Description
Technical field
The present invention relates to the heat exchanging bodies used in gas heater technical field more particularly to condenser.
Background technology
The heat exchange efficiency of condenser is one improved target of those skilled in the art, and existing condensing heat-exchange body is because of heat-exchange time
It is short and there are heat exchange efficiency it is low the problem of.In addition, existing conventional condensing heat exchanger, although the material of its heat exchanging body base material is not
One, but no matter which kind of base material, multiselect welding procedure is isolated by exhaust gases passes and water stream channel, and is welded and be susceptible to two
Latent defect：One is welding quality ensures problem, because heat exchanging body needs resistance to higher hydraulic pressure, experiment pressure voltage reaches 2MPa, this
It is very high to weld seam quality requirement, virtually improve manufacture cost；The second is welding weld seam cannot be avoided to adulterate completely, also without
Method ensures welding heat affected zone stress elimination and performance reaches substrate performance, causes heat exchanging body in the region of water quality inferiority easily because of acid
After property condensed water or ordinarily resident's aqueous corrosion, welding position occurs rupturing or drainage.
Invention content
In view of this, the purpose of the present invention is exactly to be intended to increase aqueous vapor heat exchange area by providing a kind of heat exchanging body, is improved
Heat exchange efficiency.
A kind of heat exchanging body including main body, on the body equipped with outer heat exchanger fin, is equipped at least two in the main body
Water flow passage is equipped at least two exhaust gases passes in the main body.Multiple exhaust gases passes and water flow passage are equipped in main body, it can
The heat exchange area of water and flue gas is improved, and then improves heat exchange efficiency.For example set in the main body there are four exhaust gases passes, this
Four independent exhaust gases passes rely solely on the heat exchange of external heat-exchanging piece relative to existing heat exchanging body, absorb the face of flue gas heat
Product increased.
Further, the exhaust gases passes are internally provided with interior heat exchanger fin, can further expand the heat exchange area of water and flue gas.
Further, it is set between four exhaust gases passes there are four linear water flow passage, four water flow passages are in
Cross.How to arrange that water flow passage could be so that the area maximum of water and flue gas heat exchange be this field between four exhaust gases passes
Technical staff's problem needed to be considered in the technical program, arranges water flow passage cruciferous between four exhaust gases passes,
It can not only ensure water and flue gas by enough heat exchange areas, moreover it is possible to so that heat exchanging body is compact-sized.
Further, at least four arc water flow passages are formed between exhaust gases passes and body outer wall at described four, this
Sample can utilize the heat exchanger fin of main body to absorb the heat feedwater heating of flue gas, and arc water flow passage is designed according to the shape of main body,
Due between four exhaust gases passes there are four linear water flow passage, in order to be connected with this four linear water flowings, just in cigarette
At least four arc water flow passages are formed between gas channel and body outer wall, can so ensure the middle water flow passage of heat exchanging body is all
Connection, flow can be made smoothly to flow out heat exchanging body.
Be provided between the water flow passage water passage either water hole by the water passage or water hole,
Flow flows between the water flow passage.Next flow is flowed to from a water flow passage by water passage or water hole flow
Road, the water passage or water hole can be open-minded on the spacing board of water flow passage.But in partition board trepanning or channel, add
Work difficulty is big so that heat exchanging body is difficult to be integrally formed, for this purpose, being equipped with partition board, the partition board between the adjacent water flow passage
Shorter than described water flow passage forms water passage between the partition board and the water flow passage in the gap of heat exchange body axis direction.
In this way when flow flows to the end of water flow passage, it is possible to cross the partition board into next water flow passage, in this way without every
Hole machined is carried out on plate, simplifies the processing technology of heat exchanging body, can thus so that heat exchanging body is integrally formed
The water passage includes top water passage and bottom water passage, and water is crossed in the top water passage and bottom
Channel is arranged alternately between the water flow passage.Top water passage is exactly that flow is crossed at the top of heat exchanging body under partition board entrance
One water flow passage, bottom water passage are exactly that flow crosses partition board in the bottom of heat exchange figure into next water flow passage.Such energy
Enough so that flow can flow back and forth in heat exchanging body, flow flows back and forth in heat exchanging body, constantly carries out hot friendship with flue gas
It changes, extends heat-exchange time, improve heat exchange efficiency.
Further, positioning device is equipped at least one end face of the heat exchanging body.Positioning device is used for and water seal cover
Coordinate, the positioning device on heat exchanging body can be locating slot or locating piece.
Compared with prior art, it is of the invention to include at least following advantageous effect：
(1) there are multiple water flow passages and exhaust gases passes in the heat exchanging body in the present invention, increase water and flue gas heat exchange area, carry
High heat exchange efficiency.
(2) present invention improves heat exchange area using most compact runner arrangement, and under the requirement of the identical thermal efficiency, this is changed
Length needed for hot body is small.
(3) water flow passage of the invention and exhaust gases passes concentrated setting reduce other accessories in the main body of heat exchanging body
Processing request.
(4) heat exchanging body in the present invention can intercept different length according to thermal efficiency requirements, general without changing other structures
Property is high.
(5) extrusion process can be used in the heat exchanging body in the present invention, and welding stress is avoided to concentrate.
