Abstract: The present invention provides a stack-type vertical heat dissipation device comprising an evaporator unit and a condenser unit. The evaporator unit has a side configured for direct or indirect contact with, and thereby receiving heat from, a high-temperature device in order for the heat to convert a heat conduction medium inside the evaporator unit into a gaseous state. The condenser unit is stacked on a top side of a housing of the evaporator unit, and is provided therein with a flow channel that is in communication with the evaporator unit and allows passage of the heat conduction medium so that the heat conduction medium is able to return to the evaporator unit under a force of gravity after condensing from the gaseous state into a liquid state and thereby complete a thermal cycle.

Abstract: The present invention provides a gravity high-efficiency heat dissipation apparatus comprising an evaporator and a condenser. The evaporator comprises a housing, an evaporation chamber arranged at the housing, and a skived structure arranged inside the evaporation chamber. The condenser comprises an upper circulating main pipe, a lower circulating main pipe and one or a plurality of condensation pipes having an upper opening and a lower opening fluidly connected to the upper circulating main pipe and the lower circulating main pipe respectively. The upper circulating main pipe is fluidly connected to an upper side of the evaporator via a first connecting pipe and is fluidly connected to an upper side of the evaporation chamber. The lower circulating main pipe is fluidly connected to one side of the evaporator via a second connecting pipe and is fluidly connected to the evaporation chamber. A circumferential side of each of the condensation pipes has one or a plurality of heat dissipation fins formed thereon.
