Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cooling water supply device for water-cooling devices that generate a large amount of heat, such as large-scale electronic computers.

[Prior art]

The reality is that conventional cooling water supply devices of this type are individually designed and manufactured according to the installation conditions and computer scale of each user. Therefore, mass production effects cannot be expected, costs increase, and it takes a long time from order receipt to delivery. Furthermore, once the equipment has been delivered, it is difficult to change the cooling capacity or the cooling method (air cooling or water cooling, etc.), resulting in the need to replace the entire equipment.

Especially now that large computers are becoming extremely dense and the computer bodies are becoming smaller, it is desirable that the cooling equipment for these computers be downsized to the minimum necessary and that the cooling capacity can be easily changed in accordance with changes in the computer's capacity.

In an example that has been realized recently, as shown in Figure 6,
Some cooling water supply devices can switch the cooling method between water cooling and air cooling.

In the figure, 1 is a device to be cooled (printed circuit board, etc.) of a computer 2, 3 is a cooling water supply device, and 3 is a cooling water supply device.
1 is a pump, 32 is a reservoir tank, 33 is a heat exchanger, 34 is a three-way valve for bypassing cooling water when the water temperature is too cold, and 35 is a connection valve for attaching and detaching the heat exchanger portion.

Figure a shows a case where secondary cooling water is supplied to the heat exchanger 33 from the outside for water cooling. Depending on the installation conditions, secondary cooling water may not be available.

For this purpose, as shown in Figure b, the heat exchanger 33 can be removed (or bypassed) and an air cooling unit section 4 equipped with an air cooling fan 41 and a radiator 42 can be attached externally in its place. Note that the cooling air is received from the air conditioner.

Although there are such examples, the cooling water supply device 3 originally has a heat exchanger 33 for water cooling, and when the air cooling unit 4 is added, this heat exchanger 33 and the space for it are wasted. Put it away.

[Purpose of the invention]

The purpose of the present invention is to solve the above-mentioned problems, and by selecting and combining appropriate unit parts from a plurality of pre-prepared unit parts, the optimum cooling capacity can be achieved according to the required cooling capacity and the installation environment. The cooling water supply device can be configured easily and in a minimum space, and the cooling capacity and cooling method of the already installed device can be easily changed.

[Structure of the invention]

According to the present invention, the above object is to provide a device for supplying cooling water to a water-cooled device 1 to be cooled, in which a pump 52 for circulating cooling water and a heat exchange unit 6, 7, etc. are separated from each other.・Connection part 5 for connection

FIG. 3 shows a configuration change example (part 2), and FIG. a shows the same configuration as FIG. ing.

If it is desired to increase the cooling capacity, the capacity can be easily increased by replacing it with a large air cooling unit section 8 as a heat exchange unit section equipped with a large capacity heat exchanger as shown in Figure b.

If it is desired to further increase the cooling capacity, the desired cooling capacity can be achieved by connecting as many heat exchange units 9 as necessary, as shown in Figure c. The heat exchange unit section 9 is provided with a connection port connected to the connection valve 54 of the common unit section 5, as well as a connection valve 91 for connecting with other heat exchange unit sections 9, so that a plurality of heat exchangers 92 can be connected to each other.
