specific Embodiment approach 1

[0024] 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 1 is provided with at least one expander for expansion deformation. Partition 2. The setting of the expansion partition 2 is mainly used for the volume change of the phase change heat storage material stored in the shell during the phase change process, and transfers its pressure deformation to the shell 1 to the expansion partition 2 .

specific Embodiment approach 2

[0025] 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; the front shell 12 is provided with a plurality of slots I 121 for clamping the expansion partition 2 on the side close to the inside of the shell 1, and the rear shell 13 is close to the shell 1 One side of the interior is provided with a plurality of locking slots II 131 for locking the expansion partition 2 , and the locking slots I 121 and the locking slots II 131 are arranged opposite to each other. The relative arrangement of the slot I 121 and the slot II 131 can ensure that the expansion partition 2 can be inserted into the casing 1 in parallel, and divide the casing 1 into a plurality of parallel and connected accommodation s...

specific Embodiment approach 3

[0026] Specific implementation mode three: the difference between this implementation mode and specific implementation mode two is: if Figure 4 to Figure 6 As shown, the expansion partition 2 includes a cylinder I21 snap-fitting with the slot I121, a cylinder II22 snap-fitting with the slot II131, and connecting the cylinder I21 and the cylinder II22. The expansion partition body 23 is provided with at least one communication hole 24 on the expansion partition body 23 . The cylinder I21 and the cylinder II22 can be made of hollow plastic, which are used to clamp and support the entire expansion partition 2, and a metal skeleton 233 can be arranged between the cylinder I21 and the cylinder II22 for connection. It is used to fix the flexible film 231 to make the connection between the flexible film 231 and the column more secure. The expansion partition 2 divides the shell 1 into a plurality of accommodation spaces arranged in parallel, and the arrangement of the communication...

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, and at least one expansion partitioning part used for expansion deformation is arranged in the shell. The packaging method mainly includes the steps that an upper cover face shell body of the shell is opened, and the expansion partitioning part is inserted in the shell and fixed; the upper cover face shell body is sealed after covering, and then a hole plug of a vent hole is pulled out, so that a communication device is formed in the shell partitioned by the expansion partitioning part through a communication hole formed in 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...
