Description

Technical Field

[0001] The utility model relates to the technical field of heat storage devices, in particular to a magnesium alloy phase change material heat storage device. Background Art

[0002] Phase change heat storage material is a material with variable temperature energy storage characteristics. Phase change heat storage material uses its special physical properties to stabilize the temperature within a smaller temperature range during phase change, thereby realizing heat storage and extraction. Its heat storage principle is mainly to use the latent heat absorbed or released by the substance during the phase change process to realize heat storage and release. The phase change process can be used to store or release energy, which is called phase change heat. When the physical state changes, the material can absorb heat from the environment, and vice versa. This energy storage method is carried out under a very narrow temperature range, so that the temperature of the material itself remains almost unchanged before the phase change is completed. When a large amount of phase change heat is transferred to the environment, a wide temperature platform is generated, which reflects the extension of the constant temperature time.

[0003] When magnesium alloy phase change materials are used to store heat under the prior art, the heat needs to be stored in a container. During the opening and closing process of the container, the container may leak heat due to loose sealing. Therefore, a magnesium alloy phase change material heat storage device is proposed to solve the above-mentioned problem. Utility Model Content

[0007] Preferably, the extrusion assembly further includes a limiting rod, the number of the limiting rods is two, and the two limiting rods are respectively arranged on the left and right sides of the first screw.
