The computer used at present depends on greatly cold air and lowers the temperature to machine, but the heart in the data, only by the air-cooled cooling requirements being insufficient for high heat flux server. Liquid is cold, namely utilizes working fluid as the medium of middle heat transmission, is delivered to by hot-zone by heat and cools down at a distance again. Owing to liquid is more much larger than the specific heat of air, radiating rate is also far longer than air, and therefore refrigerating efficiency is far above wind-cooling heat dissipating mode, also can be well controlled in noise simultaneously.
The maximum feature of liquid cooling heat radiation system has two: one to be heat and the low noise work of balanced CPU. Due to the specific heat capacity super large of liquid, therefore, it is possible to absorb substantial amounts of heat and keep temperature significantly to change, the control that in liquid cooling system, the temperature of CPU can obtain, the operation of burst significantly changes all without causing CPU internal temperature moment. Two is owing to the surface area of heat exchanger is very big, it is carried out heat radiation just can play good effect so having only to slow-revving fan, the fan that therefore the cold most collocation rotating speed of liquid is relatively low.

Adopt the liquid cooling heat radiation system of cooling indirectly, computer system is changed little, it is only necessary to former wind-cooling heat dissipating sheet is replaced with liquid-cooling heat radiation sheet (liquid cold head), and refrigerant pipeline is drawn cabinet. In the indirect type of cooling, coolant has himself path, does not directly contact with electronic device, as long as therefore liquid line good airproof performance, coolant is not revealed, and this system is relatively low to the requirement of coolant, and multiple coolant all can realize its function.
But, existing indirect liquid cooling system imperfection, especially for the monitoring aspect of whole system, once there is liquid leakage, during the accident such as pipeline blockage, existing indirect liquid cooling system cannot detect fault in time, thus the safety of server cannot be ensured.

By the such scheme of the present invention, it is possible to by detecting the pressure information of chiller, thus the duty of monitor in real time chiller, it is ensured that the safety of server.
Concrete, in one embodiment of the invention, the cooling system that the present invention relates to is indirect type cooling system, i.e. chiller separates with heater element. Especially, in one embodiment of the invention, chiller is cooling plate type radiator. In one embodiment of the invention, chiller is provided with inlet and liquid outlet, and this chiller contacts with heater element. In one embodiment, heater element can be the CPU of server. In a preferred embodiment, can arranging a Heat Conduction Material between chiller and heater element, this Heat Conduction Material can be heat-conducting silicone grease. The cooling system of the present invention also includes a refrigerating plant, and the two ends of this refrigerating plant connect with the inlet of chiller and liquid outlet respectively.
Concrete, in one embodiment of the invention, the cooling handling process of server heater element is by cooling system: chiller imports cooling liquid by inlet, the heat sent by heater element by being close to the one side of heater element is transferred to cooling liquid, cooling liquid heats up after absorbing heat, boiling, and flows out from liquid outlet. The cooled liquid stream flowed out by liquid outlet enters in refrigerating plant, refrigerating plant received the cooling coolant such as water, the coolant body weight of inflow is newly cooled down by the logical supercooled water of refrigerating plant, and the cooling liquid after cooling is back in chiller by the inlet of chiller, process thus completing the cooling to heater element, and the kind of refrigeration cycle of cooling liquid.

In a preferred embodiment, after the cooling liquid in chiller heats up with heater element heat exchange, the pressure fluctuating in inner in chiller should tend to be steady, and the pressure differential imported and exported goes to zero, i.e. the differing pressure of import/export is only small. If described pressure differential exceeds preset range, then proving that chiller there occurs leakage or pipeline blockage, causes chiller cisco unity malfunction, the alarm device in cooling system will alert. In a preferred embodiment, the cooling liquid in chiller utilizes latent heat of phase change principle can become steam. But, the coolant cognition after evaporation causes the pressure in chiller to raise, but, the boiling point of cooling liquid has close contacting with the pressure in device, if pressure raises, can cause the cooling liquid elevation of boiling point, thus being unfavorable for the cooling of server. Therefore, the force value that pressure-detecting device can detect according to the pressure transducer in chiller, whether the pressure determined under current state in chiller is beyond predetermined threshold, if beyond threshold value, alarm device in cooling system will alert, and cut off the power supply of server immediately, thus preventing chiller overheated and causing that heater element damages.
