Embodiment Construction
[0024] The specific structure and working principle of the device of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] Such as figure 1 As shown, a microreactor of the present invention that couples the microreaction function and the temperature field detection function of the reaction area is composed of an intelligent temperature sensor array 4, a printed circuit board 6, a microchannel chip layer 7, an upper heat exchange layer 2 and a lower heat exchange layer. The layer 9 consists of two symmetrically arranged heat exchange layers and two symmetrically arranged sealing layers of the upper sealing layer 3 and the lower sealing layer 8, and is assembled as a whole by several bolts 1 and corresponding nuts 10. Since the smart temperature sensor array 4 is inserted into the socket 5 in the middle of the side of the microchannel chip layer 7, the figure 1 is not displayed in .
