Abstract

The utility model discloses a casting mould for a copper radiating tube. The mould comprises a base, an outer wall and a solid column arranged inside the outer wall, wherein an annular gap is formed between the outer wall and the solid column, the inner surface of the outer wall is provided with a plurality of flaky bulges, the solid column is located above the base, and the base, the outer wall and the solid column form an integral structure. According to the casting mould, the inner surface of the outer wall is provided with the plurality of flaky bulges at equal intervals, so that radiating fins which form an integral structure with the copper tube can be formed at the outer part of the copper tube formed by casting, and the fins are firmly combined with the copper tube; the radiating fins and the flaky bulges are meshed with each other, so that the equal interval among the radiating fins is realized, the radiating fins are uniformly distributed at the outer surface of the copper tube, the heat dissipation performance is good, and the structure is stabler.

Description

A kind of copper radiating tube casting mold

[technical field]

The utility model relates to the technical field of casting mold, particularly the technical field of copper radiating tube casting mold.

[background technology]

Because copper has good heat conductivility, therefore copper pipe is widely used in various electronics and digital product as heat sink material, but traditional copper radiating tube is in order to improve heat dispersion, often by sheathed aluminum radiating fin or copper radiating fin on copper pipe, but because sheathed radiating fin is fixing unstable, the easy landing of radiating fin of end, the radiating fin that is positioned at center may too closely cause heat dispersion to decline, and heat dispersion is unstable.

[utility model content]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of copper radiating tube casting mold, can produce the copper radiating tube that a kind of fin and copper pipe are integrated, and has improved heat dispersion and the radiation stability of copper radiating tube.

For achieving the above object, the utility model proposes a kind of copper radiating tube casting mold, comprise base, outer wall, solid post, described outer pars intramuralis is provided with solid post, between outer wall and solid post, form an annular space, the inner surface of outer wall is provided with some lamellar projections, and described solid post is positioned at the top of base, and base, outer wall and solid post form integrative-structure.

As preferably, the width of described lamellar projection is less than the thickness of annular space, and the height of lamellar projection equals the height of solid post.

As preferably, described lamellar projection circular array is distributed on the inner surface of outer wall, gap between every two lamellar projections equates, the structure of lamellar projection makes the copper pipe outside of moulding by casting can form the radiating fin into a single integrated structure with copper pipe, and the spacing between radiating fin equates, be uniformly distributed, heat dispersion is good, and structure is more stable.

As preferably, the upper surface of described annular space is connected with outside, and the lower surface of annular space and the upper surface of base form enclosed construction.

The beneficial effects of the utility model: the utility model is by the some lamellar projections of inner surface spaced set at outer wall, make the copper pipe outside of moulding by casting can form the radiating fin into a single integrated structure with copper pipe, fin firmly combines with copper pipe, because radiating fin and lamellar projection intermesh, therefore the spacing between radiating fin equates, be uniformly distributed the outer surface with copper pipe, heat dispersion is good, and structure is more stable.

Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.

[accompanying drawing explanation]

Fig. 1 is the main pseudosection of a kind of copper radiating tube of the utility model casting mold;

Fig. 2 is the top plan view of a kind of copper radiating tube of the utility model casting mold.

In figure: 1-base, 2-outer wall, 3-solid post, 4-annular space, 5-lamellar projection.

[specific embodiment]

Consult Fig. 1 and Fig. 2, a kind of copper radiating tube of the utility model casting mold, comprise base 1, outer wall 2, solid post 3, described outer wall 2 inside are provided with solid post 3, between outer wall 1 and solid post 2, form an annular space 4, the inner surface of outer wall 2 is provided with some lamellar projections 5, described solid post 3 is positioned at the top of base 1, base 1, outer wall 2 and solid post 3 form integrative-structure, the width of described lamellar projection 5 is less than the thickness of annular space 4, the height of lamellar projection 5 equals the height of solid post 3, described lamellar projection 5 circular array are distributed on the inner surface of outer wall 2, gap between every two lamellar projections 5 equates, the upper surface of described annular space 4 is connected with outside, the upper surface of the lower surface of annular space 4 and base 1 forms enclosed construction.

The utility model course of work:

A kind of copper radiating tube of the utility model casting mold in the course of the work, the copper water of fusing is poured in annular space 4 and poured into a mould, by the some lamellar projections 5 of the inner surface spaced set at outer wall 2, make the copper pipe outside of moulding by casting can form the radiating fin into a single integrated structure with copper pipe, fin firmly combines with copper pipe, because radiating fin and lamellar projection 5 intermesh, therefore the spacing between radiating fin equates, be uniformly distributed the outer surface with copper pipe, heat dispersion is good, and structure is more stable.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
