Abstract
(EN) A vapor chamber, comprising a first cover panel (100) and a second cover panel (200) arranged opposite to the first cover panel (100) and covering the first cover panel (100). The side of the first cover panel (100) near to the second cover panel (200) is indented away from the second cover panel (200) to form a first recess (101), and the first cover panel (100) and the second cover panel (200) enclose a sealed space (10) filled with a working fluid. The second cover panel (200) comprises a first copper plating layer (210) that abuts the first cover panel (100), a second copper plating layer (220) arranged opposite to the first copper plating layer (210), and a support panel (230) sandwiched between the first copper plating layer (210) and the second copper plating layer (220). The support panel (230) is penetratingly provided with a plurality of through holes (231). The second cover panel (200) further comprises connecting copper pillars (240) filling the through holes (231) and communicating the first copper plating layer (210) and the second copper plating layer (220). By means of the supporting role of the support panel (230), the quality of the second cover panel (200) is made sufficiently strong, and the panel is not easily broken. By means of the connecting copper pillars (240), the first copper plating layer (210) and the second copper plating layer (220) are communicated, thus being able to rapidly conduct heat out from the sealing space (10), and thereby improving the heat dissipation effect of the vapor chamber.
(FR) L'invention concerne une chambre à vapeur, comprenant un premier panneau de couverture (100) et un second panneau de couverture (200) disposé à l'opposé du premier panneau de couverture (100) et couvrant le premier panneau de couverture (100). Le côté du premier panneau de couverture (100) à proximité du second panneau de couverture (200) est indenté à l'écart du second panneau de couverture (200) pour former un premier évidement (101), et le premier panneau de couverture (100) et le second panneau de couverture (200) enferment un espace scellé (10) rempli d'un fluide de travail. Le second panneau de couverture (200) comprend une première couche de placage de cuivre (210) qui vient en butée contre le premier panneau de couverture (100), une seconde couche de placage de cuivre (220) disposée à l'opposé de la première couche de placage de cuivre (210), et un panneau de support (230) pris en sandwich entre la première couche de placage de cuivre (210) et la seconde couche de placage de cuivre (220). Le panneau de support (230) est pourvu de manière pénétrante d'une pluralité de trous débouchants (231). Le second panneau de couverture (200) comprend en outre des colonnes de cuivre de liaison (240) remplissant les trous débouchants (231) et faisant communiquer la première couche de placage de cuivre (210) et la seconde couche de placage de cuivre (220). Grâce au rôle de support du panneau de support (230), la qualité du second panneau de couverture (200) est rendue suffisamment solide, et le panneau ne peut pas se casser facilement. Grâce aux colonnes de cuivre de liaison (240), la première couche de placage de cuivre (210) et la seconde couche de placage de cuivre (220) sont mises en communication, ce qui permet de conduire rapidement la chaleur hors de l'espace d'étanchéité (10) et d'améliorer ainsi l'effet de dissipation de la chaleur de la chambre à vapeur.
(ZH) 一种均温板,包括第一盖板(100)以及与第一盖板(100)相对设置且盖设在第一盖板(100)上的第二盖板(200),第一盖板(100)靠近第二盖板(200)的一侧向远离第二盖板(200)凹陷形成第一凹槽(101),第一盖板(100)与第二盖板(200)围合形成填充有工作液体的封闭空间(10);其中,第二盖板(200)包括与第一盖板(100)相抵接的第一铜镀层(210)、与第一铜镀层(210)相对设置的第二铜镀层(220)以及夹设在第一铜镀层(210)和第二铜镀层(220)之间的支撑板(230),支撑板(230)上贯穿开设有若干通孔(231),第二盖板(200)还包括填充在通孔(231)内且将第一铜镀层(210)和第二铜镀层(220)连通的连接铜柱(240)。通过支撑板(230)的支撑作用,使第二盖板(200)的质量强度足够强,不易损坏,通过连接铜柱(240)将第一铜镀层(210)和第二铜镀层(220)连通,能够快速将封闭空间(10)内的热量导出,从而使均温板的散热效果更佳。
