Description

CROSS-REFERENCE TO RELATED APPLICATION This application claims the priority benefit of China application serial no. 202411560331.0, filed on Nov. 4, 2024. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification. BACKGROUND Technical Field The disclosure relates to an electronic device, and more particularly to an electronic device with a heat dissipation effect. Description of Related Art Head-up display (HUD) is the mainstream for future car cabin display. The high brightness specifications of the head-up display create a high temperature environment, which may cause damage or melting of components in severe cases. Furthermore, due to the high power operation of the head-up display and exposure to sunlight, the panel may also experience serious overheating, which causes serious product failure. Therefore, how to reduce or control the impact of the heat of the head-up display on the display quality, safety, and reliability of the high power head-up display is still an important topic in the art. SUMMARY The disclosure provides an electronic device with a heat dissipation effect. According to an embodiment of the disclosure, an electronic device includes a panel, a protective plate, and a housing. The panel has a first surface and a second surface. The protective plate is disposed above the panel and has a third surface and a fourth surface. The housing includes a first side cover and a second side cover. The third surface of the protective plate is attached to the second surface of the panel, and there is a first channel between the panel and the first side cover, so that a first gas flow flows between the first surface and the first side cover. The fourth surface of the protective plate is close to the second side cover, and there is a second channel between the protective plate and the second side cover, so that a second gas flow contacts the fourth surface of the protective plate. Based on the above, in the embodiment of the disclosure, there is the first channel between the panel and the first side cover, so that the first gas flow may flow between the first surface of the panel and the first side cover, and there is the second channel between the protective plate and the second side cover, so that the second gas flow may contact the fourth surface of the protective plate. In this way, heat is taken away from upper and lower sides (or front and back sides) of the panel in an enveloping convection heat dissipation manner, so that the electronic device of the disclosure can achieve a uniform heat dissipation and temperature reduction effect.
