Embodiment 1
[0022] Such as figure 1 , figure 2 As shown, an air-cooled and liquid-cooled combined heat dissipation device described in this embodiment includes a housing 1 having a surface capable of connecting with a heating element. Sandwich structure, the outer heat dissipation chamber 4 contains heat dissipation fluid 6, the inner heat dissipation chamber 2 has an open airflow channel communicating with the outside world, and a sealing cover 3 covers the outer heat dissipation chamber 4. The housing 1 is a hollow cylinder, and the hollow part is the inner heat dissipation cavity 2 . A plurality of air guide holes 5 are opened below the side wall of the housing 1 to form the inlets of the air flow passages and the air guide holes 5 are evenly distributed in the circumferential direction, and the outlets of the air flow passages are arranged on the upper surface of the housing 1 . The sealing cover 3 has a hollow ring structure and is stepped, and the stepped surface is in conflict w...
Embodiment 2
[0026] Such as Figure 4 , Figure 5 As shown, in the air-cooled and liquid-cooled combined heat dissipation device described in this embodiment, the outer heat dissipation cavity 4 is a hollow rectangular cavity, and the sealing cover 3 has a hole in the middle and is stepped. The surface is fastened to the open end of the outer heat dissipation chamber 4. The entrance of the inner heat dissipation chamber 2 is formed by an air guide groove, which is arranged on the connecting surface of the shell 1 and the heating element. This structure is suitable for heat sinks that do not prevent gas from flowing through the bottom of the housing 1 . As shown in the figure, the present invention can connect the LED substrate 9 with the rivet 8 on the lower surface of the casing 1, and then put the lampshade 7 on it. Both the LED substrate 9 and the lampshade 7 are provided with air-conducting through holes.
