2 Claims. (Cl. 237--l2) Structures hereinafter described including a radiator, fan, and motor therefor, in combination with a casing, are the subject of my copending divisional application for Letters Patent of the United States for Improvement in heat exchange apparatus, Serial No. 412,972 filed December 10, 1929.

My invention relates to heating systems including a furnace comprising a fuel burner in cooperative relation wi h a container in which any suitable heating fluid, for instance, steam or water, may be heated; and conduits forming a circulatory system leading from and returning to said container and supplying said heating fluid to a radiator or radiators, to heat the atmosphere local to the radiator surface. The purpose and effect of my invention are to facilitate and augment the transfer of heat from the radiator surface to the adjacent atmosphere by more rapid displacement of the air at such surface than is possible by convection; and at a rate variable with the heat supplied.

As hereinafter described, my invention includes a method and means for facilitating and augmenting the transfer of heat from a fluid supplied to a radiator to the atmosphere adjacent to the radiator, by utilizing power from the heating fluid to operate a motor to forcibly circulate the air relatively to the radiator, by means of a rotary fan.

The typical heating system herein disclosed includes a gas burning water heater and means for maintaining a forced circulation of water within the heating system, by an electrically controlled pump; the operation of the device being controlled'by thermostatically operative means; and the forced circulation of air through the radiator is effected by a motor included in a bypass short-circuiting the radiator with which it is associated; so that the heating fluid is taken into the motor. from the supply conduit leading from the heater to the radiator, and the exhaust from the motor is discharged into the return pipe leading from the radiator back to the heater.

My invention includes the various novel features of construction, arrangement and procedure hereinafter more definitely specified.

In said drawings; Fig. I is a diagram showing a house heating system embodying my invention.

Fig. II is a vertical sectional view of one of the radiator structures shown in Fig. I, taken on the line II, II.

Fig. III is a plan sectional view of said structure, taken on the line III, III in Figs. I and II.

Fig. IV is a fragmentary sectionalview of the fluid motor indicated in Figs. I and II.

Fig. V is a fragmentary sectional view. of a modified form of fluid motor.

Referring to Fig. I; the house or other building, comprising rooms or

other inclosures

2 and 3, has, preferably'in the cellar 4 thereof, the heater.,6 inclosing the burners 7 and 8 supplied with gas from the conduit 9 under controlof 55 the thermostatically operative valve in the easing 10. Said valve casing carries the tubular thermostatic element 11 extending within the water conduit 12 which is connected with the pipe 14 through which hot water is delivered 70 from the cellular heater units 16 which are supplied with cold water through the pipe 18. Said conduit 12 is connected by pipes 20 with radiator units 21, from which the water is returned through pipes 23 to the pump 24 which 75 is connected to said pipe 18 and arranged to be operated by the electric motor 25, under control of the thermostatically operative switches 27. Said pump is operated to circulate the water through the system in the direction indicated 0 by the arrows.

Referring to Figs. II, III and IV; each of said radiators 21 comprises a cellular structure which is a rectangular congeries of metal tubes 31 having enlarged polygonal ends 32 which fit together and are sealed in connection with a casing band 33 so as to form a cellular honeycomb of thin metal walls and comprising separate passageways 35 for hot water or steam and 36 for atmospheric air. Said radiator includes the inlet port 38 and the outlet port 39 in communication with said passageways 3 5 for the heating medium. The outer casing 40 for said congeries 31 forms a cold air inlet chamber 41 at the bottom thereof, an intermediate chamber 95 42 containing said cellular structure, and an upper outlet chamber 43 for the heated air. The fluid motor 45 is preferably mounted in said inlet chamber 41 with a fan 46 arranged to force air into said outer casing 40 through the station- 1100 ary louvers 4'7 in the lower portion of said casing and through the passageways 36 in said congeries of tubes, and out from the heated air chamber 43 into the surrounding atmosphere, through the foraminous panel or grill 49.

Said fluid motor 45 includes an outer casing 50 provided with ports 51 and 52 through which the heating fluid in the system circulates from the pipes 20 to the pipes 23. Said casing 50 contains the rotor 54, the blade 55 and the shaft 56 which 1110 is journaled in said casing and in operative connection with said fan 46. Valves 57 and 58 may be provided local to said motor casing to variably determine the relative volume of the heating fluid which shall be directed to the radiator 21 and through the motor, 45. It is to be understood that said valves may be adjusted to variably determine the speed of rotation of the motor andconsequent air displacement effect of said fan 46 to attain the desired efficiency of transfer of heat from the radiator to the surrounding atmosphere; it being noted that such capacity should be increased and diminished in accordance with increase and decrease in the heat supplied to the radiator. Although said fan 46 is indicated as in coaxial relation with said shaft 56, it is to be understood that it may be connected therewith by gearing, so as to be turned at a faster rate than said shaft.

Although I find it convenient to employ a fluid motor of the rotary type indicated in Fig. IV; any other suitable type of motor may be employed. For instance, Fig. V shows a fluid motor 59 of the reciprocatory type. The fan 46 may be mounted directly upon the shaft 60 or, as shown, the fly wheel 61 may be connected by a belt 62 with a pulley 63 on the shaft 65 which carries a fan 46. Said motor 59 may be included in multiple relation with a radiator 21 in a bypass from the supply pipe 20 to the exhaust return pipe 23 and be controlled by valves 5'7 and 53 as above described; but may be otherwise exhausted.

Therefore, I do not desire to limit myself to the precise details of construction, arrangement, or procedure herein set forth, as it is obvious that various modifications may be made therein, without departing from the essential features of my invention, as defined in the appended claims.

I claim:

1. The method of facilitating and augmenting the transfer of heat, to the atmosphere, from a fluid supplied to a'radiator; which consists in forcibly circulating said fluid through said radiator; utilizing power from the heating fluid to forcibly circulate the air relatively to the radiator; controlling the heating effect by varying the proportion of the heating fluid respectively supplied to the radiator and used for circulating the air; and automatically controlling and varying the air circulation by varying the forcible circulation of the heating fluid, inversely with the temperature of the atmosphere local to the radiator.

2. The method of facilitating and augmenting the transfer of heat, to the atmosphere, from a fluid supplied to a radiator; which consists in forcibly circulating said fluid through said radiator; utilizing power from the heating fluid to forcibly circulate the air relatively to the radiator; controlling the heating effect by varying the proportion of the heating fluid respectively supplied to the radiator and used for circulating the air; and controlling and varying the air circulation by varying the forcible circulation of the heating fluid, inversely with the temperature of the atmosphere local to the radiator.
