[0033] like Figures 1 to 3 As shown, the heat dissipation device is used for heat dissipation of the tracker. The heat dissipation device includes a heat dissipation housing 100, a heat sink 200, and a cooling fan 300. The heat dissipation housing 100 has an air inlet 101 and an air outlet 102. The heat dissipation housing 100 can be fixed to the outer shell 10 of the tracker. The outer shell 10 contains electrical components that can generate heat. The heat sink 200 is disposed in the heat dissipation housing 100 and is thermally connected to the electrical components. The cooling fan 300 is fixed inside the heat dissipation housing 100. The cooling fan 300 is used to drive external air to flow from the air inlet 101 through the heat sink 200 and out of the air outlet 102 to the outside. The air inlet direction of the air inlet 101 is not parallel to the air outlet direction of the air outlet 102.

[0034] The heat dissipation device in the embodiment is used for heat dissipation of the tracking instrument. The heat dissipation shell 100 is directly fixed on the shell 10 of the tracking instrument. The shell 10 is internally provided with electrical elements of the tracking instrument. The electrical elements generate heat during use. The electrical elements are generally chips or modules with relatively large heat generation, such as CPU / GPU / projector, and the like. The heat dissipation shell 100 is internally provided with a heat radiator 200 and a heat dissipation fan 300. The heat radiator 200 is in heat transfer connection with the electrical elements and is used for guiding the heat generated by the electrical elements to the heat radiator 200. After the heat dissipation fan 300 is started, the air with low temperature outside is guided to flow from the air inlet 101 to the air outlet 102 of the heat dissipation shell 100. The air flow cools the heat radiator 200 and guides the heat on the heat radiator 200 to the outside of the heat dissipation device, thereby realizing reliable cooling of the tracking instrument. The heat dissipation device realizes integration of the tracking instrument and the heat dissipation device and can realize efficient cooling and heat dissipation of the tracking instrument, thereby improving the reliability and service life of the tracking instrument.

[0035] As shown in Figure 2 In the embodiment, the shell 10 is sleeved on the main beam 11 of the tracking instrument. The main beam 11 is provided with the electrical elements. Since the heat dissipation device is directly arranged on the shell 10 of the tracking instrument and is not arranged on the main beam 11 connected with the electrical elements, the vibration of the heat dissipation fan 300 of the heat dissipation device does not affect the operation of the electrical elements, thereby ensuring reliable operation of the tracking instrument.

[0036] As shown in Figures 3 to 5 Further, the heat dissipation shell 100 includes a main shell 110 and a fan cover plate 120. The main shell 110 is provided with a first mounting hole 111. The fan cover plate 120 can be mounted on the main shell 110 through the first mounting hole 111. The heat dissipation fan 300 is fixed on the inner side of the fan cover plate 120. The fan cover plate 120 is provided with the air outlet 102. In the embodiment, the fan cover plate 120 is detachably connected to the fan cover plate 120. Specifically, the fan cover plate 120 and the main shell 110 are fixedly connected in a buckling manner. The fan cover plate 120 can be detached. The heat dissipation fan 300 can be maintained and replaced, thereby ensuring efficient and reliable operation of the heat dissipation fan 300 and reliable cooling and heat dissipation of the tracking instrument by the heat dissipation device.

[0037] In the embodiment, the heat dissipation fan 300 and the fan cover plate 120 are provided with a buffer foam 121. The buffer foam 121 can reduce the vibration generated by the heat dissipation fan 300 during operation and affect the normal operation of the tracking instrument, thereby ensuring reliable operation of the tracking instrument and accuracy of the measurement results.

[0038] Specifically, the heat dissipation fan 300 is further provided with a dust screen 122. The provision of the dust screen 122 can prevent external sundries such as dust, sand and debris from entering the heat dissipation fan 300, thereby avoiding affecting the normal operation of the heat dissipation fan 300.

[0039] As shown in Figure 3 and Figure 6 The main housing 110 is further provided with a second mounting hole 112. The heat dissipation cover plate 130 is mounted on the main housing 110 through the second mounting hole 112. The heat dissipation cover plate 130 is provided with the heat sink 200. The heat sink 200 and the electrical element are filled with a heat-conducting medium. The heat dissipation cover plate 130 is provided with the air inlet 101. Specifically, the heat-conducting medium can be silicone grease or heat-conducting gel. The heat dissipation cover plate 130 is detachably connected with the second mounting hole 112, and is fixed in the second mounting hole 112 of the main housing 110 by buckling. By detaching the heat dissipation cover plate 130, the heat sink 200 can be maintained and replaced. The heat sink 200 is in heat-conducting connection with the electrical element through the heat-conducting gel, which can ensure sufficient contact between the heat sink 200 and the electrical element, achieve efficient heat-conducting connection, ensure the cooling effect of the electrical element, and ensure the reliable operation of the tracking instrument.

[0040] In the embodiment, the air inlet 101 includes an air inlet grille. The extension direction of the air inlet grille is perpendicular to the extension direction of the fins 210 of the heat sink 200. In the embodiment, the heat sink 200 includes a plurality of uniformly spaced fins 210. The fins 210 can increase the contact heat dissipation area with the airflow. The extension direction of the air inlet grille is perpendicular to the extension direction of the fins 210, which can ensure that the width of the air inlet 101 is consistent with the width of the heat sink 200, and ensure efficient heat dissipation of the heat sink 200 by the flowing air.

[0041] Further, the extension direction of the fins 210 of the heat sink 200 is parallel to the flow direction of the airflow flowing through the air inlet 101. Such a configuration can increase the contact area between the flowing airflow and the fins 210 of the heat sink 200, improve the cooling effect of the heat sink 200, ensure that the heat on the heat sink 200 is fully dissipated, and further improve the cooling effect of the electrical element.

[0042] As a preferred embodiment, along the extension direction of the fins 210, the air inlet 101 and the air outlet 102 are arranged at two ends of the heat sink 200. Such a configuration can completely cover the fins 210 of the heat sink 200 when the air flows through the air inlet 101 and the air outlet 102, thereby achieving sufficient cooling of the heat sink 200 and improving the cooling and heat dissipation effect of the heat dissipation device.

[0043] The utility model also provides a kind of tracker, and the tracker includes the heat sink as any of the above scheme described.The tracker uses the heat sink described above, can realize the integration of heat sink and tracker, can simultaneously carry out efficient cooling and heat dissipation to the internal electrical components of tracker, and will not affect the normal operation of electrical components and tracker, improve the operation reliability and service life of tracker.
