Solution Overview
Problem
High-performance computer systems, particularly in Bitcoin mining and AI computing, face inefficiencies in rejecting thermal energy, leading to wasted energy that cannot be efficiently repurposed for commercial processes.
Innovation Solution
The system utilizes the otherwise wasted thermal energy by compressing the vapor phase of the working fluid, increasing its temperature and pressure, and then using it to drive commercial processes through a heat exchanger, thereby reducing energy costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If thermal energy is rejected directly to the surrounding environment, then the cooling system operates simply, but the thermal energy is wasted and cannot be efficiently repurposed
Solution Approach 1:
The patent converts the previously wasted thermal energy into a useful resource by integrating a vapor compression system. The thermal energy from the computer system heats the working fluid vapor, and through compression, this heat is transformed into high-temperature thermal energy that can drive commercial processes, thus converting harm (waste heat) into benefit (useful thermal energy for heating water or other applications).
Solution Approach 2:
The cooling system is enhanced to serve multiple functions: it not only cools the computer system by removing thermal energy but also produces high-temperature thermal energy that can be used to drive commercial processes such as heating water. This multi-functionality allows the same system to both cool the computer and provide useful thermal energy, reducing overall energy waste.
2Use of energy by moving object
If a heat engine is used to extract thermal energy for mechanical work, then some thermal energy can be converted to work, but the efficiency is limited to maximum 12% due to the low temperature of waste thermal energy
Solution Approach 1:
The patent changes the temperature parameter of the thermal energy by compressing the working fluid vapor. The compression process increases the temperature of the vapor from the low temperature of waste thermal energy (40°C to 80°C) to a much higher temperature, making it suitable for driving commercial processes. This parameter change bypasses the efficiency limitations of heat engines at low temperatures.
Solution Approach 2:
The patent replaces the heat engine mechanism with a vapor compression system. Instead of using a heat engine to convert thermal energy to mechanical work (which is inefficient at low temperatures), the system uses compression to directly increase the temperature and pressure of the working fluid, creating high-temperature thermal energy that can be used for heating applications without the efficiency limitations of heat engines.
3Loss of energy
If pumps and cooling fans are used to remove thermal energy, then the thermal energy can be rejected, but additional energy is consumed to drive these components
Solution Approach 1:
The patent merges the thermal energy removal function with a useful thermal energy production function. The same working fluid that absorbs thermal energy from the computer system is then compressed to produce high-temperature thermal energy. This combines the necessary cooling function with a useful heating function, reducing the net energy waste and potentially offsetting the energy consumed by pumps and fans through the useful thermal energy produced.

AI summary
The inventive subject matter provides for repurposing otherwise wasted thermal energy to drive a commercial process. Thermal energy from a cooling system containing a computer system and at least one manifold that is operably coupled with a compressor, heat exchanger, pressure regulator, and controller, to provide thermal energy at an elevated temperature to drive the commercial process. The cooling system can advantageously be used to cool computer systems, including Bitcoin miners, crypto miners, high-performance computers, AI computers, or other thermal energy producing devices. The system operates by extracting vapor of the working fluid from the manifold, increasing the pressure and temperature of the extracted vapor by compression, and then passing this vapor to a heat exchanger, thereby providing thermal energy to drive the commercial process.
