Preferably, the water system provides the totally-enclosed water cyclic system of heat exchange water flow to give the cooling machine system
System.
The utility model additionally provides a kind of cooler comprising the water circulation protection system.
Cooler provided by the utility model with the water circulation protection system, it is cold when lathe, which supplies water, to be cut off
But machine water route hydraulic pressure increases, the hydraulic controller of water by-pass system by it is normally closed switch to it is normally opened so that cooler forms new water
Road circulation, to avoid triggering water flow switch protection.When lathe needs to restore for cold water, cooling water channel is opened, so that cold
But the hydraulic pressure of machine hydraulic controller one end is reduced, and hydraulic controller switchs to normally closed.I.e. the hydraulic controller is in cooler and lathe
It is in normally off when waterway circulating is normally-open, ensure that effective refrigeration of cooler is all transported to lathe, it will not be to cold
But the efficiency of machine impacts.When cooler and lathe water circulation disconnect, the switch of hydraulic controller is automatically opened, is maintained cold
But machine water route normal circulation avoids cooler from water route choked flow protection occur and shut down, ensure that the even running of cooling machine system.
