Embodiment Construction

[0061] The object-oriented visualization experiment device based on low-temperature condensation heat transfer of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0062] Such as figure 1 , 2 As shown, an object-oriented low-temperature condensation visualization experiment device includes a vacuum box composed of a sealed vacuum cover 1 and a flange 6, and the flange is provided with an evacuation valve 7, a safety valve 12, an electrical connector Block 14, the interior of the vacuum box is provided with:

[0063] The reboiler is used to contain and vaporize the deep-low temperature liquid. The reboiler includes a tank body 21 and a heating element 23 arranged at the bottom of the tank body. The heating element 23 can be a heating rod fixed at the bottom of the tank body 21 for To provide heat of vaporization for the deep cryogenic liquid, the electric wire 22 of the heating element 23 passes through the electric conne...

Abstract

The invention discloses an object-oriented low-temperature condensation visualization experiment device which comprises a vacuum chamber, a shooting device arranged outside the vacuum chamber, a condensation device and a reboiler, wherein the condensation device and the reboiler are arranged inside the vacuum chamber. The condensation device is provided with one or more visual light window capable of observing condensation state of a heat transferring medium; the vacuum chamber is internally provided with a lighting device; the lighting device comprises one or more annular light source, wherein the one or more annular light source is corresponding to one or more visual light window in a one-to-one correspondence manner; and during detection, a lens of the shooting device is arranged coaxially with the corresponding annular light source and the visual light window. Different visual light windows have corresponding annular LED light sources to carry out object-oriented lighting, thereby guaranteeing uniform light ray distribution and preventing the problem of high-light spot, and solving the problem that vertical lighting and shooting cannot be carried out simultaneously due to crowded space of a light source and a photography instrument in other same-side lighting modes.

Description

technical field [0001] The invention relates to a low-temperature visualization experiment device, in particular to a visualization experiment device using a low-temperature fluid condensation heat exchange illuminated on the same side. Background technique [0002] Industrial gases, known as the "blood" of modern industry, are widely used in iron and steel, chemical industry, medicine, electronics, petroleum, aerospace and other important fields, and their demand is also increasing with the development of economy. At present, industrial gases are mostly separated from air, and the air separation (referred to as air separation) device is a device that produces oxygen, nitrogen and other rare gases from air. The scale of modern air separation plants is constantly developing toward large scale, and the problem of energy consumption has become more prominent. [0003] The main condensing evaporator (referred to as the main cooling) in the air separation unit is a device that c...
