High-low temperature impact test box

Abstract

The invention relates to the technical field of sample temperature impact test instruments, in particular to a high-low temperature impact test box which comprises a high temperature box body, a low temperature box body, an electrical cabinet, an electrical system, a refrigeration system and a heating system, wherein the heating system is arranged inside the high temperature box body, the refrigeration system is arranged inside the low temperature box body, and both the heating system and the refrigeration system are in wired connection with the electrical system. The high-low temperature impact test box is characterized in that a high temperature slot air-conditioning system is arranged inside the high temperature box body, a low-temperature slot circulating system is arranged inside the low-temperature box body, both the high temperature slot air-conditioning system and the low-temperature slot circulating system are in wired connection with the electrical system, and basket transmission systems capable of moving up and down are arranged inside the high temperature box body and the low-temperature box body respectively. According to the invention, since the upper and lower boxes adopt different media, the high-temperature box adopts air, and the low-temperature box adopts water, the specific volume of water is very large, and during impacting, a test piece is enabled to reach a low temperature instantaneously. Therefore, the testing is enabled to be rigorous and the testing requirements of special material can be met.

Description

[technical field] [0001] The invention relates to the technical field of sample temperature shock test instruments, in particular to a high and low temperature shock test chamber. [Background technique] [0002] At present, the two-box temperature shock test chamber has a very short high and low temperature conversion time and severe temperature changes, so it can quickly detect the temperature resistance of the test product under the condition of repeated and rapid temperature changes of the material, but currently on the market The mainstream products mainly have the following problems: [0003] 1. The upper and lower boxes are basically subjected to the high and low temperature impact of the same medium, rarely involving two different media, which cannot meet the special test requirements; [0004] 2. It is basically an impact mode, and the upper and lower boxes cannot be tested separately for high and low temperature, and the utilization rate of the product is not high;...

AI Technical Summary

Problems solved by technology

[0003] 1. The upper and lower boxes are basically subjected to the high and low temperature impact of the same medium, rarely involving two different media, which cannot meet the special test requirements;

[0004] 2. It is basically an impact mode, and the upper and lower boxes cannot be tested separately for high and low temperature, and the utilization rate of the product is not high;

[0005] 3. The temperature control is generally controlled by the tuyere, not the temperature of the product surface, and the product temperature cannot reach the set value quickly;

[0006] 4. The wind speed is constant, and different wind speeds cannot be set according to different products;

[0007] 5. The degree of automation is not high, centralized remote monitoring cannot be performed, and the preservation of test history curves is not ideal
