HEAT EXCHANGER Filed sept. 25. 193e INVENTOR ?atented ug. VJi7, 1937 09ans UNITED .STATES PATENT, OFFICE naar examinons,
Joseph A. Coy, Tulsa, kla. Application september 23, 1936, serial Ne.v 102,233 'z claims. (c1. 25a-24s) The invention relates to heat exchanges, particularly of the type which is moved from place to place, and wherein the units .are relatively long, and has for its object to provide the heat exchanger with a floating head and floating support means for the tubes slidably connected to the side channels of the frame in a mannerl whereby when the heat exchange unit is hoisted,
Aguanti contraction, incident to temperature, but
preventing outward spreading of the channels.
A further object is to form the support from spaced bars b etween which the tubes are disposed and to connect the bars at their ends so that they V will slidably move within theframe channels, andv to provide U-shaped brackets, arching the chanbeing understood that changes-in the precise em bodiment of the invention may be made within y the scope of what lis claimed without departing from the spirit of the invention.
In the drawing:
Figure 1 is a top plan view of the heat exchange j unit. Figure Z'is a side elevation of the unit. Figure 3 is a vertical transverse sectional view 5 through the unit, and through a modified sup port.
l Figure 4 is a vertical transverse sectional view through one side of the unit showing the form of slidable connection between the tube support and the channel shown in Figures 1 and 2.
Figure 5 is an enlarged side elevation of thev central portion of the unit showing the support connection shown in Figure 4.
Figure 6 is a detail perspective view of one end.
of the modified form 0f tube support shown in Figure 3 showing its connection to one of the channels.
Referring tothe drawing, the numeral I desighates the stationary head of the heat exchanger,
' to the ends of which are connected in the usual manner, by meansof bolts 2, the side channel bars 3 of the Aunit. Connected to the stationary head I is a plurality of tubes 4, which are relatively long, and which are parallel. The tubes 4 extend longitudinally of the device and are connected to a floating head 5 which allows the tubes 4 to expand and contract under heat and cold as shown in dotted lines in Figure 1. Devices of this character are usually extremely long, particularly'where used in the oil industry and are subject to a great deal of handling. It has been found that in hoisting devices of this character, which weigh several tons per unit, if hoisted by one of the channels 3, they become bent or distorted, and to obviatethis dimculty the tubes 4 are provided with tube supporting members 5a,
through which the tubes extend, and which have their ends slidably connected to the side channels 3, so that they may slide during expansion and contraction, but at the same time prevent spreading of the vchannels during a hoisting operation and distribute the hoisting strain throughout the unit during the edge hoisting thereof. The number of tube suports 5a may4 vary, however two -are shown for purposes of illustration, and one will be described in detail. Y
- Referring tothe form of device shown in Figures 1, 2, 4 and 5, in this form the tubes 4 are clamped between fibrous members 6, preferably formed of woo-d and the fibrous members 6 are disposed between spaced bars l, which are drawn together against the fibrous bars 6 by bolts 8 for clamping the support as a whole on. the tubes so the support will move with the tubes upon expansion and contraction, thereby obviating-the wear on the tubes incident to scale formed thereon and the tubes dragging through the support.
The ends of the clamping bars 1 terminate in guide portions 9, connecting the bars at their ends, and which guide portions are disposed within the channels 3L The guide portions 9 are slidably connected to the channels 3 by cap bolts l0, which extend loosely through elongated apertures Il4 in the channels 3, therefore it will be seen that as the tubes 4 contract and expand, the supports 5abodily move with the tubes and that the sliding engagement of the ends of the supports within the channels, will allow freedom 1 of movement of the supports, however the cap bolts Il) will positively prevent spreading of the difficulty is overcome.
2 i .l I K will distribute the strain throughout the unit.'
Referring to the form of device shownin Figures 3 and 6; in this form the upper and lower bars I have connected thereto the arms I2 of U-shaped brackets I3 which arch the outer vsides of the channels I and allow freedom of longitudinal movement of the tube support during expansion and contraction and prevent spreading of the channels I during a hoisting operation. The U-shaped brackets I3 are connected to the bars I by meansof bolts Il which extend through the arms I2, bars I and clamping strips i. When the bolts Il are tightened the tubes are clamped within the support. The arms I 2 are additionally anchored to the upper and lower bars 1 by means of bolts I 5, which prevent side pivotins and displacement of the brackets I3. Spacers I8 are preferably used to lspace the arms 'I2 upwardly out of engagement with the side channels 3. It will be noted that in both forms play is provided between the slidably engagedA parts, which prevents sticking, incident to expansion, and allows easy movement of the parts.
The upper and lower bars 1 are preferably pro-l vided with tlanges 1a, which brace and stiffe'n the same, and the channels I may .be-braced by transversely extending angle bars I1 bolted thereto. .'Ihe heads I and l are provided with the jusual'fisnged connections Il whereby the heat This has been found to be true even where the tubes are slidably mountedin oversize apertures of wooden blocks, hence it will be seen by clamping the support to the tubes and' allowing the support to bodily move with the tubes, the above Rrom the above it will be seen that a heat exchange unit is provided wherein the tubes are supported so they will not wear during expansion and contraction and that the supporting means v-fo'r theQtubes will also brace the unit frame so that it may;he hoisted by its side without bend- V l ing the side bars and in a manner whereby the strain will be distributed throllhilt the unit.
This is o! decided advantage in the 'oil industry where units are transportedfrom piace to place and assembled, and this necessarily `in stationary head carried by said frame, a floating l head carried by said frame, tubes connecting said heads and adapted to move the floating headupon expansion and contraction and a slidable connection between the floating head and the frame,
'9,090,345 channels during a hoisting operation when the i device is suspended from one of the channels andy said sliding connection comprising headed members extending through elongated apertures in the frame. v
2; The combination with a heat exchange unit comprising a frame having side bars, a stationary head connecting the side bars at one end thereof, and a oating head connecting the side bars at the opposite end thereof, tubes connecting said heads of a tube `support slidably connected to the side bars, said. tube support beiliii' clamped on thetubes to move with the expansionl and contraction of the tube whereby the slidable engagement of the support will be with the side bars.
3. The` combination with a heat exchange unit comprising side channel bars having their channels inwardly disposed, a stationary head connecting said bars adjacent one end thereof, and a floating head connecting said bars adjacent the other end thereof, of a stationary tube support intermediate the heads, and tubes connecting" the heads and extending through the support.'
said support being clamped on the tubes and movable therewith, the ends of said support having slidable engagement within the channels of the channel bars.
4. The combination with a heat exchange unit comprising side channel bars having inwardly disposed channels, heads carried by said channel bars and connecting the same, slidable connections between 'one of lsaid heads and vthe channel bars whereby the said head and bars may move relative to each other, and tubes connecting said heads, of a support for said tubes,
said support comprising spaced bars between which the tubes extend, gripping members between the bars adapted to grip the tubes, means for forcing said bars towards each other and slidable connections between the ends of the bars and the channels.
5. A deviceas set forth in claim 4 in which the slidable connections include headed members carried by the vends of the support bars and extending'through elongated apertures in the channel bars, and forming `a sliding anchored-connection between the support and the channel bars.
6.'A device as set forth in claim 4 in which the slidable'connections include straps carried by the ends of the support and arching the outerside of the channel 4bars and forming means for preventing spreading of the channel bars.
