Abstract

PURPOSE:To permit to change the size of the casing of a heat accumulating device easily in proportional to the amount of heat accumulating body by changing the number of pieces of the arranged heat accumulating bodies by a method wherein the heat accumulating bodies are provided in the notches of a frame body having the notches at the center thereof with spaces, through which fluid can be passed. CONSTITUTION:Heat accumulating bodies 2 are provided in the notches of a frame body 1 having the notches at the center thereof with spaces 3 capable of passing fluid therethrough. The frame body 1 is formed with the notches having thicknesses capable of arranging the heat accumulating bodies 2 therein while a surface 6, capable of connecting the frame bodies mutually, is neighbored to the notches. The heat accumulating body 2 is consisting of a melting salt type heat accumulating material such as calcium chloride 6 H2O, sodium sulfate 10 H2O or the like, for example, sealed in a vessel consisting of a material having heat transfer property. The configuration of the heat accumulating body 2 may be a configuration capable of providing it in the notches of the frame body while securing spaces 3 permitting to pass fluid. The amount of the heat accumulating bodies may be increased or decreased in a heat accumulating unit for each casings in accordance with a required heat accumulating capacity.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a novel heat storage unit. Specifically, it is a heat storage unit that can configure a heat storage device having an arbitrary size by changing the number of heat storage units arranged.

[Prior Art and Problems] Conventionally, most heat storage devices incorporating heat storage bodies have heat storage bodies arranged in a casing having a supply port and a discharge port for a fluid to be treated.

On the other hand, the heat storage capacity required for heat storage devices varies depending on the field of use, the scale of the installation location, etc.

Therefore, in the heat storage device, as a means to meet the demand for heat storage capacity, the size of the casing is changed depending on the amount of heat storage required, or alternatively, a larger casing is used and a built-in A commonly used method was to adjust the amount of heat storage material.

However, changing the size of the casing does not allow mass production of the device and is extremely disadvantageous from an industrial perspective. Furthermore, using a larger casing has the problem of requiring more installation space than necessary.

[Means for Solving the Problems] The present invention has been made in view of the above problems, and by changing the number of heat storage bodies arranged, it is possible to easily change the size of the casing of the heat storage device in proportion to the amount of heat storage bodies. To provide a heat storage unit that can be changed.

The present invention will be described in detail below with reference to the accompanying drawings.
The invention is not limited to these attached drawings.

1 and 2 are perspective views showing typical embodiments of the heat storage unit of the present invention. That is, the heat storage unit of the present invention is constructed by providing a heat storage body 2 in a frame 1 having a notch in the center with a space 3 through which fluid can pass.

In the present invention, the frame 1 can form a notch thick enough to arrange the heat storage bodies 2 therein, and has a surface 6 adjacent to the notch that allows the frame to be joined to each other. There are no particular restrictions as long as it is. For example, the thickness of the frame 1 varies somewhat depending on the area of the notch, etc., but is generally 5 to 100 mm thick.
(approximately ?IIl is preferable.Although the surface 6 is generally a flat surface as shown in the figure, it can also be an uneven surface.

In the frame 1, 1. In order to arrange and fix a plurality of frames, it is a preferable embodiment to provide fixing means 4 such as bolt holes in the frame l.

In the present invention, any known heat storage body 2 may be used without particular limitation. An example of a typical heat storage body is a heat storage body in which a molten salt type heat storage material such as calcium chloride/hexahydrate or sodium sulfate/decahydrate is sealed in a container made of a thermally conductive material.

The shape of the heat storage body 2 may be any shape that can secure and provide a space 3 through which fluid can pass through the notch of the frame body 1, but from the viewpoint of ease of manufacture, a cylindrical shape or a rectangular cylindrical shape may be used. A cylindrical body or a plate-shaped body such as the above are suitable.

The manner in which the heat storage body 2 is attached to the notch is not particularly limited. For example, as shown in FIG. 2, it is integrated into the frame 1, and as shown in FIG. Examples include the manner of attachment. Among these, the latter mode is preferable because the heat storage body can be partially replaced as necessary. Further, when the heat storage body 2 uses the molten salt type heat storage material, it is preferable to arrange the nucleating agent in the horizontal direction as shown in the figure in order to prevent the nucleating agent used in combination from separating. However, in the present invention, the arrangement of the heat storage bodies is not limited to this embodiment, and the heat storage bodies may be arranged in any direction.

FIG. 21 is a sectional view showing an embodiment in which a plurality of heat storage units of the present invention shown in FIG. 1 are arranged to constitute a heat storage device. This heat storage device has units each having fluid supply/discharge ports 8, 8' and a fan 7 fixed on both sides of a stack formed by arranging heat storage units 1 by fixing means 4 provided on each unit. It is constructed.

[Effect] As understood from the above description, in the heat storage unit of the present invention, the amount of heat storage bodies can be increased or decreased for each frame serving as a casing, depending on the required heat storage capacity. Therefore, a compact heat storage device suitable for heat storage capacity can be obtained.
