Abstract
The invention relates to a double-channel heat exchanger core structure which comprises a pair of cover plates. The space between the two cover plates is divided by separation plates to form low-temperature air channels and high-temperature oil channels. The single air channels are adjacent to the cover plates and the double oil channels. The space between the two cover plates of a plate-fin heat exchanger is full of the single air channels and the double oil channels, and on the premise that the inner cavity volume and heat exchange performance of oil are not changed, the strength of inner channels is greatly improved, and the inner channels on the peripheries of the cover plates are overall protected. Meanwhile, E-shaped sealing strips are adopted as sealing strips of the single air channels, so that assembly cost is reduced, and assembly reasonability and brazing strength are further guaranteed.
Description
Technical field
The present invention relates to technical field of heat exchangers, especially a kind of Dual-channel type core structure of heat exchanger.
Background technology
Present stage, plate-fin heat exchanger existingly in compressor industry applied comparatively widely, but the larger heat exchanger of some profiles when designing because the large operating pressure of flow of heat transferring medium is high, again because the restriction of the device space makes product cannot do greatly, so the little resistance of medium of internal channel will be excessive, if but excessive talking path remitted its fury, the actual heat exchanger just do not reached required for equipment.
Summary of the invention
The applicant, for above-mentioned existing issue, is studied improvement, provides a kind of Dual-channel type core structure of heat exchanger, under the prerequisite that the cavity volume and heat exchange property that ensure oil are constant, substantially increases the intensity of internal channel.
The technical solution adopted in the present invention is as follows:
A kind of Dual-channel type core structure of heat exchanger, comprises a pair cover plate, between two cover plates, forms low wet passage and high temperature oil passage by baffle for separating, described single air flue layout adjacent with described cover plate, described pair of oil duct and the described pair of adjacent layout of oil duct.
Its further technical scheme is:
Described single air flue is a low wet passage, and described single air flue comprises the first fin, installs the first strip of paper used for sealing respectively at the two ends of described first fin;
Described pair of oil duct is two high temperature oil passages, and described pair of oil duct comprises two by baffle for separating second fin, installs the second strip of paper used for sealing respectively at the two ends of described second fin.
Have two depressed parts at described first strip of paper used for sealing near the side of the first fin, between two depressed parts, form protuberance.
Beneficial effect of the present invention is as follows:
The present invention is covered with the two oil duct of single air flue between the two cover plates of plate-fin heat exchanger; decrease external stress and concentrate the distortion infringement caused; protect cover plate periphery internal channel; the strip of paper used for sealing of single air flue adopts " E " shape strip of paper used for sealing simultaneously; not only reduce assembly cost, also assures that the reasonability of assembling and the intensity of soldering.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 and Figure 2, a kind of Dual-channel type core structure of heat exchanger, Dual-channel type core structure of heat exchanger, comprise a pair cover plate 1, low wet passage and high temperature oil passage is separated to form by dividing plate 4 between two cover plates 1, single air flue 2 layout adjacent with cover plate 1, single air flue 2 and two adjacent layout of oil duct 3.As shown in Figure 3, single air flue 2 is a low wet passage, and single air flue 2 comprises the first fin 24, installs the first strip of paper used for sealing 21 respectively at the two ends of the first fin 24.To have between two depressed parts, 22, two depressed parts 22 near the side of the first fin 24 at the first strip of paper used for sealing 31 and form protuberance 23.Depressed part 22 and protuberance 23 make the first strip of paper used for sealing 1 form " E " font near the side of the first fin 24.As shown in Figure 4, two oil duct 3 is two high temperature oil passages, and two oil duct 3 comprises two and separates the second fin 31 by dividing plate 4, installs the second strip of paper used for sealing 32 respectively at the two ends of the second fin 31.
The present invention is covered with the two oil duct of single air flue between the two cover plates of plate-fin heat exchanger, under the prerequisite that the cavity volume and heat exchange property that ensure oil are constant, substantially increase the intensity of internal channel, the strip of paper used for sealing of single air flue adopts " E " shape strip of paper used for sealing simultaneously, not only reduce assembly cost, also assures that the reasonability of assembling and the intensity of soldering.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to basic structure of the present invention, the present invention can do any type of amendment.
