Application Of Heat Pipe Cold Plate Used In Electronics Cooling

Heat pipe cold plate is a kind of cooling method which is now widely used in electronics cooling. It has simple structure, high reliability, light weight and has no movable parts. Thus it is a new cooling instrument with a great prospect. This paper introduces several methods used in electronics cooling and advances in thermal design of electronics. A 2-dimension mathematic model was built for a heat pipe cold plate used in electronic equipments. The solution was gained with a boundary condition of constant heat flux. This article also analyzed the heat resistance of the whole heat pipe cold plate. According to the formula of overall resistance, it is pointed out that how to optimize the performance of the plate. In order to investigate the performance of the applied cold plate, a experiment was designed using different types of heat pipe cold plate, analyzing several factors such as gravity, air-flux, power of electronic. The result of the experiment can provide a reference for optimizing the performance of the heat pipe cold plate in application.
