Multi-duct exhaust system

Abstract

The invention relates to a multi-duct exhaust system provided with four exhaust fans. The back of each exhaust fan is connected with a single duct which is formed by encircling a semilunar protective plate, a clipboard and a wind chamber hood, the ducts of two exhaust fans at the same height are combined at the terminal of the clipboard into a wind chamber, wind chambers at different heights are arranged up and down, the lower wind chamber is parallel to the upper wind chamber through a step wind chamber at the back of the upper wind chamber and connected with a wind-collecting chamber which is provided with a flexible connecting duct, either exhaust fan is a centrifugal exhaust fan, a temperature control module is arranged on the outer wall of the step wind chamber, provided with an LED display panel and an alarm, and electrically connected with the exhaust fan, and the system is provided with a mounting door panel and a door panel frame with both locks at two sides so as to be unlocked left or right. The multi-duct exhaust system has small thickness and size and is mounted at the back of a cabinet to realize zero space occupation, and the plurality of exhaust fans can provide an upper limit of enough exhaust and provide various exhaust flow selections.

Description

technical field [0001] The invention relates to an exhaust device for a cabinet of a communication machine room, in particular to a multi-air channel exhaust system. Background technique [0002] In the communication room, the exhaust heat dissipation of the cabinet is a very important link. A high-density computer room environment can cause IT equipment to overheat and cause downtime. In order to ensure the uniform temperature inside the cabinet, prevent the recirculation of hot air discharged from the equipment, and eliminate hot spots in the equipment room. To ensure the normal operation of high-density server equipment, the design of the cabinet exhaust system can extract the waste heat inside the cabinet and send the hot air to the air collection chamber, while allowing the cold air to freely enter the cabinet, thereby solving the problem of improper wind transmission inside the cabinet. [0003] If there is not enough exhaust heat dissipation, the working temperature...

AI Technical Summary

Problems solved by technology

[0003] If there is not enough exhaust heat dissipation, the working temperature in the cabinet is too high, which will cause the equipment to malfunction or even crash

If the exhaust flow rate is large, the volume must be large; if the volume is small, it is easy to have the problem of not being able to exhaust and dissipate heat in time
