Abstract
The invention discloses a staggered single-end 9-shaped threaded-tube refrigerator evaporator formed by connecting an evaporator tube unit and metal wires. The metal wires are fixedly connected to two sides of coil portions of the evaporator tube unit. The evaporator tube unit is formed by bending a single evaporator tube and comprises the coil portions, inlet and outlet tubes, and a side tube whereby the inlet and outlet tubes are connected with the coil portions; the ends of each two adjacent evaporator tubes, arranged in parallel, of the coil portions are connected in a curvilinear form; one end of each coil portion is in a curvilinear 9-shape; the collinear 9-shaped ends of the adjacent coil portions are staggered. The staggered single-end 9-shaped threaded-tube refrigerator evaporator is further characterized in that the inner wall of the evaporator tube of the evaporator tube unit is provided with an axial spiral groove. The staggered single-end 9-shaped threaded-tube refrigerator evaporator has the advantages that effective length of the evaporator tube is further prolonged, area of contact of refrigerant with the inner wall of the evaporator tube is further enlarged, and heat exchange efficiency is further improved accordingly.
Description
Technical field
The present invention relates to a kind of evaporator of refrigerator, more particularly, the present invention relates to a kind of threaded pipe type evaporator of refrigerator.
Background technology
Threaded pipe type evaporator of refrigerator is formed by connecting by evaporation tube unit and wire, and wire is fixedly connected on evaporation tube cell tray tube portion two sides.Evaporation tube unit is formed by single evaporation tube bending, its main body is coil portions, between the adjacent evaporation tube that coil portions is arranged in parallel, at two ends, with curve shape, connect, curve shape one end, end of the threaded pipe type evaporator of refrigerator coil portions of prior art is 9 fonts, and evaporation tube end 9 font curved arrangement are consistent.Although the threaded pipe type evaporator of refrigerator of this structure can be arranged compactly by evaporation tube, increased the effective length of evaporation tube, but it is still compact not that the 9 font curves that are unanimously arranged in parallel are arranged heat exchanger tube, but heat exchange efficiency is still undesirable, and energy consumption is still higher.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of effective length that can further increase evaporation tube is provided, further improve the single-ended 9 font threaded pipe type evaporator of refrigerator of dislocation type of heat exchange efficiency.
The present invention is achieved through the following technical solutions technical goal.
The single-ended 9 font threaded pipe type evaporator of refrigerator of dislocation type, it is formed by connecting by evaporation tube unit and wire, and described wire is fixedly connected on evaporation tube cell tray tube portion two sides; Described evaporation tube unit is formed by single evaporation tube bending, comprises the limit pipe of coil portions, inlet/outlet pipe, connection inlet/outlet pipe and coil portions; Between the adjacent evaporation tube that described coil portions is arranged in parallel, at two ends, with curve shape, connect; Described coil portions one end curve shape is 9 fonts; Its improvements are: the 9 font curves of described adjacent evaporation tube coil portions one end are staggeredly arranged.
The further technical scheme of the present invention is: the evaporation tube inwall of described evaporation tube unit is provided with axial screw groove.
The present invention further technical scheme is: the shape of cross section of described axial screw groove is trapezoidal.
The present invention compared with prior art, has following good effect:
1. the 9 font curves of adjacent evaporation tube coil portions one end are staggeredly arranged, and make the evaporation tube being arranged in parallel arrange compactlyer, the further like this effective length that increases evaporation tube, thus further improved heat exchange efficiency.
2. evaporation tube inwall is made the tank circuit, has increased the contact area of cold-producing medium and evaporation tube inwall, thereby has increased heat exchange area.Moreover, because the tank circuit can form capillary effect, make the also corresponding increase of wetted area of its inner surface, also improved heat exchange area.The increase of heat exchange area can improve heat exchange property and heat transfer rate.
3. the evaporation tube inwall tank circuit is made the spirality angled with tubular axis line, and the turbulence effect of tube refrigerant fluid is increased, and can fully manage inside and outside heat exchange, thereby reduce the energy consumption of refrigerator, improves the Energy Efficiency Ratio of refrigerator.

The specific embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
The single-ended 9 font threaded pipe type evaporator of refrigerator of dislocation type shown in accompanying drawing, it is formed by connecting by evaporation tube unit 1 and wire 2, and wire 2 is fixedly connected on 1 coil portions 1.3 two sides, evaporation tube unit; Evaporation tube unit 1 is formed by single evaporation tube bending, comprises the limit pipe 1.2 of coil portions 1.3, inlet/outlet pipe 1.1, connection inlet/outlet pipe 1.1 and coil portions 1.3; Between the adjacent evaporation tube that coil portions 1.3 is arranged in parallel, at two ends, with curve shape, connect; Coil portions 1.3 one end curve shapes are 9 fonts, adjacent evaporation tube; 9 font curves of coil portions 1.3 are staggeredly arranged.
In order further to improve heat exchange property and heat transfer rate, the evaporation tube inwall of evaporation tube unit 1 is provided with axial screw groove 3, and in the present embodiment, helicla flute 3 shape of cross sections are trapezoidal.
