Description

Technical Field

[0001] The utility model relates to the field of heat dissipation devices, and particularly relates to a heat dissipation device for a regulated power supply. Background Art

[0002] A regulated power supply is an electronic device that can provide a stable alternating current or direct current for a load, including two categories: an AC regulated power supply and a DC regulated power supply. When there is an instantaneous fluctuation in the grid voltage or load, the regulated power supply will compensate for the voltage amplitude at a response speed of 10 - 30 ms, making it stable within ±2%.

[0003] The Chinese invention patent with the publication number CN214177176U discloses a heat dissipation mechanism for a DC regulated power supply, including a housing. A plurality of heat dissipation holes are evenly distributed on the left and right vertical end walls of the housing. Legs are welded at the four corners of the bottom of the housing. A through groove is opened at the center position of the bottom of the housing, and a fan is arranged below the through groove, and the fan is bolt - fixedly connected to the housing.

[0004] However, the above - mentioned patent has the following deficiencies:

[0005] 1. The above - mentioned patent controls the opening and closing of the through groove and the heat dissipation holes through a mechanical structure to ensure that no impurities enter the interior of the housing when the regulated DC power supply is not in use, improving the safety of the device. However, when the device is in normal use, dust will still enter the interior of the device. At the same time, if filters are simply installed on the through groove and the heat dissipation holes, a large amount of dust will cover the filters after the device has been used for a long time, thus affecting the heat dissipation of the device.

[0006] 2. The above - mentioned device does not have a quick - disassembly structure, so it is not convenient enough when installing or disassembling the power supply. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a heat dissipation device for a regulated power supply. By using a self - cleaning filtering mechanism, it can prevent external dust from entering the interior of the device while the heat dissipation mechanism is started to dissipate heat inside the device through flowing air. At the same time, the device can automatically clean the dust on the surface of the filter screen, so as to prevent the dust from blocking the filter screen and affecting the heat dissipation effect of the device, in order to solve the above - mentioned deficiencies in the technology.

[0008] To achieve the above purpose, the utility model provides the following technical solution: A heat dissipation device for a regulated power supply, including a base, a heat dissipation mechanism, an installation mechanism, and a self - cleaning filtering mechanism;

[0009] A plurality of first through holes are provided on both sides of the top of the base. An installation cylinder is provided on the top of the base. A support rod is fixedly connected between the base and the installation cylinder. An installation plate is provided inside the installation cylinder, and the side wall of the installation plate is fixedly connected to the inner wall of the installation cylinder;

[0010] The heat dissipation mechanism is arranged inside the installation cylinder and is used to improve the heat dissipation efficiency of the device;

[0011] The self-cleaning filtering mechanism is arranged on the outer periphery of the installation cylinder and is used to prevent dust from entering the device. At the same time, the self-cleaning filtering mechanism has the function of self-cleaning;

[0012] The installation mechanism is arranged between the installation cylinder and the self-cleaning filtering mechanism and is used for the installation between the installation cylinder and the self-cleaning filtering mechanism.

[0013] Preferably, the heat dissipation mechanism includes an air inlet groove and an air outlet groove; the air inlet groove is opened on one side of the installation cylinder, the air outlet groove is opened on the other side of the installation cylinder, an air inlet fan is provided on one side of the air inlet groove, the side wall of the air inlet fan is fixedly connected to the inner wall of the installation cylinder, an air outlet fan is provided on one side of the air outlet groove, and the side wall of the air outlet fan is fixedly connected to the inner wall of the installation cylinder;

[0014] By starting the air inlet fan, air can be introduced into the installation cylinder through the air inlet groove. At the same time, by starting the air outlet fan, the air in the installation cylinder can be discharged, so that the air can circulate in the installation cylinder, and the heat inside the installation cylinder can be taken away by the air, so as to achieve the effect of dissipating heat from the voltage stabilizer power supply.

[0015] Preferably, the installation mechanism includes a fixing rod, the fixing rod is U-shaped in reverse, both ends of the fixing rod are fixedly connected with connecting plates, and a plurality of second through holes are opened on the surface of the connecting plates, and the second through holes correspond to the first through holes;

[0016] Because the first through hole corresponds to the second through hole, a bolt can penetrate through the first through hole and the second through hole and be fixed to the installation surface, so that the fixing between the connecting plate and the base and the fixing between the device and the installation surface can be completed at the same time.

[0017] Preferably, the self-cleaning filtering mechanism includes an annular storage groove, a sealing cylinder and a stepping motor. The annular storage groove is arranged inside the installation cylinder, and both the air inlet groove and the air outlet groove are communicated with the annular storage groove,

[0018] The side wall of the stepping motor is fixedly connected with the fixing rod, the output shaft of the stepping motor is fixedly connected with a fixing sleeve, and a first fixing hole is opened on the outer periphery of the fixing sleeve;

[0019] The sealing cylinder is movably connected to the annular receiving groove, and filter nets are arranged on both sides of the sealing cylinder. Both the air inlet groove and the air outlet groove are matched with the filter nets;

[0020] A fixed shaft is fixedly connected to the front side of the sealing cylinder. A second fixing hole is formed in the middle of the fixed shaft. The fixed shaft and the fixed sleeve are detachably connected by bolts;

[0021] The fixed shaft and the fixed sleeve can be installed or disassembled by bolts, so as to facilitate the disassembly of the sealing cylinder connected to the fixed shaft, and thus facilitate the cleaning of the surface of the sealing cylinder.

