sensor 7 on the top of the upper cavity 31 monitors the internal temperature in real time, and the temperature sensor 7 transmits the temperature data to the PLC controller 71 in real time. If the temperature sensor 7 detects that the temperature exceeds the preset normal working range, the PLC controller 71 first starts the telescopic air cylinder 52 to change the mesh aperture of the base heat dissipation hole plate 4 and the ventilation adjusting plate 41, so that the mesh aperture becomes larger, and then the heat sink 61 is started to cool the inside. When the temperature is lower than the preset normal working range, the mesh aperture can be changed to be smaller. The heat sink 61, the temperature sensor 7 and the PLC controller 71 in the application are all mature products, and the electrical connection relationship therebetween is also a mature technology, which will not be described in detail here.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
