[0031] Under existing technology, in order to improve the visual range and provide the driver with a rear view when the rear window is blocked, the rearview mirror is replaced with a screen. However, a PCB board and an IC module need to be installed in the screen. The IC module and the screen itself will generate heat. Since the rearview mirror is relatively narrow, the heat cannot be dissipated, which will cause the IC module temperature to be too high and the screen to be distorted.

[0032] In order to solve the above problems, Figs. 1-2 As shown, the utility model provides a streaming media rearview mirror, which includes a bracket 1, a display screen module 2 is installed on one side of the bracket 1, and a shell 3 is installed on the other side of the bracket 1. The shell 3 and the bracket 1 form a mounting cavity, and a PCB board 4 is installed on the side of the bracket 1 close to the shell 3. A radiator 6 is installed in the mounting cavity, and the radiator 6 abuts against the IC module 5 on the PCB board 4. The streaming media rearview mirror of the utility model is usually installed on the front windshield in the vehicle cab, a positioning hole is formed on the PCB board 4, and a positioning protrusion is formed on the bracket 1. The positioning protrusion is inserted into the positioning hole, so that the PCB board can be installed on the bracket 1, and the heat generated by the display screen module 2 can be transferred to the bracket 1 and dissipated through contact with the outside air through the bracket 1.

[0033] A radiator 6 is installed on the other side of the bracket 1. Since the radiator 6 is in contact with the IC module 5 on the PCB board 4, the heat generated by the IC module 5 will be directly introduced into the radiator 6, increasing the contact area with the air, so that the heat of the IC module 5 can be quickly released into the air, reducing heat accumulation, and thus reducing the probability of a black screen or damage to the streaming media rearview mirror.

[0034] The protruding part 61 is formed on one side of the heat sink 6, and the heat-conductive silica gel 7 is attached to the protruding part 61 and abuts against the IC module 5. By arranging the protruding part 61, the heat-conductive silica gel 7 can be pressed during assembly, and the heat-conductive silica gel 7 can press the IC module 5 through the separately arranged protruding part 61, so that the heat-conductive silica gel 7 is more tightly attached to the IC module 5, the heat-conductive efficiency is improved, the heat generated by the IC itself can be efficiently and lowly conducted to the heat sink 6, the heat accumulation on the PCB 4 is reduced, the reliability of the streaming rearview mirror is higher, meanwhile, the protruding part 61 is not in contact with the PCB 4, and installation space is left for electronic elements on the PCB 4.

[0035] The heat sink 6, away from the IC module 5, is formed with a plurality of fins 62 away from one side of the PCB 4, and the contact area of the heat sink 6 and air is increased through the fins 62, so that the heat-conductive efficiency is higher, the heat generated by the PCB 4 and the display screen module 2 can be conducted to the other side of the mounting cavity of the support 1, the contact area with air is increased, and the heat-conductive capacity is improved.

[0036] The length direction of the PCB 4 is set as the X-axis direction, and the width direction of the PCB 4 is set as the Y-axis direction; a plurality of fins 62 are protrudingly arranged on the heat sink surface 63, the plurality of fins 62 are arranged at intervals, the fins 62 are parallel to each other, and gaps are formed between the fins 62 to allow airflow to pass through, so that the heat-conductive capacity is increased, meanwhile, gaps can also be arranged between each column of fins 62 to further increase the airflow flowing capacity, and the utility model adopts single-column fins 62, so that larger-area fins 62 can be formed in the mounting cavity, and the heat-conductive capacity is further improved.

[0037] Each fin 62 is perpendicular to the heat sink surface 63, so that the airflow between the fins 62 can flow freely, meanwhile, a gap is arranged between the end, away from the PCB 4, of the fin 62 and the inner wall of the shell 3, the gap is located in a set size range, so that the airflow can flow freely, and the heat-conductive capacity is increased.

[0038] The shell 3 is arc-shaped and semi-enclosed, along the X-axis direction of the PCB 4, the spacing between the high point of the inner wall of the shell 3 and the PCB 4 gradually increases from both ends to the middle along the X-axis direction, along the Y-axis direction of the PCB 4, the spacing between the high point of the inner wall of the shell 3 and the PCB 4 gradually increases from both ends to the middle along the Y-axis direction, and meanwhile, at least part of the fins 62 are in the shape of Chinese character Kuo to adapt to the arc-shaped inner wall of the shell 3.

[0039] In this way, the fin 62 height is lowered near the edge of the streaming rearview mirror, or the upper edge of the fin 62 is in the shape of a convex character, so that the fin 62 is adapted to the shape of the inner side of the shell 3 and a certain gap is left, avoiding the fin 62 from contacting the shell 3. The space on both sides of the fin 62 is heated by the heat on the fin 62. After the air on both sides of the fin 62 is heated, it can flow across the gap between the fin 62 and the shell 3 to take away heat, increase the heat dissipation capacity of the fin 62, and at the same time enable the fin 62 to reach the maximum height in the mounting cavity, increase the contact area with the air, and improve the heat dissipation capacity. In other embodiments, the upper end of at least part of the fin 62 is similar in shape to the inner wall of the shell 3 corresponding thereto. For example, in order to adapt to the arc-shaped inner wall of the shell 3, the top end of the fin 62 is also arc-shaped.
