ABSTRACT:
The invention relates to heat engineering, in particular to heat pipes and can be used for removing heat from miniature high-heat object, in particular elements of radiotechnical instruments and computers requiring efficient removal of heat and minimum dimensions of a cooling system, the aim of said invention is to increase the heat load of an evaporation chamber at a predetermined temperature and to reduce the dimensions thereof. The inventive evaporation chamber for a loop heat pipe comprises a body having a side and an end wall and a capillary-porous orifice provided with steam-outlet channels and arranged inside said chamber. Said steam-outlet channels are united with the aid of a steam header and disposed on the part of the orifice perimeter of the side of a heat sink. Said evaporation chamber is also provided with an asymmetric hold offset in a direction opposite with respect to the heat sink. The ends of the steam-outlet channels are embodiment in such a way that they are dead on one side thereof. The asymmetric hole is also embodiment in such a way that it is dead on the side thereof which is opposite to the dead ends of the steam-outlet channels, the steam header being formed by one wall of the body and the end of the orifice.
