Abstract

The invention discloses a fan rotating speed measuring device applied to a server. The fan rotating speed measuring device includes a fan, a magnetic field generation unit, a current collection circuit and a data processing unit; the fan is arranged on server and is used for heat dissipation for server; blades of the fan are provided with inductors capable of cutting magnetic induction lines of anexisting magnetic field when the blades rotate. wherein the magnetic field generation part is used for generating a magnetic field to an area where blades of the fan are located, the current collection circuit is connected with the inductor and used for collecting current generated by the inductor when the blades of the fan rotate, and the data processing part is connected with the current collection circuit and used for calculating the rotating speed of the fan according to the current generated by the inductor. According to the fan rotating speed measuring device applied to the server, based on the electromagnetic induction principle, the fan blades rotate to generate electromagnetic induction current, the rotating speed of the fan is calculated according to the magnitude of the generated induction current, and the rotating speed of the fan can be accurately measured. The invention also discloses a server.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a fan speed measuring device applied to servers. The invention also relates to a server. Background technique [0002] In the current server design, the hard disks are arranged in a high density in the server, which leads to the increasingly limited internal space of the server, so the heat dissipation design of the server equipment becomes more and more important. At present, the mainstream heat dissipation solution is to install fans on the server equipment, and in order to ensure the heat dissipation effect, a tachometer will be set to measure the fan speed in real time. The basic management controller of the server will read the fan speed from the tachometer, and According to the temperature in the server, the speed of the fan is controlled in real time, so as to ensure the heat dissipation effect in the server and keep the temperature of the server within a safe range.
