Abstract:
Kühlkörper (30) zur Wärmeableitung von einer elektronischen Baueinheit (12, 28), mit einem wärmeleitenden Grundkörper (14), der eine Ausnehmung (18) aufweist, und einem in der Ausnehmung (18) angeordneten wärmeleitenden Medium (16), das mit dem Grundkörper (14) in wärmeleitendem Kontakt steht, wobei das wärmeleitende Medium (16) so ausgebildet und angeordnet ist, dass die elektronische Baueinheit (12, 28) bei bestimmungsgemäßer Kopplung mit dem Kühlkörper (30) mindestens teilweise in die Ausnehmung (18) hineinragt und mit dem wärmeleitenden Medium (16) in wärmeleitendem Kontakt ist.
Abstract:
The invention relates to a transmission-line network of the foam stripline type. To reduce dielectric losses in the foam (6, 7), at least a part of the foam in the region of the stripline (1) is removed such that the wave properties of the transmission-line network are not impaired. Moreover the ducts (9, 10) that are formed may be used for the forced cooling of the stripline (1) using air or another cooling agent.
Abstract:
The invention relates to an electronic device, especially a control device for a motor vehicle's internal combustion engine, with an electronic circuit arranged on a printed circuit board to which is allocated a multi-pin plug which passes through a housing containing the printed circuit board. The proposal is that the printed circuit board consists of at least one rigid region (7) which may be secured to the component bearing the plug, especially a cover (5) of the housing (4), from which starts at least one flexible, curved section (8) of the printed circuit board.
Abstract:
PROBLEM TO BE SOLVED: To provide a main board of a computer, selectively mounting CPU fans different in dimensions. SOLUTION: The main board 1 of the computer includes: a CPU mounting area 10; a plurality of first fixing holes 20 for fixing a plurality of fixed ends of a first fan; and a plurality of second fixing holes 30 for fixing a plurality of fixed ends of a second fan. The plurality of first fixing holes 20 and the plurality of second fixing holes 30 are distributed in the periphery of the CPU mounting area 10, and two connecting lines from the center of one second fixing hole 30 and the center of the first fixing hole 20 adjacent to the second fixing hole 30 to the central point of the CPU mounting area 10 form an included angle.
