HEAT PANEL Russian patent published in 2009 - IPC F24J2/26 

FIELD: heating.

SUBSTANCE: invention relates to solar engineering and can be used in solar collectors and in household and industrial heating and cooling devices. A heat panel is made as a row of ribbed pipes for a heat transfer material, the ribbing elements of a pipe are shifted in respect to the ribbing elements of the adjacent pipes in the direction of the pipe longitudinal axis. The end faces of the ribbing elements are inclined at an angle (α and β) to the pipe longitudinal axis. The elements are made as a shell ring closely embracing the pipe and having at least three longitudinal ribs which are set circumferentially along the shell ring perimeter and symmetrically to the plane passing through the pipe longitudinal axis. The adjacent ribbing elements on the same pipe can be shifted in respect to each other around the pipe longitudinal axis. The ribbing elements can be additionally shifted around the pipe longitudinal axis. The longitudinal ribs on the shell ring are set symmetrically to two planes passing through the pipe longitudinal axis. The usage of the heat panel in a solar collector provides for the increase of the heat adsorbing surface square that is open to ray and diffused energy, especially in case of lateral radiation from either side, which leads to the efficiency improvement.

EFFECT: improvement of heat exchange by both convection and infrared radiation.
