Abstract
Official abstract text for this publication.
Power supply equipment at least partially provided under a ground surface and capable of supplying power to a vehicle comprises a connector connectable to the vehicle in order to supply power to the vehicle on the ground surface, a power supply circuit (a power conversion circuit) that supplies power to the connector, and a cooler (a fin) that cools the power supply circuit using a substance existing under the ground surface. Thus, the power supply circuit that supplies power for feeding power to the vehicle is cooled by using the substance existing under the ground surface. The substance existing under the ground surface is normally lower in temperature than a heat generating portion of the power supply circuit. Therefore, the substance having a low temperature is used to cool the heat generating portion of the power supply circuit. The power supply equipment can thus efficiently exhaust heat.
First claim
Opening claim text (preview).
What is claimed is: 1 . Power supply equipment at least partially provided under a ground surface and capable of supplying power to a vehicle, comprising: a connector cable that is connectable to the vehicle to feed power to the vehicle on the ground surface; a power converter that supplies power to the connector cable; and a cooler that cools the power converter using a substance existing under the ground surface. 2 . The power supply equipment according to claim 1 , wherein the cooler includes a fin capable of heat transfer from the power converter, and the fin is disposed in contact with the substance. 3 . The power supply equipment according to claim 1 , wherein the substance is a fluid, and the cooler includes a passage unit that passes the substance to the power converter. 4 . The power supply equipment according to claim 3 , wherein the passage unit draws the substance from a source under the ground surface and returns the substance to the source after the substance is passed through the power converter. 5 . The power supply equipment according to claim 3 , wherein the passage unit discharges the substance on the ground surface after the substance is passed through the power converter.
