Embodiment 1
[0028] Embodiment 1: refer to image 3 As shown, the heat exchange surface 3 of the heat exchange orifice plate 2 is a flat structure, and a plurality of microholes or small hole flow channels 4 are arranged side by side in the heat exchange orifice plate 2, and the cross section of the microhole or small hole flow channels 4 is circular Structure; the heat exchange surface 3 itself is the maintenance structure of the micropore or small hole flow channel 4.
Embodiment 2
[0029] Embodiment 2, with reference to Figure 4 As shown, the heat exchange surface 3 of the heat exchange orifice plate 2 is a flat structure, and a plurality of micropores or small hole flow channels 4 are arranged side by side in the heat exchange orifice plate 2, and the cross section of the micropore or small hole flow channels 4 is oval Structure; the heat exchange surface 3 itself is the maintenance structure of the micropore or small hole flow channel 4.
Embodiment 3
[0030] Embodiment 3, with reference to Figure 5 As shown, a plurality of micropores or small hole flow channels 4 are arranged side by side in the heat exchange orifice plate 2, and the cross section of the micropore or small hole flow channels 4 is an elliptical structure. The shape of the hole or small hole flow channel 4 is wavy; the heat exchange surface 3 itself is the maintenance structure of the micro hole or small hole flow channel 4 .
[0031] The working principle of the present invention is as follows:
[0032] 1. Heat absorption process from high temperature environment: the low temperature fluid in the collecting and distributing pipe 1 is distributed to the micropore or small hole flow channel 4 of the heat exchange orifice plate 2, and the heat exchange orifice plate through which the thinned low temperature liquid passes The overall heat exchange surface 3 of 2 forms a low-temperature heat exchange surface, which absorbs ambient heat from the high temperature...
