The utility model discloses a peltier refrigerating system, this system include peltier 12, cooling system, temperature control system and hot protector. Wherein the cold end of the peltier 12 is used to provide a cooling function. The heat dissipation system is used for taking away heat of the hot end of the Peltier 12, so that the hot end of the Peltier 12 is dissipated in time, and stable operation of the Peltier 12 is guaranteed. The temperature control system controls the start and stop of the Peltier 12 according to the temperature of the refrigerated equipment. The specific control principle is as follows: when the temperature of the refrigerated equipment exceeds a set temperature value, the temperature control system controls the Peltier 12 to be started; when the temperature of the refrigerated equipment is lower than the set temperature value, the temperature control system controls the Peltier 12 to stop. Therefore, the Peltier 12 can be started and stopped regularly, and the efficient operation is realized. The thermal protector is arranged in series with the peltier element 12. When the working environment temperature of the peltier element 12 exceeds the protection temperature of the thermal protector, the thermal protector will open, forcing the peltier element 12 to stop working. In this way, damage to the peltier element 12 due to excessive temperatures can be avoided.
Further, the thermal protector is connected with the peltier part 12 by welding, and a heat-shrinkable sleeve 2 is sleeved on the welding position, and the heat-shrinkable sleeve 2 is used for protecting the welding position.
Furthermore, in order to facilitate the connection of the peltier element 12 to the power supply, the peltier element 12 may be connected to the plug 1, and the connection between the peltier element 12 and the power supply may be achieved by directly inserting the plug 1 into the power supply.
Further, the cold end of the peltier element 12 is attached to the reagent disk 4 so that the reagent disk 4 is at a set temperature. In this embodiment, heat-insulating cotton is attached to both the bottom surface and the side surface of the reagent disk 4. The heat preservation cotton adhered to the bottom of the reagent tray 4 is bottom heat preservation cotton 5, and the heat preservation cotton adhered to the side face of the reagent tray 4 is side heat preservation cotton 6. The heat preservation cotton can reduce the heat transfer of reagent dish 4 and external environment, plays the heat preservation effect to reagent dish 4.
In addition, the temperature sensor 7 in the temperature control system is installed on the outer wall of the reagent disk 4. The outer wall of the reagent disk 4 is provided with a slot hole, and the temperature sensor 7 is placed in the slot hole.
