Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a cooling device useful for, for example, cooling an electric cable installed in a trough, thereby cooling a refrigerant whose temperature has increased.

(Technical background of the invention and its problems) Generally, the power cable installed in the trough is indirectly cooled by cooling pipes arranged in parallel at the upper part of the trough.

When a refrigerant such as water passing through the cooling pipe passes through a cooled part such as an electric cable, the temperature rises to about 25° C., and the heated refrigerant is stored in a heat storage tank.

The refrigerant stored in the heat storage tank is cooled to a desired temperature by a cooler under the control of a temperature detection device installed in the heat storage tank, and then sent out again to a cooled part such as an electric cable.

However, in the cooling method using such a refrigerant, approximately 2
There was a problem in that if the high temperature refrigerant heated to about 5 degrees Celsius was sent directly into the cooler, the cooler would be destroyed.

(Purpose of the invention) The present invention has been made based on the above-mentioned circumstances, and aims to provide a cooling device that does not send high-temperature refrigerant directly to the cooler.

(Summary of the invention) The cooling device according to the invention is divided into at least three chambers by at least two partition walls, a low-temperature refrigerant is stored in one of the divided chambers, a high-temperature refrigerant is stored in the other chamber, and A heat storage tank in which an intermediate refrigerant is stored in each intermediate chamber, and the low-temperature refrigerant is caused to overflow from one side chamber to the other side chamber over the above-mentioned partition walls, and a chamber on the other side of this heat storage tank. a cooler that cools the high-temperature refrigerant and sends the cooled low-temperature refrigerant to a chamber on one side of the heat storage tank; a delivery pipe that sends the low-temperature refrigerant from the chamber on one side of the heat storage tank to the cooled part; A discharge pipe that stores the heated refrigerant discharged from the delivery pipe and heated through the cooled part in the middle chamber of the heat storage tank, and a space between the other side chamber of the heat storage tank and the middle chamber. A communication pipe is provided that penetrates the existing partition wall and is arranged so as to communicate the two chambers, and the tip of the discharge pipe is introduced into the end of the communication pipe located in the intermediate chamber. It is characterized by the presence of

(Example of idea) Hereinafter, the present invention will be explained based on the drawings of one embodiment.

As shown in FIG. 1, the cooling device according to the present invention is divided into at least three chambers 1 to 10 by at least two partition walls 11 to 19.
A low-temperature refrigerant is stored in the chambers 1 to 3 on the other side, an intermediate refrigerant is stored in the intermediate chambers 4 to 9, and the low-temperature refrigerant is supplied from the chamber 10 on one side across the partition walls 11 to 19 to the other side. The heat storage tank 20 is made to overflow into the chamber 1 of the heat storage tank 20, and the high-temperature refrigerant in the chamber 1 on the other side of the heat storage tank is cooled, and the cooled low-temperature refrigerant is sent to the chamber 10 on the one side of the heat storage tank 20. Cooler 2
1, a delivery pipe 22 that sends the low-temperature refrigerant from the chamber 10 on one side of the heat storage tank 20 to the parts to be cooled, and a heating refrigerant discharged from the delivery pipe and heated through the part to be cooled to the heat storage tank. 2
It penetrates the partition wall 15.17 existing between the discharge piping 23 storing the storage in the intermediate chamber 0, for example 6, and the chamber 3 on the other side of the heat storage tank 20, for example, and the intermediate chamber 6, so as to communicate the two chambers. It is mainly composed of a communication pipe 24 arranged in the.

As shown in FIG. The refrigerant is mixed with the refrigerant, and the mixed refrigerant passes through the communication pipe 24 and is introduced into the high-temperature refrigerant stored in the chambers 1 to 3 on the other side.

In order to sufficiently mix the heated refrigerant and intermediate refrigerant,
It is desirable to arrange the communication pipe 24 at the bottom of the heat storage tank 20.

In addition, in the figure, P indicates a pump, 25 and 26 indicate piping, and 27 indicates a refrigerant.

(Effect of the invention) In the invention described above, the tip of the discharge pipe is placed in the middle chamber of the heat storage tank, and the mixed refrigerant of the heated refrigerant and the intermediate refrigerant is mixed into the high-temperature refrigerant through the communication pipe. , there is no need to send high-temperature refrigerant directly to the cooler as in the past.

Therefore, the present invention can provide a cooling device that does not destroy the cooler.
