High-low temperature test chamber

Abstract

The invention relates to a high-low temperature test box, which comprises a casing, a working chamber, a refrigeration system, a heating wire and an electrical system. The front face of the casing is provided with an open type box door, and the working chamber, the refrigeration system, the heating wire and the electrical system are arranged in the casing. The working chamber is arranged on the rear portion of the box door, the refrigeration system is arranged on the lower portion of the working chamber, the heating wire is arranged on the rear portion of the working chamber, the outsides of the working chamber and the heating wire are wrapped with heat insulation cotton, and the electrical system is arranged on one side of the working chamber. Compared with the prior art, the high-low temperature test box can save energy consumption by 20%, and equipment can not be affected under low temperature. The high-low temperature test box can automatically control heating according to the difference of monitored temperature so as to avoid moisture condensation of an observation window and has the advantages of being transparent, heat-insulation, not prone to generate steam frosting and the like. A gluing piece type conducting film is arranged on the inner side of the high-low temperature test box, thereby conveniently observing situation in the box from the observation window at any time, being completely independent in warming, cooling and system, improving efficiency, further reducing testing cost, prolonging service life, and reducing fault rate.

Description

technical field [0001] The invention relates to a temperature detection device, in particular to a high and low temperature test box. Background technique [0002] At present, many high and low temperature test chambers use self-made heating wires, which are directly wound on the spiral porcelain rods with stainless steel wires. The temperature fluctuations are relatively large when doing high and low temperatures each time, and must be self-tuned every time, so for The operation of the equipment brings great disadvantages, and also greatly increases the cost of the test. Contents of the invention [0003] The object of the present invention is to provide a high and low temperature test box with improved efficiency, lower testing cost and lower failure rate in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A high and low temperature test cham...
