[0030] The cooling plate 21 is connected to the micro-channel reactor body 1 by welding, and the cooling plate 21 is connected to the micro-channel reactor body 1 by welding, so that the cooling plate 21 can be sealingly connected to the micro-channel reactor body 1 to prevent leakage of the cooling liquid.

[0031] In this embodiment, the cooling liquid in the liquid storage tank 22 is pumped into the cooling liquid flow channels 211 of the two groups of cooling plates 21 by the pump body 23, and the cooling liquid is cooled by heat exchange with the surface of the reactor body, so that the upper and lower ends of the micro-channel reactor body 1 can be cooled at the same time. Compared with the current cooling effect, the cooling effect is more uniform, and the experimental data is more accurate.

[0032] As shown in Figure 2 , the cooling plate 21 is provided with a liquid inlet 212 and a liquid outlet 213 on one side, which are connected to the cooling liquid flow channels 211.
