Specific embodiment
As shown in Figs. 1-2, the insulating box 1 including filling cooling water, the insulating box 1 is interior to be equipped with several groups to the utility model
Sample water-circulating pipe 2, the insulating box 1 are equipped with water inlet end and water outlet, and the water inlet end and water outlet pass sequentially through circulating pump
Composition cooling water circulation loop is connected with condenser；Heating tube 3 is equipped in the insulating box 1, the heating tube 3 passes through supporting rack
4 are uniformly surrounded on the side wall of the insulating box 1.
In insulating box 1 during heating cooling water, cooling water can have differences in different height, and heating tube 3 is uniformly surrounded on perseverance
The side wall of incubator 1 can reduce the temperature difference of different height cooling water, further improve the reliability and stability of detection data；Add
Heat pipe 3 is uniformly surrounded on the side wall of insulating box 1, and spiralling mode can be used and wind, i.e., the import of heating tube 3 is in insulating box
1 bottom, the side wall ring around insulating box 1 is around the top position risen to close to insulating box 1；It can also be used along insulating box 1
The heating tube 3 of wall horizontal direction winding, it is uniformly distributed to arrange in the vertical direction equipped with several sections, it often saves heating tube 3 and is designed with import
