156B Week 2

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• Design cold side experimentation - Josh, Jocelyne, Vlad

• Start experimentation on cold side - Edgar, Vlad

• Design small tube manifold - Josh

• Run more hot side tests - Tyler, Vlad

• Get flow sensor working - Edgar

• Calculate power draw from PWM equipment - Jocelyne

• Process data from hot side testing - Tyler

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

Zoom - 01/08/2021

• The sponsor mentioned he had spare parts from the previous project

  • • Edgar picked up the parts from the sponsor (01/12/2021)

• Commented on hot side test, mentioned that we may lose water over time in our loop due to the permeability of the tubing

  • • Together we decided we can use a small bladder in the final design as a water reservoir

• Commented on hot side test, mentioned that moving the pump in front of the radiator would be more ideal

  • • Modified test accordingly

• The sponsor asked us to keep work shared at a minimum & to keep the website private

  • • For the final published website, we will be sure to be discreet about proprietary information

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

Zoom - 01/07/2021

• The instructors reminded us to bring up a possible alternative to the sponsor: using a compressor-based system instead of TECs

  • • Discussed with sponsor, he indicated that he wants us to proceed with TEC devices but that he will keep that in mind for future testing

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• No technical comments at the moment.

Risks and Areas of Concern

• Not achieving the desired thermal resistance value of water block from hot side testing.

  • • We would have to redesign the water block.

• Not achieving an adequate thermal resistance from the radiator, for reasonable fan speeds

  • • May have to select a thicker radiator.

Resources or Information Required but not Available

• MAE 156B Spring 2020: Personalized Thermoregulation

  • • Instructor mentioned looking at their project for TEC power regulation via PWM.
