Description
Technical field
The invention belongs to high temperature and high voltage experimental device technical fields, and in particular to a kind of to be suitable for high-temperature high-voltage reaction just
Take formula visualization heater and cooler device.
Background technology
It, be to reaction process and reaction product under high temperature high confining pressure in the experimentation of aqueous fluid-solid interaction
In-situ observation is carried out, needs optical window is arranged on the heating and sample is observed, but because of high temperature at optical window
Heating can damage optic probe, and common heating furnace causes optics to visit due to needing very thick heat preserving and insulating material
Head test coupon is far so that optical resolution is difficult to improve, and the high temperature at optical window can cause the infrared spoke of background
Blackberry lily is disturbed so that test data noise is relatively low.In addition there is also following shortcomings for the prior art：
1）Insulating layer is blocked up, and volume is excessive, whole heavier；Since insulating layer is thicker, even if opening optical window on heating furnace
Mouthful, in optical path direction, distance of the microscope apart from sample is still very remote so that the operating distance of object lens is very big, numerical aperture
Diameter is with regard to very little, so that areas imaging reduces, spectral signal is very weak；
2）If Heating Furnace is conducted heat using copper plate, in high temperature section（Such as it is higher than 500 degree）, the easy oxidation of copper plate
It peels off, heating furnace damages soon；
3）The heating layer of existing heating furnace winds burner hearth using heater strip, and annular-heating silk is electrified stream, it is easy to generate electromagnetism
Effect, to which there may be interference, such as linear variable difference transformer LVDT to other measuring cells；
4）As by the way of big pipe sleeve tubule, the sealing between big pipe and tubule needs to weld the cooling layer of existing heating furnace,
And it welds and there are problems that being easily deformed and leak；
5）For the cooling layer of existing heating furnace as by the way of big pipe sleeve tubule, the heat that cooling water is taken away is more, and heater strip needs
It wants very big power temperature could be gone up, therefore heater strip is easy fusing and consumes a large amount of electric energy, and to add
Hot stove entire length is longer so that exerted oneself bar is longer, deformation of the longer power bar of length under identical stressing conditions compared with
Greatly, the larger deformation of power bar causes large error to the deformation measurement of sample；
6）Optical window will be arranged on stove, then cool down as by the way of big pipe sleeve tubule for the cooling layer of existing heating furnace
For layer in the position of optical window, there are the dead angles of flow of cooling water, cause water flow velocity uneven, so that cooling temperature is uneven
It is even；
7）The cooling layer of existing heating furnace is such as by the way of big pipe sleeve tubule, in water inlet one end of cooling water than water outlet
One end furnace temperature is low, i.e., cooling is uneven；
8）If existing heating furnace is insulated using refractory ceramics plate, there are problems that being easy cracking, and high temperature resistant is made pottery
The cost of porcelain plate is higher.
