Abstract

The invention discloses a box body of a multi-parameter integrated measurement verification experimental box for temperature, humidity and pressure, which consists of a shell, a liner, a left guide cylinder, a right guide cylinder, a left metal pore plate, a right metal pore plate, a gas inlet, a gas outlet, a general inlet of a heat exchange liquid, a general outlet of the heat exchange liquid, a temperature control sealing door and a door frame, wherein the liner is arranged on the middle part inside the box body; the left cylinder and the right guide cylinder are respectively positioned inside the left and the right of the box body; the left metal pore plate and the right metal pore plate are arranged between the left guide cylinder and the right guide cylinder; the gas inlet is connected with the left guide cylinder; the gas outlet is connected with the right guide cylinder; the general inlet of the heat exchange liquid and the general outlet of the heat exchange liquid are respectively connected with corresponding outlet and inlet on the liner; the temperature control sealing door is arranged in the centre in front of the box body and is tightly adhered to the door frame; theoverall box body is enclosed by the shell; and a heat insulating material is filled between the shell and the liner. The experimental box body has the advantages of scientific design, novel structureand rationally designed diffusion structure so that a gas can diffuse into the overall space in the box body uniformly and quickly, which solves the problems that the conventional box body only aims at a single parameter, that the temperature and the humidity of a gas flow field are non-uniform, and that the heat insulation is not tight and the like; and therefore, the box body has wide application prospect.

Description

(1) Technical field

[0001] The invention relates to a temperature, humidity and pressure multi-parameter comprehensive measurement test box body. The box can provide a wide range of temperature, humidity and pressure, and a highly uniform environment for comprehensive measurement and verification of temperature, humidity and pressure. (2) Background technology

[0002] The temperature, humidity and pressure comprehensive measurement and verification experiment box is specially designed to provide a uniform temperature and humidity environment under a certain pressure. This uniform temperature, humidity, and pressure environment is obtained by transforming the saturated moisture generated by the previous device through the principle of double temperature and double pressure. The change of one parameter or the simultaneous change of multiple parameters is a routine requirement for temperature, humidity and pressure verification experiments. The current temperature, humidity,...
