Description

Technical Field

[0001] The utility model relates to a charging pile, in particular to a heat dissipation mechanism and a charging pile. Background Art

[0002] Charging piles are also known as charging piles for new energy vehicles. Existing charging piles use heat exhaust fans to dissipate heat generated during operation. Since the entire device is located outside, dust from the outside will enter the interior through the heat dissipation holes on the charging pile where the heat exhaust fans are installed. To prevent dust from entering, filters are added to the heat dissipation holes to prevent dust from entering. Single-layer filters have a limited filtering effect, so multiple layers of filters are added, and the pores of each layer decrease. After long-term operation, the layer with smaller pores will be covered with dust, resulting in reduced heat dissipation efficiency. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a heat dissipation mechanism and a charging pile include a symmetrically arranged mounting back plate 1, wherein the mounting back plate 1 is provided with a filter element 2, a composite filter element 3 and a heat exhaust fan 4 on opposite sides of the mounting surface, wherein:

[0025] The composite filter element 3 is structurally divided into a plurality of equally spaced isosceles trapezoidal grooves 31 and a connecting portion 32 for connecting adjacent isosceles trapezoidal grooves 31. The lower bottom of the isosceles trapezoidal grooves 31 is open and is arranged toward the filter element 2.

[0026] Rectangular grooves 311 are respectively formed on the two waists of the isosceles trapezoidal groove 31 . Arc-shaped filter cloth members 33 are arranged in the rectangular grooves 311 . The outer side of the arc-shaped filter cloth member 33 is arranged in an arc shape toward the filter mesh member 2 .

[0027] Specifically, the mounting backplates 1 in the embodiment are fixed to the charging pile body by screws and are arranged symmetrically with respect to the ventilation holes on the pile body. After installation, the bottom gusset plate 5 is first fastened to the ports of the two mounting backplates 1 and then fixed with screws. The filter element 2, the composite filter element 3, and the heat exhaust fan 4 are then inserted in sequence. The top gusset plate 5 is then fastened to the ports of the two mounting backplates 1 and fixed with screws. After fastening, the top gusset plate 5 contacts the sides of the filter element 2 and the composite filter element 3.

[0028] The snap-fit ​​mentioned above is actually plug-in, which is a conventional connection structure design and will not be elaborated on.

[0029] It should be noted that the composite filter element 3 is a hard air-permeable felt board.

[0030] In the above technology, a composite filter element 3 with a composite shape is used as the filtering system with the smallest inner aperture, and an isosceles trapezoidal groove 31 and an arc-shaped filter cloth element 33 are combined to form a multi-faceted structure. After being combined with each other, there will be several angles. When the heat exhaust fan 4 is running, when the airflow passes through the composite filter element 3, it will also be blocked to a certain extent when passing through, thereby forming a vortex airflow at the angle, so that dust is accumulated at the angle as much as possible to ensure the permeability of the isosceles trapezoidal groove 31 and the arc-shaped filter cloth element 33. Compared with traditional and flat designs, it can greatly slow down the rate of decrease in heat dissipation efficiency.

[0031] Combine Figure 2 It can be seen that in the above embodiment, the distance between the heat exhaust fan 4 and the composite filter element 3 after assembly is 5-7 cm. The connecting portion 32 of the composite filter element 3 after assembly is in contact with the inner side of the filter element 2.

[0032] As an embodiment further provided by the present invention, a sponge column 6 is fixedly mounted on the arc-shaped filter cloth member 33 , and the sponge column 6 is distributed on the inner arc surface of the arc-shaped filter cloth member 33 .

[0033] Specifically, the airflow passing through the arc-shaped filter cloth member 33 will be blocked by the sponge column 6 and flow along the curved surface of the sponge column 6 , thereby adhering to the finer dust particles passing through the arc-shaped filter cloth member 33 .

[0034] As another embodiment further provided by the present invention, arc-shaped guide members 7 are fixedly mounted on the arc-shaped filter cloth member 33 and are arranged symmetrically about the center of its outer arc surface. One end of the two arc-shaped guide members 7 extends to the extension line of the arc top of the arc-shaped filter cloth member 33, and an air intake groove 71 is formed between the two.

[0035] Furthermore, the arc-shaped guide member 7 is composed of a plastic frame with a breathable non-woven fabric provided on the outside.

[0036] Specifically, when the heat exhaust fan 4 in the embodiment is running, when the airflow passes through the composite filter element 3, it will be blocked by the arc-shaped guide element 7, thereby forming a filtering system, and then the airflow passing through the arc-shaped guide element 7 will enter the interior through the arc-shaped filter cloth element 33.

[0037] The dust in the composite filter element 3 will be suspended on the arc-shaped guide element 7, and will be blocked and unable to be filtered over time. At this time, it will form a wall-like interception wall to continue to carry dust, while the air flow passes through the air inlet groove 71 and then through the arc-shaped filter cloth element 33 into the interior.

[0038] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
