Definitions

  • the present invention relates to a technology for an evaporator of an air conditioning system of a vehicle, and more particularly, to a header pipe for connecting a terminal end of a tube through which refrigerant passes.
  • an evaporator of an air conditioning system of a vehicle is formed as a structure in which a core is formed by stacking a plurality of tubes through which refrigerant passes, with fins for dissipating heat and terminal end parts of respective tubes connected by a header pipe,
  • a core 100 is formed by arranging a plurality of tubes 120 between which a heat radiation fin 110 is inserted, a pair of header pipes 200 and 200' disposed on both sides of the core 100, and refrigerant pipes 310 and 320 through which the refrigerant is supplied or discharged connected via an adapter 400 to one header pipe 200' of the pair of the header pipes.
  • the header pipe 200 which is shown in the lower portion of the drawing, includes a tank portion 210 with a refrigerant passageway through which refrigerant flows, a head portion 220 that is formed as a plate with a plurality of through holes 221 and where terminal end portions of the tubes 120 contact are formed, a dividing wall 230 into which a plurality of through holes 231 are formed and that divides the refrigerant passageway space inside the tank portion 210, a dividing plate 240 that is fitted to the dividing wall 230 at a center portion of the tank portion 210 and changes refrigerant passage, and caps 250 and 250' that are respectively coupled to the dividing wall 230 on both ends of the tank portion 210 thereby closing opening portions of the tank portion 210.
  • Such a conventional header pipe 200 including the tank portion 210, the head portion 220, the dividing wall 230, the dividing plate 240, and the caps 250 and 250' is formed by separately assembling each of these components together and then performing brazing in a state that clad material is applied to portions that will be coupled.
  • the conventional header pipe since each component must be assembled together before the brazing, the conventional header pipe has problems of productivity decrease and cost increase due to an increase of the total number of components.
  • incompletely coupled portions among the brazed portions may exist at portions at which clad material is not applied, and the refrigerant may leak from the incompletely coupled portions, thereby deteriorating performance of the evaporator.
  • the present invention has been made in an effort to solve the above problems, and it is an object of the present invention to provide a header pipe of an evaporator for a vehicle in which the number of components to be assembled can be decreased and refrigerant leakage may be minimized or prevented at attached portions after brazing each component.
  • a tank portion provided with a refrigerant passageway space and a head portion to which a terminal end portion of a refrigerant tube contacts are integrally formed, and a dividing wall partitioning the refrigerant passageway space of the tank portion, a dividing plate for changing a refrigerant passageway in the tank portion, and a cap for closing opening portions disposed at both ends of the tank portion are assembled.
  • a rounded portion may be formed at a portion in which the tank portion and the head portion contact each other.
  • Each of the dividing wall, the dividing plate, and the cap may be coupled to an integrated member of the tank portion and the head portion through brazing using a paste.
  • a rail groove into which the dividing wall is slidably inserted may be provided to each of the tank portion and the head portion, and an insertion hole into which the dividing plate is fitted may be formed in the tank portion.
  • FIG. 1 is a perspective view of a conventional evaporator
  • FIG, 2 is an exploded perspective view of a header pipe according to an embodiment of the present invention
  • FIG. 3 is an enlarged perspective view of a right end portion in FIG. 2.
  • FIG, 4 is a perspective view showing a state during insertion of a dividing wall in the header pipe according to an embodiment of the present invention.
  • FIG. 5 is a perspective view showing an assembled state of a header pipe according to an embodiment of the present invention
  • FIG. 6 is an enlarged perspective view of a right end portion in FIG. 5.
  • FIGs. 2, 4, and 5 are respectively an exploded perspective view, a perspective view showing a state during assembly, and a perspective view showing an assembled state of a header pipe according to an embodiment of the present invention
  • FIGs. 3 and 6 are respectively an enlarged perspective view of a right end portion in FIG. 2 and an enlarged perspective view of a right end portion in FIG.
  • a header pipe forms a hollow tube shape by a tank portion 10 having a refrigerant passageway space through which refrigerant flows, and a head portion 20 that is provided with a plurality of through holes 21 for contacting a terminal end portion of a refrigerant tube (not shown) and covers the refrigerant passageway space of the tank portion 10, and the tank portion 10 and the head portion 20 are integrally formed through a method such as extrusion forming.
  • a rounded portion R is formed at a portion in which the tank portion 10 and the head portion 20 contact each other, so that flow of refrigerant flowing through the header pipe may become performed more smoothly.
  • a dividing wall 30 partitioning the refrigerant passageway space of the tank portion 10 is assembled within the tank portion 10
  • a dividing plate 40 for changing a refrigerant passageway is assembled near a center portion of the tank portion 10
  • caps 50 and 50' for closing opening portions disposed at both ends of the tank portion 10 are assembled to both ends of the tank portion 10.
  • the dividing wall 30, the dividing plate 40, and the caps 50 and 50' that are respectively assembled to an integrated member of the tank portion 10 and the head portion 20 may be coupled through brazing using a paste that is liquefied by adding a binder into a clad material.
  • the dividing plate 40 is assembled to the dividing wall 30, and the caps 50 and 50' are assembled to both opening portions of the tank portion 10, the dividing wall 30, and the dividing plate 40, and the caps 50 and 50' may be coupled to the integrated member of the tank portion 10 and the head portion 20 through brazing using a clad material. As shown in FIGs.
  • rail grooves 11 and 22 into which the dividing wall 30 is slidably inserted are respectively provided to the tank portion 10 and the head portion 20, these rail grooves 11 and 22 are formed in a shape of a rail such that an insertion end of the dividing wall 30 may slidably inserted thereinto, and the rail grooves 11 and 22 and the dividing wall 30 are firmly attached to each other since the paste or the clad material is fused at a contacting portion of the rail grooves 11 and 22 and the dividing wall 30 and around the contacting portion during the brazing.
  • an insertion hole 12 into which the dividing plate 40 is fitted is formed in the tank portion 10, and the dividing plate 40 that is fitted into the insertion hole 12 is firmly coupled by fusion of the paste or the clad material during the brazing.
  • the tank portion 10 and the head portion 20 are integrally formed, a total number of components to be assembled is decreased when compared to the conventional header pipe, and furthermore, since the number of portions that are coupled by the brazing are decreased when compared to the conventional header pipe, leaks of refrigerant at the coupled portions after the brazing can be minimized or prevented.
  • a number of components to be assembled is decreased, so that productivity is improved and manufacturing cost is decreased, and in addition, performance of the evaporator may be improved since leaks of refrigerant after the brazing can be minimized or prevented.
