Description

Technical Field

[0001] This utility model relates to the field of water electrolysis hydrogen production technology, specifically a PEM water electrolysis hydrogen production tank. Background Technology

[0002] Water electrolysis is a relatively convenient method for producing hydrogen. Direct current is passed through an electrolytic cell filled with electrolyte, causing water molecules to undergo an electrochemical reaction at the electrodes, decomposing into hydrogen and oxygen. Pure water is used as a raw material in water electrolysis. However, since pure water is a weak electrolyte, a certain amount of electrolyte (such as sodium hydroxide or sulfuric acid) needs to be added to improve its conductivity, thereby increasing the efficiency of hydrogen production. However, in current technology, the mass of pure water to be electrolyzed needs to be manually measured, and then an appropriate amount of electrolyte is added based on the volume of pure water to improve conductivity. This method requires a large amount of manpower, reduces automation, and cannot meet the needs of hydrogen production.

[0003] For example, according to the authorization announcement number CN202322122890.0, this utility model discloses a PEM electrolysis water hydrogen production tank, which relates to the field of PEM electrolysis water hydrogen production. The hydrogen production tank includes an electrolysis tank, an outer box fixedly installed on the outside of the electrolysis tank, a box cover fitted on the upper end of the electrolysis tank, a cooling box fixedly installed on the outside of the outer box, a drain pipe connected to one side of the electrolysis tank, an anode plate and a cathode plate respectively fitted on the lower end of the electrolysis tank, a cooling mechanism for facilitating cooling of the electrolysis tank on the upper end of the mounting plate, and a mixing mechanism for facilitating mixing of the raw materials inside the electrolysis tank on the lower end of the mounting plate. The cooling mechanism facilitates the dissipation of heat generated inside the electrolysis tank during operation, preventing high temperature during operation, and the mixing mechanism facilitates mixing of the raw materials inside the electrolysis tank, improving the conductivity of pure water.

[0004] Based on the above patent searches and the findings of existing equipment, while the above-mentioned equipment can solve the problems of existing PEM pure water electrolysis hydrogen production tanks, which are mostly made of PE material and food-grade 316 stainless steel, the high mold cost of PE material tanks and the softening of PE material due to the increased water temperature during hydrogen production system startup, which affects the service life, and the high purity requirements for pure water hydrogen production and the extremely strict requirements for stainless steel materials, resulting in high material costs, and the fact that stainless steel tanks are usually made by bending sheet metal and then welding, resulting in weld points, which can lead to impurities affecting water quality if not handled properly, the cooling structure of the hydrogen production device does not have a heat dissipation structure. The semiconductor cooling chip generates a lot of heat at its heating end during operation, and if it is not dissipated in time, it can affect the cooling effect of the semiconductor cooling chip, thus affecting its cooling efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PEM electrolysis water hydrogen production tank, comprising a support leg, a base plate, a water tank, a hydrogen production tank, and a water pump. The top of the support leg is fixedly connected to the bottom of the base plate. The rear side of the top of the base plate is fixedly connected to the bottom of the water tank. The front side of the top of the base plate is fixedly connected to the bottom of the hydrogen production tank.

Fixing plates are fixedly connected to both sides of the back of the water tank. A cooling fan is movably connected to the inner side of the fixing plate. An installation assembly is provided on the top of the fixing plate. A stirring assembly is provided on the top of the water tank.

[0007] As a preferred embodiment of this utility model, the mounting component includes a mounting groove, which is formed on the top of the fixing plate.

[0009] As a preferred embodiment of this invention, a heat sink is fixedly connected to the back of the cooling chip, and a plurality of heat sinks are provided and distributed at equal intervals.

[0010] As a preferred embodiment of this utility model, a limiting plate is movably connected to the top of the fixing plate, and reinforcing grooves are provided on both sides of the top of the limiting plate and the rear side of the top of the fixing plate, with reinforcing rods threadedly connected to the inner wall of the reinforcing grooves.

[0011] As a preferred embodiment of this utility model, an auxiliary block is fixedly connected to the top of the reinforcing rod, and an auxiliary strip is fixedly connected to the surface of the auxiliary block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a fixing plate and a cooling fan, allows the user to easily install the cooling fan, and the cooling fan can quickly dissipate the heat emitted by the cooling chip into the air, avoiding the accumulation of heat in the cooling chip. This solves the problem that the cooling structure of the hydrogen production device does not have a heat dissipation structure. When the semiconductor cooling chip is working, the heat-generating end will generate a lot of heat. If it is not dissipated in time, it will easily affect the cooling effect of the semiconductor cooling chip, thus affecting its cooling efficiency. This invention achieves the effect of auxiliary heat dissipation.

[0015] 2. By setting up an installation component, when a user needs to install a cooling fan, first align the bottom of the mounting strips on both sides of the cooling fan with the mounting groove, and then move the cooling fan downwards so that the mounting strips are completely moved into the inside of the mounting groove. The mounting groove can restrict the movement direction of the mounting strips, so that the mounting strips cannot automatically detach from the fixing plate. Thus, the cooling fan can be placed between the fixing plates, thereby achieving the effect of facilitating the user to install the cooling fan.

