Like this at the rear of guide part formation guide way, after the heat upwards dashes to the guide way in, the guide way leads the heat and lets the heat pass through the second louvre, and the heat scatters and disappears through first louvre from the second louvre, further improves the radiating effect.
Furthermore, reinforcing ribs are arranged among the guide part, the connecting plate and the fixing plate. Thus, the strength of the guide part can be improved, and the strength of the heat dissipation bottom plate can be improved.
Furthermore, the lower left corner and the lower right corner of the avoiding hole on the connecting plate are respectively provided with a resisting part, and the resisting parts extend forwards from the connecting plate and extend towards the avoiding hole. The resisting part is used for resisting the component.
Furthermore, a rib plate connected to the connecting plate is arranged between the resisting part and the fixing plate. This can improve the strength of the stopper portion.
Furthermore, a first connecting column is arranged in front of the connecting plate.
Furthermore, a second connecting column is arranged behind the guide part, and a third connecting column is arranged behind the blocking part.
Further, the cavity becomes larger from bottom to top. The air moves upwards after being heated, and the upper end of the cavity is large and the lower end of the cavity is small, so that the upper end of the cavity is favorable for the heat to move upwards, and the heat dissipation effect is further improved.
Furthermore, a positioning column is arranged on the connecting plate, and a positioning hole extending from back to front is formed in the positioning column.
