Abstract

A structurally segmented VOC release chamber having an electronic cooling pad for temperature control, comprising at least two interconnected chamber segments (1). Chamber compartments are provided in the chamber segments (1). Externally connecting flanges (11) are fixedly provided at the end parts of the chamber segments (1). One externally connecting flange (11) and the other externally connecting flange (11) correspondingly connected thereto employ a mounting bolt to implement the connection. The mounting bolt comprises a first bolt (111) arranged below the externally connecting flanges. A through hole (2) used for mounting/unmounting the first bolt (111) is provided at the bottom of the chamber compartments. A sealing cover (3) used for sealing the through hole (2) is removably provided on the through hole (2). Obviated is the need to lift the release chamber to complete the mounting/unmounting of the connecting bolt below the connecting flanges, thus greatly saving input costs of an early-stage infrastructure for a large-sized release chamber.
