Patent ID: 8730663

Claim:
An electronic apparatus, comprising: a housing, configured with a plurality of inlets and one outlet, the inlets being provided for guiding a cooling air to flow into the housing; a plurality of electronic elements, disposed inside the housing; and a plurality of gates, arranged at positions corresponding to the plural inlets; wherein, the plural electronic elements are enabled to achieve their respective working temperatures while being activated, and there are at least two of the plural electronic elements whose working temperatures are not the same; and when the electronic apparatus is enabled, the plural electronic elements are activated for causing the temperatures of the plural electronic elements to be raised to their respective working temperatures, thereby, causing a plurality of heating zones to be formed inside the housing at positions respectively corresponding to the plural inlets in an one-by-one manner while allowing each of the plural heating zones to contains at least one of the plural electronic elements; and each of the plural gates has one thermal expansion element configured thereat while allowing the thermal expansion element to deform with the temperature variation of the corresponding heating zone, and by the deformation of the thermal expansion element according to a temperature variation of the corresponding heating zone, each gate is enabled to move between a first position and a second position according to the deformation of the corresponding thermal expansion element; wherein each of the thermal expansion elements is made of a material exhibiting anisotropic thermal expansion behavior, and is capable of expanding/contracting in a single direction.
