Abstract
The utility model discloses a seamless high finned pipe made of copper and copper alloy for heat exchangers. The seamless high finned pipe is composed of a copper pipe and high fins wound on the pipe body in helical type at the outer circumference of the copper pipe. The high finned pipe is once formed in rolling by a three-high mill. The height of the high fins can reach 20 mm. The high fins and the main pipe are an integral structure and are adhered in a non-bonding method or other methods. The utility model is suitable for the fields of electric force, energy resource, chemical industry and home appliances.
Description
Technical field
The utility model relates to a kind of radiating tube, especially relates to a kind of heat exchanger with copper and the seamless high finned tube of copper alloy.
Background technology
Along with developing rapidly of science and technology, require heat exchanger to develop to efficient, energy-conservation, miniaturization, environmental protection direction, this also just requires the heat exchanger copper pipe, has characteristics such as fast, high-effect, the environmental protection of conducting heat, energy-conservation, high accuracy.At present, heat exchanger copper pipe on the domestic market mostly adopts metal light pipes such as simple copper, aluminium, or with the method for welding radiating fin is fixed on the excircle of light pipe.The radiating tube that also has then adopts riffled tube or low tooth pipe, and the shortcoming of above-mentioned this radiating tube is that radiating efficiency is low, manufacturing cost is high.
Summary of the invention
The purpose of this utility model is to provide a kind of advanced and reasonable design at the existing shortcoming of above-mentioned radiating tube, and the high heat exchanger of new generation of heat transfer efficiency is with copper and the seamless high finned tube of copper alloy.
For achieving the above object, the utility model has mainly adopted following technical scheme to realize.The utility model is made up of copper and the seamless female pipe of copper alloy, on the excircle of seamless female pipe, be provided with helical form and twine the high fin of body, described high fin is to adopt three-high mill to revolve to roll one-shot forming, high fin and seamless female pipe are structure as a whole, non-welding or employing alternate manner are bonding, and the height of high fin can reach 20mm.
The utility model compared with prior art has following obvious advantage and progress.(1) the utility model adopts three-high mill to revolve to roll one-shot forming, and fin height can reach 20mm, and fin density is big, and wing is apart from little, and fin is thin, characteristics such as that product has is efficient, energy-conservation, durable, environmental protection, material-saving.(2) the utility model product rigidity is strong, and anti-seismic performance is good.(3) heat transfer coefficient of the present utility model be light pipe 2.5-3.5 doubly, compare with other low finned tube heat exchanger with volume equipment, exchange capability of heat can improve more than 25%.
The utility model is applicable to electric power, the energy, chemical industry and field of household appliances.
Below in conjunction with drawings and embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 cuts open for the utility model overall structure and shows schematic diagram.
Fig. 2 is the utility model partial cutaway diagrammatic sketch.
The specific embodiment
As shown in Figure 1, the utility model is made up of copper and 1 of the seamless female pipe of copper alloy, on the excircle 2 of seamless female pipe 1, be provided with helical form and twine the high fin 3 of body, described high fin 3 is to adopt three-high mill to revolve to roll one-shot forming, high fin 3 is structure as a whole with seamless female pipe 1, non-welding or employing alternate manner are bonding, and the height of high fin 3 reaches 20mm.
As shown in Figure 2, be provided with the high fin 2 that helical form is twined body on the excircle 2 of seamless female pipe 1, the height of high fin 2 reaches 20mm.
The utility model is applicable to electric power, the energy, chemical industry and field of household appliances.Be specially adapted to the heat exchanger industry.
Claims (2)
