Title:
HEAT STORAGE DEVICE AND MANUFACTURING METHOD FOR HEAT STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2022089091
Kind Code:
A
Abstract:
To provide a heat storage device advantageous in terms of stability of supercooling of a latent heat storage material.SOLUTION: A heat storage device 1 comprises a shell 5 comprising an internal space including a first space 2, a second space 3, and a third space 4. A latent heat storage material 6 is housed in the third space 4. A heat transfer pipe 7 comprises an outer surface 70 in contact with the third space 4, and causes the first space 2 and the second space 3 to communicate with each other. A first header member 8 separates the first space 2 from the third space 4. A first joint material 10 exists in at least a first joint part 84 between the first header member 8 and the outer surface 70 of the heat transfer pipe 7. An area of the first joint material 10 in contact with the first space 2 is larger than an area of the first joint material 10 in contact with the third space 4. The heat transfer pipe 7 and the first header member 8 include aluminum or an aluminum alloy as a main material.SELECTED DRAWING: Figure 1
