Abstract
The invention relates to a magnesium alloy and copper die-casting composite heat radiator, comprising a magnesium alloy body, wherein a copper water channel insert which is connected with the magnesium alloy body into a whole through die casting compositing is arranged in the magnesium alloy body; the copper water channel insert comprises an upper pipe joint, a lower pipe joint and a copper pipe connected between the upper pipe joint and the lower pipe joint, and anti-corrosion inner pipes are arranged on the inner walls of the upper pipe joint, the lower pipe joint and the copper pipe. The body of the magnesium alloy and copper die-casting composite radiator is made of magnesium alloy, therefore, the body is light in weight, high in strength, and low in cost; the built-in water channel insert is made of copper, and the anti-corrosion inner pipes are arranged on the inner wall of the water channel insert, therefore, the built-in water channel insert has a good anti-corrosion performance and a long service life; as being molded in a die-casting mold in a high-temperature liquid state, the magnesium alloy is high in material density, sturdy and durable, and has no welding spot and area on surface; and the built-in water channel insert and the body are sequentially die-casted and inserted, the strength of the insert is high, and the combination of the magnesium alloy and the copper is reliable.
Description
Technical field
The present invention relates to the radiator field, relate in particular to a kind of magnesium alloy-copper die casting composite heating radiator.
Background technology
The heating system that the northern China most of areas generally adopts radiator, boiler body, pipe-line system and high-temperature-hot-water heating agent (or steam) to constitute solves people's heating problem, antagonism severe cold.As the radiator of heating system end equipment, traditional have cast-iron radiator, a steel radiator.As everyone knows, cast-iron radiator is heavy, presentation quality is poor, so people adopt steel radiator to replace cast-iron radiator.But steel radiator antioxygen corrosive power is poor.Because China urban heating system is main with central heating mainly; A lot of heating system design Selection normal-pressure boiler direct heating or selected the open type expansion tank for use or selected the constant pressure pump level pressure for use and automatic drainage system etc.; This non-enclosed heating system constantly discharges water and moisturizing, makes ducted oxygen content severe overweight; In addition because the management existing problems; Parts such as valve in bad repair with age or that select for use are defective or appearance lack of standardization is installed leaks in a large number; The hot water of missing has only through replenishing cold water realizes balance, and this has more increased ducted oxygen content, so steel radiator is shorter service life.For remedying the deficiency of steel radiator antioxygen corrosive power difference, people are employed in the passive mode that the steel radiator inner chamber is coated with chemical preservation coating, are coated with the thickness and the uniformity of attaching but can't detect coating, therefore are coated with to attach the very difficult assurance of quality.Because aluminium has the antioxygen corrosive power that changes strong; Therefore people adopt Aluminium Radiator again a few years ago; But aluminium alkali resistance corrosive power is very poor, only is applicable to the heating water quality of PH=5-8.5, is not suitable for the current widely used open type boiler direct supply system of China (PH=10-12).Copper is a kind of antioxygen corrosive power and all very strong material of alkali resistance corrosive power, so the copper radiator long service life.
Summary of the invention
The technical problem that the present invention will solve is: provide a kind of in light weight, intensity good, good corrosion resistance, the long magnesium alloy-copper die casting composite heating radiator of sturdy and durable, physical life.
In order to overcome the defective that exists in the background technology; The technical solution adopted for the present invention to solve the technical problems is: a kind of magnesium alloy-copper die casting composite heating radiator; Comprise the magnesium alloy body; Be provided with copper water channel inserts in the said magnesium alloy body; Said magnesium alloy body and copper water channel inserts link into an integrated entity through die casting is compound, and said copper water channel inserts comprises pipe joint, lower pipe connection and be connected the copper pipe between pipe joint, the lower pipe connection that said upward pipe joint, lower pipe connection, copper pipe inwall are provided with pipe in the anticorrosion.
According to another embodiment of the invention, a kind of magnesium alloy-copper die casting composite heating radiator comprises that further said upward pipe joint, lower pipe connection are provided with connecting hole, and weld with connecting hole respectively at said copper pipe two ends.
According to another embodiment of the invention, a kind of magnesium alloy-copper die casting composite heating radiator comprises that further said magnesium alloy body is provided with fin.
According to another embodiment of the invention, a kind of magnesium alloy-copper die casting composite heating radiator comprises that further said magnesium alloy body is provided with the shutter port.
According to another embodiment of the invention, a kind of magnesium alloy-copper die casting composite heating radiator comprises that further pipe closely is cast into one with last pipe joint, lower pipe connection, copper pipe in the said anticorrosion.
The invention solves the defective that exists in the background technology, body is a magnesium alloy, and it is in light weight, intensity good, cost is low; The built-in water passage inserts is a copper material, and is provided with in the anticorrosion at water channel inserts inwall and manages its corrosion resistance and good, long service life; Magnesium alloy is shaped in die casting under high-temperature liquid state, and material density is big, and the surface does not have welding processing stand face, and is sturdy and durable; Built-in water passage inserts and body be the embedding of die casting bag successively, and inserts intensity is high, and magnesium alloy and copper combine reliable.
