and on the coil.
More specifically the present invention provides a heat exchanger of type hri ei'ly' out=- lined above in which the terminals the heat coil, extend to the exterior of the casing and are her ing element, as well as the terminals of rnetically sealed thereto.
My device as will be brought out hereine use of a drying cloth, for instance, purposes is avoided. In the drawing:
Fig. l is a sectional elevational view of embodiment of my invention; and
Fig. 2 is a section on the line 2-2 of Fig. 1. Referring to the drawing "in detail, 1 desig=-' nates the casing of my improved apparatus, this casing being composed-of material which is free of occluded gases and capable of withstand-= ing high temperatures without disintegration. Glass, pyrex or other vitreous materials, quartz, etc. are examples of materials havingthe above mentioned characteristics. If it be desired to employ a metallic or other material which contains or may contain occlude d gases, and/or which may give oil or liberate deleterious gases when heated, such material must first be treated to prevent such gases entering the heating chamber, the desideratum being operation of the elements sealed in the heating chamber under conditions which will insure preservation and proper functioning of the apparatus.
water to be heated "passing From a broad standpoint the present invention comprises a hermetically sealed cas ng providing a heating chamber for a coil containingthe liquid to be heated and an electrically operated heating element for the coil, the casing being of gases (oxygen for instance) capable of ha a ing a deleterious effect on heating elenent (Cit Palt llS understood such will be passed t1 the jacket before entering the coil. A ie'show 2 in the drawing, this jacket and outlet e no jacket is employed then wise treating the inside i so that the same will function the casing is a metallic pipe o opper, oiclrei or other suitable I or other liquid be heater 1'; above mentioned is GillplGf/d let end oi: tne tube 5 is connected to the C11.
-e jacket. other handif no i GlTilQiJHGG. then will be understood tl inlet end or the tube 5 will'be connectedv liquid supply source.
tube 5 is closely coiled helically with; casing i, the coils i ne provided abutting other. The outlet oi the tube is open ended passes to ""ie exteri r or" the casing. Inas .iuch as one of e objects of this invention is pro vide against the presence of deleterious within the heating chamber provided by t ing 1, the tube 5 will be of such materia treated as to be incapable of liberating inj gases when the device is in operation. For i ample, the tube could he heated initially so to drive out any occluded gases.
The inlet and outlet portions of the tube 5 are hermetically sealed to the casing 1. This her-= metic seal is conveiuently provided, by brazing a copper bushing or apron 9 to the tube 5 and annealing the same to the casing 1, when the latter is of glass, for instance. If a metallic casing 1 is employed then any of the many well known methods of obtaining a hermetic seal may be employed.
The coils l of the pipe or tubing 5 surround and are in close proximity to a heating element designated it. This heating element, for punposes of illustration only, has been shown in the form of a filament, but may take other forms as is to be understood.
The filament of the heating element 10 is conveniently supported by wires 11 on an insulator 12. This insulator may be supported on a suitable standardor post 13 mounted in any suitable fashion in the bottom of the casing 1 as shown at 14. The heating element 10, wires 11 and post 13 are preferably of the same material, or if of d fferent materials they will have certain char acteristics in common, all of which will be brought out hereinafter.
The terminals 15-and 16 of the heating element 10 extend to the outside of the casing 1 and are provided with collars 17 of insulating material such as pyrex, for example, annealed to the projections 18 on the bottom of the casing l to provide a hermetic seal.
As above pointed out one of the objects of my invention is to provide a heat exchanger which is capable of operating practically instantaneously. To this end, therefore, I employ materials for the heating element 10, wires 11 and post 13 which are capable of being heated to high temperatures without detrimental deterioration, and inasmuch as the tubing coils 7 surround and are in close proximity to the heating element, an ideal construction is provided for absorption by the coils '7 of the radiant heat from the heating element. A material which I have employed successfully for the heating element '10, wires 11 and post 13 is tungsten, which is capable of operation at high temperatures without detrimental deterioration. For example, in actual practice and employing tungsten as the heating element, I have successfully employed a 3000 watt current at 110 volts carrying the temperature of the heating element to 5000 F.
The casing 1 is exhausted of air and, as above explained, hermetically sealed, and inasmuch as the heating element and the coils '7 are incapable of liberating injurious gases during operation of my device or apparatus oxidation and hence destruction from this cause of the heating element and tube 5 is successfully avoided.
In addition to the foregoing I may further increase the efliciency and prolong the life of the apparatus by placing an inert gas or gases in the casing 1. Such gases which may be hydrogen, nitrogen, argon, for example, not only act as a heat conductor for conducting heat from the heating element to the coils 7, so that the coils are heated by conduction as well as by radiant heat, but convection currents are set up further to assist in the heating operation. Finally by employing an inert gas in the casing thereby creating a slight pressure therein I provide a construction where the heating element is not operating in a vacuum and hence evaporation of the heating element is retarded, and its life prolonged, and inasmuchas the gas employed is free of oxygen I am able to make use of the same with its attendant advantages without detriment to the heating element.
It will be appreciated from all of the foregoing that I have provided a heat exchanger so constructed as to enable the same to be operated most efficiently and at high temperatures for continuous and practically instantaneous heating of the water, or other liquid being treated, for the continuous generation of superheated steam at substantially atmospheric pressure, all without sacrifice of the operating life of the heating element.
As a practicable demonstration of the merits of my device, I have-successfully operated a device, constructed substantially as above described, probably thousands of times, and produced steam at 400 to 600 at substantially atmospheric pressure, (superheated steam) from water at a temperature of around 50 to F. in not over three seconds and without any apparent drop in the eificiency of the apparatus 01 deterioration of any of the parts thereof.
