ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a computer host, and more particularly to a portable computer host without any user interface.
2. Description of the Prior Art
The approaches of modern technologies bring computer size smaller than before. Nowadays, although desktop PCs and portable computer such as notebook computers or handhold PCs can be respectively employed as a still host or a movable host, one fatal disadvantage remains on all the currently used computers. Please refer to FIG.
1
(
a
) and FIG.
1
(
b
), which depicts perspective views of a desktop PC
10
and a notebook computer
20
, respectively. As known by the skilled persons, the desktop PC
10
is unsuitable for frequently moving because of volume and weight. On the other hand, the notebook computer
20
usually has 3-5 kilograms because user interface such as LCD
12
and keyboard
14
must be standard equipment. Accordingly, a bottleneck evidently appears at degrading the notebook size because the sizes of the aforementioned user interface can not be infinitely reduced. For example, users may feel uncomfortable at visual when looking at a LCD
12
with too small size. Furthermore, it is not so convenient for use when a keyboard
14
composed of buttons having size smaller than a human's finger.
A summary about the above description is made as below. For the traditional personal computer, even the notebook computer, the interface between the user and the computer, such as the monitor and the keyboard, occupies too much volume. However, contradiction is that further reducing the volume of the interface between the user and the computer is not a proper solution because of inconvenience operations.
SUMMARY OF THE INVENTION
The present invention discloses a portable computer host without any user interface. The portable computer host includes a mother board, a CPU, an auxiliary memory, a main memory, at least one port and a housing. Among these, the mother board has an upper surface and a lower surface. The CPU is placed on the upper surface and electrically coupled to the mother board via cables. The auxiliary memory is placed on the upper surface and electrically coupled to the mother board via the cables. The main memory is placed on the lower surface and electrically coupled to the CPU via the cables. Via a socket, the CPU is coupled to the upper surface of the mother board. Additionally, a heat sink is attached to the CPU to dissipate the heat generated by the CPU. At least one connecting port is placed along the peripheries of the mother board. Via the connecting ports, user interfaces such as a monitor and a keyboard can be connected to the disclosed portable computer.
The housing consists of a lower case and an upper case. Among these, the lower case holds the mother board and encapsulates the lower surface. The upper case covers the upper surface of the mother board. Additionally, the upper case has a plurality of air inlets and at least one exhaust outlet. The air inlets of the upper case serve as the intake of fresh air. Via the air inlets, the fresh air is introduced into the CPU by the fan. Then, via the exhaust outlet, the heat generated by the CPU is exhausted. Accordingly, the problem caused by the heat generated by the CPU is solved. By coupling the upper case to the lower case, the mother board and the above elements are sealed.
