Fluid cooling mechanism for rod motor

This creation is related to electric motors, in particular to a fluid cooling mechanism for a rod motor.

In the case of a conventional rod motor, it is generally based on a rod stator of a suitable length such that a tubular mover is coaxially threaded over the stator, and the inside of the mover can be used. The change in the magnetic field generated by the coil interacts with the magnetic field on the stator to drive the mover to reciprocate along the axial direction of the stator.

Since the change of the internal magnetic field of the mover is caused by the introduction of the current, the electric energy is generated by the coil while the heat is generated. Therefore, in order to allow the heat to be properly dissipated, the motor is prevented from affecting the operation. The efficiency of the work, in the new patent No. M366831 in China, reveals a kind of rod motor motor radiator cooling device, which is provided with a plurality of heat dissipation channels between the mover shell and the mover coil, so that the heat generated by the electric energy can be generated. Dissipating outward through the heat dissipation channels.

Further, the pre-opening of the new patent will set the heat dissipation channel between the mover housing and the coil to improve the heat dissipation surface area, which can improve the heat dissipation effect, but the technology can only be located away from the stator outside the stator. The heat is guided by the air, but the heat dissipation effect that the mover can provide adjacent to the inner side of the stator is obviously poor. The air gap between the sub-tooth is usually very narrow, so that when the mover moves back and forth on the stator, the turbulence is very significant because the air gap entrance is too narrow, so that it cannot be introduced by external air. In this way, the airflow in the air gap is smoothly flowed, and it is difficult to achieve better heat dissipation.

Therefore, the main object of the present invention is to provide a fluid cooling mechanism for a rod motor which is formed in a planar abutting state between a mover and a stator, on which a flat-plate cooling mechanism is disposed, by means of a fluid The continuous flow dissipates heat energy and achieves the cooling effect of heat dissipation.

Therefore, in order to achieve the above object, the fluid cooling mechanism of the rod motor provided by the present invention comprises a continuous rod-shaped stator member; a tubular moving member is slidably disposed on the stator member. And reciprocally displaced along the axial direction of the stator member, having two annular end portions, a plurality of annular coils are sequentially arranged coaxially between the two end portions, and a mover housing is wrapped around the coils The outer side is located between the two end portions; at least one cooling portion is disposed on the movable member, and has a heat dissipation flow path for allowing external fluid to flow in the heat dissipation flow path, a flow path and an outflow path And communicating with the heat dissipation channel respectively, wherein the external fluid flows from the inlet channel into the heat dissipation channel and flows out through the outlet channel; and the feature is that the mover is The member has a bearing plane formed by a part of each of the inner inner annular faces of the coil; the cooling portion has a plate-like body attached to the receiving plane and interposed therebetween Between the coil and the stator member, and the heat dissipation flow path is located in the body.

Further, the heat dissipation channel is formed by the body having a first plate and a second plate stacked on each other, and the heat dissipation flow path is interposed between the first plate and the second plate. Between.

In addition, in order to ensure the insulation between the body and the moving member, an insulating layer made of a suitable insulating material may be interposed between the body and the receiving plane.

Furthermore, in order to improve the efficiency of heat dissipation, the number of the cooling portions may be two or more, and the number of the bearing planes is corresponding to the number of the cooling portions. Set up.

Wherein, in order to appropriately form each of the bearing planes, each of the coils may be a polygon of the same shape.
