A main body (40) for branching refrigerant from a first refrigerant pipe (20) to a plurality of second refrigerant pipes (30) has a first surface (41) to which the first refrigerant pipe (20) is connected and a second surface (42) to which the plurality of second refrigerant pipes (30) is connected. The first plate (50) is joined to the first face (41) and has a first sacrificial anode layer (54) on an outer surface exposed to the atmosphere opposite the body (40). The second plate (60) is joined to the second face (42) and has a second sacrificial anode layer (64) on an outer surface exposed to the atmosphere opposite the body (40).)

1. A refrigerant flow splitter, comprising:

a first refrigerant pipe (20) through which a refrigerant flows;

a plurality of second refrigerant pipes (30) through which the refrigerant flows;

a main body (40) made of aluminum or an aluminum alloy, having a first surface to which the first refrigerant pipe is connected and a second surface to which the second refrigerant pipes are connected, and configured to branch the refrigerant flowing from the first refrigerant pipe to the second refrigerant pipes or to merge the refrigerant flowing from the second refrigerant pipes to the first refrigerant pipe;

a first plate (50) joined to the first face and having a first sacrificial anode layer (54) on an outer surface exposed to the atmosphere opposite the body; and

a second plate (60) joined to the second face and having a second sacrificial anode layer (64) opposite the body at an outer surface exposed to the atmosphere.

2. The refrigerant flow splitter of claim 1,

the first refrigerant pipe and the plurality of second refrigerant pipes have:

a first core material (21) and a second core material (31) which are tubular and made of aluminum or aluminum alloy; and

a third sacrificial anode layer (22, 32) formed on outer peripheral surfaces of the first and second core materials with respect to the first and second core materials.

3. The refrigerant flow splitter as claimed in claim 1 or 2,

the main body includes:

a first cylindrical member (43) made of aluminum or an aluminum alloy; and

a second member (44) having a recess into which the first member is fitted, the second member being made of the same material as the first member,

the first member has the first face on a side opposite to a side fitted into the recess,

the second member has the second face on a side opposite to the recess,

a space for dividing refrigerant is formed in the recess in which the first member is fitted.

4. The refrigerant flow splitter of claim 3,

the first and second members are not formed with a sacrificial anode layer.

5. The refrigerant flow splitter as recited in claim 3 or 4,

the first member and the first plate have a first insertion hole in the first face into which the first refrigerant pipe is inserted,

the second member and the second plate have a plurality of second insertion holes in the second face, into which the plurality of second refrigerant tubes are inserted.

6. The refrigerant flow splitter as recited in any one of claims 1 to 5,

the first and second plates have a fool-proof structure (57, 67), respectively, that blocks the bonding of the first and second sacrificial anode layer sides with the first and second faces.

7. The refrigerant flow splitter as recited in any one of claims 1 to 6,

the first plate has a first plate-like core (53) having a higher electrochemical potential than the first sacrificial anode layer, the first sacrificial anode layer being formed directly on the first plate-like core,

the second plate has a second plate-like core (63) having a higher electrochemical potential than the second sacrificial anode layer, the second sacrificial anode layer being formed directly on the second plate-like core.

8. The refrigerant flow splitter of claim 7,

the main body is made of aluminum alloy,
