Description

Technical Field

[0001] The utility model relates to the technical field of optical cable detection, and more specifically, to a portable optical cable detection device. Background Art

[0002] Since fiber optic detection equipment usually needs to include heat-generating components such as control boards, lasers, power supplies, and display boards, it is necessary to ensure a certain level of heat dissipation performance, otherwise it may have an adverse effect on the operation of the fiber optic detection equipment. In addition, fiber optic detection equipment usually also has grating components. Grating components are sensitive to ambient temperature, so how to keep the grating components warm also requires attention. At present, the heat dissipation of fiber optic detection equipment usually requires the installation of heat absorbers and cooling fans inside the body. In addition, the air inlet and outlet channels need to be arranged accordingly to meet the cooling requirements of the heat-generating components. Such a heat dissipation solution leads to a complicated structure of the fiber optic detection equipment, which is not conducive to miniaturization design.

[0003] In view of this, it is necessary to provide a new heat dissipation solution. Utility Model Content

[0004] The utility model aims to overcome at least one defect of the above-mentioned prior art and provide a portable optical cable detection device for solving the problem of redundant heat dissipation structure.

[0005] The technical solution adopted by the utility model is to propose a portable optical cable detection device, including a heat-conducting housing, a display device, a laser transmitter, a first control board, a grating device and a power supply device;

[0006] The display device is provided in the heat-conducting housing, and the display device is thermally connected to the heat-conducting housing;

[0007] The laser emitter, the first control board, the grating device and the power supply device are all arranged inside the heat-conducting housing, the power supply device supplies power to the first control board, and the display device, the laser emitter and the grating device are all electrically connected to the first control board;

[0008] The laser emitter, the first control board, the grating device, and the power supply device are all thermally connected to the inner surface of the heat-conducting housing.

[0009] In this solution, the display device, laser emitter, first control board, grating device, and power supply device, which are heat-generating components, are all thermally connected to the heat-conducting housing. When the optical cable detection equipment is working, the heat generated by each heat-generating component is transferred to the heat-conducting housing. The heat-conducting housing then acts as an integral heat dissipation component, significantly increasing the heat exchange area between the heat-generating components and the external environment, thereby accelerating the cooling of the optical cable detection equipment. By using the heat-conducting housing as the heat-absorbing component of the optical cable detection equipment, this solution can meet the heat dissipation requirements of existing portable optical cable detection equipment and reduce the need for additional heat dissipation devices within the heat-conducting housing. This contributes to the miniaturization of the optical cable detection equipment and improves its portability. At the same time, since the cooling fan can be omitted, there is no need to set up air inlet and outlet ducts, making it easier to set up a closed housing and improving the protection performance of the internal structure.

[0010] Furthermore, the heat-conducting housing is an aluminum housing.

[0011] The aluminum housing of this solution has good thermal conductivity, can fully absorb the heat of the heat-generating components and fully exchange heat with the external environment, thereby improving the cooling efficiency of the optical cable detection equipment. The aluminum housing also has the advantages of being easy to obtain, low cost and lightweight, which helps to control costs and improve portability.

[0012] Furthermore, a fin structure is provided on the surface of the heat-conducting housing.

[0013] The fin structure of this solution can increase the surface area of ​​the heat-conducting shell, thereby improving the level of heat exchange with the external environment.

[0014] Furthermore, the display device includes a display portion and a second control board electrically connected to the first control board, wherein a portion of the display portion is exposed on the surface of the heat-conducting shell, and the second control board is arranged inside the heat-conducting shell and its position corresponds to the display portion, and the second control board is thermally connected to the heat-conducting shell.

[0015] The display unit of this solution makes it easy for operators to view detection data, and facilitates direct heat exchange with the external environment, thereby promoting heat dissipation. In addition, the second control board is the main heat dissipation component of the display device. Through a thermal connection with the heat-conducting housing, the heat of the second control board is transferred to the heat-conducting housing, thereby increasing the heat dissipation area and enabling direct heat exchange with the external environment, significantly improving the heat dissipation level.

