The invention discloses a constant-temperature power distribution cabinet, which comprises a cabinet body with an opening in the front end and cabinet doors, wherein the cabinet doors are connected to the front end of the cabinet body through hinges; a slope plate which is high in the middle part and low in two sides is formed at the bottom part in the cabinet body; a stepper motor is arranged at the upper part, at the middle position of the slope plate, of the lower part of a rear cabinet plate, at the rear side of the cabinet body, in the cabinet body; an output shaft of the stepper motor is connected with a refrigeration piece assembly which is horizontally arranged along the frontward-backward direction of the cabinet body; a front baffle plate is arranged at the lower part of the front side of the cabinet body; a first flow guide plate is fixedly connected to the left upper part of the refrigeration piece assembly in the cabinet body; a baffle plate is fixedly connected to the right side of the refrigeration piece assembly in the cabinet body; an upper air inlet is formed in the left side, between the first flow guide plate and the second flow guide plate, of the cabinet body; an upper fan is arranged in the upper air inlet; the outer wall on the left side of the cabinet body is connected with an upper air inlet plate above the upper air inlet; and exhaust openings are formed in the left side and the right side of the upper part of the cabinet body. The constant-temperature power distribution cabinet is simple and compact in structure and suitable for various complicated working environments.

The invention relates to a storage method and device for epitaxial wafers. The storage device for the epitaxial wafer includes a storage box, the storage box includes a moisture-proof cover plate and a placement body, the outer surface of the placement body is fixedly connected with a bottom edge plate at a position close to the bottom, and the bottom edge plate is opposite to the placement body Symmetrically arranged, the bottom is provided with a through hole along the outer surface of the board; the main body is placed, the upper end of the main body is open, and an upper card box is fixedly connected to the opening, and an access window is opened on the outer surface of the main body. The inner surface of the placement main body is connected with an access window cover, the access window cover closes the access window, and at least one group of placement compartments is arranged inside the placement main body, and the number of the placement compartments is the same as that of the access window. The quantity is corresponding; the placement compartment is provided with a flat plate, and the epitaxial wafer is placed on the surface of the flat plate; the storage method and device of the epitaxial wafer are ingenious in design, flexible in use, and convenient for storage and use of the epitaxial wafer.

The invention relates to a laboratory for the state control of air positive and negative pressure in ship cabins, comprising three functional partitions and five systems; the five systems are respectively an air supply system, an air exhaust system, a return air system, Control system and differential pressure monitoring system. The three functional divisions are control room, equipment room and air experiment area. The air experiment area is the area for controlling the state of indoor air positive and negative pressure. It is divided into four sub-physical divisions, namely: Corridor areas, buffer zones, potentially contaminated areas and core areas. The invention establishes a laboratory for the control of the air positive pressure and negative pressure state of the ship cabin. Through the experiment of the air positive pressure and negative pressure state control carried out in the laboratory, the empirical parameters are obtained, which can be used as a positive pressure protection room and a Data reference for the construction of the negative pressure isolation room; a return air system is set up in the air test area, so that the directional airflow between the sub-physical sub-divisions flows passively under the action of the pressure difference gradient, which simplifies the complexity of the system and improves the operating efficiency of the system.
