Problems solved by technology

[0007] Existing methods must use mechanical stirring and disturbance to mix refrigerants, or add surfactants to form microemulsions, and it is difficult for nanoparticles to be uniformly distributed in a two-phase system, and must be continuously applied even when additives are added. External stirring or circulation promotes the mixing of the two phases. The presence or absence and continuity of this external force greatly affects the mixing degree of the two phases, thus affecting the heat transfer performance of the refrigerant product.
In addition, the external mechanical shear force, electromagnetic field and ultrasonic wave have greatly increased equipment investment and energy consumption, and the operation is cumbersome.
