[0002] There are many types of sensors, including: temperature sensors, wind direction sensors, wind speed sensors, humidity sensors, acceleration sensors, etc.

[0003] Among them, the wind speed sensor is a device used to measure wind speed, which uses the force of wind and the change of wind pressure to measure wind speed. Its structure includes wind cup, central axis, supporting structure, etc.

[0004] However, when the wind speed sensor is used in an outdoor environment, the wind cup of the wind speed sensor will generally be affected by the wind and rotate continuously. At this time, the inner ring of the central axis will rotate continuously. However, the long-term rotation of the central axis will generate heat. When the central axis is affected by long-term heat, it may deform, eventually causing the movement trajectory of the wind cup to change, thus affecting the wind speed measurement of the wind speed sensor;

[0031] The bracket 3 is provided with a heat dissipation structure 8 for dissipating heat from the central axis 4. The heat dissipation structure 8 includes a heat dissipation channel 801 provided in the bracket 3 and a heat-conducting ring 802 located below the central axis 4.

One end of the U-shaped heat-conducting sheet 804 away from the heat-conducting ring 802 is located in the heat dissipation channel 801. According to the above technical solution, specifically, first, the outside wind will enter the heat dissipation channel 801. Since the heat dissipation channel 801 is connected to the outside at multiple locations, when When the wind direction changes, the wind can still enter the heat dissipation channel 801. At this time, the wind entering the heat dissipation channel 801 is used to cool down the area of ​​the inner wall of the bracket 3 close to the central axis 4, thereby cooling down the outer wall of the central axis 4. Secondly, the wind entering the heat dissipation channel 801 blows toward one end of the U-shaped heat conductive sheet 804, which is used to cool down the U-shaped heat conductive sheet 804, and then cool down the heat conductive ring 802. At this time, the thermal conductive beads 803 are also cooled accordingly.

[0032] Reference Figure 2 and Figure 3 A plurality of U-shaped heat conducting sheets 804 are provided, and one end of each U-shaped heat conducting sheet 804 is connected to the bracket 3 . The plurality of U-shaped heat conducting sheets 804 are used to ensure the heat dissipation capability and support the heat conducting ring 802 .

[0033] Reference Figure 4 A dust shield assembly 9 is provided on the outer shell 2, and the dust shield assembly 9 includes a filter screen 902 and an L-shaped plate 904 detachably mounted on the outer shell 2. An installation groove 901 connected to the heat dissipation channel 801 is opened on the outer shell 2, and screws 903 are installed on the filter screen 902.

[0035] Working principle:

[0036] The sensor with heat dissipation effect will enter the heat dissipation channel 801 through the external wind. Since the heat dissipation channel 801 is connected to the outside world at multiple locations, the wind can still enter the heat dissipation channel 801 when the wind direction changes. At this time, the wind entering the heat dissipation channel 801 is used to cool down the area of ​​the inner wall of the bracket 3 close to the central axis 4, thereby cooling down the outer wall of the central axis 4. Secondly, the wind entering the heat dissipation channel 801 blows toward one end of the U-shaped heat conductive sheet 804, which is used to cool down the U-shaped heat conductive sheet 804, and then cool down the heat conductive ring 802. At this time, the heat conductive beads 803 are also cooled accordingly. Finally, it is used to cool down the inner ring of the central axis 4, thereby achieving the effect of cooling down the central axis 4, which helps to prevent the central axis 4 from being deformed due to long-term heat influence and affecting the wind speed sensor's measurement of wind speed.

[0037] The sensor with heat dissipation effect utilizes the filter 902 to block dust for the heat dissipation channel 801, and uses the external wind force to blow the sliding rod 906 and the blowing brush 907, and uses the wind direction and the change of wind direction to clean the dust on the filter 902, thereby achieving the effect of long-term effective dust blocking inside the heat dissipation channel 801 while ensuring that the wind can smoothly pass through the filter 902 into the heat dissipation channel 801.
