Description
Technical field
The utility model belongs to heat-exchanger rig field, is related to heat-exchange system, and energy recycle device more particularly to one kind are new
Tubular heat exchanger.
Background technology
With deepening continuously for economic construction, the energy with it is environmentally friendly and sustainable in face of, it is desirable to existing equipment is significantly strong
Change, equipment gradually improves in terms of innovative and heavy duty detergent.Extensive industrial production will become history, with less equipment
The upper fine type industrial production of saving for obtaining bigger economic value has been arrived, so, the miniaturization of equipment, structure it is reasonable
Change, the brief plain clothes operationalization of industrial flow should be gradually taken seriously.
In terms of heat exchange, equipment that the carrying object that makes temperature higher imparts heat to the relatively low carrying object of another temperature,
As heat-exchange apparatus or heat exchanger, heat exchanger in terms of pre- recuperation of heat and comprehensive utilization of energy with extensive, have plenty of in order to
Allow carrying object to reduce temperature with proper storage or discharge, have plenty of to allow carrying object rise temperature with suitable burning or accelerate chemistry
Reaction.Because technological process is different, the effect of heat exchanger wherein is different, but general principle is approximate.
Heat exchanger can classify by action principle, also can classification by use.But the sorting technique most generally used is by heating
The shape and textural classification on surface.Wherein pipe heat exchanger is the most universal most succinct form of heat exchange, and its is easy to process, efficiency
Height, it is compact-sized many advantages, such as, be widely used in industry by people.It is civilian.The fields such as aviation.
Pipe heat exchanger in order that heat exchanger tube lateral fluid fully and heat exchanger outer surface contact, to increase the coefficient of heat transfer,
Central dividing plate can be installed on vertical tube axial direction, this central dividing plate makes fluid in heat exchanger chamber interior flow field from linear pattern stream
Field is changed into S types or serpentine flow, strengthens flow disturbance, enhances the convective heat-transfer coefficient of fluid, is fully sent out in fluid
While exhibition, adverse effect also is brought to heat exchange structure, because the semiclosed property of central dividing plate makes fluid forcibly changing route,
The resistance of air is also increased on certain angle, or reduces rate of air circulation when inlet and outlet pressure is identical, such case exists
Aggravate also the uneven homogenized situation of flow velocity in overall heat exchange structure, to be the great change of internal temperature field, and in deflection plate
Both sides often produce alluvial, and air themperature herein is higher, are more difficult to move, only can be with main serpentine channel
Heat exchange is realized, heat exchange efficiency is low, and about 40% area can not exchange heat, and thermal field is uneven after causing fluid heat transfer, and serious can also damage
Bad heat exchanger, in the prior art for the thermal field inside uniform heat exchange device, typically using rotary structure homogeneous (uniform) fluid, but
Rotary type heat exchanger refers to larger, composition complexity.
Utility model content
Purpose of utility model, the shortcomings that the utility model is directed to above-mentioned existing heat-exchanger rig, and provide a kind of new
Tubular heat exchanger, its can effective uniform inner thermal field, ensure two-fluid curvilinear motion in heat exchanger, that is, ensure that S-shaped is snakelike
Wriggle, in turn ensure that and be easy to radiate at alluvial.
Problem to be solved in the utility model is realized by following technical scheme：
A kind of new tubular heat exchanger is provided, it includes supporting shell, and multiple deflection plates, each folding are provided with supporting shell
The spacing of flowing plate is equal and staggers up and down successively, and being set up in supporting shell through deflection plate has more heat exchanger tubes, in each baffling
All be provided with plate it is multiple be used to discharge the through holes of pressure, on deflection plate along the radial direction of each heat exchanger tube all offer it is multiple uniformly
The heat exchanging holes of distribution.
Further, described through hole is round tube hole.
Further, the middle separated time of the line at the center per two adjacent heat exchanger tubes is mark line, on every mark line
At least offer two round tube holes.
Further, described round tube hole number is six, and two round tube holes are shared between every two adjacent heat exchanger tubes,
A round tube hole is shared between per three adjacent heat exchanger tubes.
Further, described through hole or be strip through-hole.
Further, described strip through-hole camber extension, along the periphery of each heat exchanger tube on corresponding deflection plate
All uniformly offer multiple strip through-holes.
The utility model has the advantage that for existing：
Eliminate in the both sides of central dividing plate, the larger stepped change that pressure field distribution occurs.Central dividing plate it
Between region in, pressure field distribution is more uniform.
Establishing path on the uneven both sides of pressure makes pressure be discharged on path, in Temperature Distribution field, in dividing plate
Low-pressure side generate high temperature because no fluid flows through.So after producing path at dividing plate, can because there is pressure trend
To force fluid distrbution speed to tend to homogenize, temperature field is had clear improvement, and localized hyperthermia, which sentences, to be substantially eliminated, in inlet flow
Measure it is constant in the case of outlet temperature risen, so heat exchange efficiency is correspondingly improved.
Because eliminating localized hyperthermia's problem, because the situation of high temperature corrosion aggravation is also improved accordingly.
S-shaped temperature transition curve is ensure that, using hyperbolic configuration form, can realize that straight line penetrates at deflection plate,
Sigmoid curve flow profile can be realized in the S-shaped cavity that dividing plate is formed, heat exchange efficiency is higher.
