Exchange the stability of strutting system of heat pipe 20.
Alternatively, column attachment structure 34 is hollow endless tube, the first support beam 32 and the axial first end of hollow endless tube
Connection, the second support beam 33 are connected with the second axial end of hollow endless tube.So, support damping portion 30 edge is effectively increased
The thickness of heat exchanger axial direction, the structural strength of support damping portion 30 is improved, and column attachment structure 34 is using hollow
Endless tube is made, and hollow endless tube is easy to draw materials, and can so greatly reduce the processing and manufacturing cost of support damping portion 30, and raising is changed
The economic performance of hot device.
Alternatively, the first support beam 32 and the axial first end of hollow endless tube are welded, the second support beam 33 and cavity ring
Axial the second end welding of pipe.
As shown in Figures 2 and 3, support damping portion 30 also includes periphery beam 35, and periphery beam 35 has an installation region, first
The support support beam 33 of beam 32 and second is arranged in installation region.So, it is easy to support damping portion 30 to be installed to by periphery beam 35
In the heat exchanging chamber 11 of housing 10, periphery beam 35 with contour shape be adapted with the shape of cross section of housing 10, and support damping
After portion 30 is assembled in heat exchanging chamber 11, installation gap is left between the inwall of periphery beam 35 and housing 10.
Alternatively, in order to improve the first support beam 32 and the connective stability of periphery beam 35, support damping portion 30 is ensured
Structural strength, the both ends of the first support beam 32 are connected with periphery beam 35；Similarly, the second support beam 33 and periphery beam 35 are improved
Connective stability, ensure support damping portion 30 structural strength, the both ends of the second support beam 33 are connected with periphery beam 35.
Alternatively, support damping portion 30 plate-like, support damping portion 30 to be multiple, it is multiple to support damping portion 30 along heat exchanging chamber
11 axially spaced-apart is set.So, between multiple support damping portion 30 can play along the axial direction exchange heat pipe 20 of heat exchanger tube 20
Every ground supporting role, the stability of strutting system for exchanging heat pipe 20 is further increased.
It should be noted that multiple support damping portion 30 can use as the deflection plate of heat exchanger, medium is in heat exchanging chamber
Bafflings are carried out in 11 along multiple support damping portion 30 successively, the haul distance of the medium just shell side as heat exchanger.Support damping
Portion 30 can effectively improve the heat transfer effect of heat exchanger, make compared to support damping portion 30 is replaced with same amount of deflection plate
With heat exchanger overall heat-transfer coefficient under equal pressure drop can improve 50%.
As shown in figure 1, heat exchanger also includes two tube sheets 40, tube sheet 40 is arranged in heat exchanging chamber 11, and more heat exchanger tubes
20 are separately positioned between two tube sheets 40.Wherein, two tube sheets 40 are respectively fixed tube sheet and floating tubesheet.
Alternatively, in one alternative embodiment (not shown) of the utility model, heat exchanger also includes pipe joint, heat exchanger tube
20 both ends are respectively arranged with a pipe joint, and heat exchanger tube 20 is connected by pipe joint with tube sheet 40.
Alternatively, in an alternative embodiment (not shown) of the present utility model, heat exchanger also includes multiple deflection plates,
Multiple deflection plates are disposed in heat exchanging chamber 11 and between two tube sheets 40, and support damping portion 30 is selectively disposed in
Between the adjacent deflection plate of any two.
As can be seen from the above description, the utility model the above embodiments realize following technique effect：
Heat exchanger of the present utility model overcome the service life short life of heat exchanger of the prior art, energy consumption it is big and
The problem of the defects of easily cracked.Heat exchanger of the present utility model effectively reduces the vibration of heat exchanger tube, so that tube sheet institute
It is less than the critical threshold value that stress corrosion occurs by the algebraically stacking value of stress, so as to effectively reduce tube sheet, heat exchanger tube or pipe
The cracked risk of joint, ensure that the pacifying of heat exchanger, surely, long, full, excellent work production.
It should be noted that term used herein above is merely to describe embodiment, and be not intended to restricted root
According to the illustrative embodiments of the application.As used herein, unless the context clearly indicates otherwise, otherwise singulative
It is also intended to include plural form, additionally, it should be understood that, when in this manual using term "comprising" and/or " bag
Include " when, it indicates existing characteristics, step, work, device, component and/or combinations thereof.
It should be noted that term " first " in the description and claims of this application and above-mentioned accompanying drawing, "
