Heat dissipation device which is pre-built with an air vent structure
A heat dissipation device which is pre-built with an air vent structure uses primarily a plurality of cooling fins, which are formed into different lengths, to assemble into the heat dissipation devices of different shapes, for shunning away from other elements inside a computer host. In addition, diversion baffles of a different angle can be arranged and assembled, so as to form air ducts following an angle of wind direction, allowing an air flow to be smoothly guided in by a fan, and to quickly flow into a heat transmission zone in a gap between the cooling fins, such that a heat source can be dissipated more quickly.

a) Field of the Invention
The present invention relates to a heat dissipation device which is pre-built with an air vent structure, and more particularly to a heat dissipation device which is formed with all kinds of shapes by assembling cooling fins that are shaped in advance with different lengths, so as to avoid other structures and to form diversion baffles as air ducts for guiding an cold air flow.
b) Description of the Prior Art
To solve an over-heat problem of elements inside a computer host, usually a heat dissipation device is installed on an electronic heating element, such that heat generated from the electronic element can be dissipated by the heat dissipation device. However, for the conventional heat dissipation device, a base plate of a radiator is installed with cooling fins, and the base plate is tightly pressed on the electronic heating element, to dissipate heat energy from high temperature created when the electronic element is operating, through the cooling fins. Although this kind of heat dissipation device has a low cost, its heat conduction rate is slow, and hence is only suitable for a computer with a lower operation speed. As the heat dissipation effect is limited for the electronic heating element requiring to operate with a fast speed or for a long time, the conventional heat dissipation device is not perfect at all. Due to that the heat dissipation requirement has not been able to be satisfied by using only the cooling fins, an existing improvement mode is to use a heat dissipation device with a fan, which dissipates the heat energy by force convection.

Accordingly, the present invention is to provide a heat dissipation device which is pre-built with an air vent structure, having a good efficiency of heat dissipation in a limited space inside a computer host. Specifically, in the present invention, a cooling fin set is formed by mutually connecting cooling fins into an integral body, with a punching technology. The cooling fins are pre-built with different lengths, such that all kinds of heat dissipation devices of different shapes can be arranged after assembling, so as to shun away from other elements inside the computer host in emplacement. In addition, due to the pre-built assembly, a plurality of diversion baffles can be formed. A certain angle can appear on the diversion baffles, following a direction of wind, to form a proper bus duct, for guiding a direction of air flow when a fan is operating, allowing the air flow to quickly flow toward a heat transmission zone in each gap between the cooling fins, thereby more quickly dissipating heat received by the cooling fins. As the cooling fins of different lengths can be pre-built for the present invention, a combination of different shapes can be formed, and other elements can be shunned away in accordance with a location and an angle of the fan inside the computer host; therefore, all kinds of choices can be available to fit with down-stream vendors and to facilitate the assembly by a user, thereby being extremely suitable for and facilitating the assembly of all kinds of heat dissipation devices. In particular, when the air flow is guided in by the fan, a vortex-shape wind-break wall created by the air flow can be destroyed due to a blocking of the diversion baffles, so as to prevent from a reflux phenomenon resulted by reflection and collision of the air flow. Moreover, a flow field becomes smaller by an included angle formed by the air flow, which increases the wind pressure formed when the air flow blows toward the heat transmission zones, and relatively increases the air flow rate, allowing the air flow which is guided in by the fan to be guided by the diversion baffles to flow quickly and continuously, without causing a stagnant condition. Therefore, it will effectively increase a convection efficiency of the air which passes through the cooling fins, such that a function of the fan can be developed sufficiently, noise of the fan can be reduced, and the best heat dissipation function can be achieved, thereby truly solving an over-heat problem for the computer elements. In addition, as the shapes of cooling fins can be pre-built, the heat dissipation device can be formed integrally with a variation of shapes, thereby allowing the heat dissipation device to be provided with a beautiful appearance.
Accordingly, the primary object of the present invention is to solve a limitation to the heat dissipation device for a conventional computer heat dissipation structure, such that by pre-building the cooling fins of different lengths, the heat dissipation structures of different shapes can be formed to shun away from other computer elements, and all kinds of choices can be available to fit with up-stream and down-stream vendors for manufacturing and assembling.
Another object of the present invention is to solve a limitation to the heat dissipation effect for the conventional computer heat dissipation structure, such that by using the cooling fins of different lengths, the diversion baffles are assembled to form air ducts with a certain angle, which allows the cold air to be quickly guided into the cooling fins following the air ducts, to dissipate the heat and reduce temperature efficiently, thereby achieving the best heat dissipation effect.
Yet another object of the present invention is to provide a design of various combinations by assembling the cooling fins of different lengths, so as to facilitate applying to all kinds of heat dissipation devices.
Still another object of the present invention is to form a variation of shapes integrally, allowing the heat dissipation device to have a beautiful appearance.