[0016] Furthermore, it also includes a heat absorbing component thermally connected to the second control board, and the heat absorbing component is used to absorb heat emitted by the second control board.

[0017] Since the second control board and the display unit need to be set at a distance, the contact area between the second control board and the heat-conducting housing is limited. The heat absorption component of this solution can expand the heat dissipation area of ​​the second control board, so that the heat of the second control board is accelerated to the inside of the heat-conducting housing through the heat absorption component, and then heat is exchanged with the external environment through the heat-conducting housing, thereby promoting heat dissipation of the second control board.

[0018] Furthermore, a heat-conducting cavity is provided for enclosing the power supply device, and the heat-conducting cavity is thermally connected to the heat-conducting housing.

[0019] This solution uses a heat-conducting cavity to expand the heat exchange area between the power supply device and the heat-conducting housing, thereby promoting heat dissipation of the power supply device. In addition, the heat-conducting cavity also has a stabilizing limiting effect on the power supply device, which helps to improve the overall structural strength of the optical cable detection equipment.

[0020] Furthermore, the grating device includes a grating portion and a thermal insulation component, both of which are electrically connected to the first control board. The thermal insulation component wraps the grating portion, and the thermal insulation component is thermally connected to the inner surface of the heat-conducting shell.

[0021] In this solution, the grating portion is relatively sensitive to the working temperature, and the grating portion is insulated by the thermal insulation component to keep the grating portion at a suitable working temperature. Since the temperature fluctuates after the thermal insulation component and the grating portion exchange heat, the thermal insulation capacity fluctuates. By thermally connecting the thermal insulation component to the heat-conducting shell, the heat exchange area of ​​the thermal insulation component can be increased, thereby improving the heat exchange level with the external environment, so that the thermal insulation component can maintain good thermal insulation capacity for the grating portion.

[0022] Furthermore, the thermal insulation assembly includes an assembly shell, a thermal insulation member, and a first cooling fin electrically connected to the first control board, the grating portion is arranged inside the assembly shell, the thermal insulation member is arranged in the assembly shell and the thermal insulation member wraps the surface of the grating portion;

[0023] The first cooling fin is provided on the assembly shell, and the first cooling fin includes a first cooling surface and a first heat dissipation surface, the first cooling surface is thermally connected to the grating portion, the first heat dissipation surface is thermally connected to the surface of the assembly shell, and the surface of the assembly shell is thermally connected to the inner surface of the heat-conducting housing; or

[0024] The first cooling surface is thermally connected to the grating portion, and the first heat dissipation surface is thermally connected to the inner surface of the heat-conducting housing.

[0025] The temperature of the grating part usually rises during operation. In this solution, the first cooling surface of the first refrigeration plate cools the grating part, and the first heat dissipation surface increases the heat dissipation area by thermally connecting with the assembly shell or the heat-conducting shell, thereby accelerating the cooling, so that the first refrigeration plate can maintain a high cooling capacity for the grating part, ensuring that the grating part assembly shell is at a suitable operating temperature.

[0026] Furthermore, the insulation component also includes a second refrigeration fin, which is arranged on the assembly shell. The second refrigeration fin includes a second cooling surface and a second heat dissipation surface. The second heat dissipation surface is thermally connected to the grating portion, and the second cooling surface is thermally connected to the surface of the assembly shell, or the second cooling surface is thermally connected to the inner surface of the heat-conducting shell.

[0027] The second cooling plate of this solution heats the grating part through the second heat dissipation surface of the second cooling plate, and the second cooling surface increases the heat exchange area by being thermally connected to the assembly shell or the heat-conducting shell, so as to accelerate the cooling through the external low temperature, so that the second cooling plate maintains high working efficiency, thereby being able to keep the grating part at a suitable working temperature under low temperature conditions.

[0028] Furthermore, the heat preservation component further includes a buffer, and the buffer abuts against the grating portion.

[0029] The buffer member of this solution improves the stability of the grating portion when it is arranged in the thermal insulation component, so that the thermal insulation component can reliably wrap the grating portion, thereby maintaining good thermal insulation performance of the grating portion.

