Abstract

The invention provides an air quantity measuring device of a computer fan, which comprises an air guide sleeve and a stating ring, wherein, the centers of the air guide sleeve and the stating ring are both provided with a portiforium correspondingly; the stating ring is provided with at least one hot wire airspeed probe; a probing end of the hot wire airspeed probe is extended into the portiforium of the stating ring; the air guide sleeve tightly fits the stating ring. A measuring bench of the computer fan can be placed at the outlet of a computer system fan, the air guide sleeve is used to lead the air exhaust of the system fan to pass through the hot wire airspeed probe, the air quantity of the computer fan can be received by matching with an airspeed measuring device, thereby facilitating the performance evaluation of the computer fan.

Description

technical field [0001] The invention relates to an air flow measuring device, in particular to a computer fan air flow measuring device. Background technique [0002] Nowadays, computers have been widely used in various fields such as people's life, work and study, and their importance is self-evident. As we all know, high temperature is a very critical factor affecting the stability of computers, especially for computers with high frequency equipment, heat dissipation is particularly important in summer. [0003] After the current system fan is fixed in the computer, the working status of the system fan in the computer system cannot be known, that is, the air volume of the system fan during operation cannot be known, which is not conducive to evaluating the working efficiency of the system fan. Contents of the invention [0004] In view of the above, it is necessary to provide a computer fan air volume measuring device to facilitate the measurement of the computer fan ai...
