Abstract

Methods, apparatuses, systems, computing devices, and/or the like are provided. An example system for heat dissipation may include a memory. The example system may also include a processor configured to receive at least one visual representation of at least a portion of the sky, determine, based on the at least one visual representation (e.g., using artificial intelligence), a mask distinguishing between clouded and cloudless portions of the sky, based on the mask, determine a direction in which to point a heat dissipation panel toward one or more aim portions of the sky, and generate a signal to cause one or more heat dissipation surfaces or panels to be moved (e.g., using a robotic arm) such that heat is radiated toward the one or more aim portions of the sky.

Claims (44)

1 . A system for heat dissipation comprising:

a memory; and

a processor configured to:

receive one or more images of at least a portion of the sky;

determine, based at least in part on the one or more images of at least a portion of the sky, one or more aim portions of the sky comprising three-dimensional coordinates;

employ artificial intelligence to determine:

one or more portions in the one or more images of the at least a portion of the sky where the sky is cloudless or thinly clouded; and

one or more portions in the one or more images of the at least a portion of the sky that require a minimum of movement from one or more heat dissipation surfaces different from the one or more portions where the sky is cloudless or thinly clouded;

determine the one or more aim portions of the sky that correspond to the one or more portions in the one or more images that require a minimum of movement from the one or more heat dissipation surfaces; and

controlling the one or more heat dissipation surfaces to be moved in three-dimensional space based on the determination, such that heat is radiated toward the one or more aim portions of the sky.

2 . The system of claim 1 , wherein the system for heat dissipation further comprises a camera, wherein the camera is configured to capture one or more images of the sky, the one or more images of the sky being received by the processor.

3 . The system of claim 1 , wherein a robotic arm is configured to tilt and turn the one or more heat dissipation surfaces.

4 . The system of claim 1 , wherein the processor is further configured to determine whether to perform radiative cooling using the one or more heat dissipation surfaces, to perform active liquid cooling using a cooling tower, or to perform a combination of radiative cooling and active liquid cooling using the one or more heat dissipation surfaces and the cooling tower, respectively.

5 . The system of claim 1 , wherein the one or more heat dissipation surfaces comprise one or more passive cooling panels configured to emit electromagnetic energy and to cool liquid flowing through the one or more passive cooling panels.

6 . The system of claim 1 , wherein the one or more heat dissipation surfaces are configured to cool liquid that is circulated through a heat-producing component to cool the heat-producing component.

7 . A method for heat dissipation comprising:

receiving, at a computer processor, one or more images of at least a portion of the sky;

determining, by the computer processor, if there exists one or more aim portions of the sky, based in part on the one or more images of at least a portion of the sky comprising three-dimensional coordinates;

using artificial intelligence to determine:

one or more portions in the one or more images of the at least a portion of the sky where the sky is cloudless or thinly clouded; and

one or more portions in the one or more images of the at least a portion of the sky that require a minimum of movement from one or more heat dissipation surfaces different from the one or more portions where the sky is cloudless or thinly clouded;

determining the one or more aim portions of the sky that correspond to the one or more portions in the one or more images that require a minimum of movement from the one or more heat dissipation surfaces; and

based on the one or more aim portions of the sky, controlling, by the computer processor, the one or more heat dissipation surfaces to be moved in three-dimensional space based on the determination, such that heat is radiated toward the one or more aim portions of the sky.

8 . The method of claim 7 , wherein a robotic arm is configured to tilt and turn the one or more heat dissipation surfaces.

9 . The method of claim 7 , the method further comprising determining whether to perform radiative cooling using the one or more heat dissipation surfaces, to perform active liquid cooling using a cooling tower, or to perform a combination of radiative cooling and active liquid cooling using the one or more heat dissipation surfaces and the cooling tower, respectively.

11 . The method of claim 7 , wherein the one or more heat dissipation surfaces are configured to cool liquid that is circulating through a heat-producing component to cool the heat-producing component.

12 . A system for heat dissipation comprising:

a memory; and

a processor configured to:

receive at least one visual representation of at least a portion of sky;

determine, based on the at least one visual representation of the at least a portion of sky, a mask distinguishing between clouded and cloudless portions of the sky;

employ artificial intelligence to determine:

one or more portions in the determined mask of the visual representation where the sky is cloudless or thinly clouded; and

one or more portions in the mask of the visual representation that require a minimum of movement from one or more heat dissipation surfaces different from the one or more portions where the sky is cloudless or thinly clouded;

determine the one or more aim portions of the sky that correspond to the one or more portions in the mask of the visual representation that require a minimum of movement from the one or more heat dissipation surfaces;

and

controlling the one or more heat dissipation panels to move in three-dimensional space based on the determination to point toward the one or more aim portions of the sky, if there exists the one or more aim portions of the sky.
