Thermally conductive gel is widely used in LED chips, communication equipment, cell phone CPU, memory modules, IGBT and other power modules, power semiconductor field.
The application is in the LED bulb light in the drive power supply. In the export of LED lamps, in order to pass the UL certification, manufacturers more than two-component potting adhesive for potting. Exported to the United States lights are required to 50,000 hours of warranty to the current quality of the LED lamp beads is no problem, the main failure is the power supply, the use of potting adhesive potting after the power supply can not be disassembled, can only be scrapped and replaced the whole lamp. If the use of heat-conducting mud on the power supply for local filling, can effectively export heat, if the power supply has a problem can also be convenient for power supply replacement for the enterprise to save costs. Of course, for the requirement of waterproof lamp. Because the thermal mud can not be like potting adhesive for all and gap filling, can not do waterproof moisture, still need to use potting adhesive.
Another typical application is in the LED fluorescent tube, for the power supply on both ends of the design, in order not to take up too much of the size of the lamp, the power supply at both ends of the space is relatively small, and 1.2 meters LED fluorescent lamp power is usually designed to 18w to 20w, so that the drive power of the heat generation has become relatively large. Heat-conducting clay can be filled into the gap of the power supply, especially attached to the power device to help dissipate heat to extend the life of the lamp. For some sealed module power supply, it can be filled locally with thermal mud to achieve the effect of thermal conductivity.
Next is the chip's heat dissipation, about this way, we should also be more familiar, similar processor and radiator in the middle of the kind of silicone layer is a principle, its role is to allow the processor to emit heat can be faster transfer to the radiator so as to emit out.
Similarly, thermal gel can also be applied in the cell phone processor, in Huawei's cell phone processor will be used similar to the silicone thermal gel heat sink, this is better than only affixed with graphite thermal film contact effect, heat conduction will be more rapid.
