Today widespread usage of cooling systems based on heat pipes contributes significantly to the ensuring of electronics thermal regulating conditions. The use of heat pipes as heat exchangers and heat transfer structural members allows creating a new generation of efficient heat removals on their basis. Today the following areas where heat pipes are widely used can be identified: computer equipment from small computers to large data centers, power electronics, and electronics for special purposes. The article analyzes the current state and prospects of using heat pipes in thermal control system of electronic equipment for ground applications.

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 on 3.9 C, and the same value for the pulsating heat pipe is 7.1 C.
