Abstract
A novel steel radiator comprises an upper steel header tube, a lower steel header tube, multiple copper or stainless steel liner tubes and aluminum profile cooling fins installed outside all the liner tubes. Steel water nozzles are welded to connecting positions of the steel header tubes and the two ends of each liner tube. Each steel water nozzle is pressed into two end holes of the corresponding liner tube in an interference fit mode. The novel steel radiator has the advantages that the water nozzles are aligned with inner holes of the copper or stainless steel liner tubes to be pressed into the liner tubes for forming connection by the adoption of a hydraulic machine in the interference fit mode, and therefore safety is very high. According the material and structure of the novel radiator, the internal corrosion problem of the steel radiator is solved, besides, the problems that a copper-aluminum composite radiator is high in price and low in mechanical strength are solved, the production technology is greatly simplified, production efficiency is improved, and the novel steel radiator is suitable for production in large batch.
Description
Technical field
The utility model relates to a kind of Novel steel radiator.
Background technology
Development in recent years faster composite copper aluminium radiator is handsome in appearance various, is received by the market.But copper material price constantly rises violently at present, cost is higher, it is the bottle diameter of its development, and the structure of general composite copper aluminium radiator as shown in Figure 1, welding (brazing weld bond 4) several copper internal lining pipes 2 between the copper perpendicular box pipe 1 of upper and lower side, at the outer installation aluminium section bar of copper internal lining pipe 2 fin 3.Also there are some shortcomings in its processing technology and structure problem, in order to reduce cost, need to reduce the use amount of copper material, general copper connecting leg (copper pipe between copper internal lining pipe 2 and copper perpendicular box pipe 1) thickness of pipe wall is 0.8mm left and right, the wall thickness of copper internal lining pipe 2 is 0.5-0.6mm, and general technology is that perpendicular box pipe 1 is taked gas welding welding with internal lining pipe 2.Because the characteristic of copper material is that (after welding) hardness significantly reduces after material heating, make its mechanical strength decay, when pipeline is connected with radiator in radiator installation process, need use screwed connection, when afterburning with spanner, the root of copper internal lining pipe 2 easily produces distortion.
Utility model content
The purpose of this utility model is just to provide a kind of Novel steel radiator, high to solve the copper material price that prior art exists, and the root of copper internal lining pipe easily produces the problem of distortion while being connected with pipeline.
The technical solution of the utility model is: comprise steel perpendicular box pipe, internal lining pipe and aluminium section bar fin, at the two ends up and down of several internal lining pipes, respectively connect a steel perpendicular box pipe, at each internal lining pipe, aluminium section bar fin is housed outward, it is characterized in that: in the junction at described steel perpendicular box pipe and each internal lining pipe two ends, be respectively welded with a steel water nozzle, each this root steel water nozzle interference fit is pressed into interior connection of two stomidiums of described internal lining pipe, it is 3.2～3.5mm that described perpendicular box pipe adopts wall thickness, the seamless cold drawing steel tube of tensile strength sigma b=480Mpa is made, described water nozzle wall thickness is 3mm.
Described internal lining pipe is made by copper pipe or stainless steel tube.
Between described aluminium section bar fin and internal lining pipe and steel water nozzle for interference is connected.
The utility model has the advantages that: the endoporus of aiming at copper internal lining pipe or stainless steel inner lining tube with water nozzle adopts interference fit of hydraulic press to be pressed into moulding connection, interface is the water-tight suitable tensile strength that also has, through the interior compacting that repeatedly pressure is 15-20Mpa, test, harmless to radiator the slightest, and radiator when reality is used in pressure only have 0.5-0.8Mpa.Therefore this syndeton in use safety coefficient be 25 times of actual use, there is extraordinary security.This kind of new radiator by material and structure, both overcome the interior Anticorrosion of steel radiator, solved again the higher and low problem of mechanical strength of composite copper aluminium radiator price, greatly simplified production technology, improved production efficiency, be suitable for producing in enormous quantities.
Accompanying drawing explanation
Fig. 1 be prior art structural representation;
Fig. 2 is the utility model general structure schematic diagram.
The specific embodiment
Referring to Fig. 2, the utility model comprises upper and lower two steel perpendicular box pipes 1, several copper or stainless steel inner lining tube 6 and is arranged on the aluminium section bar fin 3 outside every internal lining pipe 6, in described steel perpendicular box pipe 1 and the junction at each internal lining pipe 6 two ends, be respectively welded with a steel water nozzle 5, each these root steel water nozzle 5 interference fit is pressed in two stomidiums of described internal lining pipe 6.
Described steel perpendicular box pipe 1 adopts the seamless cold drawing steel tube that wall thickness is 3.2～3.5mm, and its mechanical strength is high, tensile strength sigma b=480Mpa.About the interior antiseptic property of heating installation, when the general water pipe wall thickness of national regulation reaches 2.5mm, can not do interior anticorrosionly, and the wall thickness of steel perpendicular box pipe 1 of the present utility model is 3.2～3.5mm, surpasses national standard many, therefore in anticorrosion not being a problem.Between steel perpendicular box pipe 1 and steel water nozzle 5, adopt argon arc welding welding, the wall thickness of steel water nozzle 5 is 3mm, and postwelding mechanical strength improves more than 10 times than copper pipe welding.Perpendicular box pipe 1 and the aluminium section bar fin 3 of this radiator is to adopt interference fit plunging once to press-fit, and with the endoporus of steel water nozzle 5 aligning coppers or stainless steel inner lining tube 6, adopts hydraulic press to be once pressed into moulding.Owing to can selecting the suitable magnitude of interference, after being therefore pressed into, be the water-tight suitable tensile strength that also has.We repeatedly carry out the interior compacting of interior pressure 15～20Mpa and test, harmless to this radiator the slightest.And this radiator is pressed in when reality is used and only had 0.5～0.8Mpa, therefore this syndeton safety coefficient is in use 25 times of actual use, is perfectly safe.This kind of new radiator by material and structure, both overcome the interior Anticorrosion of steel radiator, solved again the higher and low problem of mechanical strength of composite copper aluminium radiator price, and this structure is suitable for assembling and produces, work efficiency is high, is suitable for large-engineering batch production.
