Be deteriorated and vibration problem for the exchange capability of heat that is easy to appear after baffle plate is arranged in the prior art, inventor into
Gone particular study, discovery main reason is that, after baffle plate is arranged, the position in shell after baffle plate will appear stagnant area
Domain, the fluid in Stagnation zones cannot be replaced in time, therefore exchange capability of heat is deteriorated；Moreover, on fluid impact to baffle plate
VELOCITY DISTRIBUTION is uneven, and the distribution for acting on the power on baffle plate is also just uneven, will cause the vibration of baffle plate in this case,
To drive heat exchanger body vibration, the overall performance of heat exchanger is influenced.
Further study show that as shown in Figure 1, being provided only on baffle plate in the prior art for passing through heat exchanger tube
First through hole 21, other than first through hole 21, other positions are with the entity part for stopping fluid to pass through effect.These
Although entity part can guide fluid to change flow path, inventor has found that these entity parts are especially
It is to be easy to appear fluid stagnation region in the position close to baffle plate and the junction of shell, the fluid flowing in the region is slow
Slowly, therefore it is poor with the heat-exchange capacity of heat exchange tube fluid；Meanwhile exactly because the also presence of Stagnation zones, fluid flow rate
Unevenness easily causes baffling panel vibration.In order to overcome the problems, such as this, a kind of improved baffle plate of structure is inventor provided.
Shown in referring to figs. 2 and 3, in one embodiment of shell-and-tube heat exchanger provided by the invention, the heat exchanger packet
Shell 10, heat exchanger tube and baffle plate 20 are included, heat exchanger tube passes through shell 10, and baffle plate 20 is mounted in shell 10, and baffle plate 20 is used
In changing the fluid flow path in shell 10, baffle plate 20 is equipped with first through hole 21 and the second through-hole 22, and heat exchanger tube passes through the
One through-hole 21, the second through-hole 22 is adjacent to the junction of baffle plate 20 and shell 10, and the second through-hole 22 is for making to circulate in shell 10
Interior fluid passes through.
Circulation has first fluid in shell 10, and circulation has second fluid in heat exchanger tube, between first fluid and second fluid
Carry out heat exchange.
In the above-described embodiments, use is additionally provided with other than the first through hole 21 for passing through heat exchanger tube on baffle plate 20
In the second through-hole 22 for passing through the fluid circulated in shell 10, and the second through-hole 22 is adjacent to the company of baffle plate 20 and shell 10
Place is met, a part of fluid circulated in shell 10 in this way can be avoided by 22 flow further downstream of the second through-hole in baffling
The junction of plate 20 and shell 10 forms fluid stagnation region, influences the heat transfer effect of fluid here in heat exchanger tube；Simultaneously
VELOCITY DISTRIBUTION of the fluid on baffle plate 20 can also be made more uniform, the stress of baffle plate 20 is also relatively uniform, effectively avoids
Baffle plate 20 vibrates, and improves the overall performance of heat exchanger.
Specifically, after the second through-hole 22 is arranged in the position of neighbouring baffle plate 20 with the junction of shell 10, work as fluid
It, can be by the laminar fluid in the region when fluid passes through the second through-hole 22 to Stagnation zones after plate when impacting on baffle plate 20
Replace the heat transfer effect for improving the region.
As shown in Fig. 2, being equipped with multiple baffle plates 20, the first end and shell of baffle plate 20 along fluid flow direction in shell 10
Body 10 connects, and the second end of the separate first end of baffle plate 20 is hanging, and has gap 30 between second end and shell 10, and second
Through-hole 22 is positioned close to first end and the position far from second end.
Multiple baffle plates 20 arrange that one in two that is, adjacent baffle plates 20 is mounted on the upper of shell 10 alternatively up and down
On plate 11, another is mounted in the lower plate 12 of shell 10, is circulated in the intracorporal fluid of shell and is blocked on encountering baffle plate 20,
Downstream can only be flowed to by the gap 30 between the second end and shell 10 of baffle plate 20, therefore the intracorporal fluid of shell just forms
S-shaped glide path, can be enhanced heat transfer effect in this way.
The quantity of the second set through-hole 22 can be one or more on baffle plate 20.Multiple second through-holes 22 are along folding
The junction of flowing plate 20 and shell 10 is formed by connecting line and is arranged in rows, and can arrange multiple rows of.Moreover, as shown in figure 3, second
Through-hole 22 is arranged into the other end from one end along the length direction of baffle plate 20, more to eliminate Stagnation zones comprehensively and thoroughly.
In multiple baffle plates 20, total circulation area of the second set through-hole 22 can phase on each baffle plate 20
Together, it can also be different.The cross sectional shape of the second set through-hole 22 may be the same or different on each baffle plate 20.
