[0016] Embodiment:
[0017] As Figs. 1 to 3 Shown, a notebook computer radiator includes heat dissipation plate 1 and bottom plate, the heat dissipation plate 1 left and right two sides are equipped with support plate 7, the bottom plate includes two parallel limit plate 6, and the two limit plate 6 is connected through connecting rod 3, the support plate 7 lower end is rotationally connected with limit plate 6, the support plate 7 rear wall rotationally connected with fixed rod 4, and the fixed rod lower end movably connects limit plate 6, the heat dissipation plate 1 top is equipped with fin 8, and the fin 8 is integrally formed with heat dissipation plate 1, and the heat dissipation plate 1 is used to support notebook computer, and the fin 8 is in notebook computer outside, and the heat dissipation plate 1 inside is cavity structure, and the heat dissipation plate 1 cavity is through with fin 8 cavity, and the heat dissipation plate 1 cavity is equipped with liquid heat transfer medium.
[0018] The limit plate 6 front end is equipped with hook 2 preferably in this embodiment.
[0019] The limit plate 6 is equipped with a plurality of card slots 5, and the fixed rod 4 lower end is clamped in the card slot 5 preferably in this embodiment.
[0020] The liquid heat transfer medium is alcohol preferably in this embodiment.
[0021] The material of heat dissipation plate 1 and fin 8 is copper preferably in this embodiment.
[0022] Preferably, the cavity of the heat dissipation plate 1 and the cavity of the fin 8 are negative pressure cavities.
[0023] Working principle: the notebook computer is placed in front of the heat dissipation plate 1 and clamped on the clamping hook 2, and the fin 8 is outside the notebook computer. According to the inclination of the notebook computer, the fixing rod 4 is adjusted and clamped on the corresponding clamping groove 5 of the limiting plate 6. When the notebook computer is working, heat is absorbed by the heat dissipation plate 1, and then is transmitted to the alcohol in the cavity. The alcohol is more easily gasified under the condition of negative pressure. After the alcohol is gasified, the heat is taken away into the fin 8. Since the temperature of the fin 8 is far lower than that of the heat dissipation plate 1, the alcohol gas is liquefied into liquid in the fin 8 and flows back to the heat dissipation plate 1, so that the process of heat absorption and heat dissipation is completed. The alcohol repeats the cycle in liquid state and gaseous state to realize the heat dissipation and cooling of the notebook computer.
