Problems solved by technology

However, the processing process of T-shaped fins is to use a blade to flatten the vertical outer fins from the top. During the pressing process, the vertical fins subjected to pressure may be bent and deformed, resulting in irregular shapes of T-shaped fins and a cavity structure. The size is not uniform, which affects the heat transfer performance of the evaporator tube

Embodiment 1

[0029] refer to figure 1 , figure 2 Shown is a schematic structural view of the first embodiment of a composite cavity evaporation heat exchange tube of the present invention. In this preferred embodiment, the heat exchange tube includes a tube body 1 with an inner cavity, and the outer surface of the tube body 1 is The outer fins 21 that are distributed in a spiral shape and are integrated with the tube body 1 are provided, and the secondary lateral fins 22 are arranged on one side of the outer fins 21, and the composite fins formed by this structure make the fins The single hole structure between them becomes a compound hole structure, which further increases the vaporization core when the refrigerant evaporates; image 3 As shown, the top of the outer fin 21 is formed into an inclined shape by blade processing, and the inclined direction is consistent with the extending direction of the secondary lateral fin 22 and is inclined to the left, thereby forming an F-shaped oute...

Embodiment 2

[0031] refer to Figure 5 , Figure 6 As shown, it shows a schematic structural view of the second embodiment of a compound hole evaporation heat exchange tube of the present invention. In this preferred embodiment, its basic structure and principle are the same as those of the first embodiment, except that: Figure 7 , Figure 8 As shown, the inclination direction of the fins 21 of the heat exchange tube is consistent with the extension direction of the secondary lateral fins 22 and is inclined to the right; the inclination angle α of the fins 21 is 89°; the secondary lateral fins The included angle β between the sheet 22 and the fin 21 is 89°.

Abstract

The invention provides a composite hole evaporation heat exchange tube. The composite hole evaporation heat exchange tube comprises a tube body and spiral outer fins which are in an integral structurewith the tube body, secondary side fins are arranged on one sides of the outer fins, the top of the outer fins is processed to form an inclined shape, the inclination direction of the outer fins is consistent with the extending direction of the secondary side fins to form a composite spiral channel communicating with gaps between the F-shaped outer fins and the outer fins, the F-shaped outer finsare further processed with fin grooves which are staggered and communicate with the spiral channel, the spiral channel is divided into a plurality of composite hole structures, and inner threaded ribs are arranged on the inner surface of the tube body in a protruding mode. The composite hole evaporation heat exchange tube has the advantages that the composite annular channel formed by the gap ofthe F-shaped outer fins provides a large amount of vaporization cores and is beneficial to rapid growth and rapid overflow of bubbles; and meanwhile, the composite hole structures are beneficial to evaporation of refrigerants in the holes during the evaporation heat exchange process, so that the timely filling of the refrigerants and the effective discharge of steam are ensured, the boiling process is continuous, and the effect of strengthening the boiling heat exchange is achieved.

Description

technical field [0001] The invention belongs to the technical field of evaporative heat exchange tubes in air conditioning and refrigeration systems, and in particular relates to a compound hole evaporative heat exchange tube. Background technique [0002] The evaporative heat exchanger is an essential component in the central air-conditioning system, and the evaporator tube is the core component of the evaporative heat exchanger, and its heat transfer performance determines the performance of the evaporative heat exchanger. For the heat exchange tube manufacturing industry, improving the energy efficiency of refrigeration and air conditioning equipment is mainly achieved by improving the heat exchange efficiency of the heat exchange tube. The evaporator tubes used in refrigeration and air-conditioning systems have relatively large boiling heat transfer resistance and forced convection heat transfer heat transfer resistance when the refrigerant boils outside the tube. There...
