Description
Technical field
The utility model is related to a kind of motor frame more particularly to a kind of motor frames with the convex block to heat conduction.
Background technology
Motor is a kind of by electromagnetic induction, converts electric energy to the device of kinetic energy.In the mistake for converting electric energy to kinetic energy
Cheng Dangzhong, electric current can be connected in stator winding, use generation magnetic effect of electric current.It, can be because of coil sheet but during conducting
The resistance that body is included so that (being, for example, copper loss or iron loss) can be lost in electric current, and then generates extra thermal energy.These heat
Destruction can be generated, and then influence the normal operation of motor to the element inside motor.
It is stated in detail, the front perspective view of the motor frame of the prior art is shown also referring to Fig. 1 to Fig. 2, Fig. 1；Fig. 2
Show A-the A sectional views of Fig. 1.As shown in the figure, the prior art, which provides a kind of motor frame PA1, includes a frame body PA11
With multiple radiating fin PA12 (one of which is only indicated in figure).In frame body PA11 peripheral hardwares, there are four fin setting units
PA111, PA111a, PA111b and PA111c are equipped between three fin setting units PA111, PA111a and PA111b wherein
Two connection path PAT1 (one of which is only indicated in figure).Connection path PAT1 is corresponding in a channel of frame body PA11
A wall PA112 and channel outer wall PA113.
Referring to Fig. 3, Fig. 3 shows the operating condition schematic diagram of the motor frame cooperation motor cores component of the prior art.
As shown in the figure, motor cores component PA2 includes one first fan PA21, one second fan PA22, a stator PA23, a rotor
PA24, a drive end bearing bracket PA25, a backside lid PA26, an external fan PA27 and a fan housing PA28.Rotor PA24 offers a rotor
Heat dissipation channel PAT2.First fan PA21 and the second fan PA22 is respectively arranged at the central shaft of rotor PA24 (figure does not indicate)
Both ends.Drive end bearing bracket PA25 and backside lid PA26 is covered on the both ends of frame body PA11 so that an envelope is formed in frame body 11
Close space.External fan PA27 is set to one end of rotor PA24 central shafts, and position is outside frame body PA11.Fan housing PA28 is covered
External fan PA27.
One motor PA100 includes motor frame PA1 and motor cores component PA2, when motor PA100 in the running, electric energy
It is converted into that during kinetic energy extra thermal energy can be generated so that the temperature raising of motor internal element.When rotor PA24 is operated
When, the first fan PA21 and the second fan PA22 can drive frame body PA11 inner airs to flow, and then generate an inside and dissipate
Thermal current PAF1.Internal heat dissipating air-flow PAF1 can absorb the thermal energy in rotor heat dissipation channel PAT2, make thermal energy with internal heat dissipating
Air-flow PAF1 is passed in connection path PAT1.It, can be further by the thermal energy of connection path PAT1 by the mode of heat transfer
It is transferred to outside connection path PAT1.Finally, thermal energy is escaped by an external cooling air-flow PAF2 caused by external fan PA27
It is dissipated to external environment.
However, the connection path PAT1 as interior gas circulation cooling channel reduces the quantity for leading to radiating fin PA12,
The region for lacking radiating fin PA12 causes connection path PAT1 to generate larger thermal resistance.And connection path PAT1 can block exogenous wind
Fan the external cooling air-flow PAF2 that PA27 is generated so that external cooling air-flow PAF2 generates one windward after flowing through radiating fin PA12
Face and the difference of a leeward, the heat dissipation effect of leeward is poor compared with windward side, therefore corresponds in the connection path PAT1 of leeward
Easily generate the higher hot spot of temperature so that the Temperature Distribution of motor frame PA1 is unequal, and heat dissipation effect is had no significantly
It helps.
Utility model content
In view of in the prior art, connection path causes radiating fin quantity to reduce, and causes external cooling air-flow stream
The difference of windward side and leeward is generated after radiating fin, the connection path content for corresponding to leeward is caused to be also easy to produce temperature
Higher hot spot so that motor cores component is located in an environment of high temperature for a long time, thus is inevitably destroyed to motor generation.
In addition, hot spot can also so that the temperature branch in motor frame is unequal, being harmful can be said for the heat dissipation effect of motor entirety
It is unhelpful.
