Sorption cooling element with regulating organ and additional heat source

摘要

Cooling element is hermetically surrounded by a gas-tight multiple layer film to enclose a regulating unit (3), a steam passage (4) and a vaporizer (2). The vaporizer and the steam passage are flexible and the steam is only able to pass via the regulating unit to an absorbent (1). An independent claim is also included for a method for evacuating a cooling element. Preferred Features: The regulating unit contains a valve (6) which is operated by deforming the multiple layer film and a thermostatic valve. The thermostatic valve contains a regulating body made from a bimetal and is in thermal contact with the steam.
