As Figure 1-Figure 2, a kind of no-welding stainless steel heat exchanger, which is characterized in that including：End cap 1, side plate 2, combustion
Room 3, fixing bolt 4 and several thermal-collecting tubes 5 are burnt, the end cap 1 includes first end cover 1-1 and second end cover 1-2, the side plate 2
Including the first side plate 2-1 and the second side plate 2-2；It is respectively equipped with correspondence on the first side plate 2-1 and the second side plate 2-2
Hole, the both ends of each thermal-collecting tube 5 are assembled with corresponding hole respectively；The first end cover 1-1 and second end cover 1-2 points
It An Zhuan not be on the first side plate 2-1 and the second side plate 2-2, for each thermal-collecting tube 5 is layered different layers, respectively
Layer connection；The combustion chamber 3 is arranged between the first side plate 2-1 and the second side plate 2-2；The fixing bolt 4 is worn
Both ends are locked after crossing the first end cover 1-1, the first side plate 2-1, the second side plate 2-2 and the second end cover 1-2
Tightly, make between the both ends of each thermal-collecting tube and the first side plate 2-1 and the second side plate 2-2 and first side plate
2-1 and the second side plate 2-2 with accordingly be close to seal between the first end cover 1-1 and the second end cover 1-2.
Wherein, the first side plate 2-1, the second side plate 2-2, combustion chamber 3 and thermal-collecting tube 5 are all stainless steel part.Described
One end cap 1-1 and second end cover 1-2 is aluminium alloy castings.
There is gasket 7 between the side plate 2 and end cap 1, to ensure sealing effect.The combustion chamber 3 does not have and side plate 2
Inner wall is connected, and has seldom one intersegmental gap, as long as this intersegmental gap plays heat-blocking action, prevents 2 temperature of side plate excessively high.Thermal-collecting tube and
Side plate is connected by sealing ring 8.
Several outwardly projecting connectors 9 are respectively equipped on the first end cover 1-1 and the second end cover 1-2, respectively
It is connected by corresponding bend pipe 10 between the connector 9, to make different layers be connected to.
As shown in figure 3, the thermal-collecting tube 5 is preferably light pipe, without fin.Light pipe both ends are processed by mold, are allowed to shape
At boss 11, sealing ring 8 can be filled on boss 11, the diameter of the boss 11 is more than the diameter in the hole 6.
The structure of side plate 2 is as shown in figure 4, each hole 6 in thermal-collecting tube 5 and side plate 2 corresponds.
Specific installation fit system at the boss 11 of thermal-collecting tube 5 as shown in figure 5, put in sealing ring 8 and side plate 2
Hole 6 cooperates, and the diameter of boss 11 is more than the diameter of side plate mesoporous 6, plays the role of limit.Have among end cap 1 and side plate 2
Gasket 7 seals, be allowed to the flows of different layerings by end cap 1 and between gasket 7 be spaced from each other.The external structure of end cap
As shown in fig. 6, the water in thermal-collecting tube 5 is divided into the flow of different layers by end cap 1, it is allowed to the circulating-heating in thermal-collecting tube 5.Layer with
Flow between layer is connected by bend pipe 10.
A kind of no-welding stainless steel heat exchanger provided in this embodiment, the both ends of thermal-collecting tube 5 and side plate 2 pass through sealing ring
8 link together, and side plate 2 is linked together by gasket 7 and end cap 1, due to there is the limit of boss 11 on thermal-collecting tube 5, so
Left and right side pressure can be fastened by fixing bolt 4, not only can ensure to seal, avoid the welding of stainless steel；And
And the quantity of thermal-collecting tube can increase or reduce according to actual conditions.
Internal combustion chamber space is as shown in fig. 7, the thermal-collecting tube 5 of 3 both sides of combustion chamber is used for absorbing waste heat to reduce side plate
Wen Sheng, top is main heat exchange area.One section of space is reserved between combustion chamber 3 and side plate 2, since side plate 2 and thermal-collecting tube 5 are to pass through
Sealing ring seals, and can prevent 2 temperature of side plate excessively high in this way, to improve the reliability of gasket 7 and sealing ring 8.
As shown in Figure 8, Figure 9, free assembling is carried out according to actual needs since the quantity of thermal-collecting tube 5 is convenient, by collection
The layout of heat pipe can quickly realize upright installation and handstand two kinds of mounting means of installation.
When handstand installation, burner is mounted on the top of heat exchanger, is followed successively by main heat exchange area 12 and condensation from top to bottom
Heat transfer zone 13, increases the quantity of heat exchanger tube, realizes main heat exchange and condensing heat-exchange one, due to being installation of standing upside down, condensed water by
The effect of gravity, flows downward and excludes.
From the foregoing description of structures and principles it should be understood by those skilled in the art that, the present invention not office
It is limited to above-mentioned specific implementation mode, uses the improvement of techniques well known and replacement to all fall within this hair on the basis of the present invention
Bright protection domain, protection scope of the present invention should limit it by each claim and its equivalent.In specific implementation mode
The part not illustrated is the prior art or common knowledge.
