And thirdly, when the commercial power is abnormal, the EPS fire-fighting emergency power supply enters an inversion working mode, and the controller in the power box controls the storage battery to output current to the emergency power supply and output alternating current through the inverter at the inversion part, so that the current can be output to a user load.
Fourthly, when the EPS fire-fighting emergency power supply is in an inversion working mode, heat generated by the working of electrical components in the power supply box is transferred to one end, located on the inner side wall of the power supply box, of the heat dissipation copper pipe, the easily-evaporated liquid in the heat dissipation copper pipe absorbs heat and evaporates after being heated, the generated steam moves to one end, located on the outer side wall of the power supply box, of the heat dissipation copper pipe and then is cooled to emit heat and condense, the easily-evaporated liquid after being condensed returns to one end, located on the inner side wall of the power supply box, of the heat dissipation copper pipe through the capillary core, and the temperature inside.
Fifthly, when the temperature in the power box is higher, the cooling water circulation box inputs cooling water into the water-cooling coil pipe through the water outlet pipe, the cooling water can be quickly condensed by quickly absorbing heat in the steam at one end of the outer side wall of the power box, which is moved to the heat dissipation copper pipe, in the process of passing through the water-cooling coil pipe, and meanwhile, the fan is started and drives air circulation, so that the heat in the heat dissipation cavity can be quickly discharged through the heat dissipation holes along with air flow.
