Heat-pipe engine structure

Abstract

A heat-pipe engine structure applicable to heat-exchange system. The heat-pipe engine structure includes a metal mesh laminate composed of more than two metal meshes which are tightly laminated with each other to form numerous meshes several times the unlaminated meshes of any original metal mesh. An upper metal film and a lower metal film are respectively bonded to upper and lower faces of the metal mesh laminate. The peripheries of the metal films are sealed to form a housing enclosing the metal mesh laminate. The meshes of the metal mesh laminate form a first nature vapor chamber. A liquid ingress and a vapor egress are formed on the periphery of the housing in different positions for externally connecting with a circulating loop to form a loop heat-pipe for one-way circulation of incoming liquid and outgoing vapor. The meshes of the metal mesh laminate are densely and evenly distributed in as the porous space in the housing for effectively conducting the working fluid to achieve better heat evaporation effect. In heat-exchange procedure, the working fluid is quickly changed between two phases to enhance the circulation. The laminated porous meshes form enough capillary pressure that meniscus in the engine wick supports enough pressure to overcome total system pressure drops from loop.
