The present invention relates to a pressure chamber, which comprises: a housing (100) having a pressurizing space formed therein; a door (300) for selectively shielding one side of the housing (100); a pressure port (250) provided on one side of the housing (100) to connect a pressure control device to the pressurizing space; a temperature control port (500) provided on one side of the housing (100) to connect a temperature control device to the pressurizing space; and an air circulation unit provided on one side of the housing (100), and maintaining the temperature of the pressurizing space. Each edge of the housing (100) is formed with round portions (105) in a round shape, first and second housings are welded to each other so as to constitute one housing (100), and the welding of the first and second housings is performed on a straight portion formed between the round portions (105). According to the present invention, the housing (100), which constitutes the pressure chamber, consists of two bodies, so a welding part (P) is reduced down to two parts, thereby reducing the total number of components and manufacturing processes of the pressure chamber. |
