Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the present invention will be further described.
With reference to Figure 1A and Figure 1B, according to the heat exchanger 1 of such as micro-channel heat exchanger of the present invention comprise header 10 and 12 and the such as flat tube of afflux fluid communication heat exchanger tube 14, be arranged on the fin (not shown) between heat exchanger tube 14, the inlet tube 16 be connected with header and outlet 18.Heat exchanger tube 14 along header 10 axially with arranged at predetermined intervals.Cold-producing medium R, from inlet tube 16, enters header 10, by the heat exchanger tube 14 of such as flat tube, enters header 12, and finally flows out from outlet 18.
As shown in Figures 3 and 4, header 10 has refrigerant inlet 161, and this refrigerant inlet 161 is formed in the tube wall of header 10, such as, in the tube wall of the header relative with heat exchanger tube 14, form refrigerant inlet 161.Header 10 can be formed by pipe, and in this case, the flow direction of the cold-producing medium at refrigerant inlet 161 place can be the radial direction of header 10, and refrigerant inlet 161 can be oppositely arranged with heat exchanger tube 14.Inlet tube 16 is connected to header 10 at refrigerant inlet 161 place and is communicated with refrigerant inlet 161 fluid.Heat exchanger 1 also comprises the downstream being arranged in header 10, on cold-producing medium R flow direction refrigerant inlet 160, or is arranged in header 10, near refrigerant inlet 161 air deflector 20.Air deflector 20 can be relative with refrigerant inlet 161, in plane such as in the plane of the flow direction perpendicular to the cold-producing medium in inlet tube 16 or perpendicular to the flow direction of the cold-producing medium at refrigerant inlet 161 place, the projection of air deflector 20 covers refrigerant inlet 161 completely.
As shown in Figure 3, air deflector 20 can have the plate-like shape of general flat, and such as air deflector 20 is rectangular slab, circular slab, elliptical flat-plate etc.Air deflector 20 is roughly along the axis extension or vertical with the flow of refrigerant direction at refrigerant inlet 161 place of header 10.
As selection, as illustrated in figures 4 and 4, air deflector 20 can have the shape of general conical, such as, formed by V shaped slab or air deflector has V-arrangement shape.In addition, as selection, air deflector 20 can be formed by U-board or air deflector has U-shape, or air deflector 20 is formed by corrugated board or air deflector has corrugated.Air deflector 20 can have: the top 201 relative with refrigerant inlet 161, and the guide part 203 axially extended roughly obliquely from top 201 relative to header 10 on the direction away from refrigerant inlet 161.Described guide part 203 roughly extends obliquely towards the end 101,102 of header 10.Namely air deflector 20 can be general conical, and the pinnacle of air deflector 20 is in the face of refrigerant inlet 161.
