Description

Technical Field

[0001] This utility model relates to the field of formic acid hydrogen production technology, and more specifically to a crossflow heat dissipation system for formic acid hydrogen production equipment. Background Technology

[0002] In recent years, as the hydrogen energy industry has developed towards large-scale and high power density, the operating load and continuous working time of formic acid hydrogen production equipment have increased significantly, and the requirements for the overall operational stability of the equipment have become increasingly stringent.

[0003] To ensure the safety and reliability of the core reaction, existing formic acid to hydrogen production equipment typically employs a closed cabinet structure. This structure isolates the equipment from external dust, moisture, and other impurities, preventing them from interfering with the catalytic reaction process and improving operator safety. However, while existing cabinets allow for air exchange with the outside, the heat generated by the equipment and piping inside cannot be quickly dissipated, resulting in significant heat dissipation deficiencies. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A crossflow cooling system for a formic acid hydrogen production equipment is provided. The formic acid hydrogen production equipment body has a first fixed plate and a second fixed plate respectively on its two opposite side walls. The first fixed plate has an air inlet grille, and the second fixed plate has an air outlet grille. The air inlet grille and the air outlet grille connect the interior of the formic acid hydrogen production equipment body with the outside air. A crossflow fan is installed on the air outlet grille on one side inside the formic acid hydrogen production equipment body. The air inlet of the crossflow fan faces the interior of the formic acid hydrogen production equipment, and the air outlet faces the air outlet grille.

[0006] The present invention is further configured such that: the air outlet grille is provided with an air guide plate on one side inside the formic acid hydrogen production equipment body, the air guide plate covers the air outlet grille, the air guide plate has a through hole, and the air outlet of the crossflow fan is connected to the through hole.

[0007] The present invention is further configured such that: the edge of the air guide plate is provided with a bent portion, the bent portion is arranged around the edge of the air guide plate, and the bent portion is attached to the second fixing plate.

[0008] The present invention is further configured such that: the air inlet of the crossflow fan is opened at the bottom of the crossflow fan, and the air outlet of the crossflow fan is horizontally opened on the side wall of the crossflow fan.

[0009] The present invention is further configured such that: the air outlet grille includes an outer frame, and a plurality of grille blades are arranged on the outer frame along the vertical direction. The grille blades are rotatably connected to the outer frame. The crossflow fan blows the grille blades to rotate and form an air outlet channel. The grille blades are reset by gravity or torsion spring.

[0010] The present invention is further configured such that a filter screen is provided on the air inlet grille on one side inside and / or the other side outside the formic acid hydrogen production equipment body.

[0011] The present invention is further configured such that: the first fixing plate and the second fixing plate are integrally formed with the side wall of the formic acid hydrogen production equipment body, or the first fixing plate and the second fixing plate are fixed to the side wall of the formic acid hydrogen production equipment body by fasteners.

[0012] The present invention is further configured such that: the first fixing plate and the second fixing plate are located at the top of the formic acid hydrogen production equipment body, and the air inlet grille and the air outlet grille are located at the same height.

[0013] Compared with the prior art, the present invention has at least the following advantages:

[0014] 1. By setting up an air inlet grille, an air outlet grille, and a crossflow fan, a horizontal heat dissipation airflow channel is constructed in the formic acid hydrogen production system. The crossflow fan can actively extract hot air from inside the equipment and guide it to the air outlet grille for discharge. At the same time, it can introduce cold air from the outside through the air inlet grille, effectively breaking the heat accumulation problem of the closed cabinet. During the operation of the formic acid hydrogen production system, it can dissipate heat for the system in real time, avoid the high temperature inside and outside affecting the overall performance of the system, and maintain the stable progress of the catalytic reaction.

[0015] 2. By installing a guide plate between the crossflow fan and the air outlet grille, the hot air discharged by the crossflow fan can be precisely guided, preventing the hot air from spreading inside the equipment and ensuring that all the hot air flows through the through holes to the air outlet grille, significantly improving the airflow utilization rate.

[0016] 3. By setting rotating grille blades, the crossflow fan can blow the grille blades to rotate and automatically open to form an air outlet channel when it is working. The rotation angle can be adjusted according to the size of the airflow, thereby realizing automatic control of the channel size. When heat dissipation is not required, the crossflow fan is turned off, and the grille blades are reset and closed by gravity or torsion spring, which can effectively block external dust, water vapor and other impurities from entering the equipment.

