Oil bearing and its oil bearing fixed structure

The present invention provides an oil-impregnated bearing, and more particularly to an oil-impregnated bearing and an oil-impregnated bearing fixing structure thereof which can improve the support to reduce friction and reduce abnormal noise.

According to the advancement of the technological era, the operational efficiency of electronic components is becoming higher and higher, so that the requirements for the heat dissipation performance of the heat dissipation unit to the electronic components are also increased.
Taking a computer mainframe as an example, the internal central processing unit (CPU) generates a large amount of heat. In addition, when the central processing unit gradually increases in heat, the performance is reduced, and when the heat accumulation is higher than its allowable limit, Will force the computer to crash, in severe cases is more likely to cause damage; and, in order to solve the problem of electromagnetic radiation, usually the chassis is used to close the computer host, so that the central processing unit and other heating components (or The rapid export of the thermal energy of the component is an important issue.
Or large electronic devices such as general workstations or servers may generate high temperatures during operation. If the operating temperature exceeds a certain operating temperature, the high temperature may affect the performance of workstations, servers, etc., or even affect workstations and servers. The electronic components in the mainframe are burned and cause malfunctions, especially the data files or files stored in the workstation or the server are more important, so the short-term crash or damage will also cause subsequent losses, so the workstation When the server is erected, how to dissipate heat to maintain the temperature within the operating temperature range is a very important design step.
Therefore, the high-efficiency heat dissipating unit is one of the most important research and development priorities in the industry today, and the high-temperature electronic component is provided with a heat dissipating unit and dissipates heat to the electronic component through the heat dissipating unit, and the heat dissipating unit is usually The heat sink or the heat sink fins are equipped with a heat dissipating fan for heat dissipation work, and as the electronic device is developed in a small-volume manufacturing process, the thickness and thickness of the corresponding assembled heat-dissipating fan are also getting thinner and thinner.
