[0039] Digital power supply is a type of digital power supply. It is a digital power supply system that manages and regulates the output of digital power supply by adopting digital signal processing technology and control algorithms. It has analog-to-digital conversion, digital processing, digital-to-analog conversion, communication and monitoring. Digital power supply can adjust the control strategy according to demand and is programmable, making it more flexible to use.

[0040] Digital power supplies have high-speed digital circuits, which consume relatively high power and generate a lot of heat. Furthermore, due to their programmability, as the power of the digital power supply increases during use, the heat generated will also gradually increase. Consequently, existing digital power supplies are often damaged during use due to poor heat dissipation.

[0041] The utility model provides a digital power supply.

[0042] See also Figure 1 、 Figure 2 、 Figure 3 In one embodiment of the present invention, the digital power supply includes:

[0043] The box body 100 is provided with a circuit board 200 inside, wherein the circuit board 200 has a built-in programmable program, and a user can adjust the digital power supply through the programmable program.

[0044] The operation panel 300 is installed on the box 100, wherein the operation panel 300 has a display screen 310, operation buttons 320 and a connection line insertion port 330, wherein the user can perform programming operations through the operation buttons 320, and the display screen 310 can be used to display the user's operation steps and program codes.

[0045] The centrifugal fan 400 is installed inside the box 100. The centrifugal fan 400 can draw gas into the fan along the axial direction of the fan. After the air is drawn into the fan, the blades use centrifugal force to accelerate it, thereby changing the direction of the air flow from axial to radial, and finally diffuse outward.

[0046] The auxiliary cooling assembly 500 includes an auxiliary cooling medium 510 fixedly mounted within the housing 100. The auxiliary cooling medium 510 is used to mount the centrifugal fan 400 and cool the air blown out by the centrifugal fan 400. Since the centrifugal fan 400 is mounted on the auxiliary cooling medium 510, when the centrifugal fan 400 draws air in, the air comes into contact with the auxiliary cooling medium 510, which cools the air. When the centrifugal fan 400 diffuses the air outward, the air diffused outward is cooled by the auxiliary cooling medium 510. Compared to air at room temperature, the cooled air in the housing 100 has a better heat dissipation effect on the digital power supply, thereby improving the heat dissipation of the digital power supply and preventing damage to the digital power supply due to poor heat dissipation. This solves the technical problems existing in the prior art. In this embodiment, the structure of the auxiliary cooling medium 510 is not specifically limited.

[0047] The technical solution of the present invention adopts an auxiliary cooling medium 510 and a centrifugal fan 400. When the centrifugal fan 400 draws in air, the air comes into contact with the auxiliary cooling medium 510. At this time, the auxiliary cooling medium 510 can cool the air. When the centrifugal fan 400 diffuses the air outward, the air diffused outward is air cooled by the auxiliary cooling medium 510. When the cooled air is in the box 100, it has a better heat dissipation effect on the inside of the digital power supply than air at room temperature, thereby improving the heat dissipation effect of the digital power supply and preventing damage to the digital power supply due to poor heat dissipation effect. This can further solve the technical problems existing in the prior art.

[0048] In one embodiment, reference Figure 3 The auxiliary cold carrier 510 includes a mounting plate 511 and a refrigeration component 512. The mounting plate 511 is fixed to the box body 100 by screw locking. The mounting plate 511 is used for mounting the centrifugal fan 400. The refrigeration component 512 is installed on the mounting plate 511 to cool the mounting plate 511. In this embodiment, the refrigeration component 512 can make the mounting plate 511 a cold plate, that is, the centrifugal fan 400 is installed on the cold plate. At this time, after the centrifugal fan 400 sucks in air, the air will contact the cold plate. At this time, the air is cooled by the cold plate, so that the auxiliary cold carrier 510 can cool the gas blown out by the centrifugal fan 400.

[0049] In other embodiments, the auxiliary cold carrier 510 may be a cold medium tube, wherein a cold medium flows through the cold medium tube. Under the action of the cold medium, the temperature of the surface of the cold medium tube is lowered. When the centrifugal fan 400 is installed in the cold medium tube, after the centrifugal fan 400 draws in air, the air will contact the surface of the cold medium tube. At this time, the cold medium tube will cool the air, so that the auxiliary cold carrier 510 can cool the gas blown out by the centrifugal fan 400.

[0050] In one embodiment, reference Figure 3 The cooling element 512 is configured as a cooling fin, which can reduce the space occupied by the cooling element 512, thereby effectively reducing the size of the digital power supply, making the digital power supply structure more compact and small. The cooling fin is installed on the side of the mounting plate 511 away from the centrifugal fan 400.

