7 Claims.

This invention relates exchange devices. Moreparticularly, the invention relates to units or devices of this kind constructed from a plurality of similar blades or vanes having interengaging flange portions to form an assembled unit, and still more particu...

larly, to the use of inner and outer rings at edge portions of the blades for'supporting and retaining the blades in the unit relationship. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing,

v 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. 1 is a side View of a unit made according to my invention and indicating in dot and dash lines an adaptation and use thereof. 7

j Fig.2 is an end View of a part of the unit 1 shown in Fig. 1 on an enlarged scale.

Fig. 3 is an enlarged perspective view of one of the blades or vanes which I employ in constructing the complete unit, indicating in dot and dash lines the arrangement of the retaining Fig. 4 is an enlarged and broken sectional view substantially on the line 4-4 of Fig. 2, showing "portions of v inner and outer rings at one end of the unit.

My invention deals with the formation of cool: ing or heat exchange units of various kinds and classes, and to illustrate one adaptation and use, I have diagrammatically outlined in Fig. 1 of the drawing at In an electric discharge device,

to cooling units or heat.

tions 11 of the blades l4 join the flange portions such for example as a radio tube, including an' anode portion I l upon which one of my improved cooling units I2 is arranged. At [3 is also indicated in' dot and dash lines electric contact :hmeans engaging the outer peripheral surface of the unit l2.

In: constructing units of the class under con sideration for .use on the anodes of electric discharge devices of the kind under consideration,

55 and It, and form the radial webs which join the inner and outer tubular wall portions, as will clearly appear from a consideration of Fig. 2 of the drawing.

The flange 15 extends to one side surface of the body H, and has an inner flange portion [8 and an offset-flange portion [9 ofisetoutwardly with respect to the body I! but inwardly with respect to the resulting unit, as will appear from a consideration of Fig. 2 of the drawing. The flange l6 extends to the other side surface of the body H, and has an inner flange portion 20 and an outwardly ofiset flange portion 2|. The flanges 25 and 2| are both of greater width than the flanges l3 and it which compensates for the different diameters of the tubular portions of the resulting unit. These flanges are also curved to produce the desired difierence in diameters of the inner and outer walls of the unit.

The structure of the unit thus described is i1- lustrative of one adaptation and use of my invention, and is shown and. described in the application of Donald L. Spender, Serial Number 524,831, filed March 1, 1944. I

The distinctive feature of my invention resides in shaping blades of the general type and kind described above to provide means for attaching coupling rings, sleeves or cylinders therewith for supporting and holding the blade assemblage in unit form; and to dispense-with the necessity of result is accomplished by cutting out end portions of the flanges t9 and 2| to form notches therein as at 22 and 23 respectively. These notches will provide on inner and outer surfaces and both ends of the blade assemblage, annular recesses for the reception of inner and outer rings, sleeves or'bands24 and 25 respectively.

These'rings, sleeves or bands 24 and 25 will be made to given diameters, and will be circumferentially solid so that the samecan be forceably M. By using the proper number of blades and with the reasonable amount of clearances provided between the interfitting offset flange portions, the blades will be forced into firm position with respect to each other and within and between the pairs of rings 242 5.

It Will be understood that by increasing or decreasing the number of blades or vanes employed, within predetermined limits, pairs of rings 26 and 25 of different diameters may be employed. On the other hand, where insertion or removal of a single blade of the one standard construction would not suflice to produce the desired assemblage between the selected diameter rings or bands, one special blade or vane having slightly narrower or slightly larger flanges can be inserted. The rings or bands 24 and 25 in addition to supporting the blades or vanes in the assemblage forming the unit, also operate to maintain the inner and outer diameters of the unit and produce at the ends of the unit circum ferential continuous inner and outer surfaces.

In addition to employing a drive or snug fit of the rings or bands-24 and 25 upon the blades or vanes, other means such as welding, brazing, soldering or the like may be employed to secure the blades together and the rings or bands to the blades.

In the construction shown, and as will be a parent from a consideration of Fig. 4 of the drawing, the rings or bands 24 and 25 are of the same thickness as the flanges l9 and 2| respectively, so as to maintain flush inner and outer surfaces on the tubular wall portions, and further the width of the rings or bands 24 and 25 correspond to the depth of the notches 22 and 23 so that outer edges of the rings or bands 24 will be flush with corresponding edges of the flanges I8 and 2!.

Having fully described my invention, What I claim as new and desire to secure by Letters Patent is:

A cooling unit for electric discharge devices of the class described, said unit comprising a plurality of similar blades, each blade havin an offset flange at sid portions thereof, the flange of common sides of the blades overlapping and porting the blades in assembled relationship, and said rings being of a thickness corresponding to the thickness of the outer flange portions to lie flushly with exposed surfaces of the outer flange portions.

3.
