Which Peltier Cooler Performs Better: TEC2-19006 or CL-C067?

TL;DR

The TEC2-19006 Peltier cooler achieves better performance, reaching temperatures as low as -32.9°C, while the Hiki Tech CL-C067 only reaches -25°C. This highlights a key trade-off in Peltier coolers: achieving lower temperatures doesn’t necessarily mean better heat removal, as lower cold-side temperatures correlate with decreased cooling capacity.

Transcript

welcome everyone in this video I'm going to test two new patio coolers I haven't tested these type of patio coolers before so it's time to test them and the reason why I want to test these and publish a video about it is because first of all there is a very very little information available about these Apache coolers there is no data sheet there is...

Key Insights

• 😘 The Tec2-19006 cooler effectively achieves lower temperatures, which is essential for specific cooling applications, outperforming other models like the Hiki Tech CL-C067.
• 😘 The trade-off between the lowest achievable cold side temperature and the cooling power is critical; one cannot maximize both simultaneously using a single cooler.
• 😎 The findings illustrate a misconception common among users regarding the relationship between temperature drop and cooling performance in patio coolers.
• 🍃 The video serves as a practical experiment to fill the knowledge gap left by the limited accessibility of reliable data on patio coolers.
• 🔠 The testing methodology involves careful monitoring of electrical inputs and their thermal output, emphasizing an empirical approach to understand performance.
• 🥺 There is a notable challenge in finding accurate specifications online, leading consumers to rely on tests like those presented in this video for informed purchasing decisions.
• 😥 The presenter points out the importance of understanding how internal components interact, such as the effect of Joule heating when too much power is supplied.

Questions & Answers

Q: What is the main focus of the video?

The main focus of the video is to test two patio coolers, Tec2-19006 and Hiki Tech CL-C067, to evaluate their cooling performance and clarify the limited information available about these models. The presenter aims to provide practical insights into their actual temperature capabilities, something that has been scarce online.

Q: What significant performance difference was found between the two coolers?

The significant performance difference found between the two coolers is that the Tec2-19006 achieved a cold side temperature of approximately -32.9 degrees Celsius at maximum power, while the Hiki Tech CL-C067 only managed to reach around -25 degrees Celsius. This indicates that the Tec2 model is significantly more effective at achieving lower temperatures compared to the Hiki Tech model.

Q: How does the presenter explain the concept of heat transfer in relation to cooler temperatures?

The presenter emphasizes that just because a patio cooler can achieve a very cold temperature on the cold side does not mean it can efficiently transfer large amounts of heat. There is a trade-off between achieving low temperatures and the ability to move heat, meaning a lower temperature may result in less effective cooling performance when trying to remove heat from surrounding areas.

Q: What setup was used for testing the patio coolers?

The presenter constructed a test setup using a CPU cooler to provide sufficient cooling for the hot side while ensuring the cold side was sealed. They progressively increased the current in half-ampere increments from 0.5 to 6 amps and monitored the temperatures with thermocouples to collect performance data for analysis.

Summary & Key Takeaways

• The video conducts a detailed performance test of two patio coolers that have limited available information online, aiming to uncover their cooling capacities.

• One cooler, the Tec2-19006, performs well, achieving temperatures as low as -32.9 degrees Celsius, while the Hiki Tech CL-C067 only reaches -25 degrees Celsius.

• Key insights emerge about the trade-off between low temperature and cooling capacity, emphasizing that achieving extremely low temperatures does not necessarily correlate with effective heat removal.
