First, the connection method between the copper tube and other parts of the water cooling plate needs to be carefully designed. Welding is one of the commonly used connection methods. High-quality welding process can ensure the close integration between the copper tube and the connecting parts. For example, argon arc welding can provide stable welding quality, because the protection of argon gas can prevent the copper tube from oxidizing during welding, making the weld more firm and sealed. Before welding, make sure that the surface of the copper tube and the connecting parts is clean, free of impurities such as oil, oxide layer, etc., which can improve the adhesion of welding and reduce the possibility of gaps.
Secondly, the selection of sealing materials is the key. Suitable sealants or sealing gaskets can effectively fill tiny gaps. For copper tube water cooling plates, sealing materials that are resistant to high temperature and coolant corrosion should be selected. For example, fluororubber sealing gaskets have good chemical corrosion resistance and elasticity, can maintain good sealing performance under different temperature environments, and effectively prevent coolant from leaking from the interface.
Furthermore, the overall structural design of the water cooling plate will also affect the sealing. Reasonable layout can reduce the damage of seals caused by thermal expansion and contraction or vibration. For example, a certain amount of expansion and contraction space is reserved during design to cope with the expansion and contraction of copper tubes when the temperature changes, so as to avoid the copper tubes and surrounding parts from squeezing and causing the seals to loosen.
During the assembly process, the operation specifications must be strictly followed. Ensure that each connection is properly installed and the sealing materials are placed in place and evenly. For the parts where sealant is used, pay attention to the thickness of the glue layer and the uniformity of the application to avoid the glue layer being too thick or too thin to affect the sealing effect. At the same time, after the assembly is completed, appropriate pressure tests should be carried out. Check for leaks by injecting a certain pressure of gas or liquid into the water-cooled plate.
Daily maintenance should not be ignored either. Regularly check the sealing parts of the water-cooled plate to see if there are any signs of coolant leakage or signs of aging of the sealing material. If a small leak is found in the seal, timely measures should be taken to repair it, such as replacing the sealing gasket or reapplying the sealant.
In addition, some auxiliary sealing measures can also be adopted. For example, adding sealing sleeves or sealing clamps to the connection parts can enhance the sealing effect through additional pressure, ensure the sealing of copper tube water cooling plates, and provide reliable guarantee for the stable heat dissipation of the equipment.
