Aerospace methodology, applied to industrial heat exchange.

For 24 years, Shanghai Dongrun Heat-Exchanger Co., Ltd. has engineered, manufactured, validated, and delivered custom heat exchangers to Tier-1 OEMs and EPC contractors worldwide.

Founder

Mao Wenzhuo — Founder and Chairman of Shanghai Dongrun Heat-Exchanger Co., Ltd.

Mao Wenzhuo, professor-level senior engineer, founded Dongrun in 2001.

Before founding the company, he spent 19 years at China's AVIC 614 Aero Engine Research Institute — designer, design group leader, and research division director. That aerospace background is the methodological foundation Dongrun brings to industrial heat exchange today: the same rigor that applies to jet-engine cooling applies, in our work, to motor coolers, wind tunnel HX, and gas turbine inlet air cooling.

He chairs the company and leads the technical roadmap. The R&D team he built is the reason custom designs ship with confidence.
