Technical Field

[0001] This utility model relates to the field of computer technology, specifically to a waterproof computer power supply. Background Technology

[0002] Computer power supplies typically have cable routing holes on the power supply box to allow the output lines of electrical components inside the power supply box to extend to the outside of the computer power supply and connect to graphics cards and other components inside the chassis. However, the cable routing holes on existing computer power supplies have poor sealing performance and are not waterproof, allowing water to easily enter the power supply box through the cable routing holes and cause short circuits.

[0003] Therefore, it is necessary to propose a waterproof computer power supply to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a waterproof computer power supply to solve the problem mentioned in the background art that the sealing performance of the wiring hole on the existing computer power supply is poor and it does not have a waterproof effect, so that water can easily enter the power supply box from the wiring hole and cause short circuit.

[0005] Technical Solution: To achieve the above objectives, this utility model provides the following technical solution: A waterproof computer power supply, comprising a power supply box and a power interface embedded in the power supply box. The power supply box contains a heat dissipation mechanism and electrical components that convert AC power to DC power. Both the power interface and the heat dissipation mechanism are electrically connected to the electrical components. The heat dissipation mechanism includes a thermoelectric cooler and two heat sinks. The thermoelectric cooler is embedded in the power supply box, with its hot and cold ends located on the inner and outer sides of the power supply box, respectively. The two heat sinks are respectively attached to both ends of the thermoelectric cooler. The device is fixedly connected to the power supply box, and a water-absorbing filter screen is provided on the input end of the radiator fan inside the power supply box. A wire hole is opened on one side of the power supply box, and a connecting tube sealed at both ends is installed in the wire hole. A silicone tube sealed at both ends is installed inside the connecting tube. Multiple through holes are evenly opened on the inner end face of the connecting tube. The other end of the through holes passes through the silicone tube and the outer end face of the connecting tube in sequence. A silicone tube is installed in the through hole inside the silicone tube. The two ends of the silicone tube are flush with the silicone tube. An air inlet pipe is connected to the silicone tube. One end of the air inlet pipe extends to the outside of the power supply box and is fixedly installed with an air valve.

[0006] Preferably, the top of the power supply box has an installation opening, and a sealing plate for sealing the installation opening is bolted to the top of the power supply box, with a sealing gasket between the sealing plate and the power supply box.

[0008] Preferably, the connecting pipe is welded inside the wire hole, and a waterproof rubber ring is provided inside the power interface.

[0009] Beneficial effects: Compared with the prior art, this utility model provides a waterproof computer power supply. This waterproof computer power supply has a unique structure and is easy to use.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1: This Example 1 provides a waterproof computer power supply, which is a direct improvement on existing computer power supplies. It has a unique structure. Please refer to [link / reference]. Figure 1-5As shown, the device includes a power supply box 1 and a power interface 2 embedded in the power supply box 1. The power supply box 1 is equipped with a heat dissipation mechanism and an electrical component that converts AC power to DC power. The power interface 2 and the heat dissipation mechanism are electrically connected to the electrical component. The electrical component can convert the AC power transmitted from the power interface 2 into DC power and transmit it to the heat dissipation mechanism. The top of the power supply box 1 has an installation opening. A sealing plate 11 for sealing the installation opening is bolted to the top of the power supply box 1. A sealing gasket is provided between the sealing plate 11 and the power supply box 1 to enhance the sealing performance of the power supply box 1 and prevent water from entering the power supply box 1.

[0018] The heat dissipation mechanism includes a thermoelectric cooler and two heat sinks 9. The thermoelectric cooler is embedded in the power supply box 1, with its hot and cold ends located on the inner and outer sides of the power supply box 1, respectively. The two heat sinks 9 are respectively attached to both ends of the thermoelectric cooler and fixedly connected to the power supply box 1. A water-absorbing filter 10 is provided on the input end of the fan of the heat sink 9 inside the power supply box 1. By setting heat sinks 9 at both ends of the thermoelectric cooler, the temperature of the hot end of the thermoelectric cooler can be reduced, thereby enhancing the cooling effect of the cold end of the thermoelectric cooler. On the other hand, the hot air inside the power supply box 1 can circulate through the heat sinks 9, thereby cooling the electrical components inside the power supply box 1. In addition, by setting a water-absorbing filter 10 on the input end of the fan of the heat sink 9 inside the power supply box 1, moisture in the air inside the power supply box 1 can be absorbed, thereby preventing water vapor in the air from condensing at the cold end of the thermoelectric cooler. There are various choices for the water-absorbing filter 10, such as an activated carbon filter.

[0019] A wire hole is provided on one side of the power supply box 1. A connecting tube 3 with both ends sealed is installed inside the wire hole. A silicone tube 4 with both ends sealed is installed inside the connecting tube 3. Multiple through holes are evenly provided on the inner end face of the connecting tube 3. The other end of the through holes passes through the silicone tube 4 and the outer end face of the connecting tube 3 in sequence. A silicone tube 5 is installed in the through hole inside the silicone tube 4. Both ends of the silicone tube 5 are flush with the silicone tube 4. An air inlet pipe 7 is connected to the silicone tube 4. One end of the air inlet pipe 7 extends to the outside of the power supply box 1 and is fixedly installed with a valve 8. A valve core is provided inside the valve 8. An air nozzle cap is fitted on the external thread of the valve 8. There are multiple ways to install the connecting tube 3. For example, a fixing plate 6 is fixedly installed on the outer end of the connecting tube 3. The fixing plate 6 is fixed to the power supply box 1 by bolts. A sealing gasket is provided between the fixing plate 6 and the power supply box 1.

[0020] When using this computer power supply, the output lines of multiple electrical components are first extended through silicone tubes 5 to the outside of the power supply box 1. Then, an air pump is used to inflate the silicone tube 4. When high-pressure gas is injected into the silicone tube 4, the outer wall of the silicone tube 4 will be in close contact with the inner wall of the connecting tube 3, and the inner wall of the silicone tube 5 will also be in contact with the cable under the action of high-pressure gas, thereby sealing the wire hole and preventing water from flowing into the power supply box 1. In addition, by using a semiconductor cooling chip to dissipate heat from the electrical components inside the power supply box 1, it is unnecessary to open heat dissipation holes on the power supply box 1, thus giving the computer power supply good waterproof performance.

[0021] Example 2: The difference between Example 2 and Example 1 is that the connecting pipe 3 is welded inside the wire hole, and the power interface 2 is equipped with a waterproof rubber ring, which greatly improves the waterproof performance of the power box 1.

[0022] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
