Description
Technical field
The present invention relates to the technology of a kind of field of heat exchangers, a kind of U-shaped connector type parallel-flow evaporator.
Background technology
Microchannel U-shaped connector type parallel-flow evaporator is made up of flat tube, fin etc., has excellent heat exchange property.But
Cold-producing medium within common U-shaped connector type parallel-flow evaporator is two phase flow, and two phase flow is unstable, easily causes cold-producing medium
Distribution uneven, cause the hydraulic performance decline of whole vaporizer.
Summary of the invention
The distribution that the present invention is directed to the cold-producing medium that prior art causes due to collecting pipe structure is uneven, thus causes vaporizer
The problems such as degradation of heat exchange performance, propose a kind of U-shaped connector type parallel-flow evaporator, achieve cold-producing medium by U-shaped union joint
From the directly transfer of a upper flat tube to next flat tube, it is to avoid cold-producing medium distribution inequality, improve the heat exchange efficiency of vaporizer.
The present invention is achieved by the following technical solutions:
The present invention includes: U-shaped union joint and include influent stream distribution pipe and go out the header of flow point pipe arrangement, wherein:
Influent stream distribution pipe and go out flow point pipe arrangement and be connected with some porous flat pipes respectively, the porous flat pipe being connected with influent stream distribution pipe and with go out to flow
The porous flat pipe that distribution pipe is connected is connected by union joint one_to_one corresponding.
Described union joint is bent to form by flat tube.
One end of described influent stream distribution pipe is connected with inlet tube and outlet respectively with the one end going out flow point pipe arrangement.
Being provided with the fixed plate for fixing support porous flat pipe between described union joint and header, porous flat pipe wears
In fixed plate.
It is provided with fin between described porous flat pipe.
Described influent stream distribution pipe and the cross section going out flow point pipe arrangement are all rectangle.

Detailed description of the invention
Elaborating embodiments of the invention below, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following enforcement
Example.
Embodiment 1
As it is shown in figure 1, the present embodiment includes: some porous flat pipes 4, U-shaped union joint 5 and by influent stream distribution pipe 301 and going out
The header 3 of flow point pipe arrangement 302 composition, wherein: influent stream distribution pipe 301 and go out flow point pipe arrangement 302 respectively with porous flat pipe 4 one end
Be connected, the other end of porous flat pipe 4 that is connected with influent stream distribution pipe 301 and with go out porous flat pipe 4 that flow point pipe arrangement 302 is connected
The other end is connected by union joint 5 one_to_one corresponding.
As in figure 2 it is shown, described header 3 includes influent stream distribution pipe 301 and goes out flow point pipe arrangement 302.Influent stream distribution pipe 301
Being rectangle with the cross section going out flow point pipe arrangement 302, its upper face has the slotted eye identical with porous flat pipe 4 cross section.
As it is shown on figure 3, be laid with some perforates successively in described fixed plate 6.This hole shape is horizontal with porous flat pipe 4
Cross sectional shape is identical, is sheathed on porous flat pipe 4 outside.This fixed plate 6 is arranged at the upper end of porous flat pipe 4, by porous flat pipe 4
It is arranged in perforate with union joint 5 connecting place, plays and seal and fixing effect.
As shown in Figure 4, the described slotted eye on influent stream distribution pipe 301 is uniformly distributed successively.Same, go out flow point pipe arrangement
Slotted eye on 302 is uniformly distributed the most successively.Described influent stream distribution pipe 301 and go out one end of flow point pipe arrangement 302 be connected with respectively into
Mouth pipe 1 and outlet 2.
As it is shown in figure 5, described union joint 5 is u-shaped, it is made up of flat tube bending, its two-port shape and porous flat pipe 4
Identical, and be connected with corresponding porous flat pipe 4.
As shown in figs. 6-7, described influent stream distribution pipe 301 and porous flat pipe 4 one_to_one corresponding gone out on flow point pipe arrangement 302,
The upper end of two corresponding porous flat pipes 4 is connected by union joint 5.The fin 7 for heat radiation it is provided with between described porous flat pipe 4.
Cold-producing medium from inlet tube 1 flow to influent stream distribution pipe 301, and after flow to union joint 5 through porous flat pipe 4, flowed to separately by union joint 5
One corresponding porous flat pipe 4, eventually flows into out flow point pipe arrangement 302, completes circulation.
Compared with prior art, the present invention achieves cold-producing medium from a upper flat tube to next flat tube by U-shaped union joint
Directly transfer, it is to avoid cold-producing medium distribution inequality, improves the heat exchange efficiency of vaporizer.
