Circulating Water - an overview | ScienceDirect Topics

The process of circulating water through tubes embedded in a LCG is referred to as 'convective cooling' (Burton and Collier, 1964; Flouris and Cheung, 2006), and also as 'conductive cooling' (Nunneley, 1970; Xu et al., 1999). Figure 12.1 shows the heat-exchange processes that may take place in a water-perfusion garment (WPG) or in a liquid-cooling garment (LCG).
