[0022] As Figures 1-5 shown, a sheet metal part of a distribution box provided in this embodiment includes a distribution box 1, a cold row 2 is fixedly installed inside the distribution box 1, a circulation box 3 is fixedly installed on the top of the distribution box 1, a water inlet pipe 4 is fixedly connected to the top of the cold row 2, one end of the water inlet pipe 4 penetrates through the outer surface of the distribution box 1 and is connected to a water pump 5, one side of the water pump 5 is connected to the circulation box 3, a water outlet pipe 6 is fixedly connected to one side of the circulation box 3, one end of the water outlet pipe 6 is connected to the bottom of the cold row 2, and a plurality of heat conduction plates 7 are installed inside the distribution box 1.

[0023] In this embodiment, starting the water pump 5 can extract the coolant in the circulation box 3 and continuously transport it to the inside of the cold row 2 through the water inlet pipe 4. The coolant can circulate inside the cold row 2, and the heat generated by the operation of the electrical devices is continuously transferred to the cold row 2 through the heat conduction plates 7. The cold row 2 absorbs and takes away this part of the heat through the coolant. As the heat is continuously transferred to the cold row 2, the temperature of the coolant inside it will rise. At this time, the coolant is transported back to the circulation box 3 through the water outlet pipe 6 for cooling, so as to achieve continuous cyclic heat absorption and continuously provide efficient heat dissipation support, prevent the situation that the internal electrical devices of the sheet metal part of the distribution box are damaged due to poor heat dissipation, and effectively improve the service life of the electronic equipment.

[0024] As Figures 2-5 shown, one side of the heat conduction plate 7 is attached to one side of the cold row 2, two slide rails 8 are symmetrically installed on the inner wall of the distribution box 1, and the heat conduction plate 7 is slidably installed between the two slide rails 8; a plurality of installation holes 9 are formed in the heat conduction plate 7, a plurality of bolts 10 are threadedly engaged with the heat conduction plate 7, and a plurality of threaded holes 11 adapted to the bolts 10 are symmetrically formed on the slide rails 8; engaging chutes 19 are formed on both the front and rear sides of the slide rails 8, and engaging sliders 20 adapted to the engaging chutes 19 are provided on the heat conduction plate 7.

[0025] In this embodiment, the provision of the installation holes 9 facilitates the installation of electronic devices / equipment on the heat conduction plate 7. Rotate the bolt 10 to disengage it from the inside of the threaded hole 11 and no longer limit and fix the heat conduction plate 7; through the provision of the slide rails 8, the heat conduction plate 7 can move up and down on the slide rails 8 to a suitable position to be flexibly adjusted according to the actual size and installation requirements of the electrical equipment, ensuring that the electrical components can be installed in a suitable position; when adjusted to a suitable position, rotate the bolt 10 to move it into the threaded hole 11 to limit and fix the heat conduction plate 7 to prevent it from shaking; the provision of the engaging chutes 19 and the engaging chutes 19 can reduce the resistance when the heat conduction plate 7 slides on the slide rails 8, enabling it to move more smoothly.

[0026] As Figures 1-3 shown, a wind collecting hood 12 is fixedly connected to the bottom of the distribution box 1. A support frame 13 is fixedly installed inside the wind collecting hood 12. A spiral blade 14 is rotatably installed on the top of the support frame 13. A motor 15 connected to one side of the spiral blade 14 is fixedly installed at the bottom of the support frame 13. A thread 16 is provided on the surface of the wind collecting hood 12. A sleeve 23 is threadedly connected to the bottom of the wind collecting hood 12. A filter screen 24 is fixedly installed at the bottom of the sleeve 23.

[0027] In this embodiment, when the motor 15 is started to drive the spiral blade 14 to rotate, the external air can be continuously conveyed into the distribution box 1 through the spiral blade 14 to blow and dissipate heat from the electrical components in the distribution box 1, further improving the heat dissipation effect; the filter screen 24 can filter out impurities in the air to prevent dust particles from entering the distribution box 1 and adhering to the electrical components, causing poor contact of the electrical components; when the dust on the filter screen 24 needs to be cleaned, the sleeve 23 is rotated and moves downward continuously under the action of the thread 16 until it is separated from the wind collecting hood 12, facilitating the removal of the filter screen 24 for cleaning to prevent the filter screen 24 from being blocked by dust, resulting in the obstruction of air flow and affecting the heat dissipation effect.

[0028] As Figures 1-3 shown, a protection door 17 is movably installed on the front end face of the distribution box 1. An observation window 18 is provided on the surface of the protection door 17. A plurality of support legs 21 are fixedly installed at the bottom of the distribution box 1. A rubber protection sleeve 22 is fixedly installed on the support legs 21.

[0029] In this embodiment, the protection door 17 can prevent external substances from entering the distribution box 1 to protect the electrical components; the setting of the observation window 18 facilitates observing the situation inside the distribution box 1 without opening the protection door 17, eliminating the need to frequently open and close the protection door 17; the rubber protection sleeve 22 can protect the support legs 21 to prevent the support legs 21 from being corroded in a humid environment.

[0030] As Figures 1-5 shown, the principle of a sheet metal part of a distribution box provided in this embodiment is as follows: When the water pump 5 is started, the coolant in the circulation tank 3 can be pumped out and continuously conveyed into the cold radiator 2 through the water inlet pipe 4. The coolant can circulate inside the cold radiator 2, and the heat generated by the electrical equipment is continuously transferred to the cold radiator 2 through the heat conduction plate 7. The cold radiator 2 absorbs and takes away this part of the heat through the coolant; as the heat is continuously transferred to the cold radiator 2, the temperature of the coolant inside it will rise after absorbing the heat. At this time, the coolant can be conveyed back to the circulation tank 3 through the water outlet pipe 6 for cooling to achieve continuous cyclic heat absorption and continuously provide efficient heat dissipation support, preventing the internal electrical devices of the sheet metal part of the distribution box from being damaged due to poor heat dissipation and effectively extending the service life of the electronic equipment.
