As shown in fig. 1 and 2, the heat exchange device mainly comprises a heat exchange plate 1 in the middle, bus plates 2 symmetrically distributed on the upper side and the lower side of the heat exchange plate 1, and two drainage connecting pipes 3 respectively communicated with the bus plates 2 on the two sides; the two drainage connection pipes 3 respectively lead the liquid medium for heat transfer into/out of the busbar plate 2; four temperature sensing probes are symmetrically arranged on the left side and the right side of the heat exchange plate 1 and are used for sensing the overall temperature condition of the heat exchange plate.

As shown in fig. 3-7, the heat exchange plate 1 is internally provided with a plurality of parallel heat exchange channels 11, the bus plate 2 is internally provided with bus channels 21 perpendicular to the heat exchange channels 11, and a first guide channel 22 and a second guide channel 23 which are consistent with the heat exchange channels 11 in number, and the drainage connecting pipes 3 are coaxially communicated with the bus channels 21; wherein the first guide channel 22 is directly coaxially butted with the heat exchange channel 11, and the second guide channel 23 is vertically butted with the first guide channel 22 and the converging channel 21, so that the heat exchange channel 11 is communicated with the converging channels 21 at two sides; in addition, each second guide channel 23 is provided with an adjusting screw 24 screwed from the outside, which can control the connection of the second guide channel 23 with the first guide channel 22, and the screw end of which extends into the second guide channel 23 and the nut end of which is exposed outside the bus plate 2.
