Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a heat-dissipating structure, and in particular to a heat-dissipating base for an electronic product.
2. Description of Prior Art
Currently, many kinds of electronic products are proposed and widely used in our daily life, such as notebook computers, laptop computers, personal digital assistants, digital video disks (DVD) and tablet computers (XPAD). In order to make these electronic products more and more compact, a heat-dissipating device installed inside the respective electronic products is required to have a much simpler structure to thereby reduce the volume of the whole electronic product. However, the heat-dissipating efficiency of such a compact heat-dissipating device may be insufficient, so that the heat generated by electronic elements of the electronic product cannot be dissipated quickly and efficiently. As a result, the electronic elements may be overheated or suffer damage due to the accumulated heat.
Usually, the electronic elements are located in the bottom of the electronic product. Accordingly, heat pipes, vapor chambers and fans may be provided in the bottom of the electronic product for better heat dissipation. Since the heat generated by the electronic elements may be accumulated in the bottom of the electronic product to negatively affect the performance and lifetime of the electronic elements, various auxiliary heat-dissipating devices are proposed to improve the heat-dissipating efficiency, such as a cooling pad or a cooling stand available in the market. The cooling pad or the cooling stand is configured to provide an airflow space under the bottom of the electronic product to thereby improve the heat-dissipating efficiency of the electronic product.
With the advancement of science and technology, many kinds of electronic products are developed, each having different size and profile. Further, each kind of the electronic products is required to be made more and more compact for easy carry and storage. However, the conventional cooling pad or cooling stand is usually made by a metal plate with a fixed volume. Thus, when a customer buys an electronic product, the user also has to buy a cooling pad or cooling stand exclusively designed for the electronic product. On the other hand, the conventional cooling pad or cooling stand cannot be folded for easy carry and storage.
In view of the above-mentioned problems, the present Inventor proposes a novel and reasonable structure based on his expert knowledge and deliberate researches.
