Title: Innovations by Yu Ofune

Introduction

Yu Ofune is a notable inventor based in Kariya, Japan, recognized for his contributions to vehicle temperature control systems. He holds a total of 10 patents, showcasing his expertise in automotive technology and innovation.

Latest Patents

Among his latest inventions is an in-vehicle temperature control system. This system features a low-temperature circuit with a chiller, where cooling water circulates. It includes a heat dissipation unit that dissipates heat to the air and a refrigeration circuit that absorbs heat from the cooling water to the refrigerant at the chiller. The system also has a ratio adjusting device for managing the heat dissipation unit's passing ratio and a controller that adjusts the heat transfer amount in the refrigeration circuit. If the temperature of the cooling water is predicted to decrease, the controller increases the heat transfer amount and decreases the ratio before the cooling water's temperature actually drops.

Another significant invention is a cooling apparatus for a vehicle driving system. This apparatus activates a heat pump to cool a hybrid system using a cooling medium. It circulates engine cooling water through a condenser to cool the cooling medium when specific engine water circulation conditions are met. The system is designed to optimize the cooling processes for both the hybrid system and the internal combustion engine.
