The refrigeration principle of semiconductor cooler 3 of the present invention is
Pass through direct current by two kinds of different semiconductor material strings by the altitude temperature difference effect of semiconductor material refering to attached drawing 6
When the galvanic couple being unified into, heat will be absorbed or released at the both ends of galvanic couple pair.If installing radiator in release end of heat, heat absorbing end is just
Simply and easily semiconductor cooler can be made by heat conveying；When changing direct current direction, and the effect of heating can be reached
Fruit.
After connecting the DC power supply of circuit in Fig. 7, in cold end joint, current direction is n → p, the sky in P-type semiconductor
Free electron in cave and N-type semiconductor leaves moving backwards for connector.Electronics in joint, P-type semiconductor becomes
Free electron leaves a vacancy, that is, hole in P-type semiconductor, that is, produces electronics-hole pair.And newborn
Pass through contact surface enters N-type semiconductor to free electron at once, and at this moment the direction of motion of free electron is opposite with contact electromotive force
, the case where this is with metallic thermocouple hot end, is similar, and electronics gives off energy when passing through connector.However, generating electronics-hole
The energy that the energy that clock synchronization is absorbed is released when passing through connector considerably beyond them.Equally, N-type semiconductor also generates electronics-
Hole pair, newborn hole also enter P-type semiconductor by contact surface at once, generate the energy that electronics-hole clock synchronization is absorbed
The energy released when also passing through connector considerably beyond them.General effect is that the temperature of joint is made to decline and become cold
End, and to absorb heat from external environment, that is, generate the effect of refrigeration.In hot end joint, since electronics-hole is to answering
It closes, gives off energy, outwardly heat release.
(a) peltier effect: when electric current I is by the closed circuit that is combined by two kinds of different materials, in connecing for material
The one end Tou Chu can absorb heat Qp, and the other end can release heat Qp.The heat of this absorption or releasing is called Peltier heat, inhales
Heat or heat release are determined that size is determined by formula Qp=π * I by sense of current.π is Peltier coefficient, is had with thermoelectric power
It closes, π=(α 1- α 2) T, wherein α 1, α 2 are the thermoelectric power for forming the two kinds of materials in circuit, and T is the temperature of associated adapter.
(b) Seebeck effect: the main reason for generating Seebeck effect is the knot that the carrier in hot end is spread toward cold end
Fruit.Such as p-type semiconductor, since the concentration in its hot end hole is higher, then hole is just spread from temperature end to low-temperature end；It is opening a way
In the case of, space charge (there is negative electrical charge in hot end, and cold end has positive charge) just is formed at the both ends of p-type semiconductor, while partly leading
There is electric field in internal portion；When the drift action of diffusion and electric field is cancelled out each other, that is, reach stable state, in semiconductor
There have been the electromotive force due to caused by temperature gradient at both ends --- thermoelectromotive force.Naturally, the temperature difference of n-type semiconductor is electronic
The direction of gesture is to be directed toward temperature end (Seebeck coefficient is negative) from low-temperature end, on the contrary, the side of the thermoelectromotive force of p-type semiconductor
To being that temperature end is directed toward low-temperature end (Seebeck coefficient is positive), therefore can determine whether semiconductor using the direction of thermoelectromotive force
Conduction type.As it can be seen that there is electric field in the semiconductor for having temperature difference, thus at this moment the energy band of semiconductor be it is inclined,
And Fermi energy level therein is also inclined；The difference of both ends Fermi energy level is equal to thermoelectromotive force.
(c) Thomson effect: in metal when non-uniform temperature, the free electron of temperature eminence is freely more electric than temperature lower
Sub- kinetic energy is big.As gas, thermal diffusion can be generated when non-uniform temperature, therefore free electron is high-end low to temperature from temperature
End diffusion comes in low-temperature end heap, to form electric field in conductor, just draws into a potential difference at metal bar both ends.This
Until the diffusion of kind free electron is performed until electric field force to the effect of electronics and the thermal diffusion balance of electronics.
The invention also includes positioning system, positioning system realizes that real time position inquiry and historical position report.Positioning system
It mainly consists of the following parts: battery, microcontroller, mobile data traffic card, signal antenna.As shown in figure 8, the micro-control of positioning system
Device and mobile phone processed carry out data interaction using MQTT transport protocol by Cloud Server, mobile phone terminal and microcontroller by send with
Subscribe to relevant subject information.When operating, user can be by calling time on the setting position app of mobile phone terminal, checking in real time
Location information.Mobile phone terminal can be sent in corresponding subject information and data to Cloud Server, the MQTT clothes built in Cloud Server
Business end can receive corresponding data, be equivalent to and issued a subject information, at this moment microcontroller has subscribed corresponding theme
Information can receive corresponding order, just will do it data processing, and realize corresponding function.
The program of positioning system assists journey Scheduling Framework using Lua language, based on Luat platform, by subscribe to publication come
Realize message mechanism.After function completes an operation, a message can be issued, other functions can subscribe to the message.Journey
The calling with functional module of sequence carries out, as shown in figure 9, microcontroller obtains location information, establishes mqtt client, passes through
Mqtt sends location information to Cloud Server, and cell phone client obtains location information by reading Cloud Server.
