Abstract. Aluminum is a commonly used material when cooling channels are required due to its high thermal conductivity and light weight. However, aluminum has a low corrosion resistance which is a key factor to be aware of when a cooling system utilizing water is required. Metal Technology Co. Ltd. (MTC) currently manufactures a variety of aluminum products in which stainless steel (SS) tubes are embedded and bonded with HIP to improve corrosion resistance while maintaining a light weight. As the demand for complex three-dimensional (3D) cooling channels increases, the complexity creates limitations on creating the cooling channels using the current methods and processes. 3D flow paths can be fabricated if SS tubes are bent and then welded together, but the assembly process for HIP is complex. Complex, thin-walled SS flexible tubes are not able to withstand the pressures applied during diffusion bonding. MTC, has successfully developed an alternative for making internal 3D cooling channels with SS flexible tubes.
