Abstract
The utility model relates to a modular section bar radiator, the radiating fin by two section bar radiators inserts each other and connects fixedly in the other side fin and form, has set up and has included: the high fins and the low fins are determined according to the positions of screws for mounting the power device and are used for mounting and fixing mounting pins of the radiator. The radiator has the advantages that the heat dissipation area is multiplied under the condition that the difficulty of a mould is not increased, the radiator is particularly suitable for various power electronic products with power devices arranged on two or three surfaces, the air duct length can be shortened, and the size of a case is reduced.
Description
Technical Field
The utility model relates to a section bar radiator for small-size power electronic power control equipment especially relates to an increase heat radiating area's combination formula section bar radiator.
Background
At present, the section radiator in industrial equipment is limited by die processing and extrusion processes, the fin spacing of the radiator cannot be sufficiently dense, and as is known, the extruded section radiator is the lowest in cost among the extruded section radiator, the water-cooled radiator, the inserted sheet radiator, the shovel sheet radiator and the heat pipe radiator. How to reduce the cost and reduce the volume of the power electronic product or how to increase the heat dissipation power of the section bar heat radiator under the condition of unchanged volume becomes the difficult problem of a plurality of structural designers.
Disclosure of Invention
To above needs and to prior art's weak point improve, the utility model aims to solve the technical problem that a small size, powerful section bar radiator is provided to realize short wind channel, low-cost purpose.
In order to solve the technical problem, the utility model relates to a modular section bar radiator comprises section bar radiator one and section bar radiator two, and in section bar radiator one and section bar radiator two's radiating fin inserted the other side fin each other, the boss of section bar radiator two inserted the concave station and the screw connection of section bar radiator one fixed, and mutual ground connection is more reliable, can also utilize metal elastic deformation, and the mutual lock joint of pit that adopts section bar radiator two's plush copper to insert section bar radiator one is fixed. The radiating fins comprise high fins and low fins determined according to the positions of the screws for mounting the power devices, and the bottom of each screw is prevented from interfering with corresponding section radiator fins.
The utility model discloses an among the section bar radiator, there are plane one and plane two that are used for installing power device, still be provided with and be used for installing fixed installation foot.
The utility model discloses an optimal structure, two last planes three that have the power device that is used for installing of section bar radiator, the radiating fin of section bar radiator two is the same and the adaptation with low fin size with section bar radiator one high fin.
As a further improvement, the mounting feet provided on the second section bar radiator are the same as and symmetrical to the mounting feet on the first section bar radiator.
The section bar radiator is particularly suitable for various power electronic products with two or three surfaces provided with power devices, the radiating area is doubled under the condition of not increasing the difficulty of a mould, the length of an air channel can be shortened, and the volume of a case is reduced.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Detailed Description
Fig. 1 shows the utility model discloses an application of first embodiment combination formula section bar radiator on IGBT single tube converter, and the fixed position of screw connection is only represented with the central line, and power device's mounting screw passes the radiator base plate as shown two dot chain lines in the figure, and two 2 shortening fins of the section bar radiator that correspond make mutual noninterference, and the position decision of mounting screw corresponds the radiator fin and lets the position.
In fig. 2 and 3, the first profile heat sink 1 is provided with a first plane 11 and a second plane 12 for mounting power devices, the second profile heat sink 2 is provided with a third plane 22 for mounting power devices, and a high fin 15 and a low fin 14 for dissipating heat, and the low fin 14 is not limited to the position shown in the figure and can be in any required position. The first section radiator 1 is provided with a concave platform 13 for the second section radiator 2 to insert the boss 21 and screw to connect, and is also provided with a mounting foot 16 for fixing the first section radiator 1. Because of the combination characteristic that the radiating fins of the first sectional material radiator 1 and the second sectional material radiator 2 are mutually inserted, the high fins 15, the low fins 14 and the mounting feet 16 of the first sectional material radiator 1 are also embodied in the second sectional material radiator 2 in an axisymmetric shape.
Fig. 4 shows a combined type profile heat sink according to a second embodiment of the present invention, wherein the raised head 41 of the second profile heat sink 2 is inserted into the recess 31 of the first profile heat sink 1 to be fastened and fixed by metal elastic deformation.
