Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In this disclosure, unless otherwise indicated, terms of orientation such as "inner and outer" are used to refer to the inner and outer contours of the components themselves. The terms "first" and "second" are used herein to distinguish one element from another without sequence or importance.

According to a specific embodiment of the present disclosure, there is provided a heat exchanger, referring to fig. 1, the heat exchanger includes a heating structure 1, a smoke extractor 2, and a heat exchange tube, the heating structure 1 is in communication with the smoke extractor 2, the smoke extractor 2 is configured to exhaust smoke from the heating structure 1, the heat exchange tube includes a water inlet 31, a first heat exchange tube 32, a second heat exchange tube 33, and a water outlet 34, which are sequentially communicated, the first heat exchange tube 32 is disposed in the smoke extractor 2 and is configured to perform heat exchange with smoke in the smoke extractor 2, and the heating structure 1 is configured to heat water in the second heat exchange tube 33.

Through above-mentioned technical scheme, in the heat exchanger that this disclosure provided, can advance first through water inlet 31 into first heat exchange tube 32, this disclosure is through setting up first heat exchange tube 32 on fume extractor 2 and with the flue gas in the fume extractor 2 to through setting up first heat exchange tube 32 in the upstream of second heat exchange tube 33, like this, water can absorb the waste heat of the flue gas in fume extractor 2 earlier through first heat exchange tube 32, then get into second heat exchange tube 33 and be heated by heating structure 1, like this, can effectively improve heat exchange efficiency of heat exchanger, and reduced the waste of the waste heat of the flue gas in fume extractor 2.

The first heat exchange line 32 may be disposed inside the smoke extractor 2 to exchange heat with the smoke of the smoke extractor. Here, according to some embodiments, the first heat exchange line 32 may include a pipe segment (not shown) disposed in a smoke exhaust pipe (not shown) of the smoke exhaust 2. Thus, the heat exchange efficiency of the two can be improved by directly contacting the branched pipe sections with the flue gas.
