Description
Technical field
The utility model is the reaction tray thermostatic chamber that is applied in the Biochemical Analyzer about a kind of, especially the reaction tray thermostatic chamber of bathing for the air dry type about a kind of thermostatic mode.
Background technology
The project testing of Biochemical Analyzer has high-precision requirement to the temperature degree of accuracy and fluctuation degree, therefore realizes that the thermostatic mode of Biochemical Analyzer is extremely important.At present, the reaction tray temperature control thermostatic mode that is adopted in the automatic clinical chemistry analyzer roughly has following four kinds: the bath of air dry type, water-bath, constant temperature liquid dry type are bathed and solid directly-heated constant temperature.Consider from the structure of simplified apparatus and the angle of reduction maintenance cost, generally adopt the air dry type to bathe.
It is to adopt hot-air that the liquid in the reaction cup is heated that the air dry type is bathed, come the stable of realization response liquid by keeping stablizing of air themperature, simultaneously need adopt axial flow blower to the heat exchange of reactant liquor in the reaction cup, strengthen promptly that the cross-ventilation disturbance comes enhanced heat exchange in the thermostatic chamber in order to strengthen hot-air.But this kind air dry type bath mode has following shortcoming: the 1) NATURAL CONVECTION COEFFICIENT OF HEAT≤10W/m of general air
2. ℃, and need adopt forced-convection heat transfer promptly to strengthen cross-ventilation disturbance in the thermostatic chamber to the heat exchange of reactant liquor in the reaction cup in order to strengthen hot-air, disturbance also causes the inhomogeneities in temperature field in the thermostatic chamber when strengthening, and can influence the temperature control effect of reaction tray; 2) thermal source of general air bath adopts the mode of thermostatic chamber top heater+thermostatic chamber bottom heater or only is that strip heater places the thermostatic chamber side walls, and thermal source is skewness in thermostatic chamber, causes the inhomogeneities of temperature in the whole thermostatic chamber.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and the uniform Biochemical Analyzer reaction tray of temperature thermostatic chamber in a kind of constant temperature chamber is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Biochemical Analyzer reaction tray thermostatic chamber, comprise cavity, this cavity has diapire, roof and connects the annular sidewall of this diapire and roof, this diapire, roof and sidewall cross the constant temperature chamber, this diapire is provided with at least one primary heater, this roof is provided with at least one secondary heater, and this sidewall is provided with at least one the 3rd heater.

The invention has the beneficial effects as follows, the diapire of cavity, roof and sidewall are provided with heater, guarantee the uniformity of the calorie source of whole thermostatic chamber from the thermal source aspect, also guaranteed simultaneously in the air bath Convective Heat Transfer in the whole thermostatic chamber temperature homogeneity of reactant liquor in the diverse location reaction cup.
Description of drawings
Fig. 1 is the longitudinal profile schematic diagram of present embodiment Biochemical Analyzer reaction tray thermostatic chamber;
Fig. 2 is the horizontal section schematic diagram of present embodiment Biochemical Analyzer reaction tray thermostatic chamber.
The specific embodiment
As shown in Figures 1 and 2, present embodiment Biochemical Analyzer reaction tray thermostatic chamber comprises cavity 8, heat-insulation layer 7, primary heater 1, secondary heater 2, the 3rd heater 3 and a plurality of temperature sensor 4.This cavity 8 is made by heat-conducting metal aluminium, it is made up of diapire 81, roof 82 and the annular sidewall 83 that connects this diapire 81 and roof 82, this diapire 81 and roof 82 are all roughly rounded, and this sidewall 83 roughly is annular, and this diapire 81, roof 82 and sidewall 83 cross constant temperature chamber 84.Can place a plurality of reaction cup 6 in this constant temperature chamber 84, each reaction cup 6 can be around central shaft 5 rotations in constant temperature chamber 84.The whole cavity 8 of these heat-insulation layer 7 parcels, promptly this heat-insulation layer 7 wraps up this diapire 81, roof 82 and sidewalls 83, thereby can prevent the interference that external environment changes.In this constant temperature chamber,, still adopted the axial flow blower forced-convection heat transfer to strengthen cross-ventilation disturbance in the constant temperature chamber in order to strengthen the heat exchange needs of hot-air to reactant liquor in the reaction cup.
For the temperature of each point in the comprehensive perception thermostatic chamber, the mode that this thermostatic chamber has adopted multiple spot to arrange temperature sensor.This temperature sensor 4 has three, these three temperature sensors 4 all are fixed on the diapire 81 of this cavity and vertically stretch in this constant temperature chamber 84, these three temperature sensors 4 are 120 degree and evenly distribute, and the setting height(from bottom) of these three temperature sensors 4 is a little less than the diapire of reaction cup 6.The mean value of the temperature data of three temperature sensor 4 collections has been avoided the single shortcoming that can not accurately gather bulk temperature that causes of temperature acquisition point as the mean temperature of hot-air in the constant temperature chamber.Temperature-controlled process is PID control, control cut-offfing of primary heater, secondary heater and the 3rd heater by the average temperature value of multiple spot collection, so just reach the precision control of 37 ℃ of constant temperature, so just guaranteed the uniformity of each point temperature in the whole thermostatic chamber from the temperature acquisition aspect.For this reaction tray thermostatic chamber, it both can all be provided with heater at roof, sidewall and the diapire of cavity, made homogeneous heating; The heater of a ring-type also can only be set at the annular sidewall of cavity, also can reach the purpose of homogeneous heating.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
