Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation of power distribution equipment, and in particular relates to a heat dissipation structure which is dust-proof and moisture-proof. Background Art

[0002] When the power distribution equipment is working continuously, it will inevitably generate a lot of heat. Since the power distribution equipment is relatively closed, the internal temperature will rise, and the service life of the internal components will be shortened due to poor heat dissipation. The heat dissipation device is necessary for the power distribution equipment, and the purpose of heat dissipation inside the equipment is achieved by forming air convection through the heat dissipation holes.

[0003] In the prior art, commonly used heat dissipation holes are straight-through type and intermediate filling type. The straight-through type has a large ventilation volume, but dust and moisture can easily enter the interior of the equipment and affect it; while intermediate filling cotton yarn and small-aperture filling can easily clog the channel, completely losing the ventilation and heat dissipation function. Utility Model Content

[0004] In order to solve the above problems, the technical solution adopted by the utility model is:

[0005] A heat dissipation structure that is dust and moisture proof, comprising:

[0006] A frame is provided on which a heat dissipation component is fixed.

[0007] Furthermore, the heat dissipation assembly includes a grille and a partition with convex holes, the partition is located on the inner side of the grille, and the grille is fixed to the inner edges of both sides of the frame.

[0008] Furthermore, the grilles are provided in a plurality and are evenly distributed.

[0009] Furthermore, the grilles are arranged to be inclined toward the inside of the frame, and the grilles on both sides are inclined in opposite directions and are symmetrically distributed.

[0010] Furthermore, two partitions are provided and fixed inside the frame and located between the grilles on both sides.

[0011] Furthermore, a plurality of convex holes are provided on the partition plate and are evenly distributed, and the convex holes protrude toward one side of the inner portion of the frame.

[0012] Furthermore, the convex holes on the two partitions are staggered and are in a contracted shape.

[0013] Furthermore, the large end of the contracted convex hole is arranged close to the partition.

[0014] Beneficial effects of the utility model:

[0015] The utility model provides a heat dissipation structure that prevents dust and moisture from entering. The inclined partition will perform the first filtering and deceleration. The staggered setting of the convex holes will form a tortuous channel, and the flow rate will slow down, so that dust particles and moisture cannot enter the cabinet. Since there is no need to fill the interior with small-aperture fillers and the convex holes are large round holes, the air intake is guaranteed and the channel is not easily blocked.

[0019] The utility model provides a heat dissipation structure that is dust and moisture proof. The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings to make it easier to understand and grasp.

[0020] Example 1

[0021] refer to Figure 1-2 , a heat dissipation structure that prevents dust and moisture from entering, comprising:

[0022] A frame 1 is provided with a heat dissipation component fixed on the frame 1.

[0023] In this embodiment, the heat dissipation assembly includes a grille 2 and a partition 3 with convex holes 4 . The partition 3 is located on the inner side of the grille 2 . The grille 2 is fixed to the inner edges of both sides of the frame 1 .

[0024] In this embodiment, a plurality of grilles 2 are provided and evenly distributed so as to achieve the purpose of filtering and slowing down the air for the first time.

[0025] In this embodiment, the grille 2 is tilted toward the inside of the frame 1, and the grilles 2 on both sides are tilted in opposite directions and symmetrically distributed. The tilted grille 2 prevents air from blowing directly toward the convex holes 4 on the partition 3, thereby filtering strong winds.

[0026] In this embodiment, two partitions 3 are provided and fixed inside the frame 1 , and are located between the grilles 2 on both sides, so that air can enter the partitions 3 after passing through the grilles 2 .

[0027] In this embodiment, a plurality of convex holes 4 are provided on the partition 3 and are evenly distributed. The convex holes 4 protrude toward the inner side of the frame 1. At this time, the air flow rate slows down, and dust particles sink due to their own weight, while the humid gas condenses into water droplets. The convex setting prevents them from passing through the partition 3, thereby achieving the purpose of moisture-proofing.

[0028] In this embodiment, the convex holes 4 on the two partitions 3 are staggered and contracted, so that the air flow path between the partitions 3 forms a tortuous channel, thereby performing a second deceleration on the wind speed.

[0029] Preferably, the convex hole is in the shape of a large trumpet-shaped circular hole, which ensures the air intake and the passage is not easily blocked.

[0030] In this embodiment, the large end of the contraction-shaped convex hole 4 is arranged close to the partition plate 3 to facilitate the guidance of air circulation.

[0031] When the utility model is in use, the grille 2 inclined on one side prevents the air from blowing directly onto the convex holes 4 on the partition plate 3 behind it, thereby achieving the purpose of filtering and slowing down the strong wind; the convex holes 4 on the two partition plates 3 are made into a trumpet shape and are relatively staggered, so that the air circulation route between the partition plates 3 forms a tortuous channel, and the wind speed is slowed down for a second time; the convex holes 4 bulge inwardly, and when the air flow speed slows down, the dust particles sink due to their own weight, and when the humid gas reaches the wall of the last layer of partition plates 3, it will condense into water droplets, and the raised edges of the convex holes 4 also prevent it from passing through the partition plates 3, thereby achieving the purpose of moisture-proofing; when the air flow passes through the last layer of inclined grille 2, the air flow will be slowed down again, so that a small amount of escaping dust and moisture cannot reach the surface of the equipment to cause damage; at the same time, since there is no need to fill the interior with small-aperture fillers, it is guaranteed that the air intake will not be reduced.

[0032] The above fully describes the technical solution of the present invention. It should be noted that the specific implementation of the present invention is not limited to the above description. All technical solutions formed by ordinary technicians in the field using equivalent or equivalent transformations in structure, method or function based on the spirit of the present invention fall within the protection scope of the present invention.
