1. A turbine casing, comprising:
- a casing body;
a first heat pipe disposed in the casing body and comprising a first working medium having a first boiling point, the first heat pipe including a first vaporization section and a first condensation section, wherein the first vaporization section is located forward the first condensation section; and
a second heat pipe disposed in the casing body and comprising a second working medium having a second boiling point different from the first boiling point of the first working medium, wherein the second heat pipe is circumferentially adjacent to the first heat pipe.

Abstract
A turbine casing may comprise a casing body and a first heat pipe disposed in the casing body. The first heat pipe may comprise a first working medium. The first heat pipe may include a first vaporization section and a first condensation section. The first vaporization section may be located forward the first condensation section. A second heat pipe may be disposed in the casing body and may comprise a second working medium different from the first working medium.
