Description

  The present invention relates to a heat radiating unit and its manufacture, and in particular, a heat radiating unit that manufactures a plurality of heat radiating fins firmly on a base, thereby reducing production costs and improving the problem of base deformation. Related to.

  Today, electronic components within electronic devices (eg, central processing units) generate a large amount of thermal energy during operation, raising the temperature of the electronic components. If proper heat dissipation is not performed, the electronic component is placed in a heat state, the operation is unstable, and the electronic device is stopped or frozen. In addition, since the amount of heat generated increases as the speed of various electronic components increases, the importance of heat radiators applied to various electronic devices is increasing day by day.

Known radiators are generally divided into two types as shown in FIGS. 1 to 3, for example, one of which is an integrated radiator and the other is a single radiator fin superposed on each other. It is. One side of these radiating fins is folded and a coupling portion is installed, and welding is performed using the bent portion, and the radiating fin is coupled to a base to form a radiator.
However, since this type of radiator has to be welded, the machining process is complicated and is not suitable for current environmental protection. For this reason, in a certain trader, the heat dissipating fins are assembled on the base by a fitting method to form a fitting type radiator. Among these, the fitting type radiator 1 includes a base 10 and a plurality of heat radiation fins 11.

  The base 10 includes a plurality of concave tanks 101. The concave tank 101 is formed on one side of the base 10 and used to insert and install the radiation fins 11. Moreover, when fixing the above-mentioned radiation fin 11 on the base 10 with the current technology, there are approximately two types of fixing methods. The above-described radiating fins 11 are directly welded and fixed on the base 10 by a welding method (see FIG. 1 as an example).

  However, this type of method tends to increase manufacturing costs. As another method, first, the coupling portion 111 of the radiating fin 11 is loosely fitted into the concave tank 101 of the base 10 (see FIG. 2 as an example), and then the base 10 concave tank with the jig 12. It changes to the system which pushes out both sides of 101 and tightens according to it, and fastens the coupling | bond part 111 of this radiation fin 11 (refer FIG. 3 as an example). However, since the shape of the opening of the concave tub 101 in the radiating fin 11 only changes to the coupling portion 111 of the radiating fin 11, the fitting of the radiating fin 11 coupling portion 111 in the concave tub 101 remains loose. Separation problems due to thermal resistance and looseness are likely to occur.
