Description

Normal pressure high-efficiency heat pipe water heater

The utility model relates to a kind of normal pressure high-efficiency heat pipe water heater, and it is a thermal source with fuel oil, combustion gas.

Existing fuel oil or gas water-heating furnace are various informative, they improve the thermal efficiency by the heating surface area that increases radiation or convection current, its thermal efficiency about 90%, though its thermal efficiency is higher, but still owing to reasons such as fuel prices, its operating cost is higher, therefore, is necessary to provide a kind of novel normal pressure efficient water heater.

The purpose of this utility model provides a kind of normal pressure high-efficiency heat pipe water heater, this stove quick heating, and efficient is higher, and energy savings is remarkable, and its thermal source is combustion gas or fuel oil.

For achieving the above object, the utility model is taked following design: this normal pressure high-efficiency heat pipe water heater comprises counter-burning type combustion chamber, body of heater, furnace bottom, smoke exhaust pipe, be provided with high-efficiency heat pipe in the described combustion chamber smoke tube chamber, the heat pipe heat radiation end stretches in the body of heater, water inlet is arranged, delivery port in body of heater.

The utility model has the advantages that: novel structure, the counter-burning type combustion chamber adds regenerative apparatus, improves chamber temperature, fuel is burnt to greatest extent, avoid smoke pipe, smoke chamber greasy dirt to form, adopt many group high-efficiency heat pipes to absorb considerable part radiant heat and advection heat, directly import and be heated in the water, further strengthen heat exchange area, this water heater quick heating, efficient height, energy-saving effect is remarkable, maintenance capacity is little, and operating cost is low, is applicable to the every profession and trade needs.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2,16 is body of heater, and 1 is furnace bottom, be arch, can accumulation of heat, reduce the loss, the radiant heat that forms further guarantees the abundant after-flame of oil plant, 2 is the counter-burning type combustion chamber, and so-called counter-burning type combustion chamber is that its burner is positioned at the top, combustion chamber, and purpose is to increase cigarette, thermal flow process, make it that abundant heat-exchange time be arranged, the corresponding raising of room temperature makes full combustion of fuel, and 9 is the burner installing hole.Establish accumulation of heat wall 3 in the flame combustion chamber end, avoid the directly cold wall of contact of duration and degree of heating, guarantee that oil plant fully burns, be provided with smoke exhaust pipe 4 at combustor exit, smoke exhaust pipe is a multi-cavity, and high-efficiency heat pipe 5 (see figure 2)s are arranged between two smoke exhaust pipes, and its heat pipe quantity can be 8,10,12,20 etc.In smoke exhaust pipe, the helical resistive smoked sheet can be set, to strengthen the tube wall heat absorption capacity.Flue gas enters secondary smoke exhaust pipe 7 through one-level smoke exhaust pipe 4, and flue gas by convection current and radiation, imports heat energy into being heated in the water in the body of heater in stroke.In the combustion flame end high-efficiency heat pipe 6 is arranged, its quantity can be 5,6,7 etc.8 is that the high-efficiency heat pipe figure 14 that an end is arranged in the secondary smoke exhaust pipe is exhaust opening, 10 is water inlet, 12 delivery ports, 11 is sewage draining exit, 13 is explosion relief, is furnished with communicating pipe 15 in the periphery of exhaust opening among the figure, and the current that are positioned at the upper and lower position of smoke exhaust pipe are linked up, help conducting heat, increase the heat transfer area of flue again.

Fig. 3, Fig. 4, shown in Figure 5,5 is high-efficiency heat pipe, and it comprises that airtight heat pipe 5-1,5-2 are the fin that is positioned at periphery, heat pipe bottom, and 5-3 uses flange for connecting.In the same another kind of form high-efficiency heat pipe, 5-4 is a flange, and heat pipe 5-5 bottom is an annular 5-6, has increased heat transfer area, so be not with fin.Three groups of heat pipes are arranged in the present embodiment, its radiating end lays respectively in the body of heater down, in, the upper part.The heating end of three groups of high-efficiency heat pipes absorbs a large amount of convection current and radiant heat, and imports and to be heated in the water, therefore, can make full use of the heat that fuel combustion produces, and exhaust gas temperature keeps 150 ℃, and the thermal efficiency reaches more than 94%.
