10. server level described in any of the above-described claim cools down the control method of heat pipe radiating system, it is characterised in that institute
State server level cooling heat pipe radiating system include natural cooling control model, mechanical refrigeration control model and natural cooling with
Mechanical refrigeration mixes control model, wherein,
When natural cooling source is sufficient, secondary heat pipe heat absorbing end is connected only with secondary heat pipe natural cooling release end of heat, is started certainly
Right cooling control model, now, the import of the three-way valve I is switched to and connected with its first outlet and its second outlet is cut
Disconnected, the outlet of the three-way valve II is cut off with its first inlet communication and its second import, and the first of the three-way valve I
Export and turned on the import of the secondary heat pipe natural cooling release end of heat, the first import of the three-way valve II with described two grades
The outlet conducting of heat pipe natural cooling release end of heat；
When natural cooling source is inadequate, the secondary heat pipe heat absorbing end simultaneously with the secondary heat pipe natural cooling release end of heat, two
Level heat pipe mechanical refrigeration handset group is connected, and is started natural cooling and is mixed control model with mechanical refrigeration, now, the three-way valve
I import connect with its first outlet, second outlet simultaneously, the outlet of the three-way valve II and meanwhile with its first import, the
Two inlet communications, first outlet, the second outlet of the three-way valve I respectively with the secondary heat pipe natural cooling release end of heat
Import, the import of secondary heat pipe mechanical refrigeration handset group conducting, the first import, second import of the three-way valve II respectively with
The outlet of the secondary heat pipe natural cooling release end of heat, the outlet conducting of secondary heat pipe mechanical refrigeration handset group；
When natural cooling source can not be used, start mechanical refrigeration control pattern, the secondary heat pipe heat absorbing end only with described two grades
Heat pipe mechanical refrigeration handset group is connected, now, the import of the three-way valve I switch to disconnected with its first outlet and its
Two outlets, the outlet of the three-way valve II disconnects and its second inlet communication with its first import, the three-way valve
The import of I second outlet and the secondary heat pipe mechanical refrigeration handset group is turned on, the second entrance of the three-way valve II with
The outlet conducting of the secondary heat pipe mechanical refrigeration handset group.
