Description

Technical Field

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. As an important form of hydrogen energy utilization, it has the characteristics of being pollution-free, low-noise and highly efficient. The basic principle of a hydrogen fuel cell is the reverse reaction of water electrolysis, providing hydrogen and oxygen to the anode and cathode respectively. Hydrogen is decomposed into electrons and hydrogen ions (protons) through the catalyst (platinum) in the positive electrode of the fuel cell. The protons reach the negative electrode through the proton exchange membrane and react with oxygen to form water and heat. The corresponding electrons flow from the positive electrode through an external circuit to the negative electrode to generate electricity. Since heat is generated during the reaction, the hydrogen fuel cell needs to be cooled and dissipated.

[0025] Example 2

[0026] See also Figure 1 、 Figure 2 and Figure 6 The hydrogen fuel cell-based cooling system of this embodiment adds a control unit on the basis of the first embodiment. The control unit includes a temperature sensing probe 18 and a controller 19. The temperature sensing probe 18 is fixedly mounted on the inner side of the cooling box 1, and the output end of the temperature sensing probe 18 is signal-connected to the input end of the controller 19. The output end of the controller 19 is electrically connected to the input ends of the heat dissipation motor 72 and the liquid supply pump 14, respectively. The controller 19 includes a signal receiving module 191, a value setting module 192, a signal processing module 193, and a circuit control module 194. The input end of the signal receiving module 191 is signal-connected to the output end of the temperature sensing probe 18. The output ends of the signal receiving module 191 and the value setting module 192 are both signal-connected to the input end of the signal processing module 193. The output end of the signal processing module 193 is signal-connected to the input end of the circuit control module 194. The output end of the circuit control module 194 is electrically connected to the input ends of the heat dissipation motor 72 and the liquid supply pump 14, respectively. In this embodiment, the temperature range of the hydrogen fuel cell body 3 is set by operating the buttons on the surface of the controller 19 and using the value setting module 192. When the hydrogen fuel cell body 3 is in operation, the temperature sensing probe 18 will detect the temperature inside the cooling box 1 in real time, and transmit the detected temperature value information to the signal receiving module 191 in the form of a signal, and the signal receiving module 191 will transmit the received signal to the signal processing module 193. At this time, the signal processing module 193 will amplify the signal. If the temperature value detected by the temperature sensing probe 18 is greater than When the temperature value range is set by the numerical setting module 192, the circuit control module 194 will connect the circuits of the heat dissipation motor 72 and the liquid supply pump 14, so that the heat dissipation motor 72 and the liquid supply pump 14 will run due to power-on and dissipate heat for the hydrogen fuel cell body 3 inside the cooling box 1. If the temperature value detected by the temperature sensing probe 18 is lower than the temperature value range set by the numerical setting module 192, the circuit control module 194 will disconnect the circuits of the heat dissipation motor 72 and the liquid supply pump 14, so that the heat dissipation motor 72 and the liquid supply pump 14 will stop running due to power failure, thereby reflecting the intelligence of the cooling system.

[0027] In summary, the hydrogen fuel cell-based cooling system of this embodiment, by setting a temperature sensing probe 18 and a controller 19, can facilitate real-time monitoring of the temperature environment inside the cooling box 1 during the use of the hydrogen fuel cell. When the temperature is high, it can timely control the operation of the heat dissipation motor 72 and the liquid supply pump 14, and perform heat dissipation and cooling treatment on the hydrogen fuel cell body 3, thereby reflecting the intelligence of the cooling system.

[0028] The working principle and usage process of the present invention are as follows: first, open the cover 6, place the hydrogen fuel cell body 3 into the interior of the cooling box 1, so that the bottom of the hydrogen fuel cell body 3 and the top of the partition 2 are in contact, and then rotate the adjustment rod 42 to rotate inside the adjustment sleeve 41. The adjustment rod 42 will drive the fixing plate 5 to move horizontally, so that the fixing plate 5 approaches the side of the hydrogen fuel cell body 3 until the fixing plate 5 and the hydrogen fuel cell body 3 are in close contact, thereby facilitating the adjustment and fixation of the hydrogen fuel cell body 3; Then, when the hydrogen fuel cell body 3 is in operation, the temperature sensing probe 18 will detect the temperature inside the cooling box 1 in real time, and transmit the detected temperature value information to the signal receiving module 191 in the form of a signal, and the signal receiving module 191 will transmit the received signal to the signal processing module 193. At this time, the signal processing module 193 will amplify the signal. If the temperature value detected by the temperature sensing probe 18 is greater than the temperature value range set by the value setting module 192, the circuit control module 194 will connect the circuits of the heat dissipation motor 72 and the liquid supply pump 14, so that the heat dissipation motor 72 and the liquid supply pump 14 will run due to power-on and dissipate heat for the hydrogen fuel cell body 3 inside the cooling box 1. If the temperature value detected by the temperature sensing probe 18 is less than the temperature value range set by the value setting module 192, the circuit control module 194 will disconnect the circuits of the heat dissipation motor 72 and the liquid supply pump 14, so that the heat dissipation motor 72 and the liquid supply pump 14 will stop running due to power failure. Then, when the hydrogen fuel cell body 3 needs to dissipate heat, the heat dissipation motor 72 is turned on, causing the rotating shaft 71 to rotate, and the rotating shaft 71 drives the fan blades 73 to rotate, thereby generating wind power, thereby facilitating heat dissipation and cooling of the hydrogen fuel cell body 3. At the same time, the outside air will flow into the interior of the cooling box 1 from the air inlet 8, and the high-temperature heat will be discharged from the heat dissipation port 10, thereby facilitating the exchange of air inside the cooling box 1. Finally, start the liquid supply pump 14, and use the liquid supply pipe 13 to transport the coolant inside the liquid storage box 12 to the inside of the liquid inlet pipe 15, and the coolant will flow into the inside of the fixed plate 5 along the liquid inlet pipe 15, and flow in the circulation groove inside the fixed plate 5. At this time, the heat on the surface of the hydrogen fuel cell body 3 will be transferred to the flowing coolant through the metal fixed plate 5, so that the coolant can carry away the heat, thereby facilitating the cooling of the surface of the hydrogen fuel cell body 3. At the same time, the coolant with heat will flow into the inside of the return pipe 16 along the liquid outlet pipe 17, and the wind force generated by the fan blades 73 will cool the coolant in the return pipe 16, and the cooled coolant will flow back to the inside of the liquid storage box 12, thereby facilitating the recycling of the coolant.
