The present invention relates to a heat dissipating device, and more particularly to an innovative structural type revealer of a heat dissipating device having a reinforcing supporting structure.

According to the expansion of the scale and operational efficiency of some electronic and computer equipment, the thermal temperature generated during operation is greatly increased, and the corresponding heat sink structure setting must also be compared with the scale of amplification.

As mentioned in the previous paragraph, hot plate type heat dissipating devices are usually installed in electronic and computer equipment to solve the heat dissipation requirement of a large area. However, when the setting area of the hot plate is expanded to a certain extent, the assembly is performed. There are often some problems.

For example, because the hot plate is a hollow shell type, according to the rationality of the general mechanical design, when the area is enlarged, the height should be relatively increased to obtain better structural strength, but at present, many electronic and computer equipment are To achieve the thin design requirements, the height of the hot plate is often limited to a thin gauge (such as 3mm), but this will inevitably lead to a relatively weak structural strength of the hot plate, and in this configuration In the state, when the hot plate is locked on the substrate to which the heat source belongs, the bottom wall of the hot plate tends to be deformed by the reverse pressing of the preset bottom support frame, which may result in the original The height of the inner chamber of the relatively thin hot plate is thus greatly reduced or even disappeared, thus seriously affecting the heat dissipation performance that should be achieved by the preset.
