Description
Technical field
The utility model relates to micro-channel heat exchanger technology.
Background technology
As shown in Figure 1, for the micro-channel heat exchanger of routine, comprise two headers 1 be arranged in parallel and the rows of flat pipes 2 be installed between two headers, outside outermost flat tube, be provided with side plate 3, wing 4 in being provided with between adjacent two flat tubes, is provided with limit wing 5 between outermost flat tube and side plate.Limit wing and fin are not distinguished by this conventional micro-channel heat exchanger, and namely wing specification used in limit is identical with fin specification, and intensity is consistent.
The existing processing technology of microchannel full aluminium heater core body, cross stokehold generally to need to tie up clamping with fixture (or sheet iron strip), and the linear expansion coefficient of aluminium alloy differs comparatively large with the linear expansion coefficient of iron wire (or sheet iron strip), when therefore heating in stove, larger internal stress can be produced.At a higher temperature, intensity reduces fin greatly, and rigidity is too large, and the stress at this moment caused in fixture (or sheet iron strip) heat expansion forces lower meeting to make the bending lodging of limit wing, has a strong impact on presentation quality.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of micro-channel heat exchanger, avoids limit wing to occur bending lodging phenomenon.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of micro-channel heat exchanger, comprise two headers be arranged in parallel and the rows of flat pipes be installed between two headers, side plate is provided with outside outermost flat tube, wing in being provided with between adjacent two flat tubes, between outermost flat tube and side plate, be provided with limit wing, described limit wing is provided with the intensity enhancing structure making limit wing intensity be greater than middle wing intensity.
Preferably, a pitch of fins for described limit wing is less than a pitch of fins for middle wing.
Preferably, the thickness of described limit wing is greater than the thickness of middle wing.
Preferably, the wave height of described limit wing is less than the wave height of middle wing.
Preferably, described limit wing adopts the rigidity of material to be greater than the rigidity of middle wing employing material.
Preferably, the middle wing of adjacent side wing also arranges described intensity enhancing structure.
The limit wing of micro-channel heat exchanger and middle wing are distinguished by the utility model, the intensity of limit wing are strengthened, and make it be greater than the intensity of middle wing, thus the extruding force preventing product to be subject to exceed the pressure of permission, avoid the phenomenon occurring limit wing lodging.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of micro-channel heat exchanger in prior art;
Fig. 2 is the structural representation of micro-channel heat exchanger in embodiment 1;
Fig. 3 is the structural representation of micro-channel heat exchanger in embodiment 2;
Fig. 4 is the structural representation of micro-channel heat exchanger in embodiment 3.
Detailed description of the invention
As shown in Figures 2 to 4, micro-channel heat exchanger of the present utility model, specifically comprise two headers 1 be arranged in parallel and the rows of flat pipes 2 be installed between two headers 1, side plate 3 is provided with outside outermost flat tube 2, wing 4 in being provided with between adjacent two flat tubes 2, between outermost flat tube 2 and side plate 3, be provided with limit wing 5, this is the structure identical with conventional micro-channel heat exchanger.The limit wing 5 of micro-channel heat exchanger is distinguished with middle wing 4 by the utility model, and the intensity of limit wing strengthened, namely limit wing is provided with the intensity enhancing structure making limit wing intensity be greater than middle wing intensity.The intensity enhancing structure of limit wing is described below in conjunction with specific embodiment.
As shown in Figure 2, in embodiment 1, the parameter such as thickness, wave height, louver angle of limit wing 5 is all identical with middle wing 4, and uniquely unlike the intensity enhancing structure that limit wing is arranged, it reduces a pitch of fins for limit wing, makes a pitch of fins for limit wing be less than a pitch of fins for middle wing.
The reduction of a pitch of fins, adds the wave number of limit wing, stiffened edge wing intensity, overcomes the defect that the existing technique stress that fixture (or sheet iron strip) heat expansion causes in stove forces limit wing lodging, improves presentation quality.
As shown in Figure 3, in example 2, the parameter such as the pitch of waves, wave height, louver angle of limit wing 5 is all identical with middle wing 4, uniquely unlike the intensity enhancing structure that limit wing is arranged, increase the thickness of limit wing specifically, make the thickness of limit wing be greater than the thickness of middle wing.
The increase of thickness, increases limit wing intensity, overcomes the stress that iron wire (or sheet iron strip) heat expansion causes in stove and forces the diastrophic defect of limit wing, improves presentation quality.
As shown in Figure 4, in embodiment 3, the parameter such as thickness, a pitch of fins, louver angle of limit wing 5 is all identical with middle wing 4, uniquely unlike the intensity enhancing structure that limit wing is arranged, reduce the wave height of limit wing specifically, make the wave height of limit wing be less than the wave height of middle wing.
The reduction of limit wing wave height, substantially increases as deposited strength and the presentation quality of limit wing.Meanwhile, due to thickness and a pitch of fins constant, only reduce wave height, decrease limit wing cost.
The technical scheme that embodiment 4 adopts, the parameter such as thickness, a pitch of fins, louver angle of limit wing 5 is all identical with middle wing 4, unique different from the material that middle wing 4 adopts unlike limit wing 5, adopt the higher material of rigidity to do limit wing specifically, thus stiffened edge wing rigidity avoid limit wing lodging.
Above-mentioned several embodiment according to actual conditions, freely can combine mutually, forms new technical scheme.Such as, in a pitch of fins for limit wing is less than wing a pitch of fins while limit wing adopt the rigidity of material to be greater than in wing adopt the rigidity of material; In the thickness of limit wing is greater than wing thickness while limit wing adopt the rigidity of material to be greater than in wing adopt the rigidity of material; In the wave height of limit wing is less than wing wave height while limit wing adopt the rigidity of material to be greater than in wing adopt the rigidity of material.
In addition, the extruding force that the difference of product size is subject to is also different, therefore not only as above-described embodiment, can only strengthen the intensity of limit wing, when product be squeezed power larger, also one or a few wing in the wing of limit can be arranged the intensity enhancing structure identical with limit wing.
