Description

Technical Field

[0001] This utility model relates to the field of high-frequency power module technology, specifically to a mounting box for a high-frequency power module with heat dissipation function. Background Technology

[0002] In modern electronic devices, high-frequency power modules are widely used in communications, industrial automation, power, and other fields. During operation, high-frequency power modules generate a significant amount of heat. If this heat cannot be dissipated effectively and promptly, the module temperature will rise, affecting its performance and stability, and potentially shortening its lifespan.

[0003] Currently, many common high-frequency power module mounting boxes on the market employ relatively simple heat dissipation methods, relying solely on natural cooling or simple ventilation holes. When high-frequency power modules generate significant power and heat, these methods are insufficient to meet cooling requirements, leading to module failure due to overheating. Meanwhile, some mounting boxes using forced air cooling suffer from inadequate airflow organization, resulting in insufficient and inefficient heat dissipation as airflow cannot effectively remove the heat generated by the power module. Utility Model Content

[0004] In view of this, the present invention provides a mounting box for a high-frequency power module with heat dissipation function, which aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mounting box for a high-frequency power module with heat dissipation function, comprising:

[0006] The housing has a horizontal partition inside, which divides the housing into an installation cavity and an air supply cavity from top to bottom.

[0007] A support plate is disposed inside the mounting cavity and parallel to the partition plate, and a power module body is provided on the support plate;

[0008] A horizontal plate is disposed in the air-generating chamber and parallel to the partition plate. The horizontal plate and the partition plate form an air storage chamber. An air extraction port is provided on the horizontal plate, and an exhaust fan is provided in the air extraction port. The exhaust fan rotates under the drive of a motor. An exhaust port is provided at the top of the mounting chamber, and an exhaust fan is provided in the exhaust port. When the exhaust fan rotates, the exhaust fan is driven to rotate synchronously through the connecting assembly. An air inlet is provided on one side of the air-generating chamber below the horizontal plate.

[0009] Two oppositely arranged jet pipes have their lower ends passing through the partition and connected to the air storage chamber, and their upper ends passing through the support plate. The two oppositely arranged jet pipes are provided with multiple jet nozzles, which face the power module body.

[0010] A further improvement of this utility model is that the connecting component includes:

[0011] The first rotating shaft is located in the air-generating cavity below the horizontal plate. Its upper end is fixedly connected to the exhaust fan, and its lower end is fixedly connected to the output end of the motor. A first bevel gear is fixedly mounted on it.

[0012] The second rotating shaft is rotated inside the air-generating cavity and is parallel to the first rotating shaft. A second bevel gear is fixedly provided at the lower end of the second rotating shaft, and a third bevel gear is fixedly provided at the upper end of the second rotating shaft after passing through the horizontal plate, partition plate and support plate.

[0013] The third rotating shaft is horizontally mounted inside the air-generating chamber, and two fourth bevel gears fixed at its two ends mesh with the first bevel gear and the second bevel gear, respectively.

[0014] The fourth rotating shaft is rotatably installed in the mounting cavity, with its upper end fixedly connected to the exhaust fan and its lower end fixedly provided with the fifth bevel gear;

[0015] The fifth rotating shaft is horizontally mounted in the mounting cavity, and two sixth bevel gears fixed at its two ends mesh with the third bevel gear and the fifth bevel gear, respectively.

[0016] A further improvement of this utility model is that a filter plate is provided on the air inlet.

[0017] A further improvement of this utility model is that the filter plate is detachably disposed at the air inlet via a quick-release assembly.

[0018] A further improvement of this utility model is that the quick-release assembly includes:

[0019] A tray, located on the lower outer side of the housing, is used to hold the filter plate;

[0020] The pressure plate is slidably mounted on the upper outer side of the housing at the air inlet.

[0021] The screw is connected at its lower end to the shaft of the pressure plate and at its upper end to the support plate on the housing. After passing through the support plate, it is equipped with a wheel. When the screw rotates, it drives the pressure plate to move closer to or away from the upper end of the filter plate.

[0022] A further improvement of this utility model is that the jet nozzle is fan-shaped, with its smaller end connected to the jet pipe and its larger end facing the power module body.

[0023] A further improvement of this utility model is that the power module body is mounted on the support plate by bolts, the support plate is provided with a plurality of spaced elongated slots, and the bolts pass through the mounting holes and elongated slots on the power module body and are screwed into the nuts.

[0026] This invention provides a mounting box for a high-frequency power module with heat dissipation function. An exhaust fan draws external air into the air-generating chamber through the air inlet. After passing through the air storage chamber, the air is blown onto the power module body through the nozzle on the jet pipe, directly dissipating heat from the power module body. At the same time, the exhaust fan rotates synchronously under the drive of the connecting components, expelling the hot air in the mounting chamber from the exhaust port, forming a good air circulation. Compared with the prior art, this invention can achieve efficient heat dissipation, effectively reduce the temperature of the power module body, and ensure its stable operation.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.

