Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of header structure of heat exchanger is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of header structure of heat exchanger, one side of header is provided with the interface of the heat radiating flat tube that is used to peg graft, described heat radiating flat tube is plugged in the header by interface, two headers about the microchannel of heat radiating flat tube is communicated with, relative side at described interface in the inner chamber of header is provided with the location liner, the inner face of heat radiating flat tube supports on the locating surface that is located at the location liner, the outside of described location liner is provided with some ribs, the lateral surface soldering of laying-in rib is fixed on the inner surface of header in the location, space between the adjacent rib constitutes medium and distributes the microchannel, the sidewall of location liner is provided with some media and distributes through hole, medium distributes through hole and medium to distribute the microchannel to be connected, the appropriate design medium distributes the number of through hole, can be so that medium distributes each flat tube of flowing through comparatively uniformly.
As preferably, some ribs in the described location liner outside can be that all whole from top to bottom the perforation is provided with, can be between across intermittently being provided with from top to bottom, or all intermittently be provided with from top to bottom.
As preferably, also be provided with dividing plate in the described header, the cavity that dividing plate will be located between liner and the header is separated into some capacitors, medium in conjunction with appropriate design distributed the through hole number before this, make medium be assigned to comparatively uniformly in each capacitor, rate-of flow is allocated to some aliquots by one large, further medium is assigned in each flat tube uniformly by each capacitor again behind the unhurried current, can realize the purpose of uniform distribution medium to the full extent, give full play to the radiating effect of all flat tubes, improve the heat exchange efficiency of heat exchanger.
The utility model improves the location liner in the header inner chamber, makes it to have the function of location flat tube and uniform distribution medium, and the location uniformity of flat tube is good, has also improved the compressive resistance of header; Utilize the medium that the space constitutes between the adjacent rib in the liner outside, location to distribute the microchannel besides, can make the medium of MEDIA FLOW on the liner sidewall of location distribute through hole to enter into comparatively uniformly and be separated into some capacitors by dividing plate, medium is flowed through in each flat tube by uniform distribution once more in capacitor, be beneficial to give full play to the radiating effect of all flat tubes, improve the heat exchange efficiency of heat exchanger; The 3rd utilizes the lateral surface of rib will locate the liner soldering is fixed on the inner surface of header, and scolder unnecessary after the fusion can emit smoothly via the space between rib, reduces the possibility of its corrode product, helps prolonging the service life of product.Integral body has characteristics such as simple in structure, reasonable in design.
