Description

Technical Field

[0001] This utility model relates to the field of switching power supply technology, and in particular to a high-efficiency switching power supply heat dissipation device. Background Technology

[0002] A switching power supply uses a circuit to control a switching transistor to switch on and off at high speed, converting direct current into high-frequency alternating current to supply a transformer for voltage transformation, thereby generating one or more sets of voltages as needed. Currently, when using a switching power supply, it generates a lot of heat, requiring heat dissipation to ensure its normal operation.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Existing high-efficiency switching power supply heat dissipation devices generally adopt the design of installing a fan on the surface of the switching power supply and opening heat dissipation holes to achieve a cooling effect. However, the heat dissipation holes are easily blocked by dust. When cleaning, due to the complexity of the internal structure of the switching power supply and its difficulty in disassembly, the dust on the surface of the heat dissipation holes is often only wiped. The dust during wiping aggravates the internal dust accumulation, and the accumulation of dust will seriously affect the ventilation and heat dissipation efficiency of the switching power supply. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the heat dissipation holes in the existing technology are easily blocked by dust. When cleaning, due to the complexity of the internal structure of the switching power supply and its difficulty in disassembly, the dust is often only wiped off the surface of the heat dissipation holes. However, the dust during wiping aggravates the internal dust accumulation, which seriously affects the ventilation and heat dissipation efficiency of the switching power supply. Therefore, we propose a high-efficiency switching power supply heat dissipation device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a high-efficiency switching power supply heat dissipation device, comprising a high-efficiency switching power supply body, a first heat dissipation device installed on one side of the high-efficiency switching power supply body, placement slots on both sides of the high-efficiency switching power supply body, a second heat dissipation device slidably connected inside the placement slots, a second sliding groove on both sides of the second heat dissipation device, two storage slots on both sides of the interior of the high-efficiency switching power supply body, a T-shaped block slidably connected inside the storage slots, the surface of the T-shaped block slidably connected to the interior of the second sliding groove, two return springs fixed on one side of the T-shaped block, the other end of the return springs fixedly connected to one side of the interior of the storage slot, a rotating block rotatably connected inside the storage slot, two through slots on both sides of the high-efficiency switching power supply body, a cylinder fixedly connected to one side of the rotating block, the surface of the cylinder rotatably connected to the interior of the through slot, a connecting block slidably connected inside the cylinder, and a knob fixed on one side of the connecting block.

[0006] Preferably, two first sliding grooves are provided on both sides of the high-efficiency switching power supply body, and a first slider is fixed on one side of the knob, with the surface of the first slider slidably connected to the inside of the first sliding groove.

[0007] Preferably, a tension spring is fixed to one side of the connecting block, and the other end of the tension spring is fixedly connected to one side of the inside of the cylinder.

[0008] Preferably, a first limiting groove is provided on both sides of the inside of the cylinder, and a first limiting block is fixed on both sides of the connecting block, and the surface of the first limiting block is slidably connected to the inside of the first limiting groove.

[0009] Preferably, the inner diameter of the first groove is adapted to the outer diameter of the surface of the first slider.

[0010] Preferably, two second limiting grooves are provided on both sides of the inside of the storage groove, and two second limiting blocks are fixed on both sides of the T-shaped block, with the surface of the second limiting block slidably connected to the inside of the second limiting groove.

[0011] Preferably, the rotating block has an arc-shaped perimeter.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, rotating the knob causes a fixed connecting block on one side to rotate. When the connecting block rotates, it causes the cylinder to rotate, which in turn causes a fixed rotating block on one side to rotate. When the rotating block rotates, it releases the pushing force on the T-shaped block, allowing the surface of the T-shaped block to be pulled back to its initial position by the tension of two return springs. When the surface of the T-shaped block is released from the interior of the second slide groove, the second heat dissipation device can be removed. After removing the second heat dissipation device, its surface is cleaned before it is installed inside the placement groove. This allows for quick installation and fixation of the second heat dissipation device, preventing the heat dissipation holes from being directly opened on the surface of the high-efficiency switching power supply body. This avoids the inability to clean the internal heat dissipation holes, which would cause a large amount of dust to accumulate inside the holes, resulting in poor ventilation and heat dissipation of the high-efficiency switching power supply body.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a high-efficiency switching power supply heat dissipation device, including a high-efficiency switching power supply body 1, a first heat dissipation device 2 installed on one side of the high-efficiency switching power supply body 1, placement slots 3 on both sides of the high-efficiency switching power supply body 1, a second heat dissipation device 4 slidably connected inside the placement slots 3, a second sliding groove 20 on both sides of the second heat dissipation device 4, two storage slots 5 on both sides of the interior of the high-efficiency switching power supply body 1, a T-shaped block 6 slidably connected inside the storage slot 5, the surface of the T-shaped block 6 slidably connected to the interior of the second sliding groove 20, two return springs 8 fixed on one side of the T-shaped block 6, the other end of the return spring 8 fixedly connected to one side of the interior of the storage slot 5, a rotating block 7 rotatably connected inside the storage slot 5, two through slots 9 on both sides of the high-efficiency switching power supply body 1, a cylinder 10 fixedly connected to one side of the rotating block 7, the surface of the cylinder 10 rotatably connected to the interior of the through slot 9.

