Latest Patents

Nakajima's latest patents include an exhaust heat recovery device and an exhaust heat recovery apparatus. The exhaust heat recovery device features a first flow path member and a second flow path member that includes a heat exchange unit. This unit is designed to perform heat exchange between exhaust gas and a refrigerant. The device also incorporates a valve mechanism that switches between opening and closing the flow paths, along with a drive unit that rotates the drive shaft. The design of the second flow path member is inclined with respect to the exhaust gas flow direction, optimizing the heat recovery process.

The exhaust heat recovery apparatus consists of a housing with a heat exchange flow passage that branches from the main exhaust gas flow passage. This apparatus converges back to the main passage through a heat exchanger. The valve mechanism in this apparatus includes a valve pipe and a rotating valve body that allows exhaust gas to flow into the heat exchange flow passage. This innovative design ensures efficient heat recovery from exhaust gases, contributing to improved energy utilization.
