Abstract 1,067,195. Printed circuit assemblies. T. M. ELFVING. Oct. 29, 1963 [Oct. 29, 1962], No. 42698/63. Heading H1R. [Also in Division F4 ] A sheet 101 carrying a printed or painted circuit 102 is secured to one side of a double-walled aluminium coding panel which is formed with a plurality of interconnected passages 104 partly filled with refrigerant. A further sheet 105 is moulded to the other side of the panel, sheets 101 and 105 being provided with apertures which are aligned with and smaller than apertures 108 in the panel. Electrical connections may thus be made through the apertures between the circuit and electrical components mounted on opposite sides of the panel. The sheets 101, 105 may be formed of plastics or ceramic material, e.g. aluminium oxide or beryllium oxide, the surface of the latter material being metallized with silver, nickel or ridymanganese where necessary for soldering.
IN COMBINATION A HEAT TRANSFERRING PANEL COMPRISING FIRST AND SECOND MEMBERS BONDED OVER PREDETERMINED AREAS TO FORM A DOUBLE WALLED HERMETICALLY SEALTED PANEL HAVING A PLURALITY OF INTERCONNECTED PASSAGES, A REFRINGERANG PARTLY FILLING THE PASSAGES IN SAID PANEL, SAID PANEL COMPRISING A HEAT ABSORBING PORTION AND A HEAT DISSIPATING PORTION, SAID HEAT DISSIPATING PORTION BEING SPACED FROM THE HEAT ABSORBING PORTION AT A HIGHER HORIZONTAL LEVEL AT LEAST ONE HEAT DISSIPATING ELECTRICAL COMPONENT, MEANS FOR TRANSFERRING HEAT FROM THE COMPONENT TO THE HEAT ABSORBING PORTION OF THE PANEL WHEREBY HEAT TRANSFERRED FROM SAID OBJECT TO SAID HEAT ABSORBING PORTION IS TRANSFERRED TO THE REMOTE HEAT DISSIPATING PORTION BY THE REFRIGERANT, AN EXTENDED SURFACE HEAT DISSIPATING MEANS, A THERMOELECTRIC HEAT PUMP CONNECTED BETWEEN THE HEAT DISSIPATING PORTION OF SAID PANEL AND SAID EXTENDED SURFACE HEAT DISSIPATING MEANS TO TRANSFER HEAT FROM THE HEAT DISSIPATING PORTION OF THE PANEL TO THE EXTEND SURFACE HEAT DISSIPATING MEANS AND MAINTAIN THE HEAT DISSIPATING PORTION OF THE PANEL AT A TEMPERATURE BELOW THE TEMPER
