Introduction

Yoshihisa Eto, an inventive mind hailing from Konan, Japan, has made significant strides in the field of heat exchanger technology. With a total of nine patents to his name, Eto's innovations aim at improving product quality and efficiency in thermal systems.

Latest Patents

Among his recent patents, one notable invention is a **Method of Manufacturing Heat Exchanger**. In this innovation, a heat exchange tube is created using a sheet member that is not clad with a brazing material layer. By incorporating bonding regions where the ends of the sheet member overlap and are brazed with a brazing material, the structure minimizes the dispersion of the brazing material during the brazing process. This design effectively reduces the likelihood of dissolution due to erosion, ensuring the desired quality attributes, such as corrosion resistance—even when utilizing tube materials with thinner walls.

Additionally, he developed a revised **Heat Exchanger** characterized by a four-pass structure. This innovative design includes two rows of tubes along with an upper and lower tank portion that communicate efficiently. Notably, the inflow port is smaller and positioned higher than the outflow port, optimizing the overall performance and functionality of the heat exchanger.
