Description

Technical Field

[0001] The utility model relates to a voltage stabilizing control device, in particular to a direct current power supply wide range voltage regulating and stabilizing control device, belonging to the technical field of direct current power supply. Background Art

[0002] In the prior art, for example, the invention with application number 202311414565.X discloses a control device for a DC power supply. In order to solve the problem that the existing DC power supply control device needs to be protected and dissipated by a cooling fan during use to prevent the DC circuit control device from being damaged or overheated during use, however, when using a cooling fan for heat dissipation, it is necessary to ensure air flow inside and outside the device, which makes the device susceptible to humid weather, thereby causing the internal circuit to short-circuit. The hair dryer conveys external air to the interior of the protection box, and the exhaust fan discharges the air inside the protection box. The internal heat dissipation part blows air to the control device position inside the protection box for heat dissipation. The air conveyed by the hair dryer needs to pass through the drying box position before entering the protection box. A desiccant is placed inside the drying box. The desiccant can be any drying structure, which mainly plays a drying role, dries the moisture in the air, ensures that dry air enters the interior of the protection box, and avoids the accumulation of water vapor inside the protection box, thereby avoiding the failure of the control device due to humidity, avoiding the short circuit of the internal circuit of the control device, and ensuring the normal operation of the control device.

[0003] Similar to the above application, there are still some shortcomings:

[0004] The desiccant has a certain service life, so during the use of the device, the desiccant needs to be replaced regularly, which is troublesome and increases the cost of use. In addition, when the ambient temperature is high, the heat dissipation effect of the device is poor;

DETAILED DESCRIPTION

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides a DC power supply wide range voltage regulation and stabilization control device, including a protection box 1, a control device 2 stored in the protection box 1, and a box cover 3 covering the top of the protection box 1, a mounting groove 4 is opened in the middle of the box cover 3, a collar 5 is rotatably installed in the mounting groove 4, the outer side of the collar 5 is in contact with the inner wall of the mounting groove 4, the top and bottom of the collar 5 are both provided with a mesh pad layer 7, the inside of the collar 5 is filled with a silica gel desiccant 8, a middle partition 6 is fixed in the middle position of the collar 5 to evenly separate the silica gel desiccant 8, and the inner top of the mounting groove 4 is in contact with the inner wall of the mounting groove 4. The bottom is provided with a supporting protrusion 9, which is attached to the surface of the mesh pad layer 7. Upper air grooves 10 connected to the outside of the protection box 1 are opened at both ends of the top of the installation groove 4, and lower air grooves 11 connected to the inside of the protection box 1 are opened at both ends of the bottom of the installation groove 4. An axle rod 12 fixedly connected to the top of the middle partition 6 is rotatably installed at the middle position of the top of the box cover 3. A cooling fan 13 is installed at one end of the protection box 1, and the input end of the cooling fan 13 is connected to the upper air groove 10. A refrigeration mechanism 14 is provided at one end of the protection box 1 away from the cooling fan 13 and at the end of another group of upper air grooves 10.

[0025] The general working principle: when the device is installed and used, the middle partition plate 6 on the collar 5 is aligned with the position of the supporting protrusion 9. At this time, the interior of the installation groove 4 is divided, one end of the installation groove 4 is connected to the air inlet end, and the other end of the installation groove 4 is connected to the exhaust end. During the air intake process, the heat dissipation fan 13 is started to extract the hot air inside the protection box 1 from the upper air groove 10 at one end of the protection box 1, and the upper air groove 10 at the other end absorbs external air. After the external air enters the interior of the installation groove 4, it is dehumidified by the silica gel desiccant 8 at one end of the collar 5, and the silica gel desiccant 8 at the other end of the collar 5 is placed at the exhaust end, and the hot air passes through it. After the device is used for a long time, the silica gel desiccant 8 near the air inlet end is filled with moisture and loses the dehumidification effect. At this time, the collar 5 is rotated by the shaft 12, and the positions of the silica gel desiccant 8 at the two ends of the collar 5 are swapped, and the silica gel desiccant 8 is restored by hot air to ensure the normal use of the device. At the same time, there is no need to replace the silica gel desiccant 8, and the service life of the device is longer.

[0026] In this embodiment, an adjusting disk is fixed to the top end of the shaft 12, and anti-slip grooves are provided on the outer side of the adjusting disk.

[0027] Partial working principle: During the rotation of the collar 5, due to the existence of the adjustment disk, the rotation of the shaft 12 can be directly controlled manually, and the operation is more convenient.

[0028] In this embodiment, the top of the control device 2 is in contact with the bottom of the box cover 3 , and the lower air grooves 11 are respectively located at two ends of the control device 2 .

[0029] Partial working principle: The control device 2 can provide a certain barrier to the gas inside the protection box 1. After the outside air enters the protection box 1, it flows through both sides of the control device 2, thereby ensuring the cooling effect.

[0030] In this embodiment, a vertical plate 15 is vertically installed at one end of the bottom of the box cover 3 away from the heat dissipation fan 13, and the vertical plate 15 extends to the inner bottom of the protective box 1. A cavity 16 is opened inside the vertical plate 15, and air holes 18 connected to the inside of the cavity 16 are evenly opened on the inner side of the vertical plate 15. A guide pipe 17 is installed between the inner side of the vertical plate 15 and the end of the lower air groove 11, and the lower air groove 11 is connected to the inside of the cavity 16 through the guide pipe 17.

[0031] Local working principle: After the outside air enters the interior of the installation groove 4, it will enter the interior of the cavity 16 through the lower air groove 11 and the guide pipe 17 at the bottom, and then be evenly discharged from the interior of the cavity 16, ensuring that different positions of the control device 2 can be evenly cooled, and the cooling effect is better.

[0032] In this embodiment, the air holes 18 are evenly distributed on the vertical plate 15 in a rectangular array, and the inner side of the vertical plate 15 is parallel to the end surface of the control device 2 .

[0033] Partial working principle: Through the use of multiple groups of air holes 18, the heat dissipation effect is guaranteed during use.

[0034] In this embodiment, the refrigeration mechanism 14 includes a mounting block 19, a through groove 20 and a semiconductor refrigerator 21. The mounting block 19 is fixed to the end of the protective box 1. The mounting block 19 is provided with a through groove 20 which is connected to the upper air groove 10. The semiconductor refrigerator 21 is installed at the inner bottom of the through groove 20, and the cold end of the semiconductor refrigerator 21 is located inside the through groove 20.

[0035] Partial working principle: When the external environment temperature is high, the semiconductor refrigerator 21 is turned on, and the gas entering the protection box 1 will first pass through the inside of the through groove 20 to cool down, ensuring that the device can effectively cool down under different ambient temperatures.

[0036] In this embodiment, a heat dissipation port connected to the bottom of the mounting block 19 is provided below the semiconductor cooler 21, the hot end of the semiconductor cooler 21 faces the heat dissipation port, and an exhaust fan 22 is installed inside the heat dissipation port.

[0037] Partial working principle: A certain amount of hot air will be generated at the hot end of the semiconductor refrigerator 21, and the exhaust fan 22 will be used to discharge the hot air to the outside to prevent the hot air from affecting the heat dissipation.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
