Problems solved by technology

At present, the common thermostatic bath used in the high-precision temperature maintenance device has only one kind of temperature-regulating medium, and the temperature-regulating range is small.
In addition, the heat preservation part and the temperature regulation part of the common constant temperature tank are usually set in the same closed device, which can only be used under static conditions.
In some specific occasions, such as in the

Abstract

The invention discloses a constant temperature bath. The constant temperature bath is used as a temperature regulating and maintaining device, and particularly suitable for an acceleration-temperature compound calibration device. The constant temperature bath comprises a first medium constant temperature bath body (11), a second medium constant temperature bath body (12), a liquid returning tank (13), a circulating pump (14), a solenoid valve (15, 15'), a heat exchange connector (16, 16'), a heat exchanger (17) and a pipeline (18) connected with each component. After the heat conduction medium is heated or cooled by the first medium constant temperature bath body (11) or the second medium constant temperature bath body (12), the heat conduction medium is flowed into the heat exchanger (17), where the calibration device is positioned, by the pipeline (18) through the circulating pump (14), the solenoid valve (15) and the heat exchange connector (16), and the heat conduction medium is returned to the liquid returning tank (13) through the heat exchange connector (16') and the solenoid valve (15'), finally the heat conduction medium is respectively flowed into the first medium constant temperature bath body (11) or the second medium constant temperature bath body (12) through a first medium liquid returning tank circulating pump (305) or a second medium liquid returning tank circulating pump (306).

Description

technical field [0001] The invention relates to a constant temperature tank, in particular to a dual constant temperature tank suitable for acceleration-temperature compound calibration equipment, and belongs to the technical field of inertial device compound measurement calibration. Background technique [0002] The constant temperature bath can provide a high-precision constant temperature field source. Specifically, the target temperature is generally maintained at the set temperature by adjusting the temperature of the medium in the tank. The constant temperature bath can be used in fine chemical industry, biological engineering, medicine and food, scientific experiment, metallurgy, petroleum, agriculture and other fields. At present, the common thermostatic tank used in high-precision temperature maintenance devices has only one kind of temperature-regulating medium, and the temperature-regulating range is small. In addition, the heat preservation part and the temperat...
