Specifically, the heat dissipation device includes a flow guide structure 2, the flow guide structure 2 is disposed in the air inlet casing 1, and the air flow channel is formed between the flow guide structure 2 and the inner wall of the air inlet casing 1. The flow guide structure 2 can guide the airflow of the air inlet 13, and the purpose that the flow area of the airflow channel is gradually reduced is achieved by utilizing the inclination of the flow guide structure 2.
Preferably, the flow guide structure 2 is a flow guide plate, the side of the flow guide plate facing the air outlet 14 is a windward side, and the airflow flows under the flow guide effect of the windward side.
The air inlet casing 1 is provided with a first side plate 11 and a second side plate 12 which are adjacent to each other, an air inlet 13 is formed in the first side plate 11, a plurality of air outlets 14 are formed in the second side plate 12, and the airflow channel is formed between the flow guide structure 2 and the second side plate 12. The air current is by the air intake 13 inlet port on the first curb plate 11, and its flow direction is to flowing inside the air inlet casing 1, and water conservancy diversion structure 2 leads the air current so that the air current is close to the direction of second curb plate 12 gradually to realize reducing gradually flow area's purpose. Preferably, the second curb plate is located the top of first curb plate 11, and the air current can climb when flowing on water conservancy diversion structure 2 to further reduce the air current velocity of flow and increase gas pressure, guarantee the air-out effect of air outlet.
Preferably, air inlet casing 1 is the cuboid structure, and the cuboid structure has first terminal surface and the second terminal surface along length direction, and the cuboid structure still has the first side that is located between first terminal surface and the second terminal surface, and first terminal surface constitutes first curb plate 11, and first side constitutes second curb plate 12, and all air outlets 14 all are located first side to the interval is arranged in the direction along first terminal surface to second terminal surface. At this time, the airflow enters the air inlet housing 1 from the air inlet 13 and flows under the action of the flow guide structure 2, when the airflow passes through the air outlet 14, a part of the airflow flows out from the air outlet 14, and the rest of the airflow continues to flow along the flow guide structure 2 until the air outlet 14 farthest from the air inlet 13 is reached, and all of the airflow is discharged.
Optionally, an included angle is formed between the plane of the flow guide structure 2 and the plane of the second side plate 12, and the included angle ranges from 3 ° to 5 °. When the angle of contained angle is too big, the thickness grow of air inlet casing 1 causes the heat abstractor and the applied volume increase of predetermineeing the structure of heat abstractor to the angle of climbing of air current is too big, is unfavorable for the air current to flow. When the angle of the included angle is too small, the climbing angle of the air flow is too small, the air outlet uniformity of the air outlet 14 cannot be guaranteed, meanwhile, the speed reduction of the air flow is not obvious, the pressure intensity is not obviously increased, and the air outlet effect is poor.

In order to further improve the air outlet effect of each air outlet 14, a wind shield 3 is arranged between every two adjacent air outlets 14, the wind shield 3 is arranged inside the air flow channel, and an air passing space 31 is formed between the wind shield 3 and the flow guide structure 2.
