By directly connecting the heat dissipation piece 200 with the display module 300, the heat conduction efficiency between the heat dissipation piece 200 and the display module 300 is improved, thereby improving the heat dissipation efficiency of the heat dissipation piece 200 on the display module 300, preventing the local temperature of the display module 300 from rising, and ensuring the stability of the temperature of the display module 300.

[0046] The instrument heat dissipation structure provided by the application can ensure normal operation of the instrument, and can ensure normal display of the liquid crystal screen of the instrument under sunlight or under a long-time opening working condition, without black screen, dead machine and other adverse hidden troubles.

[0050] In addition, the edge of the upper shell 140 is provided with a plurality of first connecting parts 141 spaced apart, and the edge of the lower shell 150 is provided with a plurality of second connecting parts 151 spaced apart, and the first connecting parts 141 are connected with the second connecting parts 151.

[0053] As shown in Figure 4 and Figure 6 In some embodiments of the application, the display module 300 includes a display screen 310 and a control board 320.

[0054] The control board 320 is arranged on the side of the display screen 310 facing the lower shell 150, and the control board 320 is connected with the display screen 310 to control the display surface 311 of the display screen 310 through the control board 320.

It can be understood that the air vent hole 131 communicates with the flow guide space through the first opening 321, so that the heat of the heat dissipation member 200 can be dissipated into the flow guide space, and the heat in the flow guide space can be dissipated to the outside of the shell 100 through the first opening 321 and the air vent hole 131, so as to reduce the temperature of the display module 300.

[0056] As shown in the drawings, Figure 6 In some embodiments of the present application, the heat dissipation member 200 is arranged on the side of the display screen 310 facing the control board 320. It can be understood that the heat dissipation member 200 is arranged between the display screen 310 and the control board 320 and has a spacing with the control board 320 to prevent the heat dissipation member 200 from transferring heat to the control board 320, so as to ensure the stability of the control board 320.

[0059] In this embodiment, the heat dissipation fins 220 are arranged perpendicularly to the heat dissipation plate 210.

By connecting the heat dissipation plate 210 and the display screen 310, the contact area of the heat dissipation plate 210 and the display screen 310 is increased, so as to improve the heat conduction efficiency. By arranging the plurality of heat dissipation fins 220 at intervals on the side of the heat dissipation plate 210 away from the display screen 310, the heat on the heat dissipation plate 210 is conducted away through the heat dissipation fins 220, so that the heat is conducted to the side away from the display screen 310, thereby improving the heat dissipation efficiency of the display screen 310.

[0061] In some embodiments of the present application, the number of heat dissipation members 200 is a plurality, and the plurality of heat dissipation members 200 are arranged at intervals on the side of the display screen 310 facing the control board 320. It can be understood that by increasing the number of heat dissipation members 200, the heat dissipation efficiency of the display screen 310 is improved, and the uniformity of heat dissipation of the display screen 310 by the heat dissipation member 200 is improved.

[0062] As shown in the drawings, Figure 3 In some embodiments of the present application, the control panel 320 is provided with at least one first opening 321, and the heat dissipation member 200 communicates with the air-permeable part 130 through the first opening 321.

[0063] It can be understood that the number of first openings 321 can be one, two or any number of values, which can be specifically set according to actual conditions.

[0064] In some embodiments, the number of first openings 321 provided on the control panel 320 is multiple, and the multiple first openings 321 are arranged at intervals. By increasing the number of first openings 321, the efficiency of heat on the heat dissipation member 200 being discharged to the outside of the installation space 110 through the first opening 321 and the air-permeable part 130 can be improved, so as to avoid the accumulation of heat in the installation space 110, thereby improving the heat dissipation efficiency.

[0065] In some embodiments, along the first direction, the first opening 321 is towards the air-permeable part 130, so that the heat on the heat dissipation member 200 can be directly discharged through the first opening 321 and the air-permeable part 130, thereby shortening the path of heat being discharged from the installation space 110 to the outside of the shell 100, and further improving the heat dissipation efficiency.

[0066] In some embodiments, the air-permeable part 130 is multiple, and the multiple air-permeable parts 130 are arranged at intervals. It can be understood that by increasing the number of air-permeable parts 130, the efficiency of heat being discharged in the installation space 110 can be effectively improved.

By increasing the number of air-permeable holes 131, the air permeability of the air-permeable part 130, i.e. the heat dissipation efficiency of the air-permeable part 130, can be improved.

[0068] In this embodiment, the multiple air-permeable holes 131 are arranged at equal intervals to improve the uniformity of heat dissipation.

[0069] As shown in the drawings, Figure 3 and Figure 6 In some embodiments of the present application, the instrument heat dissipation structure includes a heat dissipation film 400 arranged on one side of the lower shell 150. The connection between the heat dissipation film 400 and the lower shell 150 includes adhesion or clamping, which can be specifically set according to actual conditions.

[0070] The edge of the heat dissipation film 400 is connected with the mouth wall of the second opening and covers the second opening, so as to ensure the stability of the connection between the heat dissipation film 400 and the lower shell 150.

[0071] It should be noted that the heat dissipation film 400 is a breathable film, which can conduct the heat generated by the display screen 310 during operation to the outside of the shell 100, and at the same time, the breathable film can ensure that the external water and steam do not enter the installation space 110, so as to ensure the stability and safety of the display module 300 in the installation space 110.