[0030] Furthermore, the heat preservation assembly further includes a first heat conducting member, one surface of the first heat conducting member is heat-conductingly connected to the grating portion, and the other surface of the first heat conducting member is heat-conductingly connected to the first refrigeration fin.

[0031] Furthermore, the heat preservation assembly further includes a second heat conducting member, one surface of the second heat conducting member is heat-conductingly connected to the grating portion, and the other surface of the second heat conducting member is heat-conductingly connected to the second cooling fin.

[0032] Compared with the prior art, the beneficial effects of the present invention are: 1) by using the heat-conducting shell as the mounting shell of the portable optical cable detection equipment, and thermally connecting the heat-generating display device, laser emitter, first control board, grating device, and power supply device to the heat-conducting shell, the heat-conducting shell serves as an integral heat-absorbing component, significantly increasing the heat dissipation area of ​​the heat-generating device, helping to reduce the need to set a heat dissipation device inside the mounting shell, and promoting the miniaturization and portability of the optical cable detection equipment; 2) the need for cooling and heating the grating part is met by the first cooling plate and the second cooling plate. In addition, the first cooling plate and the second cooling plate are directly or indirectly thermally connected to the heat-conducting shell, thereby significantly increasing the area for heat exchange with the external environment through the heat-conducting shell, prompting the grating part to maintain a suitable working temperature.

DETAILED DESCRIPTION

[0042] The drawings in this utility model are for illustrative purposes only and are not to be construed as limiting the scope of this utility model. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent the actual dimensions of the products. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0043] Example 1

[0044] like Figure 1-4 As shown, this embodiment provides a portable optical cable detection device, including a heat-conducting housing 100, a display device 200, a laser emitter 300, a first control board 400, a grating device 500 and a power supply device 600;

[0045] The display device 200 is disposed in the heat-conducting housing 100 , and the display device 200 is thermally connected to the heat-conducting housing 100 ;

[0046] The laser emitter, the first control board 400, the grating device 500, and the power supply device 600 are all disposed inside the heat-conducting housing 100. The power supply device 600 supplies power to the first control board 400. The display device 200, the laser emitter, and the grating device 500 are all electrically connected to the first control board 400.

[0047] The laser emitter 300 , the first control board 400 , the grating device 500 , and the power supply device 600 are all thermally connected to the inner surface of the heat-conducting housing 100 .

[0048] In practice, to balance cost control and portability, the thermally conductive housing 100 is constructed of aluminum. Furthermore, to further increase the heat dissipation area of ​​the thermally conductive housing 100, a fin structure 130 is provided on the surface of the thermally conductive housing 100. This enhances heat exchange with the external environment and improves the cooling efficiency of the heat-generating device. In practice, the fin structure 130 can be directly machined from the thermally conductive housing 100 to simplify the manufacturing process.

[0049] During operation, since the display device 200, laser emitter 300, first control board 400, grating device 500, and power supply device 600, which serve as heat-generating components, are all thermally connected to the thermally conductive housing 100, the heat generated by the optical cable detection device during operation is transferred to the thermally conductive housing 100. The thermally conductive housing 100 then acts as an integral heat dissipation component, increasing the area for heat exchange between the heat-generating components and the external environment, thereby promoting the overall heat dissipation of the optical cable detection device. By utilizing the thermally conductive housing 100 as a heat-absorbing component of the optical cable detection device, the present invention can meet the heat dissipation requirements of existing portable optical cable detection devices and reduce the need for additional heat dissipation devices within the thermally conductive housing 100, thereby contributing to the miniaturization of the optical cable detection device and improving its portability. It should be noted that the surface of the first control board 400 is insulated to prevent electrical conduction between the first control board 400 and the thermally conductive housing 100, ensuring a good thermal connection between the first control board 400 and the thermally conductive housing 100 while maintaining the normal operation of the optical cable detection device.