[0017] 4. Install filters on the inner or outer side of the air inlet grille or on one side to filter the outside air entering the equipment, preventing dust, particulate matter and other impurities in the air from entering the equipment. This combines heat dissipation and dust prevention functions, ensuring long-term stable operation of the equipment. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0025] A crossflow heat dissipation system for formic acid hydrogen production equipment, such as Figure 1 As shown, the device includes a formic acid hydrogen production equipment body 1, the outer shell of which is rectangular (the top cover of the outer shell is not shown in the figure). A first fixing plate 2 is provided on the side wall of the formic acid hydrogen production equipment body 1, and a second fixing plate 3 is provided on the side wall opposite to the first fixing plate 2, such as the left side wall and the right side wall, or the front side wall and the rear side wall. An air inlet grille 4 is provided on the first fixing plate 2, and an air outlet grille 5 is provided on the second fixing plate 3. The air inlet grille 4 and the air outlet grille 5 connect the interior of the formic acid hydrogen production equipment body 1 with the outside air. A crossflow fan 6 is installed on the air outlet grille 5 on one side inside the formic acid hydrogen production equipment body 1, with the air inlet of the crossflow fan 6 facing the interior of the formic acid hydrogen production equipment and the air outlet facing the air outlet grille 5.

[0026] The crossflow fan 6 actively extracts hot air from inside the equipment and directs it to the exhaust grille 5 for discharge. Simultaneously, it draws in cool outside air from the intake grille 4, effectively breaking the heat buildup problem in the enclosed cabinet and ensuring the internal temperature of the equipment remains stable within a suitable range. Furthermore, compared to installing the crossflow fan 6 on the intake grille 4, where the fan actively draws in outside air and blows it into the equipment, requiring the hot air to rely on "cold air compression + natural convection" to be discharged from the exhaust grille 5, insufficient discharge power can cause hot air to stagnate deep within the cabinet, creating localized high temperatures. In this embodiment, the crossflow fan 6 is installed on the exhaust grille 5, directly extracting hot air from inside the equipment and creating a slight negative pressure inside the cabinet. This allows the hot air to be discharged directly and quickly, breaking the heat buildup problem at its source.

[0027] like Figures 2 to 4As shown, the crossflow fan 6 is installed inside the air outlet grille 5, that is, on the side close to the interior of the formic acid hydrogen production equipment body 1. An air guide plate 7 is located on the side of the air outlet grille 5 inside the formic acid hydrogen production equipment body 1. The air guide plate 7 is located between the crossflow fan 6 and the air outlet grille 5, completely covering the inner area of ​​the air outlet grille 5. A through hole 8 is provided on the air guide plate 7, and the air outlet of the crossflow fan 6 communicates with the through hole 8. A bent portion 9 is provided on the edge of the air guide plate 7, integrally formed with the air guide plate 7. The bent portion 9 is arranged in a circle along the edge of the air guide plate 7, and is tightly fitted to the inner surface of the second fixing plate 3. The air guide plate 7 and the second fixing plate 3 are fixedly connected by clips or screws. The crossflow fan 6 is then installed and fixed on the air guide plate 7. Hot air is guided through the interior of the crossflow fan 6 and discharged from the air outlet. It is precisely guided to the air outlet grille 5 through the through holes 8 of the air guide plate 7, preventing the hot air from spreading disorderly inside the equipment. At the same time, the sealing fit of the bend 9 can prevent hot air from leaking from the gap between the air guide plate 7 and the second fixed plate 3, significantly improving the airflow utilization rate and heat dissipation efficiency, and ensuring that all hot air is discharged to the outside of the equipment in a directional manner.

[0028] The air inlet of the crossflow fan 6 is located at the bottom of the fan itself, facing the lower interior space of the formic acid hydrogen production equipment body 1. The air outlet is horizontally located on the side wall near the air outlet grille 5, and is precisely aligned with the pre-set through hole 8 on the air guide plate 7. When the crossflow fan 6 is working, the bottom air inlet can efficiently draw in the rising hot air from the lower interior area of ​​the formic acid hydrogen production equipment body 1.

