A precooler arranged on the top plate of the box body is communicated with a low temperature liquid tank by an infusion pipe and an adjusting valve, and thus the temperature lowering device is made up. The bottom plate of the box body is provided with a hot air distributing pipe. The wall surface of the box body is provided with at least a blower air entry which is communicated with an electric heater and is communicated with the hot air distributing pipe on the bottom of the box body to form the temperature rising device. Compared with the prior art, the utility model has the characteristics of quick temperature rising and lowering, large temperature range of high and low temperature, broad range of application as the utility model can not only be applied to small volume test boxes, but can also be applied to large volume test boxes or structural assemblies with multi-box bodies, etc, convenient and reliable temperature regulation and controlling, and high fidelity of the simulated environment which is beneficial to accurate data of the test, etc.
Description
Technical field
The utility model relates to a kind of the sealing environment in can control gradient of temperature so that the simulated environment equipment that in the uniform temperature changing environment, experimentizes.
Background technology
Carry out the environment temperature control of high temperature or low temperature in the space of a sealing, be widely used in the laboratory of industry or scientific research institution so that produce a simulated environment that is fit to test.The regulation and control that realize local intensification or cooling in the space of a sealing and be able to temperature have belonged to a mature technique, because the application of Refrigeration Technique can realize local cooling, and the application of electric-heating technology can realize local intensification.Disclose the application for a patent for invention technology of " energy-saving low-and high-temp test facility " on the Chinese patent communique, application number is: 92108365.3, and this technology adopts electric heater that chamber is carried out local heat and made its intensification; Adopt the improved formula refrigeration system that changes again that chamber is cooled, dispose the local temperature regulation and control that control corresponding equipment and instrument are carried out chamber simultaneously.Electric-heating technology and Refrigeration Technique have mainly been used in the intensification of above-mentioned low-and high-temp test facility and cooling, though and the suitable maturation of existing Refrigeration Technique, but its general chamber to low capacity has cooling-down effect preferably, in case the space increases, the just obvious variation of cool effect, especially Jiang Wen speed reduces; The temperature range of its high and low temperature environment that can reach is limited in addition, can't adapt to the test requirements document that some needs wide temperatures change.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of big capacity high and low temperature environment experimental facilities that mainly carries out spraying cooling with cryogenic liquid is provided, it includes the casing of at least one closed, and the heat riser and the heat sink of configuration, on the top board of casing, forecooler is installed, this forecooler is connected with cryogenic liquid tank through woven hose and control valve, and constitutes heat sink; And the hot gas distributing pipe is installed on the base plate of casing, and at least one air blast air entry is installed on the wall of casing, it is connected with an electric heater, and the formation heat riser that communicates with the hot gas distributing pipe of bottom half.
Described precooling organ pipe is outside equipped with fin, and the one side is equipped with the gas distributor of being made up of a plurality of nozzles that is communicated with low temp liquid evaporator, and low temp liquid evaporator is communicated with forecooler.
Described casing is the clad steel shelf structure, and the centre is filled with the expanded perlite thermal-nsulation material layer, is provided with the electronic isolating door of a fan on the limit wall of casing at least.
The utility model compared with prior art, because the main directly spraying cooling of cryogenic liquid gasification back that adopts, thereby it is fast to have heating-cooling speed, the temperature range of high low temperature is big, and temperature adjusting is convenient and reliable, the validity height of simulated environment, it is accurate to help test for data, both can be used for the chamber of little volume, more be applicable to the chamber of big volume or the textural association of many casings etc., characteristics such as applied widely.
