The present invention relates cooling system comprising at least one Thermo syphon, which Thermo syphon comprises at least one indoor evaporator, which is by first tubing connected to at least one outdoor condenser. It is the object of the present application to achieve effective automatic cooling of electronic systems placed inside a housing. This can be achieved by a system as disclosed in that the second tubing comprises a valve, which valve comprises a valve seat and a moveable valve piston, which valve piston is by decreasing temperature by the actuator moving towards the valve seat for closing the valve. Hereby a highly efficient cooling system can be achieved which can operate automatically without any energy supply from the outside, due to the use of the Thermo syphon principle. In situations where the outdoor temperature is decreasing to a low level which could occur in situations where the outdoor condensers in winter periods is cooled to a low temperature, there is a valve, which reduces or stops condensate and liquid refrigerant backwards to the evaporator. |
