[0026] The filter assembly 6 comprises clamping grooves 61 symmetrically arranged on the mounting frame one 5, the mounting frame one 5 is provided with a plug hole 62, the plug hole 62 is in communication with the clamping grooves 61, the mounting frame one 5 is clamped with a filter plate 63, the filter plate 63 is symmetrically fixed with a mounting plate 64, the mounting plate 64 is clamped with the clamping grooves 61, the surface of the mounting plate 64 is provided with an annular groove 65, the mounting plate 64 is fixedly provided with a fixed block 66, the both sides of the fixed block 66 are fixedly connected with springs 67, the end side of the springs 67 is fixedly provided with a fixed rod 68, the side wall of the fixed rod 68 is fixedly provided with a plug rod 69, the fixed rod 68 is fixedly provided with a push rod 610, and the push rod 610 is slidably connected with the annular groove 65.

[0027] In the present embodiment: during the operation of the phase modifier, the external cold air enters from the mounting frame one 5 under the action of the fan, passes through the filter assembly 6, and then flows through the air path channel formed by the lower ventilation cover 2 and the upper ventilation cover 3 to the phase modifier body 1, thereby taking away the heat generated during the operation of the phase modifier, and finally being discharged from the mounting frame two 7, so as to realize the cooling and temperature reduction of the phase modifier. The existence of the reinforcing ribs 4 ensures the structural stability of the lower ventilation cover 2 and the upper ventilation cover 3 under the impact of airflow, ensures the smoothness of the air path, and improves the cooling efficiency. ​

[0028] When installing the filter plate 63, first manually press the push rod 610, so that the two push rods 610 slide along the arc-shaped groove, when the push rod 610 slides, because the push rod 610 is fixedly connected with the fixed rod 68, and the fixed rod 68 is fixedly connected with the plug rod 69, so during pushing, the fixed rod 68 and the plug rod 69 slide synchronously into the cavity in the mounting plate 64, and press the spring 67, so that the plug rod 69 enters the cavity in the mounting plate 64, then the operator aligns the mounting plate 64 on both sides of the filter plate 63 with the clamping groove 61 on the mounting frame one 5, and then slowly pushes the mounting plate 64 into the clamping groove 61, when the mounting plate 64 is clamped with the clamping groove 61, at this time, the pressing on the push rod 610 is released, the spring 67 is released from the mortgage, and the spring 67 drives its reset by using its elastic property, the spring 67 pushes the fixed rod 68 to move outward under the action of the elastic force, so that the plug rod 69 is inserted into the plug hole 62, thereby fixing the mounting plate 64 in the clamping groove 61, and completing the installation of the filter plate 63.

[0030] When the filter plate 63 needs to be cleaned or replaced after being used for a period of time, the operator pushes the push rod 610 with fingers, so that the push rod 610 slides along the annular groove 65 to the fixed block 66, the push rod 610 drives the fixed rod 68 to move, the spring 67 is compressed, and the plug rod 69 is withdrawn from the plug hole 62, at this time, the operator can pull out the mounting plate 64 from the clamping groove 61, so as to take down the filter plate 63, when replacing a new filter plate 63 or a cleaned filter plate 63, the operation can be performed according to the installation principle, this structure design makes the disassembly and replacement of the filter plate 63 very convenient and fast, which can effectively reduce the maintenance time and cost.

[0031] Example two:

[0032] This embodiment aims to promote the solution to the problems of low air volume adjustment accuracy, local air volume imbalance during adjustment, and inability to accurately match the heat dissipation demand according to load changes of the existing phase modifier, this embodiment is an improvement based on example one, for details, please refer to Figure 1 - Figure 2 and Figure 5 The mounting frame two 7 is provided with an air volume adjustment assembly 8, the air volume adjustment assembly 8 comprises a plurality of rotating rods 88 rotatably connected to the mounting frame two 7, the rotating rods 88 are fixedly sleeved with blocking plates 89, the top surface of the mounting frame two 7 is fixedly provided with a mounting bracket 81, the mounting bracket 81 is fixedly provided with a motor 82, the output end of the motor 82 is fixedly connected with a screw rod 83, and the outer circle of the screw rod 83 is threadedly provided with a sliding rod 84.

[0033] The side wall of the mounting frame two 7 is fixed with a limiting plate 85, the sliding rod 84 slides along the limiting plate 85, the limiting plate 85 is provided with a clamping groove 61, the sliding rod 84 slides along the clamping groove 61, a guide rail is formed, the sliding rod 84 moves stably along a straight line, and deviation of the sliding rod 84 under the driving of the screw rod 83 is prevented, and the plurality of rotating rods 88 are provided with cranks 87 which are fixedly sleeved with the outer rings of the rotating rods 88, and the connecting columns 86 are fixedly connected with the sliding rod 84.

[0034] In the embodiment: when the screw rod 83 rotates under the driving of the motor 82, the sliding rod 84 moves linearly under the guidance of the limiting plate 85, the connecting column 86 drives the crank 87 to rotate through linkage, the rotating rod 88 rotates, the blocking plate 89 on the rotating rod 88 rotates synchronously, and the relative angle between the blocking plate 89 and the air outlet of the mounting frame two 7 is changed, so that the air volume of the air outlet is accurately adjusted, when different heat dissipation requirements are generated due to load changes of the phase modulation machine, the cooling air volume can be controlled by adjusting the angle of the blocking plate 89, and it is ensured that the equipment is always in a suitable operating temperature.

[0036] In the specific adjustment process, when the blocking plate 89 is parallel to the plane of the air outlet, the shielding area is smallest, the ventilation cross-sectional area is largest, and the air volume reaches the peak value; as the blocking plate 89 rotates, the included angle between the blocking plate 89 and the plane of the air outlet gradually increases, the shielding area synchronously increases, the ventilation cross-sectional area decreases, and the air volume decreases; when the blocking plate 89 is perpendicular to the plane of the air outlet, the shielding area is largest, the ventilation cross-sectional area is smallest, and the air volume is lowest. Through control of the rotation angle of the blocking plate 89, continuous stepless adjustment of the air volume from the minimum to the maximum can be realized, and the heat dissipation requirements of the phase modulation machine under different working conditions can be accurately matched.

[0037] It should be noted that, in the present document, the terms such as first and second, etc., are merely used to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