[0051] In one embodiment, reference Figure 5 There are multiple cooling fins, and the multiple cooling fins are all installed on the mounting plate 511 and installed in parallel in the circuit. In this embodiment, the purpose of setting up multiple cooling fins is to make the temperature of the mounting plate 511 lower so that the air in contact with it can be cooled down quickly. At the same time, multiple cooling fins are installed in parallel in the circuit. When one of the cooling fins is damaged, the remaining cooling fins can be used normally, thereby improving the use effect of this application.

[0052] In one embodiment, reference Figure 3 The digital power supply also includes a column 600 and a first heat dissipation hole 110. The column 600 is fixed to the box body 100, and the mounting plate 511 is fixed to the column 600 by screw locking. An installation space 130 is formed between the mounting plate 511 and the box body 100. The first heat dissipation hole 110 is opened in the box body 100 and is arranged corresponding to the installation space 130; the refrigeration component 512 is installed in the installation space 130, which can improve the heat dissipation effect of the side of the refrigeration plate away from the mounting plate 511, and facilitate the heat dissipation of the refrigeration plate. The refrigeration plate is arranged close to the first heat dissipation hole 110, and its main purpose is to improve the heat dissipation effect of the refrigeration plate.

[0053] In one embodiment, reference Figure 3 The cooling fin is provided with a heat dissipation fin 700 on the side facing away from the mounting plate 511. The heat dissipation fin 700 can further improve the heat dissipation effect of the cooling fin. Since the cooling fin is arranged close to the first heat dissipation hole 110, the heat dissipation fin 700 is also arranged close to the first heat dissipation hole 110, which can enable the heat dissipation fin 700 to contact the external air faster, so that the heat dissipation effect of the heat dissipation fin 700 is better, thereby making the heat dissipation effect of the cooling fin better.

[0054] In one embodiment, reference Figure 5 To further enhance the cooling effect of mounting plate 511, mounting plate 511 can employ the following structure: the interior of mounting plate 511 is hollow and filled with a refrigerant liquid. In this embodiment, the refrigerant liquid can be water, coolant, or the like. When a cooling fin is installed on mounting plate 511, the cooling fin cools mounting plate 511. Simultaneously with the cooling of mounting plate 511, the refrigerant liquid also cools the mounting plate 511. Furthermore, the cooling liquid reduces the cooling efficiency of mounting plate 511. In this embodiment, a tube 540 is mounted on mounting plate 511, through which the refrigerant liquid can be injected into the interior of mounting plate 511.

[0055] In one embodiment, the mounting plate 511 is made of a heat-conducting material with a thermal conductivity of at least 150 W / (m·K), so that the mounting plate 511 has a better cooling effect and facilitates air cooling.

[0056] In one embodiment, reference Figure 5 , the mounting plate 511 is configured as a bowl-shaped structure, and the centrifugal fan 400 is installed in the bowl-shaped structure. In this embodiment, when the mounting plate 511 is configured as a bowl-shaped structure, a cold space can be formed inside the mounting plate 511. At this time, when the centrifugal fan 400 draws air in, it can draw the air into the cold space. Since the temperature in the cold space is relatively low, the air can be quickly cooled down after entering the cold space, thereby accelerating the heat dissipation effect of the digital power supply. At the same time, in this embodiment, the outer side of the bowl-shaped structure can be configured as a hollow structure, so as to facilitate the discharge of air from the cold space to the outside. At the same time, it is configured as a hollow structure. When the air passes through the hollow structure, its hollow part can also absorb heat in the air, further cooling the air. In this embodiment, in order to facilitate the connection between the mounting plate 511 with a bowl-shaped structure and the box body 100, a mounting pin 520 is fixed to the outside of the mounting plate 511.

[0057] In one embodiment, reference Figure 2 、 Figure 4The auxiliary cooling assembly 500 further includes a temperature sensor 530 electrically connected to the auxiliary cooling carrier 510. The temperature sensor 530 is primarily used to control the power of the refrigeration element 512, specifically the cooling power of the cooling fins. This increases the cooling efficiency of the cooling fins by increasing the cooling fin power, thereby enabling the mounting plate 511 to be more quickly converted into a cold plate. In this embodiment, the temperature sensor 530 is electrically connected to the cooling fins to detect the temperature within the housing 100. When the temperature within the housing 100 is detected to be gradually increasing, the cooling fin power is increased to lower the temperature of the mounting plate 511. Furthermore, when the mounting plate 511 is bowl-shaped and hollow, the air entering the centrifugal fan 400 and then being blown out of the centrifugal fan 400 can be cooled more quickly. In this embodiment, methods for regulating the cooling fin power include, but are not limited to, pulse width modulation control, voltage regulation, and the use of variable resistors or DC resistors. In this embodiment, second heat dissipation holes 120 are provided in the housing 100. When the temperature sensor 530 detects a low temperature within the housing 100, the auxiliary refrigerant 510 is not required to operate, and only the centrifugal fan 400 is required to operate. This reduces power consumption and conserves energy. Furthermore, the first and second heat dissipation holes 110, 120 improve air flow within the housing 100.

[0058] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
