In the process of using the face recognition device, heat generated by the chip 4 is firstly transferred to the rear shell 2 through the heat conducting component 5, and the rear shell 2 dissipates the heat so as to dissipate the heat; simultaneously, the air current that holds 6 internal fans of chamber 3 and blow out can accelerate the circulation of air speed that holds in the chamber 3 for near hot-air near chip 4 is at whole chamber 3 inner loop that holds and flows, thereby with the heat diffusion on chip 4 to preceding shell 1 and backshell 2 on, and conduct away the heat through preceding shell 1 and backshell 2, fan 6 and heat-conducting component 5 work together, guarantee better radiating effect.

The chip 4 includes a third surface 41, and the third surface 41 is attached to the first surface 51, so that the heat of the chip 4 is transferred to the heat-conducting member 5. Further, the third surface 41 and the first surface 51 have the same shape, and the area of the third surface 41 is smaller than or equal to the area of the first surface 51, that is, the first surface 51 covers the third surface 41, so that the bonding area between the third surface 41 of the chip 4 and the heat conducting member 5 is the largest, and the heat dissipation effect is ensured.

As shown in fig. 2, the heat conducting member 5 further includes a first protruding portion 53 surrounding the first surface 51, the chip 4 further includes a side wall connected to the third surface 41, the first protruding portion 53 is attached to the side wall, so that the chip 4 is accommodated in the groove-shaped space formed by the first surface 51 and the first protruding portion 53, and the arrangement is such that the side wall of the chip 4 can also transmit heat to the heat conducting member 5 through the first protruding portion 53, thereby increasing the heat conduction area between the chip 4 and the heat conducting member 5 and ensuring better heat dissipation effect. And the chip 4 is accommodated in the groove-shaped space, so that the chip 4 and the heat conducting component 5 are conveniently positioned, and the stability of the chip 4 can be further ensured.
