CONDENSER P11313.

Application led May 13.

This invention relates to condenser pipes and more particularly to condenser vpipesA of the Vtype employing internal corrugations for breaking up the vapor stream within the pipe to prevent passage through the pipe of a core of uncondensed vapor which has not come in Contact with the walls ofthe pipe.

An important object of the invention is to produce a device of this character having a plurality of drainage pairs wherein the inner walls of the pipe is straight, preventing pocketing of the'condensed liuids, these drainage pairs corresponding in number and arrangement to the facets of the pipe flange so that any particular facet may be upwardly disposed and still a proper drainage path provided.

A further object of the invention is to produce a device of this character which may be readily manufactured and in which a maximum radiation surface is provided.

These and. other objects I attain by the construction shown in the accompanying drawings,wherein for the purpose of illustration is shown a preferred embodiment of my invention and Whereinz Figure l is an end elevation of a condenser pipe constructed in accordance with my invention;

Figure 2 is a fragmentary side elevation thereof; .f

Figure 3 is a section on the line 3 3 of Figure 1;

Figure 4 is a section on the line 4.--4 of Figure 2;

Figure is a section on the line 5--5 of Figure 4.

Referring now more particularly to the drawings, the pipe consists of alternate polygonal and round sections 10 and 11, the sections 10 being in the present illustration disclosed as rectangular. These sections may be made with any suitable number of sides, but the number of sides employed should correspond with the number of sides upon the coupling iange 12 provided at the end of the pipe. 'Ihe internal diameter of the round sections 11 is the same as the inscribed diameter of the polygonal sections 10 so that a section taken along sections of the corresponding sides of the polygonal sections will provide a straight Hat wall 13 upon the interior of the pipe along which fluids may travel. It will, of course, be understood that a polygonal section having an even number of sides must be employed,

so that when'an upper facet 14 the flange aries. i

is horizontally arranged'a diametrically op-k posed lower facet l5is likewise horizontally arranged.

The interior angles 16 between ad]acent sides of the rectangular section are rounded,

as'illustrated, so that no pocket is formed in which condensed fluids will tend to' `collect and so that all of these Vcondensed fluids will be directed toward the path provided at thel bottom of the pipe for their passage. The i perimeter of each rectangular rsection is formed with a projecting rib or vane 17 to increase the cooling surface'provided. It will rbe noted that in alignment with the corresponding included angles of the polygonal sections a vsinuous wall 18 is produced which will tend to keep the passing vapors in continuous motion to break up the core of the vapor stream. There will be walls 18 corresponding in number to theincluded angles y16 of each polygonal section and their combined action upon the vapor stream will tend to very thoroughly break the .stream up, bringing all parts of the vapor into contact with the walls ofthe pipe.

It will7 of course, be understood that in referring to rectangular and round sections,

reference is had to the construction of theY 1. A condenser pipe formed interiorly to produce alternate round and polygonal sections. the polygonal sections having corresponding sides thereof disposed in common planes tangential to the round sections whereby the round and polygonal sections combine to produce wall sections correspond-A ing in number to the sides of the polygonal sections in which the points of tangency and the mid-points of thecorresponding sides of the polygonal sections line in the sam straight lines.

2. A condenser pipe formed interiorly to produce alternate round and polygonal sections, the polygonal sections having corresponding sides thereof disposed in common planes tangential to the round Sections wherebyv the round and vpolygonal Section combine to produce wall sections corresponding in nuniber to the sides olf the polygonal sections in which the points of tangenoy and the .mid-points of the corresponding sides of the polygonal sections lie in the saine Straight linee`r the exterior of the pipe being provided in alignment With each polygonal seotion with an outstanding cooling rib.

A Condenser pipe formed interiorly to produce alternate round and polygonal seotions, the polygonal sections having corresponding sides thereoic disposed in coininon planes tangential to the round sections whereby the round and polygonal sections combine to produce wall sections, corre-v sponding in number to the sides of the polygonal sectionsin which ,the points of tangeney and the luid-points of the corresponding sides of' the polygonal Sections lie Sections in which the points of tangenoy and the mid-points ol" the Corresponding sides of the polygonal sections lie in the saine straight lines, jthe connections between those 'portions of the sections lying between Said points providing a sinuoue Wall.
