Dual Mode 12V Semiconductor Cooling and Heating Device DIY Thermoelectric Cup with Digital Thermostat
Hero Section: Master the Temperature on Your Desk
Imagine having the power to freeze or boil at the touch of a button, right next to your laptop. This isn't just a gadget; it is a "Dreamy Intelligent Machine" that harnesses the Peltier effect to manipulate thermodynamics. Whether you are a maker fascinated by energy conversion or simply someone who hates when their coffee goes cold (or their soda gets warm), this Semiconductor Cooling & Heating Device is your ultimate desktop companion. It’s exquisite, transparent, and undeniably cool—literally and figuratively.
Why Choose This Intelligent Device?
- Dual-Mode Magic (Fire & Ice): Why settle for just a cooler? With a simple mode switch, this device transforms from a refrigerator (dropping to 2-8°C) to a heater (rising to 50-70°C). It’s the perfect all-season tool for keeping your beverages at the perfect temperature.
- Laboratory-Grade Precision: Forget vague "high/low" settings. This unit features a digital thermostat with a measurement and control accuracy of 0.1 degrees Celsius. You can monitor the temperature changes in real-time, giving you total control over the environment.
- Visual Engineering: Built with high-quality transparent acrylic, the internal workings are visible. You can see the semiconductor module, the heatsink, and the fan working in harmony. It’s a conversation starter that looks like a piece of modern art.
- The Perfect STEM Gift: For students and curious minds, this is a hands-on lesson in physics. It vividly demonstrates how electrical energy converts into thermal energy (and how heat is moved), making it a favorite among science teachers and tech enthusiasts.
Technical Highlights: The Science Inside
- The Peltier Effect: At its heart is a thermoelectric semiconductor module. When current flows through it, heat is absorbed from one side and released on the other. By reversing the polarity, we reverse the heat flow, allowing for instant switching between heating and cooling.
- Intelligent Control Logic: The onboard microcontroller monitors the temperature via a sensor. In Cooling Mode (C), it actively regulates power to reach your set point. In Heating Mode (H), it ensures the device stays within the safe 50-70°C range.
- Efficient 12V Operation: Despite its capabilities, it runs on a standard 12V DC power source, making it safe and energy-efficient for desktop use.

Usage Scenario
It’s a hot summer afternoon. You pour a drink into the metal container, set the device to "Cool," and watch the temperature reading drop rapidly. Condensation forms on the cup—refreshment is ready. Fast forward to a winter morning: you switch the wires, set it to "Heat," and your morning tea stays piping hot while you work. It’s practical science that improves your daily life.
Important Tips
- Power Supply Required: This unit requires a 12V DC power supply (not included). Please ensure you have a compatible adapter or battery pack ready.
- Wiring Guide: Connect Red to V+ and Black to COM for standard operation. Follow the included instructions for mode switching.
