Document Type and Number:
Japanese Patent JP2023099241
Kind Code:
A
Abstract:
To provide a heat transfer pipe which facilitates molding during manufacturing while improving heat exchange efficiency.SOLUTION: In a heat transfer pipe 8 according to the disclosure, a pair of plate-like heat transfer pipe components 12 having the same shape are joined to form refrigerant passages 9. The heat transfer pipe component 12 has: a first area 14 in which multiple protruding parts 13 protruding from a surface 12a and extending along the surface 12a are arranged spaced apart from each other; and a second area 15 which is located adjacent to one side as seen in an arrangement direction of the protruding parts 13 of the first area 14 and provided with no protruding part 13. The pair of heat transfer pipe components 12 are joined with apical surfaces 13a as seen in a protruding direction of the protruding parts 13 facing each other and the refrigerant passages 9 are formed along an extending direction of the protruding parts 13 between the adjacent protruding parts 13. One second area 15 and the other second area 15 are arranged so as to be located at the sides opposite to the respective first areas 14.SELECTED DRAWING: Figure 6
