Process and assembly for flush connecting evaporator sections of juxtaposed heat pipes to a fixing base

Abstract

A process for flush connecting evaporator sections of juxtaposed heat pipes to a fixing base and forming a plane includes the steps of: providing a fixing base with its bottom surface having an accommodating trough; providing at least two heat pipes each having an evaporator section and a condenser section; disposing the evaporator sections of the heat pipes in the accommodating trough; and machining the evaporator sections of the juxtaposed heat pipes, thereby forming a plane on the evaporator sections of the heat pipe. Via the above process, the evaporator sections of the heat pipes can be juxtaposed in and flush connected to the fixing base, thereby increasing the contact area between the evaporator sections of the heat pipes and a heat-generating element. It further provides an assembly for flush connecting evaporator sections of juxtaposed heat pipes to a fixing base and forming a plane.
