Embodiment ）

[0086] Next, refer to figure 2 , image 3 , Figure 5 ~ Figure 10 Describes the measurement of heat dissipation performance and the measurement of mechanical strength to confirm the effects of the present invention. However, unless otherwise specified, "thickness" and "plate thickness" mean average values.

[0087] In this embodiment, use image 3 The bottom plate 2 of the above embodiment is shown. Specifically, Examples 1 to 8 (reference Figure 7 ) A base plate 2 made of a composite material obtained by stacking the SUS layer 21 formed of SUS304, the Cu layer 22 formed of Cu, and the SUS layer 23 formed of SUS304 in this order. In addition, Examples 9 to 13 (reference Figure 8 ) A base plate 2 made of a composite material obtained by stacking the SUS layer 21 formed of SUS301, the Cu layer 22 formed of Cu, and the SUS layer 23 formed of SUS301 in this order.

[0088] In addition, in Examples 1 to 13, the thickness t1 (=t2+t3+t4, total thickness) of the bottom plate 2 was 0.3 ...

Abstract

This chassis (2) comprises a clad material obtained by roll bonding a first layer (21), which is formed from an austenitic stainless steel, a second layer (22), which is formed from Cu or a Cu alloy and which is laminated on the first layer, and a third layer (23), which is formed from an austenitic stainless steel and which is laminated on that side of the second layer which is opposite the first layer, wherein the thickness of the second layer is 15% or more of the thickness of the clad material.

Description

Technical field [0001] The present invention relates to a chassis suitable for use in portable devices with built-in electronic components accompanied by heat dissipation, and a method for manufacturing the chassis, and more particularly to a chassis using stainless steel and Cu, and a method for manufacturing the chassis. Background technique [0002] In the past, in portable devices and the like, in order to protect the display portion for displaying images from external impact, a base plate made of stainless steel with high mechanical strength has been used. For example, Japanese Patent Application Laid-Open No. 2006-113589 discloses a display device including a panel unit and a bottom plate for fixing and supporting the panel unit. In addition, although there is no clear description in Japanese Patent Application Laid-Open No. 2006-113589, it can be considered that the bottom plate of the display device is formed of stainless steel having a thickness of about 0.3 mm to about ...
