Abstract
The utility model relates to a cooling fin which comprises a cooling fin body. The cooling fin body is provided with a vapor channel and screw holes used for superimposing a polarity of cooling fins. The screw holes are arranged on the vapor channel which is provided with an opening at on end and the opening end is sealed by an end cover. Since the vapor channel is provided with one opening at one end, the utility model can adopt a loose core molding and has the advantages of simple technique and stable quality.
Description
(1) technical field
The utility model relates to a kind of fin.
(2) background technology
Fin is basic parts of forming radiator, and it comprises a heat radiation lamellar body, and the heat radiation lamellar body has horizontal steam channel, also is provided with the screwed hole of the multi-disc fin that is used to superpose on the heat radiation lamellar body, and described screwed hole is positioned on the described steam channel.Its steam channel of existing fin is a cavity, and this structure adopts husky this chamber of core die cast owing to adopt husky core extrusion process, therefore produce technology complicated, easily produce the deficiency of substandard products.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing fin, the utility model provides a kind of fin, can adopt the mould molding of loosing core based on its structure, and moulding process is simple, steady quality.
The technical scheme in the invention for solving the technical problem is: a kind of fin, comprise the heat radiation lamellar body, described heat radiation lamellar body has steam channel, also be provided with the screwed hole of the multi-disc fin that is used to superpose on this heat radiation lamellar body, described screwed hole is positioned on the described steam channel, described steam channel one end opening, the openend of described steam channel is by an end cap seal.
Further, the cross section ovalize of described steam channel.
Further, described end cap is welded on the end face of openend of described steam channel.
Further, described screwed hole has two, is positioned at the two ends of described steam channel.
The utility model adopts the mould molding of loosing core when moulding, promptly form steam channel after loosing core, again by the openend sealing of end cap with steam channel.
The beneficial effects of the utility model are: 1. because an end opening structure of steam channel, so the utility model can adopt the mould molding of loosing core, and moulding process is simple, steady quality.2. the cross section ovalize of steam channel, the steam channel of this kind shape and the steam channel of other shapes by comparison, withstand voltage properties is more outstanding.
(4) description of drawings
Fig. 1 is a sectional side elevation of the present utility model.
Fig. 2 is cross-sectional figure of the present utility model.
Fig. 3 is the structural representation of end cap.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of fin, comprise heat radiation lamellar body 1, described heat radiation lamellar body 1 has the steam channel 2 of cross section ovalize, described steam channel 2 one end openings, the openend of described steam channel 2 is by an end cap 3 sealing, and this end cap 3 is welded on the end face of openend of described steam channel 2.Also be provided with the screwed hole 4 of two multi-disc fin that are used to superpose on this heat radiation lamellar body 1, described screwed hole 4 is positioned at the two ends of described steam channel 2.
By screwed hole 4 several cooling fins is assembled the composition radiator during use, water flowing steam in steam channel 2 is dispersed into heat indoor by fin.
Because an end opening structure of steam channel 2, so the utility model can adopt the mould molding of loosing core, and moulding process is simple, steady quality.
Certainly the cross section of steam channel 2 might not ovalize, also can be other shapes, but the steam channel of the steam channel of cross section ovalize and other shapes by comparison, and withstand voltage properties is more outstanding.
Claims (4)
1. fin, comprise the heat radiation lamellar body, described heat radiation lamellar body has steam channel, also be provided with the screwed hole of the multi-disc fin that is used to superpose on this heat radiation lamellar body, described screwed hole is positioned on the described steam channel, it is characterized in that: described steam channel one end opening, the openend of described steam channel is by an end cap seal.
2. fin as claimed in claim 1 is characterized in that: the cross section ovalize of described steam channel.
3. fin as claimed in claim 1 or 2 is characterized in that: described end cap is welded on the end face of openend of described steam channel.
