Description
Technical field
The utility model relates to a kind of Intelligent cooling device, specifically a kind of Intelligent cooling device for aviation inverter.
Background technique
At present, aviation inverter heat transmission be ac fan, the power supply of ac fan is provided by the output AC electricity of inverter that (output of inverter is 115V, the Ac of 400Hz), when inverter works, fan is just started working, and inverter used on aircraft, in most of the cases, with load all very little, have or even work long hours under idle condition.In this case, the heating value of inverter work is very little, but fan is started working, and the power of fan is generally 20 ~ 50W, like this, just greatly reduces the working efficiency of inverter.Simultaneously, also reduce the working life of ac fan, for the electrical equipment on aircraft, higher requirement is had to efficiency and working life, therefore, design a kind of Intelligent cooling device of aviation inverter, when temperature in inverter reaches needs time, fan is started working, time temperature lowers, fan quits work, and is necessary.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of Intelligent cooling device of aviation inverter, when aviation inverter is unloaded or be with little year, ac fan does not turn, when inverter band is fully loaded or band year works long hours, fan is started working, and is conducive to the efficiency improving inverter.
For reaching above-mentioned purpose, the Intelligent cooling device of a kind of aviation inverter of the utility model, comprise inverter, the Heat sink that inverter circuit board lower end in described inverter is provided with, described Heat sink upper end and inverter circuit board joint are provided with the switch MOS pipe be connected with inverter, described switch MOS pipe is close on Heat sink, rear plate in described inverter is provided with ac fan, carry out air-cooled to internal component during work, the power line of described ac fan is by accessing the out-put supply of inverter after wired in series connection temperature relay, described temperature relay is close on Heat sink.
Further, described inverter exports the Ac of 115V, 400Hz.
Further, described temperature relay contact is normally open contact.
The beneficial effects of the utility model are as follows: switch MOS pipe generates heat, and when temperature on Heat sink does not reach setting value, temperature relay is not connected, and ac fan does not work; When switch MOS pipe continues heating, when on Heat sink, temperature reaches setting value, temperature relay is connected, and ac fan switches on power, and ac fan is started working, and lowers the temperature to inverter; If temperature drops to setting value, temperature relay disconnects, and ac fan quits work; Like this, ac fan just can not start when inverter internal temperature is not high, starts working when temperature arrives setting value, thus improves the efficiency of inverter, extends the working life of ac fan.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of aviation inverter intelligent cooling unit;
Fig. 2 is the circuit theory diagrams of aviation inverter intelligent cooling unit.
Description of reference numerals: 1-switch MOS pipe; 2-Heat sink; 3-inverter circuit board; 4 – temperature relays; 5-ac fan; 6-wire.
Embodiment
Below in conjunction with drawings and Examples, to above-mentioned being described in more detail with other technical characteristics and advantage of the utility model.
As shown in Figure 1.The inverter circuit board 3 of inverter internal exports 115V, 400Hz Ac, by wire 6, cut-in temperature relay 4, incoming transport fan 5 again, power supply is provided to ac fan 5, what inverter internal temperature was the highest is switch MOS pipe 1, dispel the heat by the surface that switch MOS pipe 1 is attached to Heat sink 2, temperature is experienced in the side that temperature relay 4 is close to Heat sink 2, when inverter is unloaded or be with work in little year, switch MOS pipe 1 temperature is not high, Heat sink 2 side temperature is not high yet, temperature relay 4 normally open contact does not trigger, ac fan power supply 5 is not connected, do not work.When inverter work is fully loaded or long-time band carries work, switch MOS pipe 1 heating value is large, heat is transmitted by Heat sink 2, and high temperature experienced by the temperature relay 4 being attached to Heat sink 2 side, and normally open contact closes, ac fan 5 switches on power and starts working, after load laid down by inverter, switch MOS pipe 1 generates heat and gradually reduces, and now temperature relay 4 contact disconnects, ac fan 5 deenergization, quits work.
As shown in Figure 2, the utility model controls ac fan power connection by temperature relay and realizes intelligent cooling effect with shutoff, temperature relay contact is normally open contact, when inverter is unloaded or be with little load, heating value is little, and temperature relay contact does not trigger, for opening state, now, ac fan does not connect power supply, does not work; When inverter works long hours, or band full load, heating value is large, and temperature relay contact closes by high temperature, and ac fan switches on power, and starts working; If temperature declines in inverter, temperature relay contact disconnects, and ac fan power cut-off, fan quits work again.Like this, just can realize monitoring inverter internal temperature in real time by temperature relay, coordinate open and close ac fan thus realize intelligent refrigerating function.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
