Applied to the combination structure of laser connecting metal parts and shafts in fans

Abstract

The invention relates to a combining structure applied to a fan and used for connecting a metal piece with an axle center by laser. The combining structure comprises the metal piece and the axle center, wherein an open hole, a first side and a second side are formed in the metal piece; the axle center is inserted into the open hole which penetrates through the center of the metal piece; at least one first fusion welding part is formed between the outer circumferential side of the axle center and the contact position relative to the first side, and the first fusion welding part is connected with the outer circumferential side of the axle center and the first side adjacent to the open hole, so that the metal piece and the axle center are combined into a whole; the combining structure is applied to the fan, so that the effect of cost reducing is effectively achieved.

Description

technical field [0001] The present invention relates to a combined structure, especially an application that can save costs and increase the balance of the fan, and can also be applied to fans with small or large torque to achieve the effect that the shaft center is not easy to loosen. In the fan, the laser is used to connect the metal parts and the combined structure of the shaft. Background technique [0002] By the way, as the computing performance of electronic equipment increases day by day, the electronic components installed inside it will generate a lot of heat during operation. It is usually necessary to install radiators or cooling fins on the electronic components to increase the heat dissipation area and improve the heat dissipation effect. However, the heat dissipation The heat sink and heat dissipation fins only dissipate heat through radiation, and the heat dissipation effect achieved is limited. Therefore, an additional cooling fan with improved heat dissipat...

AI Technical Summary

Problems solved by technology

[0008] 1. The thermal deformation resistance and structural strength of the integrated fan wheel are not good, so that it is easy to cause the shaft center to be skewed and the fan wheel to be deformed, so that it cannot be applied to the cooling fan with large torque;

[0009] 2. The overall cost of the fan wheel combined with stamping is increased, and the concentricity is difficult to control;

[0010] 3. The unbalance of the fan wheel is large;
