A corrugated hair-fin condenser

Abstract

The invention relates to a corrugated hair-fin condenser, which comprises a hair-fin, a condenser tube and a fixed bracket; the outer wall of the condenser tube is helically wound with hair-fins at an equal pitch, and the fixed bracket is fixedly connected to the outer edge of the hair-fin; The fur fins are integrally stamped from strip-shaped metal sheets, and the fur fins are uniformly stamped with several crease lines perpendicular to the length direction of the strip-shaped sheets, and the strip-shaped sheets between two adjacent crease lines There is a tangent line on the top, the tangent line is parallel to the crease line, and the upper and lower ends of the tangent line are respectively close to the upper and lower long sides of the strip-shaped sheet, and the fur fins are bent through the crease lines to form a wave-shaped structure; the inventive fin manufacturing The process is simple and the manufacturing cost is low. While increasing the heat dissipation area of ​​the fins to increase the heat exchange area with the air, it also accelerates the turbulent flow of the air between the fins and improves the cooling effect and heat exchange rate.

Description

technical field [0001] The invention relates to a refrigeration and heat dissipation device, in particular to a corrugated hair-fin condenser. Background technique [0002] Existing refrigerator condensers are divided into wire tube condensers and spiral fin condensers; wire tube condensers are welded with steel wires and steel pipes as a whole, as heat exchange components, and wire tube condensers as direct cooling The main heat exchange components of the direct cooling type (with frost) refrigerator have been mainly purchased by consumers, and its market price is low, so it occupies a certain market share. However, there are some problems in the direct cooling type refrigerator: the internal temperature drops The process depends on the natural circulation of air, the cooling capacity is poor, frost will form when the volume is small, and the internal temperature of the refrigerator fluctuates greatly; the traditional way to increase the cooling capacity is to improve the s...

Problems solved by technology

[0002] Existing refrigerator condensers are divided into wire tube condensers and spiral fin condensers; wire tube condensers are welded with steel wires and steel pipes as a whole, as heat exchange components, and wire tube condensers as direct cooling The main heat exchange components of the direct cooling type (with frost) refrigerator have been mainly purchased by consumers, and its market price is low, so it occupies a certain market share. However, there are some problems in the direct cooling type refrigerator: the internal temperature drops The process depends on the natural circulation of air, the cooling capacity is poor, frost will form when the volume is small, and the internal temperature of the refrigerator fluctuates greatly; the traditional way to increase the cooling capacity is to improve the structure of the wire tube pipeline or increase the number of steel wires, and increase the capacity of the condenser Heat exchange area, improving performance generally starts with improving the length of the steel pipe or increasing the number of steel wires, increasing the number of arrangements of the pipeline to increase the length of the pipeline, increasing the number of steel wires by increasing the spacing of the steel wires, and adjusting the structure leads to complex production and processing processes and increased product weight , the reliability of product quality is reduced, and the production cost is increased;

[0003] Spiral-fin condensers generally use strip steel with a width of 3-10mm and a thickness of 0.5mm to be wound onto the condenser tube and the outer surface of the evaporator through tooling. It is currently mainly used on air-cooled refrigerators, and is gradually pursuing environmental protection in the market. Under the general trend, air-cooled refrigerators are gradually replacing direct-cooled refrigerators, occupying a certain proportion in the field of high-end refrigerators; but because the strip steel is wound to the surface of the condenser tube and evaporator, the distance between the spirally wound strip steel is small, As a result, the air circulation between the spiral sheets will be affected, thereby affecting the heat transfer efficiency
