Research On The Heat Transfer Characteristics Of Flat Miniature Grooved Heat Pipe

Flat miniature grooved heat pipe(FMGHP) has attracted increasing attention from researchers for its prospect on cooling the micro-electronic elements.Some creative works have been done by foreign researchers,but it is still lack of relevent research in our country。This paper studies the FMGHP with grooves in one side of the plate in a detailed way based on the theoretic works made by the former researchers.This paper is consisted of two major parts:one deals with the general working performance of the FMGHP by setting up mathematic model and developing computer procedure,getting the datum related to the capillary flow and heat transfer, analysing the working characteristics of FMGHP in different working temperature,heat flux and inclination angle etc.In this part,the prediction of capillary and boiling limit are also included.The other major part studies the flow and heat transfer characteristics in the micro-film region formed by the meniscus attached on the metalic fin in the micro rectangular groove.Investigations on the influence of width of groove and other factors on heat transfer in this region have been made.The importance of this micro-region in the heat transfer of the entire heat pipe has been unveiled.The heat transfer characteristics gotten by this research could be used in design and application and also optimization of this kind of FMGHP.