[0036] This utility model provides a mounting box for a high-frequency power module with heat dissipation function, as detailed in the attached instruction manual. Figure 1 To be continued Figure 5 It can be seen that a high-frequency power module mounting box with heat dissipation function mainly includes the following parts or components: box body 10, support plate 12, horizontal plate 14, and air jet pipe 16.

[0037] In this invention, a horizontal partition 11 is provided inside the housing 10, dividing the housing 10 into an installation cavity and an air-generating cavity from top to bottom; a support plate 12 is provided in the installation cavity and is parallel to the partition 11, and a power module body 13 is provided on the support plate 12; a horizontal plate 14 is provided in the air-generating cavity and is parallel to the partition 11, forming an air storage cavity 15 with the partition 11, and an air extraction port 141 is provided on the horizontal plate 14, with an exhaust fan 142 installed inside the exhaust port 141, which rotates under the drive of a motor 143. The top of the mounting cavity is provided with an exhaust port 101, and an exhaust fan 102 is provided inside the exhaust port 101. When the exhaust fan 142 rotates, the exhaust fan 102 is driven to rotate synchronously through the connecting component 20. An air inlet 103 is provided on one side of the air-generating cavity below the horizontal plate 14. The lower ends of the two oppositely arranged jet pipes 16 pass through the partition plate 11 and are connected to the air storage cavity 15. The upper ends pass through the support plate 12 respectively. Multiple jet nozzles 161 are provided on the two oppositely arranged jet pipes 16, and the jet nozzles 161 face the power module body 13.

[0038] When the high-frequency power module body 13 starts working and generates heat, the motor 143 is started. The rotation of the motor 143 drives the exhaust fan 142 to rotate. When the exhaust fan 142 rotates, a negative pressure is formed at the air intake 141. Under the action of the air pressure difference, the outside air enters the air control chamber from the air inlet 103. The air entering the air control chamber flows towards the horizontal plate 14 under the action of the exhaust fan 142, and then enters the air storage chamber 15 formed by the horizontal plate 14 and the partition 11. The air in the air storage chamber 15 has a certain pressure. It is then passed through two jets that are arranged opposite each other and whose lower ends are connected to the air storage chamber 15. The air jet pipe 16 emits air from multiple nozzles 161 facing the power module body 13, ensuring a more even airflow across the surface of the power module body 13. This removes heat generated during operation, directly dissipating heat from the power module body 13. When the exhaust fan 142 rotates, it drives the exhaust fan 102 to rotate synchronously via the connecting assembly 20. The exhaust fan 102 creates suction at the exhaust port 101, drawing the heated air from the mounting cavity out of the mounting box, completing the entire air circulation process. This achieves efficient heat dissipation, effectively reducing the temperature of the power module body 13 and ensuring its stable operation.

[0039] As one embodiment, in conjunction with the appendix to the specification Figure 3It can be seen that the connecting assembly 20 includes a first rotating shaft 21, which is located in the air-generating chamber below the horizontal plate 14. Its upper end is fixedly connected to the exhaust fan 142, and its lower end is fixedly connected to the output end of the motor 143. A first bevel gear 211 is fixedly mounted on it. A second rotating shaft 22 is rotatably mounted in the air-generating chamber and is parallel to the first rotating shaft 21. A second bevel gear 221 is fixedly mounted on the lower end of the second rotating shaft 22, and a third bevel gear 221 is fixedly mounted on the upper end of the second rotating shaft 22 after passing through the horizontal plate 14, the partition plate 11, and the support plate 12. 22; The third rotating shaft 23 is horizontally mounted in the air-generating chamber, and two fourth bevel gears 231 fixed at both ends of it mesh with the first bevel gear 211 and the second bevel gear 221 respectively; The fourth rotating shaft 24 is mounted in the mounting chamber, and its upper end is fixedly connected to the exhaust fan 102, and its lower end is fixedly mounted with a fifth bevel gear 241; The fifth rotating shaft 25 is horizontally mounted in the mounting chamber, and two sixth bevel gears 251 fixed at both ends of it mesh with the third bevel gear 222 and the fifth bevel gear 241 respectively.

[0040] Motor 143 drives the first rotating shaft 21, which is fixedly connected to its output end, to rotate. The first bevel gear 211 on the first rotating shaft 21 meshes with the fourth bevel gear 231 at one end of the third rotating shaft 23, causing the third rotating shaft 23 to rotate. The fourth bevel gear 231 at the other end of the third rotating shaft 23 then meshes with the second bevel gear 221 at the lower end of the second rotating shaft 22, causing the second rotating shaft 22 to rotate. The second rotating shaft 22 meshes with the sixth bevel gear 251 at one end of the fifth rotating shaft 25 through the third bevel gear 222, causing the fifth rotating shaft 25 to rotate. The sixth bevel gear 251 at the other end of the fifth rotating shaft 25 meshes with the fifth bevel gear 241, thereby causing the fourth rotating shaft 24 to rotate. The fourth rotating shaft 24 causes the exhaust fan 102 to rotate. The exhaust fan 102 rotates and forms suction at the exhaust port 101, which discharges the air heated by the power module body 13 in the mounting cavity out of the mounting box from the exhaust port 101, completing the entire air circulation process. Continuous air circulation removes the heat generated by the power module body 13, ensuring its stable operation at a suitable temperature.

