This laptop heat-dissipation self-checking device, monitor temperature when notebook runs in real time by temperature sensor, the operational factor of automatic adjusting heat dissipation device, ensure that notebook computer can run at a normal temperature, very intelligent.
Temperature sensor is varied with temperature by object and changes certain characteristic and carrys out indirect inspection.The characteristic of many materials, element all variation with temperature and changing, so the material making temperature sensor is quite a lot of.What temperature sensor caused physical parameter to change with temperature has: expansion, resistance, electric capacity and electromotive force, magnetic property, frequency, optical characteristics and thermonoise etc.
The way of contact of temperature sensor and measured medium is divided into two large classes: contact and contactless.Contact type temperature sensor needs to keep thermo-contact with measured medium, makes both carry out sufficient heat interchange and reach same temperature.This class sensor mainly contains resistance-type, thermopair, PN junction temperature sensor etc.Non-contact temperature sensor without the need to contacting with measured medium, but passes to temperature sensor, to reach the object of thermometric by the heat radiation of measured medium or convection current.This class sensor mainly contains infrared temperature-test sensor.The principal feature of this temp measuring method to measure the temperature of motion state material (as the bearing temperature of the train driven slowly, the temperature of the cement kiln be rotating) and the little object (Temperature Distribution as in integrated circuit) of thermal capacity.
Thermal resistance and thermopair two class is divided into according to sensor material and electron component characteristic.Thermopair is made up of the metal wire of two different materials, welds together at end.Measure the environment temperature not heating position again, just accurately can know the temperature of hot spot.Because it must have the conductor of two kinds of unlike materials, so be referred to as thermopair.The thermopair that unlike material is made is used in different temperature ranges, and their sensitivity is also different.When the sensitivity of thermopair refers to hot spot temperature variation 1 DEG C, the variable quantity of output potential difference.Thermoelectricity for most metals materials for support is sayed occasionally, this numerical value greatly about 5 ~ 40 microvolts/DEG C between.
Because the sensitivity of thermocouple temperature sensor and the thickness of material have nothing to do, also temperature sensor can be made with very thin material.Also the metal material owing to making thermopair has good ductility, and this trickle temperature element has high response speed, can measure fast-changing process.
In a preferred technical solution of the present invention, employing radiator fan is heat abstractor.The principle of work of radiator fan realizes by Conversion of Energy, that is: electric energy → electromagnetic energy → mechanical energy → kinetic energy.Its circuit theory is generally divided into various ways, and the circuit of employing is different, and the performance of fan will be variant.
The technical indicator of radiator fan mainly contains air quantity, blast and rotation speed of the fan.
The total volume of air that air quantity refers to radiator fan discharge per minute or includes in.Air quantity is the most important index weighing radiator fan heat-sinking capability.Obviously, its heat-sinking capability of radiator fan that air quantity is larger is also higher.This is because the thermal capacitance ratio of air is certain, larger air quantity, namely in the unit interval, more air can take away more heat.Certainly, when same air quantity, radiating effect is relevant with the type of flow of wind.
Blast and air quantity are two relative concepts.In general, under the considering that manufacturer is cost-saving, the air quantity that design fan is large, will sacrifice some blast.If fan can drive a large amount of air flowings, but blast is little, (Here it is, and why some rotation speeds of the fan are very high in the bottom that wind just blows less than heating radiator, air quantity is very large, but be exactly the bad reason of radiating effect), on the contrary, blast greatly then often means that air quantity is just little, do not have enough cold airs and heat radiator to carry out heat interchange, radiating effect also can be caused bad.
Fan rotating speed refers to the number of times of electric fan rotation per minute, and unit is rpm.Rotation speed of the fan is by the quantity of the number of turn of motor interior loop, operating voltage, electric fan, inclination angle, highly, diameter and bearing arrangement determine jointly.Rotating speed and fan quality do not have inevitable contact.The rotating speed of fan can be measured by inner tach signal, also can be measured by outside.
