High-and-low-temperature alternating humidity and heat test chamber

Abstract

The invention discloses a high-and-low-temperature alternating humidity and heat test chamber. The high-and-low-temperature alternating humidity and heat test chamber comprises a box body, a box doorrotatably arranged at the opening side of the box body, and a heating mechanism, a refrigeration mechanism and a humidifying mechanism which are arranged in the box body, wherein the box body comprises an inner plate and an outer plate arranged at the outer side of the inner plate. By adoption of a technical scheme of the invention, the high-and-low-temperature alternating humidity and heat test chamber can be applicable to an ultralow-temperature environment with a temperature of lower than minus 100 DEG C and an ultrahigh-temperature environment with a temperature of 200 DEG C or higher, hasgood heat-preserving performance, is stable and reliable, does not generate large deformation, and guarantees stability of a box body structure and airtightness of the box body; when a humidity testis required, a humidity sensor located in the inner chamber of the box body can monitor the humidity of the inner chamber of the box body in real time; when an ultralow-temperature or ultrahigh-temperature test is about to be carried out, the humidity sensor is no longer located in the inner chamber of the box body and is effectively protected and avoided from being damaged; thus, stable operationof the high-and-low-temperature alternating humidity and heat test chamber is guaranteed.

Description

technical field [0001] The invention relates to the technical field of high and low temperature alternating damp heat test, in particular to a high and low temperature alternating damp heat test chamber. Background technique [0002] The high and low temperature alternating humidity test chamber is the necessary testing equipment for aviation, automobile, household appliances, scientific research and other fields. It is used to test and determine the temperature of electrical, electronic and other products and materials for high temperature, low temperature, alternating humidity or constant test. Parameters and performance after environmental changes. [0003] The existing high and low temperature alternating damp heat test chamber can simulate the ambient temperature of tens of degrees below zero to more than one hundred degrees above zero, but some products used in certain fields need the high and low temperature alternating damp heat test chamber to simulate more than one...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the technical problem that the box body is prone to deformation when the ambient temperature changes greatly, and the box body insulation structure and humidity sensor are not suitable for the ultra-low temperature environment of more than one hundred degrees below zero, the invention provides a high and low temperature alternating damp heat test box
