Embodiment 1
[0055] The diversion structure can be: as image 3 As shown, the third side 33 of the air duct 39 relative to the air outlet 320 and the fourth side 34 relative to the air inlet 310 are transitionally connected by an arc surface 35, wherein the arc surface 35 The section line can be 1 / 4 arc, and the radius of the formed arc section line can be 5mm~60mm;
[0056] or as Figure 4 As shown, the third side 33 relative to the air outlet 320 in the air duct 39 and the fourth side 34 relative to the air inlet 310 are transitionally connected by a plane 36, wherein the plane 36 is connected to the second side respectively. The included angle formed by the three sides 33 and the fourth side 34 may be 45°, and the length of the section line of the plane 36' may be 5 mm to 60 mm;
[0057] or as Figure 5 As shown, the third side 33 relative to the air outlet 320 in the air duct 39 and the fourth side 34 relative to the air inlet 310 are transitionally connected to the plane 36 through...
Embodiment 2
[0059] Such as Figure 6 As shown, the air guide structure may be: the second side 32 is provided with a recessed portion that is recessed toward the inside of the air duct 39, the cross section of the recessed portion is formed by an arc surface 37 and a plane 38, and the The arc surface 37 is tangent to the side of the air outlet 320, and the plane 38 is inclined to the second side 32, so that when the airflow flows to the air outlet 320, the concave part can change the flow direction of the airflow, which can The interference of the airflow at the air outlet 320 is reduced, thereby improving the air outlet efficiency.
[0060] Wherein, the section line shape of the arc surface 38 can be 1 / 8~7 / 8 arc, and the arc section line radius of the arc surface 38 can be 5mm~30mm; the opening width of the concave part is at least It must be greater than 10mm.
Embodiment 3
[0062] refer to Figure 7 or Figure 8 , the guide structure can also be: N (N greater than or equal to 1) guide plates are arranged on the side of the air duct 39 located at the air outlet 320, and the N guide plates will The air outlet 320 is divided into N+1 air outlet units, and the division ratio can be equal or unequal. When the air flow is close to the air outlet 320, the air flow can flow out from the air outlet in a relatively orderly manner under the action of multiple air outlet units, so as to minimize the phenomenon that the heat exchange effect is not good due to the turbulence of the air flow when it flows out Appear.
[0063] Because the deflectors are arranged step by step in the air duct 39, the length of the deflectors (the length direction here refers to the direction in which the air flows from the air inlet to the air outlet) increases successively, so that the air flow in the lowest layer of the air duct The flow path in the unit is relatively short, ...
