<p>PURPOSE:To reduce in size an electronic device and to easily mount the device and facilitate an additional work by providing a flowrate regulator for regulating the flow rate of a whole system by regulating the number of the systems in which liquid refrigerant passes by opening or closing a switching valve, and opening or closing the systems to supply the flow rate responsive to the variation in the construction of the device. CONSTITUTION:In the case that an electronic device 2 is basically composed only of units 11, switching valves 9 of two systems of three systems of flowrate regulators 7 are closed, and refrigerant flows through a constant flowrate valve 10 of only one system. Then, if a unit 12 is additionally provided, the valve 9 of the regulator 7 of another system is opened to supply double flow rate of the refrigerant. If the device 2 is composed of the maximum construction of the units 11, 12, 13, all the valves 9 of the regulators 7 are set to be opened to supply triple flow rate of the refrigerant to the device. The regulators 7 are provided in a cooler 1 thereby to eliminate the necessity of a flowrate regulating work to operate the valves while observing flowrate meters. A refrigerant pipe between the device and the cooler 1 becomes one system to obviate the additional piping at the time of additionally providing units of the device, thereby facilitating an installing work and an additional installation.</p> |
