Description

Hot water circulation type hot-tube heater

The utility model relates to the heating heater that the general family of a kind of confession and office use, and is in particular a kind of hot water circuit formula heat pipe heater.

Home-use warmer has many kinds at present, uses space heater the most generally, as electric heating installation using oil as medium, quartz ampoule, resistance wire, PTC ceramic electric heater etc., the general power of these space heater is that 500-2000W does not wait, general family is owing to the ammeter capacity limit, and when power consumption surpassed 1000W, the ammeter load was excessive, need the big capacity ammeter of repacking, this investment must be more than thousand yuan, and space heater can only use in a room, can not use in several rooms simultaneously.General subsection is not owing to there is Boiler Steam to supply with, and heating also is a problem, and placement boiler investment cost is big, and needs specialty operation stoker.

The purpose of this utility model is exactly to provide a kind of hot pipe technique that utilizes to come water in heating furnace and the flue interlayer for the above-mentioned defective that overcomes prior art, carry out hot water circuit by feed pipe and return pipe, for the hot water circuit formula heat pipe heater of room heating.

Technical solution of the present utility model is as follows:

A kind of hot water circuit formula heat pipe heater, it comprises heating furnace, heat pipe, feed pipe, return pipe is the combustion chamber from bottom to up in the heating furnace, burner hearth, flue, flue outlet, perisporium at flue is provided with a water interlayer, and heat pipe is arranged in the stove internal perisporium, and its cooling section just is inserted in the water interlayer, its bringing-up section is positioned at burner hearth, also tilts to be provided with several finned tubes in flue, and this finned tube all links with water interlayer 9, on heating furnace, also be provided with the feed water inlet that links with water interlayer, water return outlet, water inlet.

Advantage of the present utility model is applicable to pluralities of fuel, its heat pipe is arranged in the burner hearth perisporium, and water leg is extended down to the exhaust opening place, and the ratio-frequency welding spirality finned tube that is in tilted layout in flue, its heat exchange efficiency height, compare with present hot-water heater, the thermal efficiency can improve 20-30%, and floor space is little, simple in structure, processing ease can satisfy different heating requirements, and can provide to have a bath and live and use hot water.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model user mode schematic diagram

Fig. 2 is the utility model heating furnace structure schematic diagram

Fig. 3 is the utility model finned tube scheme of installation

As shown in Figure 1-Figure 3, during the utility model work, its heating furnace 1 applicable pluralities of fuel, as artificial coal gas, liquefied petroleum gas, fuel oil, coal etc., heat pipe 2 are arranged in around the burner hearth 6, heat pipe 2 bringing-up sections two side external surfaces are welded with straight fins 17, absorb the radiations heat energy in the burner hearth 6, heat pipe 2 cooling sections 10 are longer than bringing-up section 11, and heat pipe 2 operating temperatures are reduced, and can reduce the temperature of burner hearth 6 perisporiums, prolong the service life of heat pipe, the finned tube 12 in the flue 7 is to be in tilted layout in flue 7 by the stagger arrangement of flue gas flow path direction, and the fin 16 on finned tube 12 outer surfaces is the ratio-frequency welding helical fin of welding, it has strengthened finned tube 12 outer heat exchange areas, flue gas flows outside finned tube 12 like this, and water flows in pipe, and the gas converting heat coefficient is significantly smaller than the coefficient of heat transfer of water, thereby can solve the problem that both coefficients of heat transfer differ greatly effectively, the finned tube 12 that is in tilted layout in addition can form convection current when making the water boiling and rise, and strengthens heat-transfer effect.The water interlayer 9 of flue 7 perisporiums can be extended down to flue outlet 8 places can further absorb fume afterheat, improves heat efficiency of heater.Feed water inlet 13, water inlet 15, all be located at the upper end of water interlayer 9 on the heating furnace 1, water return outlet 14 is located at the lower end of water interlayer 9 on the heating furnace 1, the lower end of water interlayer 9 also is provided with the sewage draining exit 18 of sewer effect together on body of heater 1, feed water inlet 13 links with feed pipe 3 and links with corresponding radiator 22 by each control valve 21 and heats, and the backwater of radiator 22 links by return pipe 4 and water return outlet 14, to realize periodical feeding, running water links by water intaking valve 20 and water inlet 15.And be provided with the safety vent device at water inlet 15 places, during use, at first unclamp the block on the emptying device that links with water inlet 15, whole device is communicated with atmosphere, open the tap 19 of control sewage draining exit 18 then, open the water intaking valve 20 of control water inlet 15 again, when waiting the atmospheric valve place of radiator 22 to have water to overflow, close water intaking valve 20 again, finish to heating furnace 1 and add water.Connect source of the gas and light heating furnace 1, after 15 minutes, can hear water boiling in the heating furnace 1 approximately excessively, unclamp the vent valve of radiator 22 this moment again, the air in the removal system is tightened air bleeding valve then up to there being steam to emerge, and, can warm oneself according to the different opening controlling valve doors 21 that require.
