Ghajar [12] proposed a new model to simulate a micro-loop heat pipe with rectangular capillary grooves. The results showed that geometry optimization, particularly, that of the slot dimensions, is necessary to design an improved micro loop heat pipe device.
By careful cutting of capillary grooves into both the opening sash and the frame and a sunk weathered sill to shed any water run off clear of the wall beneath, you can achieve this.
