As shown in fig. 1-3, a freeze dryer box and refrigeration evaporator integrated structure comprises a box wall component 1, a baffle pipe 6, a guide pipe component, an inlet header 2, an inlet pipe 4, an outlet header 3 and an outlet pipe 5.

The flat pipe components are connected with each other to form a box wall component 1, the box wall component 1 can be used as the box wall of a freeze dryer box body to play a role in supporting and sealing, and can also play a role in refrigerating by filling a refrigerant; one end of the box wall component 1 is connected with the baffling pipe 6, and the other end is connected with the guide pipe component; the flow guide pipe assembly is formed by connecting an inlet header 2 and an outlet header 3; the baffling pipe 6 and the flow guide pipe assembly are communicated with each other through the tank wall assembly 1 to convey a refrigerant; the outer side wall of the inlet header 2 is connected with an inlet pipe 4; an inlet pipe 4 communicating with the inlet header 2, refrigerant being discharged into the inlet header 2 through the inlet pipe 4; the outer side wall of the outlet header 3 is connected with an outlet pipe 5; the outlet pipe 5 communicates with the outlet header 3, and discharges the refrigerant in the outlet header 3 into the outlet pipe 5.

A partition plate is arranged between the inlet header 2 and the outlet header 3 to prevent the refrigerant in the inlet header 2 from directly flowing into and being discharged from the outlet header 3; the flat pipe fitting is a first micro-channel flat pipe 7, and a plurality of first capillary pipelines are arranged inside the first micro-channel flat pipe 7; by the principle of heat transfer, the refrigerants in the first capillary pipelines absorb the heat transferred to the first microchannel flat tube 7 by the freeze dryer box body to refrigerate the freeze dryer box body; the flat pipe fitting is a second micro-channel flat pipe 8, and a plurality of second capillary pipelines are arranged inside the second micro-channel flat pipe 8; by the principle of heat transfer, the refrigerants in the second capillary pipelines absorb the heat transferred to the second micro-channel flat tubes 8 by the freeze dryer box body to refrigerate the freeze dryer box body; the flat pipe fitting is a third micro-channel flat pipe 9, and a plurality of third capillary pipelines are arranged inside the third micro-channel flat pipe 9; by the heat transfer principle, the refrigerants in the third capillary pipelines absorb the heat transferred to the third micro-channel flat tubes 9 by the freeze dryer box body to refrigerate the freeze dryer box body; a first electromagnetic valve is arranged in the inlet pipe 4, a second electromagnetic valve is arranged in the outlet pipe 5, and the first electromagnetic valve and the second electromagnetic valve control the circulation of refrigerant; first microchannel flat pipe 7, second microchannel flat pipe 8 and third microchannel flat pipe 9 are made by aluminium material, and aluminium has the characteristics that the quality is little, still good heat conductivity.
