Embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
The containment type reaction tray thermostat that is used for automatic clinical chemistry analyzer as shown in Figure 1, comprise annular closed constant temperature cavity 11, the reaction cup 2 that is hung on reaction tray 1 edge of surrounding the heat-insulation layer 6 of described cavity 11 and being positioned at described cavity 11, also comprise: the well heater between described cavity 11 outer walls and heat-insulation layer 6 inwalls, be positioned at the straight rib fin 12 of described cavity 11 inside bottom wall, be positioned at the aerofoil fan 17 of described cavity 11 bottoms, be positioned at the temperature detect switch (TDS) of described cavity 11 inside bottom wall, and be positioned at the temperature sensor of its setting height(from bottom) at close wall place, described cavity 11 tops a little less than reaction cup 2 diapires.
Described well heater is used for replenishing necessary heat, and described aerofoil fan 17 forces air flow in the chamber, is used to improve the convection heat transfer ability, and the liquid in the reaction cup (2) is warmed up to 37 ℃ and constant temperature in described cavity 11.
As shown in Figure 2, described reaction tray thermostat comprises: temperature control pot 9, photoelectricity seat 10, muff 4, include: the top cover of upper top cover plate 14, heater top 7 and following lamina tecti 15, also comprise: end well heater 8, aerofoil fan 17, reaction tray 1, reaction cup 2, reaction tray driving shaft 3, and not shown: parts such as temperature sensor and support thereof, temperature detect switch (TDS) and control circuit.
Temperature control pot 9, photoelectricity seat 10 and top cover constitute the airtight cavity 11 of constant temperature enclosure jointly.Temperature control pot 9 is the constant temperature enclosure main body, and photoelectricity seat 10 is the support of optical fiber.Temperature control pot 9, photoelectricity seat 10, following lamina tecti 15 use identical materials---aluminium, and contact closely.The high thermal conductivity of aluminium makes that the heat conductivility of constant temperature locular wall is splendid, the fluctuation of the bigger thermal capacity good restraining constant temperature enclosure Inside Air Temperature of aluminium on the other hand on the one hand.Fireless cooker bottom fin 12 and side fin 13 have increased heat transfer area effectively, and it is more even to impel the constant temperature indoor air temperature to distribute.Muff 4 is formed by the special material integral foam, and coefficient of heat conductivity only is 0.05W/m. ℃, and it and upper top cover plate 14 be common to constitute heat-insulation layers 6, and the interference of external environment condition is blocked in outside the temperature controlled compartment effectively.Four aerofoil fans 17 in the temperature controlled compartment are arranged according to specific angle, order about air and flow along the circular passage, have effectively strengthened the cross-ventilation heat exchange of constant temperature enclosure inside.End well heater 8 is the primary heater of constant temperature enclosure, and between the interlayer of temperature control pot bottom and lower shoe 16, it is high temperature resistant, the uniform good characteristic of heating is that uniform distribution of temperature has been created possibility in the constant temperature enclosure.Heater top 7 is auxilliary well heater, is arranged in the interlayer of upper top cover plate 14 and following lamina tecti 15, and it is keeping the temperature of constant temperature enclosure top area effectively.Reaction cup 2 and hot-air are on every side realized the exchange of heat in the mode of Forced Air Convection.The order of transmission of heat is followed successively by: liquid in well heater → constant temperature locular wall → constant temperature room air → reaction wall of cup → reaction cup.Temperature sensor is positioned at the nearly outer wall side of constant temperature enclosure, and the setting height(from bottom) of its support is a little less than the reaction cup diapire, and it is used to respond to the medial temperature of hot-air in the constant temperature enclosure.Temperature detect switch (TDS) is positioned at the constant temperature enclosure inside bottom wall, and it experiences the fireless cooker wall temperature, in case control system is malfunctioning, temperature surpasses predetermined temperature, and the power supply of well heater is cut off in the switch automatic cutout, thereby plays a protective role.Reaction tray driving shaft 3 is used to drive reaction tray 1 rotation.Reaction tray 1 is used to hang reaction cup 2 and makes it rotation.Control circuit is used to control the rotation of the temperature and the reaction tray of constant temperature enclosure, and temperature-controlled process is PID control.
As shown in Figure 3, preheat assembly by preheat top cover 31, preheat bottom 32, preheat in piece 33, fluorine plastic tube 30, pre-heater 29, temperature switch 27, temperature sensor 28, connect flexible pipe 25 and reagent needles 24 is formed.Preheat top cover 31, preheat bottom 32, preheat in the material of piece 33 all be aluminium.Near in temperature sensor 28 impressions preheat piece 33 and fluorine plastic tube 30 contact positions temperature is given control circuit, the pulse width of control heating element pre-heater 29 input ends, thus realize temperature control.Reagent mainly obtained heat in the fluorine plastic tube of several sections winding bendings before entering reaction cup 2, claim the high-temperature region; And reagent needles 24 be connected flexible pipe 25 these two-part reagent and almost do not obtain heat, claim low-temperature space.If remembering the reagent dosage of a proper testing is 1 volume unit, the volume of low-temperature space approximately is 0.2～0.3, and the high-temperature region volume is about 0.7～0.8, and the volume of the fluorine plastic tube 30 of winding bending is about 3.0.Reagent enters reaction cup after about a few second, the reagent of high temperature and the reagent mix of low temperature, and temperature is risen to about 30 ℃ by refrigerated storage temperature, realizes preheating.
As shown in Figure 4, preheating assembly is positioned on the reagent rocking arm 21.Fluorine plastic tube 30 is connected to reagent syringe by the wire hole 26 of afterbody.
