In addition, the temperature/humidity variable value can be obtained in the first time, the responding speed is quick, the detecting sensitivity of the temperature/humidity sensor is improved and the control time is shortened.
Description
Technical field
The utility model belongs to a kind of temperature control testing equipment, particularly relates to a kind of GDJS.
Background technology
GDJS is widely used in electronics, medical treatment, technical fields such as chemical industry, as Fig. 1, shown in 2, existing GDJS, riser is installed in casing, this riser is divided into workspace and temperature adjustment district with described cabinets cavity, described riser is provided with air outlet and return air inlet, described temperature adjustment is equipped with heater in the district, in this temperature adjustment district blowing fan is installed also, this blowing fan is positioned at described air outlet place, blowing fan is blown into the workspace with the hot-air in the temperature adjustment district, air in the workspace flows back to the temperature adjustment district from return air inlet, realize the heat exchange between workspace and the temperature adjustment district, realize the temperature dynamic balance in the GDJS, described temperature adjustment also is equipped with temperature/humidity sensor in the district, and temperature/humidity sensor is mainly used in the temperature/Humidity Detection in the GDJS, and in time send temperature/humidity information to control system, be convenient to control system the duty of heater and humidifier is regulated.
The shortcoming of prior art is: temperature/humidity sensor is positioned at the temperature adjustment district, and the riser between temperature adjustment district and the workspace, all the time there are temperature, humidity difference between temperature adjustment district and the workspace, the response speed of temperature/humidity sensor is slow, detection sensitivity is low, there are obvious errors in the detected temperature of temperature/humidity sensor, humidity data, temperature/humidity data poor reliability.
The utility model content
The purpose of this utility model is to propose a kind of GDJS, can improve the response speed of temperature/humidity sensor, shortens the control time.And can eliminate the obvious errors of temperature/humidity sensor temperature/humidity data, improve the reliability of temperature/humidity data.
For achieving the above object, the utility model provides a kind of GDJS, riser is installed in casing, this riser is divided into workspace and temperature adjustment district with described cabinets cavity, described riser is provided with air outlet and return air inlet, described temperature adjustment is equipped with heater in the district, in this temperature adjustment district blowing fan is installed also, this blowing fan is positioned at described air outlet place, temperature/humidity sensor also is installed in the casing, its key is: described temperature/humidity sensor is positioned at described workspace, and this temperature/humidity sensor is near described air outlet.
Temperature/humidity sensor is installed in the workspace, has avoided temperature, humidity difference between temperature adjustment district and the workspace, has eliminated obvious errors warm, humidity data, improves the reliability of temperature, humidity data.And temperature/humidity sensor more can obtain temperature/humidity changing value the very first time near air outlet, and its response speed is piece more, has improved the detection sensitivity of temperature/humidity sensor.
The upper parallel of described riser is provided with two air outlets, and the lower parallel of this riser is provided with two return air inlets, fixes described temperature/humidity sensor on the sidewall of described workspace, and this temperature/humidity sensor is near one of them air outlet.
Described temperature/humidity sensor is made up of over-temperature sensor, dry bulb sensor and wet bulb sensor, and three sensors also come on the sidewall of workspace.
Over-temperature sensor plays the overtemperature prote effect when work, prevent to add thermal runaway.Temperature and humidity in dry bulb sensor and the wet bulb sensor testing district.Three sensors are side-by-side, and draw close mutually, can improve the precision of temperature detection, make the more aligned property of three's temperature detection result.
Remarkable result of the present utility model is: a kind of GDJS is provided, has eliminated obvious errors warm, humidity data, improved the reliability of temperature, humidity data.And can the very first time obtain temperature/humidity changing value, its response speed is piece more, has improved the detection sensitivity of temperature/humidity sensor, shortens the control time.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, 2: the utility model provides a kind of GDJS, riser 2 is installed in casing 1, this riser 2 is divided into workspace 1a and temperature adjustment district 1b with described casing 1 inner chamber, described riser 2 is provided with air outlet a and return air inlet b, in the described temperature adjustment district 1b heater 3 is installed, in this temperature adjustment district 1b blowing fan 4 is installed also, this blowing fan 4 is positioned at described air outlet a place, temperature/humidity sensor 5 also is installed in the casing 1, described temperature/humidity sensor 5 is positioned at described workspace 1a, and this temperature/humidity sensor 5 is near described air outlet a.
The upper parallel of described riser 2 is provided with two air outlet a, and the lower parallel of this riser 2 is provided with two return air inlet b, fixes described temperature/humidity sensor 5 on the sidewall of described workspace 1a, and this temperature/humidity sensor 5 is near one of them air outlet a.
Described temperature/humidity sensor 5 is made up of over-temperature sensor 5a, dry bulb sensor 5b and wet bulb sensor 5c, and three sensors also come on the sidewall of workspace 1a.
Its operation principle is as follows:
Blowing fan 4 is blown into workspace 1a with the hot-air in the temperature adjustment district 1b, and the air in the 1a of workspace flows back to temperature adjustment district 1b from return air inlet b, realizes the heat exchange between workspace 1a and the temperature adjustment district 1b.Temperature/humidity sensor 5 more can obtain temperature/humidity changing value the very first time near air outlet a, and its response speed is piece more, has improved the detection sensitivity of temperature/humidity sensor 5, shortens the control time.
