Structural Effects of 3D Spacer Fabrics on Cooling Efficiency

Evaporative cooling fans are being increasingly used in the industrial and livestock industries for air cooling. This process utilizes the vaporization cooling phenomenon when water evaporates. Most cooling filters for evaporative cooling fans consist of paper filters. However, the paper filter has a fatal disadvantage in that it has low durability and poor reusability because of contamination arising from the growth of fungi and moss and the fact that it is difficult to wash. In this study, a polyethylene terephthalate (PET) monofilament-based 3D spacer fabric was fabricated and examined for use as a cooling pad to replace paper filters. In addition, the 3D spacer fabrics were fabricated by making monofilaments with various types of cross-sections, as well as different types of circular shapes. The water absorption, drying rate, moisture evaporation, and cooling efficiency of the 3D spacer fabric were controlled by adjusting the cross-sectional shape of the filaments. In addition, the effect of air volume on the cooling efficiency was determined.
