Patent ID: 7866164

Claim:
A cooling and heating system, comprising: a heat exchanger including a first section having a first passageway, including a second section having a second passageway, and including a plate, the first and second passageways being separated by the plate, the plate having an aperture therethrough and the first passageway being in fluid communication with the second passageway via the aperature, the first section having a first side facing the second section and having a second side facing away from the second section, and the second section having a first side facing the first section and having a second side facing away from the first section; a thermoelectric cooler coupled to the second side of the first section of the heat exchanger and which is selectively operable to cool or heat a fluid within the first section of the heat exchanger; a thermoelectric cooler coupled to the second side of the second section of the heat exchanger and which is selectively operable to cool or heat a fluid within the second section of the heat exchanger, wherein it is possible to simultaneously cool or heat fluid in both the first and second sections; a heat transfer device thermally coupled to the first mentioned thermoelectric cooler; a fan adjacent the heat transfer device and which is selectively operable to force air relative to the heat transfer device, wherein the fan affects cooling or heating of the fluid within the first section of the heat exchanger; an input conduit coupled between the heat exchanger and the heat transfer device; a return conduit coupled between the heat exchanger and the heat transfer device; and a pump which is selectively operable to circulate the fluid through the input conduit, the heat exchanger, the return conduit, and the heat transfer device; wherein thermal energy existing within the fluid while flowing through the heat transfer device is utilized to heat or cool an environment adjacent the heat transfer device.
