Abstract

The invention provides a low temperature furnace body and a low temperature dry body temperature calibrator comprising the same. The furnace body comprises a furnace core and a cooling fan; the cooling fan is placed under the furnace core; the furnace core comprises a foaming heat insulator, a constant temperature block arranged inside the foaming heat insulator and integrally foamed, a heat equalizing block installed in the constant temperature block, coolers fixed at two sides of the foaming heat insulator and cooling sheets; and one side of the cooling sheet is contacted with the constant temperature block and the other side is contacted with the heat end of the cooler. The cross section of the constant temperature block in the furnace body is set to be in a shape of an hourglass with two ends wide and the middle narrow, the constant temperature block is light in weight, small in heat capacity and sensitive to temperature changes, and the cooling sheet is large in size and good in cooling effects; and the low temperature dry body temperature calibrator adopts a modular design, the furnace body structure is reasonably laid, the structure is compact, and due to the independent sealing design of two air channels, the furnace body working stability and the temperature measurement precision are improved, and temperature measurement of a low temperature tested device is facilitated.

Description

technical field [0001] The invention belongs to the field of calibration of temperature instruments and meters, and relates to a low-temperature dry body temperature calibrator, in particular to a low-temperature furnace body with uniform temperature field, high heat transfer efficiency and modular assembly and a low-temperature furnace body including the low-temperature furnace body. Dry body temperature calibrator. Background technique [0002] At present, dry body temperature calibrator, especially portable dry body temperature calibrator is widely used in industrial sites, measurement places and laboratories of all walks of life, and has broad market prospects. [0003] In the low-temperature dry body calibrator, during the use of the furnace body, the temperature conditions near it are relatively harsh environmental conditions for some other components, so it is necessary to isolate the surrounding environment from other components. At the same time, as a core componen...
