Description

[Detailed description of the invention] [Industrial field of application] This invention provides a cooling water supply device that circulates and supplies a fixed amount of cooling water to a heat generating part of an electronic device or the like to cool the heat generating part to a constant temperature. This invention relates to a filtration device that filters cooling water midway through a closed cooling water circuit.

[Conventional technology]

As this type of cooling water supply device, one shown in FIG. 3 is known. In the figure, 1 is an object to be cooled such as a heat generating part of an electronic device, 2 is a pipe through which cooling water flows,
3 is a pump that circulates cooling water in the direction of the arrow; 4
6 is an air-cooled heat exchanger that receives cold outside air by a fan 5 and cools the cooling water; 6 is a reserve tank whose upper surface is open and includes a porous rectifier plate 7 between the cooling water inlet 6a and the outlet 6b; 8; 9 is a cooling body disposed in a heat-transfer manner within the object to be cooled 1, and 9 is a filtration device for purifying cooling water. Each device from the pump 3 to the filtration device 9 is connected by the piping 2 to form a closed cooling water circuit 10.

The cooling water supply device circulates and supplies the cooling water cooled by the heat exchanger 4 to the cooling body 8 housed in the object to be cooled 1 to cool the object to be cooled 1 to a constant temperature. Problems that occur while the cooling water is circulating in the closed cooling water circuit 10, such as expansion, contraction, evaporation, and reduction due to small leakage of the cooling water due to temperature, and fluctuations in the pressure of the cooling water when starting the pump, etc., are reserved. tank 6
Microscopic foreign matter that is absorbed by the cooling water and further mixed into the cooling water during circulation is collected by the filtration device 9, and the cooling water is always supplied to the object 1 to be cooled in a stable state with constant pressure and constant quantity and in an extremely clean state. Ru.

As shown in FIG. 4, the filtration device 9 is installed in a case body 11 equipped with piping connections 11a and 11b forming the inlet and outlet of the cooling water, and an insertion opening 11c into which the cap 12 is removably screwed. 1
A filter 13 is installed in a removable manner from 1c. The cooling water flowing in from the pipe connection part 11a passes through the filter 13, and at this time, foreign matter in the cooling water is caught by the filter 13, and flows out from the pipe connection part 11b. The foreign matter collected by the filter 13 is removed by periodically removing the case body 11 from the piping 2 and removing the filter 13 from the case body 1.
1 and removed.

[Problem that the invention attempts to solve]

By the way, in the conventional cooling water supply device, the foreign matter removal work to take out the foreign matter collected in the filtration device 9 is
The cooling water in the pipe 2 had to be removed once, which was an extremely difficult task.

The object of this invention is to provide a filtration device for a cooling water supply device that can remove foreign matter extremely easily without requiring removal of the cooling water in the pipe 2.

[Means for solving problems]

In order to achieve the above object, this invention includes a reserve tank with separate inlet and outlet for cooling water, a cooling water circulation pump, a heat exchanger, and a cooling body installed in the object to be cooled. In the cooling water supply device, a closed cooling water circuit is configured by connecting with A strainer having a cylindrical rising part on the outer periphery of the filter and having a handle, a cylindrical depression in the bottom of the reserve tank, the rising part of the strainer removably fitting inside the strainer, and a cooling water outlet in the center. A filtration device is constituted by the strainer storage section with an opening.

[Effect]

While the cooling water passes through the reserve tank, foreign matter is collected in the strainer, and this strainer can be removed from the reserve tank as is. Therefore, the work of removing foreign matter becomes extremely easy.

〔Example〕

1 and 2 show an embodiment of this invention, and parts common or identical to those in FIGS. 3 and 4 are designated by the same reference numerals.

In FIGS. 1 and 2, a filtration device 9 is installed in a reserve tank 6. Reference numeral 21 denotes a strainer, which includes an umbrella-shaped filter 22, a cylindrical rising portion 23 rising from the outer periphery of this filter 22, and the filter 2.
2 and a handle 24 extending upward. 6
Reference numeral 1 designates a strainer storage portion in which a part of the bottom plate of the reserve tank 6 is recessed into a cylindrical shape so that the rising portion 23 of the strainer 21 fits therein, and a cooling water outlet 6b opens at the center thereof. The current plate 7 is provided in a cylindrical shape above the strainer storage section 61.

In the above-described configuration, the strainer 21 is removably housed in the strainer housing 61 using the current plate 7 as a guide. The cooling water flowing in the direction of the arrow in the closed cooling water circuit 10 (FIG. 3) enters the reserve tank 6 from the inlet 6a, flows toward the strainer 21 while being rectified by the rectifier plate 7, passes through the filter 22, and flows out from the outlet 6b. do. Foreign matter in the cooling water is caught by the filter 22 and collected in a ring-shaped trough 25 formed between the filter 22 and the rising portion 23. However, the strainer 21 is periodically removed from the handle 2.
4 and is easily taken out from the reserve tank 6, and the foreign matter collected in the trough 25 is discarded. Then, the strainer 21 is again installed in the strainer storage section 61. In this way, the foreign matter removal work does not necessarily require removing the cooling water inside the pipe 2, but also removes the case body 11 from the pipe 2 as in the conventional case, removes the cap 12 from the case body 11, and then pulls out the filter 13. This eliminates troublesome work such as, and is extremely easy to perform.

[Effect of idea]

According to this invention, the umbrella-shaped slope forms a filter, and a cylindrical rising part is provided on the outer periphery of the filter,
and a strainer having a handle, and a strainer storage part that is recessed into a cylindrical shape at the bottom of the reserve tank, into which the rising part of the strainer is removably fitted, and in which the outlet of the cooling water opens in the center. Since the apparatus is configured, it is possible to dispose of the collected foreign matter without discharging the cooling water in the closed cooling water circuit, and the work of removing foreign matter can be performed extremely easily.
