The node 10 is designed to connect the heat exchanger 4 with pipes of the heating system (not shown), failed from the bottom of the convector.

Inside the casing 3, on the frame 1, brackets 11 are fixed (Fig. 5) with lodges 12, on which the lower branch 6 of the heat exchanger pipe 7 rests. The brackets are located above the supports 2 of the frame 1, while each bracket 11 is supported by its corresponding support 2, located under the bracket.

The casing 3 (Fig. 1) of the convector includes a front wall 13, a rear wall 14, a left side wall 15 and a right side wall 16. The casing has the form of a duct open from the bottom and closed from above by an air outlet removable grill 17. The casing 3 is connected to the frame 1 .

Assembly of the convector is as follows. On the frame 1 installed in the working position (on which the supports 2 and the heat exchanger 7 are previously fixed), the front and rear walls 13 and 14 of the casing are first put on. To do this, start the ends of the lower and upper longitudinal elements 22 and 25 of the frame 1 (Fig. 9) g-shaped flanging of the front and rear walls 13 and 14 (Fig. 8) and move them along these longitudinal elements so that the ends of the walls are flush with side edges of the frame. After that, the side walls 15 and 16 of the casing are superimposed on the sides, the holes in the transverse flanges 28 are combined with the nuts 29, the screws 27 are inserted into these holes and nuts 29 and the screws 27 are screwed into the nuts, connecting the side walls with the front and rear walls of the casing . In this case, a rigid casing box is opened open from below and from above. Then, a grill 17 (FIG. 1) is laid on top of the casing box obtained from above and the casing takes on the form shown in FIG. 2 - in an arrangement with a frame and a heat exchanger inside the casing. The convector is attached to the floor with screws inserted into the holes 30 of the supports 2.

During operation of the convector, its casing and frame take on various loads from its own weight and the weight of the heat exchanger, and the convector also experiences loads from the mass of at least one human body, which can use the convector as a seat or stand. These loads, taken together by the frame along with the casing, are transferred to the supports 2 and the floor of the heated room, and due to the use of a frame rigidly connected to the casing in the convector structure, these loads do not have a significant negative effect on the strength of the convector. It remains constant throughout the life of the convector.

Thanks to the design described above, the laboriousness of manufacturing the casing and the convector as a whole has been significantly reduced, as well as the laboriousness of mounting the convector has been reduced. Essentially, the convector is made of easily assembled parts, including a heat exchanger and a node for its connection with the pipes of the heating system. Moreover, in the design of the convector, each part of the casing has a simple rectilinear shape, which allows it to be widely changed depending on the required product range, and the connection unit of the convector heat exchanger for universal connection with the pipes of the heating system. The simplicity of each part of the casing, the versatility of the unit, the original connection of the casing with the frame made it possible to manufacture and assemble the convector with minimal cost. At the same time, the carrying capacity of the convector as a whole is significantly increased.
