Description

Technical Field

[0001] The present invention belongs to the technical field of hydrogen production by electrolysis of water, and particularly relates to a PEM electrolytic water hydrogen production device capable of rapid heat dissipation. Background Art

[0002] PEM electrolytic water hydrogen production is a new hydrogen production technology, which has the advantages of high hydrogen production purity (>99.99%), high energy conversion efficiency, fast response speed, small floor area, etc. The working principle of PEM electrolytic water hydrogen production technology is that water molecules are decomposed into oxygen and hydrogen positive ions (H+) under the catalysis of an anode catalyst (such as a noble metal iridium catalyst), and then the H+ passes through the PEM membrane between the anode and cathode and generates hydrogen under the catalysis of a cathode catalyst (such as a noble metal platinum catalyst).

[0003] However, a large amount of heat is generated during the operation of the PEM electrolytic water hydrogen production device, resulting in an increase in the temperature of the electrolytic cell. If it is in a high-temperature state for a long time, it will not only affect the performance of the equipment, but also may cause equipment damage. Therefore, it is necessary to dissipate heat from the PEM electrolytic water hydrogen production device in a timely and effective manner. Summary of the Invention

[0004] Aiming at the above problems, the present invention aims to provide a PEM electrolytic water hydrogen production device capable of rapid heat dissipation, which solves the problem that the existing PEM electrolytic water hydrogen production device lacks effective heat dissipation means.

[0005] In order to achieve the above invention purpose, the technical scheme adopted by the present invention is as follows:

[0006] There is provided a PEM electrolytic water hydrogen production device capable of rapid heat dissipation, which includes a control system, a PEM electrolytic cell, a DC power supply, a water tank, an end plate heat dissipation device and a water circulation heat dissipation device; an end plate heat dissipation device is provided on each of the two end plates of the PEM electrolytic cell, and a water inlet, an oxygen water outlet and a hydrogen gas outlet are provided on one of the end plates of the PEM electrolytic cell; the DC power supply is electrically connected to the cathode plate and the anode plate of the PEM electrolytic cell; the water tank is communicated with the water inlet and the oxygen water outlet of the PEM electrolytic cell through pipelines, a first water pump is provided on the pipeline between the water tank and the water inlet of the PEM electrolytic cell, and the water circulation heat dissipation device is connected to the water channel between the water tank and the PEM electrolytic cell; the control system is electrically connected to the end plate heat dissipation device, the water circulation heat dissipation device and the first water pump.

[0007] Further, as a specific setting mode of the end - plate heat dissipation device, each of the end - plate heat dissipation devices includes a heat dissipation plate. One end face of the heat dissipation plate is fixedly connected to the end plate of the PEM electrolyzer. A first temperature sensor is arranged between the heat dissipation plate and the end plate of the PEM electrolyzer. A semiconductor refrigeration sheet and a radiator are arranged on the other end face of the heat dissipation plate. The cold end of the semiconductor refrigeration sheet is in contact with the end face of the heat dissipation plate, and the radiator is in contact with the hot end of the semiconductor refrigeration sheet. The first temperature sensor, the semiconductor refrigeration sheet, and the radiator are all electrically connected to the control system.

[0008] The working principle of the end - plate heat dissipation device is as follows: When the first temperature sensor detects that the temperature of the end plate of the PEM electrolyzer is too high, the control system starts the end - plate heat dissipation device to work. The heat of the end plate is transferred to the heat dissipation plate. The semiconductor refrigeration sheet is powered on. The cold end of the semiconductor refrigeration sheet takes away the heat of the heat dissipation plate to cool it down. The heat at the hot end of the semiconductor refrigeration sheet is quickly discharged through the radiator, and finally the technical effect of cooling the end plate is achieved.

[0009] Further, a refrigerant circulation channel is arranged inside each heat dissipation plate. The refrigerant circulation channel is arranged in a curved snake - like shape inside the heat dissipation plate. The two ends of the refrigerant circulation channel are respectively an air inlet and an air outlet. The air inlet and the air outlet are both located outside the heat dissipation plate and are connected to the refrigerant circulation equipment. Arranging the refrigerant circulation channel inside the heat dissipation plate can increase the heat dissipation effect of the heat dissipation plate.

[0010] Further, a plurality of heat dissipation fins are arranged on the radiator. The design of the plurality of heat dissipation fins increases the heat dissipation area and improves the heat dissipation effect.

[0011] Further, a heat - conducting material is arranged between the radiator and the semiconductor refrigeration sheet. A cooling fan electrically connected to the control system is arranged on the outside of the radiator. Specifically, the heat - conducting material is one of heat - conducting glue, heat - conducting silicone grease, and phase - change material, which is used to enhance the heat transfer effect between the radiator and the semiconductor refrigeration sheet. The setting of the cooling fan serves to introduce the heat in the radiator into the external environment, thereby improving the heat dissipation capacity of the entire end - plate heat dissipation device. At the same time, the magnitude of the current of the semiconductor refrigeration sheet, the flow rate of the refrigerant in the refrigerant circulation channel, and the rotation speed of the cooling fan can also be adjusted through the control system, so as to control the temperature of the end - plate heat dissipation device within the set range.

