Abstract
Description
Technical Field
[0001] This utility model belongs to the field of switching power supply technology, specifically relating to a switching power supply with rapid cooling. Background Technology
[0002] A fast-cooling switching power supply is an energy conversion device with an integrated high-efficiency heat dissipation design. It achieves rapid cooling by optimizing heat conduction and convection mechanisms. Its core principle lies in the rapid switching of high-frequency switching transistors in conjunction with energy storage components to complete energy conversion. Fast-cooling switching power supplies not only continue the advantages of traditional switching power supplies such as high efficiency, lightweight, and wide voltage adaptability, but also ensure stable operation of equipment through precise temperature control, avoiding performance degradation or component damage caused by high temperatures. Its application fields cover a wide range of high-power scenarios, such as industrial robots, CNC machine tools and other equipment that need to work continuously for a long time, as well as temperature-sensitive electronic systems such as communication base stations and servers.
[0003] Chinese Patent Publication No. CN222485138U discloses a rapid cooling switching power supply, relating to the field of switching power supply technology. It includes a housing and a power supply body, with the power supply body housed within the housing. A heat-conducting plate is mounted on the inner side of the housing, positioned above the power supply body. This rapid cooling switching power supply, through the combined use of the heat-conducting plate, heat sink, fixing posts, and positioning grooves, allows the heat-conducting plate to compress and limit the upper part of the power supply body under the action of a spring after the power supply body is fitted inside the housing. In this limited state, the fixing posts at the bottom of the heat-conducting plate embed into the positioning grooves on the power supply body, ensuring the stability of the power supply body within the housing. Simultaneously, the heat generated during operation can be transferred to the heat sink through the heat-conducting plate, increasing the contact area with air and achieving better heat dissipation.
[0004] In practical use, this utility model mainly relies on convective airflow to remove and dissipate heat. However, the cooling airflow of existing fast-cooling switching power supplies often blows in a single fixed direction, making it difficult for the airflow distribution to cover all heat-generating areas inside the power supply. This unbalanced heat dissipation method makes it impossible for local high-temperature areas to be effectively cooled, while some areas may waste energy due to over-cooling. Ultimately, this results in inconsistent overall heat dissipation efficiency, which significantly restricts the performance stability and environmental adaptability of fast-cooling switching power supplies in practical applications. Utility Model Content
[0005] This invention proposes a rapid cooling switching power supply to address the problem of difficulty in comprehensively and uniformly cooling switching power supplies in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling switching power supply, comprising:
[0007] Switching power supply body and mounting housing;
[0008] Multiple support rods are provided at the bottom of the mounting housing, the main body of the switching power supply is provided at the top of the multiple support rods, and a heat-conducting plate is provided inside the mounting housing, the heat-conducting plate abutting against the top of the main body of the switching power supply;
[0009] A threaded rod is rotatably connected to the upper end of the mounting housing. The upper end of the inner wall of the mounting housing is provided with a ventilation plate, and a ventilation groove is opened in the ventilation plate. Multiple air outlets are provided at the bottom end of the ventilation groove.
[0010] Two limiting grooves are respectively opened on both sides of the inner wall of the mounting shell. Both ends of the heat-conducting plate are provided with limiting plates that are adapted to the limiting grooves. The two limiting plates are respectively located in the two limiting grooves and are slidably connected to the side wall of the limiting groove.
[0011] In a preferred embodiment, the upper end of the heat-conducting plate is provided with multiple heat dissipation fins, all of which are serrated and have multiple heat dissipation grooves.
[0012] To ensure comprehensive and uniform cooling of the switching power supply, the ventilation plate is further provided with a threaded rod adapted to the threaded rod. The threaded rod passes through the threaded hole and is threadedly connected to the side wall of the threaded hole. A servo motor is provided on one side of the upper end of the mounting shell, and one end of the threaded rod is located on the output end of the servo motor.
[0013] In a preferred embodiment, the upper end of the ventilation plate is provided with multiple rectangular grooves, and each of the multiple rectangular grooves is rotatably connected with an abutting wheel, the upper ends of the multiple abutting wheels abutting against the upper end of the inner wall of the mounting shell.
[0014] In a preferred embodiment, an air pump is provided on one side of the mounting housing, and a telescopic hose is provided at the air outlet of the air pump. The other end of the telescopic hose extends through the mounting housing into the interior and is connected to the ventilation slot.
