Below operation and the effect that an embodiment of the present invention will be described.
Be installed in the heat of high temperature that gas produced of the burner combustion of gas fired-boiler bottom, by the upwards transmission of thermofin 200 of layout parallel to each other.Because the indoor heating pipe 228 laterally inserted thermofins 200 of layout parallel to each other, this heat of high temperature are heating indoor heating pipe 228 by thermofin 200 time.After indoor heating pipe 228 was heated, the water that flows through indoor heating pipe 228 is heated to was enough to reach the needed high temperature of indoor heating water, and indoor heating water just is fed to actual room heater tube portion (not shown) from the indoor heating pipe.When from the heat of burner when uploading between the thermofin 200, heat arrives the lower surface of indoor heating pipe 228.Therefore, hot-fluid is divided into both direction, and for example, with respect to each indoor heating pipe 228, hot-fluid is divided into left and right sides both direction, and the hot-fluid that separates still upwards is passed to the upper surface of indoor heating pipe 228.Thereby hot-fluid heating indoor heating pipe 228.In addition, the hot-fluid that separates arrives the downside of the air-flow targeting part that is distributed in indoor heating pipe 228 left and right directions, and still is passed to the upper surface of indoor heating pipe 228 along this downside.So, the heat that the separates heating that indoor heating pipe 228 is also flowed on indoor heating pipe 228 upper surfaces.
The heat exchanger that has thermofin according to the embodiment of the invention, when the heat of high temperature of gas combustion generation in the burner is passed through heat exchanger, heat be subjected to being arranged between adjacent two indoor heating pipes, the position is higher than the guiding of the air-flow targeting part of row's indoor heating pipe position, surrounded all surfaces of indoor heating pipe, that is to say that heat is in the upper and lower transmission of indoor heating pipe.So when air-flow targeting part during to the heat channeling conduct, all surface of indoor heating pipe absorbs heat rapidly, and without any the heat diffuse reflection, so that the efficient of heat exchanger has improved greatly, atmospheric pressure lost has also reduced.Therefore, owing to use less thermofin can obtain higher heat exchanger effectiveness, the volume of heat exchanger can be littler.
In addition, when heat is subjected to the guiding of air-flow targeting part, and when not having any diffuse reflection and taking place, because heat along the upper surface transmission of indoor heating pipe, can reduce atmospheric pressure lost, so the interval between the indoor heating pipe can reduce.Thereby the volume of heat exchanger can be littler.
In addition, because the interval between the indoor heating pipe reduces, the indoor heating pipe is more near the air-flow targeting part.Therefore, heat exchanger effectiveness has improved greatly, and the thermic load of thermofin has reduced because the heat that thermofin absorbs can be delivered to the indoor heating pipe rapidly, so that the not influence of affected by hot loading of portion of hot interchanger.
And because the air-flow targeting part is arranged near the indoor heating pipe bottom, the indoor heating pipe has absorbed the heat that is transmitted by the air-flow targeting part rapidly.Therefore, can protect thermofin, the upwards infringement of the heat of transmission that makes it not produced by burner.
Obviously, those skilled in the art can make various remodeling within the spirit and scope of the present invention.Therefore the protection domain of back appending claims is not subjected to the restriction of aforementioned specification; and claims comprised of the present invention all have the novel feature of patentability, comprise the equivalence techniques feature that all that those of ordinary skill in the art can expect.
