specific Embodiment approach 1

[0023] Specific implementation mode one: as figure 1 As shown, a heat exchange device based on a phase-change heat storage material includes a closed casing 1 for accommodating the phase-change heat storage material, and the casing surface of the casing 1 is arranged toward the inside of the casing. There is at least one inwardly concave expansion partition 2 for expansion and deformation, and the side wall or part of the side wall of the expansion partition 2 is made of a flexible film 3 . The upper side of the expansion partition 2 communicates with the atmosphere, that is, the expansion partition 2 is a depression that is added from the upper surface of the housing to the inside of the housing, and only the upper part of this depression communicates with the atmosphere, that is, from the front view ( figure 1 ) direction, the shell has a "concave" shape structure, and the lower part is connected to inject phase change heat storage material.

specific Embodiment approach 2

[0024] Specific implementation mode two: the difference between this implementation mode and specific implementation mode one is: if figure 2 As shown, the housing 1 is a closed enclosure surrounded by a bottom housing 11, a front housing 12, a rear housing 13, a left side housing 14, a right side housing 15 and an upper cover housing 16. shell; such as figure 1 As shown, the expansion partition 2 is a depression provided in the direction from the upper cover shell 16 to the bottom shell 11 . The expansion partition 2 represents that the upper cover shell 16 is divided into a space that communicates with the atmosphere, and the side wall of the expansion partition 2 extending into the shell can be inlaid in the middle by a metal plate made of the same material as the shell 1. The flexible film 3 is made, and the flexible film 3 can be a flat diaphragm or a pleated diaphragm.

specific Embodiment approach 3

[0025] Specific embodiment three: the difference between this embodiment and specific embodiment two is that a dustproof sealing cover 21 is provided above the expansion partition 2, and the dustproof sealing cover 21 and the upper cover shell 16 are in the same level.

Abstract

The invention relates to the technical field of intermittent heating, in particular to a heat exchanging device based on phase-change heat storage material and a packaging method of the heat exchanging device. The purpose is to solve the problem that a shell of the heat exchanging device is expanded and damaged due to volume expansion of the phase-change heat storage material in the phase change process. The device comprises a closed shell used for containing the phase-change heat storage material, at least one expansion partitioning part which dents inwards and is used for expansion deformation is arranged in the direction from the surface of the shell to the inside of the shell, and all or part of the side walls of the expansion partitioning part are made of soft films. The packaging method mainly includes the steps that a hole plug of a vent hole in the shell is pulled out, so that a communication device is formed in the shell partitioned by the expansion partitioning part; a funnel is erected on a feed port, a discharge port is sealed, the phase-change material in a liquid state is injected from the funnel, after the shell is full, the hole plug is plugged, and the feed port is sealed to complete packaging. The heat exchanging device has the advantages of being high in heat storage and conduction efficiency, convenient to package, capable of being used repeatedly, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of intermittent heating, and is mainly used in intermittent heating methods such as flue walls or kangs, and in particular relates to a heat exchange device based on a phase-change heat storage material and a packaging method thereof. Background technique [0002] Firewall and heated kang are one of the earliest intermittent heating technologies that have been mastered and used in severe cold areas in my country. They are the crystallization of wisdom of working people who have lived in severe cold climate conditions for a long time. They are still commonly used in rural buildings in severe cold areas. Heating methods. In recent years, scholars at home and abroad generally believe that ancient heating methods such as flue walls and heated kangs are in line with the concept of sustainable development, and can solve the heating problem of scattered residents with low cost and renewable energy (crop straw) consu...
