The turbine converts the fluid energy of the working fluid into the kinetic energy of the turbine, and the converted kinetic energy of the turbine is converted into electrical energy by the generator. The heat generated during this process may damage the turbine assembly or cause the turbine to malfunction. To prevent this, the refrigerant within the turbine housing can be circulated.

During the turbine operation process, the circulating refrigerant exchanges heat with the turbine assembly or working fluid by convection or radiation. During this process, the temperature of the refrigerant increases, and to prevent this, an efficient circulation system for the refrigerant is required.

For this purpose, various attempts have been made to form a flow path in the conventional turbine to smoothly recover the refrigerant. However, there was a problem that the working fluid and refrigerant remaining in the narrow hollow within the housing could not be efficiently recovered simply by forming a flow path connected to the housing.

As described above, there is a need to develop a turbine assembly that can solve the problems of the prior art.
