Technical Field

[0001] The utility model belongs to the technical field of heat dissipation devices, and particularly relates to a heat dissipation device for an optical transmission device of a vehicle-mounted radar. Background Technique

[0002] Optical transmission devices play a key role in vehicle-mounted radar systems, mainly responsible for efficiently and stably transmitting the data collected by radar sensors to the data processing center through optical fibers. Optical fiber transmission has the advantages of high bandwidth, low loss, and anti-electromagnetic interference, etc., which can ensure the accuracy and real-time performance of radar data. When the optical transmission device is operating, it needs to be cooled. When used in most regions, the heat dissipation structure can play a good role in cooling. However, when used in dusty and relatively hot regions such as deserts and plateaus, the effect of traditional heat dissipation devices needs to be further improved. Content of the Utility Model

[0003] The utility model provides a heat dissipation device for an optical transmission device of a vehicle-mounted radar, aiming to solve the problem that the heat dissipation effect of the current optical transmission device needs to be improved.

[0004] The utility model is realized as follows. A heat dissipation device for an optical transmission device of a vehicle-mounted radar includes a metal shielding case. An opening and a connecting plate are arranged at the top of the metal shielding case; a frame is installed on the connecting plate, and multiple groups of fans are evenly installed inside the frame. Air holes are evenly opened at the top and bottom of the frame, and a metal shielding net is installed at the top of the frame; wind grooves are equidistantly opened on the connecting plate within the range corresponding to the opening, and the openings of the wind grooves gradually decrease from top to bottom; limiting plates are installed at both the left and right ends of the connecting plate, and a limiting frame is installed at the top of the metal shielding case, and the limiting plates are slidably installed in the limiting frame.

[0005] Preferably, a groove is opened inside the limiting frame, and a pull rod is slidably installed in the groove. A clamping block is installed at the inner end of the pull rod, a spring is sleeved outside the pull rod, and a clamping groove adapted to the clamping block is opened at the upper end of the limiting plate.

[0006] Preferably, the limiting plate is slidably inserted into the limiting frame from front to back, and the front side of the clamping block is a slope.

[0007] Preferably, an embedded groove is opened at the top of the frame, and the metal shielding net can be bent and embedded into the embedded groove.

[0008] Preferably, two groups of fixing plates are symmetrically installed at the top edge of the frame. A fixing block is installed inside the fixing plates, and a pressing plate is installed between the two fixing blocks. The pressing plate is located at the center above the metal shielding net.

[0011] Preferably, a pull ring is installed at the upper end of the pressing plate.

[0012] Preferably, a notch adapted to the size of the fixing block is provided at the left edge of the fixing plate.

[0013] Compared with the prior art, the present application mainly has the following beneficial effects:

[0014] By equidistantly arranging air grooves on the surface of the connecting plate, the blown air flow can be evenly diffused into the interior of the metal shielding shell, so that the heat dissipation is more uniform and rapid. By reducing the bottom opening of the air grooves, the air flow can be compressed and blown towards the metal shielding shell. Through this setting, the air flow can be made faster, thereby promoting the temperature reduction and improving the heat dissipation effect of the metal shielding shell; in addition, the present utility model can achieve a good electromagnetic shielding effect.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the description of this application in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the description of this application and the above drawings are intended to cover non-exclusive inclusion.

[0024] Referring to "embodiments" herein means that specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0025] An embodiment of the present utility model provides a heat dissipation device for an in-vehicle radar optical transmission device, as Figures 1-5 shown, including a metal shielding case 1, an opening and a connection plate 2 are provided at the top of the metal shielding case 1; a frame 3 is installed at the upper end of the connection plate 2, and a plurality of groups of fans 4 are evenly installed inside the frame 3. Exemplarily, as Figure 1 shown, two groups of fans 4 are provided, and the two groups of fans 4 are symmetrically installed inside the frame 3; air holes are evenly opened at the top and bottom of the frame 3, and a metal shielding net 5 is installed at the top of the frame 3; air ducts 6 are equidistantly opened in the range of the connection plate 2 corresponding to the opening, and the openings of the air ducts 6 gradually decrease from top to bottom; limit plates 7 are installed at both the left and right ends of the connection plate 2, and a limit frame 8 is installed at the top of the metal shielding case 1, and the limit plates 7 are slidably installed in the limit frame 8.

