[0002] Safety isolation power module power supply is a power module that is usually used to provide electrical isolation and protection functions to ensure a high degree of safety between electrical equipment. These modules usually include isolation circuits between input and output, which can effectively isolate the electrical connection between the input and output ends and prevent damage or dangerous situations caused by electrical interference.

A power module body 8 is opened inside the protective inner cavity 101, and a heat sink 9 is fixedly connected to the side surface of the power module body 8 away from the output socket 3. An inspection door 10 is movably connected to the side surface of the protective shell 1 away from the opening of the mounting plate 5. The inspection door 10 is used to facilitate the inspection and maintenance of the power module.

[0025] Reference Figure 3 As shown, heat dissipation holes 102 are provided on the top of the protective shell 1 at the position where the exhaust fan 2 is provided, output holes 103 are provided on the surface of the protective shell 1 at the position where the output socket 3 is provided, input holes 104 are provided on the surface of the protective shell 1 at the position where the input socket 4 is provided, and air intake holes 105 are provided on one side of the surface of the protective shell 1 at the position where the mounting plate 5 is provided. The exhaust fan 2 is used to discharge the heat generated by the operation of the power module to prevent high temperature from affecting the normal use of the power module.

[0026] Reference Figure 3 As shown, a rectangular slide groove 501 is provided at the position of the mounting plate 5 movably connected to the moisture-proof box 6 , and the rectangular slide groove 501 is conducive to the rapid installation of the moisture-proof box 6 .

[0027] Reference Figure 4 As shown, a heat insulating pad 1001 is fixedly connected to the surface of one side of the inspection door 10 close to the protective shell 1, and mounting bolts 1002 are movably connected to the four corners of the surface of the inspection door 10. The inspection door 10 is fixedly connected to one side of the protective shell 1 by the mounting bolts 1002. The mounting bolts 1002 facilitate the installation and fixation of the inspection door 10.

[0028] Reference Figure 5 As shown, a moisture-proof inner cavity 601 is opened inside the moisture-proof box 6, neatly arranged circular through holes 602 are opened on the surface of the moisture-proof box 6, rectangular slide rails 605 are opened on both sides of the surface of the moisture-proof box 6 near the bottom, and neatly arranged solid desiccants 11 are opened inside the moisture-proof inner cavity 601 of the moisture-proof box 6. The moisture-proof box 6 is conducive to adsorbing moisture in the air and blocking impurities and dust in the air, thereby preventing the components inside the power module from being damaged and increasing the maintenance cost.

[0029] The working principle of the utility model is as follows: first, during use, when the external temperature is high, the heat insulation plate 7 opened on the inner wall of the protective shell 1 isolates the external high temperature to prevent affecting the normal operation of the power module body 8, and absorbs the heat generated by the operation of the power module body 8 itself through the heat sink 9 on the surface of the power module body 8, and then the exhaust fan 2 in the heat dissipation hole 102 stuck in the protective shell 1 discharges the temperature absorbed by the heat sink 9, so that the temperature of the power module body 8 during operation is stabilized, and when the exhaust fan 2 discharges the hot air in the protective inner cavity 101, a negative pressure state is formed inside the protective inner cavity 101, and the air inlet hole 105 opened on one side of the protective shell 1 draws external air into the protective inner cavity 101 to reduce the temperature of the power module body 8 Temperature, and then when there is more moisture or more dust particles in the external air, the circular through holes 602 on the surface of the moisture-proof box 6 will block the dust, and the solid desiccant 11 inside the moisture-proof inner cavity 601 will absorb the moisture in the air, so that the air entering the protective inner cavity 101 remains dry, avoiding the power module body 8 from being damaged due to dust or moisture, thereby generating additional maintenance costs, and then when inputting voltage or outputting voltage, just insert the corresponding connecting wire into the output socket 3 or the input socket 4. When the power module body 8 needs to be inspected, the mounting bolts 1002 on the surface of the rotating inspection door 10 will move the inspection door 10 away from the protective shell 1, and then the power module body 8 in the protective inner cavity 101 can be taken out for maintenance.