[0029] The air outlet grille 5 specifically includes an outer frame with several grille blades arranged vertically along the frame. Each grille blade is rotatably connected to the two side borders of the outer frame via cylindrical pivots. In its natural state (when the crossflow fan 6 is not operating), the grille blades maintain a nearly vertical closed state under their own gravity, blocking the air outlet channel of the air outlet grille 5. When the crossflow fan 6 blows the grille blades, the grille blades rotate horizontally to form an air outlet channel. When the fan stops operating, they automatically return to their original position due to gravity. This design allows for "on-demand opening and automatic closing" of the grille blades without additional control components. Furthermore, the greater the airflow pressure, the larger the rotation angle of the grille blades, and the wider the air outlet channel. The opening size is dynamically controlled according to the airflow volume, ensuring that airflow is not obstructed during heat dissipation while preventing external dust, moisture, and other impurities from entering the equipment through the air outlet grille 5 when the equipment is stopped, thus meeting the protection requirements of a closed cabinet. In other embodiments, the grille blades can also be reset by setting a torsion spring. A torsion spring is sleeved on the rotating shaft of the grille blades. In the initial state, the grille blades are in a closed state. The horizontal outward thrust generated by the crossflow fan 6 overcomes the spring force of the torsion spring and causes the grille blades to rotate outward around the rotating shaft to open the air outlet channel. When the equipment stops, the grille blades are reset by the torsion spring.

[0030] A filter screen (not shown in the figure) is installed on the air inlet grille 4 on one side inside and / or the other side outside the formic acid hydrogen production equipment body 1. The filter screen's dimensions at least cover the outer surface of the air inlet grille 4. Before entering the formic acid hydrogen production equipment body 1, outside air must first flow through the filter screen. The filter screen can intercept dust, particulate matter, and other impurities in the air, preventing impurities from adhering to the surface of electrical components inside the equipment, preventing obstruction of heat dissipation or short circuits, or entering the catalytic reaction area. In this embodiment, a filter screen is installed inside the air inlet grille 4, and the filter screen is fixed to the air inlet grille 4 with screws, and can be removed for cleaning and replacement. Because the air inlet grille 4 has a filter screen, the grille blades of the air inlet grille 4 can be set to a fixed opening type.

[0031] The first fixing plate 2 and the second fixing plate 3 are integrally formed with the side wall of the formic acid hydrogen production equipment body 1, or the first fixing plate 2 and the second fixing plate 3 are added to the side wall of the formic acid hydrogen production equipment body 1 by fasteners. In this embodiment, the first fixing plate 2 and the second fixing plate 3 are integrally formed with the side wall of the formic acid hydrogen production equipment body 1, and are the crossbeam side plates of the equipment shell itself. Two air inlet grilles 4 and two air outlet grilles 5 are respectively arranged on the first fixing plate 2 and the second fixing plate 3. Crossflow fans 6 are respectively installed on the air outlet grilles 5, and the crossflow fans 6 extend along the length direction of the second fixing plate 3.

[0032] The first fixed plate 2 and the second fixed plate 3 are located at the top of the formic acid hydrogen production equipment body 1. The first fixed plate 2 and the second fixed plate 3 are provided with openings. The air inlet grille 4 and the air outlet grille 5 are respectively fixed at the openings. The air inlet grille 4 and the air outlet grille are at the same height, forming a horizontally oriented airflow channel, shortening the path of cold air from entry to exit, and forming a rapid convection circulation with the power of the crossflow fan 6.

[0033] The working process of this utility model is as follows:

[0034] When the formic acid hydrogen production equipment 1 is running, the crossflow fan 6 is powered on and starts. Its bottom air inlet draws in the hot air generated by the reaction and the heating of the electrical components inside the equipment, creating a slight negative pressure inside the equipment. Under the action of negative pressure, the cold air from the outside enters the equipment after being filtered by the filter screen of the air inlet grille 4. It flows horizontally through the reaction chamber and the electrical component area and absorbs heat. Then, the hot air is drawn in by the crossflow fan 6 and blown towards the air outlet grille 5 through the horizontal air outlet. The airflow drives the grille blades to rotate and form an air outlet channel. Finally, the hot air is discharged outside the equipment. After the equipment stops, the crossflow fan 6 stops working, the grille blades close automatically, and the filter screen continues to block external impurities.

Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
