Cooling system for a reflow furnace

A cooling system for regulating a temperature of a heating zone of a reflow furnace, wherein the cooling system comprises:

• a blowing apparatus;
• at least one gas inlet and at least one gas discharge port, the at least one gas inlet and the at least one gas discharge port being configured to be disposed on the heating zone;
• at least one gas intake pipeline, an inlet of the at least one gas intake pipeline being connected to the blowing apparatus, an outlet of the at least one gas intake pipeline being connected to the at least one gas inlet, the at least one gas intake pipeline being able to controllably establish fluid communication between the blowing apparatus and the at least one gas inlet;
• at least one gas discharge pipeline, an inlet of the at least one gas discharge pipeline being connected to the at least one gas discharge port, an outlet of the at least one gas discharge pipeline being connected to an outside of the reflow furnace, and the at least one gas discharge pipeline being able to controllably establish fluid communication between the at least one gas discharge port and the outside of the reflow furnace, wherein the heating zone comprises a colder zone and a hotter zone, the at least one gas inlet being disposed at the hotter zone, and the at least one gas discharge port being disposed at the colder zone, wherein the colder zone does not include a gas intake port;
• and
• a control apparatus configured to control the blowing apparatus, control at least one gas intake valve apparatus of the gas intake pipeline, and control at least one gas discharge valve apparatus, wherein the control apparatus is configured to control the gas intake valve apparatus to intake gas to the hotter zone via the at least one intake port and to control the gas discharge apparatus to discharge gas from the colder zone via the at least one gas discharge port.
