MODINE, OF RACINE, WISCONSIN, ASSIGNOR T MODINE MANUFACTURING COMPANY, OF RACINE, WISCONSIN, A CORPORATION OF WISCONSIN HEAT' EXCHANGE 'UNIT Application led August 26, 1929. Serial No. 388,494.
My invention relates generally to heat ex` change devices and, while suitable for either heating or cooling systems,- has to do more particularly with apparatus of the type referred to which is particularly adapted for heating a factory or other enclosure used for industrial purposes.
An object of my invention is to provide a heating unit which will be` adapted to project a current of heated air into an enclosure and is so designed as to permit thermal expansion and contraction of the. heating elementsfwithout danger of injury to the device, and consequent leakage of heatingiiuid. Another object is to provide a device of the class described which is adapted to be so mounted that the heated air may be projected in any desired direction.
Another object is to .provide improved means for securing a radiator tank to auid 'conduit so as to obtain a luid tight joint To this end, my'invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims. f
Referring now to the drawings forming part of the specification and illustrating a preferred embodiment of the invention;
Fig. 1 represents a front elevation of a de- .vice embodying my invention;
Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1v; i
Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1; on a slightly enlarged scale.
Fig. 4 is a sectional view taken on the line 4-4ofFig.3;and
F ig.- 5 is a sectional view taken onthe line 5 5 of Fig. 3.
The invention herein shown and claimed `is also disclosed in part in my Patents, No. 1,800,842 issued April 14, 1931, and No.v
1,836,271 issued December 15, 1931, another species of the invention bein shown in an application filed by me, erial Number 384,203.
In the preferred embodiment illustrated, thenumeral 1 indicates generally a heating unit adapted to be mounted in any convenient manner. In the embodiment disclosed, the heating unit 1 is supported from the top and bottom by means of nipples 2 and 3 which respectively connect With the supply and return lines of the heating system. These l nipples are rotatably secured to pipe unions v4 and 5 as shown in Fig. 1. It will be understood that the pipe union 4 is connected to a pipe 7 leadingfrom any suitable source (not shown) of heat exchange fluid, such as steam, hot water, or the like, while the lower pipe union 5 is connected to a conduit 6 for carrying off the heat exchange fluid.
The heat exchange means comprises, broadly, an upper tank 9 and a lower tank 10 communicating with each other by means of spaced tubular members 11. Secured on the tubes 11 and extending tranversely thereof are vanes or fins 12. It will be understood 'that the tubes and vanes are formed of any suitable material having a high heat conductivity, and are preferably of thin sheet metal.
A frame member 13 having a fluid conducting passage 14 therein is connected to the nipple 2 by means of screw threads or othere suitable means. The tank 9 is secured to the frame member 13 by means ofv headed bolts 15 screw threaded into spider like members 16 Aformed integrally with the frame member 13 in the passage. These bolts extend through spiders 17 which have apertured heads which are located-in apertures 19, the latter of which are provided in the front wall of the tank 9. lhe leg portions of the spiders are connected at their opposite ends by a ring member'21 having an annular fiange 20 which seats against the rear wall of the tank 9. The passage between the tank 9 and the passage 14 is completed by means of a nipple 21 which is constructed to provide a iiuid tight joint between the tank and said passage 14. This nipple is inserted into the ring 21 and since one end of the bolt 15 is secured in the spider 17 of the frame 13, rotation of the bolt 15 in one direction will cause the spider 16 to be drawn against the nipple 21 forcing the wedge shaped end of the nipple into the aperture 23 provided in said frame member.
It will be noted from Fig. 3 that the lower portion of the tank 9 is open and that both the front and rear walls 24 and 25 of the tank have their edges respectively grooved so as to receive the opposite longitudinal edges 26 and 27 of a header plate 33. The ends of the tubes 11 are secured to the tank 9 by means of solder or other suitable means. It will also be apparent that the construction of the lower tank 10 is substantially similar in this respect to the upper tank 9.
The frame member 13 is formed to provide a rearwardly extending bracket 28 which has a bracket 29 secured thereto for supporting a motor 30. This motor may be of any suitable design, preferably electrical, and has a fan 31 attached to the shaft 32 thereof.
Side plates 33 and 34 having one end thereof secured to the frame 13 extend downwardly therefrom to a suitable distance beyond the lower portion of the tank or header 10. These ends of the side plates are connected with an` end piece or closure 35 having the upstanding anges 36 and 37 provided at its opposite longitudinal edges. It will be noted that a space 38 is provided between the header andA the end plate to permit movement of this header relatively to the end plate to compensate for expansion of the tubes 11 and that the iange 36 frictionally enga-ges the outlet header 10. A casting 39 is connected by means of the bolts 40 with the end plate and this casting has a fluid passage 41, to which the outlet nipple 6 and pipe connection 42 are connected to thereby provide means for conducting the exhaust heat exchange fluid from the tank or header 10. The pipe conneetion generally designated 42 includes a threaded boss 43 formed upon the rear wall of the tank 10 which has a nipple 44 threaded therein; this nipple is connected by means of a coupling 45 with the tube 42. This tubular member may be formed of brass or of other suitable flexible material and is connected at its opposite end by means of a coupling 51 with the passage 41 provided in the casting 39 which provides a bracket to assist in the support of the device generally designated 1.' As will be noted from Fig. 3, the bracket 39 is substantially Lshapedin section and communicates with the outlet or drain nipple 6. Numeral 53 indicates a plug for closing a drain opening for the passage 41 of the casting 39. The header 10 is constructed tocorrespond with theJ header 9 in that it is provided with longitudinal recesses provided in the side Walls thereof for the reception fianges provided upon the closure 55 thereof.
In operation, the heating unit is mounted in the manner described above with the conduit 2 connected to a suitable source of heat exchange fluid (not shown). The motor 30 is connected to a suitable source of electrical energy (not shown). It will be obvious that when themotor and fan are set in operation, air will be drawn into the lheat-ing unit from the rear thereof and forced past the tubes 11 and the fins 12. When the tubes 11 become heated, they obviously expand lengthwise, thus moving the tank 10 downwardly. Such expansion is permitted by means of the space provided between this tank 10 and the member 35. Furthermore` the fact that the tubular member 42 is flexible will permit relative movement between the coupling 45 and the coupling 51 when abending stress is applied to the tubular member 50. It will further be noted that theheating unit may be rotated about an axis represented by the nipples so that-the beate?. alr may be directed into any l portion ofthe room desired.
By means of the peculiar connection between the upper tank 9 and the frame member 13 a fluid-tight connection is obtained without the use of gaskets, solder or the like, which will remain satisfactory over long periods of time. It is obvious that considerable pressure may be applied to the tank by means of the bolts 15 so as to wedge the nipple 21 very securely into the apertures of both the tank and the frame member without danger of injury to the tank.
Furthermore, it will be obvious that the casing member 35 serves as adrip pan to catch vany possible drippings of oil from the fan ory motor, and also provides means to catch any of the heat exchange liquid from the tubes or tanks, which might result from leakage between the tubes and the headers,
or in ease the device were used for cooling rather than heating, might be the result of the condensation of atmospheric moisture on the outside of the tubes or other members? It is also manifest that the member 39 provides a bracket which assists to support the device and that the member 13 performs this function and in addition provides means for supporting the motor and the fan.
Having thus described the invention, it is obvious that changes andl modifications may be resorted to without departing from the spirit of the appended claims forming a 1 part thereof. What I claim and desire to cover by Letters Patent is:
