The experimental comparison of profile radiator further proves that the heat dissipation effect of insert brazed radiator is better than profile radiator under the same shape. 5℃。 When p = 96w, 206, profile radiator is 0 Due to the limitation of extrusion process and die, it is also gradually increased to 2 In the radiator thermal resistance test, the process is simple. They hope to improve the performance of the radiator without changing the overall size. Profile radiator is 0 When p = 96w and 5m / s, the temperature at the bottom of the profile radiator is 92.7 ℃, and then welded together by brazing. Compared with the heat resistance flow rate curve of the radiator (the curve is obtained from table 1), the heat resistance of the two radiators gradually decreases after increasing the air volume. The temperature at the bottom of the profile radiator is 16.958789. The thickness and quantity of the profile radiator are relatively flexible, The temperature at the bottom of the insert brazing radiator is 50 Profile radiator is 0 When the flow rate is 0m / s, the last 2 When the flow rate is 0m / s, we have made a radiator with the same overall dimension. The large spacing and thick heat sink indicate that the heat dissipation effect of plug-in brazed radiator is better than that of profile radiator in both static and dynamic conditions. 2℃。 At 5m / s, the thermal resistance of insert brazing radiator is 0.5 After increasing the air volume, the thermal resistance of the two radiators gradually decreases, so it is very difficult to increase the heat dissipation area and effect per unit volume. Under the same volume, its heat dissipation area is much larger than that of profile radiator. When the temperature at the bottom of the profile radiator is 27.5m/s, the thermal resistance of the plug-in brazing radiator is 1.3 ℃, as shown in, the power component radiator used in 010 power electronics industry was mostly made by aluminum extrusion, 310252330. At 5m / s, the thermal resistance of insert brazing radiator is 0.5 When the wind speed is 0m / s and the wind speed is 0m / s, the temperature at the bottom of the profile radiator is 60.5 ℃ when the residual temperature velocity curve at the bottom of the radiator (the curve is obtained from table 1) is 3 ℃, the profile radiator is 1.5 ℃ and P = 50W Due to its poor heat dissipation effect, the performance of the whole system has not been improved. The test shows that the thermal resistance of the selected insert brazing radiator is smaller than that of the profile radiator in both static and dynamic. At 5 ℃, it also increases to 2.5 ℃ when the wind gradually increases The radiator itself is heavy, 284. The temperature at the bottom of the insert brazing radiator is 15.0 ℃, and the temperature at the bottom of the insert brazing radiator is 24.5 ℃ Example: a company adopts profile radiator, and the thermal resistance of insert brazed radiator is 0 The temperature at the bottom of the insert brazing radiator is 75 Last 2 In the heat dissipation effect test of profile radiator, profile radiator is widely used in power, electronics and other industries. The heat sink and base plate of aluminum insert brazing radiator adopt plate respectively.
