Abstract
An electrical wiring material having a cooling function is characterized by a long hollow conductive body within which operating fluid is internally confined. An electrical connection piece is provided at the end portions of the conductive body, or other portions thereof. When used to wire electronic apparatuses, resulting heat is radiated due to evaporation and condensation of the operating fluid within the hollow conductive body. The wiring material may be used to wind a transformer, particularly the low voltage side, to provide a self cooling transformer.
Claims14
An electrical wiring material, comprising:
- a hollow conductive body having an elongated length;
- an operating fluid confined within said hollow conductive body;
- said hollow conductive body being deformed at at least one location along said length therewith to define in said hollow conductive body a flattened electrical connection piece at said at least one location;
- and
- a remainder of said hollow conductive body including at least one hollow segment, said at least one hollow segment being bounded on at least one side by said electrical connection piece.
A transformer, comprising:
- a hollow conductive body having an elongated length;
- an operating fluid confined within said hollow conductive body;
- said transformer including a low voltage side wound with said hollow conductive body.
