Patent CA-2636182-A1 (CA)
Inventor: ERDMAN WILLIAM
IPC: H05K7/20
Filed: 2007-02-22
Abstract: A method for conducting heat generated in electronic equipment housed within a wind power tower (1) by using the tower as a heat sink for cooling purposes.  The transfer of heat occurs by liquid cooling of the electronic equipment and by circulating the liquid through a heat exchanger, which is thermally attached to the tower. The wind blowing over the tower at high wind speeds and power levels then cools the tower. One method uses a copper tube (13), which is in thermal contact with the tower. A second method mounts heat-generating components directly to the tower. A third method uses a liquid- to-air heat exchanger placed at intervals over the outside circumference of the tower. In all three cases the tower standing in the wind is used to remove heat from the control system.
