Patent ID: 8508934

Claim:
An aircraft signal computer system comprising: a plurality of modular signal computer units which are each arranged in a housing, and a liquid cooling device for cooling the modular signal computer units, the liquid cooling device comprising a coolant line, which is connectable to a central liquid cooling system of an aircraft in order to supply a liquid coolant medium at a desired low temperature to the liquid cooling device, and the coolant line of the liquid cooling device being thermally coupled with outer surfaces or outer surface sections of the housings of the modular signal computer units in order to dissipate heat from the modular signal computer units, wherein a heat-emitting component of a modular signal computer unit is in thermal contact with a coolant bath which is thermally coupled to the coolant line of the liquid cooling device, the heat-emitting component of the modular signal computer unit being in thermal contact with a substrate which on account of capillary action is designed to conduct coolant medium from the coolant bath along a surface of the component.
