Embodiment
Fig. 2 is the stereogram that the utility model can be detected a preferred embodiment of heat abstractor of stream condition.As shown in Figure 2, the heat abstractor that the utility model can be detected stream condition is arranged in the electronic product, the heat that produces when being used for discharging electronic product work.For illustrate clear for the purpose of, below be the example explanation with notebook computer 300.
Notebook computer 300 has a casing 32 that defines air channel 31, and CPU 400 is arranged in the air channel 31 so that heat radiation, and air channel 31 comprises opposite an inlet air end 311 and an air-out end 312.For illustrate clear for the purpose of, the air channel 31 among Fig. 2 presents schematically.But it will be appreciated by those skilled in the art that air channel 31 herein not necessarily has particular conduit, so long as the passage for circulation of air that forms between the circuit element in this casing 32 all can be referred to as the air channel.Heat abstractor 4 is arranged in the notebook computer 300 and with air channel 31 and is connected.Heat abstractor 4 has 5, one blasting units of a blast pipe, and a detecting unit.
As shown in Figure 3, Figure 4, detecting unit is a measuring wind speed meter 7 that is arranged in the blast pipe 5, has a rot 71 that is arranged in the blast pipe 5 and can be driven rotation by the gas that fan 6 drives, the light source 72 of stabilized illumination after startup, the light source recipient 73 that can receive the light that light source 72 sent, and a calculator 74.
Light source 72 and light source recipient 73 are arranged at opposite two sides of the rotor 712 of rot 71.When rotor 712 rotated, if 711 light that light source 72 sent over against light source 72 of boring a hole can pass a perforation 711 of rotor 712, then light source recipient 73 can receive light signal one time.
Calculator 74 according to light source recipient 73 actual reception to light signal carry out operational analysis.Because the speed decision light source recipient 73 that rotor 712 rotates receives the frequency of light signal, so when this frequency is lower than a predetermined value (being that rotor rotation speed is slow excessively) or be zero (being that rotor stops operating), promptly represents the blast deficiency of this heat dissipation wind channel or be windless condition.Can be that a heat radiation signal exports in the notebook computer 300 this moment with this state exchange.Notebook computer 300 can be according to this signal that dispels the heat, send alarm sound or on display display message, notify the air flow condition in the present heat abstractor of user undesired, can't provide enough heat radiations for CPU 400.
When notebook computer 300 start work, CPU 400 beginning computings also produce heat, the fan 6 automatic entrys into service of heat abstractor 4 simultaneously, and the air that drives in the blast pipe 5 is flowed to air outlet 52 directions by air intake vent 51.Simultaneously, the rot 71 that air flows in the blast pipe 5 drives measuring wind speed meter 7 rotates, calculator 74 according to light source recipient 73 actual reception to light signal carry out operational analysis, with this moment rot 71 rotary state be converted to the heat radiation signal and export in the notebook computer 300, the user learns in view of the above whether the flow rate of air in the present heat abstractor 4 is normal, and then learns whether the heat extraction state of operational environment of present CPU 400 is normal.
When the user normally uses notebook computer 300, this heat abstractor 4 can drive air-flow really, and the air that the external world is colder is introduced, and the air that CPU 400 environment temperatures are higher is discharged notebook computer 300, thereby reduce the operating ambient temperature of CPU 400, CPU 400 is remained under the normal working temperature move.
When under abnormal condition, using notebook computer 300, for example the user is placed on notebook computer 300 on the leg and uses, perhaps notebook computer 300 must be placed in a lot of foreign material and use, if the inlet air end 311 of notebook computer 300 is by external impurities, for example user's clothes, extraneous institutes such as other article of stacking block, even complete closed, and make heat abstractor 4 can't be from the inlet air end 311 suck outside airs, although cause fan 6 still in running, be calm in air channel 31, the blast pipe 5 or windless condition almost.At this moment, because the rot 71 of measuring wind speed meter 7 can't be driven by flow air and rotate, calculator 74 can reach the heat radiation signal of conversion this moment in the notebook computer 300, send alarm sound by the display warning or by loudspeaker, remind the user to check the environment for use of notebook computer 300 or the state of heat abstractor 4.When situation was urgent, the heat radiation signal of calculator 74 transmission can be forced notebook computer 300 shutdown, with protected data and CPU 400.
Need to prove that in the above-described embodiments, the air intake vent 51 of blast pipe 5 is connected with the inlet air end 311 of notebook computer 300, rot 71 is arranged in the blast pipe 5.But, detailed description by the foregoing description as can be known, the air intake vent 51 of blast pipe 5, air outlet 52 also nonessentially is connected with inlet air end 311, air-out end 312, the also also nonessential air channel 31 that is arranged in of blast pipe 5 is as long as any one among both of air intake vent 51, air outlet 52 communicates with air channel 31.In addition, detecting unit is also nonessential to be the employed optical profile type measuring wind speed of the foregoing description meter 7, can also use in the wind pressure measurement of induction air pressure as principle.When using measuring wind speed meter 7, the position of rot 71 can be in blast pipe 5, also can be in air channel 31, and carry the position that all places that air that heat that CPU 400 produces leaves notebook computer 300 flows through all can be considered as rot 71, because these positions are a lot, do not enumerate one by one at this.
In addition, because the blast pipe 5 that the utility model can be detected the heat abstractor 4 of stream condition is to be that material is made with the metal with high heat-conduction coefficient, therefore, the all available heat-conducting glue of the CPU 400 of notebook computer 300 or other heat-generating electronic elements is connected in blast pipe 5, the heat that when work produced by this heat-conducting glue and blast pipe 5 with conduction pattern diversion element faster itself, thereby make the use of notebook computer 300 more smooth and easy, stablize.
As shown in the above description; the utility model can be detected the heat abstractor 4 main flow regimes of using detecting unit to measure the air of help electronic product heat radiation of stream condition; and then make the user learn the radiating state of electronic product; and adopt auxiliary forced shutdown mode to protect user's data and electronic product itself, thereby realize the purpose of this utility model.
