Description

Parts cooling apparatus for personal computer communication equipments and electric / electronic equipments}

The present invention relates to a personal computer (PC), communication equipment, and electric / electronic device parts cooling apparatus, and more particularly, to the personal computer (PC), communication equipment and electrical / electronic devices when driving the various components attached thereto. The present invention relates to a personal computer (PC), a communication device, and an electric / electronic device component cooling device capable of more efficiently cooling a component by using a closed wind driven by a blower fan provided to discharge heat to the outside. .

In general, personal computers (PCs), communication equipments, and electrical / electronic devices are connected to each other electrically through wires or cables, or through printed circuit boards. It is organically connected to each other, and can be operated or controlled by the operation of these component elements.

Due to the development of electronic technology, component devices constituting such equipments have been enhanced in functions, faster in operation and processing speed, and smaller in size.

However, in the case of component devices having the same area in proportion to the development of the technology, the faster the processing speed, the faster the electron speed is, so that the component devices generate more thermal energy therein.

Due to the heat generated from these component elements, the life of the component is shortened or its function is deteriorated. In some cases, the adjacent component elements may be adversely affected, and in some cases, may cause malfunction or inability to process data. To this end, a cooling device for cooling them is installed in a component or a main body in which thermal energy is generated.

As an example, as shown in FIG. 1, a cooling apparatus installed in a main body of a computer is as follows.

That is, the cooling device 10 includes a heat sink 12 in which a plurality of heat sink fins 12a are integrally formed so as to be seated on the upper surface of the central processing unit 30 fixed to the printed circuit board 20, and the heat sink fins 12a. Receiving power from the power supply unit 40 is provided by the fastening means not shown in the detachable is made of a cooling fan 14 for blowing air.

The cooling device 10 is mounted and fixed to the central processing unit 30 to drive the computer. The cooling device 10 is supplied with electricity from the power supply unit 40 to radiate the fins 12a of the heat sink 12. Cooling fan 14, which is provided to be detachable to the drive by driving the air to the heat sink fin (12a) and the heat sink (12) to dissipate heat energy generated from the heat generating parts, that is, the central processing unit (30) Cooled.

However, since the conventional cooling device cools the heat generating parts by a cooling fan driven by receiving power from a power supply, power consumption is not only consumed, but there is a problem inevitably accompanied by mechanical noise due to the cooling fan driving.

In addition, electromagnetic noise is generated by driving the cooling fan of the cooling device, such that a malfunction of the equipment occurs in the case of high-frequency communication equipment.

In addition, in recent years, when the use of the central processing unit has been significantly improved, a corresponding cooling device should be used. However, due to the characteristics of the device, the size of the heat sink must be limited by the narrow installation space, and the cooling fan accompanying the noise is noisy. Due to the increase in the number of revolutions, such as due to the heat generation of the central processing unit, there was a problem such as shortening the life of the parts and causes a decrease in function.

The present invention is devised to solve the above problems, the heat absorbing means is installed in the heat generating parts that generate heat energy during communication equipment, electrical / electronic devices and computers, and the heat dissipation means in the power supply unit in which the blower fan is installed. In addition, by configuring a cooling device filled with a refrigerant circulating inwardly, the use of a personal computer (PC), communication equipment, and electricity that not only reduces electric power use but also provides a cooling device corresponding to heat generating parts. Its purpose is to provide a cooling device for electronic components.
