Refrigerant distributor and air conditioner

A refrigerant distributor comprising:

• a first refrigerant pipe allowing a refrigerant to flow therethrough:
• a plurality of second refrigerant pipes allowing the refrigerant to flow therethrough;
• a body made of aluminum or an aluminum alloy, the body having a first surface connected to the first refrigerant pipe and a second surface connected to the plurality of second refrigerant pipes, and the body being configured to distribute the refrigerant flowing from the first refrigerant pipe into the plurality of second refrigerant pipes or merge the refrigerant flowing from each of the second refrigerant pipes into the first refrigerant pipe;
• the body including
• a first member made of aluminum or an aluminum alloy and having a cylindrical shape, and
• a second member having a concave portion receiving the first member and made of a material of the first member,
• the first member having the first surface on a side opposite to a side fitted into the concave portion,
• the second member having the second surface on a side opposite to the concave portion, and
• the concave portion receiving the first member having an internal space for distribution of the refrigerant;
• a first plate joined to the first surface, the first plate having an outer surface that is exposed to atmosphere, and the outer surface of the first plate being provided with a first sacrificial anode layer for the body;
• and
• a second plate joined to the second surface, the second plate having an outer surface that is exposed to atmosphere, and the outer surface of the second plate being provided with a second sacrificial anode layer for the body,
• the first sacrificial anode layer not contacting the first member, and the second sacrificial layer not contacting the second member,
• the first member and the first plate having a first fitting hole provided in the first surface and receiving the first refrigerant pipe, and
• the second member and the second plate having a plurality of second fitting holes provided in the second surface and receiving the plurality of second refrigerant pipes.
