Definitions
- a method for cooling a memory module includes providing heatsink.
- the heatsink includes a substantially planar contact portion for forming a thermal contact with the memory module and for mounting the heatsink on the memory module.
- the heatsink also includes one or more formations for emitting heat, the formations for eniitting heat being in thermal communication with the contact portions.
- the method also includes mounting the heatsink on the memory module.
- Figure 1 illustrates an example of a computer system including an array of memory modules
- Figure 2 illustrates an example array of memory modules
- Figure 3 illustrates an example of a memory module and heatsink assembly
- Figure 4 illustrates another example of a memory module and heatsink assembly. While the invention is susceptible to various modifications and alternative forms, specific embodiments are shown by way of example in the drawings and are herein described in detail.
- FIG. 1 illustrates an example of a computer system 10, which includes an array 100 of memory modules 120 such as Dual Mine memory Modules (DIMMs).
- the computer system 10 also includes a circuit board 20 upon which the array 100 is mounted.
- a number of further components 30 are also mounted on the circuit board 20.
- the circuit board 20 is provided wittiin a housing.
- each memory module 120 includes a board which is vertically mounted in a socket 110, which is itself mounted on the circuit board 20. Each board can include contacts for engaging with corresponding contacts of the socket 110. Each board can have a number of memory components mounted thereon.
- the memory components may, for example, comprise solid state memory such as double data rate (DDR) memory. The memory components can be mounted on one or both sides of each board.
- DDR double data rate
- FIG. 2 shows an example of a memory array 100 in more detail.
- the memory array 100 in this example includes four memory modules 120.
- Each memory module 120 includes a board 122, which is vertically mounted in a socket 110.
- the socket 110 is mounted on a circuit board 20.
- the socket 110 is not essential.
- each board 122 has nine memory components 130 mounted on each side thereof making a total of eighteen memory components 130 per board 122. It is apparent from Figure 2 that in the array 100, the memory components 130 are densely spaced. Accordingly, a large number of memory components 130 are located in close proximity to each other and thereby constitute a significant source of heat. Furthermore, since the memory components 130 are densely spaced, the dissipation of heat from the array 100 is hindered.
- any flow of cooling air which is provided to carry heat away from the array 100 can only gain access to the memory components 130 which are positioned towards the centre of the array 100 by flowing in between two adjacent boards 122. Since the space between adjacent boards 122 may be narrow (for example less than 1 millimetre), no substantial flow of air between adjacent boards 122 can occur. Examples of heatsink suitable for facilitating cooling of memory components 130 in an array 100 such as that described in relation to Figures 1 and 2 are described below.
- Figure 3 shows an example of a heatsink and memory module assembly 160.
- the assembly includes a memory module 120 having a heatsink 170 mounted thereon.
- the memory module 120 includes a board 122, which has a plurality of memory components 130 mounted on a either side thereof.
- the board 122 can include contacts for connecting with corresponding contacts in a socket such as the socket 110 shown in Figures 1 and 2.
- the heatsink in this example includes a pair of mutually opposing contact portions 152, which engage with opposite outer surfaces of the memory module 120.
- the contact portions 152 engage with the surfaces of the memory components 130. This allows heat produced by the memory components 130 to be transferred directly to the contact portions 152.
- the heatsink 170 also includes formations 150 for emitting heat.
- the formations 150 in this example are integrally formed with the contact portions 152 and are therefore in thermal communication with the contact portions. In other examples the formations 150 can be formed separately and attached to the contact portions 152 in thermal contact therewith.
- the thermal contact between the formations 150 and the contact portions 152 allows heat acquired by the contact portions from the memory module 120 to migrate into the formations 150. Heat that has migrated into the formations 150 can then be emitted from the formations 150 as thermal radiation and can thereby be carried away from the memory module 120. In some examples, and as will be described below, a flow of cooling air can be provided across the formations 150 to facilitate the dissipation of heat therefrom.
- the contact portions 152 each include a plurality of fingers 156. Each finger engages with a respective memory component 130 of the memory module 120. In other examples, the contact portions 152 may include fingers, which contact with a respective plurality of memory components 130. In other examples, the contact plates 152 are not split into fingers.
