Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain, broadly fall into the scope of protection of the invention.
According to embodiments of the invention, it is provided that a kind of coaxial finned heat exchanger.
As shown in Figure 1, coaxial finned heat exchanger according to embodiments of the present invention includes heat exchanger tube 1, described heat exchanger tube 1 is evenly arranged with some heat exchange fins 2, and, the outside of described heat exchanger tube 1 is sequentially coaxially provided with interior bile duct 3 and outside lining pipe 4, wherein, described interior bile duct 3 is respectively arranged with air inlet 5 and gas outlet 6, described outside lining pipe 4 is respectively arranged with inlet 7 and liquid outlet 8.
When specifically used, with temperature gas (such as, high-temp waste gas) import in interior bile duct 3 by air inlet 5, now, heat exchanger tube 1 and outside lining pipe 4 are filled with coolant, gas in internal bile duct 3 carries out inside and outside cooling down simultaneously, thus being greatly improved the heat exchange efficiency of heat exchanger.
In one embodiment, in order to ensure mobility and the distributivity that in interior bile duct 3, gas is balanced, air inlet 5 can be arranged at the upside of interior bile duct 3 one end, and gas outlet 6 is arranged at the downside of interior bile duct 3 other end, thus the mobility of the gas that well ensure that in interior bile duct 3, prevent head-on collision and the skewness of gas, and then ensure that heat exchange efficiency to a certain extent.
