Cold and hot impact simulation test box and rapid cooling and heating method thereof

Abstract

The invention relates to the technical field of test equipment, and particularly relates to a cold and hot impact simulation test box and a rapid cooling and heating method thereof. The cold and hot impact simulation test box comprises a test box main body. A simulation test box, a cooling water tank and two liquid nitrogen tanks are arranged in the test box main body, and the two liquid nitrogen tanks are arranged on the two sides of the simulation test box correspondingly; the cooling water tank is connected with the simulation test box; a heating copper wire is arranged on the side, close to the inner wall of the simulation test box, in the simulation test box composition plate, ventilation and heat dissipation mechanisms are arranged on the upper end surface and the lower end surface of the simulation test box, and a clamping mechanism is arranged in the simulation test box; and heat dissipation holes are formed in the upper portion of the test box main body, a moving mechanism is arranged on the lower end surface of the test box main body, and an electric control box is arranged on the side surface of the test box main body. The rapid cooling and heating effect of a traditional cold and hot impact test box can be improved, the part detection efficiency of the cold and hot impact test box is improved, and the interior of the cold and hot impact test box can be rapidly cooled and refrigerated.

Description

technical field [0001] The invention relates to a test box, in particular to a cold and heat shock simulation test box and a rapid cooling and heating method thereof, belonging to the technical field of testing equipment. Background technique [0002] The thermal shock simulation test box is a necessary test equipment for metal, plastic, rubber, electronics and other material industries. It is used to test the material structure or composite material. Detect chemical changes or physical damage caused by thermal expansion and contraction of the sample in the shortest time; [0003] However, the current cold and thermal shock simulation test box is relatively slow in testing parts from high temperature to low temperature, and cannot quickly perform cold and thermal shock treatment of parts, thereby reducing the testing efficiency of parts in the cold and thermal shock simulation test box. [0004] Therefore, there is an urgent need to improve the thermal shock simulation test...
