It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0027] See also Figure 1 The embodiment of the present invention provides a Ku-band up-conversion power amplifier, the Ku-band up-conversion power amplifier comprising: a detachable cover 10, the detachable cover 10 is provided with dust-proof heat dissipation holes 11, the detachable cover 10 is bolted to the top of a shell 20; the shell 20, a power amplification component (not shown) is arranged inside the shell 20, the shell 20 comprises an input side 21, an output side 22 and a heat dissipation side 23, the input side 21 is arranged opposite to the output side 22; the heat dissipation side 23 is provided with the dust-proof heat dissipation holes 11 and the cooling heat dissipation holes 24, a ventilation device (not shown) is arranged on the inner wall of the shell corresponding to the cooling heat dissipation holes 24, the ventilation device is arranged above the power amplification component, and the wind direction of the ventilation device is from outside to inside.

[0028] In a possible implementation manner, in order to achieve dustproof and cooling effects for the Ku-band up-conversion power amplifier, its housing is improved. In this embodiment, the Ku-band up-conversion power amplifier includes a detachable cover 10 and a housing 20. The detachable cover 10 is bolted to the top of the housing 20, and a dustproof and heat dissipation hole 11 is provided on the detachable cover 10. Since the dustproof and heat dissipation hole 11 is often arranged upward, it is easy for dust to enter the Ku-band up-conversion power amplifier, so a protective design is required.

[0029] See also Figure 2 In an embodiment of the present invention, the removable cover body 10 includes an embedding groove 12, the opening of the embedding groove 12 is located at the heat dissipation side 23, the dustproof net 30 is embedded in the removable cover body 10 along the embedding groove 12, and a through hole 31 is set on the dustproof net 30. The through hole 31 is coaxial with the screw hole on the removable cover body 10, and the dustproof net 30 is arranged below the dustproof heat dissipation hole 11.

[0030] In actual application, in the prior art, the heat dissipation holes on the top of the up-conversion power amplifier are through holes. Although a dustproof net is provided to prevent dust from directly entering the up-conversion power amplifier, the accumulation of dust on the dustproof net will gradually lead to the closure of the dustproof net, thereby reducing the heat dissipation effect and failing to meet actual needs. Therefore, technicians expect to be able to block dust to a certain extent at the heat dissipation holes to increase the service life of the dustproof net while ensuring sufficient heat dissipation performance.

[0031] See also Figure 3 , is a cross-sectional schematic diagram of the dustproof and heat dissipation hole 11 provided in an embodiment of the present invention. In the embodiment of the present invention, the dustproof and heat dissipation hole 11 includes a dust shield plate 111 and an inclined groove structure 112, and the inclined groove structure 112 includes symmetrically arranged L-shaped inclined plates; the dust shield plate 111 is integrally arranged with the removable cover body 10 and is flush with the surface of the removable cover body 10, one end of the L-shaped inclined plate is connected to the removable cover body 10, and the other end extends obliquely toward the interior of the shell 20, and the end projection of the inclined groove structure 112 is located in the dust shield structure 111.

[0032] In a possible implementation, in order to effectively block dust on the top of the up-conversion power amplifier, the heat dissipation holes on the top are structurally improved. Specifically, the top of the removable cover 10 is subjected to punching and material extension treatments to form a plurality of L-shaped bevel pieces on the top of the removable cover 10, wherein every two symmetrically arranged L-shaped bevel pieces constitute a bevel groove structure 112, and the original portion of the removable cover 10 between the two L-shaped bevel pieces forms a dust shield 111. During the extension process, the length of the L-shaped bevel piece is extended so that the projection of its end is located within the dust shield structure 111.

[0033] During the implementation process, on the one hand, the dust can be blocked by the dust shield; on the other hand, when the dust falls into the surface of the L-shaped inclined plate from the hole between the L-shaped inclined plate and the dust shield 111, it is blocked by the surface of the L-shaped inclined plate and deposited. Since the end projection of the L-shaped inclined plate is located in the dust shield structure 111, the dust in the vertical direction will be completely blocked and deposited by the L-shaped inclined plate, thereby achieving preliminary blocking of the dust.

[0034] On the other hand, the housing 20 is also improved to further improve the dustproof and heat dissipation capabilities of the up-conversion power amplifier. In actual application, an input interface is set on the input side 21 of the housing 20; and an output interface is set on the output side 22. For example, the front and rear sides of the housing 20 are the input side 21 and the output side 22, respectively, and the left and right sides are the heat dissipation sides 23. In order to improve the heat dissipation effect, heat dissipation fins can be set in the empty area of ​​the input side 21. The heat dissipation side 23 is provided with dustproof heat dissipation holes 11 and cooling heat dissipation holes 24, and a ventilation device is set in the area corresponding to the cooling heat dissipation holes 24 on the inner wall of the housing. The ventilation device is, for example, a fan, which is set above the power amplification component, and the wind direction of the fan is from outside to inside.