[0050] refer to Figure 1-4 To facilitate assembly, in some embodiments, the heat-conducting housing 100 includes an upper housing 110 and a lower housing 120 that are matched with each other. An upper mounting cavity is formed inside the upper housing 110, and a lower mounting cavity is formed inside the lower housing 120. Thus, the display device 200, the laser emitter 300, the first control board 400, the grating device 500, and the power supply device 600 are assembled in the upper mounting cavity and the lower mounting cavity in an orderly manner, thereby avoiding the horizontal size of the optical cable detection equipment being too large. In addition, the surfaces of the upper housing 110 and the lower housing 120 can be fully utilized to conduct heat conduction connections with different heat-generating devices, so that the heat-conducting housing 100 as a whole absorbs the heat emitted by each heat-generating device relatively evenly, thereby accelerating heat exchange with the external environment.

[0051] For ease of explanation, illustratively, in this embodiment, the display device 200 is disposed in the upper housing 110 , and the laser emitter 300 , the first control board 400 , the grating device 500 and the power supply device 600 are sequentially arranged in the lower mounting cavity.

[0052] refer to Figure 2 The display device 200 includes a display unit 210 and a second control board 220. The second control board 220 is electrically connected to the first control board 400. In order to facilitate the operator to view the detection information, the display unit 210 is arranged in the thermally conductive housing 100 and partially exposed on the surface of the thermally conductive housing 100. In this way, it is also convenient for the display unit 210 to directly exchange heat with the external environment, thereby improving the cooling rate of the display device 200. The second control board 220 is arranged inside the thermally conductive housing 100 and is located corresponding to the display unit 210. The second control board 220 is thermally connected to the thermally conductive housing 100.

[0053] For example, continue to refer to Figure 2The upper housing 110 has an opening 111, the display unit 210 is mounted on the opening 111, and the second control board 220 is disposed within the upper cavity. Specifically, the second control board 220 is thermally connected to the upper housing 110 on all sides. In some embodiments, a thermally conductive member such as thermally conductive silicone or a thermally conductive insulating sheet is placed between the second control board 220 and the thermally conductive housing 100 to enhance heat exchange between the two. It should be noted that the surface of the second control board 220 is insulated to prevent electrical conduction between the second control board 220 and the thermally conductive housing 100, ensuring proper operation of the optical cable testing equipment.

[0054] refer to Figure 2 、 4 , further comprising a heat absorbing member 230 connected to the second control board 220 for heat conduction, and the heat absorbing member 230 is used to absorb the heat emitted by the second control board 220. In a specific implementation, the heat absorbing member 230 is arranged on the surface of the second control board 220 facing away from the display unit 210. It is easy to understand that the heat absorbing member 230 can increase the heat dissipation area of ​​the second control board 220, so that the heat of the second control board 220 is accelerated to dissipate to the inside of the heat-conducting housing 100 through the heat absorbing member 230, and then the heat is transferred to the heat-conducting housing 100, and heat exchange is carried out with the external environment by means of the heat-conducting housing 100, thereby accelerating the cooling of the second control board 220. In a specific implementation, continue to refer to Figure 2 、 4 The heat absorbing member 230 has a fin structure 130 to increase the surface area, thereby accelerating the heat dissipation to the heat conducting housing 100, thereby accelerating the cooling of the second control board 220. In some embodiments, the end of the heat absorbing member 230 away from the second control board 220 further extends to be thermally connected to the heat conducting housing 100, combined with Figure 4 It is understood that the heat absorption member 230 can be extended to be thermally connected to the inner surface of the lower shell 120. At this time, it is only necessary to appropriately adjust the position of the first control board 400, or set an avoidance opening for the first control board 400, so that the heat generated by the second control board 220 can also be conducted to the lower shell 120 and dissipated to the external environment through the lower shell 120.

