Description

Technical Field

[0001] The utility model relates to the field of shielded power supplies, and more specifically, to a shielded power supply with a strong anti-interference structure. Background Art

[0002] Currently, since UPS power supplies usually use frequency modulation inversion, they will generate high-frequency radiation, which has a high-frequency interference effect on computers and their peripheral devices, and will affect the normal operation of the host computer's display. Therefore, the power supply needs to be placed at a certain distance from the computer and the display, which is inconvenient to install, takes up space, and will also generate electromagnetic wave interference, which is not conducive to the overall operation of the equipment.

[0003] After retrieval, in the prior art, a Chinese patent with the patent application number 201720439527.3 discloses an anti-interference UPS power supply, including a housing, a power core body, and a heat dissipation air duct structure. It is characterized in that a shielding layer and a heat sink layer are sequentially wrapped on the outer wall surface of the power core body. The shielding layer is composed of an anti-static layer and an aluminum foil layer stacked in sequence, and the heat sink layer is wrapped on the outer wall surface of the aluminum foil layer. However, there are still the following defects:

[0004] (1) In the above patent document, a metal shielding cover is used as the main shielding structure for power supply anti-interference. However, the ventilation openings left at the ventilation openings of the power supply will reduce the anti-interference performance of the power supply. When the power supply is installed near devices with a high density of electronic components such as motherboards, the ventilation openings will leak some high-frequency radiation, causing interference to electronic devices and affecting their normal operation.

[0005] (2) In the above patent document, the core body of the power supply is cooled by using a cooling fan and a heat dissipation air duct. However, in actual use, floating objects such as dust in the environment will be sucked into the heat dissipation air duct by the cooling fan. If the dust accumulates continuously in the heat dissipation air duct, it will reduce the heat dissipation effect of the power supply, and the dust accumulation may also cause static electricity, resulting in a failure of the power core body.

[0006] Therefore, we make improvements on this and propose a shielded power supply with a strong anti-interference structure. Summary of the Utility Model

[0007] The object of the present utility model is as follows: Currently, a metal shielding cover is used as the main shielding structure for power supply anti-interference. However, the ventilation openings left at the power supply ventilation ports will reduce the anti-interference performance of the power supply. When the power supply is installed near devices with a high density of electronic components such as a motherboard, the ventilation openings will leak some high-frequency radiation, causing interference to the electronic devices and affecting their normal operation. The heat dissipation of the power supply core is achieved by using a cooling fan and a cooling air duct. However, in actual use, floating objects such as dust in the environment will be sucked into the cooling air duct by the cooling fan. If the dust accumulates continuously in the cooling air duct, it will reduce the heat dissipation effect of the power supply, and the dust accumulation may also cause static electricity, resulting in faults in the power supply core.

[0021] 1. The power core body is completely surrounded by the provided aluminum shielding housing.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0031] AsFigure 1 , Figure 3 , Figure 4 and Figure 5 As shown in Figure 5 , this embodiment proposes a shielded power supply with a strong anti-interference structure, including a mounting rack 1 and a ventilation rack 11 fixedly connected and magnetically connected to the outer wall of the mounting rack 1. The ventilation racks 11 are symmetrically distributed about the central axis of the mounting rack 1. It further includes:

[0032] A shielding component, detachably connected to the inner wall of the mounting rack 1 for shielding power radiation and anti-interference. Among them, the shielding component includes an aluminum shielding shell 2 detachably connected to the inner wall of the mounting rack 1, a mounting slide rail 21 fixedly connected to the outer wall of the aluminum shielding shell 2, a fixing rack 22 fixedly connected to the inner wall of the aluminum shielding shell 2, a power core 23 arranged inside the aluminum shielding shell 2, and a connecting rack 24 fixedly connected to the outer wall of the power core 23. The aluminum shielding shell 2 is a completely sealed structure and is filled with insulating and heat-conducting silicone oil inside. The aluminum shielding shell 2 is quickly disassembled and assembled with the mounting rack 1 through the mounting slide rail 21. The connecting rack 24 and the fixing rack 22 are connected by bolts;

[0033] A heat exchange component, fixedly connected to the outer wall of the shielding component for transferring the heat generated by the power supply during operation;

[0034] A flow guiding component, fixedly connected to the outer wall of the shielding component for accelerating the heat exchange speed;

[0035] A ventilation component, fixedly connected to the inner wall of the ventilation rack 11 for quickly cooling the heat exchange component;

[0036] A transmission component, fixedly connected to the inner wall of the shielding component for input and output of electric energy;

[0037] Since aluminum metal has good ability to shield electromagnetic radiation, the aluminum shielding shell 2 is used to completely surround the power core 23, and the electromagnetic radiation generated during the operation of the power core 23 is shielded in all directions, avoiding interference with other electronic components in the environment.

