The utility model is that the technical scheme that its technical problem of solution adopts is: a kind of low-and high-temp test facility low temp compensating device, comprise apparatus body, be installed on temperature indicator and the power switch of apparatus body outer wall, the temperature controller of apparatus body inside, compressor, evaporimeter, and power supply, described temperature controller and described compressor are series between described power supply L and N end, described temperature controller can be controlled the UNICOM of this circuit, it is characterized in that: also comprise thermoswitch and thermistor, described thermoswitch and thermistor are installed on the inside of equipment, described thermistor is connected with power switch, after described thermoswitch is in parallel with thermistor and compressor be connected between the L of power supply and N end.
As further improvement of the utility model, the temperature spot that described temperature controller and compressor disconnect is 10 ℃.
As further improvement of the utility model, it is 5～10 ℃ that the low temp compensating of described thermoswitch is connected temperature spot.
As further improvement of the utility model, described thermoswitch and thermistor are installed in heat-insulating and sealing box, and described heat-insulating and sealing box is away from evaporimeter.
As further improvement of the utility model, also comprise an indicator lamp, described indicator lamp is connected with thermoswitch, and described indicator lamp is positioned at the sidewall of apparatus body.
As further improvement of the utility model, described thermoswitch is TMS magnetic thermoswitch.
The beneficial effects of the utility model are: the utility model is by being installed on the temperature of the temperature indicator display device exterior of apparatus body outer wall, by power switch, controlling thermistor switches on, make thermistor heating, by thermoswitch, respond to thermistor, make thermoswitch connect circuit, make compressor operation, thereby make low-and high-temp test facility keep refrigeration, make it reach the temperature of test request.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of low-and high-temp test facility low temp compensating device of the present utility model;
Fig. 2 is the structural representation of low-and high-temp test facility low temp compensating device of the present utility model;
Wherein: 1-power supply; 2-power switch; 3-temperature controller; 4-compressor; 5-thermistor; 6-thermoswitch; 7-apparatus body; 8-temperature indicator; 9-evaporimeter, 10-heat-insulating and sealing box; 11-indicator lamp.
The specific embodiment
In order to make those skilled in the art person understand better the utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2: a kind of low-and high-temp test facility low temp compensating device, comprise apparatus body 7, be installed on temperature indicator 8 and the power switch 2 of apparatus body 7 outer walls, the temperature controller 3 of apparatus body 7 inside, compressor 4, evaporimeter 9, with power supply 1, described temperature controller 3 and described compressor 4 are series between described power supply 1L and N end, described temperature controller 3 can be controlled the UNICOM of this circuit, also comprise thermoswitch 6 and thermistor 5, described thermoswitch 6 and thermistor 5 are installed on the inside of equipment, described thermistor 5 is connected with power switch 2, after described thermoswitch 6 is in parallel with thermistor 5, be connected between the L of power supply 1 and N hold with compressor 4.The temperature of temperature indicator 8 display device exterior, when the temperature showing is low, open power switch 2, make thermistor 5 energisings, thereby make thermistor 5 heating, by thermoswitch 6 induction thermistors 5, make thermoswitch 6 connect circuit, make compressor 4 runnings, thereby make low-and high-temp test facility keep refrigeration, make it reach the temperature of test request
Described temperature controller 3 is 10 ℃ with the temperature spot that compressor 4 disconnects.When temperature is during lower than 10 ℃, temperature controller 3 disconnects with compressor 4, and compressor 4 shuts down.
The low temp compensating connection temperature spot of stating thermoswitch 6 is 5～15 ℃.After thermistor 5 heatings, the temperature of thermoswitch 6 inductions reaches while connecting temperature, makes the series circuit of thermoswitch 6 and compressor 4 connect, thereby makes compressor 4 runnings.
Described thermoswitch 6 and thermistor 5 are installed in heat-insulating and sealing box 10, and described heat-insulating and sealing box 10 is away from evaporimeter 9.Heat-insulating and sealing box 10 has effect of heat insulation, and away from evaporimeter 9, the heat of thermistor 5 just can not absorbed by evaporimeter 9 like this, thereby makes thermistor 5 can not be subject to the impact of external environment condition.