[0055] In some embodiments, in order to improve the heat transfer efficiency of the first control board 400, the first control board 400 is directly connected to the inner surface of the heat-conducting housing 100, for example, the first control board 400 is directly set on the inner surface of the lower housing 120. Furthermore, in order to improve the heat exchange performance, the space between the first control board 400 and the lower housing 120 can also be filled with heat-conducting silicone, heat-conducting insulating sheets and other heat-conducting parts. Figure 2-4The first control board 400 is arranged in the lower installation cavity. In order to reduce the occupied space, the first control board 400 is provided with an assembly groove 410 that runs through the upper and lower surfaces thereof. The assembly groove 410 is matched with the installation of the laser emitter 300. In this way, a part of the thickness of the laser emitter 300 overlaps with the thickness of the first control board 400, thereby reducing the thickness of the optical cable detection equipment. In specific implementation, the laser emitter 300 can be provided with a number of assembly grooves 410 according to specific needs, and the number of the assembly grooves 410 is matched with the laser emitter 300.

[0056] refer to Figure 3 In order to support the laser emitter 300, a first heat-conducting support member 121 is provided on the inner surface of the lower shell 120. The lower end of the first heat-conducting support member 121 is heat-conductingly connected to the lower shell 120, and the upper end of the first heat-conducting support member 121 supports the laser emitter 300. In a preferred embodiment, the first heat-conducting support member 121 and the lower shell 120 are integrally formed, for example, by directly convexly processing the surface of the lower shell 120, which can simplify the processing technology and ensure good thermal conductivity between the first heat-conducting support member 121 and the heat-conducting shell 100. Similarly, in order to improve the heat exchange performance, heat-conducting silica gel, heat-conducting insulating sheets and other heat-conducting members can also be filled between the laser emitter 300 and the first heat-conducting support member 121. At this time, in order to achieve surface connection between the first control board 400 and the heat-conducting shell 100, refer to Figure 3 A second heat-conducting support member 122 is provided on the surface of the lower shell 120 outside the first heat-conducting support member 121. The first control board 400 is supported on the second heat-conducting support member 122. In a preferred embodiment, the second heat-conducting support member 122 and the heat-conducting shell 100 are integrally formed, for example, by directly convexly processing the surface of the lower shell 120, which can simplify the processing technology and ensure good thermal conductivity between the second heat-conducting support member 122 and the heat-conducting shell 100. Figure 3 The second heat-conducting support member 122 has a hollow area 123 in the middle. The above-mentioned first heat-conducting support member 121 is arranged on the inner surface of the heat-conducting housing 100 within the hollow area 123. In addition, some electronic components are also provided on the first control board 400. The hollow area 123 allows an accommodation space to be provided between the first control board 400 and the inner surface of the heat-conducting housing 100 to accommodate the electronic components assembled on the first control board 400.

[0057] refer to Figure 4, a heat-conducting cavity 700 for enclosing the power supply device 600 is further provided, and the heat-conducting cavity 700 is heat-conductingly connected to the heat-conducting housing 100. In a specific implementation, the heat-conducting cavity 700 is formed by the first heat-conducting protrusion 710 on the upper housing 110 and the second heat-conducting protrusion 720 on the lower housing 120. Specifically, in order to improve the heat conduction performance, the first heat-conducting protrusion 710 is integrally formed with the upper housing 110, for example, by directly protruding downward on the surface of the upper housing 110. Similarly, the second heat-conducting protrusion 720 is integrally formed with the lower housing 120, for example, by directly protruding upward on the surface of the lower housing 120. For details, please continue to refer to Figure 4 The pair of first heat-conducting protrusions 710 and the pair of second heat-conducting protrusions 720 are positioned correspondingly. When the upper shell 110 and the lower shell 120 are assembled into the heat-conducting housing 100, the first heat-conducting protrusions 710 and the second heat-conducting protrusions 720 enclose a heat-conducting cavity 700. The heat-conducting cavity 700 increases the heat exchange area between the power supply device 600 and the heat-conducting housing 100, thereby promoting heat dissipation of the power supply device 600. In addition, heat-conducting silicone or other heat-conducting materials can be further filled between the heat-conducting cavity 700 and the power supply device 600 to improve the thermal conductivity between the power supply device 600 and the heat-conducting cavity 700. In a specific implementation, the power supply device 600 can be a charging power supply, a power conversion module, a dry cell battery module, etc.

