[Technical field to which the invention belongs]

 The present invention relates to a radiator scale structure in which a plurality of heat-dissipating pieces are divided into a plurality of pieces, and the heat-dissipating pieces are bent upward and arranged.

[0002]

[Prior art]

 In order to solve the problem of overheating inside the computer, heat dissipating pieces are generally added on electronic heating parts such as CPU, IC, liquid crystal chip and power supply, and the high temperature generated by the electronic parts is dissipated by the heat dissipating pieces.

As shown in FIG. 1, a heat dissipating piece 1 and a bottom plate 2 are integrally formed by aluminum die processing, and there is a limit in a technique of pressing against a model or applying pressure. It was wide, thick, had a large area that impeded airflow, and the heat transfer rate was relatively slow. The number of heat dissipating pieces was small, the heat dissipating area was also small, and the heat dissipating effect was limited.

[0004] FIG. 2 shows the one developed there. The heat-dissipating pieces are installed as a large number of heat-dissipating columns 4 on the main body 3, and the high temperature generated when the electronic components operate is conducted and released by the heat-dissipating columns. This kind of heat dissipating piece has a larger heat dissipating area and heat dissipating space than before, and the heat dissipating effect is relatively good.

[0005]

[Problems to be solved by the invention]

 However, at the time of manufacturing, it is necessary to first form the heat-dissipating columns 4 in a long lump, and since the heat-dissipating columns 4 are evenly spaced, processing costs, time and production materials are wasted. The heat dissipation effect was not ideal because the heat transfer rate of electronic heat-generating components, which are required to be used quickly or for a long period of time, was large because of relatively large thickness.

According to the present invention, a plurality of heat dissipating scales are formed by bending the divided heat dissipating pieces, and the heat dissipating surface area is greatly increased. In addition, since the heat-dissipating pieces are multiple heat-dissipating scales formed directly by bending, there is no material to be discarded at all, which saves materials, reduces work time, and reduces costs.

[0007]

[Means for Solving the Problems]

 The heat-dissipating pieces are divided into a plurality of pieces, and both sides are pushed upward and bent, facing two-to-two, and heat-dissipating scales arranged in a U-shape. The heat-dissipating scales are pushed upward from the bottom. The bent position is different, the outer scale and the inner scale are not parallel, and the outer scale and the inner scale are arranged and arranged at an interval, forming a heat conducting plate in the center of the bottom that is not bent.

[0008]

[Embodiment]

 As shown in Figs. 3 and 4, the heat dissipating piece is a thin rectangular piece divided into a plurality of pieces, each of which is bent upwards on both sides, and arranged in a two-to-two relationship to form a U-shaped heat dissipating scale group. 10 are formed. The number of the heat dissipating pieces is several times as large as that of the prior art, and the unbent portion at the bottom middle portion alternately forms a wide and narrow heat conducting plate 13.

The heat-dissipating scales group 10 is bent upward from the bottom and arranged in and out so as not to be parallel to different positions. , And the distance between the inner scales is relatively short, forming an inner scale 12. The outer scale 11 and the inner scale 12 are arranged in a row at intervals, and triangular airflow sections 14 are formed on both sides of the heat dissipating scale 10.

As shown in FIG. 5, when pressure is applied, the sheet is cut along a predetermined cutting line 101 and simultaneously bent upward along a folding line 102, thereby wasting production material. Without applying pressure once, the heat dissipating scale group 10 as shown in FIG. 3 can be completed, no processing is required, time can be saved, and materials and costs can be reduced.

As shown in FIG. 6, when combined, the heat dissipating scale group 10 is installed on the heat absorbing bottom plate 20 with a heat conductive adhesive and fixed using the installation holes 15 provided on the heat conductive plate 13 in advance. And the combination is simple. By applying pressure to the scales of the heat dissipating scale group 10 and forming them into a thin rectangular shape with a high height, the heat conduction speed can be relatively high, and the number of scales can be doubled. The area will be greatly increased and the exhaust heat capacity will be increased.

Further, the outer scale 11 and the inner scale 12 are designed to be arranged at an interval, and a triangular airflow section 14 is formed between the outer scale 11 and the inner scale 12 so that when the airflow flows, the inner and outer scales are formed. Convection occurs due to the difference between the arrangement angle and the airflow. The surface of each scale can uniformly contact the airflow, the airflow velocity can be increased by matching the gap formed between the heat-dissipating scales, and the overall heat-dissipating effect is enhanced. The heat absorbing bottom plate 20 continuously transmits the heat of the heat guide plate 13 and quickly dissipates the heat.

[0013]

[Effect of the invention]

 Since the heat-dissipating pieces are thin and rectangular, the number of scales can be doubled, and the total heat-dissipating area of the heat-dissipating pieces can be greatly increased. .
