Technical field
The present invention relates to freezing and refrigeration refrigeration technology fields, and in particular to a kind of air-cooler of fin flat tube integral structure.
Background technique
Air-cooler cooling rate is fast, cold interior air-flow even tissue, therefore is widely used in fridge-freezer, usually Freon refrigeration system be nest plate pipe heat exchanger, piece and pipe are separate structures, reduce thermal contact resistance using tube expansion, but still difficult To avoid the presence of thermal contact resistance, heat transfer coefficient is caused to reduce, the performance decline of refrigeration system, while being easy frosting, defrosting water Cleaning is not thorough.
Summary of the invention
The present invention be in order to overcome the shortcomings in the prior art place, a kind of cold wind of fin flat tube integral structure is provided Machine, it is energy saving to improve the performance of the refrigeration system of fridge-freezer, protect environment.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of air-cooler of fin flat tube integral structure, is changed including frame and at least one set being set in the frame Thermal modules, the heat exchange module include that the pipe inner section of multiple parallel arrangements is the flat tube of rectangular configuration and is formed in described The rectangular area size of flat tubular fin on flat tube, the pipe inner section of multiple flat tubes is sequentially reduced from a side to the other side, phase It is connected between adjacent flat tube by reducing elbow, forms the structure by S-shaped shape trend;The flat tube and flat tubular fin are single entirety Cold-formed integral structure;The other end positioned at a flat tube of side is connect with gas collecting tube, positioned at one of the other side The other end of flat tube is connect with liquid supply pipe.
The frame is welded to form rectangular-shaped framework by four end plates, and the both ends of the flat tube are each passed through the correspondence of frame The end plate of side, the reducing elbow, gas collecting tube and liquid supply pipe are located at the outside of the frame.
One end of the liquid supply pipe and gas collecting tube blocks, the other end opens wide, and divides on the side wall of the liquid supply pipe and gas collecting tube Aperture corresponding with the flat tube connected is not opened up.
The entrance of the liquid supply pipe and the reducing pressure by regulating flow component outlet of refrigeration system connect, the outlet and system of the gas collecting tube The entrance of cold compressor connects.
The flat tubular fin is rectangular-shaped.
The air-cooler of fin flat tube integral structure of the present invention draws processing fin flat tube integral structure using cold extrusion, disappears Except the thermal contact resistance of fin and round tube, enhance heat-transfer effect, the cleaning of defrosting water thoroughly, reduces heat transfer temperature difference, improves refrigeration system Thermal performance, structure is simple, energy saving, protects environment.
Detailed description of the invention
Fig. 1 is the schematic diagram of the air-cooler of fin flat tube integral structure of the invention;
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
Below in conjunction with the drawings and specific embodiments to the detailed description of the invention.
As shown in Figure 1 to Figure 2, the air-cooler of fin flat tube integral structure, including:
Frame 1, the first flat tube 2, the first flat tubular fin 3, third bend pipe 4, the first bend pipe 5, the second flat tube 6, the second flat tube Fin 7, third flat tube 8, third flat tubular fin 9, the 4th flat tube 10, the first flat tubular fin 11, liquid supply pipe 12, the second bend pipe 13, Gas collecting tube 14.
First flat tube 2 and the first flat tubular fin 3 outside pipe, the second flat tube 6 and the second flat tubular fin 7 outside pipe, the Three flat tubes 8 and the third flat tubular fin 9 outside pipe, the 4th flat tube 10, which is that single entirety is cold with the first flat tubular fin 11 outside pipe, to be added The molding integral structure of work, the first flat tube 2, the second flat tube 6, third flat tube 8, the 4th flat tube 10 pipe inner section be rectangle knot Structure, and rectangular area size is sequentially reduced, and the third bend pipe 4, the first bend pipe 5, the second bend pipe 13 are variable-diameter structure.
The flat tubular fin is rectangular-shaped, and area is all the same, and the outer rim of adjacent flat tubular fin contacts with each other, Duo Gebian The outer rim of pipe fin contacts with each other and splices a plane of rectangular in form.
The frame 1 is welded to form by end plate up and down, the right end difference of the right end of the first flat tube 2 and the second flat tube 6 It is welded to connect across the correspondence aperture of 1 right end plate of frame and the both ends of third bend pipe 4, the left end of the second flat tube 6 and third flat tube 8 left end is each passed through the correspondence aperture of 1 left side plate of frame, the both ends welded connecting with the second bend pipe 13, the right side of third flat tube 8 The both ends welded connecting in corresponding aperture and the first bend pipe 5 that 1 right end plate of frame is each passed through with the right end of the 4th flat tube 10 is held, The left end of first flat tube 2 passes through the correspondence aperture of 1 left side plate of frame, is welded to connect with the corresponding aperture of gas collecting tube 14, and the 4th is flat The left end of pipe 10 passes through the correspondence aperture of 1 left side plate of frame, is welded to connect with the corresponding aperture of liquid supply pipe 12.
One end of the liquid supply pipe 12 and gas collecting tube 14 blocks, the other end opens wide, side wall open up respectively with connect it is flat Manage corresponding aperture;The entrance of the liquid supply pipe 12 and the reducing pressure by regulating flow component outlet of refrigeration system connect, gas collecting tube 14 Outlet is connect with the entrance of refrigeration compressor.
