Background

Electronic devices, especially notebook computer products, have become an effective means for improving market competitiveness due to miniaturization and lightness. Miniaturization, lightness and thinness will lead to the continuous increase of the heat flux density (heat generation per unit volume) of the equipment volume. Particularly, in the process of running large-scale computing software or large-scale games by equipment, the heating power of the equipment is increased sharply, so that the running speed of the equipment is reduced, and the phenomenon of pause appears; sometimes, the hand feeling experience of a user in the use process is poor due to the fact that the temperature of the shell of the device is high.

Aiming at the problems encountered by the current notebook products, a common solution is to externally adopt an air-cooled notebook cooling frame. The air-cooled notebook heat dissipation frame blows air to the bottom of the notebook from the environment, and has two functions: 1. the air inlet wind resistance of the notebook computer cooling system is reduced; 2. and carrying out forced air cooling heat dissipation on the bottom shell of the notebook computer. The air-cooled notebook computer radiating frame has a good auxiliary radiating effect, but the air-cooled notebook computer radiating frame cannot reduce the temperature of air blown to the bottom of a notebook computer, and even the temperature of the air is increased (when the air passes through a fan, the air is heated by the fan). Especially, when the ambient temperature is high and the system heat is large, the effect of the air-cooled notebook computer radiating frame is limited.

For overcoming the problem that air-cooled notebook heat dissipation frame air-out temperature receives ambient temperature to influence, reduce the influence of environment to the system heat dissipation, the utility model discloses a can refrigerated notebook heat dissipation frame. The appearance structure of the device is similar to that of an air-cooled notebook heat dissipation frame, but a fan is not used for blowing and dissipating heat of the notebook, and a refrigeration system plate type evaporator module of the notebook is adopted for attaching to assist in heat dissipation of the notebook.
