| Summary: | The given article presents the results of an experimental comparison of three radiators which are: pressed radiator made of aluminum plate (basic variant), radiator made of copper wire, and copper/water pulsating heat pipe. The radiators are intended to take off heat from the LED module with the power capacity of 10,55 W. It is established that under natural convection all three radiators can keep temperature level of the circuit board module less than 64 C that lies within the operating range. In comparison with basic variant, the use of the copper wire radiator allows lowering of the temperature in the LED module center to 3.9 C, and the same value for the pulsating heat pipe is 7.1 C. |
