Description

Core flow channel structure

The present invention relates to motors, and more particularly to a flow path configuration for an iron core.

Traditionally, when the motor is in operation, most of the heat generated by the high-speed operation of the rotor accumulates inside the motor casing. In addition to making the carbon brush easy to deposit carbon and affecting the flow of current, the magnetic force provided by the magnet is also easily lowered, which affects the motor. Output performance.

Inspect, the heat dissipation method of the iron core of the conventional core is attached to the outer side or the upper and lower sides of the stator or the rotor in the form of a cooling fin, or the cooling fin is combined with the flow passage to be disposed on one side of the iron core, thereby suppressing iron. The heat generated by the operation of the core; however, most of the heat generated by the operation of the motor is accumulated inside the motor casing, and the conventional flow path is provided on the base of the cooling fin or the cooling fin and the iron core. Rather than the construction of the core itself, it is not possible to achieve the heat dissipation of the heat generated inside the auxiliary motor, so it is still not the technical content.

Accordingly, it is a primary object of the present invention to provide a flow path structure for a core that can form a passage through which fluid can pass, thereby enabling the fluid to pass through the motor core to achieve the effect of cooling the motor to enhance motor operation. efficacy.

In order to achieve the above object, the flow path structure of the iron core provided by the present invention comprises a body portion, a sleeve portion that is sleeved with the body portion, and a spacer portion disposed on the body portion. Between the body and the sleeve portion, a gap space is formed between the body portion and the sleeve portion for fluid to flow, thereby reducing thermal energy generated during operation of the iron core.

Wherein, the body further has a plurality of first sheets and a plurality of second sheets which are overlapped with each other, and more specifically, a structure for forming an iron core, each of the first sheets and each of the second sheets The system is annular and coaxially bonded to each other, allowing eddy currents to pass through a smaller cross section to reduce eddy current losses.

Furthermore, in order for the spacer to form the space between the body and the sleeve for fluid flow, the spacer further has a plurality of first spacers and a plurality of second spacers, and each of the spacers The first spacer is disposed on each of the first sheets, and extends along the annular peripheral surface of each of the first sheets to form a first arc length; each of the second spacers is disposed in each of the second Forming a second arc length on the sheet body and extending along the annular circumferential surface of each of the second sheets, and making the first arc length and the second arc length unequal, and simultaneously making each of the first The spacer is interlaced with each of the second spacers in a stepped manner, so that the gap space between each of the first spacers and each of the second spacers forms a spiral passage for fluids The first sheet flows between each of the second sheets.

In addition, the sleeve portion can be sleeved on the outer side of the body portion, and each of the first spacer body and each of the second spacer body can be disposed outside each of the first sheet body and each of the second sheet bodies. a torus, according to which the spiral passage is provided around the outer side of the body; and vice versa, the sleeve can be worn over the inner side of the body, and the first spacer and each of the first spacers The second spacer body may also be disposed on the inner annular surface of each of the first sheet body and each of the second sheet bodies, so that the spiral passage is disposed on the inner side of the body portion, and has reached the same core. The effect of heat dissipation.

First, referring to the first to third figures, the flow path structure (10) of the iron core according to the first preferred embodiment of the present invention mainly includes a body portion (20) and a body. a sleeve (30) and a spacer (40), wherein:

The body (20) has a cylindrical shape.

The sleeve (30) is threaded over the outer side of the body.

The spacer (40) is protruded from the body.

Specifically, in order to form the body portion (20) into a core structure, the body portion (20) further has a plurality of first sheets (21) and a plurality of second sheets (22) in a ring shape. And overlap each other in a coaxial manner.

In order to make the spacer (40) between the body (20) and the sleeve (30), a gap space (41) for fluid flow is formed, and the spacer (40) is more toothed. a plurality of the first spacers (42) are fixed to the outer surface of each of the first sheets (21), and the second spacers (43) having a plurality of teeth are fixed to the respective ones. The outer faces of the two sheets (22) are arranged in a staggered manner with each of the first spacers (42) and the second spacers (43), and more specifically The body (20) is formed in a stepped structure, and each of the first spacers (42) extends along the outer side of each of the first sheets (21) by a first arc length (44), each of the second intervals. The body (43) extends along the outer side of each of the second body (22) with a second arc length (45), and the length of the first arc length (44) is a superior arc, and the second arc length The length of (45) is a bad arc, so that each of the first spacers (42) and each of the second spacers (43) is caused by each of the first sheets (21) and the second sheets (22). The difference in the length of the extended arc, so that the body (20) forms a stepped structure, and the cylindrical periphery of the body (20) Between sleeve portion (30) forming the gap space of the spiral (41), through which the fluid core.

In the implementation, as shown in the third figure, the body (20) is formed by stacking a plurality of the first body (21) of the steel material and the second body (22). The sleeve system is sleeved on the outer side of the body (20), but the majority of the first body (21) and the majority of the second body (22) are not limited to the steel material, and at the same time, the spiral is formed. The gap space (41), the stacking manner of the plurality of first sheets (21) and the plurality of second sheets (22) may be a single sheet or a plurality of the first sheets (21) and a single sheet The sheet or a plurality of the second sheets (22) are alternately stacked to allow fluid to pass through the gap space (41) to reduce the heat generated by the operation of the core and improve the running efficiency of the motor.

Furthermore, the spacer (40) may also have a different arrangement from the above embodiment. Specifically, please refer to the fourth to sixth embodiments, in the second preferred embodiment of the present invention. In the provided core structure (10a), the plurality of first spacers (42a) and the plurality of second spacers (43a) are provided in each of the first sheets except for the above embodiment. And (21a) and the outer surface of each of the second sheets (22a), or the inner surface of each of the first sheets (21a) and the second sheets (22a), and Each of the first body (21a) and each of the second body (22a) forms the spiral gap space (41a), and the sleeve portion (30a) is sleeved in the body (20a). The gap between the body (20a) and the gap space (41a) for fluid flow is formed to achieve the same effect of reducing the heat energy generated by the iron core during operation of the motor.