[0012] Further, as a specific setting mode of the water - cycle heat dissipation device, the water - cycle heat dissipation device includes a water - collecting tank. Two partition plates are arranged in the water - collecting tank. The two partition plates divide the water - collecting tank into independent hot - water area, cooling area, and cold - water area.

[0013] The hot water area is connected to the oxygen water inlet through a pipeline, and a second temperature sensor is arranged in the hot water area; a cooling pipeline is arranged between the hot water area and the cold water area, and both ends of the cooling pipeline are respectively connected to the hot water area and the cold water area. The middle part of the cooling pipeline is located in the cooling area and a second water pump is arranged thereon. A cooling device is arranged in the cooling area; the cold water area is connected to the water tank through a pipeline, and a solenoid valve switch and a third water pump are arranged on the pipeline between the cold water area and the water tank. A third temperature sensor is arranged in the cold water area; the second temperature sensor, the second water pump, the cooling device, the solenoid valve switch, the third water pump and the third temperature sensor are all electrically connected to the control system.

[0014] The working principle of the water circulation heat dissipation device is as follows: when the second temperature sensor detects that the water temperature flowing out of the oxygen water inlet is too high, the cooling device is started through the control system. The cooling device cools the cooling pipeline in the cooling area, and the cooled water is pumped into the cold water area for storage through the second water pump. When the third temperature sensor detects that the water in the cold water area is within the preset range, the control system opens the solenoid valve switch and starts the third water pump to pump the water in the cold water area into the water tank for use by the PEM electrolyzer. The water supply process of the PEM electrolyzer is: the water in the water tank is pumped into the PEM electrolyzer through the first water pump.

[0015] Further, a circulation pipeline is arranged between the hot water area and the cold water area. Both ends of the circulation pipeline are respectively connected to the hot water area and the cold water area. The middle part of the circulation pipeline is located in the cooling area and a fourth water pump electrically connected to the control system is arranged thereon. The reason for arranging the circulation pipeline is to cool the water multiple times to ensure that the water in the cold water area is within the preset range. The cooling process is as follows: when the third temperature sensor detects that the water in the cold water area is not within the preset range, the fourth water pump is started through the control system. The fourth water pump pumps the water into the hot water area through the circulation pipeline. During the process of the water flowing in the circulation pipeline, the water is cooled repeatedly until the water in the cold water area is within the preset range, and then the fourth water pump is stopped. The above solution cools the water multiple times to ensure that the water in the cold water area is within the preset range.

[0016] Further, the middle parts of both the cooling pipeline and the circulation pipeline are arranged in a bent snake shape. The cooling pipeline and the circulation pipeline arranged in a bent snake shape can increase the length of their own pipelines and enhance the cooling effect.

[0017] Further, as a specific setting manner of the cooling device, the cooling device includes a porous material and a plurality of cooling fans. The porous material is filled in the cooling area, a coolant is arranged in the cooling area, and both the cooling pipeline and the circulation pipeline are located inside the porous material. The plurality of cooling fans are all electrically connected to the control system, and the plurality of cooling fans are arranged at the top of the cooling area, and each cooling fan guides the gas in the cooling area to the outside. The settings of the porous material and the cooling fans can accelerate the volatilization of the coolant, take away the heat in the cooling area, and ensure the cooling effect of the cooling pipeline and the circulation pipeline on water.

[0018] Further, the oxygen water inlet is connected with a gas-liquid separator through a pipeline. The gas outlet of the gas-liquid separator is communicated with an oxygen collection device through a pipeline, and the liquid outlet of the gas-liquid separator is communicated with the hot water area through a pipeline. The hydrogen gas inlet is connected with a hydrogen collection device through a pipeline.

[0019] The beneficial effects of the present invention are as follows:

[0020] In the PEM electrolytic water hydrogen production device capable of quickly dissipating heat in the present invention, by providing an end plate heat dissipation device and a water circulation heat dissipation device, the two end plates of the PEM electrolytic cell and the pure water entering the PEM electrolytic cell are respectively cooled, thereby realizing efficient heat dissipation of the PEM electrolytic cell, avoiding the overhigh temperature of the PEM electrolytic cell, and ensuring the long-term stable operation of the PEM electrolytic water hydrogen production device.

For those of ordinary skill in the art of this technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions created using the concept of the present invention are within the scope of protection.

