Abstract

The present invention provides one kind main controller shielding structure capable of shielding electromagnetic wave and dissipating heat for Internet refrigerator. The structure includes framed casing to hold CPU; porous part in the casing to dissipate heat the CPU produces; protrudent digitated plate on the CPU to transmit heat the CPU produces directly to the casing. The digitated plate is made of metal material with high heat conducting performance. The present invention has excellent CPU heat dissipating effect.

Description

technical field [0001] The present invention relates to a refrigerator, and furthermore, relates to a heat dissipation and electromagnetic wave shielding structure (Protection against heat and EMI depreciating structure of main controller for internet refrigerator) of an Internet refrigerator: The heat generated by the central processing unit of the Internet refrigerator is dissipated. Background technique [0002] Referring to the accompanying drawings, a prior art Internet refrigerator will be described below. [0003] figure 1 A partial cutaway oblique view showing a prior art Internet refrigerator with a master controller. figure 2 A cross-sectional view of the internal structure of the main controller in the prior art is shown. [0004] As shown in the figure, a refrigerating chamber and a freezing chamber are formed inside the refrigerator, and the storage space is selectively opened and closed through doors 1, 1'. [0005] A display unit (display unit) 3 is provi...
