[0025] The exhaust pipe 8 is fixedly sleeved inside the electric heating coil 10, and the material of the exhaust pipe 8 is stainless steel. By setting the exhaust pipe 8, when dehumidifying the power cabinet 2, the control seat 9 and the No. 1 air pump 7 are started, so that the control seat 9 can drive the electric heating coil 10 to start, and then heat the exhaust pipe 8, that is, heat the air inside the exhaust pipe 8.

[0032] The working principle of a cooling device for a high-power shore power supply provided by the utility model is as follows:

[0033] Step 1: First, when dehumidifying the power cabinet 2, start the control seat 9 and the No. 1 air pump 7, so that the control seat 9 can drive the electric heating coil 10 to start, and then heat the exhaust pipe 8, that is, heat the air inside the exhaust pipe 8.

When the heat dissipation inside the chassis 3 is being carried out, the filter cover 13 can filter the air entering the inside of the chassis 3, so that the dust inside the air can be blocked to the outside of the chassis 3, thereby improving the cleaning effect inside the chassis 3;

[0034] Step 2: When installing and fixing the power cabinet 2, rotate the bolt 142 so that the bolt 142 can fix the base plate 1 on the ground through the support frame 141, so that the support frame 141 can fix and support the power cabinet 2 through the base plate 1, thereby avoiding the problem of accelerated corrosion of the power cabinet 2 when the power cabinet 2 is directly in contact with the ground. When the shore power supply is used outdoors, multiple baffles 152 can block the exhaust port 151, so as to avoid the problem that rainwater outside the power cabinet 2 drips into the exhaust port 151 and flows into the power cabinet 2, causing moisture inside the power cabinet 2, thereby improving the waterproof effect inside the power cabinet 2. When the shore power supply is used, the sound insulation board 16 can block the noise inside the power cabinet 2, so as to avoid the problem that the internal components of the power cabinet 2 generate loud noise when working, causing noise pollution in the power cabinet 2, thereby improving the sound insulation effect when the shore power supply is working.

At this time, the No. 1 air pump 7 can transport the air with higher temperature to the inside of the power cabinet 2, so that the moisture inside the power cabinet 2 can be evaporated by heat and then discharged to the outside of the power cabinet 2, thereby achieving the dehumidification effect inside the power cabinet 2, thereby avoiding the more cumbersome problem of manual dehumidification of the power cabinet 2, thereby improving the convenience of using the power supply (note the number here).