[0035] During the application process, the fan is powered on and operated, so that the external air is brought into the up-conversion power amplifier through the cooling and heat dissipation holes 24. Due to the internal pressure, the incoming air is blown out from the dust-proof heat dissipation holes 11 on the top and sides to take away the heat inside the up-conversion power amplifier; at the same time, in the process of air escaping outward, due to the blocking effect of the dust shield 111, return air will be formed at the inclined groove structure 112. In the process of the return air flowing outward through the L-shaped inclined plate, the dust deposited on the L-shaped inclined plate will be taken away, thereby achieving the cleaning of the L-shaped inclined plate and preventing excessive dust deposition from falling into the interior of the up-conversion power amplifier. At the same time, when the fan blows the interior of the up-conversion power amplifier, it will also lift up the internal dust and blow it out through the dust-proof heat dissipation holes 11, thereby achieving the cleaning of the surface of the power amplifier component, achieving the improvement of its surface cleanliness while dissipating heat, and ensuring the best heat dissipation capacity.

[0036] In an embodiment of the present invention, by improving the heat dissipation holes of the up-conversion power amplifier, a dust-proof heat dissipation hole 11 with dust blocking and enrichment effects is adopted, and in combination with a fan inside the up-conversion power amplifier, internal dust enrichment can be effectively reduced, maintaining the best heat dissipation effect while having sufficient ventilation and heat dissipation capabilities.

[0037] However, in actual applications, the conventional practice of setting heat dissipation holes on the side of the up-conversion power amplifier is often to set circular through holes. During use, on the one hand, the circular through holes do not have a dust-proof effect. When a fan is used to blow air inward, the circular through holes will serve as a channel for dust to enter the interior of the up-conversion power amplifier, causing dust to accumulate inside the up-conversion power amplifier; on the other hand, the circular through holes do not have a cooling ability. When the external ambient temperature is high, the air blown in from the outside by the fan has no obvious cooling effect, resulting in the temperature inside the up-conversion power amplifier still being too high, and therefore unable to meet actual needs.

[0038] In order to solve the above technical problems, in an embodiment of the present invention, the heat dissipation side 23 includes a first area where the cooling and heat dissipation holes 24 are set and a second area where the dust-proof heat dissipation holes 11 are set, and the dust-proof heat dissipation holes are arranged around the cooling and heat dissipation holes.

[0039] For further information, see Figure 3 , is a cross-sectional schematic diagram of a cooling and heat dissipation hole 24 provided in an embodiment of the present invention. In the embodiment of the present invention, the thickness of the first area is greater than the thickness of the second area; the cooling and heat dissipation hole 24 includes an inlet section 241, a middle section 242 and an outlet section 243, the inlet section 241 is located on the outside of the shell 20, and the outlet section 243 is located on the inside of the shell 20, and the inlet section 241 and the outlet section 243 are both canyon structures.

[0040] In actual application, the heat dissipation side 23 is divided into two areas, wherein the first area is provided with a cooling and heat dissipation hole 24, and the second area is provided with a dust-proof heat dissipation hole 11, and the thickness of the first area is set to be greater than the thickness of the second area. At this time, the cooling and heat dissipation hole 24 is improved. Specifically, the cooling and heat dissipation hole 24 includes an inlet section 241, a middle section 242 and an outlet section 243, thereby forming a through hole with a canyon structure at the front and back. When the fan is running, the external air is sucked into the up-conversion power amplifier through the cooling and heat dissipation hole 24.

[0041] During the circulation process, the air first passes through the canyon structure of the inlet section 241. Since the passage of the air gradually decreases during the circulation process, on the one hand, the dust and impurity particles in the air will collide with the inclined surface of the inlet section 241 and settle, thereby achieving a self-cleaning effect on the air; on the other hand, when the air flows along the inclined surface, a turbulent flow will be formed, which will further interfere with the air entering the middle section 242, so that the dust and impurity particles therein are disturbed and settled, thereby improving the cleaning effect on the air; on the third hand, when the air passes through the canyon structure, it will be squeezed and produce a weak compression effect, and heat will be released during the compression process. When entering the outlet section 243 after passing through the middle section 242, the outlet section 243 is a gradually open structure. At this time, the compressed air will be expanded, thereby absorbing the heat in the air, so that the air can absorb and take away more heat after entering the up-conversion power amplifier, and finally be discharged from the dust-proof heat dissipation hole 11 with heat. According to actual implementation data, the internal temperature of the up-conversion power amplifier using the embodiment of the present invention is 0.5-3° lower than the external temperature, that is, a stronger heat dissipation performance is achieved.

[0042] In the embodiment of the present invention, by adopting heat dissipation holes with a cooling effect, on the one hand, the air entering the up-conversion power amplifier can be automatically cleaned, which greatly reduces the enrichment of dust and impurity particles mixed in the air inside the up-conversion power amplifier, and ensures the best heat dissipation performance; on the other hand, by compressing and expanding the air, the air entering the up-conversion power amplifier has a stronger cooling effect, further improving its heat dissipation performance and meeting actual needs.