- the contact portions 152 form a pair of jaws which are biased towards a closed position to engage with opposite outer surfaces of the memory module 120. Accordingly, when the heatsink 170 is mounted on the memory module 120, the contact portions 152 urge against the opposite outer surfaces of the memory module 120. This has the effect of improving the thermal contact between the contact portions 152 and the surfaces of the memory module 120. This also has the effect of the facilitating the mounting of the heatsink 170 on the memory module 120 and of preventing dislodgement of the heatsink 170 once it is mounted.
- a thermally conductive adhesive can be provided at the interface between the contact portions 152 and the opposite surfaces of the memory module 120.
- the formations 150 in this example include two ti in pieces of thermally conductive material 154, which are each folded in a number of places so as to increase their surface area without significantly increasing the overall physical dimensions of the formations 150.
- the two pieces of material 154 are joined together in a number of places 164 by, for example, welding or using a thermally conductive adhesive.
- the thin cross section of the pieces of material 154 and of the contact portions 152 provide a number of advantages. Firstly, the width of the heatsink and memory module assembly 160 is substantially the same as the width of the memory module 120 without the heatsink 170 mounted thereon.
- the ability of the memory module 120 to be mounted adjacent other components is not impeded. Accordingly, an array such as the array 100 shown in Figures 1 and 2 is readily modifiable by mounting a heatsink 170 such as that shown in Figure 3 on each memory module 120, whereby heat dissipation from the array 100 is significantly enhanced. In this manner, memory modules in a memory array can be densely spaced without over-heating, thereby saving space on a circuit board and in a computer system, where space is usually at a premium.
- the thin cross section of the pieces of material 154 of the formations 150 present minimal resistance to the flow of cooling air in a direction shown generally in Figure 3 by the arrow labelled B.
- a fan of the computer system can be aligned to direct a flow of cooling air over the heatsink 150 in a direction substantially parallel to the direction shown by the arrow labelled B, thereby maximising the efficiency of the cooling provided by the heatsink 150.
- Typical construction materials for the heatsink 170 include beryllium, copper or graphite. Beryllium copper is a springy metal and is therefore suitable for biased contact portions 152 as described above.
- FIG 4 shows another example of a heatsink and memory module assembly 260.
- the memory module 120 in this example only has memory components mounted on one side of the board 122.
- the heatsink includes a single contact portion 252, which as described above has a number of finger 256.
- the heatsink also includes formations 250 for emitting heat.
- the formations 250 are formed from a this piece of material 254 such as Beryllium copper or graphite as described above.
- the thin piece of material 254 can be formed integrally with, or attached to the contact portion 252.
- the contact portion can be mounted on the heatsink by, for example, providing a thermally conductive adhesive between the contact portion 252 and the memory module 120 (for example in the region indicated by the numeral 258 in Figure 4). This would also provide a good thermal contact between the contact portion 252 and the memory module 120. Alternatively, or in addition, clips or other fixings could be provided for mounting the heatsink 270. Heatsinks such as that shown in Figure 4 may also be used in conjunction with memory modules having boards with memory components mounted on both sides (such as is shown in Figure 2). Other example configurations for formations 150 are envisaged. For example, the formations may include one or more fins. The fins may be folded in a manner analogous to the folds of the thin pieces of material 154 shown in Figure 3.
- the fins may have a number of different profiles, for example sinusoidal or U-shaped.
- the fins of heatsinks which are mounted on neighbouring memory modules can be arranged to alternate out of phase (for example 180 out phase), or they can be chosen to have a different pitch. This can allow the spacing between the fins to be selected according to system requirements.
- the heatsinks described in the examples given above provide a number of further advantages. Since the temperature of the memory modules upon which the heatsinks are mounted is reduced due to the enhanced cooling effect, this can allow memory modules to be used in environments having a high ambient temperature and/or low ambient air pressure (for example at raised altitudes).
- the increased cooling effect may allow reduced specification fans to be provided in a computer system (since a weaker flow of cooling air can suffice), whereby the overall cost of the computer system is reduced.
- different configurations of memory modules can be included in a memory array without significantly effecting the cooling of those memory modules. This is because when heatsinks such as those described above are used, the majority of cooling power provided for memory modules is provided by the heatsinks. This being the case, the flow of cooling air over the heatsinks would not be significantly affected by differing dimensions of the memory modules upon which they are mounted.
