Title:
VAPOR CHAMBER
Document Type and Number:
WIPO Patent Application WO/2018/198350
Kind Code:
A1
Abstract:
This vapor chamber (1) has a casing comprising a first sheet (2) and a second sheet (3) facing one another, with the outer edges thereof bonded to one another, a column (5) provided between the first sheet (2) and the second sheet (3) to support the same from the inside, and operating fluid sealed within the casing (4). The first sheet (2) and the second sheet (3) do not have corners with angles less than 90°C between the junction (6) and the closest column (5) to the junction (6), and satisfy formulae 1 to 3 below. Formula 1: c≥1.8×b/a+0.270, Formula 2: 0.016≤b/a≤0.125, Formula 3: b≤0.500 [In the formulae, a is the distance (in mm) from the position at which deformation of the sheet starts to the end of the junction, b is the distance (in mm) between the first sheet and the second sheet at the position at which deformation of the sheet starts, and c is the width (in mm) of the junction.]