When implementing the grating device 500, refer to Figure 5-7 The grating device 500 includes a grating portion 510 and a heat preservation component. The grating portion 510 is electrically connected to the first control board 400. The heat preservation component wraps the grating portion 510 and is heat-conductingly connected to the inner surface of the heat-conducting housing 100. In some embodiments, continue to refer to Figure 6 The insulation component includes an assembly shell, an insulation component 550, and a first cooling fin 570. The first cooling fin 570 is electrically connected to the first control board 400. The grating portion 510 is arranged inside the assembly shell. The insulation component 550 is arranged in the assembly shell and the insulation component 550 wraps the surface of the grating portion 510.

The first cooling surface is thermally connected to the grating portion 510, the first heat dissipation surface is thermally connected to the surface of the assembly shell, and the surface of the assembly shell is thermally connected to the inner surface of the heat-conducting shell 100. Alternatively, the first cooling surface is thermally connected to the grating portion 510, and the first heat dissipation surface is thermally connected to the inner surface of the heat-conducting shell 100. The assembly shell has good thermal conductivity, for example, a metal shell can be used. In specific implementation, refer to Figure 6In order to improve the packaging stability and thermal insulation of the grating part 510, the assembly shell includes a frame body 520 with upper and lower openings, and an upper sealing plate 530 and a lower sealing plate 540 are respectively provided on the upper and lower sides of the frame body 520. In specific implementation, the thermal insulation member 550 can be arranged between the grating part 510 and the upper sealing plate 530, and / or, the thermal insulation member 550 can also be arranged between the inner surface of the frame body 520 and the grating, and the first cooling plate 570 can be arranged between the grating part 510 and the lower sealing plate 540, so that the first heat dissipation surface can be connected to the lower sealing plate 540 surface to improve the heat transfer performance. Afterwards, the lower sealing plate 540 conducts the heat to the heat-conducting shell 100 and exchanges heat with the external environment, accelerating the cooling of the heat dissipation surface. In this way, the first cooling plate 570 can maintain a high cooling capacity for the grating part 510, ensuring that the assembly shell of the grating part 510 is at a suitable working temperature.

[0059] In a preferred embodiment, a heat conducting member 560, such as a heat conducting silica gel or a heat conducting insulating sheet, may be provided between the grating portion 510 and the first cooling fin 570, and / or between the first cooling fin 570 and the lower sealing plate 540, and / or between the lower sealing plate 540 and the heat conducting housing 100 to improve the heat transfer efficiency between the grating portion 510 and the heat insulation component, and / or between the heat insulation component and the heat conducting housing 100.

Specifically, for example, the buffer member can be disposed between the grating portion 510 and the upper sealing plate 530, and / or between the grating portion 510 and the inner surface of the frame 520. To simplify the structure, the buffer member can be implemented in the form of thermal insulation foam. Thus, simply disposing the thermal insulation foam between the grating portion 510 and the upper sealing plate 530 can provide both buffering and thermal insulation for the grating portion 510.

[0061] refer to Figure 8In some embodiments, the heat preservation assembly further includes a second cooling fin 580, which is electrically connected to the first control board 400.

In a specific implementation, in order to have a large contact area with the grating portion 510, the second cooling fin 580 and the first cooling fin 570 are respectively attached to different surfaces of the grating portion 510. For example, the first cooling fin 570 is disposed between the lower surface of the grating portion 510 and the lower sealing plate 540, while the second cooling fin 580 is disposed between the grating portion 510 and the inner surface of the frame 520. When the operating environment is a low-temperature condition, the second refrigeration fin 580 heats up the grating portion 510 through the second heat dissipation surface, and the second refrigeration surface conducts the cold energy to the assembly shell through a thermal connection with the assembly shell and further conducts it to the heat-conducting shell 100, so as to accelerate the cooling through the external low temperature, so that the second refrigeration fin 580 maintains a high working efficiency, thereby being able to keep the grating portion 510 at a suitable working temperature under low-temperature conditions.
