换热箱体40带有进气口和出气口，换热箱体40的进气口与燃烧箱体的出气口33连通，换热箱体40的出气口可通过导流管体与大气或者其他设备导通。换热箱体40内设有可与燃烧箱体30排出的热气流进行换热的冷源，该冷源可以为冷凝管43、或者为外界导入的冷空气等等。换热箱体40同样采用金属材料制成，例如铝合金材料、合金钢材料等等，采用金属材料制成的换热箱体40，具有导热性能好、耐磨损等优点。当然根据设计的需要也可以采用其他的无机材料制成，其所具备的效果与上文内容一致，在此不在一一赘述。
在燃烧箱体的出气口33与换热箱体40的进气口的连接处设置有冷却组件，冷却组件在换热箱体40停止工作时，即冷凝管43、或者冷空气停止工作时，对换热箱体40内的高温气流进行冷却。以保证燃烧箱体30排出的热气流达到预设的排放条件，保护换热箱体40，避免换热箱体40出现损坏。
采用上述技术方案，通过设置在换热箱体40停止工作时对换热箱体40内的热气流继续进行冷却时冷却组件，避免换热箱体40停止工作后，因其内部的温度持续升高而导致的换热箱体40损坏。同时也保证燃烧箱体30排出的热气流的温度降至预设温度后再进行排放，提高了设备工作的安全性。
在本申请的一实施例中，所述冷却组件包括可吹出冷空气的空气泵（图中未示出）、和可将空气泵（图中未示出）吹出的冷空气引流至换热箱内与换热箱内的热空气进行换热的第一吹气管10。
具体的，冷却组件包括空气泵（图中未示出）和第一吹气管10。
空气泵（图中未示出）采用现有技术中常用的气动式真空泵，采用气动式真空泵具有体积小、重量轻、噪音低等优点。
第一吹气管10采用金属材料制成，例如铝合金材料、采用铝合金材料制成的第一吹气管10具有支撑能力强、耐磨损、工作稳定等优点。
第一吹气管10的一端连接在空气泵（图中未示出）的出气口、另一端连接在换热箱体40的进气口处用于将空气泵（图中未示出）吹出的冷空气导流至换热箱体40内部。
本申请中的换热箱体40采用水冷式换热箱体40，水冷式换热箱体40内设有电磁阀门，该电磁阀门可用于打开或关闭水冷式换热箱体40内的循环管道，同时也可以监测水冷式换热箱体40循环管道内的水流速度，当电磁阀检测到水冷式换热箱体40内的循环管道水流速度小于预设阈值时，即表示水冷式换热箱体40停止工作，此时电磁阀门将该信号通过工控机（图中未示出）发送给空气泵（图中未示出），此时空气泵（图中未示出）开始工作，向换热箱体40内泵入冷空气，对换热箱体40内的热气流进行降温处理。
采用上述技术方案，结构简单，便于实施。
在本申请的一实施例中，所述空气泵（图中未示出）上还连接有可将空气泵（图中未示出）吹出的冷空气部分引流至换热箱体40的出气口处以对换热箱体40排出的热气流进行降温的至少一个第二吹气管20体。
具体的，空气泵（图中未示出）上还连接有可将空气泵（图中未示出）吹出的冷空气部分引流至换热箱体40出气口处的至少一个第二吹气管20体，第二吹气管20体采用金属材料制成，其与第一吹气管10体所采用的材料相同，具有相同的技术效果，在此不再一一赘述。第二吹气管20体的数量为两个，两个吹气管体的出气口均匀的分布在换热箱体40的出气口的边缘。采用均匀分布的方式设置，可使得冷空气与换热箱体40排出的热气流均匀换热，换热效果更佳。
当然可以想到的是，第二吹气管20也可以连接于单独的空气泵（图中未示出），采用单独的空气泵（图中未示出）向第二吹气管20体吹入冷空气，控制简单，便于冷空气气量的调节。
采用上述技术方案，通过第二吹气管20对换热箱体40排出的热气流再次进行冷却降温，减小了第一吹气管10的冷却压力，提高了燃烧装置整体工作时的稳定性。
