PATENTED OCT 1 2 I971 SHEET 2 [IF 2 u l w W4. 5 m M m ROTA'I'ABLE HEAT TRANSFER MEANS BACKGROUND OF INVENTION The rotary devices, as agitators and turbine blades, are provided with passages forming part of cooling or heating systems to control the temperature of these parts during the operation of the machines. Examples of these structures are shown in U.S. Pats. No. 1,667,944, No. 2,778,601, and No. 2,883,151.
SUMMARY OF INVENTION The invention relates to a moving apparatus for transferring heat from a heat transfer means to a fluid surrounding the apparatus. The apparatus has a stationary member rotatably carrying a movable member. Secured to portions of the movable member are outwardly directed structures carrying the heat transfer means. The heat transfer means may be a plurality of tubes secured to the movable member in fluid communication with inlet and outlet passages. In one form of the invention, the heat-conducting members may be electrically heated elements surrounding and insulatively secured to the outwardly directed structure, as a fan blade mounted on the rotatable member. n rotation of the movable member, the surrounding fluid, as air, is moved past the apparatus so that a continuous stream of fluid engages the heat transfer means whereby heat is transferred to the surrounding fluid. In another form of the invention, the stationary and movable members are provided with pmsage means for carrying a fluid, as water. A pump, having a rotatable member located in the passage, is operable to move the fluid through tubes surrounding the fan blades mounted on the rotatable member.

FIG. 2 is an enlarged sectional view taken along the line 2- 2 of FIG. 1;
FIG. 3 is an enlarged sectional view taken along the line 3- 3 of FIG. 1;
FIG. 4 is a fragmentary longitudinal sectional view of the heat transfer apparatus; and
FIG. 5 is a sectional view taken along the line 5-5 of Fl 4.
Referring to the drawings, there is shown in FIG. I a heat transfer apparatus of the invention, indicated generally at 10, operable to transfer heat energy to a surrounding fluid medium, as air. Apparatus comprises a stationary member 11 attached to a support 12, shown in FIGS. 2 and 3, with a plurality of bolts 13. The support 12 may be an internal combustion engine block having passages for cooling fluid, as water. The apparatus is usable in any environment to transfer heat to a surrounding fluid medium.
A movable member, or hub 14, is rotatably mounted on the stationary member ll adjacent the support I2. A pulley ring 16, having an outwardly open groove for a V-belt or other power transmitting means, is secured to the front face of the hub with a plurality of bolts 17. A plurality of identical fan blades I8, 19, and 21 are secured to and extend radially from the circumferential face or side of the hub 14. As shown in FIG. 3, each blade has a slight rearwardly directed curvature whereby upon rotation of the hub the blades move the surrounding fluid past the heat transfer apparatus 10.
Associated with each blade are a plurality of heat conductors, indicated generally at 22, operable to transfer heat energy to the surrounding fluid medium. The conductors 22 comprise a plurality of side-by-side radial tubes 23 having inlet ends 23A coupled to the hub 14. In a similar manner, on the opposite side of the blade, outlet means 238 of the tubes 23 are attached to the hub 14.
A circular tubular ring 24 concentrically surrounding the hub 14 is secured to peripheral portions of the blades 18, 19, 20, and 2|. The ring 24, as shown in FIG. 2, has an annular passage 26. Outer portions of each tube 23 are secured to the ring 24. The passage of each tube 23 is open to the circumferential passage 26 so that all of the fluid moving through the tubes 23 must flow through the passage 26. The circumferential ring 24 functions to balance the rotary member and equalize the fluid pressure on all of the tubes.
The tubes 23 are spaced from the opposite faces of the blades by a plurality of laterally projected radially spaced fins 27. The fins 27 extend in a generally tangential direction and are secured at their inner ends to the opp'osite faces of the blades. The fans 27 increase the efl'iciency of heat transfer from the heat conductors 22. The generally tangential fins 27 cause slight turbulence of the air as it moves past the tubes 23. This type of air flow increases the rate of heat transfer. The fins 27 may be corrugated, Iouvered or interrupted in construction and preferably made of heat conductive material, as copper, aluminum, or the like. Tubes 23 can be secured directly to the blades or fonned in the blades.
