CONDENSER ,ron ICE mncrmvns.

. Application filed J'anuary 8,. 1927. Serial No. 159,881.

In any mass of pipes laid rather closely together, in directing currents of air against such a mass, many conflicting air currents are set up, with the result that a great deal of the efi'ectiveness is lost.

In my invention I make use of the natural stream lines principle, by creating an air suction past a refrigerant receiver, length ing air currents which enter from7the top of A base through an orifice. A pipe leads from 'the discharge side of the compressor to a gas receiving tank within the base and from which extend a multiplicity of pipes whlch connect at their other end to a condensate receiver. An air intake port is located at this end of the base.

' In Figure 2 of Sheet 2 is shown a horizontal cross section of a hollow base containing a gas receiving tank as in Figure 1, and leading from this are lines of pipe consisting of straight runs with reverse bends; but having the straight runs crosswise of the base.

At the other end these pipes connect to the condensate receiver. The base in this case also has a suction air intake located next to the condensate receiver. In Figure 1, I have shown a base 1 on which is mounted a motor 2, direct connected to a coupling 3 and a fan 4, and through the shaft 5 to a pump 6. The pump 6 shows a suction port 7 and in dotted lines the discharge port 8 to which Is connected a pipe 9 that attaches at its lower end to a tubular manifold 10.

Branching from the manifold 10 are shown four (4) lines of pipe 11, other lines of pipes supposedly lie back of those shown.

These pipes enter at their other'end the receiving chamber 12 where liquid refrigerant is caught after condensation. Surrounding the fan and the pump is a casing 13 which rests on the base. At 14 is a rectangular opening in the top of the base which extends to nearly the width of the casing 13, and

through which air is drawn. At 15 is an opening in the sides of the base of suflicient size to pass all theair that the fan is capable of throwing. It will be observed that as the fan 4 is rotated in a right hand direc- 6t tion it will give rise to an area of low pres sure on the pump side, this will result-in air entering the open portion of the base at 15and 1t Wlll pass in the direction of the arrows 16, longitudinally with the pipes 11,

out through the opening 14 and finally out of the contracted opening surrounding the fan. The compressed gas coming from the pump 111 tube 9, after entering manifold 10 will then be distributed to the pipes 11, following direction of arrows 20, and as it condenses Wlll pass into the container 12, thus setting up a current within the pipes in a I reverse direction to the. passage of the air through the base.

k On Sheet 2, Figure 2, is shown a top view of another arrangement of pipes, but in WlllCh the principle governing is the same.

I have used the same numbers as on Figure 1, except that the opening 17 in mani fold 10 and the dotted lines 18 show the position of. the rectangular orifice 14. In both figures, a plate 19 extends from the manifold end of the base to the side opening 15 and underlies the pipes, in order to confine the air current more closely to the channel 'in whlch the pipes he. In Figure 2 the pipe 9 is supposed to enter the manifold 10 at 17, the arrows 20' show the direction of the flow of the gas 1n the pipes 11. In this case each pipe has a number of reverse bends,

but the gas becomes successively cooler as I it approaches the opening 15, and finally enters the container 12. I have, for clarity,

only shown two runs of pipe as they lie one above the other.

The air current shown by arrows 16 is thus really in reverse direction to thegeneral direction ofthe gas within the pipes, and after traversing the pipes flows upward through the opening 14 shown by dotted lines 18 into the chamber surrounding the pump. By these arrangements a decided gain in efficiency 1s efl'ected, as it produces so rapid a current of air past the condenser pipes that 1 a much smaller length of pipe is necessary to produce an equivalent amount of cooling, and as thecoldest air in the systems passes in at the container end of the line, and the temperature at this end establishes the 11 amount of ressure that must be carried, it thereforeefiects a double economy in cost' of construction and in operating expense.

I hereby make reference to an application Serial No. 159,882, filed Jan. 8, 1927 for a patent for method of cooling air cooled Iefrigerating machines.

Therefore I claim:

1. The combination with an air conduit having admission and discharge ports; of means for effecting the passage of air into the admission port, through the conduit and through the discharge port; a gas receiving chamber; a condensate receiving chamber; piping Within said conduit extending substantially along the path of and following through said conduit and connecting said chambers; said chambers and the piping connecting them being arranged to direct the flow of gas and condensate to the condensate receiving chamber oppositely to the direction of flow of air along the piping; and a pump connected with the gas receiving chamher to force gas thereunto and into the piping connecting the chambers.
