In general, heat exchangers are classed as radiators or convectors. Each possesses obvious advantages as well as disadvantages.
Inherently radiators are bulky heavy structures of high initial cost and practical considerations have dictated that radiators, particularly for home heating installations, be made of iron castings. Of necessity these castings are standardized dimensionally to obtain mass production. Installation is usually burdensome and lengths must he compromised to multiples of the lengths of the individual sections. Joining of the sections together entails excessive labor costs and frequently obtains leaking joints. On the other hand, radiant heat is prolonged and gives more comfort.
Convectors, of course, are relatively less expensive than radiators. They provide fast heat but must be operated at higher temperatures than radiators. Because they must chimney to effect air movement they are more susceptiblerto malfunctiom'ng if not properly installed. The heating is akin to yhot air systems and must be cycled more frequently than radiators. Fluctuations in temperature are noticeably more pronounced than with radiant heating which has a more stabilizing effect upon the human body.

Embodiment of FIGURE 8 It will be noted that this modification in essence is similar to'that of FIGURES 1-7 and like parts are identitled with corresponding numerals. In the present instance the radiator portion identified 3a is modied to the extent that the fluid conduits are formed as cylindrical top and bottom tubes or pipes lili) and 101 and the securing flanges 3h and 31 are integral with the rear side 23 of panel 5 and the members 37 and 38 extend at their forward portions therebetween. The manifold 104 is suitably modified to provide upper and lower nipples Which connect to the pipes 160 and 101.
Embodiment of FIGURE' 9 The structure of FIGURE 9 is similar to the previous embodiments and parts corresponding thereto are identified by identical numerals. In the present instance the structure is adapted to electrical heating and the upper and lower tubes lliltla and lilla are split longitudinally as at 125 and 126 and admit and mount the heating elements such as calrods 127 and 128 respectively. Elements 127 and 128 have nut and bolt means 130, 131 to connect to associated electrical conduits.
In essence in each embodiment the front port-ion of the unit functions as a radiator and the rear portion as a convector. The arrangement of the various parts is such that the structure is particularly adaptable to extrusion which provides the necessary connecting and mounting means so that the parts of the unit may be easily assembled by stacking the fins endwise into the front portion. Various lengths as required are easily made by cutting off the excess. -The structure is comformable to uneven Walls and can easily be adapted around minor obstructions. A novel interlocking arrange- `ment of the ilus with the radiator panel is allorded and the nature of the interlock provides a stiifening beading for the front panel and is highly adaptable to extrusion.
Having describedrseveral embodiments of the invention it will be understood that these variations are not disclosed byway of limitation but that various other forms of the invention will become readily apparent to those skilled in the art within the scope of the appended claims.

2. An extruded metal heat exchanger for attachment to a building wall and having a radiant portion comprising an elongate structure presenting inner and outer surfaces, means providing a conduction for a heating medium in said radiant portion and having inlet and outlet ends, and said radiant portion having a pair of transversely spaced integral securing flanges projecting outwardly from said inner surface, and convector elements positioned against said inner side of the elongate structure and deining vertical convector passages, with an air inlet extend-k ing from below said radiant portion rearwardly to said building wall and an air outlet above the passages extending above said radiant portion in front of said building wall, each element having an abutment flange with end portions adjacent respective securing iianges, said abutment flange engaging said inner surface of the elonate structure, each said element further having a wall connected to said abutment flange and projecting away from said structure, said wall being notched adjacent said end portions of the abutment flange whereby said securing lianges being bendable are adapted to be bent over said end portions by entering into respective notches.
3. An extruded metal baseboard heating structure comprising a radiator portion for attachment to a wall, said radiator portion including conduit means having fluid inlet and outlet means at opposite ends, said radiator portion presenting vertical spaced back `and front surfaces, a convector structure behind the radiator portion and comprising a plurality of plates spaced side by side in laterally aligned relation and defining vertical air passages therebetween with an air inlet therebelow and an air outlet thereabove, said plates having top and bottom ends with notches and vertical surfaces therebetween opposing the back surface of the radiator portion, said surfaces on the plates and said back surface on the radiator portion in preassembly having non-mating contours, and bendable liange means projecting from said back surface of the radiator portion and embracing the ends of the plates, said iianges being bent over said ends of the plates and extending into said notches and securing said plates against said radiator portion under stress mating said surfaces on the plates with the surface on the radiator portion.
4. An extruded metal thermal unit comprising a front horizontally elongated radiant section having front and rear sides and a rear convector section, said radiant section having means providing inlets and outlets for associated heating medium, said radiant section having a rear surface with convector connecting means including extruded longitudinal bendable flanges, said convector section comprising a plurality of iin elements stacked side by side each having an edge portion presenting a surface in abutment with said rear surface of the radiant section Jfor establishing thermal conductance therebetween, one of said surfaces being iiat and the other being convex, and means including said flanges holding said lin elements edgewise under tension along their edges remote from the rear surface and under compression along their edges against the rear surface with the surfaces on said elements in conformance with the rear surface and .in complementary engagement therewith, said elements having a fulcrum reaction against the convector section to provide good `thermal contact therebetween, said elements delining convection air passages therebetween having air inlets at their lower ends and air outlets at their upper ends.
