Improving structure of rotor

Abstract

The invention relates to a rotor structure, which at least comprises rim and frame, wherein the rim has sealing end and open end; the outer face of sealing end has the first through hole; the inner face of sealing end has the second through hole; the first and second through hole are connected to form flow channel. The channel is inclining to accelerate flowing and avoid foreign materials into the first hole.

Description

technical field [0001] The invention relates to an improved structure of a fan rotor, in particular to a fan rotor structure that provides heat dissipation for the heat generated during the operation of the rotor. Background technique [0002] Please refer to FIG. 1 to FIG. 3 which shows the general fan rotor heat dissipation structure in the prior art. As shown in FIG. An open end 112 with a side wall 113 connected between the closed end 111 and the open end 112, and the closed end 111 is provided with at least one through hole 114, the inner wall of the through hole 114 is axially flat Straight, and the housing 12 is adjacent to the inner surface of the side wall 113, the housing 12 is provided with a top wall 121 adjacent to the closed end 111 of the hub 11, and the top wall 121 corresponds to the through hole 114 of the hub 11 There is a through-hole 122 with an inner wall that is axially straight, and an axis 13 is located in the top wall 121 of the housing 12; in addi...

AI Technical Summary

Problems solved by technology

[0003] Above-mentioned three kinds of prior art styles all are when wheel hub 11,21 and housing 12,22 are running, the fluid that is present in wheel hub 11,21 and housing 12,22 can flow from this through hole 114 and through hole 121 to Outflow, in order to reduce the fluid temperature in hub 11,21 and housing 12,22, but described prior art has its problem in implementation, when hub 11,21 and housing 12,22 rotate, The hub 11, 21 and the fluid in the housing 12, 22 follow the rotation to form a centrifugal flow, that is, the radial pressure of the fluid increases, and makes the housing 12, 22, the fluid density at the inner side increases, and when the fluid density is greater than the fluid density outside the through hole 114 and the through hole 121, the fluid flows through the through hole 114 and the through hole 121 to flow out, that is, the fluid due to radial pressure When the fluid passes through the through hole 114 and the through hole 121, the fluid needs to change the radial pressure into the axial direction because the inner wall is formed into the axially straight through hole 114 and the through hole 121. The pressure can pass through the through hole 114 and the through hole 121 and then flow out, so that the fluid forms an obstacle when it flows outward, and then the velocity of the fluid is reduced, that is, the heat convection efficiency is reduced, resulting in the inability to effectively display heat radiation

[0004] Furthermore, such as the fan rotor of U.S. Patent Application Publication No. 2004 / 0075356, the rotor assembly structure of the No. 566751 patent publication in Taiwan, China, and the self-cooling fan of the No. 568508 No. 568508, all of which are disclosed in the previous cases. In the technology, there are through holes on the hub or the casing, or on the hub and the casing to solve the heat generated by the motor rotor and the motor stator, but the inner wall of the through hole described in the technology is different from the above three existing ones. The through-holes of the technical structure are all axially straight, so it is impossible to effectively make the fluid flow out smoothly
