Abstract: A condenser has a main condensing module, an auxiliary condensing module, and a connecting tube. The main condensing module has an input base tube, a first connecting base tube, and a main heat dissipating mechanism, which are series connected. The auxiliary condensing module has a second connecting base tube, an output base tube, and an auxiliary heat dissipating mechanism, which are series connected. The connecting tube is mounted between the main condensing module and the auxiliary condensing module. An interior room of the first connecting base tube communicates with an interior room of the second connecting base tube.

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.
