For technical matters, technical scheme and advantage that embodiments of the invention will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The heat that embodiments of the invention produce when moving for chipset heat generating components such as only considering CPU in the prior art, incomplete to the radiating control of machine system, may cause the part high temperature to occur, impact is used; And the heating radiator of computing machine (such as above-mentioned fins group) temperature is not control at present, and for the user, the excess Temperature of the air outlet of heating radiator also can affect the problem of user's use, and a kind of computer heat radiating device combination and control method thereof are provided.
As shown in Figure 2, embodiments of the invention computer heat radiating device combination 20 comprises:
This embodiment compares with the reference value that prestores by the radiating efficiency of 24 pairs of heating radiators 21 of control module; when if the radiating efficiency of heating radiator 21 is lower than the reference value certain value; will point out on the heating radiator 21 dust or foreign material to clear up or carry out corresponding control measure to the user, prevent after long-term the use because the radiating efficiency of heating radiator reduces the overheating protection that brings and obliterated data.
As shown in Figure 3, on the basis of above-described embodiment, the sensor 23 can comprise:
Described control module 24 comprises:
The first control module 241, be connected with described first sensor 231, be used for poor according to described the first temperature and described the second temperature, and the time interval between described first moment and described second moment, obtain the rate of change of temperature within the described time interval of described heating radiator, and rate of change and the described reference value of described heating radiator compared, produce a comparison information; When described comparison information represents to process accordingly when dust on the described heating radiator need to be cleared up, as when as described in comparison information represent as described in dust on the heating radiator produce warning message need to clear up the time, perhaps when described comparison information represents that dust on the described heating radiator need to be cleared up, 21 vibrations of control heating radiator so that dust drop etc.
The time interval between this first moment and second moment can be a Preset Time section in computer starting stage, also can be a constant time period of running status default in the computer operation process.
Among this embodiment, can the prestore reference value of these heating radiator 21 radiating efficiencys of the first control module 241, this reference value is the design phase at computing machine, choose sometime section or the computer starting process time section of the computer run of artificial setting, the radiator fan of computing machine is opened with maximum (top) speed, radiator temperature changes before and after reading this time period, calculates this time period temperature variation with respect to the ratio of the time period benchmark radiating efficiency as heating radiator.Afterwards, in the start-up course of computing machine, read the temperature value of first sensor 231 on the heating radiator 21, and calculate this heating radiator 21 at the radiating efficiency of this start-up course, when if the radiating efficiency of this start-up course is lower than benchmark radiating efficiency value the first preset value, then illustrate on the heat radiator of this heating radiator and piled up more tiny foreign material or dust, then the first control module 24 can produce an information, prompting user carries out cleaning work to the heat radiator of the heating radiator 21 of computing machine, guarantee the heat-sinking capability of the heat abstractor of computing machine, avoid computing machine because of the heat-sinking capability decline of its heat abstractor computer overheating to be shut down; And prevent that obliterated data prevents that local temperature is too high because radiating efficiency reduces the overheating protection that brings after long-term the use, improve user's comfort.
As shown in Figure 4, on above-mentioned Fig. 2 or basis embodiment illustrated in fig. 3, the sensor 23 also can comprise:
The second sensor 232 is for the temperature of obtaining computing machine environment of living in;

Formula according to ideal gas: PV=nRT, wherein, P represents that pressure, V represent that gas volume, n represent that amount of substance, T represent that absolute temperature, R represent gas law constant.All gas R value is all identical, and following consideration is arranged:
The working environment of computing machine can be thought a place that air pressure is constant, that is to say, the air intake of the heating radiator of heat abstractor is identical with the ambient pressure of air-out.Gas volume by heating radiator can calculate by the draught area of heating radiator and the wind speed that flows through, and like this, can think under same rotational speed that the air quantity that passes through is the same.When heating radiator because the air quantity that the tiny foreign material of the dust that adheres to and obstruction cause flowing through is when reducing, the heat that can take away will reduce, and at this moment, needs to strengthen heat radiation, when the air pressure of environment raises, consideration is in the situation consistent by the air mass flow of heating radiator, and air pressure is high, and the heat that can take away is also many, otherwise, air pressure is low, and heating radiator 21 thermal conduction capability will descend, therefore, when air pressure is lower than a certain default atmospheric pressure value, can control and strengthen heat radiation, such as the rotating speed of increase fan, when the heat-sinking capability of heating radiator drops to a certain degree, air pressure is a shade below normal pressure, will increase rotation speed of the fan, to increase heat-sinking capability, perhaps produce a comparison information; When described comparison information represents to process accordingly when dust on the described heating radiator need to be cleared up, when representing that dust on the described heating radiator need to be cleared up, described comparison information produces warning message, perhaps when described comparison information represents that dust on the described heating radiator need to be cleared up, 21 vibrations of control heating radiator so that dust drop etc.
