Definitions

  • This invention relates to the use of apparatus for increasing the supply of compressed air to an engine such as a turbocharger, super ⁇ charger and the like. It is desirable to cool such compressed air being introduced into an engine in order to obtain efficient combustion. Unless the air is cooled the engine may tend to become over- heated. The use of a coolant is not desirable because it utilizes power from the engine.
  • United States Patent No. 4,033,406 discloses the use of a heat exchanger for use in a cooling tower by the use of heat pipes extending across inlet and outlet housings.
  • cross over or compressed air may be cooled to a predetermined temperature, and increased moisture which results from such cooling, collects and is removed before the introduction of the cross over air to an engine such as a gasoline engine, a diesel engine or an external combustion engine and the like.
  • the cross over air is passed over heat tubes which extend across the path of the cross over air.
  • the heat tubes extend out of the path of the cross over air and thence into the path of ambient air flow.
  • the amount of ambient air flow ⁇ ing across the heat tubes may be controlled by a sensor carried in the cross over air flow preferably after cooling.
  • the moisture which results from the temperature drop may be collected in a coalesser section which utilizes an abrupt change of direction as well as collecting surfaces for collecting and the expelling of moisture.
  • Figure 1 is a perspective view illustrating an engine having a turbocharger equipped with apparatus for treating cross over air constructed in accordance with the present invention.
  • Figure 3 is a transverse sectional elevation taken on the line 3-3 in Figure 1.
  • the drawings illustrate an apparatus for cooling and removing moisture from compressed air passing from a turbocharger and the like to an intake of a combustion engine.
  • An air duct A connects the turbo ⁇ charger to the intake of the internal combustion engine.
  • a plurality of heat pipes B extend across the air duct for receiving heat from the compressed air passing through the air duct.
  • a portion of the heat pipes extend from the air duct into a zone C of ambient air external to the air duct for transferring heat received from the compressed air to the ambient air thus cooling the compressed air.
  • a coalesser zone D receives the compressed air after cooling for removing moisture therefrom.
  • Means E including a damper controls air flow in the zone of ambient air over the portion of the heat pipes for controlling the cooling of the compressed air.
  • the heat exchanger apparatus hereof utilizes closed heat tubes containing freon to transfer heat from the compressed intake air stream to the ambient air remote from the intake air stream.
  • the finned heat tubes are illustrated as being arranged to give maximum cooling and minimum restriction of air flow.
  • Air is illustrated as passing from a turbo- charger 10 which receives exhaust air as from a diesel engine 11.
  • the engine is illustrated as including a block 11a, a cylinder head lib and a valve cover lie.
  • the turbocharger 10 receives exhaust air from an exhaust manifold 12 carried by the cylinder heat lib.
  • a cross over includes the usual duct 13 communicating on one end with the turbo ⁇ charger 10 and with an enlarged air duct portion 14 on the other end.
  • the air duct A includes the usual duct 13 and the enlarged air duct portion 14.
  • a plurality of heat pipes B are illustrated as including the usual tube 15 and spaced transverse heat transfer fins 16 carried thereon. The heat pipes B extend across the enlarged air duct portion 14 as well as a zone C of ambient air.
  • the zone C includes an air duct 17.
  • a coalesser zone D includes a passageway 18 formed by a lower portion of the enlarged air duct portion 14.
  • Wire mesh packing 19 is carried in the coalesser zone D and collects the water droplets formed by the lowering of the temperatures of the exhaust air passing over the heat pipes A.
  • Means E includes a damper 20 and a sensing and control means therefor in the form of a bimetallic strip 21 ( Figure 1).
  • the damper is illustrated as being pivotally mounted on a pin as at 21a in an inlet passageway 22 in the air duct 17.
  • the damper is controlled by the sensing action of the bimetallic strip which is mounted in the air duct portion 14 and has connection with the pin 21a.
  • An outlet passage- way 23 is provided.
  • a drain 24 is provided for determining the moisture collected in the lower portion of the coalesser section.
  • heated compressed air passes from the turbocharger and the like across the heat tubes contained in the plenum portion 14 of the duct to a lower coalesser section from whence the conditioned air is passed into the engine.
  • Heat is transferred efficiently and quickly from the heated air to a controlled flow or ambient air passing over a portion of said heat tubes extending externally of the flow path of the heated air in the plenum portion 17 of the ambient zone.
  • a relatively large moisture collecting surface is provided by the wire mesh, and the change of direction of air in the duct resulting from the abrupt change of direction or angle of the duct leading to the engine facilitates collecting of the moisture. Excess moisture is eliminated through the drain 24.
  • the damper 20 is controlled through the operation of the bimetallic strip. While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following -claims.
  • Apparatus for cooling and removing moisture from compressed air passing from a turbocharger and the like to an intake of an engine comprising: an air duct connecting the turbocharger to the intake of the engine; a plurality of heat pipes extending across said air duct for receiving heat from said compressed air passing through said air duct; a portion of said heat pipes extending from said air duct into a zone of ambient air external to said air duct for transferring heat received from said compressed air to said ambient air thus cooling n said compressed air; and a coalesser zone receiving said compressed air after cooling for removing moisture therefrom.
