After the liquid enters the drainage portion from the plurality of perforations, it can be discharged from the at least one first drain port, and due to the presence of the retaining wall, the liquid entering the drainage portion will not contact the electronic components, so damage to the electronic components can be effectively avoided. Various embodiments of the vehicle device of the present invention will be described in detail below.

[0050] Figure 1 FIG. 1 is a perspective schematic diagram of a vehicle device according to an embodiment of the present invention. Figure 2 2 is a perspective schematic diagram of an upper cover and a retaining wall according to an embodiment of the present invention. Figure 3 FIG. 1 is a schematic perspective view of a vehicle device (the upper cover is not shown) according to an embodiment of the present invention. Figure 4 FIG. 4 is a perspective schematic diagram of a heat dissipation element according to an embodiment of the present invention. Figure 5 FIG is a cross-sectional view of a vehicle device according to an embodiment of the present invention. Figures 1 to 5 As shown, the vehicle device includes a heat sink 110, a retaining wall 120, at least one electronic component 130, a fan 140, and a top cover 150.

The drainage portion 111 is configured to receive the electronic component from the through hole of the upper cover (e.g., Figure 1 and Figure 2 The drain portion 111 has a fan receiving portion 1111, which is configured to receive a fan (e.g., Figure 3 The electronic component receiving portion 112 is configured to receive electronic components (such as the fan 140 shown). Figure 3 and Figure 5The heat sink 110 is formed of a plurality of metals and is used to absorb heat generated by the electronic component 130 during operation and to help dissipate heat from the electronic component 130. In some embodiments, the heat sink 110 comprises metal. In some embodiments, the heat sink 110 is made of one or more metals.

[0052] like Figures 2 to 4 As shown, the retaining wall 120 separates the drainage portion 111 and the electronic component accommodating portion 112. In some embodiments, the retaining wall 120 separates the fan accommodating portion 1111 and the electronic component accommodating portion 112. In some embodiments, the retaining wall 120 is integrally formed with the upper cover 150 (e.g., Figure 2 As shown), or the retaining wall 120 and the heat sink 110 are integrally formed (not shown).

[0053] like Figures 3 to 5 As shown, the at least one electronic component 130 is disposed above the electronic component accommodating portion 112. Due to the presence of the retaining wall 120, the liquid entering the drainage portion 111 will not contact the electronic component 130, thereby effectively preventing the electronic component 130 from being damaged.

[0054] like Figure 3 and Figure 4 As shown, the fan 140 is disposed above the fan accommodating portion 1111. The fan 140 is configured to generate airflow to help the heat sink 110 dissipate heat.

In some embodiments, the liquid entering the fin portion 1112 or the fan housing portion 1111 can be blown to the drain by the airflow generated by the fan 140 and then discharged from the first drain port 150b. In some embodiments, the liquid (e.g., water) entering the fin portion 1112 or the fan housing portion 1111 can absorb the heat energy of the heat sink 110 and be converted into gas (e.g., water vapor). In some embodiments, as Figure 1 and Figure 2 As shown, the upper cover 150 further has at least one first ventilation opening 150c disposed above the at least one first drainage opening 150b for allowing the airflow generated by the fan 140 or the above-mentioned water vapor to be discharged.

[0058] In some embodiments, as Figures 3 to 5 As shown, the vehicle device further includes a cover plate 160 , which is disposed between the fin portion 1112 of the drain portion 111 and the upper cover 150 and covers the fin portion 1112 of the drain portion 111 , and a plurality of through holes 150 a are aligned with the cover plate 160 and the fan accommodating portion 1111 .
