CPU COOLER WITH ONE AIR COLLECTION PART

The present invention relates to a CPU cooler with an air collecting part according to the preamble of claim 1.

The traditional CPU cooling seat is attached to the top of the CPU to cool the heat generated when the CPU is running, with a fan attached to the top of the cooling seat to improve heat exchange and thus reduce the CPU temperature.

The cooling efficiency of the above embodiment still needs to be improved. The fan is used for ventilation, and its motor is provided in the middle, so that a windless zone is formed in the middle below the fan, whereby the cooling fan only serves to ventilate the four corners of the cooling seat and all-round ventilation is not possible. In addition, the ventilating flow is inhibited by the motor installation surface located in the middle, so that a reverse flow of the flow is triggered. Therefore, the cooling effect is significantly reduced. In addition, the heat generated by the CPU is collected in the middle location, so that the conventional embodiment does not enable efficient heat exchange.

The invention is based on the object of eliminating the above-mentioned deficiencies and providing a CPU cooler with an air collecting part, in which the air collecting part and a cooling seat are installed one inside the other, the air collecting part having a curved screen on the inside, which has a cross section tapering downwards, so that the cooling flow introduced by the fan reaches the center of the cooling seat in a collecting and smooth manner, whereby the cooling effect is significantly improved.

Another object of the present invention is to provide a CPU cooler with an air collection part, in which the curved screen has a larger cross section at the top, tapers downward and is curved at the outer edge so as to have a feature for reducing the area of the arc body. The lower part of the curved screen has a small diameter and corresponds to the center of the cooling seat, thereby achieving the avoidance of a windless zone while increasing the flow rate of the introduced air through the cone to increase the cooling effect. In addition, the outer edge of the curved screen is curved to prevent the flow from returning.

These objects are achieved according to the invention by a CPU cooler with an air collection part, which has the features specified in claim 1. Claim 2 relates to an advantageous development of the

Invention. - . ■

■Further features and advantages of the present invention will become apparent upon reading the following description of a preferred embodiment, which refers to the accompanying drawings, in which:

Fig. 1 is a perspective view of the air collection part according to the invention;

Fig. 2 is a bottom view of the air collection part according to the invention;

Fig. 3 is a bottom plan view of the air collection part according to the invention;

Fig. 4 is an overall perspective view of the present invention;

Fig. 5 is an exploded perspective view of the present invention; and

Fig. 6 is a sectional view of the present invention.

Referring to Figs. 1 to 6, the CPU cooler according to the invention comprises an air collecting part 1, a fan 2 and a cooling seat 3, wherein the cooling seat 3 is provided at the top with a round recess 31 which corresponds in shape to the outer edge of the air collecting part 1, so that the air collecting part 1 rests on the same plane as the cooling seat 3, whereby the fan 2 is attached flat to the air collecting part 1.

The air collecting part 1 consists of a one-piece base plate 11 and a cone 12, the base plate 11 being provided with a through hole 111 at each of four corners, which corresponds to the fastening hole 21 of the fan, so that the fan 2 and the air collecting part 1 can be fastened with screws 4 to screw holes 32 of the cooling seat.

The cone 12 tapers downwards and is curved on the outside, with the interior of the cone 12 being provided in the middle with a curved screen 13, which has an integrally formed, cross-shaped

connecting rib 14 through which four ventilation channels 15 are formed, increasing the support strength of the installation of the curved screen 13 inside the cone 12.

The curved screen 13 has a larger cross-section at the top, tapers downwards and is curved at the outer edge, so that it has a feature for reducing the area of the arc body. The lower part of the curved screen 13 has a small diameter and corresponds to the center of the cooling seat 3, thereby avoiding a windless zone,

while the flow rate of the introduced air through the cone 12 increases to increase the cooling effect. In addition, the outer edge of the curved screen 13 is curved to prevent the flow from returning.

From the above description, it is clear that the air collecting part 1 on which the fan 2 is provided and the cooling seat 3 are installed one inside the other. The ventilation ducts 15 inside the air collecting part 1 correspond to the middle position of the cooling seat 3. The heat generated by the CPU is directly collected by the air collecting part 1, whereby a greatly improved, efficient heat exchange is carried out between the heat and the cooling air blown out by the fan 2 (see Fig. 6). In addition, the outer edge of the curved screen 13 is curved to prevent the flow from flowing backwards.

The invention is not limited to the embodiment described, but rather a wide range of possible variations and modifications will become apparent to those skilled in the art within the scope of the invention.
