Referring to fig. 4, specifically, two side surfaces of one end of each first installation opening 111 close to the edge of the first partition plate 11 are respectively provided with one water inlet hole 121, so that the middle part of the end surface of one end of the first installation opening 111 close to the edge of the first partition plate 11 does not need to be provided with the water inlet hole 121, but directly abuts against the tube wall of the first heat exchange tube 41, thereby realizing the fixing effect of the first heat exchange tube 41. It should be noted that the size of the water inlet hole 121 is not limited, and when the size of the water inlet hole 121 is larger, the width of the end face of the first mounting opening 111 close to the edge of the first partition plate 11 is smaller; the smaller the size of the water inlet hole 121 is, the larger the size of the end surface of the first mounting opening 111 near the edge of the first partition plate 11 is.

In one embodiment, the first separation plate 11 is at least two, and the second separation plate 12 is at least two. At least two first partition plates 11 and at least two second partition plates 12 are alternately arranged in the water storage chamber 31.

In one embodiment, a cooling chamber 35 communicating with the water storage chamber 31 is formed between the side walls of the first housing 20 and the second housing 30, and the cooling chamber 35 is disposed around the combustion chamber 21. So, because the cooling chamber 35 of tubular heat exchanger sets up around burning chamber 21, consequently, rivers (the temperature generally is about 65 ℃) in the cooling chamber 35 can surround burning chamber 21, with the outer wall (the during operation of first casing 20, the burning temperature can reach about 1200 ℃ in burning chamber 21, can carry out heat radiation to the wall of first casing 20) the abundant contact heat transfer, effectively reduce the outside surface temperature of first casing 20, so, compare in traditional equipment, the tubular heat exchanger of this embodiment encloses cooling chamber 35 through enclosing between first casing 20 and the second casing 30, need not like the coil form that traditional heat exchanger adopted, effectively solve the too big problem of pipeline overlength water resistance.

It should be noted that the arrangement of the supercooling cavity 35 around the periphery of the combustion chamber 21 is to be understood as follows: the cooling chamber 35 surrounds the entire periphery of the combustion chamber 21, i.e. 360 ° surrounds the combustion chamber 21, please refer to fig. 2; alternatively, the temperature reducing chamber 35 surrounds a portion of the periphery of the combustion chamber 21, i.e., the temperature reducing chamber 35 does not surround the combustion chamber 21 360 °. At this time, when the second housing 30 is sleeved outside the first housing 20, at least one outer side surface of the first housing 20 is attached to at least one inner side surface of the second housing 30, so that the cooling cavity 35 is or is approximately in a "C" shape.

Referring to fig. 6 to 8, in an embodiment, the cooling cavity 35 and the combustion cavity 21 are located above the water storage cavity 31, the water inlet pipe 32 is disposed on a bottom end plate (corresponding to the second end plate 37) of the second housing 30, and the water outlet pipe 33 penetrates through the bottom end plate of the second housing 30, extends into the cooling cavity 35 through the water storage cavity 31, and is communicated with the cooling cavity 35. Like this, on the one hand, inlet tube 32 runs through behind the bottom end plate of second casing 30 and is linked together with water storage chamber 31, and not set up on the lateral wall (corresponding to second bounding wall 36) of second casing 30 to can not occupy the side space of second casing 30, and similarly, outlet tube 33 also runs through behind the bottom end plate of second casing 30 and passes water storage chamber 31 and stretch into cooling chamber 35, and second casing 30 also does not set up on the lateral wall of second casing 30 like this, also can not occupy the side space of second casing 30, thereby can reduce the volume size of cast heat exchanger. On the other hand, because the flue gas in the combustion chamber 21 is discharged downwards through the heat exchange tube 40, the condensed water generated on the inner wall of the heat exchange tube 40 is conveniently discharged downwards along with the flue gas, and a good heat exchange effect is kept. Meanwhile, carbon deposit and ash deposit on the inner wall of the heat exchange tube 40 are reduced, and a good heat exchange effect is kept.

It should be noted that, as an alternative, the water inlet pipe 32 is not limited to be disposed on the bottom end plate of the second casing 30, and may also be disposed on the side wall of the second casing 30. The water outlet pipe 33 is not limited to be disposed on the bottom end plate of the second casing 30, and may also be disposed on the top of the side wall of the second casing 30, and extends into the cooling cavity 35 after penetrating the top of the side wall of the second casing 30.

