Description of drawings
Fig. 1 is a theory structure sketch map of the present invention.
The specific embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1; The multi-modal coordination temperature control of a kind of double flute thermostat; Comprise low-temperature space thermostat 1 and middle warm area thermostat 2; Be provided with refrigerator, stirring motor, agitator and electric heater in the low-temperature space thermostat 1, and be provided with the liquid cooling heat exchanger 5 that communicates with middle warm area thermostat 2 in the low-temperature space thermostat 1; In be provided with electric heater, stirring motor and agitator equally in the warm thermostat; Middle warm area thermostat 2 is provided with wind cooling temperature lowering loop 3 and liquid cooling cooling-down loop 4; Wind cooling temperature lowering loop 3 communicates with middle warm area thermostat 2 circulations respectively through pipeline with liquid cooling cooling-down loop 4; Be provided with a recycle liquid pump 6 in the liquid cooling cooling-down loop 4, liquid cooling cooling-down loop 4 is connected with low-temperature space thermostat 1 through pipeline, is provided with electric fan 7, air cooling heat exchanger 8 and working medium recycle liquid pump 9 in the wind cooling temperature lowering loop 3.
As shown in Figure 1, be to combine by low-temperature space thermostat and middle warm area thermostat, can be described as a kind of double flute combination thermostat.Wherein, the design of low-temperature space thermostat and the design of conventional low temperature thermostat bath are essentially identical, but in its groove how a heat exchanger that joins with middle temperature thermostat.The function of low-temperature space thermostat, except constant temperature temperature field, cryogenic thermostat district was provided, also promising middle warm area thermostat provided the function of cooling low-temperature receiver.The design of middle warm area thermostat is compared with the design of the thermostat of routine, and how the innovation part has been two kinds of cooling loops: wind cooling temperature lowering loop and liquid cooling cooling-down loop.Because the low-temperature receiver in wind cooling temperature lowering loop is an ambient wind, so can be to working medium cooling far above environment temperature.Because the low-temperature receiver in liquid cooling cooling-down loop is the working medium of low-temperature space thermostat, so can be to the working medium cooling of the operating temperature that is higher than the low-temperature space thermostat.The setting in these two kinds cooling loops, the constant temperature operation temperature area of warm area thermostat is widened greatly and has obviously been accelerated the thermostatic control process in can making.Have only the conventional thermostat of electrical heating means can not be operated in below the environment temperature, the low side temperature spot of its operation temperature area is generally than the high several years of environment temperature, and if want conventional thermostat to be operated in the low side temperature spot, the thermostatic process time can be very long.If use thermostat of the present invention, the low side temperature spot of its operation temperature area can be located at than the low several years of environment temperature, and because the existence in liquid cooling cooling-down loop, its thermostatic process time is very short.A kind of needs are often arranged in the temperature calibration operation, finish the temperature spot of getting back to low numerical value after the calibrating of temperature spot of high value again exactly.At this moment, if realize just having the long especially problem of nature temperature-fall period to exist with conventional thermostat.And use thermostat of the present invention, to can use wind cooling temperature lowering loop fast cooling far above the working medium of environment temperature; To using liquid cooling cooling-down loop fast cooling near the working medium of environment temperature; Thereby saved total calibration operation time exponentially.
Wind cooling temperature lowering loop 3 is made up of electric fan 7, air cooling heat exchanger 8 and working medium recycle liquid pump 9.When thermostatic control process need fast cooling, can start electric fan 7 and working medium recycle liquid pump 8, the working medium in making in the warm area thermostat 2 flows out in groove, through warm area thermostat 2 in flowing back to after air cooling heat exchanger 8 coolings.
Liquid cooling cooling-down loop 4 provides low-temperature receiver by the working medium in the low-temperature space thermostat 1.When central warm area thermostat 2 thermostatic controls need fast cooling, startup recycle liquid pump 6, the working medium in making in the warm area thermostat 2 flow out in groove, warm area thermostat 2 in flowing back to after lowering the temperature through low-temperature space thermostat 1 interior liquid cooling heat exchanger 5.
The specific embodiment of the present invention is described below.
The working medium of low-temperature space thermostat can be selected the liquid of low-temperature working medium such as freezing liquid or other similar performance for use;
The operation temperature area of low-temperature space thermostat can be located at-50 ℃~50 ℃;
The working medium of middle warm area thermostat can be selected the liquid of high-temperature medium oil like transformer oil or other similar performance for use;
The operation temperature area of middle warm area thermostat can be located at 50 ℃~350 ℃.
When the operation temperature area scope of constant temperature point, only use the low-temperature space thermostat, the middle warm area thermostat of stopping using at the low-temperature space thermostat.
When the operation temperature area scope of constant temperature point at middle warm area thermostat, if the constant temperature of middle warm area thermostat point is less than 90 ℃, available low-temperature space thermostat is done the cooling low-temperature receiver of middle warm area thermostat.The numerical value of the thermostat temperature point of low-temperature space thermostat is set by the thermostatic control demand of middle warm area thermostat.For example, the constant temperature of central warm area thermostat is o'clock between 40 ℃~70 ℃ the time, can establish 0 ℃ of the constant temperature point of low-temperature space thermostat.In the middle of the constant temperature of warm area thermostat o'clock between 70 ℃~90 ℃ the time, can establish 10 ℃ of the constant temperature points of low-temperature space thermostat.
When the operation temperature area scope of constant temperature point at middle warm area thermostat, but the constant temperature of middle warm area thermostat o'clock is greater than 90 ℃, the cooling low-temperature receiver of warm area thermostat during the low-temperature space thermostat of then stopping using is done.The wind cooling temperature lowering loop is used in the cooling of middle warm area thermostat instead, and at this moment, middle warm area thermostat and low-temperature space thermostat do not have interactive relation, use in the time of can distinguishing independent same.
The operation temperature area of low-temperature space thermostat and middle warm area thermostat has intersection, guaranteed whole combination thermostat device operation temperature area continuously with complete.As above institute's setting parameter, the operation temperature area of whole thermostat device is-50 ℃~350 ℃.
