Abstract

PURPOSE:To perform air cooling effectively and to prevent damage due to a voltage drop, etc., by partitioning a power source part and board part in each hierarchy and cooling the power sources through a heat exchanger, cooling the board parts in a conventional way, and supplying electric power to every hierarchy through short buses. CONSTITUTION:A package part 3 for printed boards PWB and a power source package part 4 are partitioned with a partitioning plate 2. A power source is provided to each hierarchy, and buses B1-B6 to printed boards penetrate the partitioning plate 2. The 1st heat exchangers T1-T6 connected in series are fitted to the power sources P1-P6 in the middle of a circulating passage 5 for a refrigerant. The 2nd heat exchanger 7 performs heat exchange between the circulating passage 5 and a flow passage 6 for water and air. A suction unit 8 and discharge unit 9 cool the board part. Refrigerants in the heat exchangers T1-T6 are heated by the power sources P1-P6 and are supplied to the heat exchanger 7 through the flow passage 5; and the heat that the refrigerant has is given to the air or water of the flow passage 6, and the refrigerant returns to the heat exchangers T1-T6.

Description

[Detailed Description of the Invention] This invention is divided into hierarchies within the housing, and H'[
As is well known, the inside of the housing is divided into PLT layers.
There are multiple printed circuit boards with no electronic components mounted on the 8th floor.

Electric power is supplied to the printed circuit board K from one or more power sources.

By the way, in recent years, in JI machines, it is common to divide the power supply into multiple parts and supply power to the safe functions (b) separately, and it is not possible to supply power from a single power supply instead of using a power supply. It's becoming more and more important.

Therefore, each level of emotion I placed in the forest! !
It is desirable to supply the power source to the circuit over a short distance as much as possible, which can also avoid the voltage drop at the power source.

However, it is safe to place the power supply adjacent to the functional circuit, taking into account the heat dissipation caused by the power supply.

The present invention was developed based on this point of view, and will be explained below using an example 6111i shown in the figure.

In the figure, each layer is divided into n layers of IIIH total sm + Ft''FaH layer, and each)'1 layer has tX
A package shelf is installed and the printed card PWB is mounted on the shelf. 121 is the PWB mounting part (3:) and the power supply replacement part (
4) It is a partition plate that separates the money. The power supply P, % P, which is connected to a commercial power line or main power supply (not shown), is also arranged in a hierarchical manner in the power supply mounting part 141, which is divided into layers. The output of power supply P1 is supplied to the printed board of layer Fl, and the output of power supply P is supplied to layer F2 of layer F2.
is supplied to the printed circuit board.

B1-86 corresponds to the power output! - An electric wire or cable for supplying electronic parts, and passes through the partition plate.

It extracts the heat generated from the valley gap, and is a flow path in which air or water flows through the circulation flow path (provided in the middle of 51; 6) in which a refrigerant such as 7 Leon is circulated.

In addition, the heat exchanger (7: and flow path (6) of I42 are connected to the power supply p
It is located at a place art from t to P6, and is provided on the back of the casing, for example.

In addition, 181r [intake unit that takes in outside air to cool the printed circuit board mounting section], 191t'! This is an exhaust fan unit.

Since this output IN is as described above, the medium in the lth heat exchange '@T1 to T6 is the power supply P! 〜P6 So, the heat generated from jL is used to heat fL, expand, and become under pressure.It passes through the flow path (51) shown by the dotted arrow line and is transferred to the second heat exchanger (7), where it is heated. The heat generated by the refrigerant is 1kfL, which is given to the air and water, which then lowers the pressure by increasing its width and returns to the 1st and 8th heat vessel 1゛鳳~1゛6.

In addition, the flow path +61 tl-flow fL air and water flow l
For example, even if it is supplied from an empty equipment's reactor, it will be too small.

10,000, the printed circuit board mounting part (3) is accommodated by the intake fan unit (8) and is cooled by the air being exhausted by the exhaust fan unit 191.

Since this invention has the above-mentioned features, it is possible to effectively decorate the printed board by using a different method for printing with a large plate [#Pt~P6μ], and using electric polishing force for printing. Not affected by heat. Ten thousand.

The printed circuit board was constructed in the usual manner and then discarded. Moreover, since the electric gap is minimized over a short distance in each layer, it is possible to prevent malfunctions of functional circuits due to voltage drops when power is supplied and external noise that tends to occur on long power lines.
