Panel heater for rooms - consists of two outer layers of cardboard with plaster filling between them in which are embedded flow and return pipes

The panel is in the form of a boarded sandwich with the two outer leaves of cardboard (2) enclosing a mass filling (1) of heat or cold storing material such as plaster. A layer of insulation (9) is stuck on the outer surface of the inner leaf. The flow pipe (4) carrying the heating or cooling medium is embedded in the top edge of the panel, and the return pipe is incorporated in the bottom edge. The flow and return pipes are linked by several capillary tubes (3), and the filling is thicker on the side of the pipes further from the room. There are four fixing pints (5) on the panel and the capillary tubes are kinked in those areas in order to bypass them. USE/ADVANTAGE - Panel heater for rooms produces even distribution of heating or cooling and is simple to install.

Heat exchanger system with air cooling

FIELD: heating. SUBSTANCE: heat exchanger system (1) with air cooling includes the inlet manifold (6), containing the plurality of input branch pipes (18), extending therefrom, the heat exchanger (4), connected to the output end of each of branch pipe and containing the inlet header (31), placed on the base frame with ability to move, the outlet manifold and the plurality of heat transfer tubes (34), connecting these two headers, and the connecting element (41, 75), connecting each adjacent pair of inlet headers. The inlet manifold, inlet headers and the connecting elements have a similar coefficient of thermal expansion so, that when the inlet manifold is subjected to thermal expansion, the corresponding thermal expansion of the inlet headers and connecting elements resulted in the inlet headers movement relative to the base frame to the distance, corresponding to the thermal expansion of the inlet manifold. EFFECT: in the heat exchanger system with pipe voltage air cooling, connecting the inlet main pipe of the inlet manifold and each heat exchanger, is minimized through the use of the simple structure. 11 cl, 8 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 618 775 C2 (51) МПК F28F 9/00 (2006.01) F28D 1/04 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ФОРМУЛА (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ 2015112307, 14.08.2013 (24) Дата начала отсчета срока действия патента: 14.08.2013 Дата регистрации: (73) Патентообладатель(и): ТИЙОДА КОРПОРЕЙШН (JP) Приоритет(ы): (30) Конвенционный приоритет: 06.09.2012 JP 2012-195924 (56) Список документов, цитированных в отчете о поиске: JP 2012037069 A 23.02.2012.
