Claims

[Scope of utility model registration request]

In a structure in which piping is connected to a heat exchanger including a flat tube formed in a flat shape and a header pipe attached to an end of the flat tube, a through-hole is interposed between the piping and the header pipe and has a through hole inside. The connection part includes a block having a notch on one side that fits into the side surface of the header pipe, and a piping connection part protruding from the other side of the block, The through hole extends from the protruding end of the piping connection part to the block, and forms a hole in the side surface of the header pipe, the notch communicates with the side surface of the header pipe, and the through hole of the connecting part communicates with the hole. A pipe connection structure for a heat exchanger, characterized in that the blocks are fitted together as shown in FIG.
