Abstract
The present invention relates to apparatus for cooling an object which is exposed to high temperatures and particularly to cooling by heat transfer to a liquid. According to the invention an internal hose is disposed in a fluid conduit. The hose is permeable to the coolant liquid which is circulated therein so that there is created a substantially stagnant fluid boundary layer between the walls of the tube and the internal hose for efficient heat transfer to the circulating fluid within the hose.
