Abstract (en)
[origin: EP3828490A1] When a joint is used to connect a multi-hole flat pipe and a cylindrical pipe, a problem may occur in that oil accumulates in the vicinity of a connection portion. This problem may be significant in a refrigeration apparatus that uses a carbon dioxide refrigerant, for which oil has high importance. A joint (34) includes a first connection portion (301) that covers an outer side of an end portion of a multi-hole flat pipe (300), and a body (302) that is continuous from the first connection portion (301). An inside dimension (L<sub>302</sub>) of the body (302) in a vertical direction is larger than an inside dimension (L<sub>301</sub>) of the first connection portion (301) in the vertical direction. Here, the vertical direction is a thickness direction of the multi-hole flat pipe (300) (thickness T, width W, W > T).
