Abstract
The invention discloses a novel parallel flow heat exchanger with a uniform distribution structure, which comprises a plurality of microchannel heat exchange flat pipes, wherein side plates are arranged on the outer sides of the microchannel heat exchange flat pipes on the upper edge and on the lower edge, one end of each microchannel heat exchange flat pipe is connected with a liquid distribution pipe, the other end of each microchannel heat exchange flat pipe is connected with a liquid collection pipe, uniform distribution pipes are arranged in the liquid distribution pipe longitudinally, and a plurality of partition boards are arranged in the liquid distribution pipe horizontally to divide the inner cavity of the liquid distribution pipe into a plurality of buffering chambers; and in the buffering chambers, the pipe walls of the uniform distribution pipes are provided with a plurality of overflow holes. In the invention, the inner cavity of the liquid distribution pipe is divided into the plurality of buffering chambers with different lengths reasonably by the partition boards according to the flow direction of a medium and the pipe wall of each uniform distribution pipe is provided with different numbers of overflow holes in each buffering chamber; and thus, the medium distributed to each microchannel heat exchange flat pipe is more uniform, and the heat exchange effect of each microchannel heat exchange flat pipe is fully played.
Description
Technical field
The present invention relates to a kind of parallel flow heat exchanger, specifically relate to a kind of parallel flow heat exchanger of novel uniform distribution structure.
Background technology
In the prior art, mostly parallel flow heat exchanger is in separating tube, vertically to be provided with equal pipe arrangement, realizes the purpose of uniform distribution medium through the micropore on the equal pipe arrangement tube wall.Such structure; Because still being communicated with up and down, the inner chamber of separating tube is integral; The medium that micropore on equal pipe arrangement tube walls overflows is easy to receive gravity etc. to influence when in the inner chamber of separating tube, flow slowly, cause medium pressure in equal pipe arrangement inconsistent, is difficult to realize the purpose of uniform distribution medium.
Summary of the invention
The present invention solves above-mentioned existing in prior technology technical problem, and a kind of parallel flow heat exchanger of novel uniform distribution structure is provided.
Above-mentioned technical problem of the present invention mainly is able to solve through following technical proposals: a kind of parallel flow heat exchanger of novel uniform distribution structure; Comprise some Thermal Performance of Micro Channels flat tubes; The Thermal Performance of Micro Channels flat tube outside of last lower limb is equipped with side plate; One end of Thermal Performance of Micro Channels flat tube is connected on the separating tube; The other end is connected on the collector tube, and said separating tube the inside vertically is provided with equal pipe arrangement, and the separating tube the inside laterally is provided with several dividing plates the inner chamber of separating tube is separated into several slow flow cavity; In the said slow flow cavity, all offer several spout holes on the tube wall of pipe arrangement.According to MEDIA FLOW to rationally utilizing dividing plate the inner chamber of separating tube to be separated into the slow flow cavity of several different lengths; On the tube wall of equal pipe arrangement, open the spout hole of different numbers in each slow flow cavity; Be that the medium that every Thermal Performance of Micro Channels flat tube distributes can be comparatively even like this, give full play to the heat exchange effect of every Thermal Performance of Micro Channels flat tube.
As preferably, said equal pipe arrangement is arranged to the micropassage type flat tube configuration, and all the spout hole on the pipe arrangement sidewall is connected with hole, microchannel on the equal pipe arrangement; Be provided with buffer chamber between the upper end plug of said separating tube and equal pipe arrangement port at this moment.Equal pipe arrangement is arranged to the micropassage type flat tube configuration; Medium before this in buffer chamber uniform distribution advance the micropassage type flat tube of equal pipe arrangement; Each slow flow cavity is advanced in spout hole uniform distribution on equal pipe arrangement sidewall again; Be that the medium that every Thermal Performance of Micro Channels flat tube distributes can be more even like this, give full play to the heat exchange effect of every Thermal Performance of Micro Channels flat tube.
As preferably; Said equal pipe arrangement lower end sealing and the lower end that is fixed on separating tube are beyond the Great Wall; Descend end plug no longer to stand the direct impact of high-pressure medium like this, help protecting down end plug and equal syndetons of pipe arrangement, also help protecting down the syndeton of side plate and equal pipe arrangement.
The present invention has characteristics such as simple in structure, reasonable in design.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 is an another kind of structural representation of the present invention;
