The fins 33 enhance the heat exchange effect, allowing the user to adjust the temperature.
[0029] like Figure 2 , 3 As shown, the heat exchanger includes a storage tank 20, which is installed on top of the storage tank 11.

These support feet provide stable support for the equipment, allowing users to place the equipment stably in various environments and improving its placement stability.
[0031] The specific usage and function of this embodiment are as follows:
[0032] In use, the user first places the sample into the storage box 11, and then sets the desired temperature via the controller 29. The cooler 24 or heater 25 operates as needed, heating or cooling the heat exchange fluid, transferring the temperature to the conductive fluid in the second heat exchange tube 21, and then to the conductive fluid in the first heat exchange tube 32 via the booster pump 23. The fan 15 starts, drawing in outside air, which exchanges heat with the heat exchanger in the heat exchange chamber before entering the storage box 11. The ambient temperature sensor 34 and the pipe temperature sensor 35 monitor the temperature to ensure a constant temperature environment within the storage box 11. The generated condensate flows into the collection tank 19 through the outlet of the drip tray 16. Throughout the process, the sealing door 28 and sealing ring 36 ensure a tight seal, and the support feet ensure stable placement of the equipment.
