Benefits of technology

[0010]One objective of this invention is to provide a cooling module without using a cooling fan so that an electronic product incorporating such a cooling module can comply with the noise-free requirements. The cooling module has a first heat conduction plate, a second heat conduction plate and a heat conduction device. The first heat conduction plate is substantially disposed above at least one heat source without coming into contact with each other. The ...

Problems solved by technology

However, a cooling fan relies on the electric power for operation and usually generates undesired noise during the operation.
It is not suitable for electronic products having requirement for power or noise limitations.
Furthermore, because modern electronic products are becoming increasingly smaller, there may be insufficient space to accommodate a large cooling fan.
Even if some electronic products are free from such limitations, a cooling fan disposed therein often tends to fail after operation for a long period of time.
However, the natural heat dissipation of hot air through the heat dissipating holes...

Embodiment Construction

[0022]FIG. 1A illustrates an electronic apparatus, for example, a calculation processing apparatus. More particularly, the calculation processing apparatus is a point of sale (POS) apparatus 1a. One of the features of the POS apparatus 1a is that no cooling fan is used therein so that the noise caused by the fan can be effectively decreased and the maintenance is easy. The following description provides several embodiments of a cooling module of this invention when being used to provide effective heat dissipation in the POS apparatus 1a. However, as may be appreciated by those skilled in the art, the cooling module disclosed in this invention may also be applied to other different electronic apparatuses.

[0023]FIG. 1B depicts a heat-generating block of a circuit board 2 disposed inside the POS apparatus 1a. The block includes at least one electronic component. For instance, there are two electronic components 111, 112, which may be South Bridges, North Bridges, CPUs, memories or the ...

Abstract

A cooling module for using in a metal housing of a calculation processing apparatus is disclosed. The cooling module is adapted to cool at least one heat source inside the metal housing. The cooling module comprises a first heat conduction plate, a second heat conduction plate and a heat conduction device, wherein the first heat conduction plate covers the heat source, the second heat conduction plate connects to the metal housing, and the heat conduction device is adapted to connect the first heat conduction plate with the second heat conduction plate. After the heat generated by the heat source is absorbed by the first heat conduction plate, the heat is transmitted to the second heat conduction plate through the heat conduction device, and will be dissipated uniformly throughout the metal housing.
