[0026] After the cooler 61 and the two shunt tubes 62 supply a sufficient amount of coolant to the inner cavities of the number of condenser tubes 71, the coolant in the inner cavities of the number of condenser tubes 71 will flow through the number of connecting tubes 72 until the inner cavities of the number of condenser tubes 71 and the number of connecting tubes 72 are filled with an appropriate amount of coolant.
