Title:
COMBINED EVAPORATOR VAPOR CHAMBER AND MACHINING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/173471
Kind Code:
A1
Abstract:
Provided are a combined evaporator vapor chamber and a machining method therefor. The vapor chamber comprises an upper cover plate (1), a lower cover plate (2), an evaporator (3), a capillary structure and a support structure (5), wherein a mounting port is formed in the lower cover plate (2) and corresponds to a heat-source contact region; the evaporator (3) is combined with and connected to the lower cover plate (2) at the mounting port; the upper cover plate (1), the lower cover plate (2) and the evaporator (3) jointly form a chamber (6); the capillary structure and the support structure (5) are arranged in the chamber (6); and a phase change medium is injected into the chamber (6). The evaporator and the lower cover plate are separately designed and are then combined in an assembled manner, so that the difficulty of component machining is reduced, the usage amount of a material is reduced, the machining difficulty is decreased, and the cost of raw materials is also reduced.
