Low temperature dry body temperature calibrator

Abstract

The invention provides a low temperature dry body temperature calibrator for temperature calibration on a to-be-detected temperature component. The low temperature dry body temperature calibrator comprises a modularly-designed furnace body, a control board assembly, a system board assembly and a shell, wherein the system board assembly is assembled on the front side surface of the shell; the furnace body and the control board assembly are assembled in the shell; the top surface of the shell is provided with a plurality of cooling holes and is provided with a through hole which is flush with the mouth of the furnace body for accommodating the to-be-detected low temperature component; a gap exists between the top part of the control board assembly and the top surface of the shell; the top part of the control board assembly is provided with a diversion fan; and a deflector that is inclined toward the cooling holes in the top surface of the shell is arranged above the diversion fan. By adopting the modular design, the furnace body and other assemblies and parts can be disassembled independently, and the production and maintenance convenience is thus effectively improved; and the furnace body has a compact structure, the used cooler is light in weight, the cooling efficiency is high, the furnace body working stability and the temperature measurement precision are improved, and the low temperature dry body temperature calibrator is applicable to temperature measurement for the to-be-detected low temperature component.

Description

technical field [0001] The invention belongs to the field of calibration of temperature instruments and meters, and in particular relates to a low-temperature 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 temperature 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 compare the surrounding environment with other components. isolation. At the same time, as a core component, it often needs to be debugged and maintained separately during production and use. Existing products are often locked together with other components. Once a problem occurs, the whole machine needs to be ...
