9 best peltier thermoelectric coolers
Peltier thermoelectric coolers, also known as Peltier modules or thermoelectric modules, are electronic devices used for cooling or heating applications. These devices are based on the Peltier effect, which is the phenomenon where an electric current flows through a junction of two different conductive materials, creating a temperature difference across the junction. Here's what you need to know about Peltier thermoelectric coolers:
Principle of Operation: Peltier coolers operate on the principle of the Peltier effect. When an electric current is applied to the thermoelectric module, it causes heat to be absorbed from one side of the module (the cold side) and released on the other side (the hot side). This enables precise temperature control for cooling or heating purposes.
Construction: A typical Peltier module consists of two ceramic plates with semiconductor materials (usually bismuth telluride) sandwiched between them. Metal conductors are attached to the semiconductor elements to allow for electrical connections.
Cooling and Heating Applications: Peltier coolers are commonly used in a variety of applications, including:
Computer Cooling: Peltier coolers can be integrated into computer CPU cooling systems to help dissipate heat and maintain lower operating temperatures.
Electronic Enclosures: They are used to regulate temperatures inside electronic enclosures, preventing overheating of sensitive components.
Thermal Cycling: Peltier modules are employed in laboratory equipment for rapid thermal cycling, such as PCR machines used in genetic research.
Beverage Chillers: Some portable beverage chillers and mini-fridges use Peltier coolers to maintain low temperatures.
Medical Devices: They can be found in medical devices like laser systems, where precise temperature control is critical.
Efficiency and Limitations: Peltier coolers are efficient for small-scale cooling applications but may not be as energy-efficient as traditional refrigeration systems for larger cooling tasks. They can produce significant heat on the hot side, which needs to be managed effectively.
Voltage and Current Requirements: Peltier modules require a direct current (DC) power source to operate. The cooling or heating effect is directly proportional to the current passing through them. Proper voltage and current control are essential to prevent overheating or freezing.
Thermal Management: To maximize the performance of Peltier coolers, effective thermal management is crucial. This includes the use of heatsinks and fans to dissipate heat from the hot side and to enhance the cooling efficiency.
Temperature Control: Peltier coolers can be controlled using electronic temperature controllers that adjust the current passing through the module to maintain a specific temperature.
Size and Form Factors: Peltier modules come in various sizes and configurations, making them adaptable to a wide range of applications.
In summary, Peltier thermoelectric coolers are versatile devices used for cooling and heating applications, particularly in situations where precise temperature control is required. They find applications in electronics, computers, laboratory equipment, and more. Proper thermal management and electrical control are essential for their effective operation.

User questions & answers
| Question: | Can this unit run on solar power |
| Answer: | Grey |
| Question: | how cold does it get at max and min setting |
| Answer: | My cooler is white in the inside |
| Question: | How can i control the temperature using a walford 240w 4-chip semiconductor refrigeration thermoelectric cooler peltier cooling plate with 4 fans |
| Answer: | No wheels |
| Question: | What are the dimensions |
| Answer: | I dont know that answer, all I can say it that when I received it......ALL THE GLASS WAS BROKEN and they would not refund or exchange the product. |
| Question: | does this prevent ice from melting |
| Answer: | Approximately 50. Strangely, there is a can dispenser in the door but the Coors Light cans don’t fit. All in all, we still like the refrigerator. |
| Question: | How much does it weigh |
| Answer: | Mine had a small freezer (shelf) and only 2 non adjustable shelves. Also, I ordered Coors Light but received Miller Light. |
| Question: | Is the lid insulated |
| Answer: | The depth/width of the CL90 Fridge is 18.4" (includes bottle opener) |
| Question: | Does it have a thermostat |
| Answer: | It was not an issue when we went 6,750 across country. |
| Question: | What are the internal dimensions? I have a regular cooler and I can fit 6 large fountains drinks inside including a couple of cold packs |
| Answer: | I would think so. It is their brand for their coolers. It doesn't say that it's for one specific cooler. |
| Question: | do you have open the windows |
| Answer: | I would say "yes", Sandra; 110VAC to 12VDC/5A is standard for portable coolers. Mine works great, I use it everyday! (on the convertor in my office) It actually cools better on the AC adapter than when I've used it of the 12VDC from the car. Hope this helps! :) |
| Question: | wiill this work ine my tent---no electric available |
| Answer: | 60 amps |
| Question: | how long is the power cord that you use in the car |
