Title: COOLING DEVICE OF REDUCING-AGENT INJECTION MODULE AND SELECTIVE CATALYST REDUCTION SYSTEM HAVING SAME
Abstract:
A cooling device of a reducing-agent injection module comprises: coolant circulation lines that are connected to a module cooling channel to cool the reducing-agent injection module and circulate coolant; a closed-loop circulation line connected to the coolant circulation lines on the front and rear sides of the module cooling channel to make the coolant circulation lines selectively form a closed loop; and at least one heat-dissipation part provided at the closed loop to radiate heat transferred from the module cooling channel through natural convection.
