A heat dissipation device for an electrical equipment machine room

Abstract

The present invention discloses a heat dissipation device for an electrical equipment machine room, which includes a fixed shell, a refrigeration device and an electrical equipment main body. A first cavity and a second cavity are formed inside the fixed shell. The rotating ring will drive its pressing block to slide in its first cavity and second cavity through a sliding rod, and during the sliding process of the pressing block, it will also press the water injection bag in the first cavity, and the liquid in the water injection bag will be injected into its tube body through pressure and finally flow into the water injection bag in the second cavity, thus completing a cycle. At the same time, when the rotating rod rotates, it will also drive its connecting rod to rotate through a transmission belt, and force its fan blade to rotate through the rotation of the connecting rod. Thus, the wind generated by the rotation of the fan blade will dissipate heat from the electrical equipment main body through the tube body. And when the motor rotates in reverse to drive the fan blade to rotate in reverse, the heat dissipation device on the other side can also blow cold air into the electrical equipment main body through the fan blade.

The important role played by electricity in our life and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. The most crucial factor for electricity to operate and be transmitted normally in the machine room is electrical equipment.

[0003] The heat dissipation of existing electrical equipment in the machine room generally adopts the method of wind heat dissipation. There are many electrical equipment in the machine room and the equipment runs for a long time, resulting in an excessively high overall temperature in the machine room.

One end of the pipe body 4 is inserted into the first cavity 101, and the other end is inserted into the second cavity 102. The pipe body 4 is communicated with the water injection bags 7 in both the first cavity 101 and the second cavity 102, and the pipe body 4 is fixed to the fixed shell 1;

[0032] A rotating mechanism 2 is provided at the rear end of the fixed shell 1;

[0033] The rotating mechanism 2 includes a rotating ring 201, a tooth groove 202, and a limiting ring 203. The outer circumference of the rotating ring 201 is provided with a tooth groove 202, and a limiting ring 203 is fixed at the front end of the rotating ring 201. An annular groove is provided at the rear end of the fixed shell 1, and the limiting ring 203 is rotationally limited in the annular groove, so that the rotating ring 201 rotates on the fixed shell 1 through the cooperation of the limiting ring 203 and the annular groove.

[0034] A pressing block 3 is arranged in both the first cavity 101 and the second cavity 102.

[0035] A rotating rod 5 penetrates through the lower end of the fixed shell 1, and a gear 6 is fixed on the rotating rod 5. One end of the rotating rod 5 is rotatably connected to a motor 13, and the gear 6 meshes with the tooth groove 202.

[0036] A fan blade 10 is further arranged at the center inside the fixed shell 1 beside the pipe body 4.

[0037] A sliding rod 15 is fixed at the rear end of the pressing block 3, and the sliding rod 15 slides on the annular opening 103. The sliding rod 15 is fixedly connected to the rotating ring 201.
