Problems solved by technology

However, the liquid flow formed by the cooling liquid and the air flow generated by the inert gas in the protective tube act on the welding strip, which still affects the strip speed of the welding strip. If the strip speed is high, the welding strip will vibrate violently, thus affecting the hot dip coating of the previous sequence. cover
In addition, during the operation of the device, it is still necessary to consume inert gas and increase the operating cost

Abstract

The invention relates to a wire rod cooling device. The wire rod cooling device comprises a cooling cylinder and an inner pipe, wherein the cooling cylinder is provided with an inner cavity, the innercavity is used for loading cooling liquid, and a wire inlet and a wire outlet are formed in the lower end and the upper end of the cooling cylinder correspondingly; and the periphery of the upper endof the inner pipe is connected to the periphery of the wire outlet in a sealed mode, a wire passing channel is formed in the inner pipe, and the lower end of the inner pipe extends towards the wire inlet; and an extraction opening is further formed in the cooling cylinder and communicates an the inner cavity between the outer wall of the inner pipe and the inner wall of the cooling cylinder. Thebelt speed of a wire rod can be increased.

Description

technical field [0001] The invention relates to a wire rod cooling device, which is used for cooling photovoltaic soldering strips after being tinned, and can also be used for cooling other wire rods. Background technique [0002] Photovoltaic welding ribbon is tinned copper strip, which is used in the connection of photovoltaic module cells and is an important raw material in the welding process of photovoltaic modules. [0003] When the photovoltaic ribbon is tinned, it has to pass through a tin melting furnace at 230 degrees Celsius. After the ribbon passes through the tin furnace, the temperature can reach more than 100 degrees Celsius, and it needs to be cooled before it can be wound. And the cooling treatment can make the tin layer more uniform and adhere firmly. In reality, cold air cooling and liquid nitrogen cooling are usually used. [0004] Among them, cold air cooling usually uses inert gas and air-conditioning refrigeration, which has the disadvantages of high...
