摘要： An outdoor heat exchanger (13) includes a liquid side header (52) and a heat transfer tube (53). The liquid side header (52) guides a refrigerant. The heat transfer tube (53) is connected to the liquid side header (52) and causes heat exchange between the refrigerant and a medium. The liquid side header (52) includes an inner board (62), an inner board (63), and an outer board (61). The inner board (62) has a surface (622). The inner board (63) has a surface (631) facing the surface (622). The outer board (61) has a surface (614). The surface (614) crosses the surface (622) and the surface (631), and is bonded to the inner board (62) and the inner board (63). The surface (622) and the surface (631) are bonded by a brazing material having a first thickness. The surface (614) and the inner board (62) are bonded by a brazing material having a second thickness. The surface (614) and the inner board (63) are bonded by a brazing material having a third thickness. The first thickness is less than the second thickness. The first thickness is less than the third thickness. The first thickness is 0.2 mm or less.

摘要： A heat exchanger, of the type including side shoulders (3), between which the pack of fins (1) and the heat exchange pipes (4) are accommodated, wherein a section (5) of the pipes (4) is arranged protruding outside of at least one of said shoulders (3). Joints (6) are also provided for the connection between the aforementioned pipe sections (5) at respective widened portions (11) of the latter. According to the invention, the pipe sections (5) are provided with a protective and reinforcing sleeve (12).
The sleeve (12) allows the pressure resistance capability of the exchanger pipe to be fully exploited, thanks also to the contribution provided by the set of fins.-

摘要： A refrigerator includes a cabinet (10) that defines a storage space and a machine compartment (11) that accommodates a compressor, a blow fan, and a condenser (50). The condenser (50) is curved along front, rear, and side surfaces of the machine compartment. The condenser includes a first header (53) disposed at a first end of the condenser, a second header (55) disposed at a second end of the condenser, tubes that connect the first header and the second header to each other, heat exchange fins disposed the tubes, an input connection portion (531) that extends from the first header toward the second header and is configured to supply refrigerant to the first header, and an output connection portion (532) that extends from the first header toward the second header and is spaced apart from the input connection portion. The output connection portion is configured to receive the refrigerant discharged from the first header.
A refrigerator comprising:
a cabinet (10) that defines a storage space and a machine compartment (11) therein, the machine compartment being separated from the storage space;
a condenser (50) disposed in the machine compartment, the condenser (50) being curved, the condenser (50) comprising:
a first header (53) disposed at a first end of the condenser (50),
a second header (55) disposed at a second end of the condenser (50),
an input connection portion (531) connected to the first header (53), and
an output connection portion (532) connected to the first header (53) and being spaced apart from the input connection portion (531).-

摘要： A heat exchanger includes housing, a core, a pair of collector plates and a pair of tanks. The housing receives first heat exchange fluid. The core includes tubes and fins, wherein the tubes are received inside housing with the fins lodged between adjacent tubes. The pair of collector plates is disposed at end portions of the tubes. The collector plates are configured with slots that receive the respective end portions of tubes. The pair of tanks is connected to respective collector plates. The end portions of each tube include tabs configured thereon. The tabs configured on at least one pair of opposite sides of section at respective end portions of tube fuse to form a part of welding joint between end portions of tube and corresponding slots.
