A thermosiphon device includes an evaporator section, a condenser section and a liquid path configured to deliver liquid that exits the evaporator section directly back to the evaporator inlet. The condenser section has a significantly reduced mass flow rate and lower pressure drop as compared to the evaporator section, which has an increase liquid fraction of working fluid.

A thermal module includes a base seat and multiple heat pipes. The base seat has a heat absorption side and a heat conduction side. Each heat pipe has a heat absorption end and a heat dissipation end. The heat absorption end has a pair of long sides and a pair of short sides. The long sides and the short sides are connected with each other in the form of a loop to form the heat absorption end. The heat pipes are assembled with each other with the long sides attached to each other.

The double-layer heat exchange tube component includes an upper bellows and a lower bellows.

A heat dissipation net disposed on a base plate of a vapor chamber unit includes a base net portion and conduction units formed on the base net portion. Each conduction unit has a protruding area, a recessed area, and a curved section formed between the protruding area and the recessed area. When the heat dissipation net is disposed on the base plate, the existence of the recessed area and the curved section prevents the base net portion from being unduly pressed and stuck to the base plate to thereby improve a capillary action of the heat dissipation net. A space formed between each protruding area and the base plate facilitates the quick conduction of vaporized working fluid of the vapor chamber unit. Thus, the entire heat dissipation efficiency is increased.

A wind turbine, including a main gear box, which is lubricated and/or cooled by oil, and a thermosiphon cooling system for cooling the oil is provided. The thermosiphon cooling system solves the main challenges facing the oil cooling systems in wind turbines. The high efficiency of the evaporation heat transfer mechanism gives the capacity to transfer the required heat load in relatively smaller size system. In this way, installation space is reduced. The thermosiphon cooling system has no service requirements over the lifetime of the wind turbine since the thermosiphon cooling system has no moving parts. Costs are saved since the simplicity of the thermosiphon cooling system adds a big value to the system business case.
