Background technology

As everyone knows, heat dissipation problem is related to the stability of computing machine, all becomes the focus that computer manufacturer pays close attention to all the time, and particularly the notebook computer heat dissipation problem is perplexing each manufacturer always.Though the CPU production technology has reached 0.09 micron, radiator fan reaches more than 7000 commentaries on classics, and the restriction that endless noise and overclocking space are subjected to becomes hard nut to crack, and the focus of problem more and more concentrates on the fan.Because the powerful heat-carrying capacity of liquid itself and can controlledly make heat finish directed transfer, liquid cooling becomes the first-selected type of cooling of high-performance computer gradually.The advantage of liquid cooling is: can utilize that less power consumption reaches the circulating of liquid, work noise is very little, can utilize multiple mode to finish the heat radiation process.The heat load ability of liquid-cooling system is very big, be equivalent to 5 times of air cooling system, so the CPU working temperature is low and stable.

The traditional water cold heat sink generally is made up of submersible pump, storage box, bucket, water pipe etc.After system connected, water pump energising was injected storage box with the bucket inner cold water, and cold water is taken away computing machine heat generating member heat and is back in the bucket in the storage box, and is simple in structure, cost is low.Existing water-cooling heat radiating system improves to some extent on this basis, replaces bucket with water tank, and heating radiator adopts the heat radiation type structure that the heat of hot water in the radiating tube is outwards shed, and utilizes fan to strengthen radiating rate.Total system complex structure, cost are higher relatively, simultaneously bulky, be difficult to have living space in the general computing machine and hold water tank and heating radiator, thereby in application, be subjected to certain limitation, be unfavorable for that computing machine is integrated, particularly notebook computer will be realized the notion challenge of " thinner ", " littler ", " lighter ", and the miniaturization of water-cooling system has been proposed more harsh requirement.

Summary of the invention

The purpose of this utility model provides the cooling device that a kind of liquid-cooled is used for the computing machine heat generating member, to solve the problems referred to above that present computing machine cooling system exists, improves practicality, the reliability of computing machine cooling system.

The cooling device of the utility model computing machine heat generating member, the water tank, water pump, heat interchanger, the heating radiator that connect by pipeline) the closed loop liquid cooling system formed, it is characterized in that described water pump is a Piezoelectric Driving pump, this pump is installed in the water tank, the water delivering orifice of its pump directly is communicated with pipeline by the outlet that is located on the water tank, and its water inlet leads directly in water tank cavity.

The utility model is owing to adopt the Piezoelectric Driving pump as the liquid circulation propulsion system, and integrate with water tank, make the system architecture compactness, reduced the volume of whole cooling system, and heating radiator can arbitrarily be placed, be not subjected to the computer-internal limited space, can be widely used in various computing machines, practical, attractive in appearance generous again.

Embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model cooling device.

Embodiment 1

With reference to Fig. 1,2, the cooling device of the utility model computing machine heat generating member, the closed loop liquid cooling system that water tank 10, water pump, heat interchanger 3, the heating radiator 14 that is connected by pipeline 18 formed, it is characterized in that described water pump is a Piezoelectric Driving pump 9, this pump is installed in the water tank 10, the water delivering orifice 7 of its pump directly is communicated with pipeline 18 by the outlet 6 that is located on the water tank 10, and its water inlet 8 leads directly in water tank 10 inner chambers.11 is the water filling port of water tank 10, and 12 is the inlet of water tank 10.

Piezoelectric Driving pump 9 is formed in the following manner, the two ends that film piezo-electric pottery 25 and substrate 23 are pasted the piezoelectric vibrator of forming are installed on the end walls of the pump housing 24, be connected on film piezo-electric pottery 25 and the substrate 23 being provided with 8, two automatically controlled signal lines 20 of forward and reverse each other conical water outlet 7 and water inlet on the sidewall of the pump housing 24.

Heat interchanger 3 be on a copper billet, directly process heat exchanger channels 1 and enter the mouth 5 and outlet 4 form.

Heating radiator 14 is made up of heat dissipation box 16 and the radiating tube 15 that is welded on the one side, all is covered with convection current hole 21 on other sides of heat dissipation box 16, and the going into of radiating tube 15,
