Abstract: Testing heating and chilling capabilities in a single product is required for the design and fabrication of a portable warm chiller. Instead of using the traditional refrigeration approach, the Peltier effect is used to create cold temperatures. The Peltier effect, a thermoelectric system, is how this operates. The Peltier device, the centrepiece of the project, is made up of a heatsink, which acts as a heat reservoir and dissipates heat from the device into the atmosphere. Heat exchangers include heat sinks as well. This project's significance lies in the creation of a mobile gadget that may be utilized wherever you like. Additionally, if we choose, we can create this item by conserving energy once and utilize it whenever we like in the future.

Keywords: Peltier effect, Refrigeration methods, Heat sink, Heat Exchanger, Thermoelectric Refrigeration.
