Technical Field

The utility model belongs to the technical field of refrigerators, and particularly relates to an ultrathin efficient finned evaporator and a refrigerator.

Background

In the prior art, the evaporator of the air-cooled refrigerator and a matched air duct system account for the gross volume of the refrigerator in a high proportion, and are limited by the process levels of evaporator expansion, bending, forming and the like and the matching of a refrigerating system and other factors under the current process conditions, most of evaporators for the refrigerator at present are formed by adopting aluminum pipe expansion pipes with the outer diameter of 8mm and the wall thickness of 1mm, so that the integral evaporator is made of more materials and higher in cost, the inner volume of a pipeline is large, the thickness of the evaporator is large, and meanwhile, the refrigerant filling amount of the system is more, which is contrary to the current environment-friendly direction.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide the ultrathin efficient finned evaporator which can reduce the material consumption of an evaporation pipeline under the condition of the same height, has long pipeline and small pipe diameter and reduces the refrigerant charge.

The utility model also provides a refrigerator using the ultrathin efficient fin evaporator.

The utility model provides an ultrathin efficient finned evaporator, which comprises at least one layer of evaporation plate arranged in the horizontal direction, wherein the evaporation plate comprises a stacked and bent evaporation pipeline, radiating fins are uniformly distributed and inserted in linear parts of the evaporation pipeline, end plates are arranged at bent parts on two sides of the evaporation pipeline, and a refrigerant inflow port and a refrigerant outflow port are formed in the evaporation pipeline extending out of the end plate on one side; the outer diameter of the evaporation pipeline is 6.35mm, the wall thickness is 0.75mm, and the radius of the R corner of the bent pipe at the bending part is 10 mm.

FIG. 2 is a schematic view of an evaporator with three evaporation plates according to the present invention.

Detailed Description

Referring to fig. 1, the ultrathin high-efficiency finned evaporator provided by the utility model comprises at least one layer of evaporation plate 1 arranged along the horizontal direction, wherein the evaporation plate 1 comprises stacked and bent evaporation pipelines 11, radiating fins 12 are uniformly distributed and inserted in straight line parts of the evaporation pipelines 11, end plates 13 are arranged on bent parts at two sides, a refrigerant inflow port 14 and a refrigerant outflow port 15 are arranged on the evaporation pipeline 11 extending out of the end plate 13 at one side, and in order to solve the technical problems in the background art, the technical scheme of the utility model is that the outer diameter of the evaporation pipeline 11 is 6.35mm, the wall thickness is 0.75mm, and the radius of an angle R of a bent pipe at the bent part 16 is 10 mm.

Because the evaporation pipeline 11 is a thin-wall pipeline with small diameter, the number of pipes used for manufacturing is small, the weight is light, and the manufacturing cost has obvious advantages compared with the existing products in the market; adopt return bend R angle radius to be 10mm, under the prerequisite of the same row number pipeline, whole thickness is little 15mm at least than current product, and the whole percentage of volume of refrigerator improves greatly, and the return bend radius is 10 mm's R angle moreover, and under the prerequisite of same height, the evaporator pipeline is longer, and the refrigerant is more abundant in the pipeline evaporimeter, and refrigeration efficiency is high. The pipe diameter of the evaporation pipeline 11 is small, the refrigerant charging amount of the refrigerator refrigerating system is reduced, the mass flow rate of the refrigerant is increased, and the evaporation temperature is reduced due to the improvement of the heat transfer coefficient of the air side. And the filling amount is small, so that the influence of the refrigerant on the environment is directly reduced, and the method is more in line with the relevant national policies of environmental protection.

In this embodiment, the evaporation pipe 11 is made of an aluminum pipe. The aluminum material has stronger ductility, the manufacturing pipeline is easy to process, the bad phenomenon of pipe leakage is not easy to occur, the aluminum pipe has ultrahigh corrosion resistance, and the aluminum pipe is not easy to be corroded by refrigerant and food residues in daily use, so that the service life of the refrigerator is ensured.

In the present embodiment, referring to fig. 1, the number of the evaporation plates 1 is two, and the overall thickness is 45 mm.

In the present embodiment, referring to fig. 2, the number of the evaporation plates 1 is three, and the overall thickness is 60 mm.

The utility model also provides a refrigerator which comprises a refrigerator body provided with the ultrathin efficient fin evaporator.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
