Patent ID: 7027725

Claim:
A heating panel, comprising: upper and lower plates integrally formed to face each other so as to form an inner fluid pathway in which heating water flows; a plurality of connecting members, each symmetrically extending from the upper and lower plates toward the lower and upper plates, respectively, and connecting the upper and lower plates to each other; an inner fluid pathway formed at an inside of the plate by the plurality of connecting members; and two fluid communication portions for supplying and discharging the heating water, wherein each of the connecting members extends at a sloping angle, such that upper and lower sides of the connecting member, facing each other while symmetrically extending from the upper and lower plates, respectively, converge to a bottom plane located at the center of the connecting member, and is defined with a circular or elliptical shape, respectively, at upper and lower portions of the connecting member where the connecting member starts to extend from the upper and lower plates, forming a circular or elliptical inner fluid pathway in the heating panel, wherein each of the connection members is defined with a groove by being extended toward the upper and lower plates from a periphery of the bottom plane of the connecting member, deviated from the center of the bottom plane of the connecting member, where the upper and lower plates are connected.
