11 Claims. 1
This invention relates to cooling or heat exchange units or devices through which air is circulated as a cooling medium. More particularly, the invention relates to units or devices of this class constructed of a plurality of similar blades or vanes assembled to form the unit, and still more particularly wherein means is provided on the blades for circulating air radially through the outer wall portion of the unit as well as longitudinally through the unit. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views, and in which:
Fig. l is a side view of a unit made according to my invention and diagrammatically indicating in dot and dash lines one adaptation and use of the invention.
Fig. 2 is a partial section on the line 2-2 of Fig. 1 on an enlarged scale.
Fig. 3 is an enlarged perspective view of one of V the blades or vanes employed in constructing the complete unit, as seen; in Figs. 1 and 2.
Fig. 4 is a partial longitudinal section through the outer flange of the blade, showing a modification.
Fig. 5 is a side view of the outer wall portion only of a modified form of unit and showing only a part thereof; and
Fig. 6 is a partial section on'the line 66 of Fig. 5.
Thi application constitutes a continuation in part of the cooling unit as disclosed in my prior application Serial Number 524,831, filed March 1, 1944, in which application the general adaptation and use of units of the kind under consideration has been specifically dealt with. The present application deals specifically with the provision of a blade structure having means providing for radial as well as longitudinal circulation of air through the unit to thereby produce more effective and efiicient cooling of the unit as and when greater efficiency in cooling is required.
In illustrating one use of the unit, I have diagrammatically illustrated in dot and dash lines in Fig. 1 of the drawing at H] a radio tube or other electric discharge device upon the anode of which is supported one of my improved cooling units [2. At I3 is shown an electric contact engaging the outer wall at one end portion of the or heat radiating units of the type and kind herein disclosed may be used for many other purposes, and may be of any desired size and structural form.
In constructing the unit, a plurality of similar blades or vanes M are employed, one of these blades is shown in perspective detail in Fig. 3 of the drawing. The blade comprises an elongated body portion l5 terminating in inner and outer flanges l6 and H. The flange l6 extends in the direction of one side surface of the body I5, and comprises an inner part l8 and an offset outer part |9 oifset outwardly with respect to the'part I8. This construction forms an interfitting between the blades or vanes in forming the inner tubular wall portion 20 of the unit, as seen in Fig. 2 of the drawing.
The outer wall portion 2| of the unit is formed from the flanges These flanges have a wide central portion 22, one edge of which joins the body l5 in a rounded bead 23 and at the other edge is a curved or hook shaped flange portion 24. The center portion 22 has longitudinally spaced elongated vent apertures 25 which form on the resulting outer wall 2| circumferentially spaced passages through which air blown into the chambers 26 between adjacent blades can be discharged radially, as will be apparent. In some uses of devices of the kind under consideration, a fan or blower is employed to pass the air in at least one direction to the passages 26. However, in other uses, a normal circulation of air will be generated, and in this latter instance, air will be drawn into the unit through both ends thereof. In these last uses, the unit may be employed as a heat radiating medium, device or apparatus.
In interfitting and interlocking the blades or vanes M, the hook shaped flanges 24 of one blade will-interlock with the bead 23 of an adjacent blade, leaving the apertures 25 freely exposed through the outer wall portion 2|, as will clearly appear from a consideration of Fig. 2 of the drawing. It will be understood that any means may be provided to securely retain the unit. It will, of course, be apparent that cooling B5 elongated apertures as at 25, the flange will have spaced smaller apertures 21, and this flange in alinement with the apertures will have inwardly extending bafiles or deflector plates 28 formed from the material of the flange and in the formation of the apertures 21. In Fig. 4 is illustrated at l5a, part of the body portion of the blade similar to the body portion l5, and at 23a is shown part of the bead similar to the bead 23. The deflectors or baffles 28 extend into the unit or into chambers similar to the chambers 26, and with units employing blades of the kind partially illustrated in Fig. 4 of the drawing, air will preferably be circulated through the unit in the direction of the arrow 29. It will thus appear that the bafiles 28 will serve to pick-up and deflect a forced draft of air outwardly through the periphery of the unit.
In Figs. 5 and 6 of the drawing is shown another adaptationof the invention. In thisconstruction, blades 30 will be employed having inner ends similar to the flanged ends l6 of the blades [4, but instead of having outer flanges running the full length of the blades, the same as the flanges II, the blades 30 will have at their outer ends short flanges 3|. The flanges 3| will have beads 32 similar to the beads 23, and instead of the flat portions 22, will have inwardly beaded portions 33 and hook shaped end flanges 34 which are coupled similar to the flanges 24, forming large openings extending the full length of the blades at the outer part'of the unit, as will clearly appear from a consideration of Fig. 5 of the drawing, In other words, with this construction, a free circulation of air is provided not only longitudinally, but radially through the unit from chambers 35 similar to the chambers 26, and this circulation is obstructed only insofar as the coupling flanges 3| are concerned.
In order to retain the blades 30 against displacement and shifting, the same are further interlocked, for example, by providing apertures 36 in the beads 32 and inwardly projecting knobs 31 on the hook shaped flanges 34 adapted to enter the apertures 36 on the beads 32 of an adjacent blade. However, other means of securing the blades together can be employed.
