Abstract

The invention discloses a heat flow type differential scanning calorimeter, and relates to the technical field of thermal analysis instruments.The heat flow type differential scanning calorimeter comprises a calorimeter body and a heat dissipation mechanism, the heat dissipation mechanism is fixedly connected to the left end of the calorimeter body, the side face of the calorimeter body is fixedly connected with the heat dissipation mechanism, and the top of a heating bin is movably connected with a heating bin door; a locking mechanism is arranged at the front end of the heating bin door, and a fixing mechanism is movably connected to the bottom end of the calorimeter body. Heat in the instrument can be absorbed through the heat dissipation fins, hot air in the instrument can be exhausted from the exhaust port through work of the heat dissipation fan, air exchange can be conducted on the interior of the instrument through the air exchange port, and the heat dissipation effect of the instrument is improved. According to the calorimeter, the problem that when an existing calorimeter is used, heat in the heating bin affects use of the calorimeter is solved, use of the calorimeter is facilitated, faults of the calorimeter are avoided, and the service life of the calorimeter is prolonged.

Description

technical field [0001] The invention relates to the technical field of thermal analysis instruments, in particular to a heat flow differential scanning calorimeter. Background technique [0002] Differential scanning calorimeter measures the relationship between temperature and heat flow related to the internal thermal transition of materials. Crystallization, phase transitions, melting, crystallization, product stability, curing / crosslinking, oxidation induction periods, etc., are all areas of study with differential scanning calorimetry. [0003] There are following problems at prior art: [0004] 1. When the existing heat flow type differential scanning calorimeter is used, the heat in the heating chamber is often dissipated to the inside of the calorimeter, so that the internal temperature of the calorimeter is too high, which affects the performance of the calorimeter. use, it is easy to cause the failure of the calorimeter; [0005] 2. When the existing heat flow ty...
