Abstract

The utility model relates to a heat dissipation device of a host computer, wherein a condensable second wind tube is arranged on one end of a first wind tube with a metal mesh plate, and the second wind tube can be provided with one or more fans. The first wind tube can be fixed in any expansion slot of the host computer when in use, and the second wind tube is stretched to the expansion slot to make the second wind tube to approach the position where the heat source is generated by a host plate, in order to make the fans which are arranged on the second wind tube to avoid suffering the resistance from an interface card which is inserted in the expansion slot when the fans arranged on the second wind tube inhales hot air in the first wind tube, to achieve the aim of cooling the temperature of the host computer rapidly.

Description

Computer master radiating device

The utility model relates to a kind of computer master radiating device, particularly a kind of improved computer master radiating device.

The utility model is the improvement to No. 94243252.5 utility application (hereinafter to be referred as former patented claim).Former patented claim mainly is: be provided with the plate that can be plugged on expansion slot on one side or on one side at an airduct that is the hollow tube shape, and install one or more fan in the airduct one or both sides, and be provided with the air port at airduct one end, be equiped with a metal otter board on this air port, this metal otter board is provided with the mesh of a plurality of bores below 2mm, during use, just the plate on the airduct is plugged in the expansion slot, metal otter board on the airduct mouth of pipe is locked in the rear window of casing, again the power supply slot of fan and the supply socket of the power supply unit on the main frame are joined, so that the flabellum of fan rotates, the hot-air that produces in the main frame can be sucked in the airduct via fan, discharge by the air port in the airduct again, so that the temperature in the main frame reduces.

Because airduct is one to be fixed on the hollow tube on the expansion slot in the former patented claim, and fan only can be installed on the airduct both sides, so when fan sucked the hot-air on the motherboard in the airduct, the interface card that is fixed on its expansion slot can hinder the hot-air of working as in flowing, and then the suction flow of attenuating fan, in addition, because of airduct only can be fixed in the expansion slot, the method for there is no is stretched to the thermal source place outside expansion slot, so the effect of getting rid of hot-air still can be restricted.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of improved computer master radiating device is provided.

But the utility model is by putting second airduct of condensation at first airduct, one end, on this second airduct fan is housed, so that first airduct can be borrowed the extension of rib second airduct, can produce the thermal source place by more close hair machine plate, and can make that fan is unlikely to be subjected to stopping of interface card on the expansion slot, more can be rapidly and reduce temperature in the main frame effectively

But further improvement of the present utility model is mainly directly and is not equiped with second airduct that metal otter board one end is provided with condensation at first airduct, be equiped with one or more fan on this second airduct, so that when using, first airduct can be installed in arbitrary expansion slot of main frame, simultaneously second airduct is pulled outwardly and extends on the outer motherboard of expansion slot, to produce the thermal source place near motherboard, so that at the fan on second airduct when hot-air is sucked airduct, unlikelyly be subjected to being plugged in stopping of interface card on the expansion slot, and reach the purpose of temperature in the rapid cooling main frame.

Another purpose of the present utility model, be to provide a kind of computer master radiating device, wherein second airduct can be installed one or more fans on side or end face, so that fan can be more near motherboard thermal source place, and suck the hot-air that thermal source produced in the airduct fully, can more effectively dispel the heat in use, be beneficial to practicality.

A purpose more of the present utility model is to provide a kind of computer master radiating device, and wherein second airduct can either direction be installed in the airduct, and makes the fan that is installed on second airduct need not change the position, just can be near the thermal source place of main frame.

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is an embodiment synoptic diagram of the present utility model;

Fig. 3 is another embodiment synoptic diagram of the present utility model;

According to above-mentioned accompanying drawing, describe the utility model in detail below.

As shown in Figure 1, computer master radiating device of the present utility model mainly comprises first airduct 1, the fan 2 and second airduct 4.

Wherein, with reference to Fig. 1, first airduct 1 is provided with the plate 11 that can be plugged in the expansion slot 5 more than at least on one side, then be provided with air port 12 at first airduct, 1 one ends, this air port 12 is provided with metal otter board 13, this metal otter board 13 is provided with the mesh 14 of a plurality of bores below 2mm, on metal otter board 13, then can post a dustproof filter screen (not shown), with the impurity in the filtered air, and first airduct, 1 other end is provided with opening 15, be arranged with second airduct 4 that just can closely be combined in first airduct 1 in this opening 15, these second airduct, 4 one ends are provided with the delivery port 41 relative with opening 15, and the fan hole 42 that is provided with at least more than one on the appropriate location of second airduct 4 to be settling fan 2, and this fan 2 also joins by circuit 21 and a power supply slot 22 and supply socket 23.

Among Fig. 1, its second airduct, 4 both sides respectively are provided with the convex body 44 of protuberance at appropriate location, so that second airduct 4 when being linked in first airduct 1, is installed in the fan 2 on second airduct, 4 sides or the end face, can be by the stopping of convex body 44, and on the unlikely periphery that is pressed against first airduct, 1 opening 15.

As shown in Figure 1 and Figure 2, its second airduct 4 can be installed one or more fan 2 because of needs on its side or top, bottom surface or inside, or will not be provided with and expand outwardly the fan hole 45 (as shown in Figure 2) that formation can be equiped with fan 2 gradually with first airduct, 1 a sheathed end, so that fan 2 can be more near the position at motherboard 61 thermal source places, and the hot-air that thermal source produced is sucked in first airduct 1 fully.

As shown in Figure 3, can be earlier the plate 11 on first airduct, 1 limit one be plugged in the expansion slot 5 at the most close thermal source place, and with the air port 12 of first airduct 1 rear window in the face of casing 62, make the metal otter board 13 on the air port 12 proper in the rear window of casing 62, again second airduct 4 is outwards stretched by first airduct, 1 one ends that are fixed on expansion slot 5, position until the thermal source place, make that the fan 2 that is installed in second airduct 4 is unlikely to be subjected to stopping at the first airduct 1 both sides interface card, again the supply socket 7 of power supply unit on fan 2 power supply slots 22 and the main frame 6 is joined, simultaneously, be plugged on supply socket 23 soft or hard disc on, make the flabellum 24 of fan 2 begin to rotate, so that the hot-air that produces in the main frame 6 can suck in second airduct 4 through fan 2 fully, and discharge via the air port 12 of first airduct 1, to reach the effect of temperature in the rapid cooling main frame 6.

Embodiment of the present utility model only is used to illustrate the utility model enforcement, and those skilled in the art are not difficult that its concrete shape is carried out various equivalences and change, but still belong within essence of the present utility model and the protection domain.
