v 6 Claims.
This invention relates to improvements in heat exchangers, and has for one of its objects the provision of a device of the character indicated wherein the fluid to be treated is utilized for 5 driving a rotor which is within the device and provided for the purpose of agitating the fluid being handled and for preventing accumulation of deposits on the wall of the device.
In heat exchangers, especially those employed for heating oil, carbon forms on the inner walls of the heat exchange chamber which is very objectionable due to its heat insulating characteristics.
It is one of the objects of the present invention to provide a heat exchanger with an agitatorand rotor which contacts with theinner wall of-the chamber of the heatexchanger and serves to keep the same free of carbon or other deposits, this rotor being driven by the fluid to be treated 20 as above mentioned.
Further objects of my invention will be manifest from the following description and the accompanying drawing, in which drawing:
Fig. 1 is a sectional elevation of my improved 25 device;
Fig. 2 is a sectional view on line 2-2 of Fig. 1;
Fig. 3 is a sectional view on the line 33 of Fig. 1;
Fig. 4 is a sectional. elevation of another form 30 of my improved device;
Fig. 5 is a sectional. elevation of still another form; and V Fig. 6 is a cross section of a modified form of heat exchange chamber.
Referring to the drawing in detail, I designates :a tank, reservoir or other source of supply for the fluid to be treated. A conduit 2 extends from the tank I and communicates with a gear pump 3 which may be driven in any suitable manner such 40 as, for example, by an electric motor (not shown). .A conduit 4 communicates with the pump 3 and another conduit 5 one leg of which communicates with a heat exchange housing 6. Within the housing 6 a motor 1 is provided adjacent the point where the end of the conduit 5 enters the housing. This motor comprises a pair of gears 8 and 9 meshing with each other and freely mounted on shafts l and II, respectively. The shaft ll carries a rotor or agitator l2 contained within' the inner chamber l3 of the heat exchanger. This rotor as will be seen from Fig. 3 has fins or projections H on the surface thereof which frictionally engage the inner wall of the 55 chamber I3 so that as the rotor r ta it W ll keep the Walls of the chamber l3 free from carbon or other deposits in addition to agitating the fluid in the chamber.
The motor I is driven by the fluid being treated and which, as will be understood, is supplied by the pump 3 under pressure from the conduit 5. This pressure operated motor is not only very eflicient but as will be understood its use is an economy in that it eliminates the necessity for aseparate drive, including a driving motor, for the 10 rotor.
.hot water or the like may be circulated in the jacket I 5. On the other hand, should it be desired to cool the fluid, cold water, refrigerating fluid' or the like may be circulated through the jacket.
The heat exchange medium is supplied to the jacket I5 through conduit I6 and passes out of the same through conduit l1 back to the source of supply or to waste, as desired.
It will be seen from Fig. 1 that the leg 22 ofthe 25 conduit 5 communicates with the tank or reservoir I and serves as a by-pass for the surplus fluid from the pump 3. This leg is provided with a relief valve' l8 which opens when the pressure in the line rises to a predetermined value to permit the surplus fluid, to return, to its source of supply. The fluid after treatment is passed from the heat exchange chamber l5 through conduit l9.
It will be seen that in this embodiment of my invention the rotor I2 is driven by the fluid being treated all surplus fluid being by-passed back to the supply tank.
The form of my invention illustrated in Fig. 4 is similar to that shown in Fig. 1 except that in this form the by-pass conduit 20 is connected to the heat exchange housing back of the motor 7. In this form, therefore, all of the fluid handled by the pump 3 passes the motor I to drive the same.
In the form of my invention illustrated in Fig. 5 the return line 30 for surplus fluid communicates with outlet conduit l9 so that all of the fluid handled by the pump 3 necessarily passes the motor 1 to drive the same and through the heat exchanger.
In the forms shown in Figs. 4 and 5 the same reference numerals designate similar parts as 5119MB .111 .1 18. 1.
It is to be understood, however, that I do not I wish to be limited to this application of my device as obviously the same may be employed in any installation requiring heatexchange.
Neither do I wish to be limited to the precise construction herein illustrated and described inasmuch as various changes and modifications may be made therein without departing-from thespir it V and scope of my invention.

1. In a heat exchange apparatus the combination of a reservoir of fluid to be treated, a heat exchange chamber, a housing therefor, a driven pump for transferring the fluid from the'said reservoir to said chamber, a conduit leading from the reservoir to said pump, a conduit leading from said pump to said heat exchange chamber, a motor gear insaid housing in communication with said conduit, a shaft for said gear extending into said chamber, a rotor mountedon said shaft, the
