RADIANT PANEL

PROBLEM TO BE SOLVED: To provide a radiant panel etc., that has superior cleanness on a radiant surface and can suppress dew condensation.SOLUTION: The present invention relates to a radiant panel comprising a radiant member 20 capable of exchanging heat with the external environment through heat radiation, and a heat transfer pipe 10 capable of exchanging heat with the radiant member 20 as a heat transfer medium flows inside. The heat transfer pipe 10 is a long-sized metal extrusion molding comprising a plurality of pleats on an internal surface substantially in parallel with the flowing direction of the heat transfer medium, and the radiant member 20 is a long-sized metal extrusion molding comprising radiation fins having smooth curved surfaces or smooth planes interfacing with the external environment, and a storage part 21 in which at least one heat transfer pipe 10 can be housed in a heat conductive state while penetrating in a longer direction. The radiant panel comprises a plurality of unit panels 1 each housing the heat transfer pipe 10 in the storage part 21 of the radiant member, and heat transfer pipes housed in the plurality of unit panels 1 are interconnected by dry joining using crimping.SELECTED DRAWING: Figure 4 【課題】放射面の清掃性が優れて、かつ結露を抑制できる放射パネル等を提供する。【解決手段】外界と熱放射により熱交換しうる放射部材と、伝熱媒体が内部を流動して放射部材２０と熱交換可能な伝熱管１０とを備えた放射パネルであって、伝熱管１０は、内部表面に伝熱媒体の流動方向に略平行に複数のヒダを備えた長尺の金属押出成形物であり、放射部材２０は、外界との界面が平滑な曲面又は平滑な平面である放射フィンと、少なくとも１本の伝熱管１０を熱伝導可能にかつ長尺方向に貫通して収納しうる収納部２１とを備えた長尺の金属押出成形物であり、伝熱管１０を放射部材の収納部２１に収納した単位パネル１を複数備え、かつ複数の単位パネル１に収納された伝熱管相互の接続が、カシメを用いた乾式接合である放射パネル。【選択図】図４
