Info

Prius' inverter is totally amazing." Even if the battery fails, Prius can run on the gasoline engine and the generator. However, if the computer and the inverter fail, the car will immediately stop in the middle of the street. To prevent serious accidents, these two items were designed and developed with great care. Uchiyamada was amazed by the story about the trains, and said, "If I had known about that story earlier, I would not have had the guts to develop it ourselves." 247
Chapter 9 Cooling the THS - Radiator Under the hood of a car, there is a radiator up front to cool the engine, and next to it is a condenser of a similar shape for cooling the air conditioning coolant. These two off-stage helpers function, prevent the car from overheating and help the air conditioning system. Prius has one more item needing cooling. It is the special radiator to cool electric components, such as the motor and the inverter. At Electronics Engineering Division IV, which provided the IGBT, engineers decided to solve the heat problem with an exterior-cooling device because they were unable to find any other way. An expert in cooling Staff Leader Shunkichi Suzaki who handled the cooling system had worked in the same testing department as Chief Engineer Uchiyamada. After joining the company in 1968, he worked on engine cooling for 23 years until 1991, becoming an expert test engineer in the field. After moving to Electric Vehicle Division in July 1993, he was in charge of cooling energy and heat collection for RAV4EV. He then moved to Vehicle Development 248
