Abstract
A heat sink assembly comprises a pair of extruded heat sinks (1, 2) each having fins and a re-entrant slot (6, 7), and a connector (5) having respective portions (12, 13) adapted to engage in the slots. <IMAGE>
Description
Heat Sink Assembly
This invention relates to heat sinks and has particular reference to joining heat sinks together.
Extruded heat sinks are well known. The heat sinks essentially comprise a planar base with a series of projecting fins along which air is free to pass to remove heat normally generated by an electronic component. Such heat sinks are sometimes attached to the rear top or sides of electronic apparatus and in some cases they are required to have aesthetic qualities as well as functional qualities.
In some cases there is a need to locate the maximum quantity of heat sink surface on an electronic component system box and this has led to the need to slice and/or join existing heat sinks which can cause inconvenience and result in a costly and unsightly assembly.
By the present invention there is provided a kit of parts for a heat sink assembly comprising a pair of extruded heat sinks, each heat sink having a base and fins extending away from the base, each heat sink having a re-entrant slot on one side at least of the heat sink, there being provided a connector adapted to engage each re-entrant slot of two adjacent heat sinks to form an interconnection therebetween.
The extruded heat sinks may be made of aluminium or an aluminium alloy. The re-entrant slot may be provided on the side of the heat sink or may be provided on the underside of the heat sink or may be provided on the top of the heat sink. The re-entrant slot may be provided on a raised portion of the inside of the heat sink.
The connector may be provided with no fins, or one or more fins. The connector may be of generally U-shape, having a base of the same thickness as that of the main heat sinks, and may be of sufficient width to accept various typical electronic devices on its upper surface. Each leg of the U may be provided with a male portion adapted to engage a re-entrant slot in the side of a heat sink.
By way of example embodiments of the present invention will now be described with reference to the accompanying drawings, of which:
Figure 1 is a cross-section of one form of connector
with two edges of adjacent heat sinks; and
Figures 2 and 3 are cross-sections of alternative
forms of-connector with two edges of adjacent
heat sinks.
Referring to Figure 1 this shows a pair of heat sinks 1, 2 which are shown with their right hand edge 3 and their left hand edge 4 interconnected by means of a connector 5. The right hand edge of heat sink 1 has a re-entrant slot 6 and the left hand edge of heat sink 2 has a re-entrant slot 7. The connector 5 is of generally
U-shape with a base 8 and a central fin 9. Each leg 10 and 11 of the U-shaped connector has a male portion 12, 13 which is slid into the re-entrant slots 6 and 7.
It will be appreciated that the fin 9 may be dispensed with if required and electronic devices may then be mounted on the connector.
The connector illustrated in Figure 1 enables a firm connection to be made between the two heat sinks 1 and 2 so that modular sized heat sinks can be made up to any required width. The connector enhances the aesthetics of an assembly of adjacent heat sinks, adds rigidity to the assembly by making a firm interconnection therebetween and increases the thermalperformance of the heat sinks by increasing their effective surface area.
In the design illustrated in Figures 2 and Figure 3 the aesthetic appearance of the interconnected heat sink is even further increased. In this arrangement heat sink members 14 and 15 are interconnected by a connector 16 which slots into re-entrant slots 17 and 18 located on the inside of the heat sinks 14 and 15. With such an arrangement, therefore, the upper surface of the heat sink merely appears to have a continuous run of fins.
It will be appreciated that any desired form of connector could be used and that the detailed forms shown in
Figures 1, 2 and 3 are by way of example only.
