HEAT EXCHANGER FOR CONDUCTING ELSEWHERE HEAT ENERGY GENERATED BY HEAT SOURCE

The invention relates to a heat exchanger (10) for conducting elsewhere heat energy generated by a heat source (11) by means of heat energy bound to working fluid in phase transition. The heat exchanger (10) comprises a heat exchanger element (13), which has at least two separate condenser portions (15), and an evaporator portion (14), which is between said at least two separate condenser portions (15). The heat exchanger element (13) and/or heat exchanger (10) has a portion (19) which is broader and/or flatter than the other portions.
