Described heating element heater adopts the PTC ceramic thermal resistance, according to the PTC effect, selects the heating element heater of suitable Curie temperature to control the output temperature of warmer at the energy output end, improves the safety of warmer.Very large semi-conducting material or the components and parts of PTC (Positive Temperature Coefficient) general reference positive temperature coefficient.The ceramic PTC critesistor is the semiconductor resistor that a kind of typical case has temperature sensitivity, and when surpassing certain temperature (Curie temperature), its resistance value is along with the rising of temperature is increasing of step evolution.
Described temperature control comprises temperature display system, temperature control system, temperature measurement system, safe-guard system.Temperature measurement system detects the heat-conducting plate rate of temperature change, and detected value is transferred to single-chip microcomputer, single-chip microcomputer carries out corrected Calculation according to program with the data that receive, result of calculation is transferred to demonstration, single-chip microcomputer carries out PWM calculating heating plate is carried out PID control heating simultaneously, and adding thermal result will feed back to single-chip microcomputer by system for detecting temperature.Go round and begin again successively until temperature reaches the transfusion requirement.
Described sensor adopts PT1000 to do temperature sensor, adopts XTR105 to do the processes temperature signal chip, and the temperature detection peripheral circuit is simple, strong anti-interference performance.
Compared to existing technology, the present invention has following beneficial effect:
1, conducting-heat elements is selected the aluminium sheet compression molding process and has been initiated serpentine transfusion groove mechanical engraved structure, has effectively promoted conduction of heat and utilization rate, and the warmer volume is little, and (160mm * 80mm * 35mm), quality light (450g), heat conduction are fast.
2, heating element heater is placed heat-conducting plate inner, send electricity by ABS insulant and the isolation of sil-pad dielectric film.Can improve the thermal efficiency and can avoid again the heat build-up of components and parts, also improve the packaging technology of warmer simultaneously, reduce overall volume.
3, PID calculates, PWM control heating, and the temperature acquisition data are through PID calculating, can preset temperature, and raising warmer control accuracy prevents temperature overshot; Adopt PWM to export by photoelectrical coupler control controllable silicon, the heating of SCR control heating plate prevents fixing heating frequency, controls heat time heating time.This structure can improve warmer control accuracy and realtime control, makes warmer use safer and can reduce interference to utility grid.
4, temperature measurement system detects the rate of change of heat-conducting plate temperature, and single-chip microcomputer is provided by the heat that provide, and by different temperatures compensation program control heating, has realized the stable control to the liquid output temperature.
5, flow velocity compensation heating.Satisfy the requirement of different in flow rate, the temperature-compensating program of design different in flow rate in program.Detect the rate of temperature change of conducting-heat elements, according to the variation speed measuring and calculating transfusion speed of rate of temperature change, revise heating parameters, can effectively reduce the interior flow velocity of certain limit to the impact of heats.
6, the one-touch work of starting shooting from designing the temperature that reduced between ambient temperature, each passage and infusion flow-rate to the impact of transfusion effect, can be accomplished a key selection job after the start, need not to arrange.
7, warmer is when choosing of heating element heater guarantees temperature overshot.Inner overcurrent protection, the protection of civil power electrical isolation and the special-purpose excess temperature of also being provided with forced cut-off switch.And between lid and box body, place the lid sense switch, can effectively guarantee operator's personal safety.
