Abstract: A phase change evaporator includes multiple heat-dissipating fins formed on an evaporator body of the evaporator. A cooling device includes the evaporator, a condenser, a coolant output pipe and a coolant return pipe connected between the evaporator and the condenser, and coolant filled inside a closed coolant circulation loop formed by the evaporator, the condenser, the coolant output pipe and the coolant return pipe. When the evaporator body absorbs heat, the coolant inside the evaporator body is converted into a gaseous state by the heat and then quickly dissipates the heat absorbed thereby through the heat-dissipating fins for a part of the gaseous coolant to be condensed to resume heat absorption and for the remaining part to flow to the condenser through the coolant output pipe to be condensed to a liquid state and return to the evaporator body along the coolant return pipe for heat absorption.

Abstract: A heat dissipating apparatus has a phase change material evaporator, a condenser, a refrigerant output tube, and a refrigerant input tube. The evaporator has a base having an evaporation chamber, a refrigerant inlet and a refrigerant outlet, a reinforcement panel mounted in the evaporation chamber and dividing the evaporation chamber into two spaces, and multiple heat conduction fins separately arranged in the two spaces. An opening area of the refrigerant outlet is larger than an opening area of the refrigerant inlet. The evaporator, the refrigerant output tube, the condenser and the refrigerant input tube form a closed refrigerant circulation loop with a refrigerant filled therein. Gas pressure of a gas-phased refrigerant in the two spaces can be increased. With pressure difference between the refrigerant outlet and the refrigerant inlet, the gas-phased refrigerant can be accelerated to flow toward the refrigerant outlet and flowability of the refrigerant can be increased.

Abstract: A cooling device includes a parallel-connected condenser and an evaporator assembly. The parallel-connected condenser has a primary condenser assembly and at least one auxiliary condenser assembly. The evaporator assembly includes an evaporator, a coolant input pipe and a coolant output pipe. Two ends of the coolant input pipe are respectively connected to the evaporator and a first primary condenser tube. Two ends of the coolant output pipe are respectively connected to the evaporator and a second primary condenser tube for the parallel-connected condenser and the evaporator assembly to form a closed coolant circulation loop with coolant filled therein. By virtue of the primary condenser assembly and the auxiliary condenser assembly parallelly connected, gaseous coolant can be circulated through different paths and liquefied to effectively enhance cooling and liquefaction efficiency of coolant when the coolant is circulated through the cooling device.

Abstract: A refrigerant heat dissipation apparatus has an evaporator, a condenser having a first condensing tube and a second condensing tube, a first refrigerant tube, two second refrigerant tubes, and a refrigerant. The first refrigerant tube is connected between the top of the evaporator and an upper part of a first condensing tube. The second refrigerant tubes are respectively connected with a lower part of the first condensing tube and a lower part of the second condensing tube, so as to form a multi-flow closed-loop cycle. The refrigerant is filled into the multi-flow closed-loop cycle. The controlling of cycling direction of the refrigerant achieves the efficiency in heat dissipating of the refrigerant heat dissipation apparatus.

Abstract: A liquid-cooling heat sink has a heat-conductive tube and multiple heat-conductive units arranged adjacent to the heat-conductive tube. The heat-conductive tube has a first tube and a second tube. An isolation member having an isolation channel is located between the first tube and the second tube. The isolation member obstructs the heat exchange between the first tube and the second tube. A first delivery tube and a second delivery tube of each one of the heat-conductive bodies respectively connect to the first tube and the second tube of the heat-conductive tube, thereby integrating the first tube and the second tube and obstructing the heat exchange between the cooling liquids with different temperatures. Each of the heat-conductive units distributes the cooling liquids with different temperatures by the heat-conductive tube, thereby simplifying the pipeline setting and reducing the volume of the liquid-cooling heat sink.
