Technical field
This utility model relates to technical field of chemical, is specially a kind of chemical industry fluid heat exchanger.
Background technology
Heat exchanger is the equipment that the partial heat of hot fluid passes to cold flow body, makes fluid temperature (F.T.) reach technological process rule
The heat exchange equipment of fixed index, also known as heat exchanger.Heat exchanger kind is a lot, but according to the exchange of cold and hot fluid heat
Principle and mode substantially can divide three major types i.e.: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, wall-type heat exchange
Device application is at most.Heat exchanger is chemical industry, oil, power, food and the common apparatus of other many industrial departments, accounts for aborning
There is critical role.In Chemical Manufacture, heat exchanger can be applied as heater, cooler, condenser, vaporizer and reboiler etc.
More extensive.
In actual use, the fluid state of heat exchanger entrance is that air-liquid is biphase, due to gas, liquid to existing heat exchanger
The density difference of fluid is relatively big, can be produced air-liquid segregation phenomenon by action of gravity, particularly when header is vertically placed,
Fluid liquid can be caused to be gathered in the lower end of header, and the distribution causing fluid is uneven.It addition, prior art has flat tube length
Inconsistent multipaths heat exchanger, the flat tube that wherein length is longer may set directly as the demarcation strip of flow process, this demarcation strip
Put opening so that the cold-producing medium in first pass is guided second procedure.But, the header in single flow process is connected
The flat tube problem that yet suffers from cold-producing medium maldistribution.
Utility model content
The purpose of this utility model is to provide a kind of chemical industry fluid heat exchanger, to solve proposition in above-mentioned background technology
Problem.
For achieving the above object, this utility model following technical scheme of offer: a kind of chemical industry fluid heat exchanger, including distribution
Pipe, main header, communicating pipe and heat-exchanger rig, described distribution pipe is provided with control valve, and distribution Guan Yuzhu header activity is even
Connecing, described main header is provided with communicating pipe, main header and be provided with the first fin between communicating pipe, described communicating pipe is by convex
Go out portion, uncovered, heat-exchanger rig, the second fin and peristome to combine, described heat-exchanger rig by sealing member, U-shaped branched pipe, change
Hot hole and subset flow tube composition.
Preferably, described uncovered with protuberance compact siro spinning technology.
Preferably, described peristome and heat-exchanger rig seamless link.
Preferably, described subset flow tube be arranged above sealing member, the inside of subset flow tube is inserted with U-shaped branched pipe.
Preferably, described U-shaped branched pipe is provided with several heat exchanging holes.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, by control valve control
The fluid processed flow velocity in header, it is to avoid fluid is too much, distribution inequality, avoid fluid accumulation the communicating pipe of horizontally set
In the lower end of header, also increase the heat exchange area of heat exchanger so that it is it is higher that efficiency becomes, additionally arrange on communicating pipe
Heat-exchanger rig, is internally provided with structure, U-shaped branched pipe and the subset flow tube heat exchanging such as U-shaped branched pipe, heat exchanging holes and subset flow tube
Fluid shunts, and further the fluid needing heat exchange is carried out secondary heat exchange so that heat transfer effect is more preferable.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-3, a kind of embodiment that this utility model provides: a kind of chemical industry fluid heat exchanger, including distribution pipe
1, main header 3, communicating pipe 5 and heat-exchanger rig 8, distribution pipe 1 is provided with control valve 2, and distribution pipe 1 is movable with main header 3
Connecting, control valve 2 controls fluid flow velocity in main header 3, it is to avoid fluid is too much, distribution inequality, and main header 3 is pacified
Equipped with communicating pipe 5, main header 3 and be provided with the first fin 4 between communicating pipe 5, communicating pipe 5 is by protuberance 6, uncovered 7, heat exchange dress
Put the 8, second fin 9 and peristome 10 combine, communicating pipe 5 horizontally set, it is to avoid fluid accumulates in main header 3 times
End, also increases the heat exchange area of heat exchanger so that it is it is higher that efficiency becomes, uncovered 7 and protuberance 6 compact siro spinning technology, peristome 10
