Low-temperature test tube box for placing samples for field experiments

Abstract

The utility model discloses a low-temperature test tube box for placing samples for field experiments, which relates to the field of low-temperature sampling devices and comprises a box body, a box cover, a low-temperature test tube placing component, a condensation circulating pump, a fan, a storage battery and a control panel, the box cover is hinged to the top of the box body, and the control panel is embedded in the front side of the box body. A containing cavity with an opening in one end is formed in the box body, the low-temperature test tube containing assembly is fixedly connected into the containing cavity through bolts, the storage battery and the condensation circulating pump are both installed at the bottom of a heat dissipation cavity, the condensation circulating pump communicates with an inner cavity of the low-temperature test tube containing assembly through a pipeline, and heat dissipation holes are formed in the lower middle portion of the periphery of the box body. The heat dissipation holes are communicated with the heat dissipation cavity, and at least two fans are symmetrically installed on the inner wall of the heat dissipation cavity. According to the test tube storage device, long-acting low-temperature storage of test tube samples is realized, meanwhile, full contact between test tubes and a cooling medium is ensured, and the storage quality is improved.
