Abstract

PURPOSE:To realize an electronic equipment device of high performance keeping a fan fitted to the outer wall of the device unchanged in size and number of revolutions by a method wherein a case is prevented from being filled with heat released from an electronic substrate. CONSTITUTION:When a power supply switch is turned ON, functional parts which take charge of communications, displays, and calculations inside an electronic substrate 1 start to operate and release heat, so that heat is accumulated at a point distant from a heat exhaust vent of the electronic substrate 1 if a fan is limited in size and number of revolutions. A small auxiliary fan 5 is provided to an airflow path between an exhaust vent 7b and an air intake vent 7a serving to efficiently transmit heat inside an equipment to a cooling fan 3 and put an airflow formed between an air exhaust vent and an air intake vent in order. Therefore, heat standing at a point distant from an exhaust vent can be directed to the exhaust vent without increasing a fan fitted to the outer wall of an equipment in capacity, so that an electronic equipment device of this design can be enhanced in cooling effect.

2. Description of the Related Art Conventionally, heat generated by an LSI or a mechanical component mounted inside a device has been prevented from being trapped inside by scraping it out by a cooling fan arranged on the outer wall of the device.

[0003]

However, in the prior art, the arrangement of parts inside the equipment is very complicated, and it is not easy to exhaust heat only by the fan arranged on the outer wall of the equipment. Even if the wind flow is well designed, heat will stagnate at points far from the exhaust port. This problem increases the diameter of the fan. Although it is possible to solve the problem by increasing the rotation speed, there are problems such as restrictions from the structural design and an increase in noise.

It is an object of the present invention to provide a high-performance (high calorific value) electronic device device while maintaining the size and rotation speed (noise) of the fan on the outer wall of the device.

EXAMPLE An example of the present invention will be described below. In FIG. 1, reference numeral 1 denotes an electronic board which is composed of electronic parts and electronic circuits and has an arithmetic function, a communication function, or a display function.
Is a cooling fan that sucks or blows cooling air that removes heat generated from the electronic components and the electronic circuit, 2 is a power supply device that supplies power to the cooling fan 3 and the electronic substrate 1, and 7 is a power supply device 2 and an electronic device. A housing for accommodating the board 1 and the cooling fan 3, 7a is provided in the lower part of the housing 7 and is provided with the cooling air 4
An intake port for introducing the cooling air, an exhaust port 7b provided at an upper portion of the casing 7 for discharging the cooling air 4, and an exhaust port 7 for discharging the cooling air 4 inside the casing.
a is installed between a and the intake port 7b and is driven by the power supply device 2 to correct the distribution path of the cooling air 4 and
Is an auxiliary fan that enhances the air flow rate of the electronic board 1 and improves the cooling effect of the electronic substrate 1, and is a small auxiliary fan 5 for adjusting the air flow inside the equipment of the personal computer or workstation.
The electronic device apparatus is characterized by including the above, and preventing the heat generated by the parts located far from the cooling fan 3 prepared in advance at the exhaust port 7b from staying inside the device.

That is, 1 is an electronic board, which is used for arithmetic, communication,
Functional parts for displaying are installed.

Reference numeral 2 denotes a power source, and in a small computer, the cooling fan 3 is fixed so as to radiate heat not only inside the device but also inside the power source.

Reference numeral 3 denotes a cooling fan, which is located on the outer wall of the device and radiates the heat generated inside to the outside.

Reference numeral 4 represents a flow of wind, and a long arrow is drawn to show how the flow becomes steep near the fan.

Reference numeral 5 denotes a small-sized auxiliary fan, which realizes a system path through which the air flows, which is designed at the structural design stage, without increasing the performance of the cooling fan 3.

Reference numeral 6 denotes an LSI, which is a functional component for performing calculation, communication, and display.

When a power switch is turned on to use a microcomputer or a workstation, the functional parts in the electronic board 1 that control communication, display and calculation start operating. As a matter of course, each component generates heat, so if this heat is not released to the outside, the equipment will run out of heat and the function will stop.
In FIG. 1, heat is exhausted by the cooling fan 3 fixed to the power supply device 2 and, at the same time, the air flow is regulated by the small auxiliary fan 5. That is, when there is an upper limit to the size and rotation speed of a fan such as a small personal computer, heat cannot escape at a point far from the heat exhaust port of the electronic substrate 1 and stagnates. The small auxiliary fan 5 has an exhaust port 7b.
And is interposed in the air flow path between the intake ports 7a and efficiently transfers the heat inside the device to the cooling fan 3.

[0017]

According to the present invention, when the air passage from the exhaust port to the intake port is designed, even if the performance of the fan on the outer wall of the equipment is not improved, the heat stagnation at a point far from the exhaust port is exhausted. The cooling effect can be improved.
