Description

Technical Field

[0001] The utility model relates to the technical field of thermogravimetric analyzers, in particular to a cooling device applied to thermogravimetric analyzers. Background Art

[0002] Thermogravimetric analyzer is an instrument that uses thermogravimetric method to detect the relationship between the temperature and mass change of a substance. It can measure the relationship between the mass of a substance and the temperature (or time) under program temperature control. When using a thermogravimetric analyzer, it is sometimes necessary to quickly cool down the heating unit furnace in order to end the test or start a new round of tests. Existing thermogravimetric analyzers generally use coils to cool down the heating furnace. Since the inner side of the coil is only in line contact with the heating furnace, the contact area is small, which leads to slow cooling speed and low efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a cooling device applied to a thermogravimetric analyzer to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling device applied to a thermogravimetric analyzer, comprising a heating furnace, a quick-connect connector, a refrigeration box cover, an outer sleeve and a refrigeration box, wherein the quick-connect connectors are respectively arranged at the upper and lower ends of the refrigeration box, the quick-connect connectors are connected to the refrigeration box, the outer sleeve is sleeved on the outer wall of the refrigeration box, the refrigeration box is sleeved on the heating furnace, and a refrigeration box cover is provided on the top of the refrigeration box.

[0005] Preferably, a sealing ring is provided between the refrigeration box and the refrigeration box cover.

[0006] Preferably, thermal insulation cotton is provided between the refrigeration box and the outer sleeve.

[0007] Preferably, thermally conductive silicone grease is provided between the refrigeration box and the heating furnace.

[0008] Compared with the prior art, the utility model has the beneficial effect that the utility model can quickly cool down the thermogravimetric analyzer by arranging a refrigeration box sleeve on the heating furnace, so that the thermogravimetric analyzer can quickly carry out the next round of testing, thereby improving work efficiency.
