2. Description of Related ArtWith the rapid development of technology, the volume of electronic components tends to be decreased, and the density and performance of electronic components per unit area become increased. As a result, a total heat generation of the electronic component is yearly increased, and a traditional heat dissipating device cannot afford to dissipate the total heat generation quickly. If the heat generated by the electronic component is not removed efficiently, it will leads to an electronic ionization and a thermal stress situation of the electronic component, which reduces an overall stability and a service life of the electronic component. Accordingly, it is imperative to dissipate the heat generated from the electronic component to prevent an overheat situation thereof. In addition, constantly increasing the frequency and transmission speed of electronic components also results in serious situations of electromagnetic interference and electromagnetic wave spillover.
