Disclosed is a dual-loop circulation cooling system for an oven of a liquid crystal manufacture process, including a water pump, a water tank, a water drawing pipe, a water returning pipe, and a first cooling pipe and a second cooling pipe. The water pump, the water tank, the water drawing pipe, and the water returning pipe are arranged outside the oven. The first cooling pipe and the second cooling pipe are two juxtaposed cooling pipes that are arranged substantially parallel inside the oven. The water pump drives coolant contained in the water tank through the water drawing pipe into the first cooling pipe and the second cooling pipe inside the oven, whereby the coolant removes heat from the oven and then returns through the water returning pipe back into the water tank. The coolant flows in the first cooling pipe and the second cooling pipe in opposite directions.
