The connector body 1 has a medium channel 11 and a cavity 12 inside. One end of the auxiliary connectors 2 communicates with the cavity 12, and the medium channel 11 is located within the cavity 12. Both sides of the connector body 1 are connected to cooling pipes, and the auxiliary connectors 2 are connected to the cooling pipes on both sides. The medium passage formed by the auxiliary connectors 2 and the cavity 12 does not interfere with the medium channel 11, achieving dual-channel conductivity.

[0018] The auxiliary connector 2 includes a connecting flange 21 and a bend 22. The connecting flange 21 is embedded in the connector body 1 and has internal threads. One end of the bend 22 has an external hexagonal nut and external threads, and the other end of the bend 22 has a connector 23. The bend 22 is threadedly connected to a hexagonal nut. The outer wall of the connector 23 has external threads, and the end of the connector 23 has a first sealing groove 24, in which a sealing ring is installed.
