Various embodiments of microelectronic package cooling assemblies are described. Those embodiments include a cooling assembly comprising an array of vertically separated micro channels coupled to a heat spreader, wherein the heat spreader is finless, and wherein each inlet micro channel has two adjacent outlet micro channels. A distance between individual vertically separated micro channels comprises less than about 20 microns, and a heat pipe is embedded in the heat spreader.

A thermoelectric cooler assembly comprises a cold plate, a first thermoelectric cooler, and a second thermoelectric cooler. The cold plate has a first side and a second side. The first thermoelectric cooler is in thermal communication with the first side of the cold plate, and the second thermoelectric cooler is in thermal communication with the second side of the cold plate. A heat exchanger assembly is also disclosed.

Embodiments of semiconductor chip assemblies, and methods are shown that include adhesive thermal interface materials between a heat spreader and a semiconductor die. Assemblies and methods are shown where the heat spreader is not adhered to a substrate beneath the semiconductor die.

Low profile heat spreader and methods

Thermal management systems for semiconductor devices are provided. Embodiments of the invention provide two or more liquid cooling subsystems that are each capable of providing active cooling to one or more semiconductor devices, such as packaged processors. In operation, a first liquid cooling subsystem can provide active cooling to the semiconductor device(s) while the second cooling subsystem is circulating a heat transfer fluid within its own subsystem. The second liquid cooling subsystem can be then switched into operation and provides active cooling to the semiconductor device(s) while the first cooling subsystem is circulating heat transfer fluid within its own subsystem. In alternate embodiments, the heat transfer fluid remains in the subsystem, but does not circulate within the subsystem when the subsystem is not providing cooling to the semiconductor device(s). The subsystems comprise heat dissipation units. The switching between cooling systems allows the semiconductor device(s) to be maintained at a lower operating temperature than if switching between cooling subsystems were not employed.

Transient thermal management systems for semiconductor devices

A method and apparatus for removing vapor inside a liquid pump at the start up operation of the pump. In addition, a method and apparatus for removing liquid inside a compressor at the start up operation of the compressor. The pump and compressor each include a sensor attached to them that determines the physical state (i.e., liquid or vapor) of a material inside the pump or compressor. If vapor is detected inside the pump, a thermoelectric module connected to the pump is powered to condense the vapor into a liquid. Likewise, if liquid is detected inside the compressor a heater connected to the compressor is powered to evaporate the liquid into a vapor. After the state of the material inside the pump or compressor is changed, the pump or compressor is powered up for operation in a cooling system.
