1Temperature
If conventional cooling liquids are used for heat dissipation, then cooling effect is achieved, but viscosity and acid value increase over time due to material aging, leading to system failures
Solution Approach 1:
The patent applies preliminary action by incorporating antioxidants and metal deactivators into the cooling liquid formulation before use. These additives pre-protect the dielectric compound from oxidation and metal-catalyzed degradation, preventing viscosity increase and acid value rise before they can occur during operation, thereby maintaining system reliability over time.
Solution Approach 2:
The patent uses antioxidants and metal deactivators as intermediary substances that mediate between the dielectric compound and harmful environmental factors (oxygen, metal ions). These intermediaries sacrificially react with or neutralize the harmful agents, protecting the main cooling liquid components from degradation and preventing system failures.
2Duration of action of moving object
If cooling liquid operates over extended periods, then heat dissipation continues, but material aging causes increased viscosity and acid value, reducing efficiency
Solution Approach 1:
The cooling liquid is pre-formulated with antioxidants and metal deactivators that activate immediately upon contact with oxygen or metal surfaces. This preliminary protective action ensures that even during extended operational periods, the dielectric compound resists degradation, maintaining low viscosity and acceptable acid values throughout the service life, thus preserving heat dissipation efficiency.
Solution Approach 2:
The patent modifies the chemical parameters of the cooling liquid by selecting specific antioxidants and metal deactivators that change the oxidation resistance and stability parameters of the system. These parameter changes ensure that viscosity and acid value remain within acceptable ranges over extended operational durations, preventing efficiency loss.
3Ease of operation
If dielectric compound is exposed to oxygen and metal surfaces, then cooling function is performed, but oxidation and catalysis accelerate material aging
Solution Approach 1:
The patent introduces antioxidants as intermediaries that stand between the dielectric compound and oxygen, and metal deactivators that mediate between the compound and metal surfaces. These intermediaries preferentially react with or bind to the harmful agents, forming protective barriers that allow the cooling function to proceed while preventing oxidation and metal-catalyzed degradation of the main compound.
Solution Approach 2:
The patent converts the potentially harmful interactions between the dielectric compound, oxygen, and metal surfaces into beneficial protective mechanisms. The antioxidants and metal deactivators are designed to react with these harmful elements, transforming them from degradation sources into protective agents that stabilize the cooling liquid and extend its service life.
