Description

[Detailed description of the invention] The purpose of this invention is to provide a cooler that can efficiently cool water to a desired low temperature. Moreover, it can be cooled to a uniform temperature, and the manufacturing cost is low.

An example of implementing the present invention will be described below based on the drawings.

Fig. 1 is a cutaway view in the vertical direction, Fig. 2 is a cutaway view in the horizontal direction, and Fig. 3 is a cross-sectional view taken along the line X-X of Fig. 1. In each figure, 1 indicates the cylinder. It is a container main body having a shape, and is installed horizontally on a pedestal 3 integrated with left and right side wall plates 2 a and 2 b.

Reference numeral 4 denotes an introduction pipe for water to be cooled, and the pipe opening opens in the circumferential direction of the inner peripheral wall surface of the cylinder near the side wall plate 2a.

Reference numeral 5 denotes a coiled refrigerant pipe, and the population 5a and outlet 5 are connected to the wall plate 2b on the opposite side where the introduction pipe of the water to be cooled is provided.
b is provided, and refrigerant flows in from a refrigerator (not shown) housed on the lower surface of the pedestal 3.

At this time, the refrigerant pipe 5 is arranged so that its coiled pipe wall portion follows the inner circumferential wall surface of the cylindrical container body 1, and the refrigerant flowing from the tube 5a and proceeding inside the pipe is discharged from the introduction pipe. This forms a countercurrent state with the water to be cooled flowing while swirling inside the container body 1.

Reference numeral 6 denotes a cooling water discharge port, which is bored in the center of the side wall plate 2b, and a cooling water discharge pipe 8 is led to the outside and upward of the container body 1 via a curved pipe 7, and is an iron pipe. The predetermined length of the container is made to extend approximately parallel to the upper part of the exterior of the container body.

On the other hand, a through hole 9 is bored in the upper center ceiling wall of the container body 1, and communicates with the discharge pipe 8 extending along the upper exterior of the container body 1 via a communication pipe 10.

On the other hand, numeral 11 is a hot water detector inserted into the center of the container body 1 from the side wall plate 2a side.

Next, the effect will be explained.

Although not shown, a pump is provided inside the bottom surface of the pedestal 3.
Water from a fish tank or the like that requires cooling is appropriately pumped up using a hose or the like, and is discharged into the container body 1 through the introduction pipe 4.

At this time, since the opening of the inlet pipe 4 opens in the circumferential direction of the cylindrical container body, the discharged water to be cooled becomes a laminar flow and flows toward the outlet 6. When it comes into contact with the coiled refrigerant pipe 5, cooling is performed.

Therefore, the cooling water is returned to the fish tank etc. from the discharge port 6 through the discharge pipe 8, but in the present invention, the discharge pipe 8
A certain length of the air is guided upward to the outside of the cylindrical container body 1 and communicated with the through hole 9 formed in the ceiling wall of the container body 1. This means that the residual air inside the container body 1 is It has the effect of suctioning and removing the water while passing through, and causes the water to be cooled in the container body 1 to swirl and flow vigorously, so that efficient cooling can be performed.

In addition, in the present invention, it is possible to increase the contact with the refrigerant without providing a stirring means, etc., and it is possible to cool a large amount of water with a relatively small volume, and the unit manufacturing cost is low. It is.

It is particularly suitable for use in fish preserves that require a large amount of seawater to be stably maintained at a desired low constant temperature, and to prevent rust when using seawater, the refrigerant pipes are coated with a vinyl chloride resin film. In addition, vinyl chloride pipes are used for inlet pipes, drainage pipes, etc.
