Claims

[Scope of utility model registration request]

a plurality of electronic modules having electronic components inside; a thin cooling plate placed in contact with the electronic module and having a flow path for cooling liquid therein; and a supply supplying the cooling liquid to the cooling plate. a collection pipe for collecting the cooling liquid from the cooling plate;
Two valves are provided in the supply pipe and the recovery pipe, respectively, to open and close the flow paths of the supply pipe and the recovery pipe, and one end is connected to the coolant flow path between the two valves including the cooling plate. , a water chamber whose other end is open to the atmosphere; a piston that divides the water chamber into a coolant flow path side and an atmosphere side; and a piston that moves the piston to distribute the water chamber between the flow path side and the atmosphere side. 1. An electronic device comprising: a mechanism that can change and fix the pressure; and a pressure gauge that is installed at an arbitrary position on the flow path between the two valves and measures the pressure in the flow path.
