[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, the column temperature box structure of this embodiment includes a box body 100, a heating and cooling component arranged in the box body 100, and the heating and cooling component includes a heat sink 110 and a heat sink 120 arranged in the box body 100, and a Peltier 161 is also arranged between the heat sink 110 and the heat sink 120, wherein the heat sink 110 and the heat sink 120 are arranged back to back. And the heat sink 1 is located in the sealed cavity, and the heat sink 2 is located in the open cavity. At present, during the use of the column temperature box structure, there are usually different needs for temperature control, heating and cooling, considering that the temperature control, heating and cooling have poor stability. In this embodiment, the heating and cooling of the heat sink 110 and the cooling and heating of the heat sink 2 120 on both sides of the Peltier 161 are controlled to achieve control of the heating and cooling of the column box structure.

[0024] A heat insulation board is arranged in the box body. Here, the heat insulation board is fixed in the sealed cavity 150. A heat sink 110 is fixedly arranged at one end of the heat insulation board, and a heat sink 120 is fixedly arranged at the other end.

[0025] The partition 162 in the box 100 separates the sealed cavity 150 and the open cavity 160. The heat sink 1 110 is located in the sealed cavity 150, and the heat sink 2 120 is located in the open cavity 160. A circulating airflow is formed in the box to ensure uniform temperature. When the heat sink 1 110 is located in the sealed cavity 150 for heating, the heat sink 2 120 is located in the open cavity 160 for cooling; when the heat sink 1 110 is located in the sealed cavity 150 for cooling, the heat sink 2 120 is located in the open cavity 160 for heating.

[0026] High temperature resistant heat preservation cotton 180 is arranged around the sealed cavity 150 to prevent convection with the ambient air and play a role in sealing and heat preservation. A temperature control probe 140 is arranged in the sealed cavity 150. The temperature control probe 140 can accurately detect the heating and cooling effect in the sealed cavity 150, and the temperature in the sealed cavity 150 reaches stability.

[0027] A circuit board 170 is disposed in the open cavity 160, and the circuit board 170 is signal-connected to the Peltier 161. The circuit board 170 can energize the Peltier 161 to control the heat sink 1 110 to cool while the heat sink 2 120 heats up. The circuit board 170 can energize the Peltier 161 to control the heat sink 1 110 to heat while the heat sink 2 120 cools.

[0028] The first heat sink 110 and the second heat sink 120 are controlled for cooling and heating by a Peltier 161 electrically controlled by a circuit board 170. A mounting groove 163 is provided on the partition 162, and the mounting groove 163 is suitable for placing the Peltier 161. The partition 162 separates the sealed cavity 150 from the open cavity 160.

[0029] In order to improve the efficiency of heating and cooling effect in the box 100, a fan 130 is provided on the heat sink 110, and the blowing direction of the fan 130 is consistent with the heating direction of the heat sink 110, and the sealed cavity 150 can be quickly heated and cooled by the blowing of the fan 130. Here, the heating direction is from one end of the sealed cavity 150 to the other end of the sealed cavity 150, that is, the heat sink 110 is fixed on the insulation board, and the insulation board is fixed at one end of the sealed cavity 150. The heating direction is from one end of the sealed cavity 150 with the insulation board fixed to the other end of the sealed cavity 150, and the fan blows the hot air or cold air on the heat sink 110 to the end of the sealed cavity 150 away from the heat sink 110, thereby accelerating the air flow in the sealed cavity 150.

[0030] A frame 190 is disposed on the heat sink 110 , and a threaded hole 191 is opened on the frame 190 , wherein the fan 130 can be fixedly disposed on the frame 190 .