[0016] 3. This utility model, by setting up a stirring component, allows the cooling plate to be turned on to lower the water temperature inside the tank. When the user turns on the cooling plate to lower the water temperature, the cooling plate can only lower the temperature of the water on the side closest to the cooling plate. By rotating the rotating rod, the stirring rod can be rotated, which can agitate the water inside the tank, so that all the water inside the tank can come into contact with the cooling plate, thereby making the water temperature inside the tank more uniform. The rotating groove can restrict the movement direction of the rotating rod, making the rotation of the rod more stable. The turntable can increase the contact area between the user and the rotating rod, making the rotating rod easier to rotate, thus achieving the effect of equalizing the water temperature inside the tank.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the present invention provides a PEM electrolysis water hydrogen production tank, including a support leg 1, a base plate 2, a water tank 3, a hydrogen production tank 4, and a water pump 5. The top of the support leg 1 is fixedly connected to the bottom of the base plate 2. The rear side of the top of the base plate 2 is fixedly connected to the bottom of the water tank 3. The front side of the top of the base plate 2 is fixedly connected to the bottom of the hydrogen production tank 4. The left side of the rear side of the top of the base plate 2 is fixedly connected to the bottom of the water pump 5. The output end of the water pump 5 is connected to the water tank 3 through a conduit. The output end of the water pump 5 is connected to the hydrogen production tank 4 through a conduit. Cooling plates 6 are embedded on both sides of the back of the water tank 3. Fixing plates 7 are fixedly connected to both sides of the back of the water tank 3. A cooling fan 8 is movably connected to the inner side of the fixing plate 7. An installation component 9 is provided on the top of the fixing plate 7. A stirring component 10 is provided on the top of the water tank 3.

[0024] refer to Figure 3 The mounting component 9 includes a mounting slot 91, which is located on the top of the fixing plate 7. A mounting strip 92 is slidably connected inside the mounting slot 91, and the inner side of the mounting strip 92 is fixedly connected to both sides of the cooling fan 8.

[0025] As a technical optimization of this utility model, by setting the installation component 9, when the user needs to install the cooling fan 8, first align the bottom of the mounting strips 92 on both sides of the cooling fan 8 with the mounting groove 91, and then move the cooling fan 8 downward so that the mounting strips 92 are completely moved into the interior of the mounting groove 91. The mounting groove 91 can restrict the movement direction of the mounting strips 92 so that the mounting strips 92 cannot automatically detach from the fixing plate 7, and thus the cooling fan 8 can be placed between the fixing plates 7, thereby achieving the effect of facilitating the user to install the cooling fan 8.

[0026] refer to Figure 2The stirring assembly 10 includes a rotating trough 101, which is located on the top of the water tank 3. A rotating rod 102 is slidably connected to the inner wall of the rotating trough 101. A turntable 103 is fixedly connected to the top of the surface of the rotating rod 102. A stirring rod 104 is fixedly connected to the bottom of the surface of the rotating rod 102. Several stirring rods 104 are arranged in a ring and are evenly distributed.

[0027] As a technical optimization of this utility model, by setting up a stirring component 10, when the user turns on the cooling plate 6 to lower the water temperature inside the water tank 3, the cooling plate 6 can only lower the temperature of the water in the water tank 3 on the side closest to the cooling plate 6. By rotating the rotating rod 102, the stirring rod 104 is driven to rotate, and the stirring rod 104 can stir the water inside the water tank 3, so that all the water inside the water tank 3 can come into contact with the cooling plate 6, thereby making the water temperature inside the water tank 3 more uniform. The rotating groove 101 can restrict the movement direction of the rotating rod 102, making the rotation of the rotating rod 102 more stable. The turntable 103 can increase the contact area between the user and the rotating rod 102, making the rotating rod 102 easier to rotate, thereby achieving the effect of equalizing the water temperature inside the water tank 3.

[0028] refer to Figure 2 A heat sink 11 is fixedly connected to the back of the cooling chip 6. Several heat sinks 11 are provided and are distributed at equal intervals.

[0029] As a technical optimization of this utility model, by setting heat sink 11, when the user turns on the cooling chip 6, the contact area between the cooling chip 6 and the air can be increased by using multiple heat sinks 11, which allows the heat on the cooling chip 6 to be diffused into the air more quickly, making the cooling chip 6 heat dissipation effect better, thereby achieving the effect of assisting the cooling chip 6 in heat dissipation.

[0030] refer to Figure 4 The top of the fixed plate 7 is movably connected to the limiting plate 12. The two sides of the top of the limiting plate 12 and the rear side of the top of the fixed plate 7 are provided with reinforcing grooves 13. The inner wall of the reinforcing groove 13 is threaded with a reinforcing rod 14.