[0026] As shown in Figure 1 the figure, the present invention provides a PEM electrolytic water hydrogen production device capable of rapid heat dissipation, which includes a control system, a PEM electrolytic cell 1, a DC power supply 2, a water tank 3, an end plate heat dissipation device 4, and a water circulation heat dissipation device 5; one end plate heat dissipation device 4 is provided on each of the two end plates 10 of the PEM electrolytic cell 1, and a water inlet 6, an oxygen outlet 7, and a hydrogen outlet 8 are provided on one of the end plates 10 of the PEM electrolytic cell 1; the DC power supply 2 is electrically connected to the cathode plate and the anode plate of the PEM electrolytic cell 1; the water tank 3 is connected to the water inlet 6 and the oxygen outlet 7 of the PEM electrolytic cell 1 through pipelines, a first water pump 9 is provided on the pipeline between the water tank 3 and the water inlet 6 of the PEM electrolytic cell 1, and the water circulation heat dissipation device 5 is connected to the water channel between the water tank 3 and the PEM electrolytic cell 1; the control system is electrically connected to the end plate heat dissipation device 4, the water circulation heat dissipation device 5, and the first water pump 9.

[0027] By providing the end plate heat dissipation device 4 and the water circulation heat dissipation device 5, the two end plates 10 of the PEM electrolytic cell 1 and the pure water entering the PEM electrolytic cell 1 are respectively cooled, thereby realizing efficient heat dissipation of the PEM electrolytic cell 1, avoiding the overheating of the PEM electrolytic cell 1, and ensuring the long-term stable operation of the PEM electrolytic water hydrogen production device.

[0028] Specifically, as shown in Figure 2 the figure, as a specific setting manner of the end plate heat dissipation device 4, each end plate heat dissipation device 4 includes a heat dissipation plate 11, one side end face of the heat dissipation plate 11 is fixedly connected to the end plate 10 of the PEM electrolytic cell 1, a first temperature sensor is provided between the heat dissipation plate 11 and the end plate 10 of the PEM electrolytic cell 1, and a semiconductor refrigeration sheet 12 and a radiator 13 are provided on the other side end face of the heat dissipation plate 11; the cold end of the semiconductor refrigeration sheet 12 is in contact with the end face of the heat dissipation plate 11, and the radiator 13 is in contact with the hot end of the semiconductor refrigeration sheet 12; the first temperature sensor, the semiconductor refrigeration sheet 12, and the radiator 13 are all electrically connected to the control system.

[0029] When the first temperature sensor detects that the temperature of the end plate 10 of the PEM electrolyzer 1 is too high, the control system starts the end plate heat dissipation device 4 to work. The heat of the end plate 10 is transferred to the heat dissipation plate 11, the semiconductor refrigeration chip 12 is powered on, the cold end of the semiconductor refrigeration chip 12 takes away the heat of the heat dissipation plate 11 to cool it down, and the heat at the hot end of the semiconductor refrigeration chip 12 is quickly discharged through the radiator 13, finally achieving the technical effect of dissipating heat and cooling the end plate 10.

[0030] Preferably, a refrigerant circulation channel 14 is provided inside each of the heat dissipation plates 11. The refrigerant circulation channel 14 is arranged in a curved snake shape inside the heat dissipation plate 11. The two ends of the refrigerant circulation channel 14 are respectively an air inlet 15 and an air outlet 16. The air inlet 15 and the air outlet 16 are both located outside the heat dissipation plate 11 and are connected to the refrigerant circulation device. Arranging the refrigerant circulation channel 14 inside the heat dissipation plate 11 can increase the heat dissipation effect of the heat dissipation plate 11.

[0031] Specifically, a plurality of heat dissipation fins are provided on the radiator 13. The radiator 13 is made of aluminum, and aluminum has excellent thermal conductivity, which can quickly transfer the heat of the end plate 10 and improve the cooling efficiency. The design of a plurality of heat dissipation fins increases the heat dissipation area and improves the heat dissipation effect. At the same time, the cost of aluminum is relatively low, which can reduce the production cost of the entire end plate heat dissipation device 4.

[0032] Furthermore, a heat-conducting material is provided between the radiator 13 and the semiconductor refrigeration chip 12. The heat-conducting material is one of heat-conducting glue, heat-conducting silicone grease, and phase-change material, which is used to enhance the heat transfer effect between the radiator 13 and the semiconductor refrigeration chip 12; a heat dissipation fan 17 electrically connected to the control system is provided on the outside of the radiator 13. The setting of the heat dissipation fan 17 serves to introduce the heat in the radiator 13 into the external environment, thereby improving the heat dissipation capacity of the entire end plate heat dissipation device 4; at the same time, the size of the current of the semiconductor refrigeration chip 12, the flow rate of the refrigerant in the refrigerant circulation channel 14, and the rotation speed of the heat dissipation fan 17 can also be adjusted through the control system, thereby controlling the temperature of the end plate heat dissipation device 4 to be maintained within a set range.

