Thermoelectric cooling systems

Abstract

The present disclosure provides a thermoelectric cooling system with improved performance. The thermoelectric cooling system comprises a thermoelectric cooling unit. The thermoelectric cooling unit comprises a thermoelectric device, heat pipes, condenser fins, a cold sink and a cold fan. The thermoelectric cooling unit can be easily assembled with a chamber which contains a fluid to be cooled. The thermoelectric cooling system comprises screws to attach the thermoelectric cooling unit to the chamber, and sealant rings to prevent heat leakage in the thermoelectric cooling system. Further, the present disclosure provides a thermoelectric cooling system with a freezer part and a refrigerator part. The freezer part encloses the cold sink and the cold fan. The freezer part is cooled by the thermoelectric device, and the refrigerator part is cooled by walls of the freezer part. Further, the present disclosure provides a thermoelectric cooling system for use as a wine cooler.

Description

BACKGROUND[0001]1. Technical Field of the Invention Disclosure[0002]The present disclosure relates to the field of thermoelectric cooling systems for cooling a fluid. More specifically, the present disclosure relates to compact thermoelectric cooling systems such as thermoelectric refrigerators with optimized positioning of elements.[0003]2. Description of Related Art[0004]The most widely used cooling system is a vapor compression cooling system. The vapor compression system uses chlorofluorocarbon (CFC) refrigerants such as Freon, hydrochloroflourocarbon. (HCFC) refrigerants such as R134, or hydroflourocarbons (HFC) refrigerants such as R410 for cooling. The use of CFC refrigerants in the vapor compression system causes emission of green house gases (GHG), which is an environmental threat. Further, such refrigerants may result in depletion of the ozone layer. Depletion of the ozone layer is an environmental hazard because the ozone layer filters ultraviolet radiation from sunlight....

AI Technical Summary

Benefits of technology

The present disclosure provides thermoelectric cooling systems with optimized positioning and design of elements for achieving a high coefficient of performance and ease of operation. There are various embodiments provided for heat pipes with a cross sectional area and geometry to optimize heat transfer, as well as arrangements and a design for assembling the systems. The technical effects include reducing thermal resistance, improving heat transfer, and ensuring leakage prevention.

Problems solved by technology

Further, when the cross sectional area of the heat pipes increases it results in a larger area for heat transfer, thus lowering thermal resistance inside the heat pipes.
