Boiling and Two-phase flow in microgap channel has been recently proposed for cooling the heat sources directly in application of thermal management for electronic devices. In this study, the boiling heat transfer and gas-liquid flow on the heated surface in microgap is investigated experimentally by using Temperature-Sensitive Paint (TSP). Experiments are performed in a single rectangular channel having microgap of 10 mm width, 35 mm heated length and 0.5 mm height using FC-72. TSP coated on the heated wall is used to obtain the local temperatures and subsequently local heat transfer coefficients. Flow rate of FC-72 is 200 mg/s and heated water at 339 K is used as a heat source for boiling of the test fluid. Observation of gas-liquid behavior and measurement of the temperature distributions on the heated surface could be achieved at the same time by TSP. As a result, the heat flux of the rear side of a boiling bubble is 1.2-1.5 times higher than that of the front side of a bubble.

最近，已经提出了在微型AP通道中的沸腾和两相流，用于直接在电子设备的热管理中冷却热源。在这项研究中，通过使用温度敏感的油漆（TSP）研究了微型AP的加热表面上的沸腾传热和气体流动。实验是在使用FC-72的单个矩形通道中进行的，其宽度为10 mm，加热长度为35 mm，高度为0.5 mm。在加热壁上涂层的TSP用于获得局部温度，然后使用局部传热系数。 FC-72的流速为200 mg/s，在339 K处的加热水用作测试液沸腾的热源。 TSP可以同时实现气体液体行为的观察和加热表面温度分布的测量。结果，沸腾气泡后侧的热通量比气泡前侧的热通量高1.2-1.5倍。
