These devices must be portable, light, easy to use and affordable while keeping their cooling and operating temperatures at very specific levels for patient comfort and safety.
While creating the prototype for their device, Aqueduct Medical sought the expertise of Eaton, to aid in designing and optimizing the heat dissipation assembly.
The prototype had very specific design constraints such as to be easy to use and be unobtrusive in a patient’s home. It also had to be affordable while maintaining proper temperatures to deliver the maximum therapeutic use.
Noise, weight, power consumption and cost all needed to be kept carefully regimented as well as temperature. The industrial design also had to conform well to how the prototype worked and operated.
Eaton engineered and optimized the heat dissipation assembly for prototyping. The cooling solution was designed with thermoelectric modules placed on a cold plate and an active cooling consisting of heat sinks and a fan while complying with the design constraints of:
Fluid Flow
During the design and optimization process, the cost for a mass production version of the cooling solution (heat sink, cold plates) were estimated.
Eaton managed to keep the cost close to the targeted price, the acoustics below the target and provide a simple, effective and compact cooling solution.
