上を図ることができる。 First, in the heat storage cycle, the cooling device is operated using surplus energy such as at night, and the cooling liquid 3 in the intermediate tank B is cooled while being circulated through the cooling pipe line 14. As a result, the freezing tube 1 and the horizontal plates 8 and 9 are cooled, and the inner circumference of the freezing tube 1, the upper surface of the horizontal plate 8, and the horizontal plate 9 are cooled.
The liquid to be cooled 2 is cooled and frozen on the lower surface,
It becomes ice 2a. The ice 2a gradually increases in thickness and accumulates cold heat. The thickness of the ice 2a is controlled by means not shown so as not to exceed a predetermined value, thereby preventing the inside of the freezing tube 1 from being blocked by the ice 2a. This is the state shown in FIG. 5a. At this time, the liquid to be cooled 2 is transferred from the upper tank A to the freezing tube 1.
The liquid to be cooled 2 may be frozen at the above position while being circulated through the inner tank to the lower tank C.
By freezing on the inner surface of the freezing tube 1, etc. in a stationary state, it is possible to improve the freezing efficiency by shortening the freezing time.

においても被冷却液２を氷結させるため、被冷却
液２への冷熱蓄積の効率は高い。 In this embodiment, in addition to the inside of the freezing tube 1, the horizontal plates 8 and 9 are
Also, since the liquid 2 to be cooled is frozen, the efficiency of accumulating cold heat in the liquid 2 to be cooled is high.

に至る。 The heat dissipation cycle is performed during times when cooling and heat are used, such as during the daytime. That is, by operating the pump P, the liquid to be cooled 2 is circulated from the lower tank C through the cold load 4, the upper tank A, and the freezing tube 1 in this order. The liquid to be cooled 2 in the upper tank A flows down into the freezing tube 1 from the notch 11 at the upper end of the freezing tube 1 . The notch 11 is the freezing tube 1
Since they are formed at equal intervals in the circumferential direction of the upper end, the liquid to be cooled 2 flows down to the inner circumference of the freezing tube 1 almost uniformly in the circumferential direction. The liquid to be cooled 2 flowing down into the freezing tube 1 flows from the lower end notch 13 of the freezing tube 1 to the lower tank C.

る。 The liquid 2 to be cooled from such an upper tank A to a lower tank C
In this flow, the liquid 2 to be cooled is cooled by coming into contact with the ice 2a and melting it while absorbing cold heat. The cooled liquid 2 enters the circulation pipe 15 from the lower tank C and reaches the cold load 4, where it is heat exchanged and loses its cold energy. The cold heat is supplied to a cooling device (not shown) through a pipe 19. The liquid 2 to be cooled, which has lost its cold energy due to the cold load 4, is supplied as it is to the upper tank A, is cooled again by the cold energy of the ice 2a, becomes cold, and repeats the above operation. This situation is shown in FIG. 5b.

イクルにおける被冷却液２の冷却効果は高い。 Through this heat dissipation cycle, the cold heat accumulated in the liquid to be cooled 2 in the heat storage cycle is released, and the frozen liquid to be cooled 2 is melted. and,
When the ice 2a of the frozen liquid 2 to be cooled melts, the liquid 2 to be cooled is also cooled by its latent heat, so that the cooling effect of the liquid 2 to be cooled in the heat dissipation cycle is high.

becomes unnecessary. Furthermore, it goes without saying that the legs 12 may be constructed from a separate member from the freezing tube 1.

It is piped to. Other configurations and operations are the same as in the first embodiment.

A stirring blade 17 is placed at the intersection of the passages 22 and 24.
is facing, and this stirs the cooling liquid 3 in the middle tank B. The stirred cooling liquid 3 passes between the freezing tubes 1 from the stirring blade 17 via the passage 22, cools the liquid 2 to be cooled here, reaches the passage 23, and from there passes through the passage 24 to the stirring blade. Cycles to 17. This is the flow of the coolant 3 shown by the arrow in FIG. 25 is a current plate. Note that in FIG. 9, some of the freezing tubes 1 are not shown. Other configurations and operations are the same as in the first embodiment.

ある。 In FIG. 10, an auxiliary pipe 6 having a cross-sectional structure is stretched between the horizontal plates 8 and 9, and this connects the upper tank A and the lower tank C, so that the freezing pipe 1 is frozen and the ice 2a is formed. Even when the tank is blocked, the liquid 2 to be cooled is allowed to flow from the upper tank A to the lower tank C. This auxiliary pipe 6
has a heat insulating structure with a double structure, but it goes without saying that other structures may be used to provide the heat insulating function. Note that the upper end of the auxiliary tube 6 protrudes above the horizontal plate 8 and is located at a higher position than the upper end of the freezing tube 1.

によれば、氷結管１内が氷２ａによつて閉塞され
ることを防止する手段を設ける必要はなくなる。 With this configuration, even in a heat dissipation cycle when the inside of the freezing tube 1 is blocked, the cooled liquid 2 that overflows into the upper tank A initially flows through the auxiliary pipe 6, and the cooled liquid 2 that is circulated to the upper tank A flows through the auxiliary pipe 6. As the cold heat is transferred to the liquid 2, the ice 2a in the freezing tube 1 gradually melts, and the liquid 2 to be cooled flows through the freezing tube 1 from the upper tank A to the lower tank C.
It starts to flow down towards. Therefore, according to this embodiment, there is no need to provide a means for preventing the inside of the freezing tube 1 from being blocked by ice 2a.

As explained above, according to the present invention, an upper tank, a middle tank, and a lower tank are provided, and the upper tank and the lower tank are connected by a freezing pipe passing through the middle tank to form a passage for the liquid to be cooled. At night, the coolant that is cooled by electric power or the like and filled in the inner tank freezes at least a part of the cooled liquid inside the freezing tube, accumulating cold heat in the cooled liquid, while during the daytime, etc. , the cold heat is released from the frozen part of the liquid to be cooled and the cold heat is supplied to the cold load such as an air conditioner. Thus, this invention
Since a large number of freezing tubes are arranged in the tank and the outer periphery of the tubes is filled with cooling liquid, a sufficient amount of cold energy is accumulated in the liquid to be cooled in the freezing tubes and other parts that contact the inner tank. Moreover, since the freezing tube itself can be manufactured by cutting a fluid transfer tube, it also has the effect of contributing to cost reduction. Furthermore, according to the present invention, since the liquid to be cooled is frozen to accumulate cold heat, during the heat dissipation, latent heat contributes in addition to the cold heat of the ice, so that the liquid to be cooled is sufficiently cooled in the heat dissipation cycle. As a result, there is an effect that the cold heat is sufficiently transferred to the equipment that uses the cold heat.
