Title:
COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/161992
Kind Code:
A1
Abstract:
A cooling system comprises a refrigerant supply unit (10), a cooling unit (20) used for cooling a to-be-cooled object, a liquid seal groove (30) and a refrigerant recycling unit (40). The cooling unit (20) communicates with the refrigerant supply unit (10) through a refrigerant input pipe (21). The refrigerant recycling unit (40) comprises a refrigerant recycling pipe set (41) and a vacuum pump set (42). The refrigerant recycling pipe set (41) comprises a refrigerant recycling branch pipe (411), a vacuum pipe (412) and a siphon (413), all of which communicate with one another through the same port. The vacuum pump set (42) is connected with the vacuum pipe (412). The refrigerant recycling branch pipe (411) communicates with the cooling unit (20). The siphon (413) communicates with the liquid seal groove (30). The horizontal plane where the refrigerant supply unit (10) is located is higher than the horizontal plane where the liquid seal groove (30) is located. Due to the fact that a certain height difference exists between the refrigerant supply unit (10) and the liquid seal groove (30), cooling water in the refrigerant supply unit (10) can overcome resistance of a pipeline and enters the liquid seal groove (30) by itself. Due to the fact that the whole cooling system is in negative pressure, when the cooling unit is fractured, a refrigerant cannot overflow or hardly overflows, and accordingly production accidents caused by refrigerant overflow can be better reduced.
