This heat exchanger printed from pure copper has more functions than simply removing the heat from a medium. It is also a liquid mixer with two separate inlets at the bottom made from thin ducts (1 mm), which connect to form an outlet at the top of the component. The core enables the medium to be cooled. The side has two connections for a coolant that removes the heat from the mixed liquid. The component is printed using pure copper ETP (CW004A) with a conductivity of 101% IACS, 394 W/(m*K) heat conductivity, and a part density of 99.9%, on a TruPrint with a TruDisk 1020 Green with 515 nm wavelength.
