METAL TUBING..
Application filed May 11,
This invention relates to improvements in tubing and more particularly thinv metal tubing, sucli as used for refrigerating and other heat or cold transferring purposes.
The main object of the invention is to provide a tube lso constructed that it will be divided into two or more separate and distinct passages so that gas and liquids or different gases or different liquids may be lio circulated through a single tube without mixing or interfering one with. other.
Another object of the invention is to make the tube of several independently formed sections which when applied together to complete the tube will provide the separate and distinct passages through thetube. Another object of the invention is to provide means for holding the tube sections tightly together and at the same time form.
extended radiating surfaces on the exterior of the completed tube.
The invention consists further in the mat ters hereinafter described and claimed.
In the accompanying drawings- Fig. 1 is a side view of a spiral lin tube constructed in accordance with my invention' Fig. 2 is a section through Vthe tube on line 2-2 of Fig. l; l
Fig. 3 shows another form of the tube; and
` Fig. 4; is a section taken on' line fir-4 of Fig. 3.
In Figs. 1 and 2, the tube is made of two half round seamless thin metal longitudinal sections 1, 2. The sections extend the full length of the tube and are substantially alike by being drawnI over a die of the desired size andshape. s After the sections are made, they are placed together with their diametric fiat walls 3, 3 in contact so as to orm a complete round.
The two sections 1, y2 so assembled are then run through a spiral fin applying machine and a relatively thin metal fin 4 is,
tightly wound on and about the outer` circumference of the assembled sections in a spiral form. The fin 4, while or after bein applied, is soldered to the sections and,
l in addition to holding them tightly `together,
also provides the tube with extended radiating surfaces on the exterior of thetube. YThe finished tubes may be used straight er the may be bent inl any shape desired.
ith the tube made of two independ- 1928. Serial No. 277,067.
entl formed sections 1, 2, two separate and distinct longitudinal passages 5, 6 are provided in the tube for as or liquids, the c ontactin diainetric wals 3, 3 of the sections dividing the passages throughout the entire length of the tube.
In Figs. 3 and 4, I have shown how a tube may be made of independently formed sectionsto provide three separate and distinct pasages extending throughout the length of the tube. As illustrated, the tube is made up of three segmental sections 7, 8, and 9, each being approximately one-third of the circle of the completed tube. These sections are preferably made alike by being drawn over a die of the desired size and shape, and are then assembled with their radial flat Walls 10, 10 in contact and meeting at the center of the tube to complete the round. p l
The sections 7, 8, and 9 when so assembled are then run through a fin applying inachine, and a metal fin 11 is tightly wound on and about the sections andsoldered thereto to hold the sections together and complete the tube with its extended radiating surface,
as before. The sections 7 to 9 provide the three passages for the complete tube, said passages being divided throughout the length of the tube by the contacting'radial walls 10, 10 of the sections.
The number of passages required will depend on the number of sections of which the tube is formed, and I do not wish to limit my invention to any particular number of passages, nor to any particular manner of makingthe passages in conjunction with a multiple passage tube with an extended radiating surface or surfaces on the exterior o f the completed tube. Moreover, the fins employed may be other -than in iral form. Individual fiat ins could be use or gang ns may be used with an assembly of. my improved tubes, all without departing from the spirit and scope of my invention. l
There are many places where my improved tubes may be used to advantage. In soda-water cabinets, where two temperatures are required, one for the ice-cream and the other for extracts and brick cream. In direct expansion coils in connection with a brine for hold-over, the brine may be placed in one passage and sealed up, and the refrigerant circulated through the other passage. The tube may be used. in making an evaporator, using brine in one section of the tube. As a cooler for water for drinkin fountains, the refrigerant may be circulate through one section of the tube and the drinking wat-er through another. Other uses will be apparent to those skilled inV the art to which my invention pertains.
I claim as my invention:
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 distinct passages for the tube, and fins about the sections to hold them together to them together tocomplete the tube and to rovide extended radiating surfaces thereor.
5. A circular tube consisting of separately ing a portion of the circle of the tube and providing a separate and distinct passav'e therefor, and a spiral fin wound about t e assembled sections for holding them together and to provide extended radiating surfaces therefor.
6. A circular tube consisting of two separately formed half round sections to provide separate and distinct passages for the tube, said sections being applied with their flat surfaces in contact to complete the circle of the tube, and fin means about the tube for holding its sections together and to provide extended radiating surfaces therefor.
7. A circular tube comprising a multiplicity of longitudinally extending segmental sections .independently formed to provide separate and distinct. passages for the tube, said sections being applied with their flat surfaces in contact to complete the circle of the tube, and a spiral fin Wound about the 1formed longitudinal sections, each constitutoutside of the tube for holding the sections
