Abstract
The utility model relates to an evaporator and a refrigerator with the evaporator, providing an inner fin type evaporator and an refrigerator with the evaporator, a inner fin is arranged in the evaporator, a turbulence structure for reinforcing refrigerant heat exchange is adopted to enhance convection heat exchange strength in pipeline, so as to improve heat transfer coefficient of evaporator. The refrigerator comprises an evaporator, an empty tubular structure is arranged in the evaporator, the inner fins are arranged evenly on the inner circumference of the empty tube, the refrigerator adopts internal thread fin type evaporator, whether even fins or high-low fins, the heat exchange area of refrigerant in pipeline is added at different extent, so as to facilitate to destroy laminar state at pipe wall, enhance turbulence degree of liquid refrigerant, thereby increasing convection heat exchange coefficient of refrigerant inside the pipeline greatly.
Description
Technical field
The utility model technology relates to a kind of evaporimeter and has the refrigerator of this evaporimeter.
Background technology
Refrigerator of the prior art, evaporimeter generally all are set to hollow tubular structures, and hollow pipe inside is smooth surface.By capillary-compensated, the cold-producing medium of gas-liquid mixed state enters into heat convection in the evaporimeter like this, and behind the absorption heat, the overwhelming majority becomes gaseous refrigerant, gets back to compressor by muffler.The evaporimeter of this structure, cold-producing medium is lower at the evaporation velocity in pipes, with the flow regime at smooth surface place in the pipe be laminar flow.Therefore convection transfer rate is lower in the pipe, causes the heat transfer coefficient of evaporimeter lower, so refrigeration neither be fine.
Summary of the invention
Technical purpose of the present utility model is to overcome above defective, provide in a kind of evaporator tube inner fin has been set, take to strengthen the turbulence structure of cold-producing medium heat exchange, convection heat transfer intensity in the reinforced pipe, thus improve the evaporimeter of evaporimeter heat transfer coefficient and have the refrigerator of this evaporimeter.
The technical scheme of inner fin formula evaporimeter of the present utility model is such: it is set to hollow tubular structures, and inner fin evenly is set on the inner periphery of hollow pipe.
The height unanimity of inner fin, the height of inner fin are arranged on 0.1～0.5 millimeter, and the wall thickness of hollow pipe is set to 0.1～0.5 millimeter.
Inner fin also can be set to the height fin apart from one another by structure, the height of inner fin is arranged on 0.1～1.5 millimeter, the wall thickness of hollow pipe is set to 0.1～1.5 millimeter.
Inner fin on the hollow pipe inner periphery is set to 5～80.
Inner fin can be set to waveform, also can be set to trapezoidal.
The technical scheme that has the refrigerator of above-mentioned evaporimeter of the present utility model is such: it comprises evaporimeter, and evaporimeter is set to hollow tubular structures, and inner fin evenly is set on the inner periphery of hollow pipe.
The height unanimity of inner fin, the height of inner fin are arranged on 0.1～0.5 millimeter, and the wall thickness of hollow pipe is set to 0.1～0.5 millimeter.
Inner fin also can be set to the height fin apart from one another by structure, the height of inner fin is arranged on 0.1～1.5 millimeter, the wall thickness of hollow pipe is set to 0.1～1.5 millimeter.
Inner fin on the hollow pipe inner periphery is set to 5～80.
Inner fin can be set to waveform, also can be set to trapezoidal.
Adopt internal thread wing shape evaporimeter, be even wing or the height wing all in various degree increase the heat exchange area of tube refrigerant, help destroying the laminar condition at tube wall place, strengthened the turbulence level of liquid refrigerant, increased cold-producing medium greatly at the inboard convection transfer rate of pipe.
