Abstract
The utility model discloses a parallel flow type heat exchanger with a novel equal allocation structure, which comprises a plurality of micro channel heat exchange flat tubes. Side plates are arranged on the outer sides of the micro channel heat exchange flat tubes at upper and lower edges uniformly; one end of the micro channel heat exchange flat tube is connected on a liquid distribution tube, and the other end is connected on a liquid collecting tube; an equal allocation tube is longitudinally arranged in the liquid distribution tube; a plurality of baffles are laterally arranged in the liquid distribution tube to divide a cavity of the liquid distribution tube into a plurality of slow flow cavities; and a plurality of overflow holes are formed in the wall of the equal allocation tube in the slow flow cavity. The baffles are reasonably utilized for dividing the cavity of the liquid distribution tube into a plurality of slow flow cavities in different lengths according to the flow direction of medium, and different quantities of overflow holes are formed in the walls of the equal allocation tubes in all the slow flow cavities, therefore, the medium allocated to all the micro channel heat exchange flat tubes is equal, thus exerting the heat exchange effect of each micro channel heat exchange flat tube.
Description
Technical field
The utility model relates to a kind of parallel flow heat exchanger, specifically relates 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 vertically to be provided with equal pipe arrangement in separating tube, realizes the purpose of uniform distribution medium by 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 be subjected to gravity etc. to influence when flow slowly in the inner chamber of separating tube, cause medium pressure in equal pipe arrangement inconsistent, is difficult to realize the purpose of uniform distribution medium.
Summary of the invention
The utility model mainly is to solve 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 utility model is mainly solved by 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, described 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 described 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, described 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 described separating tube and equal pipe arrangement upper 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; described 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 utlity model has characteristics such as simple in structure, reasonable in design.
