Abstract
The present invention discloses a heat radiating flange of a counter flow type heat exchanger; the body of the heat radiating flange is a sheet structure and is provided with a plurality of regularly distributed mushroom-shaped bosses. The present invention still discloses the producing method of a heat exchanger formed by the heat radiating flanges of the counter flow type heat exchanger; in the producing process, a plurality of heat radiating flanges are laminated to form a heat radiating flange group; two adjacent heat radiating flanges extrude and contact with each other so as to make the heat radiating flange bodies keep a certain distance. As the sheet heat radiating flanges are provided with regularly distributed bosses, when producing the heat exchanger, the adjacent heat radiating flanges are provided with a certain distance because of the mutual contact of the bosses so as to make the structure of the heat radiating flanges in the heat exchanger more compact, and to effectively prevent the adjacent heat radiating flanges from jointing together, improving the heat radiating capability of the heat exchanger.
Description
Technical field
The present invention relates to a kind of fin of heat exchanger, especially a kind of fin of contraflow heat exchanger.The invention still further relates to a kind of manufacture method of contraflow heat exchanger.
Background technology
Now, along with the development of technology, increasing electric/electronic device has entered people's life, and its kind and function are also more and more abundanter.Some equipment is because power consumption is very high, so can emit a large amount of heat in work.Most electronic component all is very sensitive for variation of temperature, if untimely being transferred away of these heats, can the direct operate as normal that influences equipment, in the time of serious even can burning apparatus and then cause fire.So, for the equipment of this high-power high heat, generally all can be provided with heat abstractor specially, so that its normally work of safety.
Existing heat abstractor generally is on the rack of equipment heat exchanger to be installed, and contraflow heat exchanger is wherein more common a kind of.Existing contraflow heat exchanger generally all adopts the fin of " several " font, as shown in Figure 1, though this structure can be accelerated scattering and disappearing of heat to a certain extent, but when mounted, this heat radiating fin structure can not be too compact, that is to say needs the distance that keeps enough between the adjacent fin, otherwise adjacent fin might be in contact with one another together, and directly influences radiating effect.The radiator that has is provided with convex 2 in order to solve the problem that adjacent fin is in contact with one another between adjacent fin 1, as shown in Figures 2 and 3, but can make heat converter structure too complicated like this, installs cumbersome.
Summary of the invention
Technical problem to be solved by this invention provides a kind of fin of contraflow heat exchanger, and the manufacture method that adopts the heat exchanger of above-mentioned fin formation, makes heat converter structure simple, and is easy for installation, and has better radiating effect.
For solving the problems of the technologies described above, the technical scheme of the fin of contraflow heat exchanger of the present invention is, the body of described fin is a sheet structure, and described heat sink body is provided with regularly arranged a plurality of mushroom projections.
The technical scheme of the manufacture method of heat exchanger of the present invention is to comprise the steps:
(1) aluminium foil sheet material is tested, described aluminium foil plate surface should not have serious sassafras hinders, scratches, and flawless must not have loose, crackle, be mingled with when observing under the low power metallomicroscope;
(2) aluminium foil sheet material is made fin with die stamping;
(3) at the edge of described fin gluing;
(4) the multilayer fin is carried out superimposed composition groups of fins, the projection of adjacent two fin is in contact with one another, and makes to maintain a certain distance between the heat sink body;
(5) joint of fin is stamped fluid sealant.
The present invention is by being provided with regularly arranged projection on the sheet fin, make and maintain a certain distance between the adjacent fin owing to projection is in contact with one another when making heat exchanger, make that the structure of fin is compact more in the heat exchanger, and can effectively avoid adjacent fin to fit together, improve the heat dispersion of heat exchanger.
Description of drawings
The present invention is further detailed explanation below in conjunction with drawings and Examples:
Fig. 1 is the profile of existing fin;
Fig. 2 is the vertical view that existing fin is installed convex;
Fig. 3 is the cutaway view that existing fin is installed convex;
Fig. 4 is the cutaway view of the fin of contraflow heat exchanger of the present invention;
Fig. 5 is the vertical view of the fin of contraflow heat exchanger of the present invention.
Reference numeral is among the figure, 1. fin; 2. convex; 3. mushroom projection; 4. ripple.
Embodiment
The structure of the fin of contraflow heat exchanger of the present invention is referring to Fig. 4 and shown in Figure 5, and the body 1 of described fin is a sheet structure, and described heat sink body is provided with regularly arranged a plurality of mushroom projections 3.The projection direction of described arbitrarily adjacent two projections is opposite, respectively to two lateral processes of described fin.Described heat sink body is provided with ripple 4.Described fin is made of aluminium foil.
The present invention also provides the manufacture method of the heat exchanger that a kind of fin of as above-mentioned contraflow heat exchanger constitutes, and comprises the steps:
(1) aluminium foil sheet material is tested, described aluminium foil plate surface should not have serious sassafras hinders, scratches, and flawless must not have loose, crackle, be mingled with, in order to avoid aluminium foil sheet material produces phenomenons such as cracking when observing under the low power metallomicroscope;
(2) aluminium foil sheet material is made fin with die stamping;
(3) at the edge of described fin gluing;
(4) the multilayer fin is carried out superimposed composition groups of fins, the projection of adjacent two fin is in contact with one another, and makes to maintain a certain distance between the heat sink body;
(5) joint of fin is stamped fluid sealant.
Among the present invention, owing to be provided with mushroom projection, and the projection direction of any vertical or horizontal adjacent two projections is opposite, make that projection and projection can be in contact with one another, as shown in Figure 4 when two fin were superimposed together, just have a fixing interval between two adjacent like this fin, and be unlikely to fit together mutually, to compare with the fin of existing " several " font, the present invention's structure after installing is compact more.Ripple on the described fin can effectively increase the area of dissipation of fin, thereby reaches better radiating effect.The aluminium foil heat-transfer rate is fast, adopts aluminium foil to make fin, can rapidly heat diffusion be opened, and makes that heat radiation is more timely.
