APPARATUS FOR GENERATING HEATED AIR Original Filed April 26, 1960 iiii INVENTOR Ni kolc s Loing ATTORNEYS United States Patent APPARATUS FOR GENERATING HEATED AIR Nikolaus Laing, Stuttgart, Germany, assignor, by mesne assignments, to Laing Vortex, 1116-, New York, N.Y. Original application Apr. 26, 1960, Ser. No. 24,807, now
Patent No. 3,152,876, dated Oct. 13, 1964. Divided and this application Sept. 15, 1964, Ser. No. 396,761
7 Claims. (Cl. 165-86) This invention relates to means for generating a stream of heated air. The application is a division of application Serial No. 24,807, filed April 26, 1960, now Patent No. 3,152,876, granted October 13, 1964.
The invention is concerned with apparatus of the type comprising a cylindrical bladed rotor and guide means cooperating therewith to induce a flow of air from an inlet side of the rotor through the path of the rotating blades of the rotor to the interior thereof and thence again through the path of the rotating blades to the outlet side of the rotor. The invention provides apparatus of this type having hollow blade portions and means for circulating a hot fluid, for example hot Water or steam, through the hollow blade portions so that in operation of the apparatus heat is transferred from the hot fluid within the blade portions to the air which is caused to flow past the exterior thereof.
More specifically, the invention is concerned with a rotor construction for apparatus of the type above specified wherein the blade portions are interconnected by a series of preferably hollow rings disposed in planes extending perpendicularly to the rotor axis and spaced therealong, the rotor being built up from a stack of annular elements formed of sheet material, the elements being of a plurality of different groups and secured together in predetermined recurring sequence going along the length of the rotor: in a simple construction there may be two groups of elements which are arranged in alternation, elements of one group providing one side of a ring, and those of the other providing-the complementary side of the ring and also blade portions which mate with apertures in the next ring of the first group.
One embodiment of the invention will now be described by way of example with reference to the accompanying somewhat diagrammatic drawings in which:
FIG. 1 is a schematic transverse section through an apparatus for generating a stream of warm air;
FIG. 2 is a partial longitudinal section through a rotor for the FIG. 1 apparatus;
FIG. 3 is a partial transverse section of the FIG. 2 rotor taken on the line IIIIII thereof; and
FIG. 4 is a partial longitudinal section of the FIG. 2 rotor illustrating the manner of its constructions from stacked sheet metal elements: for better illustration FIG. 4 is somewhat enlarged and distorted.
The apparatus comprises a bladed rotor 1 and guide means in the form of a pair of guide walls 2, 3. The rotor 1 has a series of similar curved blades 7 extending parallel to the axis and arranged in a ring thereabout: the blades are concave facing the direction of rotation, indicated by the arrow 8, and have their outer edges leading. The means for driving and supporting the rotor 6 are of conventional type and are not shown. The guide 3 has its lower poriton returnbent to form a main guide wall portion subtending a small angle (some at the rotor axis and defining with the rotor a gap 16 which, in the particular embodiment shown, converges in the direction of rotor rotation. The line of nearest approach of the main guide wall portion 15 to the rotor 1 is about diametrically opposite that of the guide wall 2 and both lines of nearest approach are well spaced from the rotor. The main guide wall portion 15 terminates at the air inlet region 12 in a rounded-out lip 17 and on the outlet side merges into the remainder of the wall 3 in a rounded nose 18.
The rotor 1 on rotation cooperates with the guide means formed by the main guide wall portion 15 and the guide wall 13 to induce a flow of air from the inlet region 12 through the path of the rotating rotor blades to the interior of the rotor and thence again through the path of the rotating blades to the outlet side of the rotor. The flow paths through the rotor are shown by the chain dotted lines F. Though notshown in FIG. 1, it will be seen from the following that the rotor 1 has hollow blades through which hot fluid is circulated e.g. hot water or steam; the air stream which is caused to pass outside of the blades derives heat from the fluid circulating Within them.
Turning now to FIGS. 2 to 4, the rotor 1 shown in part in FIG. 2 comprises hollow end support members 31 (one only being shown) between which there extends, parallel to the rotor axis 32, a series of similar hollow blades 33 having the curved profile shown in FIG. 3. The end support members 31 have hollow stub shafts 34 whereby they are supported for rotation about the axis and driven and through which the hot fluid is passed, with the aid of conventional connections and seals, not shown. The fluid enters one support member 31 via its stub shaft 34, passes longitudinally of the rotor to the other end support member, and thence out through the stub shaft thereof. The rotor 1 includes a plurality of rings 35 which are disposed in planes extending perpendicularly to the rotor axis 32 and spaced uniformly therealong. Like the blades 33, the rings 35 are hollow and their interiors intercommunicate with those of the blades through openings 35a. The distribution of fluid into the blades 33 from the upstream end member 31 is eifected so that alternate blades have a higher pressure than those between them, so that fluid flow takes place in the rings 35 between adjacent blades. The rings 35 are constructed intermediate the blades 33 so that their walls contact each other along the lines 36. This constriction causes flow to take place along lines indicated at 37, and reduces the rate of flow in the rings while at the same time directing this flow to the outside.
The rotor 1 is built up from a nested stack of annular elements 38, 39 formed of sheet material. The elements 38 are all similar to each other: the elements 39 are all similar to each other. The stack is made up of elements 38, 39 in alteration. Each element 38 provides one dished wall 40 of a ring 35, and a series of blade portions 41 pressed out to one side of the wall and terminating in inturned ends 42. The elements 39 each provide the opposite dished ring wall 43, with apertures 44 for alignment with the blade portions 41 on the element 38 and have an axially extending peripheral flange 45. The annular elements 38, '39 are stacked with the flange 45 of an element 35! engaging over and locating on the periphery of the adjacent element 38. The next element 38 is then located by entry of the inturned ends 42 of its blade portions 41 in the apertures 44. The stack when assembled is secured by any convenient conventional method e.g. brazing: the flanges 45 can be spun over the adjacent elements 38 as illustrated at 46. The method of manufacture from a nested stack of annular elements permits of economic quantity production.
It is to be appreciated that no guide means are shown for the rotor 1 of FIGS. 2 to 4, but that these guide means can take the form ilustrated in FIGS. 1 and 2. As a blower, the rotor 1 and its guide means operate as above described. As a heat exchanger, it is to be noted that the surfaces of the blades 33 and rings 35 through which the heat passes encounter a current of air which changes direction twice in every revolution: this minimizes the insulating boundary layer of air such as is set up on surfaces over which the air movement isin one direction only, and promotes efliciency of heat transfer.
I claim:

A rotatable bladed rotor for use in apparatus for generating a stream of air and for effecting a heat exchange between air passing over the blades of the rotor and a second fluid wherein said apparatus has guide means which on rotation of the rotor cause air to flow from a suction side of the rotor, through said rotor, and thence to a pressure side of said rotor; said rotor comprising a stack of annular elements secured together and positioned coaxially with respect to said rotor with the stack defining hollow blade portions extending parallel to the longitudinal axis of the rotor, fluid passages intercommunicating said hollow blade portions to form a system of internal ducts in the rotor, and means for introducing fluid into and removing fluid from said ducts.
