DESCRIPTION OF PREFERRED EMBODIMENTS

All patents, patent applications, and literatures cited or referenced in this description are incorporated herein by reference in their entireties. In the case of inconsistencies, the present disclosure, including definitions and usage, will control.

A device and methods are provided for an up-conversion energy internal cooling of electronic devices such as integrated circuit (IC) chips, which enable efficient cooling of high frequency processing rates, high power and density electronic devices. The up-conversion energy internal cooling IC chips are designed to provide uniform internal cooling with possibility of localized cooling capabilities for “hot spots” regions of IC chips.

The device comprises at least one electronic component 101, an up-conversion medium 102 in which the electronic component is immersed (FIG. 1) or the medium 102 is embedded into the electronic component 101 (FIG. 2), and a power supply 103 to drive charge changes in the electronic component 101. The electronic component is design or selected to emit most of it's electromagnetic energy at a wavelength 1 when the electronic component changes or moves it's charge, and the up-conversion medium is optimized or selected to efficiently absorb electromagnetic energy at a wavelength 1 and to efficiently emit the absorbed energy at a wavelength 2, wherein quantum energy of the wavelength 2 is higher than quantum energy of the wavelength 1 (FIG. 5) that leads to cooling the up-conversion medium and subsequently to cooling the electronic component.

The changing or moving of the charge in the electronic component can be within the same type of the charge or within a plurality of charges. For example, in the electronic component 101 such as a capacitor, the capacitor can be charged or discharged with a single electron or many electrons, or if the electronic component 101 is a quantum well, the quantum well can be charged or discharged by separation or recombination of a positive charge (hole) and a negative charge (electron).

One of the embodiments of the inventions includes the use of a non up-conversion material 105 (FIG. 1) embedded into the up-conversion medium to enhance up-conversion or cooling capabilities of the up-conversion medium. For example of the non up-conversion material 105 can be a metal nanoparticle, which will enhance up-conversion capabilities of the up-conversion medium by increased absorption of energy at the wavelength 1 emitted by the electronic component.

In the design, the intensity of cooling electronic component is proportional to a frequency rate of changing the charge in the electronic component. Therefore, the proposed invention answers current existing cooling problems in high frequency processing rate, high power and density electronic devices.

The design also includes an external up-conversion cooling of the IC chips by an electromagnetic source 104 that irradiates the up-conversion medium 102 at the wavelength 1 (FIG. 3) that leads to cooling the up-conversion medium 102 and subsequently to cooling the electronic component 101. The electromagnetic source 104 may also be placed inside of the electronic component as is shown on FIG. 4, and the source 104 can irradiate the medium embedded into the electromagnetic source 104 leading to the internal cooling of the electronic component 101.

While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
