Abstract

The utility model relates to an assembled radiator, comprising a plurality of section plates which are provided with the base plates and the fins. The lower part of the cross section of the section plate is provided with a base plate. The base plate is provided with a fin which has the same direction with the base plate. The left and the right two side surfaces of the base plate are respectively provided with a dovetail and a dovetail slot. As the positioning and assembling theory of the dovetail slot is adopted, the radiators with various sizes and multiple forms are assembled, the problems of the device tonnage and the mould manufacturing of the assembly are avoided, large quantity of material is saved, and the manufacturing cost is reduced. The radiating direction has no interface problem. Under the same radiating area, the product weight of the combination power electron radiator is reduced by 30% to 50%.

Description

Combined radiator

Technical field:

The utility model relates to a kind of radiator, particularly relates to a kind of combined radiator.

Background technology:

At present, radiator in the prior art, for example the radiator of integrated circuit (IC) chip, large-scale inverter etc. can be divided into dull and stereotyped single rib type (referring to Fig. 3 and Fig. 4), square chest type (referring to Fig. 5), special-shaped (referring to Fig. 6, Fig. 7) and blade inserting (referring to Fig. 8); The single rib type of described flat board, square chest type and abnormal shape are the extrusion process mode and produce, the little gentle extrusion process technical conditions restriction of mold design that is squeezed of the version of its product and size, the essential redesign of each new section structure is made mould, by forming product after the die trial; Because the restriction of Mould design and manufacturing process, the tongue ratio of radiator can not be done very greatly, and along with the increase of section structure size, need the large-tonnage extruder to produce, thereby the price of die cost and section bar has also improved much thereupon.Described fin-inserted radiator, though be that certain improvement is arranged, squeeze out band slot substrate after because its substrate width is certain, can not be applicable to the needs of any width, and there is the interface in slot on heat dissipation direction, reduced radiating efficiency.

Summary of the invention:

The order composite type electric power electronic radiation device that the utility model relates to is to remedy the deficiencies in the prior art.

The utility model is realized as follows: a kind of combined radiator, it is to be combined by several profile plates that have substrate and fin, the bottom of described profile plate is provided with substrate, on substrate, be provided with and the equidirectional fin of substrate, on the face of the left and right sides of substrate, be respectively equipped with dovetail and dovetail groove.

Described several each self-corresponding dovetails of profile plate are inserted in the dovetail groove, after the lower inclined plane in the lower inclined plane of dovetail and the dovetail groove contacts, and the substrate bottom surface of several profile plates plane that coexists.

The upper surface of dovetail groove one side of described substrate is provided with the press-loading process groove.

Described fin surface is provided with ripple.

The described radiator both sides that constitute are respectively arranged with one-sided backplate with dovetail groove or dovetail.

When using, according to the length of required size by the size intercepting profile plate of some directions, and the number of press other direction intercepting profile plate, the plug-in mounting by dovetail on two adjacent profiles plates and dovetail groove makes up, compresses, and profile plate is combined into one; When needs square chest type radiator, install backplate additional by both sides, the top is provided with cover plate and just can realizes.

The utility model combined radiator good effect is: owing to adopt dovetail groove location compound mode, can be combined into the radiator of various sizes and various ways as required, not only avoided tongue than the equipment tonnage of higher assembly and the manufacturing issue of mould, a large amount of raw material have been saved, reduced cost of manufacture, and do not have interface problem on heat dissipation direction, under identical area of dissipation, the product weight of its composite type electric power electronic radiation device can reduce 30-50%.

Below in conjunction with accompanying drawing the utility model is described further.

Embodiment:

As Fig. 1, Fig. 2, shown in Figure 9, the combined radiator that the utility model relates to, it is to be combined by several profile plates that have substrate 1 and fin 4, the bottom of described profile plate is provided with substrate 1, on substrate 1, be provided with and substrate 1 equidirectional fin 4, on the face of the left and right sides of substrate 1, be respectively equipped with dovetail 5 and dovetail groove 2.

Described several each self-corresponding dovetails 5 of profile plate are inserted in the dovetail groove 2, after the lower inclined planes in the lower inclined plane of dovetail 5 and the dovetail groove 2 contact, and the plane that coexists, substrate 1 bottom surface of several profile plates.

The upper surface of dovetail groove 2 one sides of described substrate 1 is provided with press-loading process groove 3, profile plate after the combination, compress by the upper surface to dovetail groove 2 one sides of substrate 1, make it be fixed into one, the press-loading process groove 3 that is provided with has then solved because compress the problem of stress concentration that causes.

Described fin 4 surfaces are provided with ripple 8, are beneficial to improve the area of dissipation of spreader surface.

The described radiator both sides that constitute are respectively arranged with one-sided backplate with dovetail groove or dovetail, can affixed again cover plates on backplate, and to be combined into square chest type radiator.

A kind of embodiment of the present utility model, as shown in Figure 2, by the principle of combinations thereof, both sides have additional backplate 6, install the composite type electric power electronic radiation device that cover plate 7 is made into the square chest type additional.
