Heat conduction fin and solid state hydrogen storage device having same
Disclosed is a solid state hydrogen storage device, capable of providing a weight reduction of a hydrogen storage system while inhibiting heat conduction performance from being degraded, and also of increasing hydrogen storage capacity. The present disclosure provides a heat conduction fin including multiple tube passing holes through which the heat exchange tube passes and linear-shaped connecting portions connecting the tube passing holes to each other, and a solid state hydrogen storage device having the same.
1. A heat conduction fin of a solid state hydrogen storage device having heat exchange tubes, the heat conduction fin comprising:
multiple tube passing holes through which the heat exchange tubes are configured to pass; and
multiple connecting portions connecting the multiple tube passing holes to each other,
wherein the multiple connecting portions include:
first connecting portions each having a straight shape, and
second connecting portions each having a curved shape, and
wherein the multiple tube passing holes are provided at the same radial position with respect to a center of the heat conduction fin and the second connecting portions are configured to connect the multiple tube passing holes to each other along a circumferential direction of the heat conduction fin.
2. The heat conduction fin of claim 1 , wherein the multiple connecting portions that connect the tube passing holes to each other form closed spaces defined between adjacent connecting portions.
3. The heat conduction fin of claim 2 , wherein the heat conduction fin is disposed between hydrogen storage materials; and
the hydrogen storage materials are provided in the closed spaces.
4. The heat conduction fin of claim 1 , wherein ends of the multiple connecting portions are integrally secured to outer circumferential edges of the tube passing holes.
5. The heat conduction fin of claim 1 , wherein among the multiple connecting portions, one connecting portion and another connecting portion intersect each other so as to be integrally secured to each other.
6. The heat conduction fin of claim 1 , wherein the multiple tube passing holes and the multiple connecting portions are provided on a common horizontal plane.
7. The heat conduction fin of claim 6 , wherein a material of the heat conducting fin forming the multiple tube passing holes has a thickness equal to a thickness of the material forming the multiple connecting portions.
8. The heat conduction fin of claim 1 , further comprising:
a connecting ring portion having an annular shape provided at an edge of the heat conduction fin, wherein
the first connecting portions are connected to an inner circumferential surface of the connecting ring portion.
9. The heat conduction fin of claim 1 , further comprising:
a hydrogen injection portion provided at a center of the heat conduction fin,
wherein the first connecting portions are connected to an outer circumferential surface of the hydrogen injection portion.
