As a result, two-component gel is widely used in automotive electronics, includingelectric drives, electronic controls, battery thermal conduction, 5G communication network equipment, and other fields.What is the input-output ratio of the two-component gel solution?Using the two-component gel scheme for a typical customer’s power battery as an example, the fixed asset investment includes automation dispensing equipment, as well as the time required for equipment debugging and installation. When compared to the traditional manual installation of thermally conductive pads, the amount of gel dispensed using the automated dispensing scheme is less than the weight of the pads, and it eliminates the need for manual labor. Therefore, dispensing up to 10,000 sets of tooling can achieve break-even.How to implement the two-component gel dispensing plan for power batteries?Let’s take the typical example of automated gel application in power batteries, where an automatic dispensing section is added to the automated line. In this setup, the automatic dispensing equipment utilizes 5-gallon or 55-gallon A/B gel barrels. The gel is pressurized using a platen pump and measured with a plunger cylinder. It is then dispensed using a precision dual-liquid gel valve and mixed with a static mixing tube. The fully mixed gel is applied onto the surface of the liquid-cooled plate by a robotic arm. The gel delivery process is fully sealed to ensure that the gel does not come into contact with air during flow. This significantly reduces the occurrence of bubbles and effectively prevents other process problems that may arise when the gel interacts with air.
