Abstract
Description
Die Erfindung bezieht sich auf ein Gehäuse bestehend aus einer ersten Gehäusehälfte, in der eine Leiterplatte angeordnet ist, und einer zweiten Gehäusehälfte, wobei die beiden Gehäusehälften über eine Rastverbindung miteinander verbunden sind. Dabei dient der Boden der zweiten Gehäusehälfte als Kühlkörper für zumindest ein auf der Leiterplatte angeordnetes wärmeerzeugendes Leistungsbauelement.The Invention relates to a housing consisting of a first Half of the housing, in a circuit board is arranged, and a second housing half, wherein the two housing halves over one Snap connection are connected to each other. The floor serves here the second half of the case as Heat sink for at least a heat-generating power component arranged on the circuit board.
Ein
derartiges Gehäuse
ist aus der
Aufgabe der Erfindung ist es, eine Gehäuseanordnung bestehend aus zwei über eine Rastverbindung verbundenen Gehäusehälften zu schaffen, bei der Wärme in effektiver Weise über einen Gehäuseboden abgeführt wird, wobei auf Abstützelemente für die Leiterplatte verzichtet werden kann.task the invention is a housing arrangement consisting of two over to create a snap-in connection connected housing halves at Warmth in effectively about a case back dissipated being, with support elements for the printed circuit board can be dispensed with.
Erfindungsgemäß liegt
der Gehäuseboden, um
für eine
Wärmeableitung
zu sorgen, nicht mehr unter Vorspannung an der Leiterplatte an.
Stattdessen ist zwischen der Leiterplatte und dem Boden der zweiten
Gehäusehälfte im
zusammengebauten Zustand der beiden Gehäusehälften ein Spalt vorgesehen
ist, damit wird vermieden, daß die
Leiterplatte gegen den Gehäuseboden
drückt,
wodurch sichergestellt wird, daß die
beiden Gehäusehälften soweit
zusammengefügt
werden können
bis die Rastverbindung bewirkt ist. Damit ersetzt der Spalt das
elastische Material im Fügebereich
gemäß
Vor dem Zusammenfügen der beiden Gehäusehälften wird dabei die Wärmeleitpaste in Form einer Raupenstruktur und/oder in Form von einzelnen Inseln auf den Gehäuseboden aufgebracht, wobei die Höhe der aufgebrachten Wärmeleitpaste gegenüber dem Gehäuseboden größer ist als der Spalt, der zur Bewirkung der Rastverbindung (d.h. zum Schließen des Gehäuses) notwendig ist. Wenn nun die beiden Gehäusehälften bis zur Bewirkung der Rastverbindung zusammengefügt werden, drückt die dem Leistungsbauelement abgewandte Seite der Leiterplatte auf die Wärmeleitpaste, da die Höhe der aufgebrachten Wärmeleitpaste größer ist als das Spaltmaß, wodurch die Wärmeleitpaste lateral zwischen der Leiterplatte und dem Gehäuseboden verteilt wird.In front assembling of the two housing halves the thermal paste in the form of a caterpillar structure and / or in the form of individual islands on the case back applied, the height the applied thermal paste across from the case back is bigger than the gap that is used to effect the locking connection (i.e. to close the case) necessary is. If now the two housing halves until the snap connection is effected together be pressed the side of the circuit board facing away from the power component the thermal paste, because the height the applied thermal paste is bigger than the gap dimension, causing the thermal paste is distributed laterally between the circuit board and the housing base.
Da die Wärmeleitpaste sich bei Druckbeaufschlagung lateral zwischen der Leiterplatte und dem Gehäuseboden bei gleichzeitiger Auftragshöhenreduzierung verteilt, wird der Aufbau einer Vorspannung vermieden. Damit kann auf zusätzliche Abstützelemente für die Leiterplatte verzichtet werden.There the thermal paste between the PCB and when pressurized the case back with simultaneous order height reduction distributed, the build-up of a bias is avoided. So that can on additional support elements for the PCB can be dispensed with.
