In a specific implementation manner of this embodiment, the cross-sectional shape of the heat dissipation concave portion in the first direction is an inverted trapezoid, and the cross-sectional shape in the second direction is an upright trapezoid.

By adopting the scheme, the first part (bottom wall) of the heat dissipation concave part contacts the heating component, heat generated by the heating component is transferred to the first shell wall 3 (the second shell wall 4), the size is gradually increased, the heat absorption is stronger, more heat can be transferred, and the heat dissipation capacity is stronger.

In a specific embodiment of the present embodiment, the recess fins 34 do not (or not all) extend vertically away from the second housing wall 4, but extend at an angle. Preferably, the recess fins 34 on the side have the same curvature as the heat dissipation recesses, and the recess fins 34 on the intermediate position extend vertically in a direction away from the accommodating chamber.

In a specific implementation manner of this embodiment, the automobile host further includes: and the heat conducting sheet is clamped between the first part and the heating component.

By adopting the scheme, through setting up the conducting strip, not only can make the heat more even follow heating element conduct to the heat dissipation concave part on, can also play shock attenuation buffering's effect to the relative displacement of heat dissipation concave part and heating element, can also play certain sealed insulating effect in order to protect the important component on the circuit board.

In a specific implementation of this embodiment, the thermally conductive sheet is a thermally conductive silicone sheet.

The embodiment also provides an automobile, and the automobile host with the heat dissipation structure is adopted.

By adopting the scheme, the heat dissipation function of the automobile host is more excellent, the intelligent automobile host is further improved, the diversity of functions is positively improved, and the use experience of a user is improved.

The foregoing description is only illustrative of the preferred embodiment of the present utility model, and is not to be construed as limiting the utility model, but is to be construed as limiting the utility model to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the utility model, may be made by those skilled in the art without departing from the scope of the utility model.
