Finned evaporator

Abstract

The invention relates to a finned evaporator. The finned evaporator comprises a coil pipe, a plurality of fins, a left side plate, a right side plate, a first connecting pipe and a second connecting pipe, wherein the coil pipe is sleeved with the fins, the left side plate and the right side plate are arranged at the two ends of the coil pipe, and the first connecting pipe and the second connecting pipe are connected with the two ends of the coil pipe respectively. The coil pipe is folded into nine rows of U-shaped coil pipe bodies through eight semi-annular folding edges. The U-shaped coil pipe bodies from the second row to the ninth row are sleeved with the fins to form a first fin row, a second fin row, a third fin row, a fourth fin row, a fifth fin row, a sixth fin row, a seventh fin row and an eighth fin row. An upper port and a lower port are formed in the coil pipe. The second connecting pipe and the first connecting pipe are fixedly connected with the upper port and the lower port respectively in a silver soldering mode. The distance d1 between the left side plate and the right side plate ranges from 280mm to 300mm, the distance d2 between the two side plates and the centers of the corresponding semi-annular folding edges close to the two side plates ranges from 20mm to 30mm, and the distance d3 between the upper port and the center of the semi-annular folding edge close to the upper port ranges from 145mm to 160mm. The heat exchange effect of the finned evaporator is better, and after the finned evaporator is assembled according to various installing data, residual impurities can be smaller than or equal to 10.8mg, residual grease dirt can be smaller than or equal to 1.3mg, and residual moisture can be smaller than or equal to 10mg.

Description

technical field [0001] The invention relates to refrigeration equipment, in particular to a finned evaporator. Background technique [0002] Frost-free refrigerators, also known as air-cooled refrigerators, use forced circulation of cold air to control the temperature in the box, and usually use finned evaporators for cooling. The specific setting structure is that the finned evaporator is arranged in the interlayer between the freezer and the refrigerator or at the rear of the box, and a fan is also installed to force the air to flow according to the different needs of the freezer and refrigerator. Adjustment of air volume. However, because of the evaporator, because the use of the evaporator will produce residues, reducing the cooling effect. Contents of the invention [0003] The purpose of the present invention is to provide a finned evaporator with better heat exchange effect and less residue. [0004] The technical scheme for realizing the present invention is as ...
