摘要：

Experimental　investigations　of　flat　plate　heat　pipes　(FPHP)　are　presented.　The　capillary　structures　of　the　three　tested　FPHPs　are　intersected　narrow　grooves　on　evaporation　surface　(FPHP　1),　interlaced　channels　(FPHP　2)　and　intersected　micro-grooves　on　both　evaporation　surface　and　condensation　surface　(FPHP　3).　The　experimental　results　showed　that　FPHP　3　has　the　smallest　thermal　resistance　and　the　best　axial　heat　conduction　ability,　while　FPHP　2　has　the　largest　thermal　resistance　and　the　poorest　axial　heat　conduction　ability.　FPHP　3　also　has　the　best　radial　temperature-leveling　performance　while　the　other　two　are　of　a　similar　radial　temperature-leveling　ability.　Therefore,　the　intersected　micro-grooves　on　both　evaporation　surface　and　condensation　surface　are　the　best　capillary　structure　for　flat　plate　heat　pipes.　The　reason　is　perhaps　the　structure　enhances　both　the　boiling　heat　transfer　on　the　evaporation　surface　and　the　condensation　heat　transfer　on　the　condensation　surface.　©　All　Rights　Reserved.