Referring to fig. 6-8, in one embodiment, the first housing 20 includes a first enclosure 23 and a first end plate 24 mounted on the first enclosure 23. The second housing 30 includes a second enclosure 36 and a second end plate 37 mounted on the second enclosure 36. The second shroud 36 fits over the exterior of the first shroud 23. The first enclosing plate 23 and the second enclosing plate 36 form a cooling cavity 35. The first end plate 24, the second end plate 37 and the second enclosing plate 36 form the water storage chamber 31. Therefore, the first shell 20 and the second shell 30 are both formed by enclosing plates and end plates, and in the assembling process, the second enclosing plate 36 is sleeved outside the first enclosing plate 23, so that the assembly of the cooling cavity 35 and the water storage cavity 31 can be formed.

It should be noted that both the water inlet pipe 32 and the water outlet pipe 33 can be arranged on the second enclosing plate 36; may also be provided on the second end plate 37; of course, the inlet pipe 32 could also be provided on the second enclosing plate 36, the outlet pipe 33 on the second end plate 37, etc. Meanwhile, the second mounting hole 34 is provided on the second end plate 37, and the first mounting hole 22 is provided on the first end plate 24.

Optionally, the first end plate 24 is connected to the first enclosing plate 23 by bolting, clamping, welding, integral molding, or the like. Meanwhile, the second end plate 37 is connected to the second enclosing plate 36 by bolts, clamping, welding, or integrally molding. Wherein, the integrated molding mode can adopt the processes of extrusion, casting, press fitting, injection molding and the like.

Referring to fig. 6 to 8, specifically, the second end plate 37 is provided with a folded edge, the folded edge is disposed along the edge of the second end plate 37, and the folded edge is attached to the second enclosing plate 36, so that the combined area between the second end plate 37 and the second enclosing plate 36 is increased by the folded edge in the process of assembling the second shell 30, and the overall structural strength of the second shell 30 is improved. Meanwhile, the flanging is also beneficial to improving the sealing performance between the second end plate 37 and the second enclosing plate 36. Of course, in order to further improve the sealing performance of the second housing 30, a sealing material may be provided between the folded edge and the second enclosing plate 36, such as: and arranging materials such as sealant, sealing rubber, waterproof adhesive tape and the like.

Further, the first surrounding plate 23 is provided with a first flange 231. The second collar 36 is provided with a second flange 361. When the second surrounding plate 36 is sleeved outside the first surrounding plate 23, the second turned-over edge 361 abuts against the first turned-over edge 231, so that the first shell 20 and the second shell 30 are in sealing fit, and the cooling cavity 35 is ensured to have a good sealing effect.

Of course, in other embodiments, only the first flange 23 is provided with the first flange 231, and when the second flange 36 is sleeved outside the first flange 23, one end of the second flange 36 abuts against the first flange 231; or, the first enclosing plate 23 is not provided with the first flanging 231, the second enclosing plate 36 is provided with a flanging which is turned inwards, and when the second enclosing plate 36 is sleeved outside the first enclosing plate 23, the flanging is abutted against the side surface of the first enclosing plate 23.

Referring to fig. 6 to 8, further, the outer diameters of the first partition plate 11 and the second partition plate 12 are close to the inner diameter of the second enclosing plate 36, so that the spoiler 10a and the partition member, the first partition plate 11 and the second partition plate 12, and the second enclosing plate 36, which are adjacently disposed, may form a relatively good sealed split cavity 311.

Referring to fig. 6 and 10, fig. 10 is a schematic structural diagram of a support member 50 in a tube type heat exchanger according to an embodiment of the invention. In one embodiment, the tube type heat exchanger further comprises a support 50 arranged within the second shell 30. The first partition plate 11 is fixedly installed on the supporting member 50. In this way, the support member 50 supports at least two first separating plates 11, and can prevent the first separating plates 11 from moving up and down along the height direction of the second casing 30, thereby ensuring that the interval between two adjacent first separating plates 11 is constant; in addition, in the installation process, the first partition plate 11 may be directly installed on the supporting member 50 and then installed in the second housing 30 together, so that it is not necessary to separately fix the first partition plate 11 to the side wall of the second housing 30, thereby simplifying the assembly operation and improving the production efficiency. It is needless to say that the support member 50 is omitted and the first partition plate 11 is directly installed in the second housing 30, which is not limited herein.