[0031] As a technical optimization of this utility model, by setting a limiting plate 12, a reinforcing groove 13, and a reinforcing rod 14, after the user installs the cooling fan 8 between the fixing plates 7, the limiting plate 12 is placed on top of the fixing plate 7. At this time, the reinforcing groove 13 on the top of the limiting plate 12 is connected to the reinforcing groove 13 on the top of the fixing plate 7. Then, the reinforcing rod 14 is aligned with the reinforcing groove 13. At this time, the reinforcing rod 14 is rotated so that the reinforcing rod 14 is completely moved into the interior of the reinforcing groove 13. The reinforcing rod 14 can connect the limiting plate 12 and the fixing plate 7 together. The limiting plate 12 prevents the mounting strip 92 from moving out of the mounting groove 91, thereby achieving the effect of restricting the movement of the mounting strip 92.

[0032] refer to Figure 4 An auxiliary block 15 is fixedly connected to the top of the reinforcing rod 14, and an auxiliary strip 16 is fixedly connected to the surface of the auxiliary block 15. Several auxiliary strips 16 are provided and are distributed in a ring at equal intervals.

[0033] As a technical optimization of this utility model, by setting up auxiliary blocks 15 and auxiliary strips 16, when using this reinforcing rod 14 that needs to be rotated, the auxiliary blocks 15 can increase the contact area between the user and the reinforcing rod 14, making it easier for the user to apply force. Furthermore, the multiple auxiliary strips 16 can increase the friction between the user and the auxiliary blocks 15, making it easier for the user to rotate the auxiliary blocks 15, thereby achieving the effect of assisting the rotation of the reinforcing rod 14.

[0034] refer to Figure 4 A guide groove 17 is provided on the front side of the top of the fixed plate 7. A guide block 18 is slidably connected to the inner wall of the guide groove 17. The top of the guide block 18 is fixedly connected to the bottom of the limiting plate 12.

[0035] As a technical optimization of this utility model, by setting the guide groove 17 and the guide block 18, when the user needs to install the limiting plate 12 onto the fixing plate 7, first align the guide block 18 at the bottom of the limiting plate 12 with the guide groove 17, and then move the limiting plate 12 downward so that the guide block 18 is completely moved into the interior of the guide groove 17. When the guide block 18 is completely moved into the interior of the guide groove 17, the reinforcing groove 13 on the limiting plate 12 will be connected with the reinforcing groove 13 at the top of the fixing plate 7, thereby achieving the effect of assisting in limiting installation.

[0036] The working principle and usage process of this utility model are as follows: The fixing plate 7 facilitates the installation of the cooling fan 8. The cooling fan 8 rapidly dissipates the heat emitted by the cooling coil 6 into the air, preventing heat accumulation. Multiple heat sinks 11 increase the contact area between the cooling coil 6 and the air, allowing the heat from the cooling coil 6 to dissipate more quickly. When installing the cooling fan 8, first align the bottom of the mounting strips 92 on both sides of the cooling fan 8 with the mounting grooves 91, then move the cooling fan 8 downwards until the mounting strips 92 are fully inside the mounting grooves 91. The mounting grooves 91 restrict the movement of the mounting strips 92, preventing them from automatically detaching from the fixing plate 7. The cooling fan 8 can then be placed between the fixing plates 7. When the user turns on the cooling coil 6 to lower the water temperature inside the water tank 3, the cooling coil 6 can only lower the temperature of the water in the water tank 3 closest to the cooling coil 6. This is achieved by rotating the rotating rod 102. The stirring rod 104 rotates, stirring the water inside the water tank 3 so that all the water in the water tank 3 can come into contact with the cooling plate 6, thereby making the water temperature inside the water tank 3 more even. The rotating groove 101 restricts the movement direction of the rotating rod 102, making the rotation of the rotating rod 102 more stable. The turntable 103 increases the contact area between the user and the rotating rod 102, making the rotation of the rotating rod 102 easier. After the user installs the cooling fan 8 between the fixing plates 7, the limiting plate 12 is placed on top of the fixing plate 7. At this time, the reinforcing groove 13 on the top of the limiting plate 12 is connected to the reinforcing groove 13 on the top of the fixing plate 7. Then, the reinforcing rod 14 is aligned with the reinforcing groove 13. At this time, the reinforcing rod 14 is rotated so that the reinforcing rod 14 is completely moved into the interior of the reinforcing groove 13. The reinforcing rod 14 connects the limiting plate 12 and the fixing plate 7 together. The limiting plate 12 prevents the mounting strip 92 from moving out of the mounting groove 91, thereby achieving the effect of auxiliary heat dissipation.

[0037] In summary, this PEM electrolysis water hydrogen production tank, by setting up a fixing plate 7 and a cooling fan 8, allows for easy installation of the cooling fan 8 by the fixing plate 7. The cooling fan 8 can then quickly dissipate the heat emitted by the cooling chip 6 into the air, preventing the heat from accumulating in the cooling chip 6. This solves the problem that the cooling structure of the hydrogen production device lacks a heat dissipation structure. When the semiconductor cooling chip is working, the heat-generating end generates a large amount of heat, which, if not dissipated in time, can easily affect the cooling effect of the semiconductor cooling chip, thus affecting its cooling efficiency.
