Efficient tube-fin-type condenser device and using method thereof

Abstract

The invention relates to an efficient tube-fin-type condenser device and a using method thereof. In an existing condenser, a great amount of condensing tube bundles are arranged in the cylinder, so that a gaseous refrigerant cannot fully and effectively contact with all the outer surfaces of the condensing tube bundles, the condensing process is insufficient, the energy efficiency is reduced, and the utilization rate of the condensing tube bundles is low. The invention adopts the technical scheme that the efficient tube-fin-type condenser device adopts a structure comprising an efficient tube-fin assembly and support baffle plates so as to ensure that a gas-phase refrigerant is condensed into a liquid directionally and quickly in a baffling manner, so that not only the effective heat-transfer area but also the flow velocity of the gaseous refrigerant in the cylinder of the condenser are increased, the heat energy efficiency of the condenser is effectively improved, and the super-cooling effect is obvious, wherein the efficient tube-fin assembly is composed of reinforcing heat-transfer fins. Compared with a traditional shell-tube-type condenser, the efficient tube-fin-type condenser device is relatively small in size and relatively high in efficiency; the energy efficiency is increased by 30-50% when compared with that of an existing condenser. The efficient tube-fin-type condenser device is compact in structure, convenient to manufacture and mount and low in processing cost, and saves energy.

Description

technical field [0001] The invention relates to a condenser device in refrigeration equipment, in particular to a high-efficiency tube-fin condenser device and its use method. Background technique [0002] Refrigeration and air conditioning are widely used in daily life. The cylindrical condenser is the main part of the refrigeration system. It is composed of a cylinder, a condensing tube bundle, a support plate, a tube plate at both ends, a tube box, a support and a corresponding connecting pipe. The gaseous refrigerant in the cylinder Whether it can be condensed quickly and effectively depends on the optimization of the internal structure of the condenser and the utilization of the condensing tube bundle. [0003] In the manufacturing process of shell-and-tube condensers, the structural forms commonly used at present still have the following defects: 1) Due to the insufficient heat exchange process of the gaseous refrigerant in the condenser cylinder, the supercooling eff...

Problems solved by technology

[0003] In the manufacturing process of shell-and-tube condensers, the structural forms commonly used at present still have the following defects: 1) Due to the insufficient heat exchange process of the gaseous refrigerant in the condenser cylinder, the supercooling effect is not obvious, resulting in Thermal performance declines; 2) Although the existing tube-and-tube structure uses efficient condensing tube bundles, due to the limitation of the tooth shape, there are still many condensing tube bundles arranged in the condenser cylinder, so that the gaseous refrigerant cannot be fully effective All contact with the outer surface of the condensing tube bundle, resulting in insufficient condensation process and reduced energy efficiency, resulting in low utilization rate of the condensing tube bundle, high cost, uneconomical and energy-saving
