A tank assembly has heat-generating equipment contained therein. The tank assembly includes a tank having an opening, and a thermal siphon fixed to the tank and sealing the opening of the tank. The thermal siphon has a main body portion and a loop portion. The thermal siphon contains a liquid and a gas. A center of the loop portion is exposed to the environment.

An integrated type air conditioning device includes a first refrigeration cycle that is an evaporative cooling type, a second refrigeration cycle that is a vapor-compression type, a blower device, and a housing accommodating the first and second cycles. The first refrigeration cycle includes an evaporation heat exchanger, a condensation heat exchanger, and a first refrigerant pipe. The second refrigeration cycle includes a compressor, a condenser, a decompression device, an evaporator, and a second refrigerant pipe. The housing is partitioned into an interior air passage and an exterior air passage. The evaporation heat exchanger and the evaporator are positioned in the interior air passage, the evaporation heat exchanger being located upstream of the evaporator with respect to an interior airflow in the interior air passage. The blower device is disposed in the interior air passage and is driven to generate the interior airflow in the interior air passage.

An aircraft with a thermal management system and method of operating the thermal management system within an aircraft includes an avionics unit adapted to store at least one heat generating component, a first interface operably coupled to the avionics unit and thermally coupled to the at least one heat generating component; and a plurality of heat pipes, wherein a first end of the plurality of heat pipes is coupled to the first interface, defining a hot interface, and a second end of the heat pipes is coupled to the at least one of the fuselage, the wing, the skin, or the support structure.

A system includes a heat exchanger mounted to the brackets and receiving cryogen, the heat exchanger having a vertical inlet coupled in parallel to a plurality of equal size horizontal tubes each traversing a width of the heat exchanger and further coupled in parallel to a vertical outlet pipe with an outlet diameter at least twice an inlet tube diameter; a temperature sensor; a thermostat that monitors the temperature sensor and maintains a predetermined temperature set point by communicating with a solenoid valve coupled to the heat exchanger; an exhaust line coupled to the outlet pipe that expels exhaust gas outside the enclosed facility; multiple fans attached to the heat exchanger; and a fail-safe oxygen sensor to protect a biological object in the enclosed facility.

An evaporator incorporated into a transportation machine includes: heat exchange units aligned in a horizontal direction in the transportation machine placed on a horizontal surface and whose positions change together; distribution conduits connected respectively to the heat exchange units to supply a working fluid in a liquid phase to the heat exchange units; and valves disposed respectively in the distribution conduits to block passage of the working fluid flowing from the heat exchange units toward the distribution conduits at least when a tilt of the heat exchange units is equal to or greater than a predetermined threshold. Each heat exchange unit includes: an inlet portion connected to the distribution conduit; and a heat exchange portion that includes at least one heat exchange path extending straight upward from the inlet portion and that allows the working fluid passing through the heat exchange path to exchange heat with the heat source.
