Visual microenvironment constant-temperature and constant-humidity box for interface heat transfer and mass transfer research

Abstract

The invention discloses a visual microenvironment constant-temperature and constant-humidity box for interface heat transfer and mass transfer research. A temperature sensor placement hole and a temperature and humidity air supply inlet are formed in the left side wall of an upper cover; a humidity sensor placement hole, a temperature and humidity air supply outlet and an infrared window are formed in the right side wall of the upper cover; the temperature and humidity air supply inlet and the temperature and humidity air supply outlet are connected with constant-temperature and constant-humidity box pipelines; the bottom edges of the front side wall and the rear side wall of the upper cover are provided with cold and hot fluid thermal insulation pipe U-shaped clamping grooves; a microscopic observation cover plate is arranged on a top plate of the upper cover; a reserved microscope lens hole is formed in the cover plate; a thermocouple and a humidity sensor are mounted in the box; a table is arranged on a bottom plate in the box; a thermal insulation pipe is arranged in the table to convey cold and hot fluids; the thermal insulation pipe penetrates through the cold and hot fluid thermal insulation pipe U-shaped clamping grooves; and a clamping groove mounting experiment flat plate is arranged at the upper part of the table. According to the box, the liquid drop condensation and crystallization processes under the influence of temperature and humidity in the interface heat transfer and mass transfer process can be observed in real time.

Description

technical field [0001] The invention relates to the research field of heat and mass transfer on interfaces of different surfaces, in particular to a visualization box for microscopic phenomena of interface heat and mass transfer in a constant temperature and humidity microenvironment. Background technique [0002] At present, there are many interface experiments that need to control the temperature and humidity of the environment, such as droplet evaporation, interface condensation and crystallization research, but it is difficult to meet the requirements of the temperature and humidity environment in many experiments and visualize the process of frosting. Contents of the invention [0003] The purpose of the present invention is to provide a box for visual observation of the interface heat and mass transfer process in a constant temperature and humidity microenvironment, to realize real-time observation of the droplet condensation and crystallization process of the inter...
