[Prior art]

 Conventionally, this type is as follows. What is disclosed in Utility Model Registration No. 296082 "Assembly Structure of CPU Seat and Heat Dissipation Mechanism" in Taiwan is a conventionally known small central processing unit. By providing a heat-dissipating fan at the top of the plate, the heat generated from the central processing unit is quickly diffused.

The following problems can be pointed out with respect to the conventional technology. The ones posted in the above-mentioned utility model apply only to the central processor with a relatively small area because the area of the heat sink is small.However, when a central processor with a large area is required, Since two or more heat sinks must be connected to the central processing unit, the cost is doubled and the assembly is very troublesome.

[0004]

[Problems to be solved by the invention]

 The present invention has been made in view of such problems of the prior art, and aims at providing the following things. The purpose of the present invention is to provide a radiator device which has a large area which can not only be applied to a central processing unit having a relatively large area but also dissipates heat to the central processing unit and reduces the cost thereof. Is to do.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a radiator device having a large area according to the present invention has the following structure. That is, the radiator device having a large area according to the present invention includes the radiator plate 1 and the substrate 2. Several radiating pieces 11 are erected on the radiating plate 1, and an exhaust passage 12 is formed between the radiating pieces 11. The heat sink 1 is provided with several coupling grooves 13. The substrate 2 is coupled above the heat radiating piece 11 of the heat radiating plate 1, and a hole 21 is provided in the substrate 2. Several rods 22 are provided from the periphery of the hole 21. The other end of the rod 22 supports the seat plate 23 in a concentrated manner, and the seat plate 23 is used for the electric fan 25 to pivot and rotate. Further, a side wall 26 extending downward is vertically provided on the substrate 2, and the side wall 26 is formed so as to approach the upper part of the heat radiation piece 11 of the heat radiation plate 1.

In this case, the radiator device having the increased area according to the present invention can be configured as follows. Since the rod 22 of the substrate 2 is formed to extend downward, the seat plate 23 is configured to sink below the substrate 2.

[0007]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings. In the exploded perspective view of the embodiment of the present invention shown in FIG. 1, the radiator device having an increased area according to the embodiment of the present invention is composed of main components such as a radiator plate 1 and a substrate 2. The radiator plate 1 is made of a metal material such as aluminum and is formed in a rectangular shape having a relatively large area bottom plane, so that the radiator 1 can be connected to the central processing unit from the bottom plane. Since the heat radiation piece 11 is provided upright on the heat radiation plate 1, the heat radiation plate 1 has a larger heat radiation area. An exhaust passage 12 is formed between the heat dissipating pieces 11 so that the gas flow path can be formed. The substrate 2 is coupled to the space above the heat dissipating piece 11 and fixed with fixing parts 14 such as screws as shown in the figure. can do. In order to connect with the central processing unit, the heat radiating plate 1 is provided with a connecting groove 13 so as to cross between the heat radiating pieces 11. Can be used for bonding.

The substrate 2 can be coupled to the heat sink 1 by various coupling methods, or a method using a fixing part 14 such as a screw as shown in the drawing is a general and appropriate method. A hole 21 is provided in the substrate 2, and the hole 21 is formed so as to be located above the lower heat radiation piece 11 of the heat radiation plate 1. Several rods 22 extending downward from the periphery of the hole 21 are provided, and the other end of the rod 22 can support the seat plate 23 in a concentrated manner. The seat plate 23 can be used to pivotally rotate the electric fan 25, or can be used to pivot the central axis of the electric fan 25 using a shaft tube 24 as shown. . Further, in order to obtain the best air blowing effect by the rotation of the electric fan 25, side walls 26 extending downward are provided on each side of the substrate 2. Since the side wall 26 is formed so as to approach the upper part of each side of the radiator plate 1, the gas blown by the rotation of the fan 25 is surely directed to both ends along the exhaust passage 12 of the radiator plate 1. By being discharged, the heat radiating plate 1 can obtain the best heat radiating effect.

In the combined state of the radiator device of the present invention shown in FIGS. 2 to 4, after the board 2 is connected to the heat radiating plate 1, the side walls 26 of the board 2 are already radiating pieces of four circumferences of the heat radiating plate 1. Since it is close to or joined to the upper part of 11, fan 25 is limited to rotate in the space surrounded by side wall 26. As described above, the gas generated by the fan 25 is blown along the exhaust passage 12 provided between the heat radiating pieces 11 and can be exhausted from both ends of the heat radiating plate 1. Is formed.

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained. In the radiator device having a large area according to the present invention, since the heat radiating plate has a large area, it can be directly connected to two or more small central processing units or large central processing units. Due to the design, the gas generated by the fan can be fully utilized, so that the hot air diffused from the heat radiation piece is effectively eliminated, and the best heat radiation effect can be exhibited.
