Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in embodiment is clearly and completely described.Obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In describing the invention, it will be appreciated that, term " " center ", " transverse direction ", " longitudinal direction ", " front ", " afterwards ", " left side ", " right side ", " on ", D score, " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of the instruction such as " outward " are based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore limiting the scope of the invention can not be interpreted as.
As shown in Figure 1, be the structural representation of a heat exchanger of the present invention embodiment.This heat exchanger, comprise the first heat exchange unit, also comprise the second heat exchange unit, the internal circulation of described first heat exchange unit has cycle fluid, the outside circulation of described first heat exchange unit has the first heat transferring medium, the internal circulation of described second heat exchange unit has the second heat transferring medium, and described first heat exchange unit and described second heat exchange unit disposed adjacent to realize heat trnasfer, and then make described cycle fluid can carry out heat exchange with described first heat transferring medium and described second heat transferring medium respectively.
Heat exchanger in the present embodiment is on the basis of original first heat exchange unit, add the second heat exchange unit, first heat exchange unit and the second heat exchange unit disposed adjacent, make can carry out heat trnasfer between the cycle fluid in the first heat exchange unit and the second heat transferring medium in the second heat exchange unit, and first heat transferring medium that also circulated in the first heat exchange unit outside, therefore cycle fluid can carry out heat exchange with the first heat transferring medium and the second heat transferring medium respectively, thus the heat transfer effect of heat exchanger is strengthened greatly, improve heat exchange efficiency, realize making full use of of the energy, meet the various heat exchange demands in life and production practices.
In order to improve the heat transfer effect between the cycle fluid in the first heat exchange unit and the second heat transferring medium in the second heat exchange unit further, heat conduction structure is provided with, to carry out heat trnasfer by heat conducting mode between described first heat exchange unit and described second heat exchange unit.
The specific implementation form of above-mentioned heat conduction structure can have multiple choices, as long as can strengthen the heat transfer effect between the first heat exchange unit and the second heat exchange unit.Preferably, described heat conduction structure is fin 5.
About the shape of fin, also can select arrangement easily according to actual needs, preferably, described fin 5 is in undaform or V-type.Between the first heat exchange unit and the second heat exchange unit, described fin 5 can be continuous structure, namely arranges fin continuously, to realize larger area of dissipation; Also can be intermittent configuration, namely be spaced a distance between each fin, key area can be selected to carry out enhanced heat exchange, to save material and simplify fabrication schedule while guarantee radiating effect.
In addition, also circulated described first heat transferring medium in the outside of described second heat exchange unit and/or described heat conduction structure.The main purpose of this setting makes the second heat transferring medium in the second heat exchange unit and heat conduction structure itself also can carry out heat exchange with the first heat transferring medium, thus improve the radiating effect of the first heat exchange unit further.Certainly, the first heat transferring medium circulated in first heat transferring medium of the outside circulation of the second heat exchange unit and/or heat conduction structure and the first heat exchange unit outside all can select air, also all can select water, the two can also select different types of heat transferring medium respectively.
Multiple choices can be had for the specific constructive form of the first heat exchange unit and the second heat exchange unit in the various embodiments described above.Preferably, described first heat exchange unit comprises at least two first headers 1 and at least one first flat tube 2, at least two the first headers 1 described at least one first flat tube 2 described is plugged in, and forms the first circulation canal;
