An embodiment of the present invention provides a cooling device, referring to fig. 1 and in combination with fig. 2 and 3, the cooling device includes: plug 100, first fan set 200, second fan set 300, first windshield 400, and second windshield 500.
The first wind deflector 400 and the second wind deflector 500 are open wind deflectors formed by two side plates 501 and a middle support plate 502.
It should be noted that the two side plates 501 and the one middle support plate 502 may be connected by welding or may be fixedly connected by screws, and in this application, the two side plates 501 and the middle support plate 502 are not limited to welding and screw connection, and other connection methods may also exist. In a specific application, the connection between the two side plates 501 and the middle support plate 502 needs to be selected according to requirements.
The open type wind deflector is a U-shaped wind deflector.
Preferably, the distance between the two side plates 501 at the opening of the first wind deflector 400 and the second wind deflector 500 is less than the length of the middle support plate 502.
It should be noted that the distance between the two side plates 501 at the opening of the first wind deflector 400 and the second wind deflector 500 may be smaller than the length of the middle support plate 502, and the distance between the two side plates 501 at the opening of the first wind deflector 400 and the second wind deflector 500 may also be equal to the length of the middle support plate 502.
For easy understanding, the distance between the two side plates 501 at the opening of the first wind deflector 400 and the second wind deflector 500 is smaller than the length of the middle support plate 502. The following examples are given.
As shown in fig. 4, in the figure, the distance between two side plates 501 at the opening is a, a is 15cm, the length of the middle support plate 502 is b, and b is 18cm, that is, the distance a between the two side plates 501 at the opening of the first wind deflector 400 and the second wind deflector 500 may be smaller than the length b of the middle support plate 502.
It should be further noted that, when the first fan set 200 blows in cold air into the test fixture, because the distance between the first wind shield 400 and the two side plates 501 at the opening of the second wind shield 500 is smaller than the length of the middle support plate 502, the two side plates 501 can gather the air blown in by the first fan set 200 and blow in the test fixture, so that the temperature reduction of the test fixture is more obvious.
Preferably, the first wind deflector 400 and the second wind deflector 500 are plastic wind deflectors.

It should be further noted that, since the heat dissipation plate of the test fixture is of a gold finger structure, the two side plates 501 of the second air baffle 500 need to be aligned to the plurality of heat dissipation plates and the gaps of the test fixture, and the heat dissipated by the plurality of heat dissipation plates and the gaps of the test fixture is exhausted through the second fan set 300.
It should be noted that, because the second fan set 300 needs to discharge the hot air in the test fixture, the second fan set 300 needs to be fixed at the other end of the test fixture, and the air outlet of the second fan set 300 is aligned to the opposite direction of the test fixture, that is, the second fan set 300 is arranged at the opposite end of the first fan set 200, and the air outlet directions are the same, therefore, the second fan set 300 needs to be fixed on the motherboard by the first clips 302 arranged on the M fan bases, and the clip mouths of the first clips 302 face the air outlet directions of the M fans in the same direction, so that the M fans 301 can be fixed on the motherboard, and the M fans 301 discharge the hot air in the test fixture.
