Embodiment Construction

[0036] refer to figure 1 , which shows a cross-sectional view of a thermoelectric element denoted by reference numeral 10 . Thermoelectric element or device 10 is preferably a solid state device. The device 10 has a first P-type semiconductor 12 and a second N-type semiconductor 14 (with electrons as charge carriers). The current from the power source is passed to the P-type semiconductor 12 through the N-type semiconductor 14 .

[0037] When current is passed as indicated by reference arrow 16 , heat is removed from surface 20 and transferred through thermoelectric device 10 and then stored to second surface 18 of the thermoelectric device as indicated by arrow 22 . The heat removed from the surface 20 causes heat to be absorbed from the adjacent environment by the working fluid in contact with the cold surface 20 . Similarly, heat generated at surface 18 is dissipated through the heat transfer medium. Such thermoelectric devices 10 are well known and understood by those ...

Abstract

A refrigeration system has a compartment and a first cooling device. The first cooling device cools the compartment and generates a magnetic field. The refrigeration system also has a second device. The second device uses the generated magnetic field for additional cooling to the compartment.

Description

technical field [0001] The present invention relates to temperature control of compartments. More specifically, the present invention relates to a magnetic refrigeration system that uses a magnetic field generated by a plurality of thermoelectric elements wound into a configuration. Background technique [0002] Temperature control systems for heating and cooling devices are known in the art. Such known systems use a vapor compression cycle to provide cooling. Typically, refrigerant in the vapor phase is pumped from the evaporator by a compressor. This refrigerant is then compressed into a superheated vapor. High-pressure gas refrigerant absorbing heat is sent to the condenser. The refrigerant vapor condenses to a high-pressure liquid by transferring heat from the refrigerant to a low-temperature radiator. The condensed refrigerant liquid is circulated to the throttle valve. The throttle valve allows the pressure to drop to a lower level and the refrigerant enters the ...