Referring to fig. 1, 4 and 10, in one embodiment, at least two first engaging slots 51 are formed on the supporting member 50, and second engaging slots 117 engaged with the first engaging slots 51 are formed on the edges of the first separating plate 11 and the second separating plate 12. Therefore, on one hand, the first partition plate 11 and the second partition plate 12 are both arranged on the support piece 50 in a clamping manner, so that the installation operation is relatively quick; on the other hand, after the first partition plate 11 and the second partition plate 12 are installed on the supporting member 50, the supporting member 50 is located in the second engaging groove 117, so that the supporting member 50 does not protrude to the region beyond the edge of the first partition plate 11, that is, the edge of the first partition plate 11 still contacts with the side wall of the second housing 30, and is not affected by the supporting member 50. It is understood that the first partition plate 11 is not limited to be clamped on the supporting member 50, and can be fixed on the supporting member 50 by welding, riveting, bonding, screwing, etc.

Referring to fig. 1, 4 and 10, in an embodiment, the supporting members 50 are more than two and are disposed in the second housing 30 at intervals, the second engaging grooves 117 are more than two, and the more than two second engaging grooves 117 are disposed in one-to-one correspondence with the more than two first engaging grooves 51 of the supporting members 50. The wall of the first engaging groove 51 is provided with a first protrusion 511, the first partition plate 11 and the second partition plate 12 are both provided with a first engaging hole 118 corresponding to the first protrusion 511, and the first protrusion 511 is engaged with and fixed in the first engaging hole 118. Thus, on one hand, the first partition plate 11 and the second partition plate 12 are supported and fixed by the two or more supporting members 50, so that the first partition plate 11 and the second partition plate 12 can be stably installed in the second housing 30; on the other hand, after the first partition plate 11 and the second partition plate 12 are mounted on the supporting member 50, the first protrusion 511 is inserted into the first engaging hole 118 to play a positioning role, so that the supporting member 50 is prevented from moving along the radial direction of the first partition plate 11 and the second partition plate 12, and the first partition plate 11 and the second partition plate 12 can be mounted on the supporting member 50 more stably.

In one embodiment, the support 50 is further provided with a positioning block 52 and a positioning end 53. The positioning block 52 abuts against the first end plate 24 of the first housing 20, and the positioning end 53 abuts against the second end plate 37 of the second housing 30. Thus, the supporting member 50 will not slide up and down, and the first partition plate 11 and the second partition plate 12 will be fixed relatively in the water storage chamber 31 and will not slide up and down.

Referring to fig. 6, 7, 10 and 11, fig. 11 is a schematic structural diagram of a flow equalizing ring 60 in a tube heat exchanger according to an embodiment of the present invention. In one embodiment, the tube heat exchanger further includes a flow equalizing ring 60 disposed within the second shell 30 and around the first shell 20. The flow equalizing ring 60 is provided with at least two flow equalizing holes 61, and the cooling cavity 35 is communicated with the water storage cavity 31 through the flow equalizing holes 61. At least one third clamping groove 54 is formed on the supporting member 50, and a fourth clamping groove 64 which is in clamping fit with the third clamping groove 54 is formed on the edge of the flow-equalizing ring 60.

Therefore, when water flows into the water storage cavity 31, the water flow is blocked by the flow equalizing ring 60, so that the water flow flows along the surface of the flow equalizing ring 60 and flows into the cooling cavity 35 from at least two flow equalizing holes 61, the water flow flowing into the cooling cavity 35 is uniformly dispersed, and the water in the water storage cavity 31 is fully mixed with the water in the cooling cavity 35.

Further, a second protrusion 541 is disposed on a wall of the third engaging groove 54, a second engaging hole 65 corresponding to the second protrusion 541 is disposed on the flow-equalizing ring 60, and the second protrusion 541 is engaged and fixed in the second engaging hole 65.

Furthermore, at least two flow equalizing holes 61 are uniformly arranged around the periphery of the first housing 20 at equal intervals, so that the dispersion degree of the water flow is increased, and the uniform mixing of the water flow in the cooling cavity 35 is further ensured.

Specifically, the flow-equalizing ring 60 has a circular ring structure, the shape of the inner wall of the flow-equalizing ring 60 is adapted to the outer wall of the first enclosing plate 23 of the first casing 20, and the shape of the outer wall of the flow-equalizing ring 60 is adapted to the inner wall of the second enclosing plate 36 of the second casing 30.

Alternatively, the flow equalizing ring 60 is not limited to be fixedly installed on the supporting member 50, but the connection manner between the first casing 20 and the second casing 30 is clamping, welding, bolting, pinning, etc., for example, and is not limited herein.
