A cooling and carbonation apparatus (1) is described which has a cell (2) through which fluid to be cooled and carbonated flows. The cell (2) has first and second sidewalls (9, 15), and an outer wall (13) at least partially enclosing the first sidewall (9) of the cell (2) to form a coolant chamber on a first side of the cell. A cooling device (21), such as a Peltier device, is disposed on one side of the cell (2) in thermal connection with the cell (2), so that heat can be withdrawn from the coolant and the fluid to be cooled in a direction generally across the flow path of the fluid. A body of refrigerated coolant is maintained adjacent to the first sidewall (9) of the cell (2) thereby enhancing the cooling of the fluid. Carbon dioxide can be fed to the cell (2) and the liquid to be cooled pumped out of and back to the cell (2) to improve carbonation.

[ We claim:] [1.] An apparatus for cooling a body of fluid, said apparatus comprising:a cell (2) through which fluid to be cooled may, in use, flow, said cell having a first sidewall (9), a second, opposite sidewall (15) spaced from said first sidewall, an inlet (30) and outlet (28) disposed at opposite ends of the cell to define a flow path for the fluid between the sidewalls in a direction from one end of the cell to the other end of the cell;a coolant chamber adjacent said cell, said coolant chamber being partially defined by an outer wall (13) at least partially enclosing said first sidewall of said cell, said coolant chamber containing a body of coolant; anda cooling device (21) disposed on said second sidewall of said cell, said cooling device withdrawing heat from the fluid in said cell and said body of coolant in said coolant chamber across the flow path of the fluid in the cell to maintain a body of refrigerated coolant in said coolant chamber adjacent said first sidewall of said cell to enhance the cooling of the fluid in said cell.
