Benefits of technology

The patent text explains that the construction of heat sinks has been improved to make them more efficient. This is achieved by using serpentine fins or longitudinal grooves to increase the surface area for heat transfer. The results are a reduction in temperature differences of up to 60F for the same operating conditions.

Problems solved by technology

Due to these efficiency issues, thermoelectric cooling devices are typically restricted in use to solid state applications where the benefits of cooling far outweigh the additional energy requirements.

Embodiment Construction

[0018]FIG. 1 shows a heating and / or cooling system 10 of the presently preferred embodiment in the form of a heat pump which could also be an air conditioner, heater or cooler depending on the particular application. Heating and / or cooling system 10 preferably comprises one or more thermoelectric devices also known as Peltier devices 12,14,16,18 which may be electrically connected in series or otherwise and / or may be provided as a single Peltier device having desired dimensions and / or capabilities.

[0019]The prototype built by the applicant 2 utilized devices 12,14,16,18 having dimensions of approximately 1½″×1½″×¼″ connected in series. Thermoelectric devices are not new in the art. In fact, they are believed to have been around for well over twenty years. Patents such as U.S. Pat. No. 6,304,741 show an improvement. U.S. Published Patent Application No. 2009 / 0133409 shows an application. Both of these documents are incorporated by reference. FIG. 1 of Published Patent Application No....

Abstract

A thermoelectric cooling device has first and second sides which can act as hot and cold sides. Heat exchangers are preferably in thermal conductance with the first and second sides and air may be directed by fans past the heat exchangers. Closed fluid systems may also be used. Furthermore, improved heat sink constructions are believed to improve the efficiency of the thermoelectric device.

Description

CLAIM OF PRIORITY[0001]This is a continuation in part of U.S. patent application Ser. No. 13 / 974,434 filed Aug. 23, 2013, which is a divisional application of U.S. patent application Ser. No. 13 / 099,436 filed May 3, 2011 which claims the benefit U.S. Provisional Patent Application No. 61 / 330,691 filed May 3, 2010, all of which are incorporated herein by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to thermoelectric cooling devices, and more particularly to a thermoelectric cooling device(s) having a magnetic field imposed thereon thereby decreasing the amount of current at a particular voltage otherwise needed to provide a desired temperature change.DESCRIPTION OF RELATED ART[0003]Thermoelectric also referred to as Peltier devices have been around for many years. However, as described by Wikipedia, they are typically around five to ten percent as efficient as an ideal refrigerator as compared to twenty to sixty percent which can be achieved by ...