[0038] As Figure 1 , Figure 3 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the heat exchange component includes a diversion tube 3 fixedly connected to the outer wall of the aluminum shielding shell 2, a heat dissipation fin 31 fixedly connected to the output end of the diversion tube 3, and a diversion cavity 32 arranged inside the heat dissipation fin. The diversion cavity 32 is connected to the inside of the aluminum shielding shell 2 through the diversion tube 3. When the power core 23 operates, heat is inevitably generated, and the heat-conducting silicone oil filled in the aluminum shielding shell 2 will absorb and conduct the heat on the surface of the power core 23.

[0039] As Figure 2 andFigure 4 As shown, as a preferred embodiment, on the basis of the above method, further, the diversion component includes a magnetic induction motor 4 fixedly connected to the outer wall of the aluminum shielding housing 2 and a magnetic induction stirring turbine 41 rotatably connected to the inner wall of the aluminum shielding housing 2. The magnetic induction motor 4 is directly above the magnetic induction stirring turbine 41. The magnetic induction motor 4 drives the magnetic induction stirring turbine 41 to rotate inside the aluminum shielding housing 2. During the heat dissipation process, the magnetic induction motor 4 is started, and the magnetic induction motor 4 drives the magnetic induction stirring turbine 41 to rotate, so that the heat-conducting silicone oil inside the aluminum shielding housing 2 flows into the heat dissipation fins 31 through the diversion pipe 3. After the heat-conducting silicone oil is dissipated through the heat dissipation fins 31, it then flows back into the aluminum shielding housing 2 through the diversion pipe 3, completing the overall heat dissipation of the shielding power supply.

[0040] As Figure 1 As shown, as a preferred embodiment, on the basis of the above method, further, the ventilation component includes a heat dissipation motor 5 fixedly connected to the inner wall of the ventilation frame 11 and a heat dissipation fan 51 fixedly connected to the output end of the heat dissipation motor 5. The heat dissipation motors 5 are symmetrically distributed about the central axis of the ventilation frame 11. When the power core 23 has a high load and generates a large amount of heat, the heat dissipation motor 5 is started to drive the heat dissipation fan 51 to rotate. The heat dissipation fan 51 rotates to generate a high-speed airflow to quickly dissipate heat from the heat dissipation fins 31 and the heat-conducting silicone oil therein, preventing dust from being brought into the shielding device or deposited on the surface of the power core 23 when the heat dissipation fan 51 actively dissipates heat from the shielding power supply, which may affect the heat dissipation effect and cause potential safety hazards.

[0041] As Figure 1 、 Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the transmission component includes an input connector 62 fixedly connected to the inner wall of the aluminum shielding housing 2, an output connector 6 fixedly connected to the inner wall of the aluminum shielding housing 2, an input wire 63 fixedly connected to the input end of the input connector 62, and an output wire 61 fixedly connected to the output end of the output connector 6. The input connector 62 and the output connector 6 extend outward through the inner wall of the aluminum shielding housing 2. The input connector 62 and the output connector 6 are fixedly connected to the power core 23 and are sealed with respect to the aluminum shielding housing 2. Before use, the output wire 61 and the input wire 63 are connected to the corresponding power-consuming units and power-consuming units to ensure the safety of power use.

[0042] Specifically, when this device is in use: Since aluminum has good ability to shield electromagnetic radiation, the aluminum shielding shell 2 is used to completely surround the power core 23, providing an all-round shielding for the electromagnetic radiation generated during the operation of the power core 23, thus avoiding interference with other electronic components in the environment. When the power core 23 operates, heat is inevitably generated. The heat-conducting silicone oil filled in the aluminum shielding shell 2 will absorb and conduct the heat on the surface of the power core 23. During the heat dissipation process, the magnetic induction motor 4 is started. The magnetic induction motor 4 drives the magnetic induction stirring turbine 41 of the device to rotate, causing the heat-conducting silicone oil inside the aluminum shielding shell 2 to flow into the heat dissipation fins 31 through the diversion pipe 3. After the heat-conducting silicone oil is dissipated through the heat dissipation fins 31, it flows back into the aluminum shielding shell 2 through the diversion pipe 3, completing the overall heat dissipation of the shielded power supply. When the power core 23 has a high load and generates a large amount of heat, the heat dissipation motor 5 is started to drive the heat dissipation fan 51 to rotate. The rotation of the heat dissipation fan 51 generates a high-speed air flow to quickly dissipate heat from the heat dissipation fins 31 and the heat-conducting silicone oil therein, preventing dust from being brought into the shielding device or deposited on the surface of the power core 23 during the active heat dissipation of the shielded power supply, which may affect the heat dissipation effect and cause potential safety hazards. Before use, the output wire 61 and the input wire 63 are connected to the corresponding power-consuming units and power-consuming units to ensure the safety of power use.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
