    DETAILED DESCRIPTION
  • An exemplary embodiment of the present invention will hereinafter be described in detail with reference to the accompanying drawings.
  • FIG. 1 shows an apparatus for cooling exhaust gas according to an exemplary embodiment of the present invention, FIG. 2 shows a first cooling portion and a second cooling portion of an apparatus for cooling exhaust gas according to an exemplary embodiment of the present invention, and FIG. 3 shows a view that a first cooling portion and a second cooling portion are separated according to an exemplary embodiment of the present invention.
  • As shown in FIG. 1 and FIG. 2, an apparatus for cooling exhaust gas includes an exhaust gas passage 209, at least one first cooling portion 101, and at least one second cooling portion 103.
  • The exhaust gas flows in the exhaust gas passage 209.
  • The first cooling portion 101 includes a coolant inlet 107 and an exhaust gas inlet 105 and cools the exhaust gas.
  • The second cooling portion 103 includes a coolant outlet 111 and an exhaust gas outlet 109 and cools the exhaust gas cooled from the first cooling portion 101.
  • That is, the exhaust gas inflows through the exhaust gas inlet 105 and is exhausted through the exhaust gas outlet 109. (referring to solid line arrow).
  • In addition, coolant inflows through the coolant inlet 107 and is exhausted through the coolant outlet 111.
  • Preferably, the first cooling portion 101 and the second cooling portion 103 can be made of different material.
  • That is, the coolant and the exhaust gas inflow through the first cooling portion 101 and are then supplied to the second cooling portion 103.
  • Suitably, the heat conductivity of the first cooling portion 101 and the heat conductivity of the second cooling portion 103 may be different.
  • More suitably, according to an exemplary embodiment of the present invention, the heat conductivity of the first cooling portion 101 may be lower than that of the second cooling portion 103.
  • That is, the exhaust gas of higher temperature is cooled in the first cooling portion 101. The exhaust gas cooled in the first cooling portion 101 is then cooled in the second cooling portion 103.
  • Referring to FIG. 2, the first cooling portion 101 includes a plurality of first plates 201, a plurality of second plates 203, and a fin 205.
  • The first plates 201 contact the coolant, the second plates 203 are disposed in the first plates 201, and the exhaust gas flows the second plates.
  • The fin 205 is disposed to absorb the heat of the exhaust gas of the second plate 203 and made of steel material.
  • As shown in FIG. 1 and FIG. 3, the apparatus for cooling the exhaust gas includes a plurality of first cooling portions 101 and a plurality of second cooling portions 103.
  • Because the coolant flows between a plurality of the first cooling portions 101 and the exhaust gas flows in the first cooling portion 101, heat exchange between the exhaust gas and the coolant is realized.
  • In particular, referring to FIG. 2, the coolant flows outside the first plates 201 and the exhaust gas flows between the second plates 203.
  • Heat exchange between exhaust gas and coolant is realized by the fin 205 of the first cooling portion and the fin 207 of the second cooling portion.
  • Although the first cooling portion 101 and the second cooling portion 103 have the same shape, they have fins of different material.
  • Particularly, the fin 205 of the first cooling portion 101 may be made of the steel material and the fin 207 of the second cooling portion 103 may be made of an aluminum material.
  • The hot exhaust gas is cooled by in the first cooling portion 101 including the steel material fin 205 having an excellent heat resistant performance to a temperature that can be applied to the fin of aluminum material.
  • The exhaust gas is then re-cooled in the second cooling portion 103 including the fin 207 made of the aluminum material.
  • As shown in FIG. 3, because the first cooling portion 101 and the second cooling portion 103 are made of different materials, it is impossible that the first cooling portion 101 and the second cooling portion 103 are connected by a method such as welding or brazing.
  • Rather, the first cooling portion 101 and the second cooling portion 103 can be coupled, for example, by bolt (not shown).
  • Preferably, for preventing a leakage of the exhaust gas or the coolant, a gasket 301 may be disposed between the first cooling portion 101 and the second cooling portion 103.
  • The heat conductivity of aluminum material is higher than that of stainless steel material. Aluminum material is less expensive than stainless steel material. Also, aluminum material is lighter than stainless steel material. As a result, the present invention can overcome the problems of conventional systems by reducing manufacturing costs and the apparatus volume and weight.
  • While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