[0033] Specifically, as Figure 1 and Figure 3 shown, as a specific setting method of the water circulation heat dissipation device 5, the water circulation heat dissipation device 5 includes a water collecting tank 18. Two partition plates 19 are provided in the water collecting tank 18. The two partition plates 19 divide the water collecting tank 18 into independent hot water areas 20, cooling areas 21, and cold water areas 22;

[0034] The hot water area 20 is connected to the oxygen water inlet 7 through a pipeline, and a second temperature sensor is arranged in the hot water area 20; a cooling pipeline 23 is arranged between the hot water area 20 and the cold water area 22. Both ends of the cooling pipeline 23 are respectively connected to the hot water area 20 and the cold water area 22. The middle part of the cooling pipeline 23 is located in the cooling area 21 and a second water pump 24 is arranged thereon. A cooling device 25 is arranged in the cooling area 21; the cold water area 22 is connected to the water tank 3 through a pipeline, and a solenoid valve switch 26 and a third water pump 27 are arranged on the pipeline between the cold water area 22 and the water tank 3. A third temperature sensor is arranged in the cold water area 22; the second temperature sensor, the second water pump 24, the cooling device 25, the solenoid valve switch 26, the third water pump 27 and the third temperature sensor are all electrically connected to the control system.

[0035] The principle of the water circulation heat dissipation device 5 is as follows: When the second temperature sensor detects that the water temperature flowing out of the oxygen water inlet 7 is too high, the cooling device 25 is started through the control system. The cooling device 25 cools the cooling pipeline 23 in the cooling area 21, and the cooled water is pumped into the cold water area 22 for storage through the second water pump 24. When the third temperature sensor detects that the water in the cold water area 22 is within the preset range, the control system turns on the solenoid valve switch 26 and starts the third water pump 27 to pump the water in the cold water area 22 into the water tank 3 for use by the PEM electrolyzer 1. The water supply process of the PEM electrolyzer 1 is as follows: The water in the water tank 3 is pumped into the PEM electrolyzer 1 through the first water pump 9.

[0036] Specifically, a circulation pipeline 28 is arranged between the hot water area 20 and the cold water area 22. Both ends of the circulation pipeline 28 are respectively connected to the hot water area 20 and the cold water area 22. The middle part of the circulation pipeline 28 is located in the cooling area 21 and a fourth water pump 29 electrically connected to the control system is arranged thereon. When the third temperature sensor detects that the water in the cold water area 22 is not within the preset range, the fourth water pump 29 is started through the control system. The fourth water pump 29 pumps the water into the hot water area 20 through the circulation pipeline 28. During the process of the water flowing in the circulation pipeline 28, the water is cooled repeatedly until the water in the cold water area 22 is within the preset range, and then the fourth water pump 29 is stopped. The above solution cools the water multiple times to ensure that the water in the cold water area 22 is within the preset range.

[0037] Preferably, since it takes a certain amount of time to cool the water, the water will stay in the hot water area 20 for a long time. At this time, in order to prevent the water in the hot water area 20 from overflowing, the volume of the hot water area 20 is set to be twice that of the cold water area 22 to increase the capacity of the hot water area 20 and avoid the water from overflowing during the circulation between the hot water area 20 and the cold water area 22.

[0038] The middle parts of the cooling pipe 23 and the circulation pipe 28 are both arranged in a bent serpentine shape. The cooling pipe 23 and the circulation pipe 28 arranged in a bent serpentine shape can increase the length of their own pipes and enhance the cooling effect.

[0039] Specifically, as Figure 3 shown, as a specific setting mode of the cooling device 25, the cooling device 25 includes a porous material 30 and a plurality of cooling fans 31. The porous material 30 is filled in the cooling area 21. A coolant is provided in the cooling area 21. The cooling pipe 23 and the circulation pipe 28 are both located inside the porous material 30; a plurality of the cooling fans 31 are all electrically connected to the control system. The plurality of cooling fans 31 are arranged on the top of the cooling area 21. Each cooling fan 31 guides the gas in the cooling area 21 to the outside. The settings of the porous material 30 and the cooling fans 31 can accelerate the volatilization of the coolant, take away the heat in the cooling area 21, and ensure the cooling effect of the cooling pipe 23 and the circulation pipe 28 on water.

[0040] Specifically, the oxygen water inlet 7 is connected to a gas-liquid separator 32 through a pipe. The gas outlet of the gas-liquid separator 32 is communicated with an oxygen collection device 33 through a pipe. The liquid outlet of the gas-liquid separator 32 is communicated with the hot water area 20 through a pipe; the hydrogen gas outlet 8 is connected to a hydrogen collection device 34 through a pipe.
