<P>PROBLEM TO BE SOLVED: To omit an inverter heat dissipation mechanism of a cooling device or miniaturize it, relating to the cooling device that uses a coolant flow path of a motor and an inverter. <P>SOLUTION: A coolant whose temperature has risen by absorbing heat at an inverter cooling part 2 in upstream is cooled with oil by causing a motor heat exchange part 4 of a coolant flow path to approach the oil for cooling the heat source of a motor 30. As a result, the efficiency of cooling the coolant whose temperature has risen by absorbing heat from the inverter is improved. So, an inverter heat dissipation mechanism 14, in which a coolant releases the heat absorbed from an inverter 20 to the outside, can be omitted or miniaturized. <P>COPYRIGHT: (C)2010,JPO&INPIT |