As shown in FIG. 4, the stationary member 11 has a forwardly directed tubular member 28 having an axial inlet passage 29. The passage 29 is in alignment with a discharge port 31 in the support I2. Mounted on stationary member II is a rear bearing 32 and seal 33 for carrying the inner end of hub 14. The outer end of hub 14 is carried on a similar bearing 34 located adjacent a seal 36. A nut 37, threaded on the outer end of tubular member 28, holds the hub 44 in assembled relation on the stationary member 11.
An upper portion of the tubular member 28 has several elongated openings 38 in alignment with an inlet annular chamber 39 on the inside of hub 14. Extended radially outwardly from chamber 39 is a passage 41 leading to an axial inlet header 42. A plurality of radially directed feeder bores 43 connect the header 42 to the inlet portions 23A of the tubes 23. Spaced from the header 42 is a return header 44 connected with bores 44A in fluid relation with the return or exit portions 23B of the tubes 23. A passage 45 extends inwardly from the header 44 to an annular chamber 46 leading to an axial exit pasage 47 in the stationary member II. The passage 45 is open to an annular exit chamber 46 in communication with the exit passage 47 in the stationary member 11. Passage 47 is in alignment with an inlet port 48 in the support 12. Both the annular chamber 46 and the exit passage 47 are located radially outwardly from the inlet passage 29 and the inlet chamber 39 so that the centrifugal force acting on the fluid in the system will cause the fluid to flow from the inlet chamber 39 into the inlet header 42 through the tubes 23 and back into the outlet header 44 and outlet chamber 46 into the exit pc 47. Each of the conductors 22 associated with a blade is connected to separate inlet and exit headers coupled to the annular chambers 39 and 46.
An increase in the flow of the fluid through the system is accomplished with the use of a pump, indicated generally at 49. The pump 49 has a rotor comprising an elongated axial shaft 51 carrying a plurality of circumferentially spaced blades or vanes 52. The shaft 51 is rotatably mounted on a pair of spaced bearings 53 and 54 carried in a removable threaded plug 56. The plug 56 is removably attached to the forward end of the stationary tube 28. Secured to the outer end of shaft 51 is a pulley 57 having an outwardly directed V-groove for accommodating a V-belt, or other power transmitting means, used to transmit power to the pump. The vanes 52 are located within the passage 29 immediately adjacent the opening 38 so that on rotation of the vanes fluid will be forced through the opening 38 into the annular inlet chamber 39.
Located adjacent the inlet side of the pump 49 in the pasage 29 is a restrictor plug 58 having a centrally located throat 59 immediately adjacent the inlet ends of the vanes 52. The fluid flowing in the axial direction of the arrow 61 moves through the throat 59 and fills the pump with a rapidly moving fluid. The pump 49 can be operated at varying speeds to control the flow of fluid through the system. In addition, the pump can be operated independently of the rotation of the hub I4 so that the fluid can be moved through the system at times when the hub is not rotated.
The fluid in the system can be a liquid or gas which carries heat energy. The heat energy is dissipated through the plurality of tubes 23 located adjacent the surfaces of the blades 18 to 21. This heat energy is transferred to the surrounding fluid medium which may be air, water, or like fluids.
The blades 18 to 21 can be increased or decreased in number and attached in numerous ways to the hub 14. Preferably, the blades are secured by welds to the hub. in addition, the blades may be integral with the hub. The tubes 23 may be located only on the leading side of the blade where they engage a majority of the air moved by the blade. The tubes may be circumferentially coiled around each blade. Each tube can be split into several branch tubes to that the number of tubes increase along the radial length of the fan blade. in addition, the blades may be mounted in a plurality of longitudinally spaced rows along the the hub to increase the heat transfer capacity of the apparatus.
The heat conductors 22 can be an electrical heating element, as electric heating wires or bands, insulatively mounted on the blades. The stationary member 11 and rotatable member 14 can be provided with suitable brushes and slip ring: to complete the electric circuit to transfer electric power to the heating wires. The stationary member can be an electric motor carrying the rotatable member and its blades.
