Title: Norio Takashima and a Synthetic-Resin-Tank Heat Exchanger.

Introduction

Norio Takashima is an inventor associated with Konan, Japan, and Diesel Kiki Co., Ltd. His work includes a heat exchanger designed for applications such as car heaters.

Latest Patents

The available information identifies one patent associated with Takashima: “Heat Exchanger with Fluid Tanks Made of Synthetic Resin.” The invention uses tubes and attached fins extending between two fluid tanks. Each tank consists of inner and outer synthetic-resin elements. The tube ends pass through gaskets and are joined to the inner tank element through tube-expansion working, while the outer element is joined along the inner element’s corresponding edges.

Partition walls between the tank elements separate the inlet and outlet chambers, forming a fluid-tight division. The design aims to provide a compact, lightweight heat exchanger with adequate mechanical strength that is straightforward to assemble and resistant to rust and corrosion. Takashima is credited with 1 patent in the information provided.