[0022] After the fixed shaft and the fixed sleeve are fixed, by starting the stepping motor, the fixed shaft and the sealing cylinder can be driven to rotate through the fixed sleeve. By controlling the rotation angle of the sealing cylinder, it can be controlled whether the filter nets outside the sealing cylinder coincide with the air inlet groove and the air outlet groove;

[0023] When the two filter nets coincide with the air inlet groove and the air outlet groove respectively, both the air inlet groove and the air outlet groove are covered by the filter nets. Therefore, dust in the outside world will be blocked by the filter nets and cannot enter the device;

[0024] When the filter net on one side of the air inlet groove is used for too long, its outer surface will be covered with dust, which will affect the air intake volume of the device and then reduce the heat dissipation effect of the device. At this time, by rotating the sealing cylinder by a certain degree, the two filter nets can be swapped. At this time, the filter net on one side of the air outlet groove will be swapped to one side of the air inlet groove. Because this filter net was previously on one side of the air outlet groove and the air blows from the inside to the outside of the filter net, there will be no dust accumulation on its outer surface. At the same time, when the filter net previously on one side of the air inlet groove is on one side of the air outlet groove, since the air blows from the inside to the outside of the filter net, the dust covering the outside of the filter net will also be blown away, so that the self-cleaning of the filter net can be completed;

[0025] When the two filter nets do not coincide with the air inlet groove and the air outlet groove, the inner wall of the sealing cylinder will close the air inlet groove and the air outlet groove. At this time, the inside of the device will be completely in a closed state, so as to prevent external fluid impurities from entering the device;

[0026] Preferably, a first scraping plate is arranged inside the air inlet groove. The side wall of the first scraping plate is fixedly connected to the inner wall of the air inlet groove. A second scraping plate is arranged inside the air outlet groove. The side wall of the second scraping plate is fixedly connected to the inner wall of the air outlet groove;

[0027] Both the first scraping plate and the second scraping plate are matched with the filter nets;

[0028] By arranging a first scraper in the air inlet groove and a second scraper in the air outlet groove, when the sealing cylinder drives the two filters on its outer side to rotate, both the first scraper and the second scraper will scrape the dust on the surface of the filter, which is beneficial to improving the cleaning efficiency of the dust on the surface of the filter.

[0029] Preferably, a buffer cotton is fixedly connected to the bottom of the base, and the buffer cotton is made of sponge material;

[0030] By arranging the buffer cotton, after the base is fixed on the installation surface, the buffer cotton will fill the pores between the base and the installation surface, so as to avoid the vibration generated after the inlet fan and the outlet fan start, causing the device to shake and generate noise.

[0031] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0032] 1. By using the self-cleaning filter mechanism, it is possible to prevent external dust from entering the device while the heat dissipation mechanism is started to dissipate heat inside the device through flowing air, and at the same time, the device can automatically clean the dust on the surface of the filter, so as to prevent the dust from blocking the filter and affecting the heat dissipation effect of the device;

[0033] 2. By arranging the installation mechanism, it is convenient to disassemble the self-cleaning filter mechanism, so as to facilitate the cleaning of the self-cleaning filter mechanism, and at the same time, it is also convenient to install or disassemble the regulated power supply inside the device.

[0060] The working principle of this utility model:

[0061] Refer to the attached drawings of the specification Figures 1-4, when the device is in use, first, the regulated power supply can be fixed on the mounting plate 14 inside the mounting cylinder 12. Then, the end of the mounting cylinder 12 can be inserted into the annular receiving groove 41. After that, the fixing sleeve 44 can be sleeved outside the fixing shaft 47 fixedly connected to the mounting cylinder 12, and then the mounting cylinder 12 and the fixing shaft 47 can be fixed to each other by bolts. At this time, the second through hole 33 on the surface of the connecting plate 32 will be aligned with the first through hole 11 on the surface of the base 1. At this time, a bolt can be passed through the first through hole 11 and the second through hole 33 and fixed to the mounting surface, so as to complete the fixation between the connecting plate 32 and the base 1, as well as the fixation between the device and the mounting surface at the same time;

[0062] Refer to the attached Figures 1-4 , when the device is in use, by starting the stepper motor 43, the fixing shaft 47 and the sealing cylinder 42 can be driven to rotate through the fixing sleeve 44. By controlling the rotation angle of the sealing cylinder 42, it can be controlled whether the filter screens 46 outside the sealing cylinder 42 coincide with the air inlet groove 21 and the air outlet groove 22;

[0063] When the two filter screens 46 coincide with the air inlet groove 21 and the air outlet groove 22 respectively, both the air inlet groove 21 and the air outlet groove 22 are covered by the filter screens 46. Therefore, dust in the outside world will be blocked by the filter screens 46 and cannot enter the device;

[0064] When the filter screen 46 on one side of the air inlet groove 21 has been used for a long time, its outer surface will be covered with dust, which will affect the air intake volume of the device and then reduce the heat dissipation effect of the device. At this time, by rotating the sealing cylinder 42 by 180 degrees, the two filter screens 46 can be swapped. At this time, the filter screen on the side of the air outlet groove 22 will be swapped to the side of the air inlet groove 21. Because this filter screen 46 was previously on the side of the air outlet groove 22 and the air blows from the inside to the outside of the filter screen 46, there will be no dust accumulation on its outer surface. At the same time, when the filter screen 46 previously on the side of the air inlet groove 21 is on the side of the air outlet groove 22, due to the air blowing from the inside to the outside of the filter screen 46, the dust covering the outside of the filter screen 46 will also be blown away, so as to complete the self-cleaning of the filter screen 46;

[0065] When the two filter screens 46 do not coincide with the air inlet groove 21 and the air outlet groove 22, the inner wall of the sealing cylinder 42 will close the air inlet groove 21 and the air outlet groove 22. At this time, the inside of the device will be completely in a closed state, so as to prevent external fluid impurities from entering the device;
