Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of elevator to use the explosion-proof frequency converter cooling system; Its operation principle is to be fixedly connected the one side that said frequency converter is provided with silicon rectifier after smearing heat radiation fat through contact-making surface in said explosion-proof electric apparatus casing; The corresponding outer contacting face of contact-making surface is smeared the said frequency converter fin of fixed connection behind the heat radiation fat in said explosion-proof electric apparatus casing and the said silicon rectifier; The heat that silicon rectifier is loose in the frequency converter can in time be dissipated; The heat that is loose when the too high fin of temperature in the frequency converter fully the time, is restarted explosion-proof fan the heat in the frequency converter is extracted out inadequately.
Below in conjunction with embodiment and embodiment the utility model is done further detailed explanation.
As shown in Figure 1; A kind of elevator is used the explosion-proof frequency converter cooling system; Comprise explosion-proof electric apparatus casing 1, frequency converter heat abstractor and be provided with the frequency converter 3 of silicon rectifier 31, said frequency converter heat abstractor comprises fin 21, temperature measuring equipment 22, temperature controller 23 and explosion-proof fan 24; Contact-making surface is fixedly connected the one side that said frequency converter 3 is provided with silicon rectifier 31 after smearing heat radiation fat in the said explosion-proof electric apparatus casing 1; The corresponding outer contacting faces of contact-making surface are smeared the said frequency converter fin 21 of fixed connection behind the heat radiation fat in said explosion-proof electric apparatus casing 1 and the said silicon rectifier 31; Said temperature measuring equipment 22 detects said fin 21 temperature and is transferred to said temperature controller 23; The said explosion-proof fan 24 of said temperature controller 23 controls.Wherein, be provided with Explosion proof joint 4 between said explosion-proof fan 24 and the said explosion-proof electric apparatus casing 1; The temperature upper limit that said temperature controller 23 is allowed according to said frequency converter 3 is set and is started said explosion-proof fan 24; Said temperature controller 23 is set according to the lowest temperature of said fin 21 and is stopped said explosion-proof fan 24.
When elevator is worked; Frequency converter 3 can move up and down at each floor gap by its drive motor drives cars of control, and its inner silicon rectifier 31 can distribute heats during frequency converter 3 work, if untimely draining; Will cause it to damage, also can influence other electronic devices and components.Therefore; The frequency converter cooling system of the utility model is fixedly connected after the heater element silicon rectifier 31 and the contact-making surface of explosion-proof electric apparatus casing 1 are smeared heat radiation fat; After the another side of the corresponding explosion-proof electric apparatus casing 1 of its contact-making surface is also smeared heat radiation fat, be fixedly connected with frequency converter fin 21 then, like this silicon rectifier 31 of frequency converter 3 distribute heat will pass to frequency converter fin 21 through the contact-making surface of itself and explosion-proof casing 1 and dissipate.In addition; When temperature raise or frequency converter 3 in temperature raise when too fast; For prevent in the explosion-proof electric apparatus casing 1 heat through fin dissipate abundant inadequately, when the temperature measuring equipment 22 on fin 21 detects the temperature overshoot limit of fin 21, will send the temperature signal that detects to temperature controller 23; Temperature controller 23 will be controlled explosion-proof fan 24 startup work, and the hot gas in the frequency converter 3 is extracted out along a discharge duct and Explosion proof joint 4; When the temperature of fin 21 was lower than set point, temperature measuring equipment 22 passed to temperature controller 23 with detected temperature signal, and temperature controller 23 can be controlled explosion-proof fan 24 again and quit work, thereby had practiced thrift the energy and reduced consumption.
More than be exactly the radiating principle of the elevator of the utility model with the explosion-proof frequency converter cooling system.
