[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0037] Example 1: A heat exchange device for recovering waste gas from a cooking machine, see [link / reference] Figures 1 to 4 It includes an end box 1 and a heat exchanger body 2, with the heat exchanger body 2 arranged between the two end boxes 1, and also includes a protective structure 3; the protective structure 3 is arranged above the heat exchanger body 2.

[0038] The protective structure 3 includes a cover plate 301 and side plates 302; the cover plate 301 is arranged above the heat exchanger body 2; the two side plates 302 are respectively arranged at the front and rear ends of the cover plate 301.

[0039] This utility model, by setting a cover plate 301 and a side plate 302, has the advantage of protecting the area above the heat exchanger body 2 and preventing direct impact on the heat exchanger body 2. It solves the problem that when the heat exchanger is located on the ground, objects falling from above will hit the heat exchange mesh and easily cause damage.

[0040] Specifically, baffles 4 are fixedly installed at the top of the two end boxes 1 respectively, and cover plates 301 are arranged between the two baffles 4. The side of the cover plate 301 is supported and cooperated with the top of the end box 1.

[0041] This utility model has the advantage of setting baffles 4, which limits the cover plate 301 when it is placed, so that the cover plate 301 can be placed accurately.

[0042] Furthermore, the inner side of the top of the baffle 4 is provided with a slope 401, and a larger opening is formed between the two baffles 4, which facilitates the placement of the cover plate 301.

[0043] Furthermore, both ends of the side plate 302 are connected to the cover plate 301 via several connecting components 303;

[0044] The connecting assembly 303 includes a connecting rod 3031, a limiting block 3032, and a spring 3033. The connecting rod 3031 passes through a hole at the end of the side plate 302. The inner end of the connecting rod 3031 is fixedly connected to the cover plate 301. The limiting block 3032 is fixedly mounted on the outer end of the connecting rod 3031. The spring 3033 is sleeved on the connecting rod 3031 between the limiting block 3032 and the side plate 302. Both ends of the spring 3033 are fixedly connected to the limiting block 3032 and the side plate 302, respectively.
