Description
Technical field
The present invention relates to air-conditioning technical fields, more particularly to a kind of pipe clamp and heat exchanger.
Background technique
For commercial shell-and-tube heat exchanger because volume is big, heat exchanger tube is longer, and when unit is run heat exchanger tube by alternation gas shock,
Therefore setting support plate supports heat exchanger tube.For convenience of poling, tube sheet and heat exchanger tube preset clearance, but the presence in gap to grow
Phase is in the heat exchanger tube under micro-vibration state there are the risk of abrasion, in existing unit using welding, to paste swollen and installation slow
Three kinds of methods of object are rushed to eliminate this gap.
Welding takes time and effort, and is only used for the extremely special shell-and-tube heat exchanger of operating condition.Paste swollen, it is excessively high that there are costs
The problems such as, such as consume tube expander.Cushion is installed since its is low in cost, quality is stablized, now constantly by manufacturer
Attention, but install cushion there is also following disadvantages: there are about light pipe segments to sacrifice heat exchange area at support for heat exchanger tube；
The heat exchanger tube heat exchange property of cushion covering is lower, there is the space further increased；Installation is excessively secured, is not easy to remove dimension
Shield；Higher cost still has the space of optimization.

Specific embodiment
As shown in Figure 1, the pipe clamp proposed in the embodiment of the present invention, pipe clamp 20 is ring-shaped piece, can use metal or plastics
It is made, preferably plastic material, metalwork can be manufactured by metal plate punching, and plastic part is then using injection molding manufacture.
Pipe clamp 20 puts on heat exchanger tube 10 and is set between heat exchanger tube 10 and supporting element (being not drawn into figure), sets on pipe clamp 20
There is the radiator structure between heat exchanger tube 10 and supporting element, by the way that radiator structure is arranged, reduces the obstruction of exchange heat pipe, guarantee
Heat exchanger can be carried out effectively heat exchange when operation, and in the case where not reducing product strength, utmostly
Saving material.
Supporting element is tube sheet.
As shown in Figures 2 and 3, pipe clamp includes main part 21 and the interconnecting piece 22 set on axial one end of main part 21, master
Body portion 21 and interconnecting piece 22 are integrally formed.Radiator structure is set on main part 21, and supporting element covers on main part 21.Main part 21
The both ends axial along it are first end and second end, and interconnecting piece 22 is third end and the 4th end, main part along its axial both ends
21 second end is connect with the third end of interconnecting piece 22.
The diameter of interconnecting piece 22 is gradually reduced outward from axial one end of main part 21, i.e. the diameter of interconnecting piece 22 is from connection
The third end in portion 22 is gradually reduced to the 4th end, forms contraction mouth, easy disassembly.
As shown in Figures 2 and 3, in the present embodiment, radiator structure is multiple heat release holes 211, and multiple heat release holes 211 are divided into more
Group heat release hole group, the multiple groups heat release hole group circumferentially uniform intervals, the heat release hole 211 in every group of heat release hole group form " W " font.
As shown in figure 4,211 diameter of heat release hole is d, 6mm >=d >=1mm, preferably d are 2mm.It is adjacent in every group of heat release hole group
Spacing between two heat release holes 211 is b, and 10mm >=b >=2mm, preferably b are 5mm.Heat release hole not only increases heat exchange efficiency,
Stress of the pipe clamp when shrinking is reduced simultaneously to concentrate, and the risk of corrosion is brought so as to avoid the aging of accelerating tube card material.
As shown in Figures 2 and 3, circumferentially uniform intervals are equipped with multiple notches 221 on interconnecting piece 22, each notch 221
The part opposite with the open end of each notch 221 is necking end, and necking end is arc section 222, by the way that necking end to be arranged
At arc section, compared to conventional triangle necking end, when the pipe clamp installation of circular arc necking end effective solution is shunk, stress collection
In in the wedge angle the problem of.
In the present embodiment, each notch 221 is V-shaped, and the tip of v-notch is necking end.
On the outer surface of the end of the axial other end (i.e. first segment) of main part 21 circumferentially uniform intervals be equipped with it is multiple
Protrusion 212, can further decrease the problems in pipe clamp stress collection, the contraction of pipe clamp when facilitating installation.
As shown in figure 4, multiple raised 212 form discontinuous snap ring (i.e. the positioning ring of pipe clamp), snap ring is along main part axis
To with a thickness of e, 3mm >=e >=1mm, preferably e are 2mm.Two neighboring raised the distance between 212 be c, 5mm >=c >=1mm,
It is preferred that c is 3mm.For positioning snap ring, the height of the prominent main part outer surface of snap ring is f, and 3mm >=f >=1mm, preferably f are 1mm.
As shown in figure 5, on the outer surface of interconnecting piece 22 circumferentially uniform intervals be equipped with it is multiple be used for anti-skidding first boss
223.When installation, first boss 223 can (heat exchanger be at runtime in most cases for longitudinal vibration with the smallest power fixing clasp
It is dynamic, the structure will not be loosened).On the outer surface of interconnecting piece 22 circumferentially uniform intervals be equipped with it is multiple for the second convex of anti-failure
Platform 224, and first boss 223, second boss 224 from axial one end of main part outward (i.e. the third end of interconnecting piece 22 to
On the direction at the 4th end) it sets gradually.Second boss 224 can play secondary fixation when first boss 223 fails
Effect, improves the stability of snap ring.
First boss 223 and second boss 224 are semicolumn boss, and the length of semicolumn boss is g, and 6mm >=g >=
3mm, preferably g are 4mm, and the radius of semicolumn boss is h, and 4mm >=h >=1mm, preferably h are 2mm.
First boss and second boss may be trapezoid boss or triangle boss
The present invention also provides a kind of heat exchangers, including above-mentioned pipe clamp.
Above specific embodiment is only to the design illustrated the present invention, and those skilled in the art are in this hair
Various deformation and variation can be made under bright design, these deformations and variation are included within protection scope of the present invention.
