Abstract
The utility model discloses a copper and steel composite pipe assembly. The copper and steel composite pipe assembly comprises a gas dividing main pipe and N gas dividing branch pipes, wherein the N gas dividing branch pipes are communicated with the gas dividing main pipe, the gas dividing main pipe is a copper and steel composite pipe, the middle layer of the gas dividing main pipe is made of steel, the inner layer of the gas dividing main pipe and the outer layer of the gas dividing main pipe are made of copper, the gas dividing main pipe is connected with the gas dividing branch pipes through brass welding flux in a welded mode, the gas dividing branch pipes are copper pipes, a sealing cap is arranged on the pipe opening at one end of the gas dividing main pipe, the sealing cap is welded on the pipe opening of the gas dividing main pipe through brass welding flux, and the N gas dividing branch pipes are perpendicular to the gas dividing main pipe and arranged on the gas dividing main pipe in parallel. The copper and steel composite pipe assembly is simple in structure and good in thermal conductivity, prevents corrosion, is high in intensity, saves the copper resources, is low in manufacturing cost and is beneficial to sustainable development.
Description
Technical field
The utility model belongs to refrigeration technology field, is specifically related to a kind of copper steel composite tubular assembly.
Background technology
In the prior art, be used for refrigerating and heating device, heat exchanger on the refrigeration plants such as air-conditioning generally all is connected with the gas-distributing pipe assembly, it is in order to optimize flow passage structure that the gas-distributing pipe assembly is set, reach the purpose of sufficient heat exchange, because copper has very high heat conductivity and corrosion resistance, existing gas-distributing pipe assembly generally all is to adopt copper pipe, but copper price comparison height, the copper resource scarcity, under the rare day by day situation of copper material resource, also be unfavorable for control and the sustainable development of cost, and bulk strength is not enough, yielding, if it is then perishable to substitute copper pipe with the straight carbon steel pipe, need a kind of energy low cost of manufacture badly, and thermal conductivity is good, corrosion-resistant, the gas-distributing pipe assembly that intensity is higher.
The shortcoming of prior art is: existing gas-distributing pipe consumes that copper material is more, cost is than higher, and bulk strength is not high enough, yielding.
The utility model content
The purpose of this utility model is to provide a kind of copper steel composite tubular assembly can save the copper resource, makes low cost of manufacture, and thermal conductivity is good, corrosion-resistant, intensity is higher.
For achieving the above object, the technical solution of the utility model is as follows: a kind of copper steel composite tubular assembly comprises that branch gas is responsible for and is responsible for the N root that is communicated with minute gas and divides gas branch pipe that its key is: it is the copper steel multiple tube that described minute gas is responsible for.
After adopting the copper steel multiple tube, can increase the intensity that branch gas is responsible on the one hand, also guarantee on the other hand to divide the gas person in charge's high-termal conductivity and stronger corrosion resistance, reduce manufacturing cost simultaneously.
It is that the intermediate layer is that steel, internal layer and skin are the copper steel multiple tube of copper that described minute gas is responsible for.
Adopt said structure, divide gas to be responsible for copper steel multiple tube instead of copper pipe manufacturer, hardness and intensity that middle steel layer can make branch gas be responsible for improve, the copper of internal layer has good thermal conductivity simultaneously, be convenient to heat exchange, internal layer and outer copper have corrosion resistance, can prevent that the branch gas person in charge is corroded.
Described minute gas branch pipe and divide gas to weld by strong solder between being responsible for.
After dividing gas to be responsible for employing copper steel multiple tube, and do not reach requirement with welding such as original copper phosphorus scolders between minute gas branch pipe, can reach optimum efficiency and adopt strong solder to weld.
Described minute gas branch pipe is copper pipe.
Owing to divide gas branch pipe shorter and smaller, still can adopt original copper pipe.
Described minute gas is responsible for an end mouth of pipe sealing cap is installed, and this sealing cap is welded on branch gas by strong solder and is responsible on the mouth of pipe.
This sealing cap can be that the copper material also can be copper-steel composite material, and strong solder makes sealing cap and divides and weld better between the gas person in charge.
Described minute gas branch pipe of N root is vertical with the branch gas person in charge, and is arranged side by side on minute gas is responsible for.
The beneficial effects of the utility model are: simple in structure, thermal conductivity is good, corrosion-resistant, intensity is high, saves the copper resource, and low cost of manufacture is beneficial to sustainable development.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of copper steel composite tubular assembly, comprise the branch gas person in charge 1 and be responsible for 1 seven branch gas branch pipes 2 that are communicated with minute gas, seven branch gas branch pipes 2 are with to divide gas to be responsible for 1 vertical, and be arranged side by side at minute gas and be responsible on 1, it is that the intermediate layer is that steel, internal layer and skin are the copper steel multiple tube of copper that described minute gas is responsible for 1, dividing gas branch pipe 2 is copper pipe, divide between gas branch pipe 2 and the branch gas person in charge 1 by strong solder 3 welding, divide gas to be responsible for the 1 one end mouths of pipe sealing cap 4 is installed, this sealing cap 4 is welded on the branch gas person in charge 1 the mouth of pipe by strong solder 3.
