Further, the quantity of described fan is two.On the top that can be arranged on power distribution cabinet and beneath.
The utility model tool has the following advantages: the utility model selectively can use fan or air-conditioning and fan to dispel the heat according to temperature, long time running fan or air-conditioning is avoided during low temperature, high temperature can add that air-conditioning together dispels the heat by fan again, and combination heat radiation can effectively reduce power distribution cabinet temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is arranged on power distribution cabinet,
Fig. 2 is the structural representation of the utility model temperature-sensitive electric-control system.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
Refer to Fig. 1, Fig. 2, the utility model is a kind of anti-overheated power distribution cabinet, the cabinet door 2 that power distribution cabinet comprises cabinet 1 and is connected with cabinet, on described cabinet, end face and bottom surface are provided with fan 3, described cabinet inside is provided with air-conditioning internal machine 4, described air-conditioning internal machine 4 comprises interconnective air outlet 5, evaporator and throttle part, and described cabinet 1 outside is provided with the outdoor machine of air-conditioner 8 that air-conditioning internal machine connects, the condenser that described outdoor machine of air-conditioner 8 comprises compressor and is connected with compressor.
Be provided with a temperature-sensitive electric-control system in described cabinet, as shown in Figure 2, described temperature-sensitive electric-control system is connected with fan, air-conditioning internal machine, outdoor machine of air-conditioner.Temperature-sensitive electric-control system includes thermistor RL, first voltage comparator U1 and the second voltage comparator U2, thermistor RL one end ground connection, one end of another termination reference resistance R1 of thermistor RL, another termination voltage source V CC of reference resistance R1, the other end of thermistor RL is also connected with an input of the first voltage comparator U1 and an input of the second voltage comparator U2, another input of first voltage comparator U1 is connected with the first reference voltage, another input of second voltage comparator U2 is connected with the second reference voltage, the output of the first voltage comparator U1 is connected with fan, the output of the second voltage comparator U2 is connected with air-conditioning internal machine and outdoor machine of air-conditioner, the resistance of described thermistor is directly proportional to temperature, and described first reference voltage is less than the second reference voltage.
Operation principle of the present utility model is: temperature-sensitive electric-control system can be responded to temperature, when temperature is in lower temperature, as during lower than 15 °, thermistor resistance is lower, the voltage of thermistor is lower, is less than the first reference voltage and the second reference voltage, then two voltage comparators all do not export, then fan and air-conditioning do not work, and to avoid under low temperature fan or air-conditioning work and cause the life-span to reduce.When temperature is in general temperature, during as 15 °-30 °, now thermistor resistance is lower, the voltage of thermistor is lower, be greater than the first reference voltage and be less than the second reference voltage, then the first voltage comparator have output and the second voltage comparator no-output, temperature-sensitive electric-control system 13 controls fan 3 and carries out heat discharging operation.When temperature is raised to higher temperature, as when temperature is higher than 35 °, then thermistor voltage is greater than the second reference voltage, second voltage comparator also starts to export, then temperature-sensitive electric-control system 13 control air-conditioning internal machine 4 and outdoor machine of air-conditioner 8 carry out refrigeration running, when carrying out refrigeration running, the refrigerant gas of low-temp low-pressure is sucked by compressor the refrigerant gas that rear pressurization becomes HTHP, the liquid of warm high pressure during the refrigerant gas of HTHP becomes after by condenser condenses, the liquid of middle temperature high pressure becomes the liquid of low-temp low-pressure again after throttle part reducing pressure by regulating flow, the liquid refrigerant of low-temp low-pressure absorbs heat in evaporator, and (room air is through the cooled cooling of evaporator surface for the gas becoming low-temp low-pressure after evaporation, reach the object that indoor temperature is declined), the refrigerant gas of low-temp low-pressure is sucked by compressor again, circulation like this.
By temperature-sensitive electric-control system according to the regulation and control of temperature to fan and air-conditioning, make fan and air-conditioning not need long time running work, effectively can extend the useful life of power distribution cabinet.Electric fan and air-conditioning can be driven to dispel the heat in the lump during high temperature simultaneously, greatly reduce the situation that power distribution cabinet is overheated.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
