The Wave&rsquo;s pump and heating element. The mechanical design was created with SOLIDWORKS. The device&rsquo;s thermal and fluid analysis was made using ANSYS and COMSOL. While water circulation can remove the heat from the coil, the device had thermal issues with heat building up in other areas, heating the trapped air in two other sections and affecting the components on the PCB. Fluid flow around the coils was predicted with thermal and CFD software in the wet section. The air-filled sections were not modeled. (Image courtesy of Nise Tech.)
