Description

Technical Field

[0001] This utility model relates to the field of graphene technology, and in particular to a graphene film cooling device. Background Technology

[0002] Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms arranged in a hexagonal honeycomb lattice with sp2 hybrid orbitals. Graphene has excellent optical, electrical, and mechanical properties and has important application prospects in materials science, micro-nano fabrication, energy, biomedicine, and drug delivery. It is considered a revolutionary material for the future.

[0003] After the graphene film is processed, it needs to be cooled and shaped. However, most existing cooling methods use fans, which takes a long time and has an insignificant cooling effect, resulting in low efficiency. Therefore, we propose a graphene film cooling device to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the low cooling efficiency of graphene film in the prior art, this utility model provides a graphene film cooling device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a graphene film cooling device, including a shell, in which a row of first guide tubes and a row of second guide tubes are provided, the first guide tubes are located above the second guide tubes, the first guide tubes and the second guide tubes are staggered, the two ends of the first guide tubes and the second guide tubes are rotatably connected to the shell, the ends of the first guide tubes and the second guide tubes are provided with rotary joints, adjacent two first guide tubes are connected to the rotary joints through air pipes to form a first S-shaped heat dissipation channel, adjacent two second guide tubes are connected to the rotary joints through air pipes to form a second S-shaped heat dissipation channel, each of the first guide tubes and the second guide tubes is provided with two rows of air holes, the two rows of air holes are symmetrical about the axis of the first guide tube or the second guide tube, the first guide tubes and the second guide tubes are provided with metal rollers, the first guide tubes are provided with magnetic strips above them for attracting the metal rollers, and a pump is provided on one side of the shell for connecting the first S-shaped heat dissipation channel and the second S-shaped heat dissipation channel.

[0006] The graphene film is S-shaped and wound around the first and second guide tubes. An air pump introduces cooling gas into each of the first and second guide tubes, which then exits through an outlet, cooling the graphene film as it passes through. The graphene film is always in contact with the upper side of the first guide tube and the lower side of the second guide tube. To prevent bulging of the graphene film caused by the cooling airflow exiting through the outlet, which would affect its quality, metal rollers are installed inside the first and second guide tubes. The metal roller in the second guide tube is always in the lower position due to gravity. When the outlet on the second guide tube rotates to the lower position, the metal roller blocks the outlet, preventing bulging of the graphene film. The metal roller in the first guide tube is always in the upper position due to the magnetic attraction of a magnetic strip. When the outlet on the first guide tube rotates to the upper position, the metal roller blocks the outlet, preventing bulging of the graphene film.

[0007] Furthermore, to facilitate the insertion of the graphene film, the magnetic strip is mounted on the connecting plate, and the housing has a waist-shaped hole arranged vertically. A bolt threaded into the waist-shaped hole and connected to the connecting plate is inserted into the waist-shaped hole. The vertical position of the magnetic strip is adjusted by the cooperation between the connecting plate and the waist-shaped hole. When the magnetic strip is close to the first guide tube, the magnetic force attracts the metal roller, keeping the metal roller always in the upper position of the first guide tube; when the magnetic strip is away from the first guide tube, it facilitates the insertion of the graphene film.

[0008] Furthermore, in order to ensure that the metal roller rolls stably within the first guide tube and the second guide tube, limiting rings are provided at both ends of the metal roller, and two limiting grooves that cooperate with the limiting rings are provided on the inner wall surfaces of the first guide tube and the second guide tube.

[0009] Furthermore, the upper end of the housing is provided with an air outlet, and a filter screen is provided at the air outlet.

[0010] Furthermore, the outer side of the housing is provided with multiple sets of heat dissipation fins.

[0011] The beneficial effects of this utility model are as follows: The graphene film cooling device provided by this utility model uses a graphene film in an S-shape wound around a first guide tube and a second guide tube. Cooling airflow is discharged through the air outlet to cool the graphene film at close range. A metal roller is attracted by a magnet to block the air outlet at the upper side of the first guide tube, and the air outlet at the lower side of the second guide tube is blocked by the gravity of the metal roller. When the graphene film is in close contact with the air outlet, the cooling airflow is prevented from impacting the graphene film and forming bulges, thus ensuring the quality of the graphene film.

[0017] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] like Figure 1-3 As shown, the present invention discloses a graphene film cooling device, comprising a housing 1, an air outlet at the upper end of the housing 1, and a filter 12 at the air outlet. Multiple sets of heat dissipation fins 13 are provided on the outer side of the housing 1.

[0019] The housing 1 is provided with a row of first guide tubes 2 and a row of second guide tubes 3. The first guide tubes 2 are located above the second guide tubes 3. The first guide tubes 2 and the second guide tubes 3 are staggered. The two ends of the first guide tubes 2 and the second guide tubes 3 are rotatably connected to the housing 1 through bearings. The first guide tubes 2 and the second guide tubes 3 rotate synchronously through a synchronous belt. A motor is driven to any second guide tube 3 so that the rotation speed of the first guide tubes 2 and the second guide tubes 3 matches the feeding speed of the graphene film. The first guide tube 2 and the second guide tube 3 are provided with rotary joints 4 at their ends. The rotary joints 4 are connected between two adjacent first guide tubes 2 through air pipes 5 to form a first S-shaped heat dissipation channel. The rotary joints 4 are connected between two adjacent second guide tubes 3 through air pipes 5 to form a second S-shaped heat dissipation channel. The first guide tube 2 and the second guide tube 3 are each provided with two exhaust holes 6. The two exhaust holes 6 are symmetrical about the axis of the first guide tube 2 or the second guide tube 3. The first guide tube 2 and the second guide tube 3 are provided with metal rollers 7. The first guide tube 2 is provided with a magnetic strip 8 above it for attracting the metal rollers 7. The housing 1 is provided with an air pump on one side for connecting the first S-shaped heat dissipation channel and the second S-shaped heat dissipation channel.

[0020] The magnetic strip 8 is disposed on the connecting plate 9, and the housing 1 is provided with a waist-shaped hole 10 arranged in the vertical direction. A bolt 11 that is threadedly connected to the connecting plate 9 is inserted into the waist-shaped hole 10.

[0021] The metal roller 7 is provided with limiting rings 71 at both ends, and the inner wall surfaces of the first guide tube 2 and the second guide tube 3 are provided with two limiting grooves 21 that cooperate with the limiting rings 71.

[0022] Work process:

[0023] Before powering on, adjust the position of the connecting plate 9 so that the magnetic strip 8 is away from the first guide tube 2. Wrap the graphene film in an S-shape around the first guide tube 2 and the second guide tube 3. Then adjust the position of the connecting plate 9 again so that the magnetic strip 8 is close to the first guide tube 2, ensuring that the metal roller 7 is always attracted by the magnetic strip 8 and positioned above the first guide tube 2. After powering on, the air pump introduces cooling gas into each of the first guide tubes 2 and the second guide tube 3. The cooling gas is discharged from the air outlet 6, cooling the graphene film. The metal roller 7 in the second guide tube 3 is always positioned below due to gravity. When the air outlet 6 on the second guide tube 3 rotates to the lower position, the metal roller 7 blocks the air outlet 6, preventing the graphene film from bulging. The metal roller 7 in the first guide tube 2 is always positioned above the first guide tube 2 due to the magnetic attraction of the magnetic strip 8. When the air outlet 6 on the first guide tube 2 rotates to the upper position, the metal roller 7 blocks the air outlet 6, preventing the graphene film from bulging.
