The first structure  215  is combined with the casing structure  214  to form the water supplement space for accommodating the fan  42 . The first structure  215 , the casing structure  214 , and the water input tube  212  can be the combined structure to connect the accommodation space  23 , the water supplement space  211 , and the water input port  112 . In another embodiment, the first structure  215 , the casing structure  214 , and the water input tube  212  can be integrally formed. The actuator  41  is disposed outside of the casing structure and is corresponded to the fan  42 . The actuator  41  can use the magnetic coupling to drive the fan  42  to rotate. Therefore, the electrolyzed water in the accommodation space  23  is guided into the water input port  112 . 
     Furthermore, the tank body  21  of the water tank  2  further comprises the water input tube  212  to connect with the water supplement space  211 . Wherein, the water supplement space  211  is connected with accommodation space  23 . The water input tube  212  is connected with the water input port  112 . When the fan  42  rotates in the water input tube  211 , the electrolyzed water in the accommodation space  23  is drived by the fan  42  into the water supplement space  211 . The fan  42  inputs the electrolyzed water from the water supplement space  211  to the water input tube  212  and enters into the radiator  1  through the water input port  112 . 
     Please refer to  FIG. 7 .  FIG. 7  is an explode diagram illustrating the radiator and hydrogen generator E with heat dissipation function according to an embodiment of the upper cover of the present invention. As shown in  FIG. 7 , in one embodiment, the side of the adjacent accommodation space  23  of the upper cover  22  of the water tank  2  comprises the plurality of fixing units  2211  to staggeredly form the fixing structure  221 . The water tank  2  comprises the cover plat and the fixing structure  221 . This fixing structure  221  is used to strengthen the structure of the upper cover  22  to support the radiator  1  and is made of the corrugated paper. In practical applications, when the electrolytic cell  3  electrolyzes the electrolyzed water in the water tank  2  to generate the hydrogen comprising gas in the accommodation space  23 , the fixing structure  221  of the upper cover  22  thickens the volume of the upper cover  22 . Although the part of the accommodation space  23  is reduced, the time of the hydrogen comprising gas in the accommodation space  23  is shortened and the amount of gas is reduced in the accommodation space  23  due to the space constraint. The cover plate  24  is used to reduce the hydrogen comprising gas remaining in the staggered fixing unit  2211 . Wherein, the above-mentioned electrolytic cell  3  can be disposed in the accommodation space  23  directly. Also, the additional tube can be added to connect with the accommodation space  23  to output the electrolyzed water to the electrolytic cell  3  and to input the hydrogen comprising gas and the high-temperature electrolyzed water into the accommodation space  23 , which is not limited to this. 
     Please refer to  FIG. 8  to  FIG. 10 .  FIG. 8  is an explode diagram illustrating the radiator and hydrogen generator E with heat dissipation function according to an embodiment of the electrolytic cell of the present invention.  FIG. 9  is a base view illustrating the radiator and hydrogen generator with heat dissipation function according to an embodiment of the electrolytic cell fix sheet  32  of the present invention.  FIG. 10  is an inside schematic diagram illustrating the radiator and hydrogen generator with heat dissipation function according to an embodiment of the tank body  21  and the water pump  4  of the present invention. As shown in  FIG. 8 , in one embodiment, the electrolytic cell  3  comprises the electrode element  31  and the electrolytic cell fix sheet  32 . The electrode element  31  can be disposed in the electrolytic cell body  321  of the electrolytic cell fixing plate  32 . The electrode element  31  comprises the plurality of electrode sheet  311  and is connected to each electrode sheet  311  of the base plate  31 . The base plate  312  is disposed on the upper surface of each electrode sheet  311 . Therefore, the plurality of the electrode plates  311  can be respectively disposed. The electrode element  31  can form the plurality of the electrode flows when it is accommodated in the electrolytic cell body  321 . As shown in  FIG. 8  to  FIG. 10 , in another embodiment, the electrolytic cell fixing sheet  32  comprises the electrolytic cell body  321  and a separating sheet  322 . The separating sheet  322  can be used to fix the electrolytic cell  3  in the water tank  2  and divide the water tank  2  into upper and lower layers. Therefore, the electrolyzed water is mainly disposed in the lower layer, and the hydrogen comprising gas is mainly disposed in the upper layer produced by electrolysis water. In order to keep the upper and lower layers in circulation. The separating sheet  322  comprises the plurality of water circulation holes  3221  to connect the upper layer and the lower layer. As shown in  FIG. 9 , the bottom side of the electrolytic cell body  321  comprises the plurality of water circulation holes  3211 , so that the electrolyzed water can flow into each electrode channel through the water circulation hole  3211 , and each electrode sheet  311  can be electrolyzed to generate the hydrogen comprising gas. In addition, the base plate  312  comprises the plurality of gas circulation holes  3121 , so that the hydrogen comprising gas which is generated by electrolysis from the gas circulation hole  3121  flows to the water tank  2 . The electrolytic cell fix sheet  32  can be integrally formed. In addition, it can be understood that those skilled in the art can design the shape of the separating sheet  322  according to requirements, and it is configured to provide the space for other components. 
     Please refer to  FIG. 5A  and  FIG. 6B . The water input tube  212  is shorter than the water output duct  114 . The water output duct  114  is disposed in lower layer of the water tank  2 . Therefore, when the radiator  1  is worked, the radiator inputs the electrolyzed water which dissipates heat into the lower layer through the water output duct  114 , and the radiator  1  receives the electrolyzed water from the upper layer. Therefore, the temperature of the electrolyzed water is reduced by circulating in the water tank  2 . 
     Compared to the prior art, the radiator of the present invention has the following advantages: 1. The radiator of the present invention uses the spiral structure and the delay structure to increase the path length in the column structure with limited space; therefore, the heat dissipation efficiency of the radiator is improved by increasing the contact area between the electrolyzed water and the external environment. 2. The radiator of the present invention does not increase extra columns and extra installation space, so that the hydrogen generator can be downsized. 3. The radiator of the present invention combines the bottom and the column to form a heat dissipation channel; therefore, only the damaged column needs to be disassembled and replaced when the column get damaged. Since there is no need to replace the entire radiator, the subsequent maintenance costs can be reduced. 4. The base of the radiator of the present invention is directly and integrally formed with the upper cover of the water tank of the hydrogen generator, and the assembly can be completed only by coupling the column to the base, thereby reducing the assembly process.

More importantly, the present invention is not limited to the embodiment described herein. Those skilled in the art will readily observe that numerous modifications and alterations of the device may be made while retaining the teachings of the invention.
