[0002] In modern navigation, in order to improve the overall electrical management convenience of the ship, a central integrated power distribution control system is usually adopted. However, this makes many electrical lines and power distribution management equipment relatively concentrated in the control room. Therefore, as the electrical integration is high, the heat generated by the equipment in the overall power distribution system also increases and becomes more and more concentrated, so heat dissipation is required. At present, the power distribution system mainly uses forced air cooling to dissipate heat. The heat dissipation position of the power distribution system on board is close to the sea surface, which causes the water vapor and fog stirred up by the sea surface to easily pollute the air intake of the cooling device, resulting in a reduction in the service life of the cooling device. In view of this, in-depth research was conducted on the above-mentioned problems, resulting in this case. Utility Model Content

The present application discloses an external heat dissipation mechanism of a power distribution control system, which specifically includes an external heat dissipation casing 1.

An enhanced heat exchange surface 31 is provided on one side of the water storage tank 3, and a plurality of rectangular heat exchange grooves 32 are provided on the enhanced heat exchange surface 31. The high-speed heat exchange air flows through the enhanced heat exchange surface 31 to take away the heat, thereby reducing the water temperature in the water storage tank 3.

[0021] According to the instruction manual Figure 1-3 It can be seen that the air supply pipeline 9 is connected to the flow diverter 6 by a flange 61, and a ventilation fan window 5 is provided at the end of the air supply pipeline 9. The ventilation fan window 5 is a double-layer structure. The double-layer structure of the ventilation fan window 5 reduces the probability of seawater entering the ventilation port. The heat exchange air is supplied to the flow diverter 6 through the air supply pipeline 9 by the inner axial flow fan 4. At the same time, an anti-corrosion plug-in 63 is provided on one side of the inner axial flow fan 4 to absorb corrosive water vapor in seawater, so as to effectively protect the inner axial flow fan 4 and the electrical equipment in the cabin;

[0022] According to the instruction manual Figure 1It can be seen that the above-mentioned anti-corrosion plug-in 63 includes a sleeve with filter screens at both ends, one end of the sleeve is fixed to one end of the internal axial flow fan 4, and the filter screen structure of the sleeve ensures that air can flow through the sleeve. A loose and porous water-absorbing sponge block is arranged in the sleeve to absorb water vapor flowing into the air supply pipeline 9.

[0028] In the specific implementation process, the heat exchange coil 22 is connected to both ends of the circulating power pipeline 8, and a complete circulating pipeline is formed by the circulating power pipeline 8 and the heat exchange coil 22. A heat exchange water pump is connected to the circulating power pipeline 8.

The water tank 3 in the external heat dissipation casing is in contact with the high-pressure air to complete the heat exchange, so that the air takes away the heat on the water tank 3, and then the heat is taken away by the heat exchange pipe between the water tank 3 and the heat exchange plate surface.
