    • What is disclosed is an apparatus for determining the cooling characteristics of a cooling device used for transferring heat from an electronic device. The apparatus comprising a cooling device thermally coupled to a heat pipe. The heat pipe having an exposed surface for the selective application of heat thereon. A localized heat source is selectively applied to at least one region of the exposed surface. The heat source preferably capable of being varied both positionally relative to the exposed surface and in heat intensity. A heat shield is preferably positioned around the exposed surface of the heat pipe to isolate the operational cooling device from the localized heat source. A temperature detector repeatedly measures a temperature distribution across the exposed surface while the cooling device is in a heat transfer mode. The temperature distribution is then used to thermally characterize the cooling device.
    • 所公开的是用于确定用于从电子设备传递热量的冷却装置的冷却特性的装置。 该装置包括热耦合到热管的冷却装置。 该热管具有用于选择性地在其上施加热量的暴露表面。 选择性地将局部热源施加到暴露表面的至少一个区域。 热源优选地能够相对于暴露的表面和热强度都在位置上变化。 优选地,隔热板围绕热管的暴露表面定位,以将操作冷却装置与局部热源隔离。 当冷却装置处于传热模式时,温度检测器重复测量暴露表面上的温度分布。 然后使用温度分布来热定形冷却装置。
