Vorrichtung und Verfahren zum Steuern des Öffnen und Schliessen eines Flüssigkeitskanals.

摘要

An apparatus for controlling the opening and closing of a channel for a liquid is arranged such that a liquid channel (4) is closed by causing a controller (6) to control one heat absorbing and generating part of a cooling/heating element (1) to execute heat absorption and cooling a heat transmitting element (2) to solidify the liquid in the channel (4). The apparatus is also arranged such that the channel (4) is opened first by causing the controller (6) to control the same heat absorbing and generating part to execute heat generation and heating the heat transmitting element (2) to melt the liquid solidified in the channel (4). A method of controlling the opening and closing of a channel (4) according to the invention includes the steps of: solidifying a liquid in a channel (4) by cooling it from the outside to close the channel (4); and opening the channel (4) thus closed by melting the liquid solidified in the channel (4) by the application of heat.
