A novel plat heat pipe heat sink for multi-chip was designed
and the thermal performance of the heat sink in different air speed
chips numbers and positions
heating power was experimentally investigated. The experimental results showed that the maximum heat transport capacity of the heat sink with one
two and three heat sources were 310W
390 W and 500 W respectively in the horizontal position
and 275W
408W
500W in the vertical application when the chips temperature was less than 80℃ and the ambient temperature was 20℃. For the flat heat pipe heat sink
multiple chips cooling can dissipate more heat than unique source. The results were found to agree well with the experimental data about the thermal spreading effect of the flat heat pipe. It was shown that flat heat pipe accords with the requirements of electronic devices cooling.
