Abstract
A portable heat dissipation device is provided for operation with various devices of different purposes for heat dissipation therefrom and includes an enclosure and an air flow generation device. The air flow generation device is set in a given chamber inside the enclosure to effect flowing of air, causing air to enter through an inlet opening defined in a top of the enclosure and forcing the air flowing out through an outlet opening defined in a front wall of the enclosure. The portable heat dissipation device, when applied to remove heat, provides high performance of heat dissipation and effectively extended time interval of operation to thereby extend the lifespan of the device.
Claims14
A portable heat dissipation device adapted to dissipate heat from a target electronic device, the portable heat dissipation device comprising:
- an enclosure, which defines at least one first air flowing opening and at least one second air flowing opening;
- a concave accommodating dock formed on the enclosure, having a first section and a second section correspondingly opposite to the first section;
- a pair of first conductive elements spaced each other and arranged at the first section on the concave portion of the fan module accommodating dock;
- a pair of second conductive elements spaced each other and arranged at the second section on the concave portion of the fan module accommodating dock;
- a direction-exchangeable air flow generation module, comprising:
- an assembly frame having a first end plate and a second end plate correspondingly opposite to the first end plate;
- a pair of conductive terminals spaced each other and arranged at the first end plate of the assembly frame;
- and
- a cross flow fan, which has a shaft supported between the first end plate and the second end plate of the assembly frame and a plurality of blades extending in an axial direction of the shaft and fixed to a circumference of the shaft;
- a driving source, which is mounted on the assembly frame and coupled to the shaft of the cross flow fan for rotating the blades, whereby the cross flow fan draws in air through the inlet opening and generates at the outlet opening an air flow that travels in a direction substantially perpendicular to the axial direction toward the target electronic device;
- and
- a fixing mechanism for fixing the direction-exchangeable air flow generation module in the concave accommodating dock of the enclosure;
- wherein the assembly frame of the direction-exchangeable air flow generation device having a first assembly position adapted to be mounted into the concave accommodating dock of the enclosure so that the conductive terminals on the assembly frame electrically contact the first conductive elements on the concave portion of the fan module accommodating dock, and the assembly frame of the direction-exchangeable air flow generation device having a second assembly position selectively adapted to be mounted into the concave accommodating dock of the enclosure so that the conductive terminals on the assembly frame electrically contact the second conductive elements on the concave portion of the fan module accommodating dock.
