When the heat dissipation device with the above-mentioned structure is in use, when the airflow of the fan passes under the guide fins and is about to flow out, it will be guided by the side wall and blow downward, thereby blowing to the circuit board ( or the heating element on the motherboard), so that the cooling device can also make the heating element near the CPU blown by the airflow to dissipate heat except that the CPU (central processing unit) of the computer can be cooled. In addition, as can be seen from Figure 3 of this case, there is also a bottom edge (bottom edge) on the bottom side of the guide fins, which is used to block part of the airflow at the bottom of the guide fins to make it turbulent And blow down, thereby can blow to the heating element below this bottom edge.

However, in the above-mentioned existing structure, the guide fins must be assembled together with the first fins, which also limits the assembly method of the guide fins, and the guide fins cannot be independently installed with other heat sinks. .

Detailed ways

In order to describe the structure and characteristics of the present utility model in detail, the following preferred embodiments are given and illustrated as follows in conjunction with the drawings, wherein:

As shown in Figure 1, an airflow guide plate 10 used in a radiator provided by a preferred embodiment of the present invention mainly has:

A plate body 11 has a transversely extending crosspiece 12, and a rear inclined guide portion 14 obliquely extending backward and downward from the top edge of the crosspiece 12, and the rear inclined guide portion 14 is directed toward the first The side (the left side in this embodiment) extends for a predetermined length, and the board body 11 has a front oblique guide portion 16 obliquely extending forward from the crosspiece portion 12 to the first side for a predetermined length. The projected position of the end of the front slanted guide portion 16 onto the rear slanted guide portion 14 is roughly located in the middle section of the rear slanted guide portion 14 .

The board body 11 has three fixing parts 18 respectively located on the crosspiece part 12, the rear inclined guide part 14, and the front inclined guide part 16, and the fixing parts 18 are used to cooperate with a radiator 21 (shown in FIG. on Figure 2 to Figure 4). In this embodiment, each of the fixing parts 18 is a lug 181 , and a through hole 182 is formed on the lug 181 , and the through hole 182 can be locked by a screw 183 (shown in FIG. 3 ).

It can be seen from the above structure that when the airflow is blown from the front of the airflow guide plate 10 of the present utility model, the airflow will be separated by the front inclined guide part 16 first, and part of the airflow will be guided by the front inclined guide part 16. Lead and flow out to the side, in terms of the direction in Figure 1, it flows out to the right. Another part of the airflow flows backward without being guided by the front slanted guide portion 16 , and then is guided by the rear slanted guide portion 14 to flow obliquely downward.

2 to 3 show the state that the airflow guide plate 10 of the present invention is fitted on a radiator 21 . Wherein, the heat sink 21 is composed of several heat dissipation fins 22, a heat dissipation plate 24 located below the heat dissipation fins 22, and several heat dissipation pipes 26 passing through the heat dissipation fins 22 and connected to the heat dissipation plate 24 , and a fan 28 arranged on the sides of the cooling fins 22 and the cooling plate 24 . The airflow guide plate 10 of the present utility model is locked on the heat dissipation plate 24 with a screw 183 respectively by the fixing parts 18, and the airflow guide plate 10 is located at the opposite side of the heat dissipation plate 24 relative to the fan 28. side.

When the heat sink 21 with the above structure is in operation, the airflow generated by the fan 28 flows between the heat dissipation fins 22 to take away the heat energy on the heat dissipation fins 22 to achieve the effect of heat dissipation. In addition, as shown in FIG. 4 , the airflow (indicated by arrows) generated by the fan 28 also partially flows through the bottoms of the cooling fins 22 (shown in FIG. 3 ) and is received by the airflow guide plate 10. , which in turn creates airflow to the sides and airflow to the rear and downward. As shown in Figure 5, when it is installed on a circuit board 31, the airflow flowing to the side can provide heat dissipation for the heating element 32 located on the circuit board 31 on the side of the radiator 21, and the airflow flowing to the rear and downward can be The heating element 32 located on the circuit board 31 behind the radiator 21 can dissipate heat.

As can be seen from the above, the effect that the utility model can achieve is:

1. Compatible with a variety of radiators, and has a wide range of applications: the airflow guide plate of the utility model can make the original radiator with no airflow guiding function under the heat dissipation fins have the effect of airflow guidance. Since the utility model is independently installed on the heat dissipation plate of the radiator, it can be applied to various radiators with airflow passages below. Therefore, the utility model really improves the problem that the single type of the prior art cannot cooperate with other kinds of radiators.

2. Additional heat dissipation effect: With the utility model, the airflow can be guided to flow to one side and backward and downward, thereby achieving the effect of additionally blowing to other heating elements on the circuit board to dissipate heat. And the mode of lateral guidance of the utility model is also different from the mode of the aforementioned cases, the side of the utility model is open, while the side of the prior art is closed to make the airflow go down, the airflow can The covered area is small, so the side heat dissipation effect of this case is better than that of the prior art.
