Condenser with variable-toothform internal-thread enhanced tube

Abstract

The invention relates to a condenser with a variable-toothform internal-thread enhanced tube. The condenser with the variable-toothform internal-thread enhanced tube is characterized by comprising more than two first tube sections, more than two second tube sections, more than three connecting elbows and more than two fins, wherein more than three gear racks are uniformly arranged in the axial direction of the inner wall of each first tube section and are spirally distributed; the second tube sections and the first tube sections have the same length; more than three gear racks are uniformly arranged in the axial direction of the inner wall of each second tube section and are spirally distributed; the ratio range of the number of the gear racks of each first tube section to the number of the gear racks of each second tube section is 1-1.5; the ratio range of the spiral angle of each gear rack of each first tube section to the spiral angle of each gear rack of each second tube section is 0.5-1; according to the flowing direction of a refrigerating agent, the connecting elbows communicate every two adjacent tube sections; and each fin is arranged on all the first tube sections and the second tube sections in a sleeving manenr. The condenser with the variable-toothform internal-thread enhanced tube has the advantages as follows: in the whole heat exchanging process of the condenser, the refrigerating agent uses enhanced heat exchanging tubes with different toothforms in different stages, so that the integral heat exchanging effect of the condenser is optimal and thus the performance of a refrigerating system is improved.

Description

technical field [0001] The patent of the present invention relates to an enhanced heat exchange technology for a refrigeration system, especially a variable-tooth internal thread enhanced tube condenser for an air conditioner condenser enhanced heat exchange technology. Background technique [0002] The condenser is one of the key components of the refrigeration system, which has a great influence on the overall performance of the refrigeration equipment. In order to improve the heat exchange effect of the condenser and reduce its material consumption, internally threaded copper tubes are widely used in condensers of refrigeration equipment. In order to improve the heat exchange effect, various internally threaded copper tube manufacturers have developed a variety of toothed internally threaded copper tubes, but one of the basic principles is to increase the heat exchange area in the tube, strengthen the turbulence of the refrigerant in the tube and accelerate the drainage o...

Problems solved by technology

Since the enhanced heat transfer mechanisms of gas-phase heat transfer, gas-liquid two-phase condensation heat transfer, and liquid-phase heat transfer are different, gas-phase enhanced heat transfer is mainly to enhance the turbulence of the refrigerant in the tube, increase the heat transfer area and reduce the flow rate. resistance, while the liquid-phase enhanced heat transfer is mainly to enhance the turbulent flow of the refrigerant in the tube and increase the flow rate of the refrigerant. Obviously, the use of a tooth-shaped internal threaded copper tube for enhanced heat transfer in these three stages cannot achieve the best performance of the condenser. Heat transfer effect