[0023] A connecting block 11 is slidably connected inside the cylinder 10. A knob 12 is fixed on one side of the connecting block 11. First, rotate the knob 12 to drive the fixed connecting block 11 to rotate. When the connecting block 11 rotates, it will drive the cylinder 10 to rotate. When the cylinder 10 rotates, it will drive the fixed rotating block 7 to rotate. When the rotating block 7 rotates, it will release the pushing force on the T-shaped block 6, so that the surface of the T-shaped block 6 will be pulled back to its original position by the tension of the two return springs 8. When the surface of the T-shaped block 6 is released from the inside of the second slide groove 20, the second heat dissipation device 4 can be removed. When the second heat dissipation device 4 is removed, the surface of the second heat dissipation device 4 is cleaned before it is installed inside the placement groove 3. This allows the second heat dissipation device 4 to be quickly installed and fixed, avoiding the heat dissipation holes being directly opened on the surface of the high-efficiency switching power supply body 1, which would prevent the internal heat dissipation holes from being cleaned and causing a large amount of dust to accumulate inside the heat dissipation holes, resulting in poor ventilation and heat dissipation of the high-efficiency switching power supply body 1.

[0024] Reference Figure 4 and Figure 5 As shown in this embodiment: two first slide grooves 13 are opened on both sides of the high-efficiency switching power supply body 1. A first slider 14 is fixed on one side of the knob 12. The surface of the first slider 14 is slidably connected to the inside of the first slide groove 13. When the user rotates the knob 12 to drive the rotating block 7 to rotate, so that the rotating block 7 pushes the surface of the T-shaped block 6 to move into the inside of the second slide groove 20, the rotating block 7 will not rotate due to shaking by inserting the surface of the first slider 14 into the inside of the first slide groove 13.

[0025] Reference Figure 4 and Figure 5 As shown in this embodiment: a tension spring 15 is fixed on one side of the connecting block 11, and the other end of the tension spring 15 is fixedly connected to one side of the inside of the cylinder 10. When the user inserts the surface of the first slider 14 into the inside of the first groove 13, the tension of the tension spring 15 causes the knob 12 to drive the first slider 14 to have a continuous force to one side, so as to prevent the surface of the first slider 14 from being dislodged from the inside of the first groove 13 due to shaking.

[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: a first limiting groove 16 is provided on both sides of the inside of the cylinder 10, and a first limiting block 17 is fixed on both sides of the connecting block 11. The surface of the first limiting block 17 is slidably connected to the inside of the first limiting groove 16. When the user moves the knob 12, it will drive the fixed connecting block 11 on one side to move. The inside of the first limiting groove 16 has a limiting effect on the surface of the first limiting block 17, so that the surface of the connecting block 11 will not be pulled out of the inside of the cylinder 10.

[0027] Reference Figure 4 and Figure 5 As shown in this embodiment: the inner diameter of the first groove 13 is adapted to the outer diameter of the surface of the first slider 14. When the user inserts the surface of the first slider 14 into the inside of the first groove 13, the inner diameter of the first groove 13 is adapted to the outer diameter of the surface of the first slider 14, thus preventing the rotating block 7 from rotating slightly.

[0028] Reference Figure 3 and Figure 5 As shown in this embodiment: two second limiting grooves 18 are opened on both sides of the inside of the storage slot 5, and two second limiting blocks 19 are fixed on both sides of the T-shaped block 6. The surface of the second limiting block 19 is slidably connected to the inside of the second limiting groove 18. When the user rotates the knob 12 to drive the rotating block 7 to rotate, the rotating block 7 generates a pushing force on the T-shaped block 6 or releases the pushing force on the T-shaped block 6. The limiting effect of the inside of the second limiting groove 18 on the surface of the second limiting block 19 prevents the T-shaped block 6 from deviating when moving.

[0029] Reference Figure 3 and Figure 5 As shown in this embodiment, the rotating block 7 has an arc shape around its perimeter. By making the rotating block 7 arc-shaped, a greater frictional force can be generated when the rotating block 7 contacts one side of the T-shaped block 6 during rotation, making the rotation smoother for the user.

[0030] Working principle: Step 1, first rotate knob 12 to make knob 12 drive the fixed connecting block 11 on one side to rotate. When the connecting block 11 rotates, it will drive cylinder 10 to rotate. When cylinder 10 rotates, it will drive the fixed rotating block 7 on one side to rotate. When rotating block 7 rotates, it will release the pushing force on T-shaped block 6, so that the surface of T-shaped block 6 will be pulled back to its initial position by the tension of two return springs 8. When the surface of T-shaped block 6 is released from the inside of the second slide groove 20, the second heat dissipation device 4 can be removed. When the second heat dissipation device 4 is removed,

[0031] By cleaning the surface of the second heat dissipation device 4 and then installing the surface of the second heat dissipation device 4 inside the placement slot 3, the second heat dissipation device 4 can be quickly installed and fixed, avoiding the heat dissipation holes being directly opened on the surface of the high-efficiency switching power supply body 1, which would prevent the internal heat dissipation holes from being cleaned.

[0032] Step two: By inserting the surface of the first slider 14 into the interior of the first groove 13, the rotating block 7 will not rotate due to shaking. The tension of the tension spring 15 causes the knob 12 to drive the first slider 14 to have a continuous force to one side, preventing the surface of the first slider 14 from detaching from the interior of the first groove 13 due to shaking. The interior of the first limiting groove 16 limits the surface of the first limiting block 17, preventing the surface of the connecting block 11 from being pulled out of the interior of the cylinder 10. The inner diameter of the first groove 13 matches the outer diameter of the surface of the first slider 14, preventing the rotating block 7 from rotating slightly. The interior of the second limiting groove 18 limits the surface of the second limiting block 19, preventing the T-shaped block 6 from shifting during movement. The arc shape of the rotating block 7 allows for greater friction when it contacts one side of the T-shaped block 6 during rotation.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