[0026] When the device is in use, external air is inhaled into the metal shielding case 1 through starting the fans 4 for heat dissipation. After the fans 4 are started, the air will be blown into the air ducts 6. Since the air ducts 6 are equidistantly distributed above the metal shielding case 1, the blown air flow will evenly diffuse into the metal shielding case 1, so that the heat dissipation is more uniform and rapid. By reducing the bottom opening of the air ducts 6, the air flow can be compressed and blown towards the metal shielding case 1. Through this setting, the air flow can be made faster, and thus the temperature reduction can be promoted, so as to improve the heat dissipation effect of the metal shielding case 1.

[0027] Through the design of the metal shielding case 1 and the metal shielding net 5, the utility model can effectively improve the electromagnetic shielding effect and prevent optical transmission devices such as optical fiber amplifiers from being externally electromagnetically interfered.

[0028] Furthermore, for example, an air outlet is provided at the bottom of the metal shielding case 1.

[0029] In one embodiment, a groove is formed inside the limiting frame 8, and a pull rod 9 is slidably installed in the groove. A clamping block 10 is installed at the inner end of the pull rod 9, a spring 11 is sleeved outside the pull rod 9, and a clamping groove adapted to the clamping block 10 is formed at the upper end of the limiting plate 7. By providing the limiting plate 7 and the limiting frame 8, the limiting plate 7 is installed inside the limiting frame 8 in a sliding and clamping manner, and the clamping block 10 is snapped into the clamping groove of the limiting plate 7 under the elastic force of the spring 11, so as to realize the overall fixation of the air duct 6 and the frame 3. This connection method enables the air duct 6 and the frame 3 to be removed from the upper end of the metal shielding case 1 as a whole, which is convenient for subsequent cleaning and maintenance. At the same time, this installation method makes its disassembly and assembly simple, convenient and fast.

[0030] As an example, the limiting plate 7 is slidably inserted into the limiting frame 8 from front to back, and the front side of the clamping block 10 is set as an inclined surface. This setting enables the limiting plate 7 to push the clamping block 10 upward during installation, making it more convenient during installation.

[0031] Furthermore, an embedded groove is formed at the top of the frame 3, and the metal shielding net 5 can be bent and embedded into the embedded groove.

[0032] In one embodiment, two groups of fixing plates 12 are symmetrically installed at the top edge of the frame 3. A fixing block 13 is installed inside the fixing plate 12, and a pressing plate 14 is installed between the two fixing blocks 13. The pressing plate 14 is located at the center above the metal shielding net 5. By installing the metal shielding net 5 externally, it is convenient to remove it for cleaning. By providing the pressing plate 14 to limit the metal shielding net 5, the metal shielding net 5 can be pulled outwards by bending.

[0033] Furthermore, a sliding groove is formed inside the fixing plate 12, and the fixing block 13 is slidably embedded in the sliding groove of the fixing plate 12.

[0034] Furthermore, a brush 15 is installed on the lower surface of the pressing plate 14, and the brush 15 is attached to the outer surface of the metal shielding net 5.

[0035] By providing the brush 15, the pressing plate 14 can slide above the metal shielding net 5 along with the fixing block 13. When sliding, the brush 15 at the bottom of the pressing plate 14 can scrape and clean the upper surface of the metal shielding net 5. Through this setting, the convenience of cleaning the metal shielding net 5 can be improved.

[0036] In addition, a pull ring 16 can also be installed at the upper end of the pressing plate 14.

[0037] Further, a notch adapted to the size of the fixing block 13 is formed at the left edge of the fixing plate 12. Through this setting, the pressing plate 14 and the fixing block 13 can be removed as a whole, facilitating subsequent cleaning or replacement of the brush 15.
