Abstract
The invention discloses a tube-on-sheet evaporator. An S-shaped heat exchange tube is fixed on a heat exchange sheet, and the heat exchange sheet is provided with turnup portions used for fixing the heat exchange tube. A groove corresponding to the heat exchange tube is formed in the heat exchange sheet, and the heat exchange tube is fixed in the groove in the surface of the heat exchange sheet in a clinging manner. Curves at two ends of the heat exchange tube are 9-shaped, and the 9-shaped curves at the two ends face to the same side. The adjacent 9-shaped curves at the two ends of the heat exchange tube are staggered. Further improvement includes that the heat exchange tube is adhered in the groove of the heat exchange sheet. Effective length of an evaporating tube is increased significantly; furthermore, by full contact of the heat exchange sheet and the heat exchange tube, heat dissipation area is increased, heat exchange efficiency is improved remarkably, and service life of the evaporator is prolonged.
Description
Technical field
The present invention relates to the plate-tube type evaporator of refrigerator.
Background technology
Existing plate-tube type evaporator comprises the coiled heat exchanger tube on heat exchanger plates and heat exchanger plates face, heat exchanger tube is fixed on heat exchanger plates and is formed with one side adhesive tape.Layout fixingly because adhesive tape adopts, heat exchanger tube is round tube, and heat exchanger plates warpage is large, and planarization is poor, and can not be close between heat exchanger tube and inner container of icebox, makes its contact area little, and heat exchange area is little, and therefore the heat exchange effect of heat exchanger plates is insufficient.In " plate-tube type evaporator " patent of China Patent No. ZL201220469565.0, the groove corresponding with heat exchanger tube is set on heat exchanger plates, heat exchanger tube is close in the groove that is fixed on heat exchanger plates surface, like this, increase heat exchange area, improve heat exchange efficiency, but the plate-tube type evaporator heat exchange of this structure insufficient, heat exchange efficiency is unsatisfactory.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide one can carry out abundant heat exchange, significantly improve the plate-tube type evaporator of heat exchange efficiency.
The present invention is achieved through the following technical solutions technical goal.
Plate-tube type evaporator, comprises heat exchanger plates, heat exchanger tube, and described heat exchanger tube is snakelike and is fixed on heat exchanger plates, and heat exchanger plates is provided with the turnup portion of fixing heat exchanger tube; Described heat exchanger plates is provided with the groove corresponding with heat exchanger tube, and heat exchanger tube is close in the groove that is fixed on described heat exchanger plates surface; Its improvements are: described heat exchanger tube two ends curve shape is 9 fonts, and the 9 font curves at two ends are towards the same side; The adjacent 9 font curve dislocation at described heat exchanger tube two ends are arranged.
Further improve as the present invention, described heat exchanger tube is bonded in the groove of heat exchanger plates.
The present invention compared with prior art, has following good effect:
1. heat exchanger tube two ends curve shape is all 9 fonts, and the adjacent 9 font curve dislocation layouts at two ends, like this, the adjacent 9 font curves at two ends are avoided mutually, can make heat exchanger tube arrange compactly, significantly increase the effective length of evaporation tube, thereby improve heat exchange efficiency.
2. heat exchanger tube is close in the groove that is bonded in heat exchanger plates surface, can make like this heat exchanger plates fully contact with heat exchanger tube, and increasing heat radiation area, significantly improves heat exchange efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A cutaway view in Fig. 1.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
Plate-tube type evaporator shown in accompanying drawing, comprises heat exchanger plates 1, heat exchanger tube 2, and heat exchanger tube 2 is snakelike and is fixed on heat exchanger plates 1, and heat exchanger plates 1 is provided with the turnup portion 3 of fixing heat exchanger tube 2; Heat exchanger plates 1 is provided with the groove corresponding with heat exchanger tube 2; Heat exchanger tube 2 two ends curve shapes are 9 fonts, and the 9 font curves at two ends are towards the same side; The adjacent 9 font curve dislocation at heat exchanger tube 2 two ends are arranged.
In order further to increase area of dissipation, heat exchanger tube 2 is close in the groove that is bonded in heat exchanger plates 1 surface.
