FIELD: process engineering.SUBSTANCE: invention relates to machine building and may be used in woodworking and in radiators for uniform distribution of heat over radiator or board entire volume. Heating board comprises carcass and manifold connected therewith. Carcass is composed of metal sheet with rectangular-cross-section structural tubes arranged there atop. Said manifold consists of two parallel rectangular cross-section circuit tubes and straight lengths of rectangular cross-section manifold tubes. Aligned lengths of structural tune are arranged between manifold tubes. Carcass and manifold aligned at their top are covered by upper metallic sheet every second manifold pipe is elongated starting from hear carrier flow inlet and has chamfer made at the angle directed to heat carrier flow. Said manifold tube covers cross-section of structural tube to divide heat carrier flow into two equal flows. Said flows are directed to opposite structural tune up to heat carrier flow outlet.EFFECT: uniform heat distribution over entire area of heating board, lower costs.2 dwg, 1 ex |
