Abstract
The utility model discloses a cascaded rapid temperature change test chamber which comprises a machine body, a working bin, an air supply device, a first cooling system, a second cooling system, a heating device and a control device. The first cooling system and the second cooling system respectively comprise a compressor, a condenser and a dryer; an outlet pipe of the dryer of the first cooling system is provided with a branch which is connected with a first inlet of a plate-type exchanger, and the branch is provided with an electromagnetic valve; a first outlet communicated with the first inlet of the plate-type exchanger is communicated with an inlet of the compressor of the first cooling system; an outlet of the compressor of the second cooling system is connected with a second inlet of the plate-type exchanger; and a second outlet, connected with the second inlet, of the plate-type exchanger is connected to an inlet of the dryer of the second cooling system. The cascaded rapid temperature change test chamber is stable in work and lower in energy consumption.
Description
Technical field
The utility model relates to a kind of environmental test equipment, specifically the quick temperature changing test chamber of a kind of superposition type.
Background technology
Fast temperature change test is for determining that product at high temperature, low temperature fast or the adaptability of the storage under the climatic environment slowly changed, transportation, use.Process of the test is to using normal temperature → low temperature → low temperature stop → high temperature → high-temperature residence → normal temperature as a circulation.
The security performance test that quick temperature change test is applicable to electronic element provides fail-test, product screening test etc., can improve the reliability of product and carry out the quality control of product.Temperature change test is the test examination of the field indispensabilities such as aviation, automobile, household electrical appliances, scientific research and determines the parameter of the products such as electrician, electronics, car electrics, material after carrying out the temperature environment impact variation of thermocycling and the adaptability of performance use fast, is applicable to the units such as school, factory, military project, research and development.
Need to use quick temperature changing test chamber in temperature change test fast, present quick temperature changing test chamber, adopts single refrigeration system more, its refrigeration usefulness is limited, thereby increase coolant quantity raising cryogenic temperature although can strengthen compressor horsepower, the less stable of its work, and energy consumption is high.
Summary of the invention
The purpose of this utility model is to provide a kind of quick temperature changing test chamber of superposition type that adopts two refrigeration systems.
For achieving the above object, the utility model includes body, working bin, air-supply arrangement, the first refrigeration system, the second refrigeration system, heating arrangement, control device.
