Introduction

Yuji Kohashi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of heat transfer technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.

Latest Patents

Kohashi's latest patents include a scale thickness measuring method and an insertion-hole blockage-rate evaluation system. The scale thickness measuring method involves using an eddy-current probe to measure the thickness of attachments on a heat transfer pipe. This method calculates a reference point by determining the difference between axial and circumferential components of the magnetic field. The probe is then moved within the pipe to obtain a drift amount, which is used to calculate the thickness of the attachments based on a pre-established calibration curve.

The insertion-hole blockage-rate evaluation system is designed for heat exchangers and includes a three-dimensional display of a tube support plate with an insertion hole. This system color-codes the diagram based on the blockage rate of the insertion hole, providing a clear visual representation of potential issues.
