Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrolysis devices face challenges in efficiently cooling the process water in high ambient temperatures, leading to overheating and increased costs due to complex and energy-intensive cooling methods, and risk of frost damage at low temperatures without antifreeze.
Innovation Solution
The electrolysis device employs a cooling device positioned at an angle to directly release heat from the process water to the environment, with a control unit that empties the cooling device into a liquid storage when temperatures drop below 1°C, using a height difference or pressurized gas to prevent freezing and maintain system pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If compression cooling is used to cool the electrolysis system in high ambient temperatures, then the cooling capacity is improved, but the energy consumption and acquisition costs increase significantly
Solution Approach 1:
The invention extracts the heat directly from the process water circuit and dissipates it to the environment through heat exchangers, eliminating the need for complex compression cooling systems. This removes the energy-intensive refrigeration cycle while maintaining effective cooling capability.
Solution Approach 2:
The heat exchangers serve dual functions: they cool the process water during operation and can be integrated with the product gas drying system, allowing the same thermal management infrastructure to handle multiple process requirements without additional energy consumption.
2Temperature
If water is injected onto the coolers to create additional cooling effect, then the cooling capacity is improved, but water losses increase and profitability decreases
Solution Approach 1:
The invention converts the waste heat that would otherwise be a harmful thermal load into a useful resource by integrating it with the product gas drying process. The heat exchangers use this thermal energy to condense and dry the product gases, turning a cooling requirement into a dual-purpose thermal management system that eliminates water injection and associated losses.
3Temperature
If large heat exchange surfaces are used to dissipate heat in high ambient temperatures, then the cooling capacity is improved, but the device complexity and costs increase
Solution Approach 1:
The invention merges the process water cooling function with the product gas drying function into a single integrated thermal management system. The heat exchangers perform both cooling of electrolysis water and drying of product gases simultaneously, reducing the total heat exchange surface area required compared to separate systems.
4Temperature
If the cooling device operates continuously to maintain cooling capacity, then the temperature control is improved, but energy consumption increases during standby mode
Solution Approach 1:
The invention implements dynamic control of the cooling system by coupling it with the electrolysis operation status. The heat exchangers are activated only when electrolysis is running and cooling is required, and are automatically deactivated during standby or shutdown modes. This dynamic operation maintains temperature control when needed while eliminating unnecessary energy consumption during idle periods.
