Heat exchanger : Scalp Cooling Cap, WorlWide patent, WO2016/046534 A1 ― 2016-03-31

A heat exchanger, and method of manufacture of a heat exchanger configured to be placed into contact with an object to regulate the temperature of the object. The heat exchanger comprises a layer of material defining a passage through which a heat transfer fluid may flow.The material layer has a first side for contact with the object, and a second side which, in use will face away from the object. The first side has a relatively high coefficient of thermal conduction. The second side has a relatively low coefficient of thermal conduction compare to the first side.
