  • Publication number: 20210033356
    Abstract: A heat dissipating apparatus used in non-forced convection includes a cooling plate assembly, an upper shielding plate, a lower shielding plate, a metal base, and heat pipes. The cooling plate assembly has a cutting opening. The upper and the lower shielding plates cover the cutting opening above and below the cooling plate assembly, respectively. The metal base is disposed below the lower shielding plate and has plural cooling fins. Each heat pipe has an evaporator section, a first condenser section, and a second condenser section. Each evaporator section is fixed to the metal base. Each condenser passes through the cooling plate assembly and is closed to two sides of the cutting opening. Therefore, the wind resistance is reduced and the friction between air flow and the cooling plates is decreased, which further enhances the whole performance of heat conduction and dissipation.
