A heat exchange system includes a tubular fan air inlet portion and a tubular cooled air outlet portion connected to a first end of a tubular mid portion. The heat exchange system further includes a tubular hot air inlet portion and a tubular recycled fan air outlet portion connected a second end of the mid portion. Still further, the heat exchange system includes an integrally-formed, compliant heat exchanger tube extending between the hot air inlet portion and the cooled air outlet portion within the mid portion to define a heat exchanger first flow passage within the heat exchanger tube and a second flow passage outside of the heat exchanger tube but within the tubular mid portion. Methods for fabricating such heat exchange systems are also provided.

A thermal energy transfer device attached to an object to dissipate thermal energy from the object is described. In one aspect, the device includes a non-metal base plate and first and second non-metal plate structures. The base plate includes at least one groove on one of its primary surfaces. An edge of the first plate structure is received in a first groove of the at least one groove of the base plate. An edge of the second plate structure is received in a second groove of the at least one groove of the base plate. At least the first groove or the second groove is a V-notch groove such that the edge of the first plate structure or the edge of the second plate structure that is received in the first groove or the second groove is interlockingly received in the V-notch groove.

Disclosed are a flat heat pipe which has a structure integrated with a heat sink, and a facilitated fabrication method thereof. The flat heat pipe includes: a flat body portion including a plurality of heat sink fins formed on an outer surface thereof, and a plurality of through-holes formed therein and being separated by at least one separation film; and at least one groove formed in at least one surface from among a top surface and a bottom surface of one side portion of each of the plurality of through-holes.
摘要:
An insert is configured to be inserted into a heat exchanger having a plurality of tubes. The insert includes a base and a multiple blades. The blades are extended from the base. At least one of the blades has a spring portion. The spring portion is resiliently deformable and configured to be resiliently inserted between two of the tubes.
摘要:
A heat dissipation module includes a heat sink. A plurality of grooves are defined in a bottom surface of the heat sink, a heat pipe is accommodated in each groove of the heat sink, and a heat conducting pad made of phase change material is adhered to the bottom surface of the heat sink to cover the grooves and the heat pipes. The heat conducting pad is a solid material at an ambient room temperature. When heated to a temperature higher than a transition temperature of the heat conducting pad, the heat conducting pad softens to fill spaces between the heat conducting pad, the heat sink, and the heat pipes.
摘要:
A heat exchanger, turbulizer or heat transfer surface, and a method of making same wherein the turbulizer is a corrugated member having parallel, spaced-apart ridges and planar fins extending therebetween. The planar fins have spaced-apart apertures with opposed peripheral edge portions including transversely extending flanges.

Some modular heat-transfer systems can have an array of at least one heat-transfer element being configured to transfer heat to a working fluid from an operable element. A manifold module can have a distribution manifold and a collection manifold. A decoupleable inlet coupler can be configured to fluidicly couple the distribution manifold to a respective heat-transfer element. A decoupleable outlet coupler can be configured to fluidicly couple the respective heat-transfer element to the collection manifold. An environmental coupler can be configured to receive the working fluid from the collection manifold, to transfer heat to an environmental fluid from the working fluid or to transfer heat from an environmental fluid to the working fluid, and to discharge the working fluid to the distribution manifold.
