Abstract

The creation of the present invention is mainly related to a kind of heat sink, which is mainly formed by the frame opening formed by the arrangement of two plates and two second inclined plates, so that the creation can be sleeved on the top of the casing to have the effect of easy installation. After installation, the air flow path formed by the inner space of the cover can be passed through, so that the heat generated by the shell can be taken away to achieve the effect of cooling. At the same time, two first inclination and bottom walls with multiple holes are combined to allow rainwater falling into the cover to be discharged.

Description

heat sink

The creation of the present invention relates to a radiator installed on the top of the casing.

Press, the electric box includes distribution box, substation box, etc. Please refer to Taiwan Patent Certificate No. M577201 "High-voltage distribution box structure improvement", the patent system discloses: a distribution box body, the front of the distribution box body is provided with an opening, and A side cover pivotally connected to one side of the opening, the side cover is used to close or open the opening of the distribution box body; and a movable sliding door, which is movably arranged in the opening and blocks the opening from the inside of the distribution box body In addition, there are many partitions in the installation space inside the distribution box body, and each partition is blocked between groups of electrical equipment. In this way, the structure of the high-voltage distribution box of this creation can be improved to achieve the safe separation of electrical equipment inside the high-voltage distribution box, and an extra safety protection between the opening of the electric box and the internal high-voltage switch.

Although this patent has the aforementioned advantages, however, due to the long-term exposure of some electric boxes (such as transformer boxes) to outdoor sunlight, the overall temperature tends to remain high, which not only affects internal components to a considerable extent, but also affects public Safety is also a hidden concern. In addition, not only electric boxes have heat dissipation problems, but other items with shells and mechanical or electrical appliances also have similar problems. For this reason, the creator of the present invention believes that there is a need for improvement, and started thinking about a solution.

In view of the shortcomings described in the prior art, the creator of the present invention provides a heat sink including: A cover body for covering the top of the housing and two first inclined plates. One of the adjacent side edges of the two first inclined plates is respectively connected to the inner side of the top wall of the cover, and each first inclined plate is separated from the one The side edge faces the opposite side edge and slopes downward to have a first distance from the front and rear inner side walls of the cover. The top wall of the cover is provided with two first air outlets, and each first air outlet is located at Above each first inclined plate; two second inclined plates are respectively arranged below each first inclined plate, and the inclination direction of each second inclined plate is the same as the first inclined plate above, and the other end of each second inclined plate is connected to The front and back two inner side walls of the cover have a second interval, and a bottom wall with a plurality of first holes is respectively arranged along each second interval.

This creation allows the creation to be easily installed on the top of the shell through the inner edge of each board body and the frame openings jointly framed by each second inclined board. When rainwater falls into the cover from each first air outlet When in the body, rainwater can be guided to the bottom wall to be discharged through the guidance of each first inclined plate and each second inclined plate, so as to prevent rainwater from accumulating inside the cover.

In addition, the opposite side edge of each first inclined plate (3) is respectively provided with a stopper plate (31) upward, and each first inclined plate (3) is provided with a plurality of drop holes (32) adjacent to the other side edge. ), in this way, when there is too much rain, the stop baffle (31) can exert a stopping effect to prevent the cover (1) from being unable to drain the internal rain water in time.

Two second inclined plate (4):

Please refer to the first to third figures, the two second inclined plates (4) are respectively arranged under each first inclined plate (3), so that the second inclined plate (4) and the first inclined plate (3) There is a flow hole (41) between ), and the flow hole (41) communicates with the first air outlet (11) to form a flow path for air circulation. The inclination direction of each second inclined plate (4) is the same as that of the first inclined plate (3) above, and the other end of each second inclined plate (4) has a line with the front and rear inner side walls of the cover (1). In the second interval, a first bottom wall (5) with a plurality of first holes (51) arranged along each second interval is respectively provided, so as to discharge the rainwater inside the cover body (1).

Please refer to the fourth figure and the fifth figure again, wherein the number of the first air outlets (11) is preferably four, and they are respectively arranged on the four edges of the top surface of the cover body (1), and are as As mentioned above, the first inclined plate (3) and the second inclined plate (4) are respectively provided below each first air outlet (11), such as the fifth As shown in the figure, each second inclined plate (4) has a second distance from the front and rear inner side walls of the cover body (1), and each second inclined plate (4) is connected to the left and right inner side walls of the cover body (1).
