Abstract
An electrical apparatus, such as a distribution transformer, provided with heat pipes for cooling. The apparatus is provided with attachment wells, either extending into the cooling fluid of the apparatus or secured along the outside wall of the apparatus. Heat pipes are provided which fit into the attachment wells, with the evaporator section of the heat pipe mounted in the wells. The condenser section of the heat pipe extends away from the apparatus. Thermally conductive grease is placed in the wells to minimize the temperature drop from the wells to the evaporator section of the heat pipe.
