Abstract
The utility model belongs to the field of universal testing machines, and particularly relates to a temperature control test box for ultralow-temperature mechanical property detection, which comprises a box main body, a door body hinged with the box main body, and a cover body in sealing fit with the box main body and the door body, the box main body, the door body and the cover body are encircled to form an ultralow-temperature test space; a liquid storage tank is arranged on the box body, and a gas backflow tank is arranged on the door body; the bottom of the box main body is also provided with a wind disc which is respectively connected with the liquid storage tank and the gas backflow tank; and an electric heating sheet is arranged in the liquid storage tank. The temperature in the box body is regulated and controlled by controlling the temperature rise of the liquid nitrogen and regulating the volatilization rate of the liquid nitrogen, and meanwhile, the volatilized liquid nitrogen flows to the ultralow-temperature test space through the air disc, overflows to the gas backflow groove and flows back to the air disc through the gas backflow groove to flow to the ultralow-temperature test space, so that low-temperature gas circularly flows in the box body; and the uniformity of temperature distribution in the detection space is improved.
