Mask cooling

---

Introduction

This wiki page will contain a study of the different possibilities of cooling the UV-mask.

---

Requirements

• Heat removal: xx W/min
• Low profile
• Power consumption
• Noise level
• Integratable in a mask
• Robust

Project documents

Peltier elements

• Razer phone cooler chroma
  • Peltier element with fan. Originally to cool down a mobile phone (Dec.2021)

Fan types

• Aeronest - A ventilation kit for your Covid mask (Dec.2021)

• Sunon mighty mini fan and blower

• Sepa micro fans

  • Very small but likely not enough flow.

• Delta fans

  • Quite a few different types
  • E.g. Delta Electronics BFB04512HHA-DV52, 45 x 10.3mm
    • Blows quite nicely even through a long tube. PWM speed control. 36 dBA which is not super-loud but still quite noticeable at full speed.

• SEPA HY_45T05A-830 Fan Blower, Radial, 5 VDC, 45 mm, 5 mm, 38 l/min

  • They are thinner but shift nearly as much air albeit with a lower static pressure. They are also quieter (27 dBA). The advantage is they are 5V. Also PWM control.
