Description
Technical field
The utility model relates to frequency converter field, particularly relates to a kind of frequency converter cooling device.
Background technology
Often can use frequency converter in production, frequency converter (Variable-frequency Drive, VFD) is application converter technique and microelectric technique, controls the electric control appliance of alternating current motor by changing machine operation supply frequency mode.If want correct use frequency converter, the problem of dispelling the heat must be considered in earnest.The failure rate of frequency converter raises and the rising of exponentially with temperature, and useful life raises and the decline of exponentially with temperature, and ambient temperature raises 10 degree, and frequency converter reduces by half useful life.Existing mode of dispelling the heat to frequency converter has and installs an air-conditioner or large-scale fan in Transducer Room, air-conditioning power consumption is large, and both just dispelled the heat in the outside of frequency converter, and can not directly be dispelled the heat in the inside of frequency converter, therefore radiating effect is not good, and the failure rate of frequency converter is still higher.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition improves prior art, a kind of frequency converter cooling device is provided, the frequency converter cooling device radiating effect solved in current technology is poor, consumes energy high, the frequency converter problem that fault can not effectively control because temperature is high.
For solving above technical problem, the technical solution of the utility model is:
A kind of frequency converter cooling device, comprise frequency converter main body, it is characterized in that, described frequency converter body top sets out air port and device wind direction air outlet blower fan upwards, air inlet is offered in the bottom of frequency converter main body, and device wind direction air inlet blower fan upwards, simultaneously at the interior arrangement wind direction accessory fan upwards of frequency converter main body.Frequency converter cooling device described in the utility model utilizes the air outlet blower fan of frequency converter body top and the air inlet blower fan of bottom frequency converter main body to be become an air-flow air channel upwards, accelerate the speed air flow in frequency converter main body, thus raising radiating effect, make each parts in frequency converter main body can long-acting stable operation.Accessory fan is set in frequency converter main body simultaneously, the airflow direction in frequency converter main body can be stablized, avoid air-flow form vortex in frequency converter main body and all do not discharge, further can improve radiating effect.
Further, described frequency converter main body has screen pack at bottom air inlet mouth place returning apparatus, utilize screen pack blocks dust to enter in frequency converter main body from air inlet, the accumulation of dust can seriously cause heat radiation bad, arranges screen pack and can reduce the impact of dust on heat radiation to greatest extent.
Further, described frequency converter main body has brush at bottom air inlet mouth place returning apparatus, brush is connected with pull bar, pull bar can make brush along the dust on the swept filter screen of frequency converter body floor transverse shifting, avoiding dust to block screen pack causes heat radiation bad, to clear up screen pack without the need to frequency converter lifting being got up, cleaning operation is convenient and swift.
Further, described accessory fan frequency converter body interior at least device have two, stablize the airflow direction in frequency converter main body.
Further, in described frequency converter main body, returning apparatus has temperature sensor, temperature sensor is connected with siren, stablizing of temperature sensor monitors frequency converter body interior, sound, light alarm is sent by siren when temperature is too high, remind staff's emergency processing, avoid failure propagation to cause heavy losses.
Compared with prior art, the utility model advantage is:
Frequency converter cooling device described in the utility model can effectively dispel the heat to frequency converter inside, and in frequency converter, air flow property is good, ensures the long-acting steady operation of frequency converter, reduces failure rate;
The utility model structure is simple, is easy to manufacture, and cost of manufacture is low, high financial profit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of frequency converter cooling device disclosed in the utility model embodiment, improves the radiating effect of frequency converter inside, is discharged by the heat of frequency converter inside fast and effectively, ensures the long-acting stable operation of frequency converter, reduces rate of breakdown.
As shown in Figure 1, a kind of frequency converter cooling device, comprise frequency converter main body 1, frequency converter main body 1 top sets out air port and device wind direction air outlet blower fan 2 upwards, air inlet is offered in the bottom of frequency converter main body 1, and device wind direction air inlet blower fan 3 upwards, and prevent dust from entering frequency converter main body 1 at air inlet device screen pack 5 and affect heat radiation, simultaneously at the interior arrangement wind direction accessory fan 4 upwards of frequency converter main body 1, accessory fan 4 at least device has two, stablize the ascending air direction in frequency converter main body 1, improve radiating effect.
Frequency converter main body 1 has brush 6 at bottom air inlet mouth place returning apparatus, brush 6 is connected with pull bar 7, pull bar 7 can make brush 6 along the dust on the swept filter screen 5 of frequency converter main body 1 bottom surface transverse shifting, pull bar 7 is regularly pulled to utilize dust on the swept filter screen 5 of cleaning brush 6, ensure the usual of air inlet, guarantee that heat radiation is good.
In frequency converter main body 1, returning apparatus has temperature sensor 8, and temperature sensor 8 is connected with siren 9, generation sound, light alarm when temperature anomaly, reminds staff's emergency processing in time, avoids fault spread.
Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection range of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
