The liquid nitrogen low-temperature box is characterized in that the liquid nitrogen low-temperature box comprises a liquid nitrogen storage tank (1), a low-temperature electromagnetic valve (2), a low-temperature box body (3), atomizing nozzles (4) and a temperature sensor (5), wherein the low-temperature box body (3) is internally provided with a cooling pipeline (3-1); an outlet pipeline of the liquid nitrogen storage tank (1) communicates with an inlet of the cooling pipeline (3-1) through the low-temperature electromagnetic valve (2); the atomizing nozzles (4) are arranged on the cooling pipeline (3-1) and face the interior of the low-temperature box body (3); the temperature sensor (5) is arranged on the wall of the low-temperature box body (3); and the temperature sensor (5) is connected with the low-temperature electromagnetic valve (2), so that opening and closing of a valve door of the low-temperature electromagnetic valve (2) are achieved.

Description

A kind of liquid nitrogen cryogenics sweat box
Technical field
The invention is widely used in semi physical low-temperature test environment, it is desirable to rate of temperature fall is fast, temperature control precision is high, environmental pollution is little, improves test preparation efficiency.
Background technology
Traditional semi physical low-temperature test environment adopts the mode of compressor cooling, is generally adopted two stages of compression, and operation principle is complicated, and the control of equipment requires higher, and the device fabrication cycle is long, and manufacturing cost is higher, and maintenance cost is also high.Equipment is easily damaged.
Summary of the invention
The purpose of the invention:
Study a kind of novel full-automatic liquid nitrogen cryogenic temperature case.Realize that rate of temperature fall is fast, temperature control precision is high, environmental pollution is little, improve test preparation efficiency.
The technical scheme of the invention:
The invention provides a kind of liquid nitrogen cryogenics sweat box, it is characterized in that, liquid nitrogen storage tank (1), low-temperature solenoid valve (2), cryostat (3), atomizer (4), temperature sensor (5), cooling line (3-1) it is provided with in cryostat (3), the export pipeline of liquid nitrogen storage tank (1) is connected with cooling line (3-1) import by low-temperature solenoid valve (2), cooling line (3-1) is provided with atomizer (4), atomizer (4) is internal towards cryostat (3), temperature sensor (5) is arranged on the wall of cryostat (3), temperature sensor (5) is connected with low-temperature solenoid valve (2) and realizes the opening and closing of low-temperature solenoid valve (2) valve.
Further, it is additionally provided with pressure transducer (7) and Unidirectional solenoid valve (6), pressure transducer (7) is arranged on the wall of cryostat (3), the opening part on the top of Unidirectional solenoid valve (6) cryostat (3), pressure transducer (7) is connected with Unidirectional solenoid valve (6) and realizes the opening and closing of Unidirectional solenoid valve (6) valve.
Liquid nitrogen is by liquid nitrogen storage tank (1) by low-temperature solenoid valve (2) access arrangement internal cooling pipeline (3-1), and the control of liquid nitrogen flow is controlled in the way of dutycycle by low-temperature solenoid valve (2).Liquid nitrogen adopts single point injection to inject, atomizer release evaporative cooling.Ambient temperature in case is automatically down to setting value by the temperature sensor (5) of cryostat (3) within the time allowed, and when the temperature inside the box is down to setting value, electromagnetic valve automatically cuts off.
