This week, our factory conducted a series of standardized tests in the wind tunnel laboratory, focusing on the performance of our high-pressure fan when integrated with a radiator into a complete cooling module. The tests evaluated heat dissipation performance at different fan speeds, as well as the stability of the fan under CAN control.
To measure the module’s cooling efficiency under various working conditions, we tested the system at different duty cycles (fan speeds). We recorded key parameters including ambient temperature, water inlet/outlet temperature, water flow rate, and calculated the corresponding heat exchange capacity. The test data is shown in the table below:
Duty Cycle (%) | Fan Speed (RPM) | Ambient Temp (°C) | Water Flow (L/h) | Water Inlet Temp (°C) | Water Outlet Temp (°C) | Flow Rate (L/min) | Heat Exchange (kW) |
|---|---|---|---|---|---|---|---|
30 | 960 | 23.1 | 190 | 58.1 | 53.2 | 30 | 55.9 |
40 | 1280 | 24.7 | 190 | 59.7 | 53.1 | 29.9 | 75.4 |
50 | 1600 | 25.6 | 190 | 60.7 | 53.1 | 30 | 86.85 |
60 | 1920 | 26.4 | 190 | 61.4 | 52.9 | 30.3 | 97.1 |
70 | 2240 | 26.1 | 190 | 62 | 52.4 | 30.4 | 109.7 |
80 | 2560 | 29.1 | 190 | 64.1 | 53.6 | 30 | 120 |
90 (3kW) | 2900 | 30.2 | 190 | 65.2 | 53.7 | 30.1 | 131.5 |
100 (4.5kW) | 3200 | 27.9 | 190 | 62.9 | 62.9 | 30 | 137.2 |
3kW (With Shield) | 2900 | 30.3 | 190 | 65.3 | 54.3 | 29.8 | 125.8 |
The test results clearly show that as the fan speed increases, the heat exchange capacity of the cooling module improves significantly. This confirms that our high-pressure fan, when paired with the radiator, can effectively handle higher heat loads at higher operating speeds.
In addition to heat dissipation performance, we also verified the stability of the high-pressure fan under CAN control. Throughout the test cycles, the fan operated smoothly at all set speeds without abnormal noise, speed fluctuations, or shutdowns. This proves that the fan maintains consistent performance under industrial-grade control, which is critical for long-term, reliable operation in real-world applications.
What makes these tests especially valuable is that we did not test the fan and radiator separately. Instead, we assembled them into a complete cooling module first, then tested the whole unit under realistic wind tunnel conditions. This integrated testing approach ensures that the performance data we get is close to how the module will perform in actual use, helping us identify any potential issues with airflow matching, installation, or system coordination early on.
This week’s tests are an important part of our quality control and product optimization process. By collecting accurate data in standardized environments, we can optimize the design of our cooling modules and ensure they meet the cooling requirements of different customers. We will continue to conduct such rigorous tests to provide more reliable and efficient cooling solutions for various industries.
