Description

technical field [0001] Embodiments of the present invention relate to the technical field of heat dissipation devices, and in particular to an embedded micropump-driven heat dissipation structure and heat dissipation method. Background technique [0002] Heat dissipation devices are generally used to dissipate heat from electrical components and equipment, and the heat dissipation methods include conduction heat dissipation, convection heat dissipation, and the like. Conduction heat dissipation refers to a heat dissipation method in which the heat of the body is directly transferred to a lower temperature object in contact with it; convection heat dissipation refers to a heat dissipation method in which heat is exchanged through gas flow. [0003] Existing components and chips will emit a lot of heat during use. At the same time, existing chips are becoming more and more integrated. Therefore, in the actual use of existing chips, under a small area, A large amount of heat i...
