Description
Technical field
The utility model relates to a kind of external-cooling type high-performance heat exchangers.
Background technique
The contact area when carrying out heat exchange is small with heat exchanger for existing water sealing stove, and heat exchange efficiency is low, unreliable, passes simultaneously
The heat exchanger of system is carrying out the problems such as heat exchange is that leakage, corrosion often occurs, to need to change part, significantly increases
Cost.
Summary of the invention
In view of the deficienciess of the prior art, the purpose of this utility model, which is that, provides a kind of external-cooling type high efficient heat exchanging
Device, cold wind enter from outer wall pipe, and hot wind comes out from inner tubal wall, and outer tube is normal temperature state, and the heat exchange of inner tube double-walled, heat exchange efficiency is high,
Securely and reliably.
To achieve the goals above, the technical solution adopted in the utility model is such that a kind of external-cooling type high efficient heat exchanging
Device, including outer tube, inner tube, base tube, the outer tube top is set to the top of base tube by upper sealing plate, outer pipe bottom passes through lower envelope
Plate is set to the lower part of base tube, offers air inlet on the outer tube wall of the outer tube；Said inner tube be set to outer tube and base tube it
Between, said inner tube bottom is set on lower sealing plate；Air outlet is offered on the inner tubal wall of said inner tube, which runs through outer tube
Outer tube wall extend outwardly.
As a preferred embodiment, the outer tube, inner tube, base tube coaxial arrangement.
As a preferred embodiment, the air inlet is set to the lower part of outer tube, and the air outlet is set under inner tube
Portion, the air inlet and air outlet are symmetrical arranged according to central axis.
As a preferred embodiment, the base tube is made of heat-resisting steel sheet and plate.
As a preferred embodiment, said inner tube and outer tube are made of carbon steel.
As a preferred embodiment, the upper sealing plate and lower sealing plate are sealing flange.
Compared with prior art, the utility model has the beneficial effects that the cold wind of the utility model enters from outer wall pipe, hot wind
It is come out from inner tubal wall, outer tube is normal temperature state, and the heat exchange of inner tube double-walled, heat exchange efficiency is high, securely and reliably.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram in A-A direction of Fig. 1 in the utility model.
Specific embodiment
The utility model is further described combined with specific embodiments below.Following embodiment is only used for clearly
Illustrate the technical solution of the utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
Embodiment:
As shown in Figure 1 and 2, a kind of external-cooling type high-performance heat exchanger, including outer tube 1, inner tube 2, base tube 3,1 top of outer tube
The lower part that the top of base tube 3,1 bottom of outer tube are set to by lower sealing plate 5 base tube 3, the outer tube 1 are set to by upper sealing plate 4
Outer tube wall on offer air inlet 6；Said inner tube 2 is set between outer tube 1 and base tube 3, and 2 bottom of said inner tube is set to down
On sealing plate 5；Air outlet 7 is offered on the inner tubal wall of said inner tube 2, which extends outwardly through the outer tube wall of outer tube 1.
Specifically, the outer tube 1, inner tube 2, base tube 3 are coaxially disposed, heat exchange is uniform.
Specifically, the air inlet 6 is set to the lower part of outer tube 1, the air outlet 7 is set to the lower part of inner tube 2, described
Air inlet 6 and air outlet 7 are symmetrical arranged according to central axis.Further, cold wind enters outer tube 1 and inner tube 2 from air inlet 6
Between when exchanged heat in advance, carry out secondary heat exchange until cold wind enters between inner tube 2 and base tube 3, then hot wind is from outlet air
Mouth 7 comes out, and outer tube 1 is normal temperature state, and the heat exchange of 2 double-walled of inner tube, heat exchange efficiency is high, securely and reliably.
Specifically, the base tube 3 is made of heat-resisting steel sheet and plate, there is good heat resistance, inoxidizability, corrosion resistance.
Specifically, said inner tube 2 is made with outer tube 1 of carbon steel, at low cost, hardness is moderate with flexibility.
Specifically, the upper sealing plate 4 and lower sealing plate 5 are sealing flange.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
It also should be regarded as the protection scope of the utility model into deformation.
