The present disclosure relates to a technical field of handheld game consoles, and in particular to a heat sink for a handheld game console.
A handheld game console is also known as a portable game console, a portable gamepad, or a portable game console. Since the handheld game console is portable and brings entertainment for people in a short period of time (such as waiting for a bus, waiting in line), the handheld game console is favored by consumers. The handheld game console generates heat when the handheld game console is operated, and the heat is easy to accumulate in a housing of the handheld game console. If the heat is not dissipated in time, the handheld game console is always worked under a high temperature environment, which shortens service life of components inside the handheld game console. More seriously, even a whole machine of the handheld game console is burnt out, causing irreparable adverse consequences.
At present, there is also a heat sink externally placed on the handheld game console for reducing an internal temperature of the housing of the handheld game console. The Chinese patent No. CN201821348501.9 discloses a fan-type heat sink for a handheld game console. The heat sink is directly clamped on a one side of the handheld game console through clipping plates, and a heat sink body is arranged in a same plane with a display screen of the handheld game console. Because the heat sink has its own gravity and a certain included angle is formed between the handheld game console and a vertical plane, the handheld game console is easy to shake. As a result, the heat sink is hardly tightly clamped and is easily separated from the handheld game console. Therefore, how to provide a heat sink capable of being stably clamped and not prone to falling off from the handheld game console is a problem to be solved by those skilled in the art.
In view of this, the present disclosure provides a heat sink for a handheld game console. A heat sink housing is configured to be an inverted L-shaped structure, so that a long portion of the heat sink housing is attached to a rear side of the handheld game console body, and a short portion is attached to a front side of the handheld game console body. Therefore, the handheld game console body is clamped in a groove of the inverted L-shaped structure of the heat sink housing, thereby stably clamping the handheld game console body and effectively preventing the heat sink from falling off from the handheld game console body.
The present disclosure provides the heat sink for the handheld game console. The handheld game console comprises a handheld game console body and heat dissipating holes defined on one side of the handheld game console body. The heat sink comprises a heat sink housing, an air inlet defined on a surface of the heat sink housing, an air outlet defined on the surface of the heat sink housing, a heat dissipating fan arranged in the heat sink housing, and a circuit board arranged in the heat sink housing.
The air inlet is aligned and attached to the heat dissipating holes on the one side of the handheld game console body. The heat sink housing comprises a long portion, a short portion, and a groove located between the long portion and the short portion. The short portion is arranged adjacent to the groove. The groove is arranged adjacent to the long portion. The long portion, the groove, and the short portion are sequentially arranged to form an inverted L-shaped structure. The inverted L-shaped structure is snapped on the handheld game console body.
Furthermore, the groove comprises an inner side surface and an outer side surface. The inner side surface of the groove is attached to the one side of the handheld game console body. The heat dissipating holes are on the one side of the handheld game console body.
