Abstract
The utility model relates to a constant temperature instrument box which is characterized in that the utility model comprises a box body, a semiconductor cold dome 7, a temperature controller and two blower fans arranged in opposite directions, wherein, side walls of the box body are transparent double-layered glass, the semiconductor cold dome 7 is used as a refrigerating device or a heat source, the temperature controller is used for measuring the temperature of the box body and for controlling the semiconductor cold dome 7 and the power supply polarity of the two blower fans, and thus, the temperature inside the box body maintains within required temperature range. The utility model is used for placing equipment with a high requirement of a temperature condition in chemical industry production, and has the advantages of electricity saving, small size and portability.
Description
The utility model relates to a kind of constant temperature oven of energy A.T.C.
In chemical process, for example Si Shi viscosity meter of many instruments is arranged, need under constant temperature, work, this often needs to set up separately a temperature control testing laboratory, and this measure will spend higher cost.Work under normal temperature condition as instrument, just must carry out complicated numerical value and convert, this gives directly to measure and brings difficulty.
The purpose of this utility model provides a kind of thermostatical instrument case that can be carried to execute-in-place, and this thermostatical instrument case can be controlled temperature inside automatically.
The purpose of this utility model can realize by following technical proposal:
The utility model comprises casing, semiconductor cold reactor, temperature controller and two blower fans that reverse direction is provided with; The sidewall of casing is transparent double glazing, so that the working condition of insulation and observation box house; Semiconductor cold reactor be arranged at casing on cover, one in two thermal effect face up, one down, on each thermal effect face heat sink is housed all, the top of the heat sink on the thermal effect face down is provided with a distinguished and admirable downward ventilation blower, and the below of the heat sink on the thermal effect face up is provided with a distinguished and admirable cooling fan that makes progress; The temperature measuring head of temperature controller is arranged in the casing, and its temperature control output lead is connected to the power input of two blower fans and semiconductor cold reactor respectively.Temperature in casing is higher than the assigned temperature upper limit, thermal effect face below the temperature controller control semiconductor cold reactor turns cold, and this cold air drops in the casing naturally, and top thermal effect face heating, by the starting of temperature controller control cooling fan, hot-air is blown to casing.Temperature in casing is lower than the assigned temperature lower limit, thermal effect face heating below the temperature controller control semiconductor cold reactor, the starting of temperature controller control ventilation blower, hot-air is blown downwards to casing, and top thermal effect face turns cold, the hot-air that comes out in the casing can carry out heat interchange with the heat sink on the top thermal effect face, so goes round and begins again, and makes the temperature inside the box remain on the temperature range of appointment.
The utility model is compared with prior art: volume is little, be easy to carry, owing to adopted semiconductor cold reactor to carry out temperature control, so control circuit is simple, the control accuracy height.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the electrical connection graph of temperature controller of the present utility model and blower fan and semiconductor cold reactor;
Wherein: 1. direct supply; 2. shell; 3. mercury point contact thermometer; 4. relay; 5. cooling fan; 6. heat sink; 7. semiconductor cold reactor; 8. ventilation blower; 9. transducing plate; 10. base; 11. shelve plate.
With reference to accompanying drawing 1, casing part by double glazing shell 2, base 10, shelve plate 11 and form.Shell 2 is a drum shape, and Qi Dikou is arranged on the base 10, and suitable for reading being stamped of shell 2 shelved plate 11; As temperature-measuring part, relay 4 is as control assembly by mercury point contact thermometer 3 for temperature controller.Mercury point contact thermometer 3 is installed in to be shelved on the plate 11, its temperature measuring head is positioned at the inside of double glazing shell 2, semiconductor cold reactor 7 is installed on to be shelved on the plate 11, the thermal effect face of semiconductor cold reactor 7 belows is provided with transducing plate 9, the thermal effect face of semiconductor cold reactor 7 tops is provided with heat sink 6, in heat sink 6 and the transducing plate 9 slit is arranged all, so that ventilate.The both sides of semiconductor cold reactor 7 are respectively arranged with cooling fan 5 and ventilation blower 8; Cooling fan 5 distinguished and admirable upwards, ventilation blower 8 distinguished and admirable downwards.Alternating current with reference to 2,220 volts in accompanying drawing is converted into 12 volts direct current through transformer and bridge rectifier, and this direct current of 12 volts is connected to relay 4, the contact of the control contact pilot relay 4 of mercury point contact thermometer 3; Temperature in casing is higher than the upper limit to fixed temperature, mercury point contact thermometer 3 pilot relays 4 forwards are connected, and semiconductor cold reactor 7 thermal effect face down turns cold, and cooling fan 5 starts simultaneously, since the effect of diode D1, ventilation blower 8 not electric and stall; Temperature in casing is lower than the lower limit to fixed temperature, mercury point contact thermometer 3 pilot relays 4 are oppositely connected, semiconductor cold reactor 7 thermal effect face heating down, and ventilation blower 8 starts simultaneously, since the effect of diode D2, cooling fan 8 not electric and stall.
