CROSS-REFERENCE TO RELATED APPLICATIONS This application claims foreign priority benefits under 35 U.S.C. �119 to co-pending German patent application number DE 10 2007 045 733.4, filed Sep. 25, 2007. This related patent application is herein incorporated by reference in its entirety.
BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings are included to provide a further understanding of embodiments of the present invention and are incorporated in and constitute a part of this specification. The drawings illustrate the embodiments of the present invention and together with the description serve to explain the principles in a non-limiting manner. Other embodiments of the present invention and many of the intended advantages will be readily appreciated as they become better understood by reference to the following detailed description. The elements of the drawings are not necessarily to scale relative to each other. Like reference numerals designate corresponding similar parts.
DETAILED DESCRIPTION OF THE INVENTION In the following detailed description reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terminology, such as �top�, �bottom�, �front�, �back�, �leading�, �trailing� etc., is used with reference to the orientation of the figures being described. Because components of embodiments of the present invention can be positioned in a number of different orientations, the directional terminology is used for purposes of illustration and is in no way limiting. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense and the scope of the present invention is defined by the appended claims.
FIG. 3 depict a part of a further example of a heat transfer system 30. In contrast to the heat transfer system shown in FIGS. 1 and 2 the heat transfer system 30 comprises module heat conductors 31 on both sides of the memory modules 3.
With regard to FIGS. 3A and 3B the coupling element 32 is explained, according to one embodiment of the invention. As shown, the coupling element 32 or coupling apparatus secures on one hand the memory module 3 mechanically and provides on the other hand thermal coupling of the module heat conductor 31 with the central heat conductor 33. The coupling element 32 may be pivot-mounted at the central heat conductor 33 so that the coupling element 32 is in thermal and mechanical contact with the memory module 3 in a closed position and is disconnected from the memory module 3 in an open position so that the memory module 3 can be removed out of the socket 4. In the closed position the coupling element 32 may contact a contact surface 36 of the module heat conductor 31.
With reference to FIG. 5A, the coupling element 42 may comprise a first part 42 a which may be permanently connected to the central heat conductor 43 and a removable second part 42 b. The second part 42 b can be fastened to the first part 42 a by for example a clip, bayonet coupling, a bolt connection or as shown here with screws 46. The first part 42 a may have a recess or a bore hole so that it can be put on the central heat conductor 43. Thermally conductive paste may be provided in the bore hole to increase heat transfer between the coupling element 42 and the central heat conductor 43. The first part 42 a may have a recess in form of a half cylinder in its contact surface to the second part 42 b. The longitudinal axis of the recess may be orientated approximately at a right angle with regard to the longitudinal axis of the bore hole for the central heat conductor. The recess may be provided in such a form that the module heat conductor 41 has contact as extensive as possible to the first part 42 a. A corresponding recess is in the second part 42 b provided so that the whole circumference of the module heat conductor 41 is enclosed by the two parts of the coupling element 42 in an assembled state of the coupling element 42.
In the following a change of a memory module 3 is described. To remove the inserted memory module 3 the screws 46 of the corresponding coupling element 42 may be loosened thereupon the second part 42 b is removed whereupon the memory module 3 can be removed from the socket 4. The new memory module 3 may be inserted into the socket 4, in doing so the module heat conductor 41 is moved into the recess of the first part 42 a. Once the memory module 3 is inserted tightly into the socket 4, the second part 42 b is attached to the first part 42 a with use of the screws 46 so that the memory module 3 is now firmly connected to the central heat conductor 43.
