Patented Sept. 22, 1931 UNITED STATES 'PATENT OFFICE HARRY r. SMITH, or DAYTON, OHIO, Assreiron fro imIGIDAIRE coarom'rromor DAYTON, OHIO, A CORPORATION or DELAWARE REFRIGERATING ArPABATUs Application med march as, 1929. serial N0. 350,711.
This invention relates to refrigerating apparatus and particularly to tubing used in such apparatus for heat exchange purposes.'
l@ arrangement of fluid circuits or passages in intimate heat exchangerelation with each other.
More specifically stated,`it is an object of the invention to provide an improved tube which can be formed. and used mechanically as a single tube, but which has a plurality of independent or hydraulically isolated circuits.
Another object is to provide a tube formed of a number of independent longitudinal sections or tubes whichwhen assembledmake Va unitary circular tube, which can be worked and handled as an ordinary round tube.
Another obiect is to provide improved means for holding the sections together.
Still another object is to provide all of the passages of the tube with a large heat exchange surface presented to the environment of the whole tube.
Further obj ects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the present invention is clearly shown.
In the drawings: V
Fig. l is a side elevation of asection of tubing embodying the invention, and
Fig. 2 is a section on the line 2-2 of Fig. 1.
Referring to the drawings '10 designates generally a tube which is formed of any suitable number of longitudinal sections or tubes f such as 1l and 12, made of thin metal of good thermal conductivity such as the drawn copper commonly used for heat exchange tubing in refrigerating apparatus. Each of the sections or tubes l1 and 12 is shaped in theiform of a portion of a circle so that when the tubes are placed together they form a'complete circle. For example the tubes 11 and 12 shown in Fig. 2 are sectors of a circle each being substantially a semi-circle. The fiat sides 13 and V14 of the sector tubes are placed together and the tubes are fastened together by a member or members 15 whichsurround the come plete tube 10. This member or members preferably constitute heat exchan e fins or linning and may be formed of in ependent tins placed'about the tubes, Aor as shown in the drawings, it may be a thin copper strip wound edgewise to. form a helix.. `VThe parts described may be assembled and held together in any desired manner, for example the tubes -11 and 12 may be laid together, the lin 15 wound about the assembly and the whole dipped in molten solder. This forms a strong mechanical bond between the sections or independent tubes and the fins, and rovides a vgood thermal contact between t e several used. However, the construction of this tube l by using av lurality of independent smaller tubes provi es a number of separate passages or circuits for the circulation of any desired fluids. Obviously the circuits or vpassages are hydraulically isolated but are in intimate thermal relation with each other so as to be substantially identical thermally.
While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.
What is claimed is as follows:
1. A tube consisting of separately formed longitudinal sections providing separate and distinct passages for the tube, and means for holding the sections together to complete the tube and to provide extended radiating surfaces on the exterior thereof.
2. A tube consisting of separately formed longitudinal sections providing separate and les vdistinct passages for the tube and fins about the sections to hold them together to complete the tube and to provide extended radiating surfaces therefo 3. A tube consisting of separately formed longitudinal sections providing separate and distinct passages for the 'tube `and a fin spirally wound about the sectionsto hold them together to complete the tube and prom vide extended radiating surfaces therefor.
4. A. circular tube consisting of separately formed longitudinal sections, each constituting a portion of 'the circle of the tubeand providing a separate andA .distinct passage therefor, and fins about the' sections to hold them together to complete the tube and to provide extended radiating surfaces therefor.
5. A circular tube consisting of separately formed longitudinal sections, each constitut- .20 ing a portion of the circle of the tube andproviding a separate and distinct passage therefor, and' a spiral iin wound about the assembled sections for holding `them together l and to provide extended radiating surfaces I Y. g5 therefor.
6. A circular tube consisting of two se aratelyformed half round sections to provide separate and distinct passages for the tube, 4saidsections being applied with their flat v surfaces in contact to complete the circle of the ltube, and fin means about the tube for holding its sections together and t provide extended radiating surfaces therefor.
.7. A circulartube comprising a `multi` p plicity of longitudinalllyvextending seg- ...mental sectionsv independentlyl formed to ''povide separate and distinct passages for the tube, said sections being applied with their flat surfaces in contact to complete the o circle of the tube, and a spiral lin wound signature. r-
about the outside of the tube for holding the sections together and" to provide extended radiating surfaces therefor. In testimony whereof I hereto aix my HARRY F. sMrrn.'
