Abstract
Description
Technical Field
[0001] The utility model relates to the field of metal processing, and particularly relates to a ventilation rotating head. Background Art
[0002] With the advent of the 5G era, the data transmission volume of high-power electronic devices, base stations, servers, etc. has doubled. When the internal electronic components work, they generate serious heat. The heat dissipation problem of the devices seriously affects the service life of the components and also determines whether they can be applied in the field of high-end products. Oxygen-free copper, especially high-purity oxygen-free copper (oxygen content ≤ 10 ppm), is used to produce heat dissipation devices with high heat transfer capacity due to its extremely high electrical and thermal conductivity.
[0003] However, oxygen-free pure copper has problems such as low strength and low recrystallization temperature, which easily lead to problems such as rapid grain growth and surface defects of products during subsequent plastic processing and heat treatment. In response to this problem, various studies and discussions have been carried out in the industry in recent years. Attempts have been made to improve the tensile strength, hardness, elongation, and electrical conductivity of oxygen-free copper in the high-temperature sintered state by adding various trace elements. At present, oxygen-free copper materials strengthened with trace rare earth oxides have been developed.
[0004] However, in actual production, due to the low density of the alloy, floating is likely to occur during casting, resulting in uneven tissue properties of the finished product. Moreover, when casting microalloys, it is very easy to block the injection holes, posing serious safety hazards. So far, the industry does not have the ability to mass-produce, and the tissue properties of the products need to be improved. If the problems in the existing technology need to be overcome, it is necessary to use a mixer during the production of oxygen-free copper materials strengthened with trace rare earth oxides. However, the ventilation rotating head of the existing mixer is difficult to solve the problems of the existing technology. Therefore, a ventilation rotating head that can realize the ventilation function, stirring function, enable the inert gas to disperse into the copper liquid, and enable the copper liquid to have a certain up and down tumbling so that the alloy material is more uniform in the copper liquid is needed. Summary of the Utility Model
[0005] The main purpose of the utility model is to provide a ventilation rotating head that can realize the ventilation function, stirring function, enable the inert gas to disperse into the copper liquid, and enable the copper liquid to have a certain up and down tumbling so that the alloy material is more uniform in the copper liquid.
[0006] The utility model provides a ventilation rotating head, which includes an inner rotating member, an outer rotating member, and a plurality of intermediate connectors;

[0008] An air outlet channel is provided inside the intermediate connecting member. An air inlet hole corresponding to the air outlet channel is provided on the side surface of the inner rotating member. An air outlet hole corresponding to the air outlet channel is provided on the outer rotating member. The air inlet hole and the air outlet hole are connected through the air outlet channel.
[0009] The ventilation rotating head can be driven to rotate through the rotating arm, so that the function of stirring can be realized through the ventilation rotating head. The inert gas output inside the rotating arm can be output successively through the air inlet hole, the air outlet channel and the air outlet hole, so that the inert gas can be diffused into the copper liquid.
[0010] Preferably, both the ventilation rotating head and the rotating arm are made of graphite.

[0013] Preferably, an inclined surface is provided at the bottom of the air outlet channel. By setting the inclined surface, the angle of the inert gas leaving the ventilation rotating head can be changed, so that the copper liquid can have a certain up and down tumbling, making the alloy material more uniform in the copper liquid.

[0015] The beneficial effects of the ventilation rotating head of the present utility model are as follows:
