Embodiment Construction
[0029] Below in conjunction with the embodiment, the technical scheme of the present invention is described in more detail:
[0030] like figure 1 , 2 As shown, the present invention includes a cold fluid inlet and outlet, a hot fluid inlet and outlet, and a heat exchange core 2. The heat exchange core 2 includes a cold side plate 10 and a hot side plate 11 made of titanium or titanium alloy materials. The cold side plate 10 is etched with a plurality of juxtaposed cold side Zig-Zag channels 17 with a D-shaped cross section for the cooling fluid to pass through, and the hot side plate 11 is etched with a plurality of juxtaposed and provided The hot fluid passes through the hot side Zig-Zag channel 19 with a D-shaped cross-section. The cold side plate 10 and the hot side plate 11 are arranged in parallel and alternately overlapped and connected together by diffusion welding technology. The thickness of the hot side plate 11 is different, the cross-sectional area of the cold...
