A water extractor includes an inlet, an outlet a body, outer wall, inner wall, helical wall, plurality of catchment areas, and scuppers. The body extends between the inlet and the outlet. The inner wall is disposed radially inward from the outer wall and forms a main flow channel through a portion of the body. The helical wall extends between and is connected to the outer wall and the inner wall and forms a helical passageway fluidly connected to the inlet and the outlet. The helical passageway includes a plurality of turns along a bottom of the body. One of the catchment areas is disposed in each turn of the helical passageway. The scuppers are disposed in the catchment areas and are connected to and extend radially inward from the outer wall.

A shroud for a J-tube of an air conditioning pack of an aircraft includes a first partial shroud piece and a second partial shroud piece that mate together to form a flow tube and a sleeve. The flow tube includes an inlet, an outlet fluidly connected to the inlet and disposed on an opposite end of the flow tube from the inlet, and a sidewall extending between the inlet and the outlet. The sleeve extends through a portion of the flow tube and out of the sidewall and is configured to contain a portion of the J-tube.

An approach is provided in which a manufacturing test scheduling system predicts a dew point forecast indoor a facility based upon outdoor weather data and indoor environment data. The manufacturing test scheduling system selects time slots in the dew point forecast based upon a pre-defined dew point threshold and, in turn, schedules tests of a liquid cooled computer system during the selected time slots.

A refrigerant flow path switch arranged between an outdoor device and each of multiple indoor devices controls a refrigerant flow and is provided with a housing; a refrigerant flow path switching circuit having multiple refrigerant flow path switching circuits, wherein each refrigerant flow path switching circuit includes a high/low pressure gas pipe, a low pressure gas pipe, a high/low pressure electric valve provided at the high/low pressure gas pipe, and a low pressure electric valve provided at the low pressure gas pipe. A liquid pipe assembly is arranged in the housing and has multiple liquid pipes connected to the multiple indoor devices. A first divider plate is provided between adjacent ones of the refrigerant flow path switching circuits and divides an internal space of the housing such that a space divided by the first divider plate is in a substantially cubic shape, which is filled with a foaming agent.

According to one embodiment, a heat transport apparatus includes an evaporator, a cooling unit, a channel structure, and a heating mechanism. The evaporator vaporizes a refrigerant by heat generated by a heat-generating element. The cooling unit is provided above the evaporator and cools and condenses the refrigerant vaporized in the evaporator. The channel structure constitutes a channel through which the refrigerant circulates between the evaporator and the cooling unit. The heating mechanism heats the cooling unit and suppresses solidification of the refrigerant at the cooling unit.

An evaporator includes: an evaporator case that defines a food storage space therein; a cooling tube located at the evaporator case and filled with refrigerant; a foil heater attached to at least one surface of the evaporator case and configured to contact the evaporator case and to generate heat such that heat for defrosting is transferred to the evaporator case. A defrosting time is reduced in comparison to that of conventional natural defrosting, such that the freshness of food can be maintained, and the cooling efficiency, having been reduced by frost, is increased such that power consumption can be reduced. The foil heater is attached to a conventional roll-bond type evaporator case, and the present invention has an advantageous effect of facilitating the maintenance of the foil heater because of a structure in which the foil heater is attached to the evaporator case.
