Description

[Detailed explanation of the idea] The present invention relates to a refrigerated pure water cooling device.

A refrigerated pure water cooling device used for cooling an X-ray transmitting tube, etc. is equipped with a cooling circuit 1 composed of a pure water circuit 2 and a refrigerant circuit 3, as illustrated in FIG. The pure water circuit 2 includes a cooler 4 that cools pure water by absorbing heat due to evaporation of liquefied refrigerant, an ion exchange resin container 5 for maintaining pure water, a water tank 6 for storing pure water, and an X-ray transmission tube. The refrigerant circuit 3 includes a water pump 7 that circulates pure water in the circuit through an external heating element 8, and a filter 9 that removes foreign substances from the pure water, which are connected in a ring. A refrigeration compressor 10, a water-cooled condenser 11, and an expansion valve 12 that are supplied to the cooler 4 are connected in an annular manner, and the external heating element 8 is cooled with pure water cooled by a refrigerant in the cooler 4.
It consists of this.

However, when assembling the components of the cooling circuit 1 into the housing, arranging them indiscriminately increases wasted space, makes assembly work difficult, makes maintenance work difficult, and reduces the overall efficiency of the device. This causes various inconveniences such as increased size.

The present invention was developed in view of this point.The container for the ion exchange resin is built into the water tank, and the water-cooled condenser and cooler, which are coiled with double pipes above the water tank, are oriented horizontally and concentrically. By arranging them in a shape and using their internal space as a space for replacing the ion exchange resin in the water tank,
This is aimed at eliminating unnecessary space and downsizing the device.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Since the circuit configuration of the present invention is the same as that shown in FIG. 1, the reference numerals used in FIG. 1 are directly applied to the description of the present invention.

In FIG. 2, reference numeral 13 denotes a cooling device housing, and a water tank 6 and a water pump 7 are disposed on a base 13a inside the housing 13.
and a refrigeration compressor 10, respectively, and the water tank 6
Inside, a cylindrical container 5 housing a replaceable ion exchange resin 14 is built in. A flange portion 6a at the upper end of the sewage tank 6 is covered with a lid 15 that can be opened and closed with a screw. I'm wearing it.

Further, above the ice tank 6, there is a water-cooled condenser 11 formed in a small-diameter coil shape using a double pipe, and a
A cooler 4 formed into a large-diameter coil shape using heavy pipes is arranged concentrically, and the water-cooled condenser 11 and the internal space 16 of the cooler 4 are used as a space for replacing the ion exchange resin 14 in the water tank 6. I am doing it.

Furthermore, a filter 9 and an expansion valve 12 are installed inside the housing 13, and these are connected by piping as shown in FIG.

When replacing the ion exchange resin in the above-mentioned cooling device, the lid 15 is removed by removing the screws that hold the lid 15 through the water-cooled condenser 11 and the internal space 16 of the cooler 4, and the ions in the container 5 are removed. Replacement resin 1
You can take out the 4 and put in a new one.

According to the cooling device of the present invention having such a configuration, (1) Since the ion exchange resin container is built inside the water tank, there is no need for an installation space for the container in the housing.

(2) Since the water-cooled condenser and the cooler are formed into large and small coil shapes and arranged concentrically, the internal space of the coil can be effectively used and the installation space for one coil can be saved.

(3) When the water tank is full, it becomes quite heavy.
Since it is placed at the bottom, the device is stable.

(4) The water-cooled condenser and cooler are arranged concentrically above the water tank, and the internal space is used as a space for replacing the ion exchange resin in the water tank, so the above-mentioned replacement space is provided separately. There is no need to provide

(5) Since the space required for each part is shared in two or three layers, the entire device can be made very compact.

It has excellent characteristics such as.
