You do not have to worry complicated installation procedure, and without worrying leakage, the water cooling liquid of integrated water-cooling device is when leaving the factory
Filling completion only need to twist the turn of the screw just, greatly reduce the threshold of CPU water-cooling；
Water-cooled radiator 6 is equipped with cold heat exchange water tank, and heat sink 602 is that water flow recycles inside water-cooled radiator 6,
Heat on CPU is taken on water cooling row, is then arranged by water cooling and heat is distributed, the water by cooling flows back on CPU again
Continue to absorb heat, so recycle；
CPU water-cooled radiator refers to that forced circulation takes away the heat of radiator under the drive of pump using liquid, and air-cooled
It is stable, small to condition depended compared to having many advantages, such as peace and quiet, cooling.
The heat dissipation performance of water-cooled radiator is directly proportional to wherein cooling fluid (water or other liquid) flow velocity, the flow velocity of refrigerating fluid
It is again related to refrigeration system pump power.And the thermal capacity of water is big, and this, which allows for water cooling refrigeration system, hot well bear
Loading capability.5 times of air cooling system are equivalent to, caused direct benefit is exactly that CPU operational temperature curve is very gentle.For example, making
Can occur temperature thermal spike in a short time in the biggish program of operation cpu load with the system of air-cooled radiator, or having can
CPU warning temperature can be exceeded, and water-cooling heat radiating system is then since thermal capacity is big, heat fluctuation is relatively much smaller.
With the increase of power equipment power, it is only unable to satisfy the cooling requirement of power equipment by air cooling mode, occurs
Water-cooling heat radiating device, water-cooling heat radiating device mainly include water-cooling head and water-flowing path, and water-cooling head is directly attached on heat generating component
To absorb heat caused by heat generating component, water-flowing path, which is connected to water-cooling head and passes through the heat exchange of working fluid, takes away heat
Amount, achievees the purpose that cooling.
It will be said that electricity is together with water, and it is not danger close, it is in fact this to worry to be extra.Water-cooling is one
Relatively closed cyclic system, the position contacted with heat source are also to be connected by metal, liquid only in water pipe internal flow,
The phenomenon of leakage conductance electricity is not will cause.In addition, the water cooling accessory of modern crafts production, precision is very high, hardly exists
The case where leak, stringent characterization processes also can add one layer of safeguard measure to it again.
The fast development of electric power be unable to do without the efficient operation of power equipment.Water-cooling has very big hair in this field
Space is opened up, will have wider application in future.
Structural principle: the form 202 installed in door component 2, convenient for staff from outside viewing cabinet in situation, two groups
The bottom of shutter 3 and cold-rolled steel sheet cabinet body component 1 are hinged, and top is by hinged with one end of two groups of first connecting rods 303, and two groups
The other end of first connecting rod 303 is hinged with two groups of second connecting rods 304, and the other end of two groups of second connecting rods 304 is hinged on cold rolling
On steel plate cabinet body component 1, shutter 3 can be opened when needed, not need just to close shutter by door lock 302
It closing, the laminate 402 installed between four groups of columns 401 provides mounting platform to electrical component assemblies 5, if be arranged on laminate 402
Dry group ventilation hole 40202 is convenient for air circulation, is conducive to heat dissipation；
Cooling plate component 7 is mounted on the inner tip of cold-rolled steel sheet cabinet body component 1, and heat sink 701 can adsorb a large amount of heat
Amount, radiator fan 702 are accelerating air circulation that heat sink 701 is discharged by the shutter of two sides, and water-cooled radiator 6 is mounted on
The inner bottom of cold-rolled steel sheet cabinet body component 1, not only simple to install, good heat dissipation, it is often more important that very safe, you do not have to worry multiple
Miscellaneous installation procedure, without worry leakage, the filling completion when leaving the factory of the water cooling liquid of integrated water-cooling device is only needed
Stubborn the turn of the screw just, greatly reduces the threshold of CPU water-cooling.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
