Background of the Invention
[0004] This invention relates generally to the field of
thermoelectric coolers and more specifically to a Universal
Thermoelectric Module Apparatus. There are different types of
consumer portable coolers on the market today, utilizing a variety
of cooling technology. Some use passive cooling, such as ice
coolers, some use active cooling such as compressor-based coolers
or heat pumps type coolers. A common low-cost heat pump cooler
today often uses thermoelectric technology as the cooling
engine.
[0005] U.S. Pat. No. 5,319,937 to Fritsch discloses a consumer
portable cooler utilizing a thermoelectric heat pump, also commonly
known in this industry as a thermoelectric module. A thermoelectric
module is a heat pump transferring heat from the inside of the
cooler to the surrounding environment. A thermoelectric module
generally consists of a cold side exposed to the inside of the
cooler and a hot side exposed to the surrounding environment. A
thermoelectric chip sandwiched between the cold side and the hot
side provides the active mean of transferring heat from the cold
side to the hot side.
[0006] There are many different commercial embodiments of
thermoelectric coolers on the market today. Each have their own set
of specifications and characteristics. As described in U.S. Pat.
No. 5,319,937 to Fritsch, the invention discloses a thermoelectric
cooler with a unique ventilation system. Such ventilation system is
custom-made for this cooler and is an integral part of the cooler.
Another prior art as described in U.S. Pat. No. 6,073,789 to
Lundblade also discloses a thermoelectric cooler with an integral
thermoelectric module. In the inventions above, the thermoelectric
module is an integral part of the cooler, the thermoelectric module
is specifically designed to fit only this one cooler, repair or
maintenance of the thermoelectric module requires extensive
handling and disassembling.
[0007] Other inventions such as U.S. Pat. No. 5,301,508 to Kahl or
U.S. Pat. No. 6,301,901 B1 to Coffee describe a thermoelectric
cooler using a thermoelectric module where the thermoelectric
module assembly is an integral one-piece engine that can be
installed rapidly without complicated assembly. Such inventions
improves the cooler's assembly process, however, each cooler design
still utilizes a custom-designed thermoelectric module.
Furthermore, such designs require the use of a mounting hardware
between the thermoelectric module and the cooler increasing
assembly labor and compromising good thermal insulation
properties.
