The heat sink further comprises a temperature sensor, and the temperature sensor is connected with a singlechip controller arranged outside the air conditioner. When the local heat sink is in use, the blowing device faces to a bearing box and is mounted on a bearing close to an end cover of the electric motor, so as to forcibly dissipate heat of the bearing of the electric motor through air blowing, and evidently improve the heat dissipation effect. The local heat sink not only slightly changes the original structure of the electric motor, but also automatically controls the starting of the air conditioner to reduce the electricity utilization cost; and the local heat sink has the advantages of simple and reasonable structure, convenient assembly and disassembly, and wide application range.

Description

The local heat abstractor of a kind of motor

One, technical field:

The utility model relates to a kind of motor heat abstractor, particularly a kind of device that utilizes air-conditioning motor to be carried out local heat radiation.

Two, background technology:

Now the radiating mode of motor is the heat radiation of drying of the fan that is contained in axle head, and the drawback of this traditional radiating mode maximum is exactly the temperature that is difficult to reduce the bearing of motor position, the bearing of especially close gearing one side.Exactly because bearing of motor position temperature drift causes bearing oil to run off, bearing locking when serious and cause motor to burn.According to statistics, have 35% in the accident that now motor damages at least because bearing temperature is directly too high or cause indirectly.Therefore, the radiating mode of motor exists many defectives to need to be resolved hurrily now.

Three, summary of the invention:

1, goal of the invention:

The utility model provides a kind of motor heat abstractor, its objective is on the basis that does not change existing motor radiating mode, adopt brand-new structural design heat abstractor, can solve the temperature too high and problem that causes motor to burn in the existing ubiquitous position of bearings of motor radiating mode after the installation targetedly, thereby prolong the useful life of motor.

2, technical scheme:

The utility model is achieved through the following technical solutions:

The local heat abstractor of a kind of motor, it is characterized in that: this heat abstractor comprises air-conditioning, pipeline and blowing device, one end of pipeline is arranged on the air outlet place of air-conditioning, and the other end of pipeline is connected with blowing device, and a side end face of blowing device is provided with blowing mouth; This heat abstractor also comprises temperature sensor, and the temperature sensor singlechip controller outer with being arranged on air-conditioning is connected.

Above-mentioned blowing device integral body is the circle ring column of hollow, is connected and composed by the semicircular ring cylinder of two symmetries, and the connected mode between the semicircular ring cylinder adopts pegs graft or bolt connects.

The end face of described blowing device one side is provided with the blowing mouth of 4 symmetries, blowing mouth be shaped as arcuate structure.

Above-mentioned temperature sensor is installed in the motor protecgulum near on the position of bearing.

3, advantage and effect:

The utility model provides a kind of motor heat abstractor, its principle is exactly on existing motor radiating mode basis of invariable, one air-conditioning is set in addition, the cold wind that air-conditioning produces is forced the blowing heat radiation by the pipeline of good heat insulating to the position of bearings of motor, and this brand-new local radiating mode is compared with existing motor has following advantage:

1, because the temperature of bearing of motor position far above other positions, adopts the technical solution of the utility model to force the blowing heat radiation at the position of bearings specially with the cold wind that blows out of air-conditioning, radiating effect obviously promotes.

2, this radiating mode of the utility model does not change the original structure of motor, has only just increased air-conditioning and pipeline thereof, increases its feasibility and adaptability greatly, especially is applicable on workplace ambient temperature height and the high power motor.

3, can realize automatic control, this heat abstractor of the present utility model is provided with temperature sensor, can be according to different actual needs, as: factors such as the significance level of ambient temperature, work, Financial cost are controlled the startup of air-conditioning, thereby the amount of saving energy reduces electric cost.

Five, embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, the local heat abstractor of a kind of motor of the utility model, it is characterized in that: this heat abstractor comprises the pipeline 2 and the blowing device 3 of air-conditioning 1, good heat insulating, one end of pipeline 2 is arranged on the air outlet place of air-conditioning 1, the other end of pipeline 2 is connected with blowing device 3, and a side end face of blowing device 3 is provided with blowing mouth 4; This heat abstractor also comprises temperature sensor 5, temperature sensor 5 singlechip controller 6 outer with being arranged on air-conditioning 1 is connected, during use temperature sensor 5 is installed in motor protecgulum 8 near on the position of bearing, makes temperature sensor 5 detected bearing portion temperature more accurate.

Blowing device 3 integral body are the circle ring column of hollow, be that semicircular ring cylinder 7 by two symmetries can separating along the A-A direction connects and composes, connected mode between these two semicircular ring cylinders 7 can adopt pegs graft or the bolt connection, is convenient to so in use it is installed on the bearing.Be provided with the blowing mouth 4 of 4 symmetries on the end face of blowing device 3 one sides, blowing mouth 4 is the ring arc, and it is more even that the cold wind that it is blown out is set like this.

The utility model in use, as shown in Figure 2, blowing device 3 is installed on the motor protecgulum 8 of bearing housing, because the temperature of motor when work position of bearings is far above other positions, and just can be thereby do so directly to position of bearings blowing raising radiating effect.Air-conditioning 1 starts cold wind that the refrigeration back produces and blows out from the air outlet of air-conditioning 1, arrives the blowing mouth 4 of blowing devices 3 by the pipeline 2 of good heat insulating, and the blowing heat radiation is forced in the position of bearings of motor.

The utility model is the operating state of control air-conditioning 1 automatically, rely on its original radiating mode to dispel the heat behind the motor start-up, running along with motor, position of bearings temperature near gearing raises gradually, original radiating mode is difficult to reduce the temperature of position of bearings, at this moment, when being installed in temperature that motor protecgulum 8 detects the bearing of motor position near the temperature sensor 5 on the positions of bearings and being higher than 80 ℃, send detection signal to singlechip controller 6, singlechip controller 6 sends instruction and makes air-conditioning 1 refrigeration of starting working, the cold wind that blows out from the blowing mouth 4 of blowing device 3 is directly to the heat radiation of drying of bearing of motor position, work simultaneously with the original heat abstractor of motor, radiating effect promotes obviously; When the temperature that detects the bearing of motor position when temperature sensor 5 is lower than 80 ℃, send detection signal to singlechip controller 6, singlechip controller 6 sends instruction quits work air-conditioning 1, at this moment, the original heat abstractor of motor works on motor is dispelled the heat, thereby reached the amount of saving energy, reduced the purpose of electric cost.

Because the temperature of position of bearings is higher relatively during motor work,, the fan power of air-conditioning 1 suitably can be strengthened to satisfy requirement its wind speed for heat radiation better; Cooling pore or fin also can be set on the bearing of motor case; Perhaps cover and set up cooling line, thereby further promote radiating effect in motor terminal.

The utility model structural design advantages of simple, cost is low, feasibility is high, applied widely, especially be applicable on the high and powerful motor of workplace ambient temperature, be easy to apply.
