Description
Technical Field
[0001] The present application relates to the field of electric power equipment, and in particular to a heat dissipation structure of a distribution box. Background Art
[0002] The distribution box is a systematic power distribution device with an electrical system installed inside, including components such as voltage maintainers, electronic protection devices, relays, cables and connectors. The function of the distribution box is to input electrical energy into areas that do not interfere with each other, avoid power overload, ensure that electrical equipment receives stable power supply, and ensure the safety of electricity.
[0003] Distribution boxes are widely used in industries such as industry, construction, and medical treatment. They can be divided into low-voltage distribution boxes and high-voltage distribution boxes. The electrical components installed inside the distribution boxes will generate heat during operation. If the heat is not dissipated in time, the equipment will overheat and cause a series of adverse consequences, such as failure, damage, and even fire.
[0004] At present, most of the heat dissipation is done by air cooling, but as more and more electronic components are installed in the distribution box, the air cooling cannot achieve the expected effect. Therefore, there is an urgent need for a device that can quickly dissipate heat for the internal components of the distribution box. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of the present application is to provide a heat dissipation structure for a distribution box to solve the problem of rapid heat dissipation inside the distribution box in the above-mentioned background technology.
[0006] The above technical problems solved by the present application are achieved through the following technical solutions:
[0007] A heat dissipation structure of a distribution box comprises a distribution box and a heat dissipation structure, wherein the heat dissipation structure comprises a cooling pipe, a cooling box, a first hose, a second hose, a water pump and a cooling fan, wherein the cooling pipe is installed inside the distribution box, and both ends of the cooling pipe extend to the outside of the distribution box through through holes on the side wall of the distribution box, one end of the cooling pipe is connected to one end of the first hose, and the other end of the first hose is connected to the water pump, and the water pump is installed at the water outlet of the cooling box, and the water suction port of the water pump is connected to a third hose, and the third hose extends to the bottom of the cooling box, the other end of the cooling pipe is connected to one end of the second hose, and the other end of the second hose is connected to the return water port of the cooling water tank, and a cooling fan is installed on one side of the cooling box.
[0008] By adopting the above technical solution, after the distribution box is put into use, the electrical components in the distribution box start to work and generate heat, and then the water pump is started, the water pump will draw the cooling medium in the cooling box into the cooling pipe, and the cooling pipe placed in the distribution box will absorb the heat in the distribution box. The cooling medium that absorbs the heat flows into the cooling water tank for cooling and is then transported to the cooling pipe by the water pump. Driven by the water pump, the cooling medium will continuously circulate between the cooling box and the cooling pipe to achieve the purpose of cooling the inside of the distribution box.
[0009] According to a further optimization scheme, the cooling tube is an aluminum tube, and a water-absorbing sponge is provided on the outer surface of the cooling tube.
[0010] By adopting the above technical solution, the aluminum cooling pipe can have good thermal conductivity and can quickly absorb the heat in the distribution box.
[0011] While the cooling pipe absorbs the heat inside the distribution box, water droplets may form on the outer surface of the cooling pipe due to the different temperatures inside and outside the cooling pipe. The absorbent sponge installed outside the cooling pipe will absorb the water droplets formed on the surface of the cooling pipe to prevent the water droplets from flowing into the distribution box and increasing the humidity inside the distribution box, thereby causing the electronic components inside the distribution box to become damp and affecting their service life.
[0012] A further optimization scheme is that the cooling box is grid-shaped, and a plurality of baffles are arranged between the water channels of the cooling box. The bottom end of the baffle is vertically fixedly connected to the lower wall of the water channel, and the other end and the upper wall of the water channel leave space for the cooling medium to flow.
[0013] By adopting the above technical solution, the cooling box is configured to have a multi-layer grid shape, so that the cooling pipes in the cooling box will be correspondingly longer, and the cooling medium will flow through the cooling box for a longer time, so that the cooling medium can be fully cooled down, and the blocking plates arranged at relative positions of adjacent water channels can slow down the flow of the cooling medium to the bottom of the cooling box, thereby increasing the cooling effect of the cooling medium.
[0014] According to a further optimization scheme, a filling port is provided at the upper end of the cooling box, and a filling port cover is provided on the filling port.
[0015] By adopting the above technical solution, the cooling medium will be consumed in actual work, and the cooling medium can be conveniently replenished through the filling port.
[0016] According to a further optimization scheme, an exhaust fan is installed on the side wall of the distribution box close to the cooling pipe, the exhaust fan is fixedly connected to the side wall, and an exhaust hole is opened on the side wall.
[0017] By adopting the above technical solution, the water-absorbing sponge on the cooling pipe can prevent the water droplets from flowing into the distribution box after absorbing the water droplets, or the moisture in the distribution box is too heavy during natural evaporation, which may damage the electronic components in the distribution box. Exhaust holes can be provided on the side wall and an exhaust fan can be installed. The air flow can be accelerated to accelerate the evaporation of water in the absorption sponge and discharge it through the exhaust fan, which can prevent the moisture in the absorption sponge from flowing into the distribution box, or the evaporated moisture from affecting the electronic components in the distribution box.
[0018] According to a further optimization scheme, the distribution box is provided with an air inlet at the lower part of the side wall opposite to the side wall where the exhaust hole is provided.
[0019] By adopting the above technical solution and setting an air inlet on the distribution box, the air flow in the distribution box can be increased, and air cooling can assist the heat dissipation structure to cool the distribution box.
[0020] As a further optimization solution, a dust screen is installed on the inner side of the air inlet.
