CARL HERMANN JAEGER, OF LEIPZIG-PLAGVJITZ, GERMANY.
TU BULAR HEAT-EXCHANGE APPARATUS.
To alt ioLoi/nt may concern.'
Be it known that I, CARL HERMANN JAE- oiiii, engineer', a subject of the King of Saxony, residing at Leipzig- Plagwitz, irei-- many, have invented new and useful Improvements in Tubular Heat-Exchange Apparatus, of which the following is a specification.
The present invention relates to cooling apparatus more especially to cooling apparatus ferro-tary compressors or blowers which consist of curved cooling pipes connected at their ends to water chambers by means of which the cooling agent is fed to or discharged from the cooling device.
One drawback to the known devices of the kind is the fact that owing to the different lengths of the pipes the resistance offered to the cooling agent is different in each of the several pipes. As a consequence the quantity of cooling fluid passing through the several pipes and the cooling effect of the several pipes varies to a large degree.
The present invention has for its object to obviate this disadvantage by providing a plurality of tubes of different lengths and connecting sanie in parallel so as to form groups, which groups are again connected in series so that the resistance of the various groups is approximately the saine.
'In the accompanying drawings, Figure 1 is a section of one form of tubular heat exchange apparatus embodying my invention; and Fig. 2 is a partial sectional view on the line II-II of Fig. l.
The casing of the heat apparatus consists of two parts l and 2, which may be bolted together in any desired manner.
The cooling device comprises also two parts, each part consisting of an admission pipe 3 for the cooling fluid, supply easing or header il, a receiving casing 5 and an exit pipe G. The casinos l and 5 are fixed to the lower and upper casing sections l and 2 by means of the bolts 7. The water enters through the pipes 3, and passes into the casings 4l, thence through the inner portion 4a of each casing into a pipe 10 of a small radius which leads into the inner portion 5EL Specification of Letters Patent.
Application filed April 17. 1911.

of the casing 5. The water then returns through a number of intermediate pipes 1l 'into the outer portion of the casing 4, and
then flows back through a greater' number of outer pipes 12 into the outer portion of the casing 5, and is discharged therefrom by the pipes 6.
In practice the air to be cooled is drawn or forced into the casing in any suitable manner.
I claim y l. Tubular heat exchange appa 'atus comprising a plurality of tubes of different` lengths, and end chambers connecting tubes of one length with a greater number of tubes of greater length; substantially as set forth.
2. rlubular heat exchange apparatus comprising a plurality of groups of tubes of different lengths, and end connections connecting said groups in series, the number of tubes in the various groups from one end of the series to the other being increased in accordance with the increase in length of the tubes in that group as compared with tubes in another group; substantially as set forth.
Tubular heat exchange apparatus comprising a number of curved tubes of different lengths arranged so that the longer tubes partly surround the shorter tubes, and headers connecting the tubes in such a manner as to constitute a plurality of groups with the groups connected in series any group of longer tubes comprising a greater nuinber than any group of shorter tubes; sub-V stantially as set forth.
1l. Tubular heat exchange apparatus comprising two headers to which are connected y a number of tubes of gradually increasing length, partitions in said headers so arranged that any group of tubes is connected in series with a group of tubes of greater length and of a greater number than itself; substantially as set forth.
Tubular heat exchange apparatus comprising a plurality of longitudinally curved or bent tubes of different radii concentrically arranged, headers connecting correspending ends of the tubes Vand partitions In testimony whereof I have signed my in the headers so arranged as to divide seid nume to this speoieation in the presence of tubes into groups of parallel members with two subscribing Witnesses.
groups Connected in series, groups of tubes CARL HERMANN JAEGER. of smaller radius comprising fewer numbers Witnesses: of tubes than groups of tubes of greater ALBERT R. MORAWETZ,
radius; substantially as set forth. RUDOLPH FRICKE.
