摘要： A modular thermal energy storage system for storing and transferring thermal energy at a wide range of temperatures. The system includes processing control circuitry, heat transfer fluid (HTF), piping, valves, pumps, a thermal energy source, and a reconfigurable thermal energy storage (TES) tank implemented in one or more insulated shipping containers. Different types of replaceable thermal energy storage material in the TES tank can store thermal energy in a range of −30° F. to temperatures greater than +200° F. The system receives HTF from a customer load and charges the HTF to a desired temperature. Charged HTF in the TES tank transfers thermal energy to and from the storage material. When the stored thermal energy is needed, the system passes a non-charged thermal fluid through the TES tank to draw out the thermal energy through the charged HTF, and transfers the thermal energy to the customer load.

摘要： The subject invention pertains to a method and apparatus for storing thermal energy. The subject thermal energy storage apparatus can function as a heat absorber in a cooling system. A cooling system can incorporate a cooling cycle that utilizes thermal energy storage and has two coolant loops. The primary cooling loop acquires the waste heat from a heat source, such as an electronic device, by heat transfer to the primary coolant via, for example, a sensible heat process (where sensible heat is heat absorbed or transmitted by a substance during a change in temperature which is not accompanied by a change of state) or by evaporating the primary coolant through a latent heat phase change process. The waste heat absorbed by the primary coolant is transferred to the host material of the heat absorber. The subject invention uses a high thermal conductivity host material to house a lower thermal conductivity phase change material, in order to achieve a thermal energy absorber that has a high effective thermal conductivity. In a specific embodiment, the high thermal conductivity host material has have voids within the structure that can be filled by the phase change material. The increased surface area of phase change material in thermal contact with the host material per volume of phase change material allows the thermal energy to be stored or released quickly, because of the enhanced effective thermal conductivity.
摘要翻译：本发明涉及一种用于存储热能的方法和装置。本发明的热能储存装置可用作冷却系统中的吸热器。冷却系统可以包含利用热能储存并具有两个冷却剂回路的冷却循环。主冷却回路通过例如显热处理（其中显热被吸收或物质在变化期间传递的显热）过程通过热传递到主冷却剂来获得来自诸如电子设备的热源的废热在不伴随状态变化的温度下）或通过潜热相变过程蒸发一次冷却剂。由主冷却剂吸收的废热转移到吸热体的主体材料。本发明使用高导热性的主体材料来容纳较低的热导率相变材料，以便实现具有高有效热导率的热能吸收体。在具体实施方案中，高导热性主体材料在结构内具有可被相变材料填充的空隙。由于增加的有效导热率，相变材料与主体材料每体积相变材料的热接触增加的表面积允许热能快速储存或释放。
