Description
Technical Field
The invention relates to the technical field of diffusion welding equipment, in particular to a cooling shaft and diffusion welding equipment.
Background
Vacuum diffusion welding is a welding technique for forming a good joint at the interface of a workpiece to be welded by atomic diffusion under certain conditions of temperature, pressure and holding time. Because the welded workpiece is not melted and slightly deformed in the welding process, the method is a solid-phase welding method which is very suitable for constructing a complex inner cavity structure. At present, diffusion welding is widely applied to the fields of electronic industry, nuclear energy industry, aerospace and the like.
Diffusion welding equipment generally comprises a furnace body, a frame, a vacuum system, a hydraulic system, a power supply system, a control system, a cooling system and the like. The cooling system of the diffusion welding equipment is generally formed by reforming a certain air duct according to an air cooling system of a vacuum furnace in the field of the current industry. Different from vacuum brazing and vacuum heat treatment equipment, vacuum diffusion welding workpieces are in a dense accumulation state in a furnace, gaps among the workpieces are small, the furnace loading capacity is large, and a radiating surface is small during cooling. Generally, the charging amount of the vacuum diffusion welding equipment is 2-3 times (by weight) that of the vacuum brazing equipment with the same size. Therefore, heat exchange systems that have been migrated from conventional brazing equipment have not been able to efficiently provide cooling to diffusion welding equipment. In addition, the heat exchanger (copper pipe or copper pipe with fins) of the traditional air-cooled heat exchange system has large volume and high weight compared with the heat exchanger with the same heat exchange amount as the micro-channel heat exchanger due to small heat exchange specific surface area, so that the whole heat exchange system is too fat, the occupied space of equipment is increased, and the industrial development trend of light weight, compactness and high cost performance of diffusion welding equipment is not met. There is an urgent need to find alternatives.
Diffusion bonding equipment has an additional set of pressurization systems due to the need to provide bonding pressure. The pressing shaft of the pressurizing system resists heat conducted in a furnace when the temperature is high (the welding temperature is generally more than 1000 ℃), and a straight-hole water channel is generally arranged in the pressing shaft. Therefore, it is a possible direction to solve the above problems by making full use of the cooling water shaft of the diffusion welding apparatus.
