Abstract
The utility model relates to a liquid-cooled heat sink which comprises an evaporating unit firmly attached to a heating element, a cooling unit, a first pipe and a second pipe, wherein, the first and the second pipes are communicated with the evaporating unit and the cooling unit. A hollow cavity for storing operating fluid is arranged in the evaporating unit, the cooling unit comprises a cooling chamber, the second pipe is provided with a one-way valve which controls the operating fluid only to flow to the hollow cavity from the cooling chamber in the second pipe, after the operating fluid in the evaporating unit absorbs heat and then evaporates, steam squeezes the operating fluid with high temperature to flow into the cooling chamber along the first pipe; when the operating fluid cooled in the cooling chamber, the operating fluid back flows to the evaporating unit from the second pipe. The utility model does not need to use a pump body so as to save electrical energy as well as to reduce materials and installation cost.
Description
[technical field]
The utility model relates to a kind of heat abstractor, particularly about a kind of liquid-cooling heat radiator that is used for cooling electronic components.
[background technology]
Along with electronic technology constantly develops, electronic component running frequency and speed are also in continuous lifting.But high-frequency high-speed will make the heat of electronic component generation more and more, and temperature is also more and more higher, and performance and stability when serious one-tenth is being coerced the electronic component operation for guaranteeing the normal operation of electronic component energy, need effectively dispel the heat to electronic component.But existing air-cooled heat abstractor more and more is difficult to satisfy the heat radiation needs of high-frequency high-speed electronic component, and for this reason, liquid-cooled radiating system is adopted by industry gradually, and correlation technique please refer to Chinese patent No. 98248834.3, No. 99210734.2.
Be not difficult to find out that with reference to above-mentioned patent existing water-cooling heat radiating system is formed by connecting by the element of a series of dispersion settings, comprise heat absorbing units, heat-sink unit and the pump housing that drives cooling fluid substantially.In these elements, the pump housing need utilize electric energy to drive.For being for the portable computer such as notebook computer, kneetop computer etc. of demand with the travelling performance, it mainly is to provide electric energy by battery, if give the pump housing with battery part power distribution, will sharply reduce the service time of battery, and the mobility of this and portable computer is inconsistent.
[summary of the invention]
The purpose of this utility model is to provide a kind of and need not to use the pump housing to drive cooling fluid, thereby reduces the liquid-cooling heat radiator of power consumption.
The technical solution of the utility model is: a kind of liquid-cooling heat radiator, comprise an evaporation element of being close to heater element, one cooling unit and be communicated with first and second conduit of this evaporation element and this cooling unit, establish the cavity of a storage hydraulic fluid in this evaporation element, this cooling unit comprises a cooling chamber, this second conduit is installed a Control work liquid can only flow to this cavity from this cooling chamber in second conduit unidirectional valve, after the heat absorption of the hydraulic fluid in evaporation element evaporation, the hydraulic fluid of steam extruding high temperature flows into cooling chamber along first conduit, when hydraulic fluid is back to evaporation element from second conduit after the cooling chamber cooling.
Because the circulation of the hydraulic fluid of the utility model liquid-cooling heat radiator is to promote by the steam extruding that hydraulic fluid self evaporation back forms, and therefore need not to use the pump housing that needs power drives, thereby saves electric energy, and reduce material and installation cost.
[description of drawings]
Fig. 1 is the side schematic view of the utility model liquid-cooling heat radiator.
[embodiment]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
See also Fig. 1, the utility model liquid-cooling heat radiator comprises an evaporation element 1, a cooling unit 2 and connects first conduit 3 and second conduit 4 of this evaporation element 1 and cooling unit 2.
This evaporation element 1 is close on the heater element 100, is used to absorb the heat of heater element 100.Establish the chamber of a sealing in this evaporation element 1, store hydraulic fluid in the chamber.The hydraulic fluid utilization is subjected to the characteristics of thermal evaporation to take away the heat of heater element 100.According to the heating situation of heater element, generally require the boiling point of hydraulic fluid to be about 40 ℃ to 60 ℃, acetone for example, its boiling point is about 56 ℃.
The bottom of this cooling unit 2 is higher than the bottom level of this evaporation element 1.This cooling unit 2 comprises a cooling chamber 20 and places the equipment that on this cooling chamber 20 this cooling chamber 20 is cooled off, and uses a radiator 26 and a radiator fan 28 in the present embodiment.Be provided with a hollow bulb in this cooling chamber 20, be used to be installed with hydraulic fluid.When the hydraulic fluid of high temperature entered this cooling chamber 20, radiator 26 and radiator fan 28 can cool to it.
The end that first conduit 3 connects evaporation element 1 inserts in the hydraulic fluid.Second conduit 4 is installed a unidirectional valve 5 in the position of closing on this evaporation element 1, the hydraulic fluid in second conduit 4 can only be flowed to evaporation element 1 by cooling chamber 20, and can not be flowed to cooling chamber 20 by evaporation element 1.
The utility model liquid-cooling heat radiator course of work is as follows:
When heater element 100 adstante febres, hydraulic fluid in the evaporation element 1 absorbs the heat of heater element 100, after being heated to its boiling point, the hydraulic fluid evaporation forms the top that steam is filled in this evaporation element 1, continuous formation along with steam, the air pressure of steam can be pressed into the hydraulic fluid of high temperature in first conduit 3, and enters this cooling chamber 20 along this first conduit 3.Hydraulic fluid because unidirectional valve 5 can avoid evaporating in the unit 1 flows into second conduit 4, and therefore, the hydraulic fluid that is extruded can only enter first conduit 3.
After the hydraulic fluid of high temperature enters cooling chamber 20, cooling cooling under the help of radiator 26 and radiator fan 28, flow back into evaporation element 1 from second conduit 4 then and enter next cool cycles, so constantly circulate, can take away the heat of heater element 100 continuously.Flow back in the process of evaporation element 1 along second conduit 4 at hydraulic fluid, it can be the effect (because cooling chamber 20 is higher than evaporation element 1) that is subjected to single gravity, can capillary structure be set at these second conduit, 4 inwalls on the other hand, so can quicken the reflux course of hydraulic fluid by the suction-operated of capillary structure.
