Benefits of technology
[0009] Then, an object according to the present invention, being accomplished by taking the drawbacks of the conventional arts mentioned above into the consideration thereof, it is to provide a radiator having the structure, so that it can be easily disposed even within the narrow space remaining within the housing, fitting thereof, and can be altered in the outer configuration thereof, as well as, can be manufactured cheaply, thereby to provide an electronic apparatus having the liquid cooling system therein, which can obtain the optimal cooling characteristics with using such the radiator, and further a manufacturing method of such the radiator.
Problems solved by technology
However, with such the radiator of the conventional arts, in particular, being made up with attaching the heat radiation fins on the metal thin tube zigzagged, which is actually used widely in the personal computer, being so-called the desktop type, and / or the server, etc., it has a drawback that the production process thereof is complex and takes much man-hour, therefore is relatively expensive on costs thereof.
On the other hand, for such computer of the desktop-type personal and the server, etc., in particular, due to the demands upon small-sizing and space-saving made in recent years, and also the recent currency of lowering the selling price thereof, it is not always possible to keep an enough space therein, to dispose the radiator having such the predetermined shape or configuration therein, so as obtain the optimal cooling characteristics or performances therefrom.
However, actually, there are rather cases very often, wherein the radiator must be stuff into a narrow space remaining within an inside of the housing, forcefully.
In such the cases, it is impossible to obtain the cooling function, fully from the radiator, and therefore there is a problem that the distinctive character of the liquid cooling system cannot be achieved in the actual use thereof.
In addition thereto, with such the conventional arts mentioned above, also due to the complex manufacturing process thereof, it is difficult to manufacture the radiator having an outer shape or configuration being freely variable fitting to the narrow space remaining within the housing.

Embodiment Construction
[0022] Hereinafter, explanation will be given on the embodiments according to the present invention, in details thereof, by referring to the drawings attached herewith.
[0023] First, FIG. 2 attached herewith shows an example of the entire structure of an electronic apparatus having a liquid cooling system therein, according to one embodiment of the present invention. However, in this embodiment, there is shown a case, where the present invention is applied into a main portion of a personal computer, such as, of the desktop type, for example.
[0024] As shown in the figure, the main part or portion of the desktop type personal computer comprises a housing 100, which is formed from a metal plate into a cubic shape thereof, for example, and on a front panel portion 101 thereof are provided various kinds of switches, including an electric power switch therein, and indicator lamps, etc. Also, within an inside thereof is disposed a driver device 102, for driving various kinds of external i...

Abstract
In an electronic apparatus having a liquid cooling system, and enabling to obtain the optical cooling characteristic or capacitor with an aid of a radiator, which can be disposed or located fitting to a narrow space within a housing thereof, wherein a CPU 200 in deed of cooling thereof is installed within the housing 100, and the liquid cooling system for cooling the CPU comprises a cooling jacket 50 and a radiator therein, and wherein the radiator has a pair of headers 62 and 62, being constructed with disposing a large number of metal thin tubes 61, 61 . . . therebetween, aligning in parallel to each other, and can be change in an outer configuration thereof, easily and freely, and therefore it can be positioned even in the narrow space. Further, a cooling fan 64 or 66 for cooling the radiator 60 compulsively may be disposed therein, and in that case; it is also possible to maintain a position for setting up a motor 65 or 67 for rotationally driving the fan, including therein.
Description
BACKGROUND OF THE INVENTION [0001] The present invention relates to an electronic apparatus, such as, a personal computer, being so-called a desktop-type or a notebook-type, or a server, etc., and in particular, it relates to an electronic apparatus having a liquid cooling system therein, thereby being able to cool down a heat-generation element mounted within an inside thereof, such as, a semiconductor integrated circuit (IC), effectively with an aid of a liquid refrigerant or coolant, and further the structure of a radiator suitable thereto and a manufacturing method thereof. [0002] In order to maintain a normal operation thereof, cooling is necessary for the heat-generation element, such as, the semiconductor IC element, being mounted within an electronic apparatus, including a personal computer, of so-called the desktop-type or the notebook-type, as well as, a server, etc., and in particular, the heat-generation element, such as, a CPU (Central Processing Unit), as a representat...
