Referring to Fig'. il, the epperzitns sliown comprises e .liquid rlieostet L sin electrolytereoiitaining reservoir Q, e pump :iuXiL Jury cooling; apparatus l end e tim 5.
The rlieoetat l ie provided with a bot,- toni discharge opei'iiiig S in .vliieli is placed a tubular combined discharge :intl regulating)l velvet) tiret Ais licliipteol to be raised and lowered in position by any Suitable ineens (not Shown) for tlie purpose of closing the dieflierge opening' S unil fixing tlie lieiglit oil? tbe electrolyte which ie eoiitinoouely Supplieil to lie rlieoszzt through en. inlet pipe l0. liie epee-nie eolie' ,notion tbe moi able discharge one. regulating valve not materiel to my present invention except ne it contri )Utes to tbe perlfornizmee of neeessary functions; in the operation of the System es e Whole, and Aany other sui-ble (levieee .tor performing similar functions may be employed. The rlieostiit l is located directly above alie .reservoir 2 :intl the eleotrolyte flowing tlironfli it is diseliergecl therein.
The pump 35 cooling apparat-us l and tan 5 :ire also merely illustrative o' any forni et devices for performing their respective (luties. The pump 3 receives eleetrolyte vtroni the reservoir Q tlirongli e onction pipe l1 and forcee Said electrolyte through 'the `inlet pipe l0 to tlie rlieofstet l.
taining tank l having a plurality of plates`IAV l5 that are alternately secured to opposite sides thereof enti are ine/lined in zielen/n 'Ward direetioink fthe length thereof being M to provide a spese between the free enfle thereof and :uljaeent Sides of the tank. A pipe i6 ooininnnieetee with the upper enel of the tank 14; above the upper plete 'l5 :mtl is connecter?. to the mein inlet l() edineent to the dieelierge side tliepninp 8. A Suitable rlellecting barrier l?, 'which tney the pipe 16, projects into the inlet gpiie l() just above the point of connection of the pipe 16 therewith, although it may not be necessary in all cases. The object of the delecting barrier 17 is to partially obstruct the pipe 10 and to cause a building up of pressure at thev lower end of the pipe 1G whereby electrolyte isforced upwardly in the tank 14. The lower end of the tank 1l is connected to the suction pipe 11 by means ot a pipe 18. Moreover, the fan 5 communicates with the lower end of the tank 1l through a pipe 19 for the purpose of introducing thereto a cooling medium, such vas air. An outlet 2O is provided at the top, of the tank 14 for permitting the escape of heated air and vapor.
Assuming the apparatus to occupy the positions shown and the pump 3 and fan 5 to be in operation, the electrolyte within the reservoir 2 is drawn into the pump 3 and forced upwardly, the main body thereof being delivered through the inlet pipe 10 to the rheostat 1, while a relatively small volume is by-passed through the pipe 16 to the cooling apparatus al.
When the rheostat 1 performs its function of absorbing electrical energy in accordance with customary practice, it will be understood that the energy is transformed to heat which is absorbed by the continuous floW of electrolyte. A portion of the heated electrolyte is continuously delivered to the upper en'd of thc cooling apparatus 4 from whence it flows in a zig-zag path down across the several plates 15 andl is thus brought into contact with the forced ventilating air which rises between said plates and is permitted to escape through theout-` let 20.
ln this manner a relatively large amount ot' heat is dissipated continuously from the small portion ci' the electrolyte that traverses the cooling apparatus 4, so that the electrolyte which is returned to the main circulating system through the pipe 18 is of comparatively low temperature, and, in
mixing with the mainbody ot' circulating.
electrolyte maintains it in a sulliciently cool tendit-ion to insure proper operation.
ltL is seemytherefore, that the cooling apparatus ocbupiesvery little space and is capable of dissipating heat at a rapid rate to maintain the main body of electrolyte at a temperature within operating limits.
Reference may now be had to Fig. 2, which discloses apparatus of a similar nature to that already set forth, with the eX- ception that the cooling apparatus Il is located at a kyheight suiiicient to permit the return pipe 18 to carry the cooled electrolyte by gravity into the inletl pipe 10, Thus, the heat of a part of the circulated electrolyte is directly dissipated in the cooil ing apparatus and the cooled electrolyte is delivered to the inlet pipe 10 and vmixed with the main body of electrolyte before being` delivered to the rheostat 1. -f
Obviously my invention may be embodied y in apparatus, the structural features and ar- Y rangement of parts of which differ myxiteri- 70.l ally from those herein Set forth, and Ltherefore, desire that only such limitations shall be imposed as are indicated in the appended claims.