[0043] It is easy for technical personnel in this field to know that the higher the power of a fan, the greater the power consumption, but the better the cooling effect. In different scenarios, technicians have different requirements for heat dissipation performance. Therefore, in order to meet personalized needs, the physical parameters of the fan and the cooling and heat dissipation holes 24 can be configured according to actual energy consumption requirements and heat dissipation performance requirements.

[0044] In the embodiment of the present invention, the inlet section 241 and the outlet section 243 are both arranged according to a preset inclination, and the diameter of the middle section 242 and the preset inclination are inversely proportional to the power of the ventilation device.

[0045] Specifically, for scenarios with higher power consumption requirements, a low-power fan can be configured. In this case, the inclination of the inlet section 241 and the outlet section 243 is increased, and the diameter of the middle section 242 is increased to achieve optimal heat dissipation performance. For scenarios with higher heat dissipation requirements, a high-power fan can be configured. In this case, the inclination of the inlet section 241 and the outlet section 243 is reduced, and the diameter of the middle section 242 is reduced to amplify the compression and expansion effects on the air and improve its heat dissipation performance, thereby meeting personalized needs.

[0046] However, in actual application, since the heat dissipation side is composed of two oppositely arranged side sides, a fan is arranged on each side. If they are arranged opposite to each other, the wind force will produce a certain degree of offsetting effect, reducing the compression effect of the air when entering the cooling and heat dissipation hole 24, thereby affecting the actual heat dissipation performance.

[0047] See also Figure 4 In the embodiment of the present invention, the heat dissipation side 23 includes a first side 231 and a second side 232, the first side 231 includes a first cooling and heat dissipation hole, the second side 232 includes a second cooling and heat dissipation hole, the first cooling and heat dissipation hole is arranged close to the input side 21, and the second cooling and heat dissipation hole is arranged close to the output side 22, and the projections of the first cooling and heat dissipation hole and the second cooling and heat dissipation hole on the vertical section do not overlap.

[0048] In a possible implementation, the cooling and heat dissipation holes on the relatively arranged heat dissipation side edges 23 are staggered, and thus the corresponding fans are also staggered. During the implementation process, on the one hand, the wind input by the two fans does not directly confront each other, thereby avoiding affecting the actual power of the fan input air; on the other hand, by staggering the fans, when the air hits the opposite side and flows back, the two airflows interact with each other to form vortices, which can achieve the adsorption effect on dust and impurity particles in the up-conversion power amplifier, and can more effectively roll up large particles of impurities deposited in the up-conversion power amplifier and discharge them through the dust-proof and heat dissipation holes 11 on the top or side, thereby effectively improving the cleanliness of the inside of the up-conversion power amplifier, while improving the efficiency of removing internal heat and improving the heat dissipation performance.

[0049] In the embodiment of the present invention, a plurality of dustproof and heat dissipation holes 11 are arranged on the top of the detachable cover 10, and all the dustproof and heat dissipation holes 11 on the detachable cover 10 are radially arranged on the detachable cover 10 with the preset hole as the center.

[0050] Furthermore, in an embodiment of the present invention, a first ventilation device (not shown) is provided on the first side 231, and a second ventilation device (not shown) is provided on the second side 232. The first ventilation device and the second ventilation device form a wind field, and the center of the preset hole coincides with the center of the wind field.

[0051] In the specific implementation process, due to the two relatively and staggered fans, a cyclone will be formed in the up-conversion power amplifier during the blowing process. The center of the cyclone has the greatest wind force, and the greater the heat dissipation capacity and impurity removal capacity, the farther away from the center of the cyclone, the smaller the wind force, and the heat dissipation capacity and impurity removal capacity decrease. Therefore, by arranging the dust-proof and heat-dissipating holes 11 radially on the detachable cover 10, and the center of the dust-proof and heat-dissipating holes 11 coincides with the center of the wind field, the heat dissipation capacity and impurity removal capacity of the wind field can be maximized, and the maximum heat dissipation performance and cleaning performance can be achieved, thereby meeting the actual needs of up-conversion power amplifiers, especially high-power up-conversion power amplifiers.

[0052] Furthermore, an embodiment of the present invention also provides a satellite communication device, which includes the Ku-band up-conversion power amplifier according to the embodiment of the present invention.

[0053] The optional implementation modes of the embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited to the specific details in the above implementation modes. Within the technical concept of the embodiments of the present invention, various simple modifications can be made to the technical scheme of the embodiments of the present invention, and these simple modifications all belong to the protection scope of the embodiments of the present invention.

[0054] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the present invention will not further describe various possible combinations.

[0055] In addition, various implementation modes of the embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the embodiments of the present invention, they should also be regarded as the contents disclosed by the embodiments of the present invention.
