Abstract
The invention provides cooling fins of a heat exchanger. The cooling fins are characterized in that the cooling fins are corrugated cooling fins; tops and roots of the corrugated cooling fins are circular arcs; and grooves and bulges are arranged on the surfaces of the corrugated cooling fins. The cooling fins have the following beneficial effects that: the sharp angles of the tops and roots of the cooling fins in the heat exchanger are changed into circular arc shaped ends, so that the contact areas of the tops and roots of the cooling fins and upper and lower clapboards are increased, thus during brazing, the welding areas are enlarged and the structures are firmer; besides, by arranging the bulges and grooves on the surfaces of the cooling fins, the heat transfer areas are increased and the heat transfer boundary layers are continuously fractured, thus improving the heat transfer effect and increasing the secondary heat transfer areas of the cooling fins.
Description
Technical field
The invention belongs to technical field of heat exchangers, particularly a kind of plate-fin heat exchanger fin.
Background technology
Aluminum plate-fin heat exchanger is made up of the ripple type fin, is welded through dividing plate between the adjacent fin, and the top 1 of fin all contacts with dividing plate with root 2; And top 1 is wedge angle with root 2, and as shown in Figure 1, bonding area is less when soldering; Structure is insecure, and in addition, fin is used for dispelling the heat; And this fin surface 3 is a slab construction, makes that its heat-transfer effect is relatively poor.
Summary of the invention
Insecure in order to solve the welding of existing heat exchanger fin and dividing plate, the problem of fin heat-transfer effect difference.The invention provides a kind of heat-transfer effect heat exchanger fin preferably.
Technical scheme of the present invention is achieved in that a kind of heat exchanger fin, and said fin is the ripple type fin, and the top of said ripple type fin and root are arc sections, and the surface of said ripple type fin is provided with groove and projection.
Preferably, the radian of said arc sections is the 90-180 degree.
Preferably, said fin is an aluminium material.
Preferably, the position of said groove and projection is corresponding.
Preferably, the keyway type that is shaped as, the circle or square of said groove and projection.
The invention has the beneficial effects as follows: the wedge angle with fin top and root in the heat exchanger among the present invention changes the circular arc end into, makes the contact area of fin top and root and last lower clapboard increase, and when soldering, it is big that bonding area becomes like this, and structure is more firm; In addition, through projection and groove are set, increased heat transfer area, heat transfer boundary layer is constantly broken, improved heat-transfer effect, increased the secondary heat transfer area of fin in fin surface.
Description of drawings
Fig. 1 is the structural representation of a kind of heat exchanger fin in the prior art;
Fig. 2 is the structural representation of a kind of embodiment of heat exchanger fin of the present invention;
Among the figure: 1 fin top, 2 fin roots, 3 fin surface, 4 grooves, 5 arc sections.
The specific embodiment
Do further detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention:
A kind of heat exchanger fin, said fin are the ripple type fin, and said ripple type fin top 1 is an arc sections 5 with root, and the surface of said ripple type fin is provided with groove 4 and projection.
The radian of arc sections described in the present invention 5 is the 90-180 degree.
Fin described in the present invention is an aluminium material.
The position of groove described in the present invention 4 and projection is corresponding, and the groove of fin surface 34 is to obtain through Sheet Metal Forming Technology with projection, on the surface in groove 4; Another side has the projection protrusion naturally; Therefore, the position of groove 4 and projection is corresponding, and size is also consistent with shape.
The keyway type that is shaped as, the circle or square of groove described in the present invention 4 and projection.
Embodiment: as shown in Figure 2, a kind of heat exchanger fin, said fin are the ripple type fin of aluminium material; The top of said ripple type fin and root are arc sections 5, and the contact area that the employing of arc sections 5 has increased fin and last lower clapboard increases, like this when soldering; It is big that bonding area becomes, and structure is more firm, preferably; The radian of arc sections 5 is the 90-180 degree, and said ripple type fin surface 3 is provided with groove 4 and projection, and shape, the size scientific research of groove 4 and projection are provided with arbitrarily as required; Preferably, the keyway type that is shaped as, the circle or square of groove 4 and projection are through being provided with groove 4 and projection in fin surface 3; Heat transfer boundary layer is constantly broken, improved heat-transfer effect, increased the secondary heat transfer area of fin.
What should explain at last is: the above is merely explanation embodiment of the present invention; Be not limited to the present invention; For a person skilled in the art; All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
