Cooling system, especially for electrical appliances

Abstract

In order to cool an electrical appliance, a fuel storage tank ( 1 ) is provided, which has a connection ( 3 ) to a fuel cell ( 2 ) in order to feed fuel to it. Electrical consumers ( 4 ) are connected to the fuel cell ( 2 ). In their operating mode, the electrical consumers ( 4 ) represent heat sources ( 6 ). The electrical consumers are cooled by means of a thermally conductive connection ( 8 ) between heat sources ( 6 ) and a heat sink ( 7 ). The heat sink ( 7 ) results from the withdrawal of fuel from the fuel storage tank ( 1 ) for the operation of the fuel cell. The described cooling works without noise and is therefore particularly suitable for the use in PC systems.

1 ) cooling arrangement, in particular for elecrical appliances with 
 one fuel cell ( 2 ),    at least one electrical consumer ( 4 ), which is connected to the fuel cell ( 2 ) via an electrically conductive connection ( 5 ), and which in its operating mode is a heat source ( 6 ),    a fuel storage tank ( 1 ), which is connected to the fuel cell ( 2 ) for the purpose of feeding fuel into it, and which in its operating state, characterized by the withdrawal of fuel, is a heat sink ( 7 ), and    a thermally conductive connection ( 8 ) between heat source ( 6 ) and heat sink ( 7 ).    
     
     
         2 ) Cooling arrangement according to  claim 1 , characterized by the fact that the electrical appliance is a portable computer system.
