In the utility model, salt bath thermostat using heat fusing after liquid salt as medium, additional cyclone is to carry out
The high temperature thermal field uniformity of mechanical stirring, this process can compare favourably with thermostatic oil bath, and temperature upper limit can reach 700 DEG C.Cyclone,
It circulates the medium in salt bath thermostat at high temperature, improves the uniformity of the thermal field of blackbody cavity, make its isothermal region
Thermal field distribution is more uniform, to promote the emissivity of blackbody radiation source.Blackbody radiation source placement is arranged in salt bath thermostat
Between, black body radiation source device can be put into wherein, guarantee blackbody radiation source can thermally equivalent, and then be blackbody radiation source calibration
Process provides uniform thermal field.The characteristic that due to the medium inside salt bath thermostat there is high temperature melting, low temperature to solidify, it is desirable that put
Enter the black body radiation source device in vallecular cavity and allow for carrying high voltage load, therefore black body radiation source device uses metal shell.
Since thermostat interior media is inorganic salts, the contaminated uniformity that may cause thermal field of medium is interfered, Jie most easy to pollute
Matter is the blackbody radiation source device metal shell being in direct contact with it, and metal occurs to aoxidize the oxidation of Fang Yinghou at high temperature
Object falls off, and can directly result in the uneven of thermal field in vallecular cavity, and then the reproduction for influencing radiation source is horizontal；The oxidation journey of metal shell
Degree is deepened, and the rupture that may cause blackbody chamber is excessive, this will directly jeopardize the personal safety of Field Force, therefore select corrosion resistant
Erosion, oxidation resistant high-temperature alloy material.
Compared with prior art, the utility model has the beneficial effects that
1. the utility model makes full use of the excellent thermal field index of existing salt bath thermostat, by utilizing liquid constant temperature temperature
Degree source device provides better thermal field uniformity index for the reproduction of black body radiation source device, multiple to reach high-caliber fixed point
It is existing.
2. the utility model, as black body radiation source device, is guaranteed by using high temperature resistant, anti-oxidant, corrosion resistant metal
The safety of black body radiation source device, while also ensuring the smoothly progress of blackbody radiation source reproduction process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment；
Wherein, 1. blackbody cavity, 2. thermal insulation materials, 3. heating devices, 4. cyclones, 5. motors, 6. salt bath thermostats,