[0021] By adopting the above technical solution, the dustproof net can prevent dust from entering the distribution box and affecting the working stability of the electronic components in the distribution box.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. By installing aluminum cooling pipes inside the distribution box, setting up a multi-grid cooling box and a cooling fan outside the distribution box, and setting a baffle plate inside the cooling box, the aluminum cooling pipes can effectively absorb the heat in the distribution box, and the cooling medium flows in the cooling box for a long enough time, which can effectively improve the purpose of cooling the distribution box.
[0024] 2. By installing a water-absorbing sponge on the outer surface of the cooling pipe, opening ventilation holes on the side wall and setting an exhaust fan, the moisture in the water-absorbing sponge can be quickly evaporated and discharged out of the distribution box, preventing excessive moisture in the distribution box from affecting the stability of the electronic components in the distribution box.
[0025] 3. By setting up air inlets and cooperating with exhaust fans, the air flow in the distribution box can be accelerated, and the auxiliary cooling structure can cool down the electronic components in the distribution box. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0034] Example, see Figure 1 , Figure 2 , Figure 3 and Figure 4 A heat dissipation structure of a distribution box includes a distribution box 1 and a cooling pipe 2 installed inside the distribution box 1. A through hole is opened on the side wall of the distribution box 1 to facilitate the installation of the cooling pipe. Both ends of the cooling pipe 2 extend to the outside of the distribution box 1 through the through holes on the distribution box 1. One end of the cooling pipe 2 is connected to one end of a first hose 4, and the other end of the first hose 4 is connected to a water pump 6. The water pump 6 is installed at the water outlet of the cooling box 3. The water suction port of the water pump 6 is connected to one end of a third hose 8, and the other end of the third hose 8 extends to the bottom of the cooling box 3. The water pump 6 extracts the cooling medium at the bottom of the cooling box 3 through the third hose 8 and then transports the cooling medium to the cooling pipe 2. The other end of the cooling pipe 2 is connected to one end of a second hose 5, and the other end of the second hose 5 is connected to the return water port of the cooling box 3. In order to further cool the cooling medium, a cooling fan 7 is installed on one side of the cooling water tank.
[0035] In this embodiment, the cooling box 3 is installed on the side wall of the distribution box 1. In reality, the installation position of the cooling box 3 can be determined according to specific circumstances.
[0036] A water-absorbing sponge 9 is installed on the outer surface of the cooling tube 2 to prevent water droplets generated by the cooling tube 2 during heat exchange from gathering together and flowing into the distribution box 1, and making the air inside the distribution box 1 humid after evaporation, thereby affecting the working stability of the electronic components in the distribution box 1.
[0037] Furthermore, an exhaust fan 14 is installed on the side wall of the distribution box 1 near the cooling pipe 2. The exhaust fan 14 is fixedly connected to the side wall of the distribution box 1, and an exhaust hole 15 is opened on the side wall of the distribution box 1 parallel to the exhaust fan 14. In this way, the exhaust fan 14 can accelerate the air flow in the distribution box 1, accelerate the evaporation of water in the absorbent sponge 9, and the exhaust fan 14 can remove the evaporated moisture from the distribution box 1 in time.
[0038] Furthermore, an air inlet 16 is opened at a lower position on the side wall of the other side of the distribution box 1, which can increase the air intake of the distribution box 1, and can assist the heat dissipation structure to cool down the electronic components in the distribution box 1, thereby further improving the heat dissipation effect of the distribution box 1.
[0039] In order to allow the cooling medium to fully dissipate heat after absorbing heat, refer to Figure 4 , the direction of the arrow is the direction of the cooling medium flow, the cooling box 3 installed outside the distribution box 1 adopts a multi-grid shape, so that the cooling box 3 is divided into a curved S-shaped waterway from top to bottom, and a blocking plate 10 is arranged at the opposite ends of adjacent waterways, so that the cooling medium flowing through the cooling box 3 can be prolonged, and the cooling medium can be fully dissipated, and a cooling fan 7 is installed at one end of the cooling box 3 to further dissipate the heat of the cooling medium.
[0040] The cooling medium will be consumed in actual use. A filling port 12 is installed on the cooling box 3 to facilitate the replenishment of the cooling medium, and a filling port 12 cover is threadedly connected to the filling port 12.
[0041] In order to prevent excessive dust from entering the distribution box 1 and affecting the working stability of the electronic components in the distribution box 1 , a dustproof net 17 is installed inside the air inlet 16 .
[0042] In the specific implementation process, after the distribution box 1 is put into use and the electrical components in the distribution box 1 are working, the water pump 6, the cooling fan 7 and the exhaust fan 14 are started, and the third water pipe connected to the water suction port of the water pump 6 will extract the cooling medium from the bottom of the cooling box 3. The cooling medium will pass through the water pump 6 and then through the first hose 4 and then flow into the cooling pipe 2. The cooling medium that absorbs heat will flow into the cooling box 3 after passing through the second hose 5 driven by the water pump 6. While the cooling medium flows in the curved S-shaped water channel in the cooling box 3, the cooling fan 7 cools the cooling medium. The cooled cooling medium flows to the bottom layer of the cooling box 3, and then flows into the cooling pipe 2 after being sucked by the water pump 6. In this way, an uninterrupted cycle is performed to cool and dissipate heat in the distribution box 1, and the exhaust fan 14 will also work continuously, which can assist the heat dissipation structure in dissipating heat from the distribution box 1 while accelerating the evaporation of water in the water-absorbing sponge 9. This prevents the electrical components in the distribution box 1 from being damp and affecting the stability of the equipment.
[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
