Description

BACKGROUND

The invention relates generally to thermal management systems, and more particularly to thermal management systems for use in microelectronic devices.
Thermal management is becoming an increasingly significant concern in the microelectronics industry. Non-limiting examples of microelectronic devices include printed circuit board computers, programmable logic controllers (PLCs), operator interface computers, laptop computers, cell phones, personal digital assistants (PDAs), and personal pocket computers. Such devices generate waste heat during normal operation that must be dissipated for desirable performance and reliability of microelectronic components in the device.
Several technologies have been employed to remove heat from microelectronic devices. An example includes forced air cooling via conventional cooling fans and heat sinks. Heat sinks conduct thermal energy away from the devices and transfers the thermal energy to air circulated by cooling fans. However, cooling fans use an undesirable amount of energy, create audible noise and have space limitations.

The elastomeric tab 42 is attached to the mounting posts 62 via the tab pinch clips 46 such that the cooling device 12 is mounted in a plane perpendicular to a plane of the substrate 18. This results in jet streams blown in a direction 64 toward the substrate 18.
FIG. 5 schematically illustrates a mounting apparatus 80 for the cooling device 12 in FIG. 1. The mounting apparatus 80 may mount the cooling device 12 in a planar orientation with respect to the substrate 18. The mounting apparatus 80 includes a connector formed in a shape of an E-clip 82 extending outwardly from the cooling device 12. A mounting post 86 coupled to the E-clip 82 mounts the cooling device 12 at an angle to the substrate 18.

The compliant material 104 includes an orifice 108 that provides a channel for a jet stream.
FIG. 7 is a schematic illustration of a top view of an exemplary cooling device 100. The cooling device 100 includes an active material 110 bonded to a thin plate or disk 102. In a particular embodiment, the active material 110 may be electrically stimulated to cause an out of plane deformation resulting in a jet of air through an orifice (not shown).
Examples of a suitable active material 110 include piezoelectric material, magnetostrictive material (magnetic fields from coils attract/oppose one another), shape-memory alloy, and motor imbalance (motor with a mass imbalance creates oscillatory motion). Within the subset of piezoelectric materials, suitable active materials include bimorph piezoelectric configurations, where two piezo layers are energized out of phase to produce bending; thunder configurations, where one piezo layer is disposed on a pre-stressed stainless steel shim; buzzer element configurations, where one piezo layer is disposed on a brass shim; and MFC configurations, where a piezo fiber composite on a flexible circuit is bonded to a shim. The active material 110 may also incorporate a ceramic material.

In an example, the compliant material 104 includes an elastomeric material. An active material 110 as referenced in FIG. 7 is bonded to at least one of the plates or disks 102. In a particular embodiment, the active material 110 is bonded to the plate or disk 102 in one assembly step, then the combination of 110 and 102 are positioned in a pattern via a pick and place automated system. The compliant material 104 is further dispensed at a controlled rate onto the plate or disk 102 such that a desirable thickness is obtained and the cooling device 100 may be tuned to a desired structural frequency. The compliant material 104 also includes an orifice or opening 108 (FIG. 6) that provides a channel for a jet stream between the chamber 106 and an exterior environment. A stress on the plate or disk 102 created by the active material 110 in response to an electrical stimulus, causes an outward flexing, resulting in a volume change in the chamber 106 and an influx of ambient air into the chamber 106, and then inwardly, thereby ejecting the ambient air from the chamber 106 via the orifice 108. It should be appreciated that the active material 110 may be positioned on an inner surface of the plate or disk 102 instead of, as shown in FIG. 8, an outer surface.

While the invention has been described in detail in connection with only a limited number of embodiments, it should be readily understood that the invention is not limited to such disclosed embodiments. Rather, the invention can be modified to incorporate any number of variations, alterations, substitutions or equivalent arrangements not heretofore described, but which are commensurate with the spirit and scope of the invention. For example, while embodiments of the invention describe the use of multiple mounting posts for use with a single cooling device, it should be appreciated that a single mounting post with branching mounting arms may be used. Further, although the mounting posts are described as being stiff and unmovable, it should be appreciated that the mounting posts may be stiff but pliable to enable one to tune particular cooling devices to a specific angle relative to the plane in which the substrate exists. Alternatively, the mounting posts may incorporate a mechanism by which the angle for any particular cooling device can be manually indexed. Additionally, while various embodiments of the invention have been described, it is to be understood that aspects of the invention may include only some of the described embodiments.