Optionally, each baffle plate 20 is equipped with one or more second through-holes 22, the institute on the baffle plate 20 of upstream
The total circulation area for the second through-hole 22 being arranged is greater than total stream of set the second through-hole 22 on the baffle plate 20 in downstream
Logical area.Setting can increase the ability that Stagnation zones are eliminated positioned at the baffle plate 20 of upstream in this way, even if the fluid stream of upstream
It is fast very fast, the formation probability of Stagnation zones will not be increased.
In fluid flow rate in constant and faster situation, the lesser baffling of total circulation area of the second through-hole 22 can choose
Plate 20, to increase the choked flow effect of baffle plate 20；In the case where constant in fluid flow rate and relatively slow, the second through-hole 22 can choose
The biggish baffle plate 20 of total circulation area, with improve baffle plate 20 eliminate Stagnation zones ability.
On the direction from the first end of baffle plate 20 to second end, the width L1 in gap 30 is the width L2's of shell 10
1/10~2/5, for example, 1/10,1/5,3/10,2/5.If the width L1 in gap 30 is too small, it is obviously inclined to will lead to Stagnation zones
Greatly, heat transfer effect is bad；If the width L1 in gap 30 is excessive, the outer flow velocity of pipe can be made less than normal, heat transfer effect is also bad.
It along the distance L3 of fluid flow direction is shell 10 from the first of baffle plate 20 between two neighboring baffle plate 20
End is not less than 50mm to 1/3~1/2 of the width L2 on the direction of second end.If distance L3 is too small, will lead to outside pipe
Flow velocity is too fast, keeps the outer pressure drop of pipe excessive；If distance L3 is excessive, will lead to pipe, flow velocity is less than normal outside, and heat transfer effect is bad.
Baffle plate 20 with a thickness of 3mm~10mm, such as 5mm.
As shown in Fig. 3, Fig. 4 and Fig. 5, the section of the second through-hole 22 can be round, diamond shape or strip.It is flowed along fluid
Direction, the cross sectional shape of the second through-hole 22 can be with flexible choice on multiple baffle plates 20, such as can successively circle, diamond shape, length
Bar shaped, or circle, diamond shape, circle etc., specifically can be depending on fluid mobility status.
In the case where fluid flow is constant, if the flow velocity of inlet fluid is very fast, it is biggish such as that opening area may be selected
Baffle plate 20 shown in fig. 5 weakens Stagnation zones；If inlet velocity is not that quickly, folding as shown in figure 3 or 4 can be selected
Flowing plate 20.
As shown in figure 3, the section of the second through-hole 22 is circle, the radius R of the second through-hole 22 is 1mm~5mm, such as 3mm.
The distance between two adjacent second through-holes 22 are (including between two adjacent second through-holes 22 as shown in Figure 3
Lateral distance L4 and fore-and-aft distance L5) it is 3~8 times of radius R of the second through-hole 22, such as 3 times, 4 times, 5 times, 6 times, 7 times and 8
Times.
If the distance between two adjacent second through-holes 22 are too small, the arrangement of the second through-hole 22 is too close, then can weaken
The choked flow ability of baffle plate 20, reduces heat transfer effect, and simultaneous processing is relatively difficult；If between two adjacent second through-holes 22
Distance is too big, and the arrangement of the second through-hole 22 is too sparse, then can weaken the ability that baffle plate 20 eliminates Stagnation zones.
The distance between the second nearest through-hole 22 of edge apart from baffle plate 20 and the edge of baffle plate 20 (including as schemed
Lateral distance L6 and fore-and-aft distance L7 between second through-hole 22 and the edge of baffle plate 20 shown in 3) it is logical not less than second
1.5 times of the radius in hole 22.
If edge of second through-hole 22 apart from baffle plate 20 is too close, difficulty of processing can be improved；If the second through-hole 22
Edge apart from baffle plate 20 is too far, then can not thoroughly eliminate Stagnation zones.
It should be noted that " fluid flow direction " herein refers to the direction as shown in arrow L in Fig. 2, it is macro
The substantially circulating direction of fluid in sight is not specific that is, from the fluid inlet of shell to the direction of the fluid outlet of shell
The S-shaped glide path of fluid in embodiment.
Pass through the explanation of multiple embodiments to shell-and-tube heat exchanger of the present invention, it can be seen that shell-and-tube heat exchanger of the present invention
Embodiment guides Stagnation zones fluid to redistribute by aperture reasonable on board-like baffle plate, has reached and has improved changing for heat exchanger
The effect of thermal energy power；Meanwhile second through-hole there is decompression function, help to weaken because change in fluid pressure is excessive and it is uneven due to
Caused vibration.
Based on above-mentioned shell-and-tube heat exchanger, the present invention also proposes a kind of air-conditioner set, which includes above-mentioned
Shell-and-tube heat exchanger.In addition to air-conditioner set, shell-and-tube heat exchanger provided by the invention can be used for other and need what is exchanged heat to set
In standby.
