FIELD: mechanics, heating. ^ SUBSTANCE: proposed convector incorporates a heat exchanger with a pipe accommodating heat exchange plates attached thereto. The heat exchange pipe upper arm end part frontal projection features L-shape, while that of the pipe lower arm end can be either L-shape or rectilinear. The convector side wall features two recesses arranged one above the other. The casing depth s-to-casing height h can make either s/h=0.35 to 0.45 or s/h=0.2 to 0.3. the q-to-h ratio, that is the distance between the upper and lower pipe end hole axes-to-casing height ratio, can make either q/h=1.1 to 1.4 or q/h=0.75 to 0.95. The heat exchanger pipe upper and lower arms can be rectilinear. The aforesaid side wall recess can be elongated both upward and downward. The proposed heat exchanger can incorporate one heat exchange unit, or two parallel heat exchange units arranged one above the other. Note that the proposed heat exchange can also incorporate the upper and lower heat exchange units and, at least two intermediate heat exchange units. The convector casing is made from one-piece work part furnished with the top angular openings between the upper and side walls. Every aforesaid opening accommodates an angular fastener covering it, every side wall being furnished with ledges facing the upper wall, while every fastener inside part is provided with the first and second retainers. The aforesaid angular fastener is furnished with a lengthwise grove to receive the convector casing upper wall end face, the said groove being arranged between the second retainers and the lengthwise edge of the angular fastener one side. The angular fastener second lengthwise edge is provided with a shoulder. Note that a slit is arranged between the aforesaid ledge and each first retainer to receive the wall end face of the casing side wall connected with the casing upper wall. Note that the aforesaid slit is arranged at an angle to the aforesaid shoulder corresponding to that between the connected casing walls and that the second retainers are provided with beards to get engaged with the casing side wall. The proposed method of producing the aforesaid casing incorporates cutting one blank from a metal sheet, cutting air release holes in the aforesaid blank, nearby the upper wall, shaping the casing front and upper walls by bending. At least, one side of the said blank is furnished with angular openings. The side walls are bent to form openings between adjacent end faces of the upper wall and the side walls. Now, the upper wall is rigidly coupled with the side walls and the aforesaid openings are covered with the casing angular fasteners. ^ EFFECT: expanded performances of convectors, lower labour input in producing them. ^ 17 cl, 58 dwg |
