APARATO DE ENFRIAMIENTO RAPIDO PARA ENFRIAR RAPIDAMENTE UNACORRIENTE DE AGUA.

摘要

For chilling a flow of water a chilling apparatus is provided comprising a water tank in which is disposed the evaporator tube of a refrigerating unit. The tube is in the form of a helix so that water freezes on the tube and bridges the spaces between adjacent coils to form a tube of ice. Water is directed through this tube from the inlet of the tank and the chilled water emerging from the other end of the ice tube is tapped off for use. The cooling efficiency can be improved by placing a helically formed guide element or a series of helically inclined vanes within the evaporating tube helix to guide the water in a helical path. A sensor is conveniently provided within the tube of ice to switch the refigerating unit on when the sensor detects a rise in temperature resulting from melting of the ice tube and to switch the unit off when the sensor is contacted by the ice growing in the tube.
