Definitions

  • This invention relates to the field of mechanics, especially to a heat exchange machinery, more especially to a heat exchanger, particularly a parallel evaporator, which is used in an air conditioner of an automobile.
  • a heat exchanger used in an air conditioner of an automobile is consisted of a plurality of evaporators connected in series. This results in that the air conditioner is bulky and heavy, which increases the load of the automobile. Furthermore, the efficiency of the heat exchange is low and it is hard to save energy.
  • An object of the present invention is to provide a parallel flow evaporator, which can overcome the deficiencies of the prior art automobile air conditioner that the efficiency of heat exchange is low and it is hard to save energy.
  • the parallel flow evaporator of the present invention comprises a transitional plate, wherein a left side plate is secured vertically to a left side edge of said transitional plate, a right side plate is secured vertically to a right side edge of said transitional plate, a first liquid inlet manifold is secured to an upper side edge of a forward side surface of said transitional plate, a first gas outlet manifold is secured to an upper side edge of a rearward side surface of said transitional plate, a second liquid inlet manifold is secured to a lower side edge of the forward side surface of said transitional plate, and a second gas outlet manifold is secured to a lower side edge of the rearward side surface of said transitional plate; said first liquid inlet manifold, said first gas outlet manifold, said second liquid inlet manifold and said second gas outlet manifold are parallel with each other; a plurality of flat tubes, which are parallel with and distant from each other, are arranged between said first liquid inlet manifold and said second liquid inlet manifold;
  • both of said coolant inlet and said coolant outlet are provided on a pressing plate, and said pressing plate is connected with the left side plate.
  • each of the first liquid inlet manifold, the first gas outlet manifold, the second liquid inlet manifold and the second gas outlet manifold is U-shaped in cross-section.
  • the principle of the present invention is as follows: liquid coolant enters the second liquid inlet manifold through the coolant inlet, then flows through the flat tubes to effect heat exchange, and thus turns into gas coolant; after flowing through the first liquid inlet manifold and the first gas outlet manifold, the gas coolant enters the second gas outlet manifold and is discharged through the coolant outlet.
  • the flat tubes facilitate efficient heat exchange of the coolant with the environment, and the fins between the flat tubes increase the area of heat transfer, so that the heat exchange efficiency is improved. With the cross sections of the liquid inlet manifolds and the gas outlet manifolds being U-shaped, the flow resistance is reduced.
  • the effects of the present invention are positive and obvious.
  • flat tubes and fins are provided in the parallel flow evaporator, and the liquid inlet manifolds and the gas outlet manifolds are designed as U-tubes, so the heat exchange efficiency of the parallel flow evaporator is improved.
  • FIG. 1 is a front schematic view of a parallel flow evaporator of the present invention
  • FIG. 2 is a bottom schematic view of a parallel flow evaporator of the present invention
  • FIG. 3 is a left schematic view of a parallel flow evaporator of the present invention.
  • the parallel flow evaporator of the present invention comprises a transitional plate 12 , wherein a left side plate 5 is secured vertically to a left side edge of said transitional plate 12 , a right side plate 6 is secured vertically to a right side edge of said transitional plate 12 , a first liquid inlet manifold 13 is secured to an upper side edge of a forward side surface of said transitional plate 12 , a first gas outlet manifold 14 is secured to an upper side edge of a rearward side surface of said transitional plate 12 , a second liquid inlet manifold 3 is secured to a lower side edge of the forward side surface of said transitional plate 12 , and a second gas outlet manifold 4 is secured to a lower side edge of the rearward side surface of said transitional plate 12 ; said first liquid inlet manifold 13 , said first gas outlet manifold 14 , said second liquid inlet manifold 3 and said second gas outlet manifold 4 are parallel with each other;
  • both of said coolant inlet 1 and said coolant outlet 2 are provided on a pressing plate 11 , and said pressing plate 11 is connected with the left side plate 5 .
  • a connecting plate 10 is provided between the pressing plate 11 and the left side plate 5 .
  • each of the first liquid inlet manifold 13 , the first gas outlet manifold 14 , the second liquid inlet manifold 3 and the second gas outlet manifold 4 is U-shaped in cross-section.
