The utility model has the advantages of simple structure and reasonable design, it is with low costs, not only can guarantee the stability and the homogeneity of cold and hot exchange, controlled temperature that simultaneously can be accurate.
Description
Technical field
This utility model relates to thermostatic equipment field, a kind of high accuracy fluid calorstat.
Background technology
Calorstat of the prior art great majority maintain the temperature in calorstat by air-flow, and control accuracy is not the highest, chemical industry cannot be met to a certain extent, medical institutions, in the laboratorys such as scientific research department, various reagent are distilled, it is dried, concentrate and heated at constant temperature processes, or integrated environment is had the requirement of constant temperature and humidity, so fluid calorstat is widely used, but there is the requirement that can not meet high precision test in fluid calorstat of the prior art, inefficiency simultaneously, poor temperature uniformity, time required for reaching design temperature and entering steady statue is long, cause resource and waste of time.
Summary of the invention
In order to solve the problems referred to above this utility model provide one can precise control of temperature, the high accuracy fluid calorstat that work efficiency is high, temperature homogeneity is good.
It is achieved through the following technical solutions to reach above-mentioned technical purpose this utility model:
This utility model is high accuracy fluid calorstat, including shell, portion is provided with zone of heating in the enclosure, outside zone of heating, four sides are equipped with two thermoelectric semiconductor cooling assemblies, cold and hot switching layer it is provided with inside zone of heating, it is equipped with temperature sensor in internal three sides of cold and hot switching layer and bottom, central authorities' flow device it is provided with in cold and hot switching layer bosom position, central authorities' flow device and cold and hot switching layer are equipped with several discharge orifice dredging liquid flowing, central authorities' flow device is connected with hydraulic pump, hydraulic pump is arranged in the interlayer formed below cold and hot switching layer and between zone of heating.
Further improvement of the utility model is: four temperature sensor in the vertical directions are placed equidistant in three sides within cold and hot switching layer and bottom.
Further improvement of the utility model is: four temperature sensors are all connected with the single-chip microcomputer being arranged on shell.
The beneficial effects of the utility model are: pass through shell, zone of heating and cold and hot switching layer will be divided into three layers inside this utility model, utilize the temperature being stratified and set on three sides of cold and hot switching layer gradient different with the temperature sensor measurement of bottom, again temperature parameter is transferred to master control system, master control system controls the element of temperature and starts working after sending signal, when reaching uniform temperature, main frame is opened hydraulic pump and is made it start working, outside liquid is pumped in central authorities' flow device by hydraulic pump, cold and hot exchange is carried out with internal flow by the discharge orifice of the discharge orifice on central authorities' flow device and cold and hot switching layer, when in casing, fluid temperature (F.T.) is constant, it is automatically switched off temperature-controlling system and hydraulic pump, by automatically carrying out cold and hot exchange, ensure that stability and the uniformity of cold and hot exchange.
This utility model simple in construction, reasonable in design, low cost, can not only ensure stability and the uniformity of cold and hot exchange, can be accurately controlled temperature simultaneously.

Detailed description of the invention
In order to strengthen understanding of the present utility model, being described in further detail this utility model below in conjunction with drawings and Examples, this embodiment is only used for explaining this utility model, does not constitute protection domain of the present utility model and limits.
nullAs Figure 1-3，This utility model is high accuracy fluid calorstat，Including shell 1，Zone of heating 2 it is provided with inside shell 1，Outside zone of heating 2, four sides are equipped with two thermoelectric semiconductor cooling assemblies 6，Cold and hot switching layer 3 it is provided with inside zone of heating 2，Internal three sides of cold and hot switching layer 3 and bottom are equipped with temperature sensor 4，Central authorities' flow device 5 it is provided with in cold and hot zone of heating 3 bosom position，Central authorities' flow device 5 and cold and hot switching layer 3 are equipped with several discharge orifice dredging liquid flowing，Central authorities' flow device 5 is connected with hydraulic pump 7，In hydraulic pump 7 is arranged on the interlayer formed below cold and hot switching layer 3 and between zone of heating 2，Temperature sensor in the vertical direction is equally distributed on three sides of cold and hot switching layer and bottom，The liquid of differing heights internal to cold and hot switching layer measures，The temperature signal that temperature sensor sends is weighted after average and setting value contrasts by single-chip microcomputer，Active control system carries out heating and cold and hot exchange to internal liquid，This calorstat can make internal flow carry out uniform cold and hot exchange，Form stable Automatic Cycle，Final stable rear temperature fluctuation is less than ± 1 °，Temperature homogeneity is better than ± 1 °.
This utility model simple in construction, reasonable in design, low cost, can not only ensure stability and the uniformity of cold and hot exchange, can be accurately controlled temperature simultaneously.
