STRUCTURE FOR CONNECTING REFRIGERANT PIPE

摘要

PURPOSE: A refrigerant pipe connecting structure is provided to guarantee the air-tightness of a refrigerant pipe connection part and to prevent damage to a welded part when the refrigerant pipe vibrates. CONSTITUTION: A refrigerant pipe connecting structure comprises a flare nut(50) and a socket(40). One side of a flare nut is inserted into a first refrigerant pipe(31) and moves along the longitudinal direction of the outer circumference of the first refrigerant pipe. A female screw is formed on the inner circumference of the flare nut. One side of the socket is formed on the inner circumference of an expanded part(31a) of the first refrigerant pipe. The socket is installed in a second refrigerant pipe(32) and moves along the longitudinal direction of the outer circumference of the second refrigerant pipe.
