Lifting type cold-hot impact tester

Abstract

The invention relates to the technical field of test equipment, and particularly relates to a lifting type cold-hot impact tester. A control panel is arranged on a rack body, a refrigerating box body and a heating box body are arranged in the rack body and are communicated through a through hole, a lifting testing frame is arranged in the through hole of the refrigerating box body and the heating box body, an upper sealing plate and a lower sealing plate are arranged at two ends of the lifting testing frame, the middle of the lifting testing frame is of a net-shaped structure, the upper end of the lifting testing frame is connected with a steam cylinder by a pulley through a rope, the refrigerating box body is connected with a refrigerating device arranged in the rack body through a pipeline, a heating device is arranged in the heating box body, airflow circulating paths driven by an air blower are respectively arranged in the refrigerating box body and the heating box body, and a sealing door is arranged on the rack body. According to the lifting type cold-hot impact tester, the design is scientific, the energy is saved, is environmental protection is realized, and the testing is accurate because a testing environment is close to an environment temperature; meanwhile, the service life of the cold-hot impact tester is greatly prolonged.

Description

Technical field: [0001] The invention relates to the technical field of testing equipment, in particular to a lifting type thermal shock testing machine. Background technique: [0002] The thermal shock testing machine is an energy storage type thermal shock test chamber. The main test products are used for testing current electronic components. The thermal shock testing machine can simulate the instantaneous change environment between high temperature and low temperature. In order to judge whether the reliability and stability of the product are qualified; it will provide you with the basis for predicting and improving the quality and reliability of the product, which is used to detect electronics, automobiles, rubber, plastics, aerospace technology, military technology and advanced communication equipment, etc. The resistance ability of the product under repeated cold and heat changes. At the same time, through this equipment test, the reliability of the product can be imp...

AI Technical Summary

Problems solved by technology

[0003] However, there are certain problems in the structural design of the existing thermal shock testing machine. The refrigeration and heating devices installed in the test chamber, the refrigeration device and the heating device are interchangeable and convective, so as to achieve the high and low temperature impact test of the product. To neutralize such a large amount of energy, a large amount of electricity needs to be used to produce heat and cold air. At the same time, the speed of temperature conversion is not fast enough, the test is not scientific enough, and the service life of the thermal shock test machine is also short.
