Design/production of corrosion resistance polymer heat exchanger and analysis/evaluation of thermophysical property
Client / Market
- Market for low pressure heat exchanger for operating under exposure to corrosion environment (seawater heat exchanger substitution)
Necessity of this Technology
- Corrosion occurs for existing heat exchangers using seawater; existing titanium heat exchangers are expensive.
- Replacement with highly conductive polymer composite materials is expected to reduce the weight and production and maintenance cost significant.
- It is difficult to find a heat exchanger type heat sink.
- With the need for a non-metal heat exchanger for corrosion prevention, there is a need for development of heat exchanger made of polymer composite material.
Technical Differentiation
- Heat exchanger made of polymer composite is lighter and has higher design formability than existing heat exchanger.
- Technology for material selection, material mixing, and thermophysical properties assessment developed in the design process
Excellence of Technology
- Secured thermal conductivity of 2 W/mK
- A heat exchanger for compactness improvement is designed and was confirmed to be able to replace a metal heat exchanger at a low Reynolds number.
- Plate type heat exchanger prototype made with an injection mold
Current Intellectual Property Right Status
