HEAT ACCUMULATOR AND METHOD OF ITS FABRICATION Russian patent published in 2014 - IPC C09K5/06 F24J1/00 

FIELD: transport.

SUBSTANCE: invention relates to a heat accumulator for the adjustment of heat conditions of the device incorporated within a spacecraft. The invention covers also the method of fabrication of this device. The accumulator comprises a cellular structural element 3 with multiple cells. Every cell is filled with capsules with a heat accumulating material and a heat conducting filler containing the heat conducting material and an adhesive with the heat conductivity varying from 5 to 29 W/(m.K). The accumulator is fabricated by bringing an initial material 2 composed of the mix of capsules and the heat conducting filler in contact with the cellular structural element 3 with the closure of at least one surface of arrangement of the cells of the element 3, compaction of the initial material at 4-10 MPa, filling of every cell with the material 2 and solidification of the heat conducting filler after the cell filling.

EFFECT: light and inexpensive heat accumulator of good heat conductivity can be obtained.
