It crosses recirculated water to take away, finally flows back into cooling-cycle device refluxing opening and cooled down again, the water that closure is consequently formed is recycled back to
Road.Compared with traditional indirect type of cooling, cable is cooled down by the way of soft tube winding, reduces intermediate medium heat dissipation
Link, cooling effect can theoretically be equal with direct cooling mode, and enforcement difficulty is far below direct cooling mode, passes through cooling
The water compulsory circulative cooling means of circulator take away the heat of cable operational process generation, are chronically at operation cable lower
Environment temperature, avoid the excessively high influence service life of cable conductor temperature.
As optimization technique means: cable is equipped with heat insulating device after winding hose, in winding hose periphery.Pass through
Attemperator is set in hose periphery, can be better achieved heat-insulated, can be effectively reduced in external high temperature heat is conducted into.
As optimization technique means: when the described soft tube winding cable, being close to gapless between the adjacent turn circle of hose.
Accomplish that the cooling contact of the maximum of cable is realized and best cools down heat exchange.
As optimization technique means: the attemperator uses non-metallic insulation material.Attemperator cannot contain gold
Belong to material, avoid that circulation can be generated after conductor galvanization, non-metallic insulation material can be and the high molecular material of heat insulation effect, such as
Plastic foam etc..
As optimization technique means: the cooling-cycle device is the SAPMAC method device that can freeze, it can be achieved that system
