Energy Transfer Device Portfolio

In this portfolio, I present my design process for creating a thermal energy transfer device, specifically a thermal bottle. To begin, I created a concept web centered around the idea of a thermal energy transfer device. In developing this web, I identified various criteria that my design needed to meet. These criteria included materials, such as insulation quality and durability, along with considerations for cost-effectiveness. Design features like size, shape, and ease of use were also essential. Furthermore, I evaluated performance characteristics, including maximum and minimum temperature retention and ease of cleaning.

Alongside these criteria, I established specific constraints to guide my project, including a budget limit of $30, a completion time of one week, and an emphasis on using locally available materials.

Next, I formulated a design plan for the thermal bottle. The objective was to create a bottle that efficiently retains heat or cold for extended periods. For this, I selected materials, including an outer layer made of stainless steel, vacuum or foam insulation, and a sturdy screw-on cap. The steps for constructing the device included cutting the stainless steel to the desired dimensions of a 500 mL bottle, installing the insulation layer, securely attaching the lid, and testing the seal to prevent leakage.

To visualize my product, I produced a labeled diagram showcasing the device’s components, including the outer layer, insulation layer, and lid. Accompanying the diagram, I wrote a brief description explaining how my thermal bottle functions by utilizing durable materials and effective insulation to minimize heat transfer. The airtight seal prevents heat loss, allowing beverages to maintain their temperature for several hours.

For testing, I set up an experiment to evaluate the thermal retention capabilities of my device. Initially, I measured the temperature of the hot liquid inside the bottle to be 85°C. I recorded temperature data at 30-minute intervals over a five-hour period. The collected data showed a steady decline in temperature: after five hours, the liquid temperature was at 60°C. This demonstrated that my thermal bottle effectively retained heat compared to a conventional bottle, which typically allowed temperatures to drop significantly lower in the same timeframe.

Upon analyzing my data, I concluded that the design was successful in maintaining thermal energy. The thermal bottle's average temperature after five hours indicated that the insulation and sealing mechanisms played a critical role in minimizing heat transfer, effectively showcasing the principles of thermal energy retention.

Reflecting on my findings, I realized that there are areas for improvement in my design. I would consider enhancing the thickness of the insulation layer for better thermal retention, exploring more effective materials for the lid to improve the sealing, and investigating double-walled vacuum structures to further reduce heat transfer.

This comprehensive process highlights my research, design, testing, and conclusions regarding the thermal energy transfer device, illustrating a practical application of thermal energy concepts.
