Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0020] Please refer to Figures 1-3 , which is the first embodiment of the present utility model. This embodiment provides a compound heat exchanger, including an outer shell 1 and a maintenance component. The maintenance component includes an extension part 15 and a protective seat 3. The extension part 15 is arranged at the bottom of the outer shell 1, realizing the addition of the extension part 15. The extension part 15 is of an annular structure, and an external thread 150 is arranged on the outer wall of the extension part 15, realizing the addition of the external thread 150. An internal thread 31 is arranged on the inner wall of the protective seat 3, realizing the addition of the internal thread 31. The internal thread 31 and the external thread 150 are meshed and connected. By using the cooperation of the internal thread 31 and the external thread 150, it helps to realize the disassembly and assembly of the protective seat 3 and the outer shell 1.

[0021] In this embodiment, preferably, a connecting cylinder 81 is provided on the inner wall of the extension part 15, realizing the addition of the connecting cylinder 81. A support ring 8 is provided on the connecting cylinder 81. The connecting cylinder 81 increases the limitation on the support ring 8. A motor 82 is installed on the top of the support ring 8 by screws. The support ring 8 increases the support for the motor 82. When the protective seat 3 is detached from the housing 1, it is convenient to maintain the motor 82.

[0022] In this embodiment, preferably, the output shaft of the motor 82 is connected to a rotating ring 4. When the motor 82 works, it can drive the rotating ring 4 to rotate. Four partition plates 41 are provided on the rotating ring 4, realizing the addition of the partition plates 41. A working chamber is formed between two adjacent partition plates 41 and the housing 1. The housing 1 is provided with a first heat exchange chamber 11, a second heat exchange chamber 12, a heat preservation chamber 13, and a preheating chamber 14. The working chamber is used in cooperation with the first heat exchange chamber 11, the second heat exchange chamber 12, the heat preservation chamber 13, and the preheating chamber 14. The motor 82 drives the working chamber to rotate through the first heat exchange chamber 11, the second heat exchange chamber 12, and the heat preservation chamber 13 in sequence. Different heat exchange devices are arranged in different heat exchange chambers to achieve the purpose of heat exchange while rotating, avoiding the drawback of the single traditional heat exchange method.

[0023] In this embodiment, preferably, a heat exchange member 5 is installed inside the first heat exchange chamber 11. The heat exchange member 5 is composed of a hot air blower and heat exchange tubes. The outlet of the hot air blower is connected to the heat exchange tubes through a connecting pipe.
