Description
Technical field
The present invention is about a kind of heat abstractor, the heat abstractor that dispels the heat in especially a kind of thermal source position that is incorporated into various electronic product.
Background technology
At present common existing heat abstractor can run well to guarantee electronic product mainly in order to dispel the heat at various electronic product.For example various electronic products such as light fixture, module backlight, LCD (liquid crystal display), computer are easy to generate high heat in the process of real work; therefore; above-mentioned various electronic product usually can be in conjunction with a heat abstractor; and utilize this heat abstractor to dispel the heat, so that prolong the useful life of this electronic product.
Again, electronic product as types such as computers all must concentrate on several electronic components (for example: motherboard, microprocessor, display card or other associated electrical wafers etc.) in the heat sink of existing heat abstractor, and in this heat sink in conjunction with several radiator fans, so that dispel the heat at these several electronic components.For example, please refer to shown in Fig. 1 and 2, existing heat abstractor 9 roughly comprises a heat sink 91 and several radiator fans, discloses these several radiator fans at this and comprises one first radiator fan 92 and one second radiator fan 93; Wherein this heat sink 91 has an accommodation space 911 and several assembly mouths 912, and this accommodation space 911 can be for being provided with several electronic components 94, and these several assembly mouths 912 are communicated with this accommodation space 911; This first radiator fan 92 and second radiator fan 93 are incorporated into this several assembly mouths 912 respectively.
Above-mentioned existing heat abstractor 9 is when reality is used, can import extraneous air-flow by this first radiator fan 92 and enter this accommodation space 911, make air-flow and this several electronic components 94 carry out heat exchange, the high temperature gas flow that utilizes this second radiator fan 93 will finish heat exchange again detaches this accommodation space 911, reaches the purpose of circulation heat radiation whereby.
Yet this existing heat abstractor 9 still has many shortcomings as described below:
1, the heat radiation portfolio effect is not good: owing to should the extraneous air communication of existing heat abstractor 9 importings cross this first radiator fan 92, be discharged outside to by this second radiator fan 93 again; After this air-flow entered this accommodation space 911 and is positioned at several electronic components 94 arround this first radiator fan 92 and carries out heat exchange, the temperature of this air-flow promptly can raise relatively; Therefore, follow-up again when being positioned at several electronic components 94 arround this second radiator fan 93 and carrying out heat exchange when this high temperature gas flow, will produce problem scenario such as cooling deficiency, cause this existing heat abstractor 9 to have the not good shortcoming of heat radiation portfolio effect.
2, do not have automatic dedusting function: when this existing heat abstractor 9 long-time constantly from this first radiator fan 92 introduce air-flows and the process that is discharged outside to by this second radiator fan 93 in, the dust that the air-flow in extraneous space is carried secretly also constantly is piled up in the ad-hoc location of existing heat abstractor 9 easily, for example: positions such as accommodation space 911, this first radiator fan 92 and second radiator fan, 93 inside; Therefore, the dust that existing heat abstractor 9 uses the back to be piled up between for a long time, quite easy whole intake of influence or air output are so also further cause the radiating effect that has heat abstractor 9 now to reduce.
Summary of the invention
The object of the invention provides a kind of heat abstractor, in order to solve the not good problem of heat radiation portfolio effect of aforementioned existing heat abstractor.
Another goal of the invention of the present invention provides a kind of heat abstractor with automatic dedusting function.
The heat abstractor according to the present invention comprises a heat sink, at least one radiator fan and a rotating control unit.The inner airflow space that forms of this heat sink, this heat sink is provided with several air guide holes that are communicated with this airflow space; This at least one radiator fan has two air dams, wherein the wherein at least one air guide hole in several air guide holes of this heat sink of the corresponding connection of an air dam; This rotating control unit connects this at least one radiator fan, in order to control the running of this at least one radiator fan.
The useful technique effect that heat abstractor of the present invention can reach is: utilize the rotating control unit to control the running of this at least one radiator fan, and cooperate the structural design of this heat sink, promote the heat radiation portfolio effect and have the automatic dedusting function effect to reach, provide comparatively perfect heat sinking function whereby, so can effectively promote the useful life of electronic product.In addition, in addition at least one temperature-sensing element can be set in this heat sink, this at least one temperature-sensing element is electrically connected this rotating control unit.Whereby, can utilize the temperature at each position in this airflow space of the quick sensing of this temperature-sensing element, so that the respectively running of this radiator fan of the visual demand quick control of this rotating control unit, so that more suitable cooling mechanism to be provided.
