The following are some ways to cool water using thermoelectric cooler without ice formulation on the cold side of the thermoelectric module which acts as a thermal insulator:
- Using a direct cooling heat exchanger with a circulating pump with flow control to reduce residence time which may lead to ice formation and flow path blockage. A temperature sensor placed on heat exchanger output will be used to control the flow.
- Using thermoelectric module with magnetic stirring (see the proposed design below)
- Using swirling jets generated by a small circulating pump
- Using more than one thermoelectric cooler with duty cycling (on and off control) to enable cold side deicing
- Using stirring impeller
