In a vehicle transformer including a core (1), a winding (2), a rectangular tank (3) holding them, a cooling unit (7) for cooling a cooling medium (6) filling the tank (3), and a circulating pump (8) for forcibly circulating the cooling medium (6), a partition member (9) is provided for dividing an interior of the tank (3) into two and the partition member (9) divides a channel of the cooling medium (6) flowing within the winding (2) into a first cooling medium channel (10) and a second cooling medium channel (11), and both of the cooling medium channels (10, 11) are communicating at one end side of the tank (3) and the cooling unit (7) connected to both of the cooling medium channels (10, 11) is provided at the other end for the cooling medium (6) to flow and circulate in the first cooling medium channel (10) and the second cooling medium channel (11). Thereby, the connection between the tank and the cooling unit is simplified and a vehicle transformer reduced in size and weight is obtained. |
