Description

Technical Field

[0001] This utility model relates to the field of lens barrel heat dissipation technology, and in particular to a microchannel heat dissipation structure inside a lens barrel. Background Technology

[0002] The main reasons for the need for heat dissipation inside the lens barrel involve the stability of the optical system, material properties, and equipment lifespan maintenance. The lens barrel is usually made of metal and optical glass / resin materials, which have significantly different coefficients of thermal expansion. When the temperature changes, the expansion / contraction rates of the lens barrel and the lens are different, causing the lens to deform or even break under stress.

[0003] However, traditional lens barrels lack a dedicated structure for heat dissipation. When the internal temperature is too high, it can easily cause the lens inside the lens barrel to become unstable, affecting the normal use of the lens. For example, when outdoor photographers shoot in high temperatures for extended periods, if the lens barrel lacks effective heat dissipation, the internal temperature of the lens barrel can easily rise. Utility Model Content

[0004] This utility model discloses a microchannel heat dissipation structure inside a lens barrel, which aims to solve the technical problem that traditional lens barrels lack a dedicated structure for guiding heat dissipation, and when the internal temperature is too high, it can easily cause unstable installation of the lens inside the lens barrel, affecting the normal use of the lens.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A microchannel heat dissipation structure for the interior of an microscope tube includes a microscope tube body. Two ring-shaped casings are provided on the outer side of the microscope tube body. A heat dissipation guiding component is provided on the inner wall of each ring-shaped casing, and a heat insulation and ventilation component is also provided on the ring-shaped casing. The heat dissipation guiding component includes a copper ring disposed on the inner wall of the microscope tube. The inner wall of the microscope tube also has evenly distributed dispersion channels, the inner walls of which are all covered by copper sheets. The copper sheets are connected to the copper rings. Several sets of fins are provided on the outer wall of the copper rings. The fins are located inside the ring-shaped casings and are used in conjunction with the heat insulation and ventilation component.

[0006] By adopting the above technical solution, the set dispersion channel combined with the copper ring can fully guide the heat inside the lens barrel to be conducted to the fins through solid heat conduction. The fins located in the ring box can dissipate the guided heat with the help of the heat insulation and ventilation components. During this process, the copper ring is connected to the lens barrel, and the connection is completely covered by the copper ring, so it will not affect the optical structure inside the lens barrel.

[0007] As a further embodiment of this utility model: the heat insulation and ventilation assembly includes heat dissipation grids disposed on the outer walls of both sides of the ring-shaped box, and the air holes on the heat dissipation grids are connected to the interior of the ring-shaped box.

[0008] By adopting the above technical solution, the heat guided by the heat dissipation component will be dissipated through the holes on the heat dissipation grids on both sides of the ring box. The heat dissipation grids on both sides correspond to each other, which facilitates air convection and improves heat dissipation effect.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. Excellent heat dissipation effect: It adopts a solid heat conduction method, using materials with good thermal conductivity such as copper rings to orderly guide the heat inside the lens barrel. Combined with the external fin design, it fully dissipates the internal heat and ensures continuous use of the lens.

[0010] 2. The heat dissipation effect is guaranteed. By utilizing the heat insulation on the outside of the ring box and the air convection guidance on both sides, heat can be stably discharged, ensuring the heat dissipation effect.

[0017] 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.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A microchannel heat dissipation structure inside an endoscope barrel includes an endoscope barrel body 1. Two ring-shaped boxes 2 are provided on the outer side of the endoscope barrel body 1. A heat dissipation guiding component is provided on the inner wall of the ring-shaped box 2. A heat insulation and ventilation component is also provided on the ring-shaped box 2. The heat dissipation guiding component includes a copper ring 4 disposed on the inner wall of the endoscope barrel. The inner wall of the endoscope barrel is also provided with equally spaced dispersion channels 5. The inner wall of the dispersion channels 5 is covered with copper sheets. The copper sheets are connected to the copper ring 4. Several sets of fins 6 are provided on the outer wall of the copper ring 4. The fins 6 are located inside the ring-shaped box 2. The fins 6 are used in conjunction with the heat insulation and ventilation component.

[0019] Among them, the dispersion channel 5 is distributed in a curved shape on the inner wall of the lens barrel body 1, which increases the overlap space between the dispersion channel 5 and the inside of the lens barrel to a certain extent, resulting in higher heat dissipation efficiency.

[0020] Specifically, in this solution, by combining the set dispersion channel 5 with the copper ring 4, the heat inside the lens barrel can be fully guided to the fins 6 through solid heat conduction. The fins 6 located in the ring box 2 can dissipate the guided heat with the help of the heat insulation and ventilation components. During this process, the copper ring 4 is connected to the lens barrel, and the connection is completely covered by the copper ring 4, so it will not affect the optical structure inside the lens barrel.

[0021] The inner wall of the ring box 2 is provided with equally spaced inner support plates 7. There is a notch on the lens barrel body 1 between two adjacent inner support plates 7. The copper ring 4 is composed of a protrusion 401 and an inner ring 402. The fin 6 is located on the outside of the protrusion 401. The protrusion 401 is adapted to the notch. The inner ring 402 is located on the inside of the lens barrel body 1.

[0022] It should be noted that the heat guided by the inner ring 402 within the lens barrel body 1 can be guided to the fin 6 through the protrusion 401, thus guiding the heat out in an orderly manner.

[0023] Reference Figure 1 and Figure 2 In a preferred embodiment, the heat insulation and ventilation assembly includes heat dissipation grids 3 disposed on the outer walls of both sides of the ring box 2, and the air holes on the heat dissipation grids 3 communicate with the interior of the ring box 2.

[0024] Specifically, the heat guided by the heat dissipation component will be dissipated through the holes on the heat dissipation grids 3 on both sides of the ring box 2. The heat dissipation grids 3 on both sides correspond to each other, which facilitates air convection and has a good heat dissipation effect.

[0025] It is particularly important to note that the outer side of the ring box 2 is coated with heat-insulating paint, and the ring box 2 is also made of heat-insulating material. Both the heat-insulating material and the heat-insulating paint are designed to ensure that the ring box 2 is not affected by external heat and to ensure stable heat dissipation.

[0026] The heat dissipation grid 3 has a filter screen on its inner side, and the filter screen and heat dissipation grid 3 are designed to be detachable and assembled. The detachable and assembled filter screen and heat dissipation grid 3 are convenient for regular cleaning and ensure heat dissipation.

[0027] Working principle: During use, the heat inside the lens barrel body 1 is conducted to the copper ring 4 through multiple micro-dispersing channels 5. The copper ring 4 then guides the heat from the inner ring 402 to the protrusion 401, and then disperses it through the fins 6 on the protrusion 401. During this process, the pores on the heat dissipation grid plates 3 on both sides of the ring box 2 can increase air convection and carry away the internal heat.

[0028] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
