Additive manufacturing by Belgian thermal management design company Diabatix: Heat transfer efficiency of liquid nitrogen radiators has increased by approximately 60%
Created on 09.25
I.Company Overview
Diabatix is a Belgian SaaS company that leverages generative design to provide thermal management solutions for high heat-density electronic devices. Diabatix has utilized additive manufacturing across multiple projects.
II.Liquid Nitrogen Cooler
At the request of SkatterBencher and ElmorLabs, Diabatix collaborated with 3D Systems to produce an additively manufactured pure copper liquid nitrogen cooler for ASUS ROG team.
It features a unique tree-like heat dissipation structure, with a thicker base and a thinner top, which optimizes the distribution of heat.
The design without a horizontal surface enables the vapor generated by liquid nitrogen to flow smoothly along the vertical pipe wall. The thermal resistance is as low as 0.011K/W, and the heat transfer efficiency is improved by approximately 60%. The cooling speed is three times faster than that of the traditional Volcano.
This product helped the ASUS ROG team overclock the Intel Core Ultra 9 285K processor to 7.5GHz, setting 19 world records and achieving the top position in 31 benchmark tests.
III. CPU Cooler
Diabatix collaborated with Belgian Amnovis to design an additive manufacturing CPU cooler.
Compared with traditional skived heat sinks, the additive manufacturing products achieve complex topological optimization structures, with the thermal resistance reduced by 55% and the pressure drop decreased by 11%.
IV. Motor Cooling Jacket
Diabatix assisted the Belgian student electric racing team in designing an additive manufacturing motor cooling jacket.
The racing cars of this team participating in Formula Student (the world's largest engineering student competition) are equipped with four high-power motors and require effective cooling through a water cooling system. The additive manufacturing cooling jacket improves the cooling capacity while keeping the pressure drop at the lowest level.
