本発明は、各種電子機器の構成に広く使用されるプリン
ト板の半導体チップを冷却する循環冷却回路のフィルタ
実装構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a filter mounting structure for a circulating cooling circuit that cools semiconductor chips on printed circuit boards that are widely used in the construction of various electronic devices.
最近、特に、大型電子機器に装着されるプリント板は大
型化、高密度化されてきたが、一方ではそのプリント板

の発熱量が増大しており、その半導体チップの冷却性能
に対する要求も大変酸しいものとなっている。Recently, the printed circuit boards installed in large electronic devices have become larger and more dense, but at the same time, the semiconductor chips mounted on these printed circuit boards have become even more densely integrated and their heat generation has increased. Therefore, the requirements for the cooling performance of semiconductor chips have become very demanding.
そのため、冷却効率の高い水を循環させて冷却する方法

のフィルタ実装構造が必要とされている。For this reason, a method of cooling by circulating water with high cooling efficiency has been adopted, but if minute impurities occur in this cooling water, they will adhere to the cooler that cools the semiconductor chips and change the fluid characteristics. At the same time, it deteriorates the cooling characteristics and pollutes the water, causing corrosion of the circulation cooling circuit. A bypass filter circuit is installed in the circulation cooling circuit in order to remove these impurities, but the circuit structure becomes complicated, so a new filter mounting structure for the circulation cooling circuit that can be constructed at low cost is needed. There is.

継手間に不純物を除去する汎用のフィルタ４を配したバ
イパス回路を設けている。The filter mounting structure of the circulating cooling circuit, which has been widely used in the past, consists of a tank l for pooling cooling water, as shown in Figure 3.
A cooler 3 that cools objects to be cooled, such as semiconductor chips, is installed on the inlet side of the tank, and a pump 2 that pumps the cooling water in the tank l in the direction of the arrow is installed on the other outlet side. A cooling water circulation circuit is formed by connecting pipes between the two. A bypass circuit is provided in which the inlet and outlet sides of the cooler 3 are separated by, for example, a T-shaped joint, and a general-purpose filter 4 for removing impurities is placed between the T-shaped joints.

水の例えば５μｍ以上の不純物を吸収して除去するよう
に構成されている。When the pump 2 is driven, the cooling water circulates between the tank 1 and the cooler 30 as shown by the arrow, but some of the cooling water flows through the bypass circuit and passes through the filter 4. The microbore 4-2 made of ion exchange resin or the like shown in FIG. 4 is built into the microbore 4-2 and is configured to absorb and remove impurities of, for example, 5 μm or more from the cooling water passing therethrough.

路の構成が高価となる。The problem with the filter mounting structure of the circulating cooling circuit described above is that part of the circulating cooling water passes through the bypass circuit filter, which absorbs and removes minute impurities contained in the entire cooling water. Therefore, the piping for the bypass circuit inside the electronic device becomes complicated, and the configuration of the circulation cooling circuit becomes expensive.

が困難になるという問題が生じている。Further, as shown in FIG. 4, the bypass circuit piping and the filter 4 are connected by a self-sealing coupler 4-4.
In addition, the filter 4 includes a filter case 41 and a microbore 4-
Since it is composed of many members such as the 2.0 ring 4-3, there is a problem in that it becomes difficult to replace and maintain the microbore 4-2 and the like due to clogging.

守費を安価にすることが可能となる。In the present invention, when the pump 2 of the circulation cooling circuit is driven, the outlet side of the tank 1 is depressurized and cooling water is sucked from the opening at the tip of the hollow shaft 14-1, and a part of the cooling water is drawn into the filter 14 by the suction force. Since the cooling water passes through the microbore 14-2, impurities contained in the cooling water are absorbed and removed by the microbore 14-2, thereby simplifying the configuration of the cooling water circulation circuit. The filter 14 installed inside the tank 1 can be easily removed, and the structure is a hollow shaft 14-1 with one end of the cylinder closed and a hole 14-13 penetrating from the outer periphery to the center hole.
The cylindrical microbore 14-2 is inserted into the hole 14-1a.
Since the microbore 14-2 is fitted into the microbore 14-2, it is easy to replace the microbore 14-2 if it becomes clogged, and the construction and maintenance costs of the circulation circuit can be reduced.
