Further, the litzendraht wire be provided with it is a plurality of, each litzendraht wire along conducting heat seat circumference arrange.
Further, the natural length of the litzendraht wire is more than radiating the distance between hoof foot and conducting heat seat.
Further, the material of the litzendraht wire is copper.
Further, also including ball head, half gland and elastic component, the ball head, half gland and radiating hoof foot composition ballHinge is secondary, and the radiating hoof foot freely swings relative to ball head, and one end of the elastic component is connected with motor body, the other end andBall head connects, and the ball head is installed in the axis hole of the conducting heat seat that one end insertion of elastic component is coordinated with which, the bulbAxle slides in the axis hole of conducting heat seat.
Further, one end of the ball head arranges fluted, and the elastic component is located in the groove.
Further, the elastic component is spring.
Further, the vacuum motor conducting heat is located at vacuum cavity inside the shell, in the elastic component and the work of ball headWith under, the radiating hoof foot is contacted with vacuum cavity shell, gives vacuum cavity shell by the heat transfer that motor is produced.
Beneficial effects of the present invention are as follows：
(1), all parts of motor conducting heat of the invention are made using the high materials processing of heat conductivity, using copperThe high thermal conductivity of litzendraht wire realizes the conduction of heat between relative motion part so that the motor conducting heat of the present invention meetsThe conduction and release of heat are produced under vacuum environment in motor operation course, the work for realizing motor radiating under vacuum environment willAsk, with higher engineering application value.
(2), the axis hole that ball head of the invention can be along conducting heat seat in the presence of elastic component slides axially, and is easy to rootAccording to the length of the distance between motor body and vacuum cavity shell adjust automatically conducting heat.
(3), ball head of the invention, radiating hoof foot and half gland composition typed ball bearing pair so that radiating hoof foot is relative to bulbAxle freely can swing, it is ensured that radiating hoof foot is in close contact with vacuum cavity shell, improve heat-conducting effect.

Specific embodiment
In order that those skilled in the art more fully understand technical scheme, it is with reference to the accompanying drawing of the present invention, rightTechnical scheme carries out clear, complete description, and based on the embodiment in the application, those of ordinary skill in the art existOther the similar embodiments obtained on the premise of not making creative work, should all belong to the scope of the application protection.
Embodiment one：
As depicted in figs. 1 and 2, a kind of vacuum motor conducting heat, including conducting heat seat 1, litzendraht wire 5 and radiating hoof foot 7, instituteConducting heat seat 1 is stated on motor body 9, one end of the litzendraht wire 5 is connected with conducting heat seat 1 by the first fixture 10Connect, the other end is connected with radiating hoof foot 7 by the second fixture 6, and first fixture 10 and the second fixture 6 are larynxHoop, the litzendraht wire 5 is provided with a plurality of, and 5 numbers of litzendraht wire of the present embodiment can be arranged on more than eight, 5 edge of each litzendraht wireThe arrangement of 1 circumference of conducting heat seat, the natural length of the litzendraht wire 5 is more than the distance between radiating hoof foot 7 and conducting heat seat 1,So that by pulling force when distance of the litzendraht wire 5 between radiating hoof foot 7 and conducting heat seat 1 is maximum, the material of the litzendraht wire 5 isCopper, copper litz wire heat conductivity are high, with good pliability.
, using the material processing and fabricating that heat conductivity is high, during work, motor is due to work for all parts of conducting heatElectric current produces heat, and the heat that motor is produced is conducted to conducting heat seat 1 by contact surface, and the heat of conducting heat seat 1 passes through severalCopper litz wire 5 conducts the heat of motor to radiating hoof foot 7, and radiating hoof foot 7 conducts heat to vacuum in close contact therewithShell cavity 8, the outer surface of vacuum cavity shell 8 is by heat diffusion in outside air environment.
Embodiment two：
Do not repeating where the composition and annexation of the present embodiment are identical with the present embodiment one, difference is alsoIncluding ball head 3, half gland 4 and elastic component 2, the ball head 3, half gland 4 and radiating hoof foot 7 constitute typed ball bearing pair, described to dissipateHot hoof foot 7 freely swings relative to ball head 3, and the vacuum motor conducting heat is located in vacuum cavity shell 8, in the elasticityIn the presence of part 2 and ball head 3, the radiating hoof foot 7 is contacted with vacuum cavity shell 8, and the heat transfer that motor is produced is givenVacuum cavity shell 8, one end of the elastic component 2 are connected with motor body 9, and the other end is connected with ball head 3, the ball head3 one end arranges fluted, and the elastic component 2 is located in the groove, and the elastic component 2 is spring, and the ball head 3 is installedIn the axis hole of the conducting heat seat 1 that one end insertion of elastic component is coordinated with which, the ball head 3 is sliding in the axis hole of conducting heat seat 1Move, ball head 3 and conducting heat seat 1 can enter line slip in the presence of elastic component 2 vertically within the specific limits, according to motor sheetThe length of the distance between body 9 and vacuum cavity shell 8 adjust automatically conducting heat.
In the course of work, conducting heat is arranged on motor body 9, after firmly installing by conducting heat seat 1, installs vacuum chamberBody case 8, as the distance between vacuum cavity shell 8 and motor body 9 are less than conducting heat greatest length, ball head 3 is relativeAxially it is moved in conducting heat seat 1, spring is compressed, radiate in the presence of spring force hoof foot 7 and vacuum cavity shell 8It is in close contact, there is copper litz wire good flexibility to produce bending as shown in Figure 1.
Motor in running conducts the heat of generation to conducting heat seat 1 in close contact therewith, and conducting heat seat 1 leads toSeveral copper litz wires in close contact therewith are crossed by most heat transfers to the hoof foot 7 that radiates, heat is passed by radiating hoof foot 7 againVacuum cavity shell 8 in close contact therewith is directed at, vacuum cavity shell 8 has larger area of dissipation, while its outer surfaceThe heat that conduction comes in an atmosphere, rapidly can be discharged, so as to realize the mesh of motor radiating under vacuum environment by exposure's.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrappedContaining an independent technical scheme, this narrating mode of description is only that those skilled in the art should for clarityUsing description as an entirety, the technical scheme in each embodiment can also Jing it is appropriately combined, form those skilled in the artUnderstandable other embodiment.
