Please refer to fig. 1-4, in the embodiment of the present invention, a heat dissipation system for use in an enclosed space, including fixing the dust removal box 2 in the enclosed space, the dust removal box 2 sucks the air outside the enclosed space, and discharges the air into the enclosed space to thereby play a cooling effect to the enclosed space. Usually, an air inlet pipe 1 is fixed at an air inlet of the dust removal box 2, the air inlet pipe 1 is communicated with the outside, and an air suction pump is additionally arranged in the air inlet pipe 1 to play a role in air suction. The dust removal box 2 is fixed outside the closed space, a pipeline is additionally arranged at an air outlet of the dust removal box 2, and the pipeline is communicated with the inside of the closed space, so that the heat dissipation function can be realized.

A cathode filter screen 3 and an anode filter barrel 4 are arranged in the dust removing box 2, the anode filter barrel 4 divides the inner cavity of the dust removing box 2 into a cavity to be removed with dust and a dust-free cavity, and the cathode filter screen 3 is fixed in the cavity to be removed with dust. The cathode filter 3 is preferably fixed at the air inlet of the dust box 2.

The bung of the anode filter barrel 4 is turned outside to form a flanging. The flanging is fixedly connected with the wall of the dust removal box 2, so that the flanging is suspended in the dust removal box 2.

After entering the dust removing box 2, the outside air firstly passes through the cathode filter screen 3. The cathode filter screen 3 forms hairiness by spinning conductive fibers, the hairiness is used as an emitter after being woven into a net, and cold-emitted electrons form electron mist. After the outside air passes through the electron fog generated by the cathode filter screen 3, dust in the air and electrons are adsorbed together and are negatively charged. The wall of the anode filter barrel 4 is an anode filter screen which is positively charged, and when the outside air is mixed with negatively charged dust and passes through the anode filter barrel 4, the dust is adsorbed on the anode filter screen. The outside air becomes dustless after passing through the anode filter screen, and is discharged into the closed space from the air outlet of the dust removal box 2, so that the temperature of the closed space is reduced.

In order to prevent the anode filter barrel 4 from being excessively dusty, a dust suction assembly 5 is usually arranged in the barrel to suck dust on the barrel wall. The dust suction assembly 5 is preferably a dust suction nozzle 54, and the dust suction nozzle 54 can be spirally lifted along with the bracket 51 by arranging the screw rod 52 in the anode filter barrel 4 along the axial direction of the barrel body, fixing the bracket 51 on the nut of the screw rod 52, and starting the screw rod 52 after the dust suction nozzle 54 is fixed on the bracket 51, so that dust adsorbed in the anode filter barrel 4 can be sucked completely.

The anode filter screen on the wall of the anode filter barrel 4 is of a double-layer structure, the inner layer of the anode filter screen is a metal power grid, the outer layer of the anode filter screen is a breathable filter screen, and the two layers of structures are tightly attached together. In order to improve the adsorption effect of the dust suction nozzle 54, an elastic member is arranged on the bracket 51 along the radial direction of the anode filter barrel 4, one end of the elastic member is fixed on the bracket 51, and the other end of the elastic member is connected and fixed with the dust suction nozzle 54. Under the elastic action of the elastic part, the dust suction nozzle 54 is always abutted against the anode filter screen, and after the negative pressure device is arranged in the dust suction nozzle 54, the maximum suction force can be ensured during dust suction. The resilient member is preferably a compression spring here. A dust exhaust pipe 6 is arranged in the dust box 2, a dust suction pipe 53 is arranged on the dust suction nozzle 54, and the dust suction pipe 53 is rotatably connected with the dust exhaust pipe 6. After the dust is sucked by the dust suction nozzle 54, the dust passes through the dust suction pipe 53 and the dust exhaust pipe 6 in order and is discharged to the outside of the closed space. In order to ensure the normal relative rotation between the dust suction pipe 53 and the dust exhaust pipe 6, a bearing bracket is usually fixed in the dust box 2, and a bearing is fixed on the bearing bracket, so that the dust suction pipe 53 and the dust exhaust pipe 6 are connected through the bearing, and the dust exhaust pipe 6 is ensured to be stationary and the dust suction pipe 53 rotates together with the dust suction nozzle 54 in the working process. The arrangement of the anode filter barrel 4 is only a preferred embodiment, and the anode filter screen with any shape is arranged in the dust removing box 2 for the external air to pass through, and the dust suction assembly 5 with any working mode is arranged for performing dust suction treatment on the anode filter screen. For example, an anode filter screen is fixed at the air outlet of the dust removing box 2, and a strip-shaped dust collector which rotates around the center of the screen surface is arranged on the anode filter screen, so that the function of filtering dust can be realized.

The space between the anode filter barrel 4 and the dust removal box 2 is a dust-free cavity, and after air passing through the anode filter barrel 4 enters the dust-free cavity, the air enters the closed space from the air outlet of the dust removal box 2. In order to balance the pressure intensity in the closed air, a one-way air outlet is arranged in the closed space to discharge air outwards. The temperature sensor is arranged in the closed space, and transmits a signal to the heat dissipation system after sensing that the temperature in the closed space reaches a set temperature, and the heat dissipation system is started to extract outside air and convey the outside air into the closed space. And closing the heat dissipation system until the temperature in the closed space is reduced to be below the set temperature or the heat dissipation system is started for a specified time.

After air is pumped into the dust removal box 2, the air flow rate is too high, so that when the air passes through the cathode hairiness net 3, part of dust particles in the air pass through an electron fog area generated by the cathode hairiness net 3 without being combined with electrons due to the too high speed, and the part of dust particles cannot be effectively adsorbed by the anode filter barrel 4, so that the adsorption efficiency of the anode filter barrel is reduced. Therefore, a draft tube 7 is additionally arranged between the air inlet of the dust removing box 2 and the cathode hairiness net 3.

The slow flow pipe 7 comprises an air duct 71 communicated with an air inlet of the dust removal box 2, the other end of the orifice of the slow flow pipe 7 is divided into two flow dividing pipes 72, the orifices of the two flow dividing pipes 72 are opposite, the orifices have the same size and are positioned on the same axis, and the axes of the orifices of the two flow dividing pipes 72 are parallel to the screen surface of the cathode hairiness screen 3. After the outside air enters the air duct 71 from the dust removing box 2, the outside air is divided into two flow dividing pipes 72, when the outside air flows out of the two flow dividing pipes 72, the air flow rate is reduced to the maximum extent by the collision of two air flows, and the decelerated air slowly passes through an electron fog area, so that the proportion of combining dust and electrons is improved. The number of the shunt tubes 72 is not limited, and the deceleration function can also be realized by arranging a plurality of shunt tubes to enable a plurality of air strands to collide.

The shunt tubes are not arranged right opposite to each other, but an included angle is formed between the shunt tubes, so that air is collided to achieve the effect of speed reduction.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
