Description

Power supply for computers.

Object of the invention

The present invention relates to a source of power for computers, of those destined to transform the mains voltage in alternating at the different voltage levels in continuous for feeding the different components electronics that participate in a personal computer.

The object of the invention is to provide a extremely quiet power supply, not including noisy fans in it, all without detriment to cooling performance of it.

The invention thus falls within the scope of the power systems for computers.

Background of the invention

As personal computers or PCs are known, incorporate an internal power supply, in order to transform the mains voltage to which the computer is connected, that is 220 volts in alternating, at different levels of direct voltage of the different circuits or elements that participate in the computer, such as hard drive, motherboard, readers DVDs, etc.

This process of transformation and rectification carries with it the release of a large amount of heat, from so that for the proper functioning of said sources of food is necessary that they are coupled at least an electro-fan for cooling the device.

This type of fans are quite loud, so that noise can be very annoying to people who have to spend long periods of time in front of a computer, as is the case with the vast majority of workers.

Trying to ignore this problem are known sources called "silent", with a structure that allows to reduce the level of noise produced by the source to some levels that are around 17 dB.

However, these types of sources have a complex and consequently expensive structuring, in addition to said level of rumorosity would be equally desirable for reduce.

Description of the invention

The power supply that the invention proposes to solve the problem fully satisfactorily previously exposed, reducing the noise level to zero of it, because it does not incorporate electro-fans of any kind.

For this and more specifically, it is planned that from the conventional electrical structuring of any power supply, said electrical elements are lodge in a hermetically sealed housing, made of high material thermal conductivity, so that it is filled with insulating oil, of the type used in transformers electrical, acting the housing surface itself as a means of refrigeration, together with the aforementioned oil.

As is evident, the housing will be equipped with the classic windows for entry and exit of the corresponding power cables or connections of the power supply, the which will be properly sealed by gaskets tightness, cable glands or similar.

The structuring of the housing may be due to multiple design lines, albeit, and to improve transmission of heat, it will be equipped with established cooling fins on its surface.

In this way a source of power supply that does not require electric fans, lacking any noise generating element appreciable by the Username.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a representation schematic side elevation of a power supply for computers made in accordance with the purpose of this invention.

Figure 2.- Shows a perspective view from the source of the previous figure.

Preferred Embodiment of the Invention

In view of the figures outlined, and in Figure 1, can be seen as the source of power for computers that is recommended is constituted, as is conventional, from a printed circuit (1), in the that the different electronic components are established usually used in these types of devices to obtain the different voltage levels required at the exit of the source, components that can be grouped basically into three operational groups, a rectification and transformation module (2), protection elements (3), and a filtering module (4), being said circuit (1) connected to a power cable (5) for its connection to the electricity distribution network, and a plurality of output connectors (6) for connection of the source to the different electronic components that participate in the computer.

Well, according to the invention, the printed circuit (1) is housed inside a housing (7), preferably metallic, of a high conductivity material thermal, housing than in the practical example chosen It has a rectangular prismatic configuration, but it can vary according to different design lines, presenting in any case with a hermetic character, so that the space existing between the printed circuit (1) and the internal surface of the housing (7) is filled with electrically insulating oil from the type of those used in high electrical transformers power.

As previously mentioned, the external surface of the housing (7), which acts as an element of heat dissipation generated by circuit (1), may be equipped with cooling fins (8) established on different surface regions, enhancing heat transfer by convection

Finally, it should be noted that Essential power cables (5) and connections (6) associated to the printed circuit (1) will access the inside of the housing (7) through sealing gaskets or waterproof grommets (9) that prevent the outflow of oil (10) outside the Case.
