Abstract
When two kinds of metal or alloy are made into composite material by using hot-working methods, such as casting or rolling, etc., one of the metal or alloy is melting; even if the temperature of the metal of the alloy is lower than the melting point of the other kind of non-melting metal, when the metal and the alloy are in contact, the alloy is dissolved in the metal because of alloying. In manufacturing an embedding copper pipe type liquid (water) cold aluminum coil or aluminum row, the copper pipe and the aluminium form low-melting aluminium bronze, and the copper pipe is caused to be burnt through to lead into water leakage. The utility model is characterized in that an isolating layer is added between two kinds of metal, which prevents the copper pipe from being burnt through because of alloying.
Description
With two kinds of different metals or alloy with casting or hot-working method such as roll, when making composite, wherein a kind of metal or alloy is what melt, even its temperature is lower than the another kind of not fusing point of deposite metal, when the two contacted, the latter still can be dissolved in the former because of " alloying ".
When imbedding copper pipe formula liquid (water) cold aluminium coil or aluminium row as manufacturing, can because of copper pipe and aluminium forms low-melting aluminium bronze and make copper pipe burn leakage (water).
Feature of the present utility model is: in making the composite material element process, between molten metal or alloy (1) and molten another metal (2), increase a separation layer (3), as Fig. 1, outside copper pipe (2), plate high melting metal layer nickel or chromium as separation layer (3), also available enamel, waterglass or glass or its fibre.Adjust the effect of thermal resistance between cooling water in the pipe and the outer metallic conductor of pipe in addition with these materials, under effective cooling condition, with the minimizing in-tube fouling, prevent the conductive surface dewfall.
Use this technology, can make the bus-bar that cast aluminium buries the big electric current water cooled coil of copper pipe or silicon rectifier cell is installed, and be used to make the one-sided interior water-cooled transformer of low-voltage, high-current.
Claims (4)
1, by two kinds of different metals or alloy, wherein a kind of is melt.To cast or to roll the composite members that class methods are made, it is characterized in that: between the contact-making surface of two kinds of metal or alloy, a separation layer is arranged.
2, by the product of claim 1 regulation, when a kind of metal is an aluminium, when another is copper, it is characterized in that: separation layer is the refractory metal coating on the copper pipe outer wall.
3, by the product of claim 1,2 regulations, it is characterized in that: separation layer is nickel or chrome plating.
4, by the product of claim 1 regulation, it is characterized in that: separation layer is enamel, waterglass, glass or its fibre.
