In the area with strong heat dissipation capability, the distance between the adjacent metal sheets 52 is increased, so that the metal sheets 52 in the electrolytic cell are arranged at unequal intervals, and the diversity of the structure of the electrolytic cell in the embodiment is improved.

With reference to fig. 11 and 12, fig. 11 is a perspective view showing a fourth structure of an electrolytic cell according to a third embodiment of the safety hydrogen absorption machine of the present invention, and fig. 12 is a sectional view showing a fourth structure of an electrolytic cell according to a third embodiment of the safety hydrogen absorption machine of the present invention. The fourth embodiment of the electrolytic cell of this example is explained as follows:

the outer ring of the metal sheet 62 in the embodiment is provided with the heat dissipation sleeve 65, and the inner wall of the heat dissipation sleeve 65 is fixedly connected with the metal sheet 62 through the heat dissipation pin 651, so that the heat dissipation efficiency of the electrolytic cell is improved.

Further, heat dissipation sleeve 65 is including being provided with a plurality ofly, splices each other between a plurality of heat dissipation sleeves 65, and a plurality of heat dissipation sleeves 65 can dismantle with sheetmetal 62 and be connected, the dismouting of being convenient for.

In addition, the side wall of the heat dissipation sleeve 65 may further be provided with heat dissipation holes 652, the structure of which is shown in fig. 13.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so that the scope of the present invention shall be determined by the scope of the appended claims.
