Description
Technical Field
The invention belongs to the technical field of precise microenvironment control, and particularly relates to a multimode composite double-layer ultra-precise temperature control device.
Background
With the continuous improvement of ultra-precise machining and measuring level, disturbance of environmental parameters such as temperature, humidity, pressure, cleanliness and the like becomes a key factor for restricting the improvement of precision and performance of ultra-precise machining equipment and measuring instruments. Ultra-precise manufacturing equipment such as scanning tunnel microscopes and the like, photoetching machines and the like, has extremely high technical concentration and complexity, and each key index reaches the limit of the prior art capability and represents the highest level of current measurement and processing and manufacturing. Ultra-precise environmental control becomes a key technology of ultra-precise machining equipment and measuring instruments.
In the prior art, patent document with the application number 201810171584.7 discloses a temperature control mode of normal pressure heat radiation: the coarse temperature control clamping cylinder is used for carrying out radiation coupling temperature control on the precise inner temperature control Wen Tongre, and the precise inner temperature control cylinder is used for controlling the inner temperature in a heat radiation mode. The temperature control mode designed by the method omits the heat convection effect of air under normal pressure, and the temperature control power of the coarse temperature control clamping cylinder and the precise inner temperature control cylinder is actually the result of mutual coupling of heat radiation and heat convection because no corresponding decoupling measures are adopted. Therefore, the characteristic of high heat radiation temperature control precision in the scheme is not exerted. The patent document of application number 202110647092.2 discloses a high-precision temperature control device for cross radiation convection, which adopts a temperature control mode of cross radiation convection, and liquid from a water chilling unit is sent to a water separator after passing through a first fine adjustment heating device and a second fine adjustment heating device, and the water separator uniformly sends the liquid to the cross radiation convection device. The flow of the cross radiation convection device is adjusted through the water pump frequency conversion, the heat source change on the measuring platform is automatically adapted, the heat exchange efficiency is improved, the temperature of the water collector is precisely controlled through the fine adjustment heating device, and the purpose that the temperature of the measuring platform is controllable and adjustable is achieved. However, the scheme does not give enough radiation versus temperature control details, and according to the description of the invention, the convection and radiation power of the device cannot be completely decoupled, so that the advantages of high-precision temperature control of heat radiation and rapid temperature control of heat convection cannot be exerted.
Furthermore, the conventional temperature control method only considers the dominant heat transfer method. When the temperature of the circulating water is controlled, only the effect of heat conduction is considered (Zhao Yiwen. Research on immersion liquid high-precision temperature control technology based on active disturbance rejection control. University of science and technology, 2107.); the temperature control of the gas bath is performed by considering only the thermal convection (Zhao Jiangjun. Model and algorithm for the internal gas temperature control of lithography, university of science and technology, 2107.). The single temperature control mode is more and more difficult to meet the requirements of occasions such as industrial production, and the ignored heat transfer mode becomes an important factor for limiting the temperature control precision. Therefore, the vacuum radiation temperature control scheme adopted by the molecular measuring machine developed by NIST suppresses natural convection of air, the copper shell coated by the resistance heating wire coats the measuring core, the surfaces of the shell and the measuring core are plated with matte gold to keep the radiation coupling stability (1.Kramar J,Jun J,Penzes W,et al.THE MOLECULAR MEASURING MACHINE.2008;2.USDepartment of Commerce,NIST.Nanometer Resolution Metrology with the NIST Molecular Measuring Machine.Measurement Science&Technology.). between the shell and the measuring core, the scheme can realize temperature control precision of the magnitude of +/-0.001 ℃, but the response time of the scheme is as long as days or even months, and the requirement of ultra-precision machining manufacturing on efficiency is difficult to meet.
In summary, the requirements of ultra-precise instruments and large ultra-precise manufacturing equipment on micro-environment parameter control are increasingly higher, and the traditional single temperature control mode has low precision and long adjustment time; the composite temperature control mode does not decouple each temperature control power, and cannot exert the advantages of the temperature control precision and efficiency of the composite temperature control mode. None of the above techniques meets the requirements of precision and efficiency of ultra-precision machining equipment and measuring instruments.

The multimode composite double-layer ultra-precise temperature control device provided by the invention has the following advantages:
(1) The invention adopts a temperature control method compounded by a plurality of heat transfer modes, and improves the temperature control precision and efficiency. The device is provided with a circulating medium pipe for controlling the temperature in the primary steel plate sealing box the secondary steel plate sealing box is provided with a radiation convection dual-mode composite temperature control plate for circulating cooling medium to enter the secondary steel plate sealing box for multi-mode temperature control.

The conduction cooling effect of the cooling component mainly depends on a circulating cooling medium, and temperature crosstalk cannot be formed between the cooling component and the dual-mode composite temperature control mechanism. The radiation plate and the convection assembly are isolated by the heat insulation layer, so that the problem of coupling of composite temperature control power can be solved, advantages of different temperature control modes are complementary, and the problems that the temperature control power of different temperature control modes is difficult to decouple and interfere with each other in the composite temperature control mode of the traditional instrument are solved, and the temperature control precision and efficiency of the composite temperature control mode are difficult to effectively exert are solved. This is the second point of innovation of the present invention to distinguish from the prior art.
