Device for high and low temperature shock tests

Abstract

The invention provides a device for high and low temperature shock tests. The device comprises a shell and partition plates arranged in the shell. The shell is divided by the partition plates into a first cavity, a second cavity and a third cavity, wherein the first cavity is used for conducting a high-temperature test on a product to be tested, the second cavity is used for conducting a low-temperature test on a product to be tested, and the third cavity is used for stopping heat exchange between the first cavity and the second cavity. By the adoption of the technical scheme, rapid testing of the product to be tested is achieved, the investment cost can be reduced, and the electricity consumption of a test device can be reduced.

Description

technical field [0001] The invention relates to the technical field of product testing, in particular to a device for high and low temperature impact testing. Background technique [0002] In the process of product performance testing, in order to verify the reliability of the product, many products have to withstand severe high and low temperature shocks in the range of -50 to +70 degrees, reciprocating 10 times or more. [0003] The traditional test room is a single room. In order to complete a high and low temperature impact test, it needs to be equipped with powerful refrigeration and heating equipment, which not only requires a large investment, but also consumes a lot of power and high operating costs. Long, the cycle of the test is also very long, which is not conducive to quickly complete the test and detection. [0004] Specifically, such as figure 1 As shown, the traditional laboratory is a room in which refrigeration equipment 1' and heating equipment 2' are ins...

Problems solved by technology

[0003] The traditional test room is a single room. In order to complete a high and low temperature impact test, it needs to be equipped with powerful refrigeration and heating equipment, which not only requires a large investment, but also consumes a lot of power and high operating costs. Long, the cycle of the test is also very long, which is not conducive to the rapid completion of the test and detection

[0004] Specifically, such as figure 1 As shown, the traditional laboratory is a room in which refrigeration equipment 1' and heating equipment 2' are installed. Since the reciprocating test of high temperature → low temperature → high temperature is repeated at the same time, in order to change the temperature quickly, it is often necessary to equip high-power refrigeration and heating. Units, capital and operating costs are high, and, due to the long time required to heat up and cool down, it takes several weeks for a test
