Abstract

The utility model discloses an air cooling heat-dissipation sectional bar special for electrical equipment. The air cooling heat-dissipation sectional bar special for the electrical equipment comprises a heat-absorption bottom and heat-dissipation fins. The heat-dissipation fins are integrally molded on the heat-absorption bottom along the length direction. A plurality of protrusions are molded on end surfaces of the heat-dissipation fins which are molded on the heat-absorption bottom and extend along the length direction, width of the protrusions is larger than that of the heat-dissipation fins, and the heat-dissipation fins are molded on the protrusions. With the technical improvement, the added protrusions can not only improve connection strength between the heat-dissipation fins and the heat-absorption bottom greatly but also increase heat-dissipation areas of the heat-absorption bottom, and therefore heat-dissipation effect is improved.

Description

The heat sink section bar that a kind of electrical equipment is special-purpose air-cooled

Technical field:

The utility model relates to the special-purpose air-cooled heat sink section bar of a kind of electrical equipment.

Background technology:

The electrical equipment that some caloric values are bigger usually all need be equipped with special-purpose heat dissipation equipment, and existing heat dissipation equipment adopts air-cooled equipment mostly, in order to cooperate the work of radiator fan; Generally all can on the bigger electric elements surface of caloric value, spread heat sink section bar, this heat sink section bar is made up of heat absorption base and radiating fin, and radiating fin is one-body molded on the heat absorption susceptor surface; The heat on heat absorption base and the radiating fin is taken away in the effect that utilizes fan to dry, thereby plays the effect of heat radiation; The shortcoming that the heat sink section bar of this structure exists is: because radiating fin thickness is general just thinner, cause it relatively poor with the bonding strength between the heat absorption base, use and keep in repair when assembling daily; Cause distortion because of receiving the external force effect easily, in addition, the heat absorption base is all made plane; Cause area of dissipation less, radiating effect is not good.

Summary of the invention:

The purpose of the utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of special-purpose air-cooled heat sink section bar of electrical equipment that not only can improve radiating effect but also can improve radiating fin intensity is provided.

For realizing above-mentioned purpose; The technical scheme that the utility model provides is: the heat sink section bar that a kind of electrical equipment is special-purpose air-cooled, include heat absorption bottom and radiating fin, and radiating fin is one-body molded on the heat absorption bottom; And moulding along its length; On the end face that forms radiating fin on the heat absorption bottom, form a plurality of convexities of extending along its length, protruding width is wideer than radiating fin width, and radiating fin is molded on this convexity.

After above-mentioned technological improvement, the bossing of increase both can make the radiating fin and the bonding strength of heat absorption base be greatly improved, and can increase the area of dissipation of heat absorption base again, improved radiating effect.

Description of drawings:

Fig. 1 is the structure chart of the utility model heat sink section bar.

Embodiment:

Combine accompanying drawing to set forth the utility model in detail at present:

The heat sink section bar that the electrical equipment of present embodiment is special-purpose air-cooled; Include heat absorption bottom 1 and radiating fin 2; Radiating fin 2 is one-body molded on heat absorption bottom 1, and moulding along its length, on the end face that forms radiating fin 2 on the heat absorption bottom 1, forms a plurality of convexities 3 of extending along its length; Protruding 3 width is wideer than radiating fin 2 width, and radiating fin 2 is molded on this convexity 3.

The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection range of the utility model.

Claims

1. the special-purpose air-cooled heat sink section bar of an electrical equipment; Include heat absorption bottom and radiating fin; Radiating fin is one-body molded on the heat absorption bottom, and moulding along its length, it is characterized in that: on the end face that forms radiating fin on the heat absorption bottom, form a plurality of convexities of extending along its length; Protruding width is wideer than radiating fin width, and radiating fin is molded on this convexity.
