Heat transfer mechanism on the secondary side of the motor

The present invention relates to motors, and more particularly to a heat transfer mechanism suitable for secondary sides of a motor co-constructed with a motor stator.

The tube body is formed on the circumferential side of the member to be heat-dissipating, so that the fluid flows in the flow channel, and the heat energy is taken out to the extent that the heat dissipation effect is achieved, which is a well-known common technology, such as the first figure and the first In the figure shown in the figure, it is attached to the seat (1) on the secondary side of the linear motor. The groove (3) is arranged along both sides of the magnet (2), and the two tubes (4) are respectively clamped and fixed. In each of the grooves (3), a flow path is formed on the seat (1) to allow the external fluid to continuously flow therein for the purpose of dissipating heat, and at the same time, by the notch of the groove (3) So that the thermal energy outside the notch is radiated to the tube body (4) to dissipate.

The above-mentioned conventional technique discloses that the tube (4) conducts heat energy to the seat (1) which is directly contacted by the engagement, and at the same time allows the radiation of the heat energy by the notch of the groove (3), but The seat (1) is usually made of materials such as epoxy resin or polyurethane. It does not have good thermal conductivity. Although it is not easy to heat up, it is difficult to cool down, resulting in the tube body (4) only being able to directly contact the local range. Providing a plurality of conductive effects, it is difficult to achieve a good heat dissipation effect for the overall configuration of the secondary side of the linear motor, and at the same time, the technical means for integrally forming the groove (3) in the seat (1) is not In the case of the members of the groove, that is, without a suitable joint structure, the arrangement of each of the tubes (4) is not convenient for industrial applications.

Therefore, the main object of the present invention is to provide a heat transfer mechanism on the secondary side of the motor, which is suitable for being disposed between the secondary side of the motor and its attached base, and has good thermal conductivity by the heat transfer member. The metal body transmits thermal energy to the metal body from the adjacent components on the circumferential side, and has a good combination structure between the metal body and the adjacent components, which makes the manufacturing assembly more convenient.

Therefore, in order to achieve the above object, the heat transfer mechanism on the secondary side of the motor provided by the present invention is disposed between the stator member and the attached base thereof, and is provided with at least one heat transfer member, and the heat transfer member is respectively Adjacent to the stator member and the base, heat energy is conducted into the heat transfer member.

The heat transfer member is directly or indirectly attached to the stator member and the base by a first side surface and a second side surface of the metal body.

At the same time, in order to ensure that the thermal energy transmitted to the metal body can be quickly separated, the heat transfer member further includes a flow path disposed inside the metal body, and a passage for the external fluid to flow and make the flow An opening communicating with the outside is formed at both ends of the metal body to allow fluid to flow in and out.

Furthermore, in order to further improve the heat transfer capability, the metal body can be directly or indirectly attached to both sides of the stator member by the first side surface and the third side surface, and the contact area is increased to increase the heat energy. Conduction.

In addition, in order to reduce the transfer of thermal energy to the susceptor via conduction, the heat transfer member is a pad body, and is sandwiched between the stator member and the base, so that the stator member and the pedestal are separated from each other. A gap is formed to reduce the transfer of thermal energy, and the base is further protected from thermal energy to ensure the dimensional stability.

In this case, in order to stabilize the combination between the stator member and the base, the system can be increased. The number of the heat transfer members is two, and is spaced apart from each other and disposed between the two sides of the stator member and the base.

Further, the heat transfer member is extruded into an integrally formed article of aluminum or aluminum alloy. In a specific configuration, the metal system further includes a wing portion and a body juxtaposed to each other, and the A wing portion is interposed between the stator member and the base, and the flow passage is located in the body.

Wherein, the thickness of the wing portion is smaller than the thickness of the body portion, avoiding excessively increasing the combined height of the stator member and the base, and allowing the flow passage to have a larger inner diameter without excessively increasing the overall In the case of height, the inner diameter of the flow path is greatly increased to increase the fluid flow rate and accelerate heat dissipation.
