Abstract:
Embodiments of heat spreaders with integrated preforms, and related devices and methods, are disclosed herein. In some embodiments, a heat spreader may include: a frame formed of a metal material, wherein the metal material is a zinc alloy or an aluminum alloy; a preform secured in the frame, wherein the preform has a thermal conductivity higher than a thermal conductivity of the metal material; and a recess having at least one sidewall formed by the frame. The metal material may have an equiaxed grain structure. In some embodiments, the equiaxed grain structure may be formed by squeeze-casting or rheocasting the metal material.
Abstract:
Materials that readily adhere to and conform to various surfaces can be desirable for a number of applications. In heat transfer and thermal management applications, for example, conformable materials can be used in establishing a thermal interface between a heat source and a heat sink. There are limited materials that provide good thermal conductivity values while maintaining capabilities to readily adhere and conform to a surface. Compositions including a conformable and adhesive solid can include a reaction product formed by heating a mixture containing a plurality of metal nanoparticles, one or more amines, and one or more carboxylic acids. The compositions can further include one or more additives dispersed in the conformable and adhesive solid.
Abstract:
A system for providing effective and efficient air conditioning using a plurality of hybrid capillary panels installed. The system includes a compressor and a condenser. The compressor has suction and discharge ports and a number of hybrid capillary panel units run between the compressor suction port and the condenser. One or more solenoid valves block and unblock at least one of the panel units. Further the hybrid capillary panel units comprise PCM (phase changing material) packs.
Abstract:
There is provided a thermal interface material, TIM, a thermal interface application comprising such a TIM, and corresponding methods for providing the material and the thermal interface. The TIM comprises a TIM layer in which an activable shrinkage material is distributed, such that upon activation of the shrinkage material the thickness of the TIM layer is increased. In the thermal interface application, where the TIM (400) is arranged between a heat generating component (20) and a heat conducting element (30), the increase in thickness of the TIM layer is utilized to increase the contact pressure on mating surfaces. The TIM is sandwiched between the heat generating component and the heat conducting element before the activation of the shrinkage material, and the distance (h) between the heat generating component and the heat conducting element is restricted such upon activation of the shrinkage material, the restricted maximum height (h) between the heat generating component and the heat conducting element in combination with the TIM increasing the thickness of the TIM layer, the contact pressure on the mating surfaces is increased.
Abstract:
A heat exchanger includes a shell made of a composite material, and a heat exchanger housed substantially within the shell. The shell is made of a composite material further comprises planks positioned in the outer periphery of the shell. The planks, in one embodiment, are substantially hollow or include substantially hollow portions. In some embodiments, the planks are formed of pultruded plastic. The shell of the heat exchanger further includes layers of fiberglass. The pultruded plastic planks are sandwiched between at least a first layer of fiberglass and a second layer of fiberglass. The layers of fiberglass are infused with resin. A floating portion of an Ocean Thermal Energy System includes shells made of composite material. The cold seawater intake can also be an elongated tube of composite material.
Abstract:
A heat transfer fabric (10) or material, the fabric or material comprising a conduit (14) containing a fluid and a focussing means (12) arranged to focus heat onto the conduit such that the fluid absorbs heat from adjacent the fabric and flows to a heat sinking means (16) where the absorbed heat is dissipated.
Abstract:
A modified structure of cooling tower body consists of tower body, air barrel (6), storage water basin (5) and packing support (3). It is featured as forming tower body by splicing multiple glass fibre side boards (2) with its top being set with water spraying device (9) and its bottom being connected to storage water basin, forming said glass fibre side board by hollow plate body prepared as binding two layers of glass fibre board together.
Abstract:
A heat exchanger of a ventilating system includes: heat exchange plates having first air passage through which indoor air being discharged to outside of a building passes and a second air passage through which outdoor air being introduced to the interior of the building passes which are sequentially formed: first corrugation plates attached to the first air passage; and second corrugation plates attached to the second air passage, wherein the heat exchange plates are made of a paper material with numerous fine holes that are able to generate a capillary phenomenon and loess which radiates far infrared ray. Heat exchange and moisture exchange between the indoor air and the outdoor air are performed simultaneously, and a cleaning function of removing a harmful material contained in outdoor air can be carried out.
Abstract:
A heat exchanger (10) having a fiber preform embedded in a matrix with a second discreet group of fibers (30) extending through the fiber preform to the surface of the matrix with the fibers being made of a heat conductive material and extend to cooling channels or tubes (12, 14) so as to improve the heat exchange therebetween.
