Problems solved by technology

However, in practical applications, a disadvantage of this static correspondence fan speed control method is that circuit design engineers need to spend more time and energy to calculate the required temperature-to-speed correspondence table, so it is less suitable for human resources. cost-effective application
In addition, the fixed speed response method cannot cope with extreme overheating conditions, so it is easy to cause the internal circuits of the blade server to be burned under such conditions

Abstract

A dynamic controlling type heat dissipating method and system of electronic equipment can be used for being matched with a piece of electronic equipment such as a blade server, a desktop personal computer or a laptop to provide a dynamic controlling type heat dissipating function. The invention is characterized in that the operating temperature range of the electronic equipment is divided into two stages: a linear stage and a high temperature stage. When in the linear stage, a linear way is used for corresponding to a fan speed value; on the contrary, when in the high temperature stage, a dynamic controlling way is used for controlling the fan rotational speed to reduce the temperature to the linear stage rapidly.

Description

technical field [0001] The invention relates to a heat dissipation technology for electronic equipment, in particular to a dynamic control type heat dissipation method and system for electronic equipment. Background technique [0002] Electronic devices often generate heat due to power consumption during operation. If the heat is not removed, the circuit elements or chips in the electronic equipment may be burned and cause a destructive shutdown. A general solution to this problem is to install a cooling device, such as a fan device, in the body frame of the electronic device, so as to remove the heat generated by the electronic device during operation. For example, one or more fan devices are usually arranged in the body frame of a blade server or a desktop personal computer to use wind force to blow off the heat generated during operation, thereby protecting its internal host circuit from Burned due to excessive temperature. [0003] In practice, the activation of the f...
