Embodiment Construction

[0034] The core idea of ​​the present invention is: acquire the temperature of the electronic equipment, and control and manage the working state of the ventilation device in the electronic equipment according to the acquired temperature and the predetermined critical control temperature in the electronic equipment.

[0035] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0036] When a fire occurs, if there is sufficient oxygen in the place where the fire starts, the fire will spread rapidly; on the contrary, if the fire is isolated from oxygen, the fire will be quickly brought under control. The present invention is based on this most common, the most effective fire extinguishing principle just.

[0037] Generally, the casings of electronic equipment are closed, and the electronic equipment is provided with ventilation devices such as fans for reasons such as heat dissipation. The ve...

Abstract

The present invention is ventilator managing method and device for electronic equipment and has the kernel of controlling the work state of the ventilator in electronic equipment based on the temperature inside the electronic equipment. The present invention has double layer of control and management on the ventilator in electronic equipment, and can avoid the negative effect of ventilator in case of some fire inside the electronic equipment and thus can decrease loss caused by fire. The present invention is simple and low in cost, may be used widely in various kinds of electronic equipment, and has no influence on the reliability of electronic equipment.

Description

technical field [0001] The invention relates to electronic equipment, in particular to a management method and device for a ventilation device in the electronic equipment. Background technique [0002] In human production and life, the occurrence of fire is inevitable. [0003] With the development of science and technology, the application of electronic equipment has been popularized in people's daily production and life. Fires caused by electronic equipment are common occurrences. Especially in a large central computer room such as a communication system, once an electronic device catches fire, the heat dissipation device in the electronic device will cause the fire to spread, causing very serious consequences. How to minimize the loss of electronic equipment after it catches fire has become an urgent problem to be solved. [0004] For this problem, the industry has begun to pay attention to this problem. For example, a new FIRE TEST (fire test) has been added to the NE...
