Problems solved by technology

[0005] However, in the casing of the mobile phone terminal described in Japanese Patent Application Laid-Open No. 2008-177275, the weight of the casing can be reduced. On the other hand, since the thermal conductivity of Al is insufficient, the heat is conducted from the heat source to the casing through the heat sink. The heat from the aluminum part of the body cannot be sufficiently conducted to the entire aluminum part, so there is a problem that heat cannot be sufficiently dissipated in the housing

Embodiment Construction

[0042] Hereinafter, embodiments embodying the present invention will be described based on the drawings.

[0043] First, refer to Figure 1 ~ Figure 3 , the internal structure of the portable device 100 according to one embodiment of the present invention will be described.

[0044] In the portable device 100 of this embodiment, as figure 1 and figure 2 As shown, a display 1, a casing 2, a substrate 3, and a battery 4 are arranged in this order from the upper side (Z1 side). Among them, the display 1 , the cabinet 2 and the substrate 3 are formed in a substantially rectangular shape having a length L1 of about 100 mm in the longitudinal direction and a length L2 of about 50 mm in the width direction when viewed from above. In addition, the battery 4 is formed in a substantially rectangular shape smaller than the substrate 3 in plan view.

[0045] The display 1 is composed of a liquid crystal display, an organic EL display, or the like, and has a function of displaying an ...

Abstract

The purpose of the present invention is to provide a chassis capable of reducing the weight and sufficiently radiating heat and a portable apparatus comprising the chassis. The chassis comprises a clad material to which an Al layer consisting of Al or an Al alloy, and a Cu layer consisting of Cu or a Cu alloy, and whose thermal conductivity is greater than the Al layer are bonded.

Description

technical field [0001] The present invention relates to, for example, a casing suitable for use in a device incorporating an electronic component that generates heat, and a portable device including the casing. Background technique [0002] Currently, in portable devices and the like, a case is used to protect a display unit for displaying an image from external impact. For example, Japanese Patent Application Laid-Open No. 2006-113589 discloses a display device including a panel unit and a casing made of SUS for fixing and supporting the panel unit. [0003] On the other hand, in recent years, weight reduction is desired in electronic devices such as portable devices. In this case, since SUS has a large specific gravity (about 7.8 specific gravity), it is difficult to reduce the weight of the casing and the display device in the structure described in Japanese Patent Laid-Open No. 2006-113589. Therefore, in order to reduce the weight of the casing, it has been proposed to...
