The working principle of the invention is as follows:
(1) automatic water adding device
The first button switch SA1 is shifted to the "automatic" position, and the normally open contact SA1-2 of the first button switch is closed. When the temperature sensor 13 detects that the internal temperature of the control room 2 reaches a preset threshold value, the normally open contact WD-1 of the temperature sensor is closed, the coil of the first relay KA1 is electrified, the first normally open contact KA1-1 of the first relay and the second normally open contact KA1-2 of the first relay are closed, the coil of the first contactor KM1 is electrified, the first normally open contact KM1-1 of the first contactor is closed, the coils of the water suction pump 8 and the first delay relay KT1 are electrified, the water suction pump 8 is started, and water is automatically injected into the water cooling cavity 3. After the delay time of the first delay relay KT1 is over, the first normally open contact KT1-1 of the first delay relay is closed, the water suction pump 10 is powered on, the water suction pump 10 is started, and the continuous circulation of cooling water can be realized after a certain amount of cooling water is stored in the water cooling cavity 3, so that the heat dissipation of the control chamber 2 is realized. The liquid level switch 6 is used for limiting the liquid level height in the water cooling cavity 3 and preventing cooling water from entering the control chamber 2 through the air inlet fan 11 to damage control components. When the coil of the first relay KA1 is electrified, the coil of the second contactor KM2 is also electrified, the first normally closed contact KM2-1 of the second contactor is disconnected, the water suction pump 10 cannot be manually controlled to be started through the second button SB2, and the fact that cooling water is always contained in the water cooling cavity 3 of the control chamber 2 under the high-temperature condition is guaranteed. When the temperature in the control room 2 is reduced to be below a threshold value, the normally open contact WD-1 of the temperature sensor is disconnected, the coils of the water suction pump 8, the water suction pump 10 and the second contactor KM2 lose power, the water suction pump 8 and the water suction pump 10 stop working, the first normally closed contact KM2-1 of the second contactor is closed, the water suction pump 10 can be manually controlled to be started through the second button SB2 at the moment, cooling water in the water cooling cavity 3 is drained, the second button SB2 is pressed, the normally open contact SB2-1 of the second button is closed, and the water suction pump 10 is started by power. In the automatic water adding process, the water suction pump 8 is manually controlled to stop working through the first button SB1, the first button SB1 is pressed, the normally closed contact SB1-1 of the first button is disconnected, the water suction pump 8 loses electricity, and water injection into the water cooling cavity 3 is stopped.
(2) Hand water adding
The first toggle switch SA1 is shifted to a manual gear, a self-reset normally open contact SA1-1 of the first toggle switch is closed, a coil of a first contactor KM1 is electrified, a first normally open contact KM1-1 of the first contactor is closed, a water suction pump 8 and a coil of a first time delay relay KT1 are electrified, the water suction pump 8 is started, and water is manually injected into the water cooling cavity 3. When the water level in the water-cooling cavity 3 reaches the height of the liquid level switch 6, the normally closed contact YW-1 of the liquid level switch is disconnected, the coil of the first relay KA1 is powered off, the first normally open contact KA1-1 of the first relay and the second normally open contact KA1-2 of the first relay are disconnected, the coil of the first contactor KM1 is powered off, and the water absorption pump 8 stops working. The water pump 10 can be manually controlled to start through the second button SB2, and the cooling water in the water cooling cavity 3 is drained.
(3) Starting air-cooled heat dissipation
The second toggle switch SA2 is dialed to an 'open' position, a normally open contact SA2-1 of the second toggle switch is closed, a coil of a third contactor KM3 is electrified, a first normally open contact KM3-1 of the third contactor is closed, a suction pump 9 and a coil of a second time delay relay KT2 are electrified, and the suction pump 9 starts to inject external air into the water-cooling cavity 3. After the delay time of the second delay relay KT2, the first normally open contact KT2-1 of second delay relay is closed, and air inlet fan 11 and exhaust fan 12 have got the electricity and have started, and control room 2 realizes the heat exchange with the outside air, when effectively preventing air inlet fan 11 and exhaust fan 12, the not enough negative pressure that forms of air volume in the water-cooling chamber 3, causes control components and parts to damage in pressing the cooling water in the water-cooling chamber 3 into control room 2. After the outside air is cleaned by the cooling water in the water cooling cavity 3, the dust attached to the outside air is deposited in the cooling water, the cleaned outside air is further filtered by the filter plate 4, the water vapor carried out in the water cleaning process is removed by the drying plate 5, and finally the outside air enters the control room 2 through the air inlet fan 11 and the exhaust fan 12 for heat exchange. The second normally open contact KM1-2 of first contactor is established ties between the normally open contact SA2-1 of second button switch and third contactor KM 3's coil, only starts the water-cooling heat dissipation promptly, and the second normally open contact KM1-2 of first contactor is closed after, just can start the air-cooling heat dissipation through second button switch SA2, avoids the outside air that contains the dust directly to get into control room 2, causes the damage to control components and parts. The second button switch SA2 is switched to a 'closed' position, a normally open contact SA2-1 of the second button switch is disconnected, the air suction pump 9, the air inlet fan 11 and the exhaust fan 12 lose power, and the work is stopped.
(4) Humidity detection
In the embodiment of the invention, a water level display 14 is arranged on the side surface of the cabinet body 1, so that an operator can observe the water level in the cold water cavity 3 conveniently when adding water. A water inlet valve 15 is arranged between the water suction pump 8 and the water inlet, an air inlet valve 16 is arranged between the air suction pump 9 and the water inlet, and a water outlet valve 17 is arranged between the water suction pump 10 and the water outlet and used for controlling water inlet, water outlet and air inlet. According to an actual application scenario, the delay time of the first delay relay KT1 can be set to be 10-180 s, the delay time of the second delay relay KT2 can be set to be 10-60 s, in the embodiment of the invention, the delay time of the first delay relay KT1 is 60s, and the delay time of the second delay relay KT2 is 20 s.
The invention has two heat dissipation modes of air cooling and water cooling, can improve the heat dissipation efficiency of the control cabinet, can reduce the damage of dust to control components in the control cabinet, and prolongs the service life of the control components. The water cooling cavity 3 is arranged at the periphery of the control chamber 2 and exchanges heat with the control chamber 2 through cooling water; the devices in the control chamber 2, especially the large devices with large heat productivity, are mostly arranged on the side wall and the back plate of the control chamber 2, and the heat exchange efficiency is higher because the heat conductivity of water is better than that of air, and the temperature of the control chamber 2 can be more efficiently reduced through a water cooling mode; the temperature at the center of the control room 2 can be dissipated through an air cooling mode, external air needs to enter the water cooling cavity 3 first, and then enters the control room 2 after being washed by cooling water to remove dust, filtered by the filter plate 4 and dried by the drying plate 5, and the air entering the control room 2 is dried and clean to perform heat exchange, so that the central temperature of the control room 2 can be reduced, and the damage to control components inside the control room 2 can be avoided.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