[0015] In a preferred embodiment, each of the two limiting plates is provided with a limiting rod at its upper end, and the upper ends of the two limiting rods extend outward through the two limiting grooves respectively, and are provided with the same driving plate.
[0016] In a preferred embodiment, a limiting spring is sleeved on the outer side of each of the two limiting rods, with the two ends of the limiting spring respectively located on one side of the limiting groove and the limiting plate.
[0017] To facilitate the installation or removal of the switching power supply, multiple support rods extend through the mounting shell to the outside at one end and are provided with the same mounting plate, which is connected to the mounting shell by multiple fixing bolts.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. This utility model, through a reciprocating ventilation plate and multiple air outlets set inside the mounting housing, allows cold air to flexibly cover all heat-generating areas inside the switching power supply. Combined with multiple serrated heat dissipation fins on the upper part of the heat-conducting plate, it not only increases the heat exchange area, but also guides the airflow through the zigzag fins to form a turbulent effect, effectively breaking the thermal boundary layer and promoting the rapid conduction of heat to the flowing air. This allows the cooling airflow to fully penetrate the internal space of the power supply, avoiding local overheating or cooling dead zones, thereby significantly improving the uniformity of temperature distribution and making the fast-cooling switching power supply more practical.
[0020] 2. This utility model, through multiple detachable support rods set at the bottom of the mounting housing, not only enables quick disassembly and maintenance of the switching power supply, but also, when the power supply is supported, the support rods naturally form a suspended structure at the bottom, which effectively increases the air circulation space and avoids heat accumulation caused by direct contact with the mounting surface. Thus, while ensuring structural stability, it also improves heat dissipation efficiency, allowing the power supply to maintain a suitable operating temperature during continuous operation. This satisfies the dual requirements of convenient installation and heat dissipation performance, providing a reliable guarantee for the long-term stable operation of the equipment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example 1:
[0028] Please see Figure 1-4 This utility model provides a fast-cooling switching power supply, comprising:
[0029] The main body of the switching power supply 1 and the mounting shell 2;
[0030] Multiple support rods 3 are all set at the bottom of the mounting shell 2, and the main body of the switching power supply 1 is set at the top of the multiple support rods 3. A heat-conducting plate 4 is provided inside the mounting shell 2, and the heat-conducting plate 4 abuts against the top of the main body of the switching power supply 1.
[0031] A threaded rod 5 is rotatably connected to the upper end of the mounting shell 2. A ventilation plate 6 is provided on the upper end of the inner wall of the mounting shell 2. A ventilation groove is opened in the ventilation plate 6. Multiple air outlets 7 are provided at the bottom end of the ventilation groove.
[0032] Two limiting grooves are respectively opened on both sides of the inner wall of the mounting shell 2. Both ends of the heat conduction plate 4 are provided with limiting plates 8 that are adapted to the limiting grooves. The two limiting plates 8 are located in the two limiting grooves respectively and are slidably connected to the side wall of the limiting groove.
[0033] Specifically, such as Figure 2 and Figure 3 As shown, the upper end of the heat-conducting plate 4 is provided with multiple heat dissipation fins 9, all of which are serrated and have multiple heat dissipation grooves 10. The multiple serrated heat dissipation fins 9 and the multiple heat dissipation grooves 10 on their surfaces can increase the heat exchange area. Furthermore, the zigzag heat dissipation fins 9 guide the airflow to form a turbulence effect, effectively breaking the thermal boundary layer and promoting the rapid conduction of heat to the flowing air, so that the heat dissipation airflow can fully penetrate the internal space of the power supply.
[0034] Specifically, such as Figure 2 and Figure 4 As shown, the ventilation plate 6 is provided with a threaded rod 5 that is adapted to the threaded rod 5. The threaded rod 5 passes through the threaded hole and is threadedly connected to the side wall of the threaded hole. A servo motor 11 is provided on one side of the upper end of the mounting shell 2. The servo motor 11 is existing technology and will not be described in detail here. One end of the threaded rod 5 is set on the output end of the servo motor 11.
[0035] Through its design, when the servo motor 11 starts, its output end will drive the threaded rod 5 to rotate, and the threaded rod 5 will drive the ventilation plate 6 and multiple air outlets 7 to move, so that the air used for cooling can be blown evenly on the switching power supply body 1 and multiple heat dissipation fins 9, effectively improving the efficiency and uniformity of cooling the switching power supply body 1.
