JPS59104092A - Regenerative capsule - Google Patents

Abstract

PURPOSE:To prevent a regenerative capsule from being broken caused by the change in volume of a capsule being accompanied with melting or solidification of regenerative medium, as well as to increase the heat exchanging efficiency of a heating medium with a substance to be heat-exchanged in the regenerative capsule, by constituting the capsule of a flexible bellows. CONSTITUTION:A capsule is constituted of a metallic material or a high polymeric material such as coper, stainless, or resin, rubber, silicon or silicon rubber, for example, or a mixture of some of them, being mixed with metallic powder and metallic fiber. The capsule is a bellows being formed by continuing a number of tilted pieces 1 in the lengthwise direction. When the heating medium in the capsule exchanges heat with a substance 2 to be heat-exchanged, that is heated water, for example, the volume of regenerative medium is gradually increased and the pressure is produced in the capsule. But the capsule can stretch mainly to the directions as shown by arrow signs in accordance with the increase in volume, and the inner volume of a capsule is increased, because it has flexibility, so that it can be prevented from being broken.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat storage container that stores heat by utilizing the latent heat of a built-in heat storage medium, and its purpose is to improve the heat exchange performance between the heat medium and the heat exchange material in the heat storage container. The objective is to prevent damage to the container due to volume changes due to melting or solidification of the heat storage medium.

Latent heat storage media (with the exception of water) generally increase in volume when changing from solid to liquid. Therefore, when a container is filled with a solid heat storage medium, the body 51 increases due to melting, and a large internal pressure is applied to the container, making it easy to break.

Conventionally, as a countermeasure against this problem, a part of the heat storage container is made hollow, and the melted medium is allowed to flow into the hollow, thereby preventing the container from being destroyed due to an increase in the volume of the medium.

However, with the above method, if the solution is melted from the opposite side of the cavity, the solids in the middle will prevent the solution from flowing into the cavity, and as the volume increases, local pressure will be applied to the container. It could get damaged.

In addition, since a general container is cylindrical, the heat exchange area is small and the amount of heat storage is relatively small.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the container is constructed of a bellows body that can be expanded and contracted.

Embodiments of the present invention will be described below with reference to the drawings. This container is made of a metal material, a polymer material, such as copper, stainless steel, resin, rubber, silicone, silicone rubber, etc., or a mixture of these with metal powder and metal fiber. Formed from old and new years,
The shape is a bellows shape in which a large number of inclined pieces 1 are continuous in the vertical direction.

A large number of such containers (two are shown in the illustration) are immersed in the heat exchange material 2, and if the heat medium (not shown) filled inside is solid, such as Nono Rough In, the container is immersed in the heat exchange material 2. It has a shape.

In an embodiment having such a configuration, the heat medium in the container undergoes heat exchange. When heat is exchanged with, for example, hot water, the volume of the heat storage medium gradually increases and pressure is generated in the container. However, since the container has elasticity, as the volume increases, the container mainly stretches in the direction of the arrow to increase the internal volume of the container and prevent breakage. Note that the container whose shape has changed is indicated by a chain line.

The trench container is bellows-shaped and has a large heat exchange area, so it has good heat exchange performance, making it an excellent heat storage container.
