A substantially planar panel heat exchanger having an elongated liquid storage vessel in the form of a closed loop that is adapted for circulation of liquid. The loop is substantially planar and adapted to be disposed substantially vertically. The elongated storage vessel has a Peltier thermoelectric device located such that one end of the Peltier device is in contact with liquid in the liquid storage vessel and disposed to heat or cool the liquid. The closed loop for the circulation of liquid is comprised of a plurality of vertical tubes formed from a thermoplastic polymer having a diameter in the range of 1.3-6.4 mm and a wall thickness of 0.13-0.76 mm. A first set of tubes is for upward movement of liquid from the Peltier device and a second set of tubes is for downward movement of liquid to the Peltier device. The first and second set of tubes are interconnected to form a closed planar loop and are in fluid flow communication with the end of the Peltier device in contact with liquid in the closed loop. The first and second set of tubes are aligned, linear in cross-section and conform to a planar surface. The circulation loop may contain a pump. The heat exchanger is particularly useful in a portable beverage cooler.
