Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention. Fig. 2 is a schematic view of the flowing direction of gas in the present invention. As shown in figure 1 and figure 2, the whole body of the utility model is made of stainless steel. The utility model provides a wind channel is the horizontal direction. The air duct is composed of a shell 11 and an air duct sealing plate 9.
The vertical surface of the head end of the air duct is an air inlet plate 10, and a plurality of air inlet holes are arranged on the air inlet plate 10. An air outlet plate 1 for air outlet is arranged on the bottom surface of the tail end of the air duct, and a plurality of strip-shaped air outlet holes are formed in the air outlet plate 1. Fig. 3 is a schematic view of an embodiment of the housing of the present invention. Fig. 4 is a schematic view of the housing showing the orientation of the outlet panel. Referring to fig. 3 and 4, the position of the outlet plate 1 on the housing 11 can be further understood.
In the air duct, a capacitor 8, a radiator 7, a fan 4, and a waterproof board 3 are mounted in this order from the head end to the tail end.
When the air-cooling device works, air enters the air channel from the air inlet plate 10, passes through the capacitor 8 and the radiator 7, and is discharged from the air outlet plate 1 on the bottom surface of the air channel, so that effective heat dissipation is provided for the capacitor 8 and the radiator 7.
The capacitor 8 is fixed on the top surface of the air duct and is positioned between the air inlet plate 10 and the radiator 7. Preferably, a radiator support plate 6 is fixed to the bottom surface of the air duct. The radiator support plate 6 is located below the radiator 7. The radiator supporting plate 6 comprises a flow guide inclined plane, a flow guide horizontal plane and a flow guide rear side surface which are connected into a whole, and an obtuse angle is formed between the flow guide inclined plane and the gas source direction. The flow guiding level may be used to support the heat sink 7.
The radiator support plate 6 can support the radiator 7 and plays a key role in guiding the flow. The radiator supporting plate 6 can guide gas to enable the gas to flow through the middle of the fins of the radiator 7, the flowing direction of the gas is improved, and the temperature rise of 3-5 ℃ can be effectively reduced.
The fan 4 is fixed on the fan mounting bracket 5. The fan mount 5 is obliquely fixed between the top and bottom surfaces of the duct. The fan mount 5 forms an obtuse angle with the direction of the gas source. The fan 4 draws out air in the air duct. Due to the orientation of the fan mounting 5, the air drawn by the fan 4 is diverted from a horizontal flow to an inclined downward flow, directly onto the upper surface of the flashing 3.
A waterproof board 3 inclined relative to the air-out board 1 is arranged above the air-out board 1. A guide plate 2 is arranged at the tail end of the air duct. The included angle between the air outlet plate 1 and the waterproof plate 3 is an acute angle in the direction towards the guide plate 2. With reference to fig. 2, the waterproof board 3 and the air deflector 2 thus arranged can guide the air drawn by the fan 4 to the direction of the air-out board 1 below the waterproof board 3. Furthermore, both sides of the waterproof board 3 are provided with side boards connected with the bottom surface of the air duct. The two side plates and the waterproof plate 3 together form a waterproof cover for covering the air outlet plate 1, and the air can be further concentrated and discharged from the air outlet plate 1. Meanwhile, the waterproof board 3 is arranged behind the long holes of the air outlet board 1, 99% of rainwater can be prevented from entering the machine, the waterproof effect is very obvious, and meanwhile, a certain backflow effect can be achieved.
Preferably, the baffle 2 comprises a first baffle surface and a second baffle surface connected to each other. The first flow guide surface is fixed between the bottom surface of the air duct and the vertical surface at the tail end of the air duct, and the second flow guide surface is fixed between the vertical surface at the tail end of the air duct and the top surface of the air duct. If the direction of the gas flowing in the wind tunnel is taken as a standard, the angle between the first flow guide surface and the gas source direction is preferably larger than the angle between the second flow guide surface and the gas source direction. The guide plate 2 of such a special structure cooperates with the waterproof plate 3, as shown in fig. 2, so that the gas pumped out by the fan 4 firstly rises to the second guide surface along the waterproof plate 3, then is guided by the second guide surface and the first guide surface at a certain angle together, enters between the waterproof plate 3 and the air outlet plate 1, and finally is discharged downwards by the air outlet plate 1 after being guided by the bottom surface of the waterproof plate 3.
Referring to fig. 2, the guide plate 2 at the end of the air duct can directly change the flow direction of the air and reduce the wind resistance, so that the air drawn from the fan 4 can be more smoothly discharged from the air outlet plate 1. Without the baffle 2, a large amount of air can be accumulated at the end of the air duct, which affects heat dissipation.
To sum up, the utility model discloses a position design of unique air outlet to and guide plate 2 and waterproof board 3's design, make the complete machine possess better heat dissipation and waterproof performance.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
