Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spindle motor heat dissipation, in particular to a cooling structure of a spindle motor. Background Art
[0002] The original meaning of textile is a general term for spinning and weaving. However, with the continuous development and improvement of the textile knowledge system and discipline system, especially the emergence of non-woven textile materials and three-dimensional composite weaving technologies, it is no longer just traditional hand-spinning and weaving, but also includes non-woven technology, modern three-dimensional weaving technology, modern electrostatic nano-netting technology, etc., which produce clothing, industrial, and decorative textiles. In the production process of clothing textiles and industrial textiles, spindle motors such as direct twisting machines and double twisting machines are required to drive the operation of textile devices. Due to the special structure of direct twisting machines and double twisting machines, spindle motors such as direct twisting machines and double twisting machines cannot be equipped with cooling fans like ordinary motors. During the working process, a cooling system is required to protect the motors.
[0003] When the spindle motor runs at high load or high power density, the motor temperature is high, and the motor components need to be reasonably cooled. However, the heat dissipation of the direct twisting machine and the two-for-one twisting machine on the market has always been a problem to be solved. Usually, the heat dissipation ribs are evenly distributed on the outer periphery of the shell, and each device needs to be equipped with a 7.5Kw exhaust system separately, but the heat dissipation effect is not obvious, resulting in a relatively high temperature inside the motor, reaching 60°C, and the bearings are easily burned after long-term operation, and the service life of the internal components is relatively short. At the same time, the fan takes up space, and it will also cause the direct twisting machine and the two-for-one twisting machine to have high noise, large loss, low energy efficiency, and the overall temperature of the production workshop to rise, which makes the operators feel uncomfortable.

[0005] In order to solve the above technical problems, an embodiment of the utility model provides a cooling structure of a spindle motor, wherein a front end cover and a rear end cover are respectively provided at both ends of the motor, and the cooling structure includes a cover and a cooling pipe. The cover is clamped between the front end cover and the rear end cover, and a channel is provided in the cover. The cooling pipe is distributed in the channel in a U-shape and is attached to the inner wall of the cover.
[0006] Furthermore, the cover includes an inner cover and an outer cover, the shape of the inner cover is adapted to the shape of the outer wall of the spindle motor, the gap between the inner cover and the outer cover forms the channel, and the cooling pipe is attached to the inner wall of the outer cover.
[0007] Furthermore, the cover is in a fan-shaped structure and surrounds the circumference of the spindle motor.
[0008] Furthermore, the cover is interference fit with the front end cover and the rear end cover.
[0009] Furthermore, the cover is made of aluminum material, and the cooling pipe is made of copper material.
