    • The present invention refers to a heat exchanger (6) for exchanging heat between a heated gas and a fluid in particular a gas, wherein the heat exchanger (6) in particular is for a heating apparatus (1) for a recreational vehicle. The heat exchanger (6) comprises a gas conduit (60) configured to receive and to transfer the heated gas and a duct (5) configured to receive and to transfer the fluid to be heated. The gas conduit (60) has a gas inlet (603), a gas outlet (604) as well as a first heat exchange zone (601) surrounded by a corresponding gas pipe and a second heat exchange zone (602) surrounded by a corresponding chamber. The gas pipe surrounding the first heat exchange zone (601) is coupled to the gas inlet (603), the second heat exchange zone (602) is connected to the first heat exchange zone (601) and the gas outlet (604) is coupled to the chamber surrounding the second heat exchange zone (602). The gas conduit (60) is geometrically shaped in such a way that heated gas entering the gas conduit (60) at the gas inlet (603) at first has to flow through the first heat exchange zone (601) and then through the second heat exchange zone (602) before it can leave the gas conduit (60) through the gas outlet (604) The chamber surrounding the second heat exchange zone (602) and the gas pipe surrounding the first heat exchange zone (601) are provided within the duct (5) of the heat exchanger (6). The gas pipe surrounding the first heat exchange (zone 601) is arranged within the chamber surrounding the second heat exchange zone (602) and the gas (inlet 603) is provided with respect to the longitudinal axis of the heat exchanger (6) radially within the gas (outlet 604). Moreover, the present invention refers to a heating unit, a heating apparatus and a recreational vehicle provided with such a heat transfer unit.

    • The invention relates to a radiant-heating device for heating an industrial furnace using radiated heat. A first burner unit (1) comprises a first burner (2), which heats an air mixture by burning a fuel (6), a first air supplier (60), via which the first burner (2) is supplied with fresh air, and a first elongated radiant-heating pipe (20), which includes a rearward end (20a) connected with the first burner (2) and a forward end (20b) spaced from the rearward end (20a) and in which the hot exhaust gas generated by the first burner (2) flows from the rearward end (20a) to the forward end (20b) of the first radiant-heating pipe (20) and supplies heat energy along this path to the pipe wall of the first radiant-heating pipe (20). A second burner unit (1') is constructed like the first burner unit (1). A first connection element (50) connects the rearward end (20a) of the first radiant-heating pipe (20) with the forward end (2Ob') of the second radiant-heating pipe (20'), so that at least a portion of the exhaust gas generated in the second radiant-heating pipe (20') is conducted to the first burner (2) and is burned again using the first burner. A second connection element (50') connects the rearward end (2Oa') of the second radiant-heating pipe (20') with the forward end (20b) of the first radiant-heating pipe (20), so that at least a portion of the exhaust gas generated in the first radiant-heating pipe (20) is conducted to the second burner (2) and is burned again using the second burner.
    • 本发明涉及一种使用辐射热加热工业炉的辐射加热装置。 第一燃烧器单元(1)包括第一燃烧器(2),其通过燃烧燃料(6)来加热空气混合物,第一空气供应器(60),第一燃烧器(2)经由其供应新鲜空气, 以及第一细长辐射加热管(20),其包括与所述第一燃烧器(2)连接的后端(20a)和与所述后端(20a)间隔开的前端(20b),并且所述热排气 由第一燃烧器(2)产生的热量从第一辐射加热管(20)的后端(20a)向前端(20b)流动,沿着该路径向第一辐射加热管 管(20)。 第二燃烧器单元(1')被构造成类似于第一燃烧器单元(1)。 第一连接元件(50)将第一辐射加热管(20)的后端(20a)与第二辐射加热管(20')的前端(20b)接合,使得至少一部分 在第二辐射加热管(20')中产生的废气被传导到第一燃烧器(2),并且使用第一燃烧器再次燃烧。 第二连接元件(50')将第二辐射加热管(20')的后端(20A)与第一辐射加热管(20)的前端(20b)连接,使得至少 在第一辐射加热管(20)中产生的废气的一部分被传导到第二燃烧器(2),并且使用第二燃烧器再次燃烧。
