TL; DR
- Samsung may not use vapor chamber cooling on the Galaxy S22 series, as previously discussed.
- Phones could settle for thermal graphite pads for heat dissipation.
Samsung apparently wants to cut the costs of heat sink technology for the Galaxy S22 series. According to a new rumor via a tipster FrontTron, the company cannot use vapor chamber cooling on new flagship products.
This isn’t the first time we’ve heard of Samsung considering vapor chamber cooling for the Galaxy S22 series. A previous report also claimed that the technology would improve the efficiency and performance of phones.
Samsung used steam chambers on the Galaxy S10 series. However, the company subsequently abandoned the technology in favor of multi-layered graphite thermal pads as the primary means of removing heat from the processor.
Is Steam Chamber Cooling Really Important?
Back when Samsung launched the Galaxy Note 20 series, it used two types of cooling systems. Some Galaxy Note 20 Ultra used graphite thermal pads while others had a copper vapor chamber for cooling. Many believed that the omission of vapor chamber cooling on some Note 20 Ultra models was the reason the phone felt hot.
However, a survey conducted by people at iFixit found that there was little difference between the heat dissipation performance of vapor chambers and graphite. The post quoted a thermal engineer as saying, “As long as you take the gap tolerances into account, it can be pretty straightforward to swap them out for each other. “
On the cost side, the engineer pointed out that Samsung could use heat pipes and steam chambers for a long time due to the volume of devices sold. When Samsung first used a steam chamber, the company reportedly estimated that it sold up to a million additional phones due to the novelty of having a steam chamber. The decision not to use the technology in newer phones like the Galaxy S21 and perhaps the Galaxy S22 series could be due to the fact that it isn’t as excited as it used to be. It probably won’t change much to performance.
What do you think about Samsung sticking to graphite thermal pads to cool Galaxy S22 phones? Is this really important to you? Take our survey above and drop us a line in the comments section.
