Abstract
This invention concerns a transformer radiator. The radiator includes an inlet manifold, an outlet manifold and a heat exchange fin. The find extends between and is connected to the inlet and outlet manifolds. The heat exchange fin defines at least one oil flow passage to convey transformer oil, which, in use, enters the radiator through the inlet manifold, to the outlet manifold. The heat exchange fin is further provided by a single component having a continuously undulating profile and the manifolds extend transversely to the turns of the undulating profile.
Claims10
A transformer radiator including:
- an inlet manifold;
- an outlet manifold;
- and
- a heat exchange fin extending between and connected to the inlet and outlet manifolds, wherein the heat exchange fin defines at least one oil flow passage to convey transformer oil, which, in use, enters the radiator through the inlet manifold, to the outlet manifold, and wherein the heat exchange fin is provided by a single component having a continuously undulating profile formed by alternating bends and straight, parallel turns between the bends, and wherein the manifolds extend transversely to the turns of the undulating profile;
- wherein the single component of the heat exchange fin comprises a pair of metal sheet portions sealed to one another peripherally and separated from one another at least at one location inside the periphery so as to form the at least one oil flow passage.
A method of manufacturing a transformer radiator including:
- locating two portions of metal sheeting adjacent one another;
- sealing the two portions of metal sheeting peripherally to one another;
- deforming the metal sheeting to form a heat exchange fin with a continuously undulating profile formed by alternating bends and straight, parallel turns between the bends;
- providing internal pressurization between the two portions of metal sheeting to force them apart from one another at least at one location inside the periphery of the joint sheeting thereby to form the at least one oil flow passage;
- providing each turn of the heat exchange fin carrying an oil flow passage with an inlet opening and an outlet opening;
- providing an inlet manifold and an outlet manifold;
- connecting the inlet openings in a sealed manner to openings in the inlet manifold and connecting the outlet openings in a sealed manner to openings in the outlet manifold.
