Detailed Description
As shown in fig. 1-3, the heat sink of the present embodiment includes a heat sink body, and further includes a connection plate 2. The radiator body is formed by inserting a pair of profile radiators 1 in a staggered mode in the same direction, fins 1-2 of one profile radiator 1 are inserted into gaps of adjacent fins 1-2 of the other profile radiator 1, and after insertion, the end faces of the fins 1-2 of the profile radiators are in contact with the base plate 1-1 of the opposite profile radiator. In order to ensure the appearance after insertion, the relative sizes of the substrate 1-1 and the fins 1-2 of the profile heat sink 1 are designed, as shown in fig. 5, in the preferred embodiment, the edge width of one end of the substrate 1-1 of the profile heat sink 1 is greater than the edge width of the other end, the difference between the edge widths is 1/2 of the distance between the adjacent fins 1-2, the excess edge width is used for placing the fins 1-2 of the other profile heat sink 1, and a pair of profile heat sinks 1 are inserted to form a structure in which the end faces of the two substrates 1-1 are on the same horizontal plane. In order to increase the heat dissipation area and improve the heat dissipation efficiency, as shown in fig. 6, the side surface of the fin 1-2 of the preferred profile heat sink 1 of this embodiment is a corrugated curved surface. The connecting plate 2 is a thickened aluminum plate, the connecting plate 2 is arranged between the base plates 1-1 of the pair of profile radiators 1, as shown in figure 1, the connecting plate 2 is arranged on the outer side of the base plates 1-1, the surface of the connecting plate 2 is in contact with the end faces of the base plates 1-1, the height of the connecting plate 2 is the distance between the pair of base plates 1-1, the width of the connecting plate 3 corresponds to the width of the base plates 1-1, the connecting plate 2 is parallel to the fins 1-2, and the pair of connecting plates 2 and the base plates 1-1 of the pair of profile radiators 1 are combined end to end. The connecting plate 2 can also be connected with the surface of the base plate 1-1 on which the fins 1-2 are arranged, and the end surfaces of the connecting plate 2 and the base plate 1-1 are the same surface. The connecting plate 2 and the base plate 1-1 can be fixed in various ways, and the preferred connecting plate 2 and the base plate 1-1 of the profile radiator 1 are welded through friction; the connecting plate 2 is fixedly connected with a base plate 1-1 of the profile radiator 1 through threads. A group of threaded holes 3 are formed in the connecting plate 2 and the base plate 1-1, so that the heating element can be conveniently fixed with the radiator in the embodiment.
In actual production and processing, as shown in fig. 4, a pair of profile radiators 1 are placed in a specified form, the narrow side of one profile radiator 1 faces upwards, the narrow side of the other profile radiator 1 faces downwards, and after the fins 1-2 of the profile radiators 1 are inserted into each other, a pair of connecting plates 2 are fixed with the base plates 1-1 of the profile radiators at two ends respectively, so as to complete the assembly of the radiators. Because the section bar radiators 1 with the same specification are assembled, the double-substrate radiator can be produced and processed without additional die sinking, the production cost is saved, and the flexibility of the product is improved. .
