Embodiment one
With reference to Fig. 1, show the structured flowchart of the temperature control system of a kind of integrated circuit of the embodiment of the present invention one.
The temperature control system of the integrated circuit in the present embodiment can comprise integrated circuit 101, heat conductive silica gel 102, peltier-element 103, temperature sensor 104 and controller 105.Wherein, described peltier-element can comprise refrigeration end, radiating end and current terminal.The annexation of each assembly above-mentioned is as follows: described integrated circuit is connected with described heat conductive silica gel; Described heat conductive silica gel is connected with the refrigeration end of described peltier-element and described temperature sensor respectively; Described controller is connected with the current terminal of described peltier-element and described temperature sensor respectively.
Wherein, can be connected by lead-in wire between controller and the refrigeration end of peltier-element, controller can by the working current of the current terminal adjustment peltier-element of peltier-element, peltier-element is under the effect of this working current, and refrigeration end wherein will produce first heat corresponding with current working current.Being discussed below of paltie effect: when the loop consisted of different conductors electric current, except the irreversible Joule heat of generation, in the joint of different conductor along with heat absorption, exothermic phenomenon can appear in the difference of direction of current respectively.If electric current flows to the lower one end B of free electron number from one end A that free electron number is higher, then the temperature of B end will raise; Otherwise the temperature of B end will reduce.If electric current flows to conductor 2 by conductor 1, then within the unit interval, joint absorption/liberated heat is directly proportional to the current density by joint.Namely after peltier-element is electrified, the heat of refrigeration end is moved to radiating end, causes the temperature of refrigeration end to reduce, and the end temperature of heat radiation raises.
The refrigeration end of peltier-element can connect (such as contacting with the connection between heat conductive silica gel, certain surface contact by the surface of the refrigeration end of peltier-element and heat conductive silica gel), heat conductive silica gel is high-end guides thermalize compound, there is the advantages such as high thermal conductivity, splendid thermal conductivity, the exhausted property of good electricity, wider serviceability temperature, stronger stability in use, lower denseness and good workability, such as short circuit equivalent risk can be avoided.First heat (i.e. low temperature) corresponding with current working current produced can be passed to heat conductive silica gel (as heat-conducting silica gel sheet) by the refrigeration end of peltier-element, and this first heat is passed to described integrated circuit by heat conductive silica gel, thus the temperature of control integration circuit.
Connection between heat conductive silica gel with temperature sensor can for contacting connection (such as, temperature sensor is installed to heat conductive silica gel surface), it (is also the temperature of the refrigeration end of Peltier that temperature sensor is used for according to the temperature value of the described heat conductive silica gel of pre-conditioned measurement, also be the temperature of integrated circuit), and described temperature value is sent to described controller.Wherein pre-conditioned can be measure in real time, and also can be measure according to predetermined period, the embodiment of the present invention not be limited this.
Can be connected by lead-in wire between controller and temperature sensor, controller is after the temperature value receiving temperature sensor transmission, the temperature of contemporary integrated circuits can be learnt, and then the working current of described peltier-element is inputed to according to described temperature value and the target temperature value adjustment of presetting, thus after the working current of peltier-element is adjusted, its refrigeration end produces first heat corresponding with the working current after adjustment, and continue this first heat to be passed to integrated circuit by heat conductive silica gel, and then the temperature of adjustment integrated circuit, till the temperature value (being also the temperature value of integrated circuit) of heat conductive silica gel is equal with described target temperature value.
The temperature of the embodiment of the present invention controls to adopt closed loop feedback system, the working temperature of integrated circuit is recorded by temperature sensor, by controlling the working current of peltier-element, the temperature of dynamic realtime adjustment integrated circuit, reaches the object of stability contorting Integrated Circuit Temperature.In order to improve temperature controlled precision, resolution can be selected in the embodiment of the present invention to be the temperature sensor of 0.5 DEG C, certainly, according to the different requirements to control accuracy, the temperature sensor of other arbitrary resolutions can also be selected, resolution more high control precision is higher, and the embodiment of the present invention is not limited this.
In one preferred embodiment of the invention, when the temperature of integrated circuit is controlled, ensure that the amplitude that the temperature of integrated circuit changes at every turn can not be too large, to avoid because larger change occurs temperature, considerable influence be produced to the performance of integrated circuit.Therefore temperature control curve can be pre-set, this curve is the curve of the corresponding relation describing temperature and time, the temperature such as arranging change per minute (raise or reduce) is how many, and controller can adjust according to the working current of this temperature lowering curve to peltier-element.
When increasing the working current of peltier-element on the basis of the working current in current peltier-element, the first heat that the refrigeration end of this peltier-element produces reduces on the basis of current first heat; Otherwise when reducing the working current of peltier-element on the basis of the working current in current peltier-element, the first heat that the refrigeration end of this peltier-element produces raises on the basis of current first heat.When the working current amplitude of variation of peltier-element is larger, the amplitude of variation of the first heat of the refrigeration end generation of this peltier-element is also larger, otherwise, when peltier-element working current amplitude of variation more hour, the amplitude of variation of the first heat that the refrigeration end of this peltier-element produces is also less.

Such as, temperature control curve is set to change per minute 5 DEG C, and as the working current change x of peltier-element, the time that reaching temperature variation 5 DEG C needs is 2 minutes, as the working current change y of peltier-element, the time that reaching temperature variation 5 DEG C needs is 1 minute.Therefore, when controller receives the temperature value of temperature sensor transmission, if need to reduce by 5 DEG C on the basis of current temperature value, then the working current of adjustment peltier-element makes it increase y by controller, to ensure that the temperature of integrated circuit after 1 minute can reduce by 5 DEG C, thus the requirement of satisfied temperature controlling curve; If need to raise 5 DEG C on the basis of current temperature value, then the working current of adjustment peltier-element makes it reduce y by controller, to ensure that the temperature of integrated circuit after 1 minute can raise 5 DEG C, thus the requirement of satisfied temperature controlling curve.
