Example Embodiment

[0032] Such as figure 1 Shown is a heat storage device 8 of the present invention. It includes a shell 1, a solid heat storage material filled in the shell 1 and a heater (not shown in the figure). An air duct 2 is provided in the thermal material. The air duct 2 is a straight air duct. The air duct 2 penetrates the shell 1 and forms an air inlet and an air outlet on the opposite side walls of the shell 1. The shell where the air inlet and the air outlet are located The wall surface of the body 1 is a mesh surface 3, and the mesh diameter of the mesh surface 3 is 2 cm. In this embodiment, the heater is fixed on the inner wall surface of the casing 1, that is, the inner wall surface can be the top surface, left and right sides of the casing 1. The heater is located on the periphery of the air duct 2 and is in the solid heat storage material. Contact with it.

[0033] The solid heat storage material is filled in the shell according to the following heat storage material filling me...

Abstract

The invention discloses a heat storage material filling method capable of improving the sensible heat storage density of a solid and a heat storage device. The heat storage material filling method comprises the following steps that a small-particle solid heat storage material is laid at the bottom of a housing; a medium-particle solid heat storage material is laid on the small-particle solid heatstorage material; a large-particle solid heat storage material is laid on the medium-particle solid heat storage material; the medium-particle solid heat storage material is laid on the large-particlesolid heat storage material, and the small-particle solid heat storage material is laid on the medium-particle solid heat storage material; and the small-particle solid heat storage material is laidcontinuously, the medium-particle solid heat storage material is laid on the small-particle solid heat storage material, and the large-particle solid heat storage material is laid on the medium-particle solid heat storage material. The solid heat storage material is divided according to the particle size of the solid heat storage material to perform layered filling, and does not need being subjected to press-fit, the void ratio of the solid heat storage material can be reduced to the maximum extent, the solid sensible heat storage density is improved, and the heat storage efficiency is furtherimproved.

Description

technical field [0001] The invention relates to a heat storage material filling method for increasing solid sensible heat storage density, and also relates to a heat storage device using the heat storage material filling method. Background technique [0002] Sensible heat storage is the heat absorbed or released when the temperature of the substance rises or falls, while the nature of the substance itself does not change. Sensible heat storage materials are divided into liquid and solid. Commonly used high-temperature solid sensible heat storage materials are gravel, sand, brick, ceramics, glass, iron, aluminum, concrete, ore, and magnesia bricks. [0003] For high temperature solid sensible substances, the heat transfer medium or the medium used to absorb thermal energy or absorb heat from an external source is a fluid substance. The heat transfer fluid can be water, air, any hydrocarbon fluid (such as thermal oil), molten salts (such as sodium nitrate, potassium nitrate, ...
