Abstract
The present invention belongs to a heat exchanger, which comprises a furnace body, wherein a combustion chamber is arranged inside the furnace body; a water sleeve is arranged outside the combustion chamber; a smoke discharge channel is outwardly led out of the combustion chamber which is provided with a heat pipe group, one end of each heat pipe of the heat pipe group is totally inserted into the water sleeve, and the other end is inserted into the combustion chamber. The present invention is characterized in that the outer part of every heat pipe which is inserted into one end of the combustion chamber is sheathed with an outer sleeve which is made of heat conducting material and is connected with the body wall of the water sleeve into a whole. The present invention has the advantages of convenient assembly and disassembly, simple structure, etc. No water penetration is in the combustion chamber.
Description
The invention belongs to a kind of boiler.
Common boiler as the essential structure of hot-water boiler, drinking water boiler is: comprise the body of heater of inner band combustion chamber, be provided with water jacket in the outside, combustion chamber, outwards draw smokejack from the combustion chamber.By the burning of fuel in the combustion chamber, the water among the heating water jacket.Calory burning is to conduct to water in the water jacket by the base plate of water jacket and side plate.Because the thermal conductivity factor of water jacket material is not high, so the thermal efficiency of boiler is very low.In addition, easily during boiler combustion cross heating and cause the water jacket explosion accident.Therefore the security of boiler is relatively poor.
For overcoming above shortcoming, many boilers that utilize heat pipe, be suggested as the design of tubular boiler.Be 93226699.1 Chinese patent application as application number: it is equiped with the heat pipe group, and an end of each heat pipe of heat pipe group all is placed in the water jacket, the other end then is inserted in the combustion chamber.Because the thermal conductivity factor of heat pipe is high, so when the fuel combustion of combustion chamber, combustion heat energy can be conducted to the water in the water jacket with high conversion ratio by heat pipe.So boiler thermal output height.Have, when burning was excessive, heat pipe reaches uniform temperature can damage, lose heat transmission function voluntarily again.So there is not the problem of over-heating, safe and reliable.
But above tubular boiler also exists such problem: inserted water jacket body wall place at heat pipe, water infiltrates the combustion chamber in the unavoidable water jacket.In application number is 94226847.4 Chinese patent application, has disclosed and a kind ofly inserted water jacket body wall place at heat pipe and insert airtight and watertight padding to solve the scheme of seepage problem.But, because the flame resistance of airtight and watertight padding etc. is had relatively high expectations, increased material cost, main is that this makes the heat pipe mounting structure complicated, and the heat pipe that has burnt is keeped in repair and change very inconvenience.
At application number is that its heat pipe and water jacket are integrally welded in 95208725.1 the Chinese patent application disclosed " heat pipe boiler ".Though it can avoid the combustion chamber seepage problem, the heat pipe maintain and replace is almost impossible.
Purpose of the present invention just is to provide in a kind of combustion chamber and does not seep water, convenient, the simply constructed tubular boiler of heat pipe mounting or dismounting.
The object of the present invention is achieved like this: it comprises the body of heater of inner band combustion chamber, be provided with water jacket in the outside, combustion chamber, outwards draw smokejack from the combustion chamber, and be equiped with the heat pipe group, an end of each heat pipe of heat pipe group all is placed in the water jacket, the other end then is inserted in the combustion chamber; It is characterized in that: be with the overcoat of Heat Conduction Material system in the outside that is inserted in an end in the combustion chamber of each heat pipe, this overcoat and water jacket body wall fuse.
A part of heat pipe can be that an end is placed in that the other end then is inserted in the flue in the said water jacket among the heat pipe group.
Moreover heat pipe the group preferably be arranged in parallel by several column, and adjacent two row heat pipes are staggered.
Moreover, be preferably in said flue external wall of upper portion and place in the said water jacket and be with fin.
Moreover, be preferably in said flue inwall and lay spinning disk.
Because the outside of heat pipe is with overcoat, and this overcoat and water jacket body wall fuse, so heat pipe is inserted in the combustion chamber with complete sealing state, do not have seepage problem.Because overcoat is a Heat Conduction Material system, does not influence heat pipe work.In addition, heat pipe can be lived and be inserted in the overcoat the inside, when heat pipe is burnt or other problem occurs, can keep in repair easily, change.This shows the present invention have in the combustion chamber do not seep water, advantages such as heat pipe mounting or dismounting convenience, simple structure.
Further specify the present invention below in conjunction with embodiment.

Embodiment 1
According to Fig. 1 and 2, boiler of the present invention is a kind of boiler, comprises the body of heater 1 of inner band combustion chamber 2, and the smokejack 5 of " L " shape is drawn in 2 side upper end in the combustion chamber, water jacket 4 is enclosed within body of heater 1 top and flue 5 outsides, and water jacket 4 lower-left ends are brought the mouth of a river 7 into, upper right side is taken the mouth of a river 6 out of.Be equiped with the heat pipe group, an end of each heat pipe 3 of heat pipe group all is placed in the water jacket 4, the other end then is inserted in combustion chamber 2 and flue 5 in.The outside that is inserted in an end in the combustion chamber 2 at each heat pipe 3 is with overcoat 8, and this overcoat 8 fuses with water jacket 4 body walls.In the present embodiment, overcoat 8 is integrated in the bottom surface of water jacket 4.Generation type can be: the system of opening on water jacket 4 bottom surfaces is welded the cylindrical shell that an internal diameter is same as this hole at tapping then with the close hole of the bore of heat pipe 3.The shape of cylindrical shell will determine according to the shape of heat pipe, such as being garden shape, square etc.The internal diameter of cylindrical shell has the size of some friction degree to be advisable with the heat pipe 3 and the barrel that can make insertion.Guarantee that so promptly heat pipe 3 do not swing, can pull down heat pipe 3 easily again.The material of overcoat 8 is advisable with the metal material of good heat conductivity.
In the present embodiment, the heat pipe group be arranged in parallel by several column, and adjacent two row heat pipes 3 are staggered, and this is in order to allow the water that flows through contact, fully to be heated with heat pipe more than 3.