[0041] As one embodiment, in conjunction with the appendix to the specification Figure 1 Appendix Figure 4 It is known that a filter plate 104 is provided on the air inlet 103. The filter plate 104 is detachably provided at the air inlet 103 via a quick-release assembly 30. The quick-release assembly 30 includes a support plate 31, which is provided on the housing 10 at the lower outer side of the air inlet 103 for placing the filter plate 104; a pressure plate 32 is slidably provided on the housing 10 at the upper outer side of the air inlet 103; the lower end of the screw 33 is connected to the rotating shaft of the pressure plate 32, and the upper end is threadedly connected to and passes through the support plate 34 on the housing 10, and is provided with a rotating wheel 331. When the screw 33 rotates, it drives the pressure plate 32 to move closer to or away from the upper part of the filter plate 104.

[0042] The filter plate 104 at the air inlet 103 filters the incoming air, blocking dust and other impurities to ensure clean air entering the installation box. When the filter plate 104 needs to be replaced, the quick-release assembly 30 allows for easy cleaning or replacement. The cleaning or replacement method is as follows: rotate the wheel 331, which drives the screw 33 to rotate. The screw 33 drives the pressure plate 32 to move upward, releasing the filter plate 104. Then, remove the filter plate 104 from the support plate 31 for cleaning or replacement. After cleaning or replacement, reinstall the filter plate 104 on the support plate 31 at the air inlet 103. Rotate the wheel 331 in the opposite direction, which drives the screw 33 to rotate. The screw 33 drives the pressure plate 32 to press and fix the filter plate 104.

[0043] As one embodiment, in conjunction with the appendix to the specification Figure 2 Appendix Figure 5 As can be seen, the nozzle 161 is fan-shaped, with its smaller end connected to the nozzle 16 and its larger end facing the power module body 13. The larger end facing the power module body 13 allows the ejected airflow to cover the surface of the power module body 13 more extensively. Compared to a nozzle of ordinary shape, the fan-shaped design allows the airflow to diffuse rapidly after leaving the nozzle 161, thereby increasing the contact area with the power module body 13 and ensuring that heat is carried away more efficiently. The fan-shaped structure helps to make the airflow more evenly distributed across the power module body 13. This uniform airflow distribution avoids the formation of localized high-temperature areas on the surface of the power module body 13, ensuring that the entire power module body 13 receives effective heat dissipation and improving the stability of the heat dissipation effect.

[0044] As one embodiment, in conjunction with the appendix to the specification Figure 5 It can be seen that the power module body 13 is mounted on the support plate 12 by bolts 122. The support plate 12 has multiple spaced elongated slots 121. The bolts 122 pass through the mounting holes and elongated slots 121 on the power module body 13 and are screwed to the nuts 123.

[0045] When installing the power module body 13, first place it on the support plate 12, roughly aligning the mounting holes on the power module body 13 with the elongated slots 121 on the support plate 12. Next, take the bolt 122 and thread it through the mounting holes on the power module body 13 and the corresponding elongated slots 121 on the support plate 12. The bolt 122 can slide to some extent within the elongated slots 121. Then, screw the nut 123 onto the protruding end of the bolt 122. Tighten the nut 123 gradually by manually or with a tool. During tightening, the force applied by the nut 123 is transmitted through the bolt 122 to the power module body 13 and the support plate 12, gradually reducing the gap between them and ultimately securing the power module body 13 firmly to the support plate 12. If the position of the power module body 13 needs adjustment, loosen the nut 123, allowing the bolt 122 to slide within the elongated slots 121. After repositioning, tighten the nut 123 again to secure it.

[0046] The design of the elongated slot 121 breaks the limitation of the traditional fixed hole position. Since the mounting hole positions and sizes of different specifications of power module bodies 13 are different, the mounting box can be adapted to various specifications of power module bodies 13 by sliding adjustment of the bolt 122 in the elongated slot 121. This greatly improves the universality and applicability of the mounting box, reduces the need to replace the mounting box due to changes in the specifications of the power module body 13, and reduces costs.

[0047] As one embodiment, in conjunction with the appendix to the specification Figure 1 It is evident that a closable sealed door 17 is provided on one side of the installation cavity. This facilitates the installation, inspection, and maintenance of the power module body 13 inside the installation cavity by the staff.
