Abstract
The present invention provides a heat-radiating module with composite phase-change heat-radiating efficiency. The cooling pad of the heat-radiating module is fitted with a heating portion and radiating portion. The first and second chambers are placed at intervals into the cooling pad. The first and second phase-change materials are separately placed in two chambers. The reaction temperatures of two phase-change materials differ from each other. The phase-change material of higher reaction temperature assists in heat-absorbing and preventing overheating. There is a heat peak when the cooling pad reaches the preset high-temperature state. When the temperature of the cooling pad declines below a preset temperature, the phase-change material of lower reaction temperature will release the stored latent heat, enabling the cooling pad to maintain an operating temperature and improve the heat-radiating efficiency in a variety of equipment.
