[0023] See also Figure 1-3 The present invention provides an embodiment of a cooling fan speed performance test bench, comprising a test table 1, wherein the test table 1 is made of an aluminum alloy plate. The structural design of the aluminum alloy plate ensures that the test bench of the present invention has good structural strength while having a light weight, thereby conveniently reducing the overall weight and improving the portability.

[0024] A trough is provided at the front end of the test table 1. A grid plate 2 is fixedly installed in the trough at the front end of the test table 1. The grid plate 2 can ensure normal ventilation effect. A control panel 3 is provided at the rear end of the test table 1. Two sets of interface circuit boards 4 are fixedly installed on the control panel 3. The interface circuit boards 4 are provided with several different types of fan interfaces. By providing different fan interfaces, the performance of fans with different interfaces can be tested, thereby improving the adaptability of fan testing and reducing usage limitations.

[0025] A switch button 8 is provided on one side of the interface circuit board 4, and a voltage adjustment knob is provided below the switch button 8. A lower control box 5 is fixedly installed on the lower surface of the test table 1 just below the control panel 3;

[0026] Furthermore, a control circuit board is fixedly installed inside the lower control box 5, on which a control single chip microcomputer and a voltage regulator are installed. The control circuit board is electrically connected to the interface circuit board 4, the switch button 8 and the voltage adjustment knob (not shown in the figure, not marked, refer to the appendix of the manual for details) through a data wire. Figure 1 shown);

[0027] Among them, a connection wire 7 is fixedly installed on the front outer wall of the lower control box 5. The connection wire 7 is electrically connected to the control circuit board. The other end of the connection wire 7 is provided with a connector for connecting to a computer (not shown in the figure), so that the utility model can be powered on and work online through the connection wire 7;

[0028] According to the above description, in actual use, the end of the connecting wire 7 of the utility model with the connector can be plugged into the computer used for detection. At this time, the connector of the cooling fan is inserted into the adapter interface of the interface circuit board 4, so that the cooling fan is detected and powered on through the interface circuit board 4;

[0029] During the test, the voltage adjustment knob can be manually rotated. The voltage adjustment knob can be used to adjust the output voltage of the cooling fan in conjunction with the voltage regulator. In this way, the fan speed under different output voltages can be tested to achieve the purpose of speed performance testing of the fan at different voltages, so as to determine whether the fan speed meets the standard under different voltages.

[0030] The cooling fan speed performance test bench of this utility model can extremely conveniently complete the purpose of detecting whether the fan speed performance meets the standard under different voltages. It has a good fan speed performance detection effect. At the same time, it is equipped with different types of fan interfaces, so it can be used for performance detection of different types of cooling fans. It is easy to use, has strong product applicability, and effectively reduces usage limitations.

[0031] In this embodiment, in order to ensure normal heat dissipation of the circuit board structure inside the lower control box 5, a number of heat dissipation slots 6 with equal spacing and linear distribution are opened on the outer walls on both sides of the front side of the lower control box 5.

[0032] In this embodiment, strip-shaped slide grooves 9 are provided on both sides of the grid plate 2 and on the outer wall of the test table 1, and a sliding seat 10 is slidably connected in the two strip-shaped slide grooves 9;

[0033] Among them, the two sliding seats 10 are fixedly mounted with upper vertical plates 11, and a horizontal connecting plate 12 is fixedly mounted between the two upper vertical plates 11;

[0034] Furthermore, in order to facilitate the fixing and bonding of the fan that needs to be tested for performance, an adhesive plate 13 is adhered to the cross-connecting plate 12 by glue, and the adhesive plate 13 is made of adhesive silicone;

[0035] With this structural design, the cooling fan that needs to be tested for performance can be placed directly on the adhesive plate 13. The adhesive plate 13 can be used to slightly glue the bottom of the cooling fan, thereby achieving a fixing effect during fan testing and improving the stability of the cooling fan during operation. At the same time, it is convenient to take out and can be directly unplugged, which is convenient to use.

[0036] Moreover, the adhesive plate 13 can be moved up and down along the strip slide groove 9 driven by the sliding seat 10, so that the distance between the adhesive plate 13 and the interface circuit board 4 can be adjusted, so that it can be used for cooling fans with wire harnesses of different lengths, avoiding the disadvantage of the cooling fan wire harness being too short to be plugged into the interface, and improving the overall use effect.

[0037] In this embodiment, in order to ensure the horizontality of the bottom of the test bench of the utility model and facilitate the placement and use of the desktop, please refer to the attached manual for details. Figure 2 As shown, a pad strip 14 is fixedly installed on the lower surface of the front end of the test table 1, and the lower surface of the bottom end of the pad strip 14 is in the same horizontal plane as the lower surface of the lower control box 5.

[0038] Working principle: When the utility model is in use, the test bench can be placed directly on a horizontal table. At the same time, the end of the connecting wire 7 of the utility model with the connector can be plugged into the computer used for testing, so as to facilitate the later performance testing of the fan through the computer's testing software;

[0039] Then, the cooling fan that needs to be tested for speed is pressed onto the adhesive plate 13. The adhesive plate 13 can be used to slightly adhere the bottom of the cooling fan, thereby achieving a fixing effect during fan testing and improving the stability of the cooling fan during operation. At the same time, it is convenient to take out and can be directly unplugged when taking it out, which is convenient to use.

[0040] At this time, the connector of the cooling fan is inserted into the adapter interface of the interface circuit board 4 , so that the cooling fan is detected and powered on through the interface circuit board 4 .

[0041] During the test, the voltage adjustment knob can be manually rotated, and the voltage adjustment knob can be used to adjust the output voltage of the cooling fan by cooperating with the voltage regulator. Different output voltages will result in different fan speeds. The test data can be transmitted to the test computer through the connecting wire 7, so that the test value can be displayed by the test software of the computer;

[0042] In this way, the fan speed under different output voltages can be tested, so as to achieve the purpose of testing the fan speed performance under different voltages, thereby judging whether the fan speed under different voltages meets the standard.

[0043] The cooling fan speed performance test bench of this utility model can easily complete the purpose of testing whether the fan speed performance meets the standard under different voltages, and has a good fan speed performance testing effect. At the same time, by being equipped with different types of fan interfaces, it can be applied to different types of cooling fans for performance testing. It is easy to use, has strong product applicability, and effectively reduces usage limitations.

[0044] At the same time, the utility model can be directly placed on the desktop for use, has a compact structure, does not need to occupy ground area, has low manufacturing and maintenance costs, effectively reduces the purchase and maintenance costs of enterprises, and reduces the economic burden of production enterprises. It is easy to use, has a light overall weight, is easy to pick up and carry, has a good use effect, and is more practical.
