<p>The inventive heating panel is designed in the form of a row of finned pipes for a heat carrier, therein said finning elements (2) are arranged on a pipe (1) in such a way that they are offset along the longitudinal axis thereof in relation to the finning elements of the other pipes. The end faces of the finning elements are chamfered at an angle (a and ß) to the longitudinal axis of the pipe. Said finning elements are made in the form of a collar (3) which tightly embraces the pipe and has at least three longitudinal fins (4, 5) disposed along the collar circumference symmetrically with respect to a plane passing along the longitudinal axis of the pipe. The use of the heating panel in a solar collector makes it possible to increase the surface area of a heat-absorbing surface which is accessible for directed and scattered energy, in particular for lateral radiation coming from any side, thereby increasing efficiency. The use of the heating panel in public service and industrial heating and cooling devices makes it possible to improve heat-exchange conditions by convection and infrared radiation. In addition, the finning elements may be also offset about the longitudinal axis of the pipe. In such a case, the longitudinal fins are disposed on the collar symmetrically with to two planes passing along the longitudinal axis of the pipe, thereby additionally increasing efficiency.</p> |
