Dc power supply, AC power supply and other products how to choose the right radiator
Time：2023-11-10
Today's topic is that AC power radiators cannot be selected for operation using conventional methods.
500kW load bank
In the work, it is necessary to consider the radiator selection of AC power amplifier. The power amplifier used has a very large capacity, with a current of 40A and a power of 400W.
500kW load bank
My task is to use this AC power amplifier to validate a radiator that can completely dissipate heat at 200W power.
Ac power radiator selection conditions
The AC power radiator is aluminum alloy radiator with fins. The mounting position is restricted, and its height limit is about 40 mm. It must be combined with the forced air cooling of the fan to achieve the heat dissipation of the internal losses generated when the power amplifier power reaches 200W
The actual state that needs to be achieved is a case temperature of 70 °C for the power amplifier at an ambient temperature of 25 °C. In addition, the AC power amplifier is of DIP type with pins on one side of the cooling surface and is 40 mm × 40 mm in size. The shape is slightly irregular and very distressing in terms of installation.
