this paper relates to an air volume measuring device, in particular to a computer cooling fan air volume measuring device.

after the current system cooling fan is fixed in the computer, the working state of the system cooling fan in the computer system cannot be known, that is, the air volume of the system cooling fan in the running process cannot be known, which is not conducive to evaluating the I performance of the system fan.

in view of the above, it is necessary to provide a computer cooling fan air volume measuring device, in order to facilitate the measurement of computer cooling fan air volume. The invention relates to an air volume measuring device for a computer heat dissipation fan, which comprises a guide cover and a fixing ring, wherein the centers of the guide cover and the fixing ring correspond to is provided with an opening, the fixing ring is also provided with at least one hot wire wind speed probe, the detection end of the hot wire wind speed probe extends into the opening of the fixing ring, and the flow guide cover is tightly matched with the fixing ring.

a hot-wire wind speed probe, the detection end of which extends into the opening of the fixing ring.

the above-mentioned computer cooling fan measuring rack can be placed at the outlet of the computer system fan, and the system cooling fan can be exhausted through the hot-wire wind speed probe by using the air guide cover, and the air volume of the computer cooling fan can be measured by matching with the wind speed measuring instrument, which is convenient for evaluating the efficiency of the computer cooling fan.

the following is a further detailed description of the present invention with reference to the accompanying drawings and preferred embodiments.

fig.I is a perspective exploded view of the preferred embodiment of the computer cooling fan wind profile measuring device.

fig.2 is a perspective assembly view of the preferred embodiment of the air volume measuring device of the computer cooling fan.

detailed description

are correspondingly provided with a circular opening.

the base frame 12 comprises a square main body 122, a support rod 124 extending vertically downward from one end of the main body 122 and a support frame 126, wherein the support frame 126 comprises a circular chassis 129, a hollow rod 128 extending vertically upward from the chassis 129 and a hollow rod 128 arranged at the an adjusting screw 127 on the side of the hollow rod body 128.the support rod 124 can be inserted into the hollow rod body 128, and its extension degree is controlled by the adjusting screw 127.

one side of the fairing 14 and the fixing ring 16 is respectively provided with a matching part 142 and 162, two sides of the main body 122 of the base frame 12 are respectively provided with two accommodating parts 123 corresponding to the matching parts 142 and 162, and the matching parts 142 and 162 are tightly matched with the accommodating parts 123, so that the the guide cover 14, the fixing ring 16 and the main body 122 mounted on the base frame 12.

the fixing ring 16 is provided with three hot-wire wind speed probes 164, the hot-wire wind speed probes 164 are uniformly distributed on the fixing ring 16 and their detection ends are respectively extended into the openings of the fixing ring 16, and the side surfaces of the fixing ring 16 are provided with there are three fastening screws 166, which are used to fix the hot wire wind speed probe 164.

during air volume measurement, only the air guide cover 14 of the computer fan air volume measuring device 10 needs to be aligned with the outlet of a computer fan, so that the system fan exhausts air through the hot wire wind speed probe 164, and the average wind speed of the computer fan can be obtained through calculation after the numerical value, thus obtaining the air volume of the computer fan.

with continued reference to fig.3, in another preferred embodiment herein, a computer fan air volume measuring device 20 includes the circular guide cover 14 and the circular fixing ring 16, one side of the guide cover 14 is provided with a fitting part, and one side of the fixing ring 16 corresponds to the fitting part is provided with an accommodating part, the matching part and the accommodating part are tightly matched, a magnetic material coating is arranged on the other side of the flow guide cover 14, and the flow guide cover 14 can be adsorbed at the outlet of the computer fan, thereby respectively measuring the hot wire wind speed the value on the probe 164 can obtain the average wind speed of the computer fan, thus obtaining the air volume of the computer fan.
