In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.
[0019] In the description of the utility model, it is necessary to explain that, unless otherwise explicitly specified and limited, the terms "mounting", "provided with", "connection" and the like should be broadly understood, for example, "connection" can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0020] Please refer to Figs. 1-3 The utility model provides an embodiment: a kind of video card heat dissipation module performance test equipment, including lower bottom plate 1, lower bottom plate 1 upper surface fixed mounting has electrical element box 2, electrical element box 2 is used to the built-in installation of the operating electrical element of the equipment, wherein, the outer wall of electrical element box 2 side is open type structure design, electrical element box 2 inside fixed mounting has control element 12, control element 12 is controller and the like electrical element;
[0021] Electrical element box 2 upper surface fixed mounting has upper supporting plate 3, fan slot 13 is set in the center position of the outer surface of upper supporting plate 3, and the heat dissipation fan needing to be tested can be installed and placed by the fan slot 13 set;
[0022] Upper supporting plate 3 upper surface four corners are all fixed mounting and have upper stand 4, and four upper stands 4 top are fixed mounting and have fixed top plate 5, and fixed top plate 5 upper surface center position fixed mounting has cylinder mounting plate 6, and cylinder mounting plate 6 upper surface is fixed mounting and has drive cylinder 7 by bolt, and the output end of drive cylinder 7 telescopic activity is connected with air pressure rod 8, and the bottom of air pressure rod 8 is fixed mounting and has lower lifting seat 9, and lower lifting seat 9 lower surface fixed mounting has mounting seat 10, and mounting seat 10 lower surface center position fixed mounting has wind speed sensor 11, wherein, wind speed sensor 11 is ultrasonic wind speed sensor;
[0023] Ultrasonic wind speed sensors are existing technology products. Their working principle is as follows: air flows through the sensor probe measurement area, where two pairs of ultrasonic probes (usually arranged in a cross shape) are placed. By calculating the time difference of ultrasonic wave transmission between the two points, the wind speed can be calculated, thereby achieving the purpose of measuring wind speed.
[0024] Based on the above structure, when it is necessary to test the performance of the cooling fan speed change at different distances, this utility model provides a fan slot 13 on the upper support plate 3. The cooling fan used for performance testing can be placed and installed through the fan slot 13, and the cooling fan is powered.
[0025] At this time, the powered cooling fan can rotate and blow air. The air circulation effect caused by the blow can be sensed and detected by an ultrasonic wind speed sensor, so that the working curve of the cooling fan wind speed at the current height can be measured.
[0026] This utility model incorporates a drive cylinder 7, which drives a pneumatic rod 8 to extend and retract. When the pneumatic rod 8 extends or retracts, it causes the lower lifting seat 9 at the bottom to move up and down. Simultaneously, the lower lifting seat 9 moves up and down, causing the wind speed sensor 11 to shift vertically. This changes the distance between the wind speed sensor 11 and the cooling fan. By detecting the wind speed at different distances, wind speed spline curves can be obtained. The obtained spline curve data can then be used to determine the cooling fan's impact on the heat-generating components at different distances. This invention provides a convenient way to dynamically test the performance of the graphics card cooling module fan at different distances.
[0027] In this embodiment, in order to improve the guiding performance and accuracy of the displacement of the lower lifting seat 9, the four corners of the lower lifting seat 9 are respectively fitted onto the outside of the four upper columns 4, and the lower lifting seat 9 is slidably connected to the upper columns 4.
[0028] Working principle: When it is necessary to test the performance of the cooling fan by measuring the wind speed change at different distances, this utility model provides a fan slot 13 on the upper support plate 3. The cooling fan used for performance testing can be placed and installed through the fan slot 13, and the cooling fan is powered.
[0029] At this time, the powered cooling fan can rotate and blow air. The air circulation effect caused by the blow can be sensed and detected by an ultrasonic wind speed sensor, so that the working curve of the cooling fan wind speed at the current height can be measured.
[0030] This utility model incorporates a drive cylinder 7, which drives a pneumatic rod 8 to extend and retract. When the pneumatic rod 8 extends or retracts, it drives the lower lifting seat 9 at the bottom to move up and down. As the lower lifting seat 9 moves up and down, it simultaneously drives the wind speed sensor 11 to move up and down, thereby changing the distance between the wind speed sensor 11 and the cooling fan. By detecting the wind speed at different distances, wind speed spline curves can be obtained at different distances. The obtained spline curve data can be used to determine the cooling effect of the cooling fan on the heat dissipation of the heat-generating components at different distances. This invention provides a convenient way to dynamically test the working performance of the graphics card cooling module fan at different distances.
[0031] Meanwhile, the wind speed measured by the wind speed sensor 11 can be used to calculate the wind pressure value at that distance using a formula, thereby obtaining the wind pressure data of the fan at that distance. The calculation formula is Q = 60AV, where Q is the flow rate, A is the flow area, and V is the average flow velocity.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
