The present invention has following characteristics:
1, the integrated design of heat-collecting devcie and pump:
An important difficult problem of liquid cooling heat radiator is when improving radiating efficiency, takes into account the little and installation, easy to use of volume.What at present general liquid cooling heat radiator adopted is 3 stops or four-part form design, and promptly (1) has the liquid cooling head of heat absorption function; (2) be used to produce the pump of flow of fluid; (3) device that heat is left; (4) water tank; This scheme inevitable requirement entire radiator must be installed three or four devices respectively, thereby has increased the difficulty of installing and using greatly, and has reduced the reliability and the efficient of system.
The present invention has adopted integrated design, and it has following function: (1) high efficiency heat absorbing property; (2) storage of cooling liquid and heat exchange; (3) drive liquid circulation.In fact be exactly that liquid cooling head, pump and water tank (forming water cavity 9 by the pump cover 5 and the pump housing 2) in 3 stops or the four-part form design are combined into one cleverly, installation is both convenient like this, operation is also reliable.
2, the miniature heat-collecting pump structural design that has efficient heat absorption:
The present invention is made up of following structure: (1) pump housing: made by high heat conductive metal material (as copper, aluminium etc.).It has following function: a) outer side surface of pump housing bottom and thermal source closely full contact effectively draw the heat of thermal source; B) inner side surface of pump housing bottom is that heat radiation is stuck up, and can promptly heat fully be passed to cooling liquid; C) but the pump housing and pump cover are formed a certain amount of cooling liquid of water tank splendid attire of a sealing; D) intake pipe, the outlet pipe of cooling liquid are housed on the pump housing.(2) pump cover: make by the little solid material of thermal distortion (as metal or nonmetal).It has following function: a) motor just is installed on the pump cover; B) pump cover and the pump housing are formed the water tank splendid attire cooling liquid of a sealing.(3) motor: can adopt miniature permanent-magnet brushless DC electric machine, volume is little, efficient is high, is the strong impetus source of miniature heat-collecting pump; It is installed on the pump cover, has impeller on the rotor; High speed rotating by impeller, a) will make the cryogenic liquid that enters in pump fast rotational thereupon, and fully contact with the inner side surface of pump housing bottom and to become high temperature coolant after absorbing heat to greatest extent, guaranteed like this that heat is transmitted in the thermal-arrest process efficient and evenly; B) by the centrifugal force that fast rotational produced of cooling liquid, the high temperature coolant behind the absorption heat is pressed into water outlet, enters circulating line.
In sum, the miniature heat-collecting pump among the present invention has following function: (1) can be efficiently with the heat transferred cooling liquid of heater; (2) can drive cooling liquid quick flowing in system forcefully and carry out heat exchange.Just because of this design of miniature heat-collecting pump, just make the radiation system of using this miniature heat-collecting pump only comprise two devices: heat-collecting devcie and sink.Thereby not only make the easy to install and use, reliable of entire heat dissipation system, and the more important thing is the efficient that has improved heat exchange significantly.
3, the design that enters by bottom position by pump housing side of intake pipe:
This miniature heat-collecting pump is in order to improve the efficient of heat exchange, the design of having adopted intake pipe (cryogenic liquid) to be entered by the bottom by pump housing side.This miniature heat-collecting pump is the heat that directly absorbs thermal source by pump housing bottom, if the design of adopting the habitual intake pipe of other liquid cooling heat radiation systems to enter, thereby must make the lower cooling liquid of temperature can not fully contact the heat that can not fully absorb thermal source with the bottom by the top.Therefore in order to improve the heat absorption efficiency of radiator, the present invention has designed intake pipe and has entered by bottom position at the pump housing, guaranteed that fully the low cooling liquid very first time of temperature directly and bottom the pump housing fully contacts, thereby reduced the link of heat exchange, improved the efficient of heat exchange effectively.
4, the inner side surface of pump housing bottom is provided with to dispel the heat and sticks up:
In conjunction with the integrated design of the thermal-arrest and the kinetic pump of this miniature heat-collecting pump, in order to increase heat exchange area, to improve heat absorption efficiency, adopted the heat radiation that (as Fig. 2) or parabolic are stuck up in the heat radiation of concentric circle type to stick up the design of (as Fig. 3) to the base inner surface of pump.Its design feature: (1) is processed into the heat radiation that the cross section is the peak shape in base inner surface and is stuck up, and can make heat exchange area increase 3-4 doubly like this; (2), the heat radiation of peak shape stuck up make concentric circle or parabolic shape in the bottom for the flow direction that heat radiation is stuck up with cooling liquid is matched.This design has guaranteed the disturbance of big as far as possible cooling surface area and as far as possible little flow of fluid, has so not only improved the thermal-arrest ability but also has reduced the consumption of electric energy.
5, the design of blade:
Blade of the present invention is the dipping type blade, and relative upper end, the lower end of blade is along main flow direction inclination 3-5 degree (see figure 1).Intake pipe of the present invention is entered by the bottom by pump housing side, and base wall middle part tangent direction is leaned in the outlet pipe design in pump housing side.The low cooling liquid of temperature enters from the inboard central authorities of pump housing bottom, under the centrifugal action that produces when blade rotation, sticks up to the pump housing is peripheral along the annular heat radiation and to move, and cooling liquid absorbs heat and constantly heats up in the process that moves.The lifting force that relies on the dipping type blade to be produced simultaneously, impel the higher cooling liquid of pump bottom temp to enter the outlet pipe at water cavity 9 middle parts as early as possible, thereby avoid the high cooling liquid of temperature to be trapped in for a long time in the groove that bottom heat radiation sticks up, accelerate thermal cycle and improved the efficiency of cycle.
