A Mini Fridge that can work with any power bank and without using harmful CFC gases.
Ever heard of a 5V portable freezer? Yes, you heard it right. In this DIY we design a 5V portable freezer that is easy to carry even while traveling.
A freezer/refrigerator/fridge work on the same principle i.e. Pumping heat from one system to another and thermally isolating both the systems so that the pumped heat from one system cools down.
Meanwhile, the other system keeps getting hotter. The system generally acts like a radiator and transfers heat to a sink which is often the environment. Hence the heat transfer from the target system to the environment is done.
The same principle is used to make the 5V portable freezer. The heat is pumped using a thermoelectric generator. This can generate electricity based on the heat difference or it can pump the heat from one side to another side.
While out on picnics or outdoor activities, having a cold drink is what everyone wishes for especially on a hot day, and hence we wish to have some cold storage or a mini fridge. Since these are only found in luxury cars and vanity vans, and apart from being expensive, the CFC gas is quite dangerous to our environment, especially the ozone layer.
This freezer does not use a CFC gas system that causes harm. Also, it is portable and can operate even with less power. It can run on our phone’s power bank and battery. We can attach it to any car or bus to enjoy chilled drinks, ice cream, etc. on ours.
The freezer is portable and can be carried in a travel bag and set against the car dashboard. It works on a 5V-1.5A power source, like a power bank/battery/solar panel.

Designing Mini Fridge
The body of the freezer has to be thermally isolated as much as possible, hence that is designed first. Thermal isolation is much needed since any freezer works on the heat transfer principle, where heat is transferred from one system to another, making a part of the system much colder.
Since the heat is pumped to another system, it makes the temperature of the recipient increase, so if the thermal isolation is not good, heat continues to enter the system and it becomes hard to maintain the temperature inside the freezer.
Here we use the PLA 3D printed design of the freezer case and isolate it with thermal isolating material like Polystyrene/thermal isolator spray and paint. For the body of the freezer, one side of the box is kept open while the other 3 are closed. The open side is for inserting the heatsink and thermoelectric cooler module.

Mini Refrigerator Circuit Connections
The components are connected according to the circuit diagram. The red wire is connected as a +ve wire of the thermoelectric cooler and fan with a 12V power source (battery). The -ve wire is connected with the -ve terminal of the battery and to the -ve wire of the thermoelectric cooler and 12V fan.
The next step is to fix the 3D printed parts and cover the edges with thermal insulator spray foam. Then the door of the freezer is added. A same-size transparent acrylic sheet is cut out and then fixed, such that using a magnetic-based lock system, we can use the door for opening and closing. Magnets are also fixed, on the door and fridge on the body as in Fig 6.

The heatsink and fan are fixed, after which the thermal paste is added and sandwiched between the thermoelectric cooler module and the heatsinks. The fan is added next to the top of the big heat sink fan as in shown in the figures below. (Refer Fig. 7, 8, 9, 10, 11, 12).
Fig 7Fig 8.The thermal paste on a heat sink Fig 9. Thermoelectric fixed and sandwiched between the heatsinkFig 10. Fan added to heatsink fin
Now the heatsink fan is fixed on the top of the refrigerator while inserting the smaller heat sink inside the refrigerator case. Warm the cut part of the refrigerator body and keep the fan exposed on the other side of the refrigerator. (Refer Fig 13,14,15,16).
Fig 11. The fin fixed on the top part of the refrigerator bodyFig 12. The small heatsink fin fixed inside the refrigerator bodyFig 13. Fan exposed to openFig 14. Refrigerator ready after fixing components.
Now power the freezer, which means the fan and thermoelectric cooler will now wait for a few minutes. The heat is now transferred from the inside of the freezer to the outside, making the inside cooler. After 15 minutes the freezer temperature goes down to around 0 degrees Centigrade, making it ready to use.
Your portable freezer is now ready to use and chilled water, ice, beer, and cool drinks can be stored. It can also be carried around anywhere you go, be it for picnics, outings, hiking or can be fixed in the car.
This reference design not only fulfills a variety of functional requirements but also underscores the adaptability and efficiency of using advanced MOSFET technology in conjunction with a dedicated controller for automotive power systems.
The reference design TND6290/D by onesemi provides a detailed, functional example of how the NCV881930 controller can be effectively utilized in developing a high-performance automotive pre-regulator. The design is not only a testament to the capabilities of the controller but also serves as a reliable blueprint for designers looking to implement a similar solution in their automotive systems. T
This reference design of a 100 W non-isolated synchronous buck automotive pre-regulator is built using the NCV881930 synchronous buck controller, complemented by four NVMFS5C460NL 40 V N-channel MOSFETs, to deliver robust and efficient power management suitable for a wide range of automotive applications. These features include integrated compensation which simplifies circuit complexity, a low quiescent current that enhances battery life, and a continuous synchronous mode for better efficiency under varying load conditions. The controller supports a wide input range from 6.0 V to 16.0 V, effectively managing peaks up to 40 V, which is critical for handling automotive voltage fluctuations.
The design operates at a 410 kHz switching frequency, optimizing it for maximum efficiency without sacrificing performance. The choice of the NVMFS5C460NL MOSFETs complements the controller by supporting the high-frequency operation and ensuring reliable handling of high current loads. This combination not only maximizes efficiency but also minimizes the PCB size, as evidenced by the small form factor four-layer PCB used in this design.It is designed to operate with an input voltage range of 6 V to 16 V DC, capable of handling peak voltages up to 40 V. It features a synchronous buck output power topology with a capacity of up to 100 W. The output voltage is regulated at 5.0 V, providing a nominal current of 15.0 A and can handle peak currents up to 20.0 A. This design makes it a versatile and robust solution for automotive power regulation needs.
Overcurrent protection safeguards the device against excessive currents that could damage the circuitry. An external synchronization feature allows the regulator’s operation to be synchronized with other components in the system, reducing electromagnetic interference. The adaptive non-overlap drivers help minimize switch cross-conduction losses, while the integrated spread-spectrum capability reduces EMI emissions. Furthermore, the under-voltage lockout feature ensures the regulator operates within safe voltage levels, protecting both the circuit and the connected load.
This design is intended as a plug-and-play solution for power supply designers, allowing for easy adoption with minimal modifications required to suit specific system needs. The versatile nature of the design makes it suitable for a broad spectrum of automotive applications, from basic power supply roles to more complex electronic system integrations.
