The metal bath temperature control system belongs to a dry type temperature control system, liquid medium is not needed as an auxiliary, the occupied space is small, the effectiveness of temperature control is high, the temperature control is stable, and energy saving and environmental protection are achieved.
Description
Technical field
The utility model relates to a kind of thermostatic control metal bath system that detects properties of sample at petroleum chemical industry, is applied to analytical and testing instrument field.
Background technology
Petroleum chemical industry need to be analyzed and test Related product, obtains its parameter characteristic.When using analytical instrument to carry out sample test, need to pass through thermostatic control system, heat, the action such as refrigeration, allow sample in expecting in stationary temperature environment.
In prior art, normally used hot and cold bath system all need liquid do auxiliary media realize heating or refrigeration, thereby control temperature constant, sample is placed in to this type systematic and carries out temperature control, with temperature requirement, change, medium liquid typicalness mainly contains following several: normal temperature water-bath for state, glycerol bath, low temperature alcohol bath for high temperature, other liquid medias of also use that have are done aids in temperature control.Use aforesaid liquid, liquid bath problem points has following: the one, and liquid bath cell body is long-pending larger, need to take the space that instrument is larger; The 2nd, the liquid in bathing needs consuming cost, and otherwise periodic replacement causes waste, meanwhile, change liquid complex steps, consume manpower; The 3rd, liquid bath is when heating or refrigeration, and actual effect speed and constant temperature speed are slow, and energy loss is larger.
Utility model content
For addressing the above problem, the utility model provides a kind of metal bath temperature control system, while being used for testing sample, the temperature constant of heating or refrigeration testing environment is controlled (high temperature, normal temperature and low temperature etc.), the utility model belongs to dry type temperature control system, do not need liquid media to assist, there is little, the temperature of taking up room and control the features such as effective fast, temperature control is stable, energy-conserving and environment-protective.
The utility model is achieved through the following technical solutions:
A metal bath temperature control system, comprises metal bath body, refrigeration unit, heating unit, monitoring temperature unit and control module;
Described metal bath body is the right cylinder made of metal material or the hollow container of rectangular parallelepiped, is provided with the opening of placing test sample on it; Described refrigeration unit is for providing refrigerator pipes or the cold cavity of cold energy by compressor or other low-temperature receiver; Described heating unit is for converting electrical energy into the electrical heating elements of thermal energy; Described refrigeration unit be looped around on the outside surface of metal bath body and with the outside surface laminating of metal bath body; Described heating unit and metal bath body join; The test lead straight cutting of described monitoring temperature unit enters in metal bath body, and the other end is drawn signal wire and is connected with control module; Described control module is connected with refrigeration unit and heating unit respectively by signal wire.
Further, described monitoring temperature unit is by control circuit, to feed back the temperature sensor of monitoring temperature.
Further, described control module is for receiving the signal of monitoring temperature unit, and sends refrigeration or heat signal to the control module of refrigeration unit or heating unit, comprises control circuit and feedback circuit.
The utlity model has following beneficial effect:
(1) the utility model belongs to dry type temperature control system, do not use liquid media to make auxiliary heating or refrigeration, but use electrical heating or cold source equipment sample is heated up or lower the temperature, greatly reduced the volume of test macro, saved the loaded down with trivial details step of changing liquid, meanwhile, low in energy consumption, compared with prior art saving resource and use cost.
(2) temperature control system automaticity of the present utility model is high, and parameter realization property is good, has temperature and controls the features such as effective fast, temperature control is stable, energy-conserving and environment-protective.
