Description

server enclosure

The present invention relates to a server casing, in particular to a server casing including a damper.

Generally speaking, in order to effectively dissipate the heat generated by the electronic components in the server, a fan is provided in the server casing. Moreover, in order to facilitate disassembly and assembly of the fan from the server casing, the fan is arranged on the server casing through the fan frame. Since the vibration generated by the fan during operation is often transmitted to the storage device of the server through the server case and affects the performance of the storage device, the fan frame is installed on the server machine through deformable vibration isolators such as sponges or gaskets. shell.

However, since the fans of different servers have different specifications, the fans transmit vibrations to the storage devices in different ways. Therefore, it is necessary to design dedicated vibration isolators for different servers to effectively prevent the transmission of vibrations generated by the fans. to the storage device. That is to say, the traditional vibration isolators cannot be shared for the fan frame carrying the fans of different specifications, which will increase the overall manufacturing cost of the server. In addition, traditional vibration isolators not only easily affect the circuit design of the main board of the server, but also affect the flow channel design of the fan.

The present invention is to provide a server casing, the fan frame of which is arranged on the casing body through a damper as a magneto-rheological fluid damper, so that the damper can effectively prevent the fan frame from transmitting the vibration generated by fans of any specification to another location on the server enclosure.

A server casing disclosed in an embodiment of the present invention includes a casing body, at least one damper and a fan frame. At least one damper is fixed on the casing body. The fan frame is disposed on the casing body through at least one damper. At least one damper is a magnetorheological fluid damper.

According to the server casing disclosed in the above embodiments, the fan frame is disposed on the casing body through the damper and the damper is a magneto-rheological fluid damper. Therefore, when the damper assists the fan frame carrying fans of different specifications to be installed on the case body, the magnetic field in the damper will change according to the amplitude of the vibration generated by the fan mounted on the fan frame, thereby changing the vibration in the damper. The apparent viscosity of magnetorheological fluid. In this way, the damper can use the magnetorheological fluid with a higher apparent viscosity to absorb vibrations with a larger amplitude, and use the magnetorheological fluid with a lower apparent viscosity to absorb vibrations with a smaller amplitude, so that the damper can Effectively prevent the fan frame from transmitting the vibration generated by fans of any specification to other positions of the server casing.

The detailed features and advantages of the embodiments of the present invention are described in detail below in the implementation modes, the content is enough for anyone with ordinary knowledge in the field to understand the technical content of the embodiments of the present invention and implement them accordingly, and according to the disclosure of this specification Anyone with ordinary knowledge in the art can easily understand the related objectives and advantages of the present invention.
