Abstract

A vehicle display device includes a housing mounted on a vehicle, an image display device provided in a housing section of the housing, and a heat sink provided at a position to contact the image display device, in which the housing has an opening that is open upward, the heat sink is attached at a position to separate the housing section and the opening from each other in the housing, and has a heat dissipation surface exposed from the housing through the opening, and a discharging flow path for discharging a liquid that has entered the opening to the outside of the housing is formed on the heat dissipation surface.

First claim

What is claimed is:

1 . A vehicle display device comprising:
a housing mounted on a vehicle; an image display device provided in a housing section of the housing; and a heat sink provided at a position to contact the image display device, wherein the housing has an opening that is open upward in a state where the housing is mounted on the vehicle, the heat sink is attached at a position to separate the housing section and the opening from each other in the housing, and has a heat dissipation surface exposed from the housing through the opening, and a discharging flow path for discharging a liquid that has entered the opening to an outside of the housing is formed on the heat dissipation surface.

2 . The vehicle display device according to claim 1 , wherein
the heat sink has a plurality of protrusions protruding from the heat dissipation surface, and the discharging flow path is formed as a groove-shaped portion between adjacent ones of the protrusions on the heat dissipation surface.

3 . The vehicle display device according to claim 2 , wherein
the housing has a discharge port that is an outlet for the liquid that has entered the opening, and the discharging flow path includes a rectification region that is a region between adjacent ones of the protrusions and a terminal end region that is a region disposed in the discharge port and including a terminal end of the discharging flow path.

4 . The vehicle display device according to claim 1 , wherein
in a state where the housing is mounted on the vehicle, the heat dissipation surface is inclined in such a manner that the terminal end of the discharging flow path faces downward with respect to a horizontal plane orthogonal to a vertical direction of the vehicle.

5 . The vehicle display device according to claim 2 , wherein
in a state where the housing is mounted on the vehicle, the heat dissipation surface is inclined in such a manner that the terminal end of the discharging flow path faces downward with respect to a horizontal plane orthogonal to a vertical direction of the vehicle.

6 . The vehicle display device according to claim 3 , wherein
in a state where the housing is mounted on the vehicle, the heat dissipation surface is inclined in such a manner that the terminal end of the discharging flow path faces downward with respect to a horizontal plane orthogonal to a vertical direction of the vehicle.
