HEAT LOOP PIPE Russian patent published in 2013 - IPC F28D15/00 

FIELD: heating.

SUBSTANCE: heat loop pipe includes evaporator consisting of several cylindrical housings located near each other and having common compensation cavity divided into two parts. Capillary porous head pieces arranged inside each cylinder are sealed on their end faces so that two parts of compensation cavity can freely rotate through feed channels with each other, and at the same time so that they cannot have any connection to steam discharge channels. In order to supply heat to cylindrical housings, the latter can be built in a common contact flange from conductive material. When using heat loop pipe for heat exchange with fluid media, cylinders can be equipped with ribs (for example longitudinal) from conductive material, or external surface of the cylinders themselves is used to perform heat exchange with fluid medium; at that, cylinders can be installed in rows in a staggered order.

EFFECT: enlarging the surface of heat removal zone of evaporator of heat loop pipe; reducing the temperature gradient in contact zone of evaporator with cooled item.
