At present, there are six main types of LED cooling technologies .
1, SynJet replaces the fan
Applied to LED lighting, the general principle of SynJet is that a diaphragm-like component vibrates the air in the compression chamber at a certain frequency. After the air is compressed, it is ejected from a small nozzle at a high speed to form an air bomb to the heat sink. The bomb drives the air around the fins to remove heat. According to reports, the technology was originally used for the heat dissipation of the chip, and after the rise of LED lighting, it was used to replace the huge fan.
Compared to the fan, the SynJet thermal module has the following features:
The power consumption is lower than that of the fan: the main energy-consuming part of the SynJet thermal module is a drive module, and the diaphragm has lower power consumption than the motor part of the fan. According to reports, taking 10WMR16 as an example, after a long time of lighting, the LED soldering temperature is about 50 ° C; 15 W Par 20, about 55-60 ° C.
Small size and light weight: Due to the special structure of the SynJet thermal module, it can be used in a small size and can be used in some downlights where the fan cannot be installed. The small size and good heat dissipation enable large-sized LED lamps to achieve greater power and brightness.
Low noise: The motor of the fan is inevitably generating noise when it is rotating. If it is used for indoor lighting , the noise will be more obvious when it is quiet at night. The diaphragm of the SynJet thermal module vibrates at frequencies that are insensitive to the human ear, with little noise and no noise. According to reports, the SynJet thermal module has three sets of frequency adjustable.
Long life: SynJet cooling module has a simple structure with a life expectancy of 100,000 hours, while fans usually only have 5,000 hours. For long-life LED lamps, 5000 is obviously a bit of a hindrance. When applying the SynJet thermal module, one thing to pay special attention to is that the entire lamp cup should have an opening to ensure that the internal air can be exchanged with the outside world, otherwise the heat dissipation effect of the SynJet will be compromised.
