A method of tracking an engine cooler in an aircraft includes recording an orientation of the engine cooler as orientation N. Prognostic health management data of the aircraft is tracked. A maintenance check of the aircraft is performed based on the tracked prognostic health management data. Whether to rotate an orientation of the engine cooler is determined with an aircraft maintenance database based on the tracked prognostic health management data of the aircraft. A recommendation is provided by the aircraft maintenance database as to whether to rotate the engine cooler. The orientation of the engine cooler is recorded as orientation N+1.

A heat dissipation device has a frame assembly, a gravity loop thermosyphon, and a dissipating fin assembly. The gravity loop thermosyphon has a heat exchanger, a condenser, two bendable tubes, and working fluid. One end of each bendable tube communicates with the heat exchanger and another end of each bendable tube communicates with the condenser and thus the working fluid may circulate therein. After the bendable tubes are bent, the condenser can be moved to an appropriate location or tilted to an appropriate angle according to the environment, and then the location and the angle are fixed via the frame assembly so the gravity loop thermosyphon can adapt for different dissipation assemblies.

A heat storage and transfer system that incorporates a primary heat storage chamber or body that is thermally insulated and which in use contains a heat storing liquid or solid; and a secondary chamber external to and adjacent the primary heat storage chamber or body through which a liquid, heat transfer fluid or steam to be heated is passed in use, the system having a heat transfer mechanism to selectively transfer thermal energy from the heat storing liquid or solid of the primary heating chamber or body to the liquid or steam to be heated in the secondary chamber. The heat transfer mechanism has a drive that moves the secondary chamber from a first position that is thermally separated from the primary chamber into a second position that is substantially inserted in a void or recess within the primary chamber or body.

An electronic device includes a loop type heat pipe including a loop-shaped flow path in which a working fluid is enclosed, a first magnet provided to the loop type heat pipe, a heat dissipation plate thermally connectable to the loop type heat pipe, a second magnet provided to the heat dissipation plate and provided to face the first magnet, and a support member that supports the heat dissipation plate movably between a position in which the heat dissipation plate is thermally connected to the loop type heat pipe and a position in which the heat dissipation plate is not thermally connected to the loop type heat pipe.

The present invention relates to improved subsea or submerged cooler designs for subsea applications, and particularly to a unique pipe support arrangement (5, 16, 17, 18) in a submerged cooler (20), an improved submerged cooler frame (1) and an improved submerged cooler (20).

A frame-mounted mobile cleaning system permanently positionable above or below the tube bundles of an air-cooled heat exchanger (ACHE) and in fluid communication with an external source of pressurized cleaning fluid includes a mobile transverse spray head assembly formed from a plurality of separate interchangeable fluid compartments, each fluid compartment having an inlet for receiving the pressurized cleaning fluid and a fluid discharge wall having at least one nozzle aligned with the longitudinal axes of the finned heat exchange tubes below or above, or elongated slot nozzles that are transverse to the axes of the finned tubes and that are configured to discharge a predetermined pattern of pressurized cleaning fluid onto and between the surfaces of the fins of the heat exchange tubes as the assembly is moved from one end of the ACHE tube bundles to the other.

A high-efficiency electronic thermal management system and method providing a heat riser having stackable blocks of thermally conductive material that include an upper block and a lower block, wherein the lower block has a lower surface mounted in thermal communication with a heat source. The lower block having an inclined upper surface configured to be in thermal communication with a block directly above, having a complemental inclined surface. These blocks are elastically coupled. The upper block may slide along the lower block allowing for vertical and horizontal axial elastic adjustment while providing consistent pressure to both the heat source and a cooling source to provide for heat dispersion along a thermal pathway from the heating source through the lower block, upper block, and to a cold plate cooling source. The cold plate also has internal fins and flowing liquid for heat dispersion.

According to the present disclosure, a laptop may be provided with a compartment including a moveable segment, an expandable heat exchanger with a movable section, and an expandable fan unit. The release of the movable segment of the compartment from a lower portion of the compartment produces an opening in the compartment and the movable section of the expandable heat exchanger is extended downward, and the expandable fan unit is lowered when the movable segment of the compartment is released.

In one aspect, an apparatus comprises a housing, a heat-generating component, a heat spreader, and a heat-transfer pipe. The housing forms a cavity in which the heat-generating component is located. The heat spreader is operable to distribute heat over a portion of the housing. The heat-transfer pipe is pivotally coupled to the heat-generating component and the heat spreader. The heat-transfer pipe operable to transfer heat from the heat-generating component to the heat spreader. The heat-transfer pipe and the heat spreader are movable between a first configuration and a second configuration. In the first configuration, a gap separates the heat spreader and the portion of the housing based on the heat-transfer pipe being at a first orientation. In the second configuration, the heat spreader closes the gap and is thermally coupled to the portion of the housing based on the heat-transfer pipe being at a second orientation.

A pump cooling system may include a cooling body configured to be fitted to a pump housing to receive heat from the pump housing via a heat conducting path between the cooling body and pump housing. The cooling body may have a passage through which, in use, a cooling fluid is passed to conduct heat away from the cooling body. The pump cooling system includes a cooling control mechanism configured to provide a gap in the heat conducting path at pump operating temperatures below a predefined temperature so heat conduction from the pump housing to the cooling body is interrupted.
