Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings.
Fig. 1 is a kind of TEC Double-direction Temperature regulator control system schematic diagrames of button cell, including single-chip microcomputer (1), drive module
(2), data acquisition module (3), temperature sensor (4), TEC (5), aluminium sheet (6), heat abstractor (7) and button cell (8).
Single-chip microcomputer is a kind of super low-power consumption, the mixed-signal processor with data acquisition module (3), is used to realize and counts
The communication of calculation machine, temperature data acquisition and the regulation and control to drive module.Detailed process is that data collecting module collected comes from temperature
Data signal, i.e. measured temperature are converted into after the analog signal of sensor.Desired temperature is defeated by computer hyper terminal
After entering, it is compared with measured temperature in singlechip chip, if measured temperature is more than desired temperature, output signal
To drive module so that TEC freezes to battery；If measured temperature is less than desired temperature, driving is outputed signal to
Module so that reversely, heated to battery in TEC supply currents direction；If measured temperature is equal to desired temperature, export
Signal is stopped power supply to drive module to TEC.H-bridge circuit is included in drive module, to realize the change of the sense of current.
Temperature sensor is NTC thermistor, and volume is very small, and sensitivity is high, fast response time.There are two temperature in system
Degree sensor, is individually positioned in the two sides of button cell, the temperature for measuring battery two sides respectively, and then feeds back to each respectively
From drive module, the TEC heating refrigerating states to respective response are adjusted.So further ensure battery two sides temperature
It is consistent, be conducive to experiment research.
The thermal conductivity factor of aluminium is high, low cost, thus system using aluminium sheet as heat conduction medium, as shown in Figure 2.The one of aluminium sheet
Face is in close contact with thermal conductivity factor heat-conducting glue high and TEC, it is ensured that heat transfer is good；There is a circle in the other one side center of aluminium sheet

Cushion rubber (9), rubber width is 1mm or so, the diameter of a diameter of button cell of rubber ring.According to button cell size, groove
Highly it is the half of button cell thickness.Because thermal diffusion speed and distance are inversely proportional, so the thickness of aluminium sheet can not be too thick, greatly
1mm about thicker than the half of button cell thickness.It is conductor additionally, due to aluminium, button cell shell is also conductor, therefore, in order to right
Button cell carries out performance test, it is necessary to spray that one layer of very thin heat conduction is good but nonconducting coating, Ran Houfang in the bottom of groove
Test lead is put, the positive pole or negative pole of button cell are mutually sympathized with corresponding test wiring.It is good in order to ensure system closure,
There are elongate grooves on aluminium sheet to place test lead and thermistor wiring.
When TEC works, heated when while refrigeration in addition.In order to ensure TEC normal works, system has been used and dissipated
Thermal radiates to hot junction, as shown in Figure 2 so that chill surface can be rapidly achieved set temperature value.Heat abstractor includes
Fin and radiator fan, effectively achieve the effect of quick heat radiating.The radiator fan has single electric supply installation.
The application of the TEC Bidirectional temperature control systems that the present invention is provided is button cell, and main logic unit is single
Piece machine.For the design of temperature-regulating module and with heating two working conditions of refrigeration, basic temperature adjustment process is its special character of system：
Set temperature value is input into by computer interface window first, single-chip microcomputer is transferred to by communication module；Then single-chip microcomputer reads
Desired temperature, while reading two measured temperatures of temperature sensor that data acquisition module is collected, and temperature is surveyed
Value returns to computer, is shown in real time.C.T setting value and two sizes of measured temperature in single-chip microcomputer
Afterwards, to drive module in two drive circuits send instruction, and then drive TEC that work is heated or freezed to button cell
Make.Whole temperature adjusting is in dynamic stability process, and during input temp setting value, temperature-regulating module can be made rapidly corresponding anti-
