Research on Coolant Using Nano Additives and Heavy Water

Article of Honda R&D Technical Review F1 Special (The third Era Activities)

Summary

Research was done on coolants with the objective of increasing automobile radiator cooling efficiency and contributing to aerodynamics by enhancing the thermophysical properties of engine coolants.
The research confirmed the effectiveness of adding nano additives to enhance heat conductance, as well as using heavy water in solvent to increase specific heat of the coolant. Because evaluations of cooling performance in actual engines have not shown a clear difference from conventional coolants using water, a precise heat transfer measurement technology was established to clarify the factors affecting heat transfer, and from this, directions were established for the development of engine coolants.
