A system for power generation from renewable energy, comprising a heat exchanger within a subterranean formation. The heat exchanger comprises a casing at an upper portion of the wellbore, a tubular member extending through the casing to a lower portion of the wellbore, and fins in fluid communication with the casing and with the tubular member, the fins each comprising a volume defined by surfaces of the subterranean formation and configured to receive a fluid from the casing. Related longitudinal finned heat exchangers and methods of storing thermal energy within a subterranean formation are also disclosed.

An immersion cooling tank includes a tank body and a liquid flow tube. The tank body holds a coolant and an electronic device. The tank body defines an inlet and an outlet. The inlet and the outlet are respectively located at opposite ends of the electronic device for inputting and outputting the coolant. The coolant flows through the electronic device. The liquid flow tube includes at least one adjuster. The liquid flow tube is located inside the tank body and coupled to at least one of the inlet or the outlet. The at least one adjuster faces the electronic device for controlling an amount of the coolant flowing in or out of the tank body.

The present invention discloses a high-temperature fluid transporting pipeline integrating a heat exchange apparatus, wherein heat contained in a high-temperature fluid can be recovered during the transportation thereof. The heat exchange apparatus comprises a hermetic heat exchange cavity, and a heat-receiving fluid coil installed therein. The method of heat exchange is that the high-temperature fluid heats an auxiliary fluid in the cavity via a heat exchange base plate of the heat exchange cavity in contact therewith, and the heated auxiliary fluid then conducts the heat to a heat-receiving fluid in the heat-receiving fluid coil. As an example, the high-temperature fluid is flue gas generated by combustion, an upper part of a flue gas transporting pipeline is replaced by the heat exchange apparatus of the present invention, the auxiliary fluid is an inert gas such as air, and the air heated indirectly by the high-temperature flue gas conducts heat to fuel and/or oxygen-enriched gas flowing in the heat-receiving fluid coil (as an oxidant/combustion aid).

A heat sink for use in an immersion cooling system that includes a sintered powder structure enclosed in a porous enclosure. The porous enclosure has openings, e.g., formed by a mesh, with a size to help contain sintered powder particles that may be dislodged during operation of the heat sink.

A two-phase immersion heat dissipation structure is provided. The two-phase immersion heat dissipation structure includes an immersion-type heat dissipation substrate, a fin assembly, and a metal reinforcement frame. The immersion-type heat dissipation substrate has an upper surface having the fin assembly arranged vertically thereon and a lower surface used for contacting a heat generating element. The metal reinforcement frame is surroundingly in contact with a peripheral wall of the immersion-type heat dissipation substrate, and the metal reinforcement frame has two reinforcement side walls correspondingly protruding from a surface thereof. The two reinforcement side walls are arranged opposite to each other, and a height of the reinforcement side wall is between 5 mm and 15 mm. Each of the two reinforcement side walls has a plurality of through holes that horizontally pass through the reinforcement side wall and that are used for a replenishment of a two-phase coolant.
