PURPOSE: An environment test device is provided to help a temperature inside a chamber to reach to a test temperature by installing a new chamber for raising an air from the chamber. CONSTITUTION: In an environment test device, an environmental testing apparatus(1) comprises four chambers and a common duct(2). The four chamber independently performs a burn-in test, and the environmental testing apparatus is formed by interlinking the four burn-in test apparatus to the common duct. The chamber receives the air from the common duct in raising the temperature, and the high temperature air discharged from the chamber flows through inside the common duct. The flowed air into the chamber increases the inside temperate of the camber in temperature rising. Each chamber has a ventilation unit, and the environmental testing apparatus controls the internal environment through the air intake and discharge. |
