Direct flow type fin evaporator

Abstract

The invention discloses a direct flow type fin evaporator which comprises evaporation pipelines and fins. One ends of the evaporation pipelines on the direct flow type evaporator are horizontally parallel, and the other ends of the evaporation pipelines on the direct flow type evaporator are folded outwards, made horizontal and then folded outwards till being cycled to the root portions of the evaporation pipelines. The side faces of the evaporation pipelines from the heads to the root portions are of an inverted-V-shaped structure in the longitudinal direction, and the adjacent evaporation pipelines are vertically staggered in the transverse direction. The formed evaporation pipelines are pushed into the well-fixed fins and end plates to be fixed together through pipe expanding equipment. The pipelines at the horizontally parallel ends of the evaporation pipelines are provided with a liquid storage device and connected with an inlet pipe orifice, and the root portions of the evaporation pipelines are connected with an outlet pipe. The fins are provided with fin holes for installing the evaporation pipelines. The fin holes are parallel, and the adjacent fin holes are staggered in the left-right direction. The end plates are provided with end plate holes for installing the evaporation pipelines. The end plate holes are parallel, and the adjacent fin holes are staggered in the left-right direction. The relative positions and flanging directions of the end plate holes are consistent with those of the corresponding fin holes.

Description

technical field [0001] The invention relates to a downstream finned evaporator, which is especially suitable for use on air-cooled refrigerators. Background technique [0002] In modern life, refrigerators are increasingly becoming a necessity in home life. There are two common types of refrigerators: direct-cooling refrigerators and air-cooling refrigerators. Comparison of direct-cooling refrigerators and air-cooling refrigerators: direct-cooling refrigerators have a simple structure and are easy to manufacture; the cooling speed is fast; in the case of a reasonable design structure, the power consumption is lower than that of air-cooled refrigerators and the price is cheaper, but the freezer needs to be cleaned regularly. Frost; the temperature uniformity in the box is not good; the temperature of each room cannot be adjusted independently. Although the air-cooled refrigerator has a more complex structure than the direct-cooled refrigerator, the cost is also higher, and ...

AI Technical Summary

Problems solved by technology

[0004] The auxetic finned evaporator has more sufficient heat exchange and relatively simple processing technology because the evaporating tube and fins are in a circular fit, but because of the large number of sheets used, the processing efficiency is not high, and there are more solder joints than push-in products. , the risk of leakage is greater, and the in-line structure occupies a larger space in the refrigerator; the contact surface between the evaporating tube and the fin of the push-in fin evaporator is semicircular, so the heat exchange is not sufficient, but its pipeline has With a certain inclination angle, when the internal volume is constant, the space occupation rate is small, the solder joints are less than those of the auxetic type, and the processing technology is relatively simple. It is often used in finned evaporators.