[0036] Specifically, such as Figure 2 and Figure 4 As shown, the upper end of the ventilation plate 6 is provided with multiple rectangular grooves, and each of the multiple rectangular grooves is rotatably connected with abutting wheels 12. The upper ends of the multiple abutting wheels 12 are all abutted against the upper end of the inner wall of the mounting shell 2. The multiple rotatable abutting wheels 12 can make the ventilation plate 6 move more smoothly.
[0037] Specifically, such as Figure 3 As shown, an air pump 13 is provided on one side of the mounting housing 2. The air pump 13 is existing technology and will not be described in detail here. The air outlet end of the air pump 13 is provided with a telescopic hose 14. The other end of the telescopic hose 14 passes through the mounting housing 2 and extends into the interior, and is connected to the ventilation slot. The telescopic hose 14 allows the ventilation plate 6 to be in different positions so that the air used for cooling can be introduced into the ventilation slot, ensuring the stability of cooling of the switching power supply.
[0038] Specifically, such as Figure 1 and Figure 2 As shown, each of the two limiting plates 8 is provided with a limiting rod 15 at its upper end. The upper ends of the two limiting rods 15 extend to the outside through the two limiting grooves respectively, and are provided with the same driving plate 16. The driving plate 16 can drive the two limiting rods 15 to move up and down synchronously, thereby driving the two limiting plates 8 and the heat-conducting plate 4 to move up and down.
[0039] Specifically, such as Figure 2 As shown, limit springs 17 are sleeved on the outer sides of both limit rods 15. The two ends of the limit springs 17 are respectively set on the limit groove and the limit plate 8. The limit springs 17 can limit the position of the limit plate 8, so that the heat conduction plate 4 can always be pressed against the upper end of the switching power supply body 1. This not only ensures the cooling effect, but also limits its position, preventing the switching power supply body 1 from shifting during use.
[0040] Example 2:
[0041] Please see Figure 1-4 This utility model provides a fast-cooling switching power supply, comprising:
[0042] The main body of the switching power supply 1 and the mounting shell 2;
[0043] Multiple support rods 3 are all set at the bottom of the mounting shell 2, and the main body of the switching power supply 1 is set at the top of the multiple support rods 3. A heat-conducting plate 4 is provided inside the mounting shell 2, and the heat-conducting plate 4 abuts against the top of the main body of the switching power supply 1.
[0044] The threaded rod 5 is rotatably connected to the upper end of the mounting shell 2. The upper end of the inner wall of the mounting shell 2 is provided with a ventilation plate 6. A ventilation groove is opened in the ventilation plate 6, and multiple air outlets 7 are provided at the bottom end of the ventilation groove.
[0045] Two limiting grooves are respectively opened on both sides of the inner wall of the mounting shell 2. Both ends of the heat conduction plate 4 are provided with limiting plates 8 that are adapted to the limiting grooves. The two limiting plates 8 are located in the two limiting grooves respectively and are slidably connected to the side wall of the limiting groove.
[0046] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, one end of each of the multiple support rods 3 extends through the mounting shell 2 to the outside and is provided with the same mounting plate 18. The mounting plate 18 is connected to the mounting shell 2 by multiple fixing bolts 19.
[0047] Through its design, by using multiple support rods 3 and mounting plate 18 set at the bottom of the mounting shell 2, the switching power supply body 1 can be quickly disassembled and maintained by moving multiple support rods 3. This not only allows the bottom of the switching power supply body 1 to be suspended, but also effectively increases the air circulation space and avoids heat accumulation caused by direct contact with the mounting surface. Thus, while ensuring structural stability, it also improves the heat dissipation efficiency.
[0048] See Figure 1-4 When using a fast-cooling switching power supply, the main body 1 of the switching power supply needs to be placed inside the mounting shell 2, and its position is supported by moving multiple support rods 3. The heat-conducting plate 4 inside the mounting shell 2 will press against the upper end of the main body 1 of the switching power supply under the action of the limiting spring 17, which can limit its position. When cooling the main body 1 of the switching power supply, the servo motor 11 and the air pump 13 need to be started. The output end of the servo motor 11 will drive the threaded rod 5 to rotate. The threaded rod 5 will drive the ventilation plate 6 and multiple air outlets 7 to move towards one side of the mounting shell 2. The air pump 13 will introduce air into the ventilation groove in the ventilation plate 6 through the telescopic hose 14, and blow it onto the serrated heat dissipation fins 9 through the multiple air outlets 7. This can evenly and comprehensively cool down the heat generated by the main body 1 of the switching power supply, avoid local overheating or cooling dead zones, and make the fast-cooling switching power supply more practical.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
