  • Refrigerant distributor and air conditioner
    Patent number: 11137184
    Abstract: A refrigerant distributor includes a first refrigerant pipe, a plurality of second refrigerant pipes, a body, a first plate, and a second plate. The body is made of aluminum or aluminum alloy. The body is configured to distribute a refrigerant from the first refrigerant pipe into the second refrigerant pipes or merge the refrigerant flowing from each of the second refrigerant pipes into the first refrigerant pipe. The body has a first surface connected to the first refrigerant pipe and a second surface connected to the second refrigerant pipes. The first plate is joined to the first surface, and has an outer surface exposed to atmosphere and provided with a first sacrificial anode layer for the body. The second plate is joined to the second surface, and has an outer surface exposed to atmosphere and provided with a second sacrificial anode layer for the body.
