A ladder-structural gravity-assisted-heat-pipe geothermal energy recovery system without liquid-accumulation effect, comprises a ladder-structural gravity-assisted heat pipe, a condenser, and a liquid tank. The ladder-structural gravity-assisted heat pipe comprises a return pipe, an outer pipe and an inner pipe. The return pipe is provided in a space between the outer pipe and the inner pipe and communicated with the liquid tank, and the space between the outer pipe and the inner pipe is divided to form a ladder structure. A liquid working medium flows from the liquid tank through the return pipe into each section sequentially, absorbs heat from a high-temperature rock through a wall of the outer pipe, vaporizes into a gaseous working medium, gets into the inner pipe, and rises to the condenser to condense and flows to the liquid tank to circulate. Such design greatly improves the heat transfer efficiency in geothermal energy recovery using ultra-long heat pipes.

A battery-mounted vehicle according to an example of the present disclosure accommodates one or a plurality of batteries under the floor panel. The battery-mounted vehicle includes a battery-cooler unit, a condenser, a refrigerant liquid pipe, and a plurality of refrigerant gas pipes. The refrigerant liquid pipe guides the refrigerant liquid from the condenser to the battery-cooler unit. The refrigerant gas pipe guides the refrigerant gas generated by vaporization of the refrigerant liquid from the battery-cooler unit to the condenser. The plurality of refrigerant gas pipes include a first and a second refrigerant gas pipes. The first refrigerant gas pipe extends in a first direction from the battery-cooler unit to the condenser, and connects the condenser and the battery-cooler unit. The second refrigerant gas pipe extends from the battery-cooler unit in a second direction opposite to the first direction, and is connected to the condenser by being bended or curved.

A heat conductor includes a housing including a space therein, a working medium in the space, and a wick in the space. The housing includes a first region, a second region located at one side of the first region in one direction perpendicular to a thickness direction of the housing, and a third region located at another side of the first region in the one direction. The first region includes a first end portion connected to the second region, and a second end portion connected to the third region. The wick is only in the second region.

An electric ice press includes a mold body having a first mold segment and a second mold segment movable relative to each other. A heated guide rail extends between the first mold segment and the second mold segment to transfer heat from the first mold segment to the second mold segment. The heated guide rail may be a heat pipe for transferring heat generated by a base heater in the first mold segment or an electrical resistance heating rod for generating heat, either of which requires only a single power cord electrically coupled to only the first mold segment.

A gas-liquid separator includes a chamber having an inlet for liquid to enter and at least one outlet for expulsion gas and/or vapour that has separated from the liquid within the chamber under gravity. For some applications the chamber will also have an outlet for the liquid. These systems can rely on the chamber remaining in a static orientation with the gas outlet arranged uppermost. Exemplary embodiments provide the chamber with multiple spaced apart outlets and an ability to sense orientation and/or acceleration of the chamber. A controller uses the output of the sensors to determine the spatial arrangement of the liquid phase and gas phase within the chamber relative to the outlets and selectively opens the multiple outlets to allow one of the liquid phase or gas phase to escape the chamber in preference to the other.
