Abstract
The differing operating temperatures of the DePFET sensor and the closely located Front-End Electronics require a thermal solution with two separate cooling chains for the Camera Head of the WFI instrument. The chosen solution minimizes the total radiator area needed for Camera Head cooling. This paper explains the thermal design and cooling concept, which includes using highly conductive graphene thermal straps and considers the parasitic heat exchange between the two cooling chains due to the large number of bond wires and radiative heat exchange.
