Thetonere atiomo-fs: the raboveadescribedcconstructiomisi as the tank [2 finds ingress to the steam passage l6 through the aperture 20. During light loads of the engine the volume of steam generated is relatively small. This steam enters the lower ends of the inclined set I l and flows upwardly therein. The direction of air flow between the tubes in this form of construction may beassumed to be upward and this-direction may be, induced ther-' mally or created by a fan or'blower; When a small amount of steam is supplied to the lower ends of the set of tubes l I, this small amount will quickly condense before the steam progresses any great distance up these tubes. Particularly is tank 25, the level of the water being indicated by the dotted line 81. Similarly condensate from i the lower bank isreturned through passage 10 this true when the temperature of the cooling air is very low. The condensate which cools on the I walls of the tubes of the lower set drains back in a counterflow direction with respect to the flow of steam and is collected by the partition l4 and returned to the water space of the tank 12 through one or more apertures 2|. Under these circumstances even if the air passing across'the tubes is very cold and is much below freezing, as the'condensate is continually flowing back counte'rcurrently to the direction of the flow of steam there is no danger of this condensate freezing in the tubes inasmuch as it flows back out of the tubes as soon as itis deposited. As the load increases and'the amount of steam supplied to the tubes increases the steam may progress farther and farther up the tubes of the lower set I l with the condensate continually flowing back down the tubes which are maintained at a temperature well above freezing by the incoming steam. When the load materially increases, however, the steam will pass through the entire length of the tubes of the lower set I l without becoming completely condensed therein." The excess of steam may then flow through tank [1 to the tubes I0 of the upper bank and becooled'and condensed therein. The condensate in "these upper tubes will flow downwardly therein concurrently withthe flow of steam therethrough' and, in many instances, in advance of the steam. This condensate is'collected by the partition I5 and is returned tothe tank [2- through the drain pipe l'B. Although the condensate in the tubes of the upper bank may flow ahead of the steam therein, it is to be observed that when these tubes are brought into operation thetubes of the lower set fll are quite warm. Consequently the cold air flowing across the tubes of the lower set is heated thereby and will serve to warm the tubes of the upper set." In this manner the condensate in the tubes of the upper set is kept from freezing even though it flows therethrough in advance of 'the steam.
- In internal combustion engines, particularly those which employ vapor phase cooling or that type of cooling wherein the cooling water is maintained at its boiling point, removal of air and other non-condensable gases from the system is necessary. To this end a vent tube 43 leads into the compartment formed by partition [5 providing an'escapeof such air and non-condensable gases from the system and it will be appreciated thatby placing the vent tube at the outflow end of thesecond set of tubes throughwhlch the vapor passes that theventtube' serves to allow air and non-condensable gases to escape fromthe system without any material-escape of vapor.
In the form. of construction illustratedin Fig. 3, there is a tank 25 which may be supplied with cooling water from the engine at its boiling point. In this tank thereare partitions-26 and 2'! which. define a steam passage 28 leading to the lower end of an mclinedbankof tubes 29. The upper to the water space of the water tank. In this form of construction when a small amount of steam is being delivered to the device this steam .enters the lower ends of the tubes of bank 29 and flows upwardly therein until condensed. Under heavy loads where larger amounts of steam are being developed, that steam which does not condense in the upper bank 29 is caused'to flow downwardly through the tubes of the lower bank 30. In the upper bank condensate flows downwardly through the tubes in a countercurrent direction with respect to the direction of the steam whereas 'in the lower bank 30 condensate flows downwardly through these tubes and may flow in advance of the steam. Where only the tubes of the upper bank are being utilized the counterfiow of condensate through steam pre.-
vents the condensate from freezing even though the cooling air may be extremely cold. When the steam supplied to the condenser increases so that the lower bank 30 is brought into operation, the condensate which flows downwardly through these tubes in advance of the steam is kept from freezing therein due to the fact that the air then passing over these tubes has been adequately heated 'byithe tubes of the upper bank 29. An inlet M'isprovided and leads directly to the tank 25 below the liquid level therein as shown by the dotted lines and an outlet 45 leads'directlyfrom tank 25 and communicates with the tankbelow the liquid level therein. 1 A vent tube 3| is preferably connected through the partition .2! to the outlet space for the lower set of tubes 30. This vent tube serves to conduct off air and other non-condensable gases that maybe introduced into the cooling system. Prefer ably this venttube is arranged in advanceof the tubes of the upper set soas to be cooled bythe air in advance of its being warmed by the tubes of the upper set. Consequently; as this vent tube tubes 35 which may consist of two banks of tubes that are vertically arranged over the'steam space.
that is immediately above the normal water'level indicated by the dotted line 82. The secondset of tubes indicated at 36 is in communication with the upper ends of the tubes of thefirstset through a cover 31. The lower ends of the tubes of the second set drain into a tank 38 from which a pipe 39 leads back to the water space inthe'water jacket. The vent tube for non-condensable .gases is indicated at 40 leading .from: the tank "38 upwardly to a point adjacentthe topof'the. conwith said reservoir, walls defining a third chamberenclosing the lower ends of the lower tubes,
said-third chamber being contained .lwithin thei first chamber and having vapor inlets in the upper-portions thereof whereby vapor from the reservoir may rise andsfiow into thethird chamber through the lower tubes toheatthe outside of the same and then through the upper tubes andinto the second chamber, an airinlet, an air outlet, said sets of tubes beingin an air. passageway which extends from said air inlet to said air outlet with the outside of said upper tubes being in an air stream which inlpassing from said air inletqto said, air outlet flows from the outside of said lower set of tubes to convey heat from the outside of said lower set to the outside of said uppersetm 6.
