The invention provides a multifunctional radiating support for a laptop. The multifunctional radiating support comprises a base and a supporting plate. The supporting plate is connected with the basethrough a hinge. The supporting plate comprises a frame. The frame is in a concentric-square shaped. A reticular plate is fixedly connected to the inner side of the frame. Two rectangular mounting blocks are fixedly connected with the lower side of the reticular plate. Movable grooves with openings facing downwards are formed in the mounting blocks. Movable blocks are arranged in the movable grooves. The lower sides of the two movable blocks are fixedly connected with a mounting plate jointly. A plurality of radiating fans are evenly connected to the upper side of the mounting plate. The rightportion of the base and the right portion of the supporting plate are connected through an inclination angle adjusting device. The inclination angle adjusting device comprises a supporting base. Themultifunctional radiating support has the following beneficial effects that the movable blocks can move in the movable grooves and drive the mounting plate to move, thus, the positions of the radiating fans are changed, different areas of the laptop are radiated by the radiating fans, and the radiating effect is effectively improved.
