Rapid temperature-changeable test box

Abstract

The invention discloses a rapid temperature-changeable test box which comprises a device main body, a cabinet door and a casing. The left side of cold-rolled steel is provided with heat-insulating cotton, the heat-insulating cotton is closely fitted to the cold-rolled steel, an air switch is arranged on the left side of the lower part of the interior of the casing, the air switch is fixedly connected with the casing, the bottom of the device main body is provided with a base, the base is fixedly connected with the device main body, a see-through window is arranged in the middle of the cabinetdoor, the see-through window is in embedded connection with the cabinet door, the see-through window is made of two layers of high-light-transmissive tempered glass, and the air in the middle of the two layers of glass plates is pumped away to form a vacuum environment, so that temperature propagation medium does not exist, for facilitating observing situation in the cabinet by a user, while not causing temperature change in the device main body. Because temperature propagation medium does not exist, no water mist occurs on the glass of the see-through window of a low temperature cabinet, which makes the observation of the user more convenient, is suitable for the use of the rapid temperature-changeable test box. The rapid temperature-changeable test box has broad application prospects inthe future.

Description

technical field [0001] The invention relates to the technical field of test chambers, in particular to a rapid temperature change test chamber. Background technique [0002] The test chamber is the general term for products in the environmental test industry. It simulates the natural climate environment within the effective space. The types of tests include: high and low temperature test chambers, xenon lamp aging test chambers, ultraviolet aging test chambers, box-type rain Rust grease, drip device. [0003] However, the existing test chamber has only one detection cabinet, which cannot perform low temperature and high temperature detection at the same time. It can only be detected one by one, which makes the work efficiency low. The time to set the temperature is long, and the energy consumption is large. At the same time, in order to pursue the heat preservation effect, the cabinet is sealed, so that the heat generated by the circuit components in the test box is slow to...
