[0002] Switching power supplies take AC power (such as mains power) or DC power as input and output a controllable DC power supply. They are widely used in communication equipment, industrial control, home appliances, new energy, and other fields. However, existing switching power supplies have the following drawbacks: 1. The circuit boards inside the power supply are large, resulting in a relatively large overall size; 2. There are many control lines and power lines inside the power supply, making the wiring complex and messy, which makes installation and maintenance very troublesome, time-consuming, and labor-intensive; 3. The integration is not high, the front-end AC / DC and DC / DC circuits are arranged in a disorderly manner, and the electrical components cannot be modularly combined.

[0003] Therefore, designing a water-cooled power supply that has good heat dissipation, relatively small size, neat and orderly wiring, high integration, and is easy to maintain is a technical problem that the industry urgently needs to solve. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0018] Please see Figures 1-4 The present invention discloses a water-cooled power supply with a simple structure, including a chassis. In a preferred embodiment, the chassis includes a frame 7a, a power end cover 7b installed at the power connection end, a water pipe end cover 7c installed at the water pipe connection end, side cover plates 7d installed on both sides, and a top cover plate 7e installed on the top, wherein the top cover plate 7e is provided with an equipment nameplate 11.

[0019] The water-cooled power supply includes an AC / DC module, a DC / DC module, and a first heat sink 3a and a second heat sink 3b mounted parallel to each other inside the chassis. The AC / DC module and the DC / DC module are respectively mounted on the sides of the first heat sink 3a and the second heat sink 3b for heat dissipation. In a preferred embodiment, the first heat sink 3a and the second heat sink 3b are water-cooled.

[0020] Combination Figure 1 and Figure 2 In a preferred embodiment, the chassis is a cuboid, with one end serving as a power connection terminal and the other end as a water pipe connection terminal. The power connection terminal is equipped with an AC interface 4a and a DC interface 4b. The AC interface 4a connects to the AC / DC module, and the DC interface 4b is connected to the DC / DC module via a series connection with the heat sink. The water pipe connection terminal has a first water pipe interface 3a1 connecting to the first heat sink 3a and a second water pipe interface 3b1 connecting to the second heat sink 3b. (See also...) Figure 1 or Figure 2 The power connection terminal is also equipped with several data interfaces 12 for connecting AC / DC modules and DC / DC modules to facilitate data communication and control.

[0021] By placing the power connection and water pipe connection at opposite ends of the power source, the live and water interfaces can be separated at opposite ends of the equipment, effectively reducing the risk of leakage and facilitating installation and maintenance. In a preferred embodiment, the AC interface 4a for connecting to the external AC power grid uses a plug-in connector, and the DC interface 4b for connecting to the DC load includes a positive copper busbar (located at...). Figure 1 (lower part) and a negative electrode copper busbar (located in) Figure 1 The upper part of the first water pipe interface 3a1 actually includes an inlet interface and an outlet interface, and the second water pipe interface 3b1 also includes an inlet interface and an outlet interface. It should be noted that, in a preferred embodiment, the heat sink is used as a conductive copper busbar. (See reference...) Figure 5 The copper busbar at the positive terminal of DC interface 4b is connected in series with the first heat sink 3a, then in series with the inductor 8, and finally connected to the DC / DC module. The copper busbar at the negative terminal of DC interface 4b is connected in series with the second heat sink 3b, then in series with the inductor 8, and finally connected to the DC / DC module. This design can save on the amount of copper busbars used, reduce the size of the power supply, and save on costs.

[0022] See Figure 5 The AC / DC module is shown in a three-dimensional view. Figure 6 The three-dimensional view of the DC / DC module shown indicates that the first heat sink 3a and the second heat sink 3b adopt a long strip-shaped plate structure with a rectangular cross-section. The sides of the first heat sink 3a and the second heat sink 3b are parallel to the sides of the chassis. The AC / DC module is mounted on one side of the first heat sink 3a and the second heat sink 3b, and the DC / DC module is mounted on the other side of the first heat sink 3a and the second heat sink 3b. A first water pipe interface 3a1 is provided at one end of the first heat sink 3a, and a second water pipe interface 3b1 is provided at one end of the second heat sink 3b. This design allows for a neat and standardized arrangement of the modules, which is beneficial for optimizing the layout of the PCBA and copper busbars, improving integration, reducing size, and making installation and maintenance more convenient.

[0023] See Figure 5 and Figure 6 Since the electrolytic capacitor 5 is relatively large, installing it on both sides of the heat sink would inevitably increase the size of the power supply. Therefore, in a preferred embodiment, a mounting gap is left between the first heat sink 3a and the second heat sink 3b, and the electrolytic capacitor 5 from the DC / DC module is installed in the mounting gap.

[0024] See Figure 6To improve the heat dissipation effect of inductor 8, the first heat sink 3a has an inductor 8 from the DC / DC module mounted on its edge away from the mounting gap; the second heat sink 3b has an inductor 8 from the DC / DC module mounted on its edge away from the mounting gap.

[0025] See Figure 5 For modular design, the AC / DC module is divided into a filter module 1a and a conversion module 1b, wherein the filter module 1a is installed on one side of the first heat sink 3a, and the conversion module 1b is installed on one side of the second heat sink 3b.

[0026] See Figure 6 When the load is a DC pulse type load (such as a three-phase AC motor, a DC motor group, a multi-phase stepper motor, etc.), the DC / DC module includes three H-bridge output modules 2a, wherein the left bridge arm of the three H-bridge output modules 2a is installed on the other side of the first heat sink 3a, and the right bridge arm of the three H-bridge output modules 2a is installed on the other side of the second heat sink 3b; the input of each H-bridge output module 2a is electrically connected through a copper busbar 10.

[0027] See Figures 1 to 4 The chassis includes a frame 7a, a power supply end cover 7b installed at the power connection end, and a water pipe end cover 7c installed at the water pipe connection end. A power supply end insulating plate is installed on the inner side of the power supply end cover 7b, and a water pipe end insulating plate is installed on the inner side of the water pipe end cover 7c. The AC interface 4a and DC interface 4b extend from the window of the power supply end cover 7b, and the first water pipe interface 3a1 and the second water pipe interface 3b1 extend from the window of the water pipe end cover 7c. To improve the strength of the equipment, each cover is made of iron plate. To improve insulation, a power supply end insulating plate is installed on the inner side of the power supply end cover 7b, and a water pipe end insulating plate is installed on the inner side of the water pipe end cover 7c. The live interfaces extend through the insulating plates and then protrude from the pre-reserved windows in the cover plates.

[0028] See Figure 1 Figure 2 To facilitate the use of portable power devices, handles 9 are provided on the frame 7a, the power supply end cover 7b, or the water pipe end cover 7c.

[0029] The above embodiments are merely illustrative and not intended to be limiting. Any equivalent modifications or alterations made without departing from the spirit and scope of this application should be included within the scope of the claims of this application.
