Air bearing heat exchanger
| DWPI Title: Heat exchanger for extracting heat from an underlying substrate, comprises a baseplate that has a shaft that extends orthogonally from an upper surface of the baseplate at a center of the baseplate, where channel extends from outer surface |
| Abstract: The various technologies presented herein relate to fabrication and operation of a heat exchanger that is configured to extract heat from an underlying substrate. Heat can be extracted by way of an air gap formed between an impeller and a baseplate. By utilizing a pump to create an initial air gap that is further maintained by rotation of the impeller relative to the baseplate, a spring can be utilized that can apply a force of greater magnitude to the impeller than is used in a conventional approach, thus enabling the weight of the impeller to be negligible with respect to a width of the air gap, thereby conferring the desirable feature of orientation independence with respect to gravity with no performance degradation. |
| Use: Heat exchanger for extracting heat from an underlying substrate. |
| Advantage: The heat exchanger comprises a baseplate that has a shaft that extends orthogonally from an upper surface of the baseplate at a center of the baseplate, where channel extends from an outer surface of the baseplate to the upper surface of the baseplate and heat sink impeller has a first surface that faces the upper surface of the baseplate, and thus enables to keep a low thermal resistance and avoids performance loss and maintains the air gap between the baseplate and the heat sink impeller to establish a hydrostatic air bearing. |
| Novelty: The heat exchanger comprises a baseplate (120) that has a shaft that extends orthogonally from an upper surface of the baseplate at a center of the baseplate. A channel extends from an outer surface of the baseplate to the upper surface of the baseplate. A heat sink impeller has a first surface that faces the upper surface of the baseplate. The first surface has an area. Multiple vanes extends from the second surface. The pump is connected to the channel at the outer surface of the baseplate. The pump (170) is configured to generate a first air flow to create an air bearing between the heat sink impeller (110) and the baseplate. |
