Embodiment Construction
[0034] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.
[0035] Please refer to Figure 1 to Figure 6 As shown, the fin-enhanced heat exchange multi-split infrared suppressor of the present invention includes a gas collection chamber 1, a multi-split nozzle 2, a mixing tube 3, a heat shield 4, and a heat exchange enhanced chamber 5.
[0036]The air-collecting chamber 3 is a cavity formed by a firewall 6, a baffle plate 8, and a side wall. The enhanced heat exchange cavity 5 is a cavity composed of skins on both sides and bottom. At the center of the plane where the firewall 6 is located, there are multiple air inlets 10 for the diverging nozzles, and the air inlets 10 for the multi-firing nozzles are annular. There are cold air inlets 7 on the upper and lower walls of the air collection chamber 1; the baffle plate 8 is the interface between the air collection chamber 1 and the enhanced heat exchange chamber...
