Abstract
DEVELOPMENT OF FLAT PLATE OSCILLATING HEAT PIPE AS A HEAT TRANSFER DEVICE
Highlights
As modern systems become smaller and more densely packed, the demands for effective heat transfer devices increases
A typical OHP is a small capillary tube which is bent into many turns with partially filled with working fluid as seen in Fig. 2.The ends of the tube may be connected to each other in closed loop, or welded shut in an open loop as seen in Fig. 2a & 2b.The unique characteristic of oscillating heat pipe is that there is no wick structure to return the condensate to the heating source there is no countercurrent flow between the liquid and vapour
Heat load is applied to one end of the heat pipe which is known as heat source, the working fluid is vaporize and vapour pressure is increases, so that liquid slugs and vapour plugs are formed
Summary
As modern systems become smaller and more densely packed, the demands for effective heat transfer devices increases. A typical OHP is a small capillary tube which is bent into many turns with partially filled with working fluid as seen in Fig. 2.The ends of the tube may be connected to each other in closed loop, or welded shut in an open loop as seen in Fig. 2a & 2b.The unique characteristic of oscillating heat pipe is that there is no wick structure to return the condensate to the heating source there is no countercurrent flow between the liquid and vapour. Heat load is applied to one end of the heat pipe which is known as heat source , the working fluid is vaporize and vapour pressure is increases, so that liquid slugs and vapour plugs are formed. Most investigation work is done with closed loop OHPs
