TWO-PHASE DEVICE FOR COOLING POWERFUL ELECTRONIC SYSTEMS

The paper presents the results of experimental studies of the characteristics of a two-phase heat transmitting device (thermosyphon) that includes a fl at copper evaporator with capillary grooves and a multipipe heat-exchanger– condenser intended for ensuring the temperature regime of powerful electronic and electrical devices. The capillary grooves of the evaporator can be coated with a layer of porous sintered copper powder. Heat removal from the thermosyphon condenser can be carried out by liquid or air fl ow. When using water as a coolant, the heat fl ux transmitted by the thermosyphon is more than 1 kW
