Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology, and in particular relates to a heat dissipation structure for the charging module of a charging pile. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. The development of the new energy vehicle industry is inseparable from charging piles, and the charging module is the core component of the DC charging equipment for new energy vehicles. It is the basic unit for realizing power conversion such as rectification, inversion, and filtering. Its main function is to convert the AC power in the power grid into DC power that can be used to charge the battery. However, the charging module is the main heat-generating device in the charging pile. Poor ventilation in the cabinet may cause the charging module to overheat and trigger protection, affecting the normal use of the charging pile. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a heat dissipation structure for the charging module of a charging pile that has a reasonable structure, good heat dissipation effect, and quick and convenient filter cotton replacement.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A heat dissipation structure for a charging module of a charging pile includes a cabinet with a door on the front and a mounting cavity at the rear. Multiple charging modules are installed inside the mounting cavity. An air inlet and an air outlet are respectively opened on both sides of the mounting cavity. An air inlet window for sealing the air inlet is hinged to one side of the cabinet, and an air outlet window for sealing the air outlet is hinged to the other side of the cabinet. An air inlet filter is installed on the side of the air inlet window closest to the cabinet, and an air outlet filter is installed on the side of the air outlet window closest to the cabinet. An exhaust device is installed on the side of the air outlet filter device closest to the cabinet.

[0006] The following are further optimizations of the above technical solution by this utility model:

[0007] The air intake filter includes a first receiving box, which is fixedly connected to the air intake window. A first filter cotton is provided inside the first receiving box. A frame is provided on the side of the first receiving box away from the air intake window. A filter screen is fixedly connected inside the frame. The frame is fixedly connected to the first receiving box by multiple frame locking components.

[0008] Further optimization: The frame locking assembly includes a support plate, which is fixedly connected to the first receiving box. A mounting bracket is fixedly connected to the side of the support plate away from the air intake window, and a limit plate is provided between the mounting bracket and the support plate.

[0009] Further optimization: A pin is fixed to the end of the limiting plate near the mounting bracket. The pin passes through the mounting bracket and is threaded with a nut. A lever plate is integrally fixed to the end of the limiting plate away from the mounting bracket.

[0010] Further optimization: The exhaust air filtration device includes a second receiving box, which is fixedly connected to the exhaust window, and a second filter cotton is installed inside the second receiving box.

[0011] Further optimization: The exhaust system includes multiple exhaust fans, which are installed on the side of the second housing away from the air outlet.

[0012] This utility model features a rationally designed structure. An exhaust fan expels gas from the mounting cavity, carrying heat from the charging module. Simultaneously, cool air from outside enters the mounting cavity through the air inlet to cool the charging module. During this process, an intake filter effectively filters the air, preventing dust from entering the cabinet and affecting the normal operation of the components. An exhaust filter prevents dust from entering the cabinet when the exhaust fan is not operating. The frame locking assembly is simple in structure, convenient, and reliable. Loosening the nut and moving the lever moves the limiting plate away from the frame, allowing for quick removal of the frame and filter screen, and then removal of the first filter cotton, facilitating replacement of the first filter cotton and cleaning of the filter screen.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0018] like Figure 1-4As shown, a heat dissipation structure for a charging module of a charging pile includes a cabinet 1, a cabinet door 2 installed on the front side of the cabinet 1, an installation cavity provided at the rear of the cabinet 1, a plurality of charging modules 3 installed in the installation cavity, an air inlet and an air outlet respectively opened on both sides of the installation cavity, an air inlet window 4 hinged to the right side of the cabinet 1 for sealing the air inlet, and an air outlet window 5 hinged to the left side of the cabinet 1 for sealing the air outlet.

[0019] In addition to this embodiment, the air inlet 4 can also be located on the left side of the cabinet 1, and the air outlet 5 can also be located on the right side of the cabinet 1.

[0020] An air intake filter 6 is installed on the side of the air intake window 4 near the cabinet 1, and an air exhaust filter is installed on the side of the air exhaust window 5 near the cabinet 1. An exhaust device is installed on the side of the air exhaust filter near the cabinet 1.

[0021] The exhaust system includes three exhaust fans.

[0022] In addition to this embodiment, the number of exhaust fans 8 can also be one, two, or more than three.

[0023] With this design, the exhaust fan 8 expels the gas from the mounting cavity, carrying the heat emitted by the charging module with it. At the same time, cool air from outside enters the mounting cavity through the air inlet 4 to cool the charging module. During the process of the cool air entering the mounting cavity through the air inlet 4, the air intake filter 6 effectively filters the air, preventing dust from entering the cabinet 1 and affecting the normal operation of the components inside the cabinet 1. The exhaust filter also prevents dust from outside the cabinet from entering the cabinet 1 when the exhaust fan 8 is not in operation.

[0024] The air intake filter device 6 includes a first receiving box 601, which is fixedly connected to the air intake window 4. A first filter cotton is provided inside the first receiving box 601. An opening for taking out and putting in the first filter cotton is opened on the side of the first receiving box 601 away from the air intake window 4. A frame 602 is provided on the side of the first receiving box 601 away from the air intake window 4. A filter screen 603 is fixedly connected inside the frame 602. The frame 602 and the filter screen 603 are used together to block the opening. The frame 602 is fixedly connected to the first receiving box 601 by four frame locking components 604.

[0025] In addition to this embodiment, the number of frame locking components 604 can be four or more.

[0026] If the first filter cotton in the first housing box 601 absorbs too much dust, it will clog the pores and affect the passage of air. Since the charging pile usually works outdoors, the first filter cotton needs to be replaced frequently, and the filter screen 603 also needs to be cleaned regularly. The frame locking component 604 facilitates the replacement of the first filter cotton and the cleaning of the filter screen 603.

[0027] The frame locking assembly 604 includes a support plate 6041, which is fixedly connected to the first receiving box 601. A mounting bracket 6042 is fixedly connected to the side of the support plate 6041 away from the air intake window 4. A limiting plate 6043 is provided between the mounting bracket 6042 and the support plate 6041. The frame 602 is disposed between the limiting plate 6043 and the first receiving box 601. The limiting plate 6043 is used to fix the frame 602 and the first receiving box 601 together, thereby fixing the first filter cotton in the first receiving box 601.

[0028] A pin 6044 is fixedly connected to one end of the limiting plate 6043 near the mounting bracket 6042. The pin 6044 passes through the mounting bracket 6042 and is threaded with a nut. A lever plate 6045 is integrally fixed to one end of the limiting plate 6043 away from the mounting bracket 6042.

[0029] This design results in a simple and reliable frame locking assembly 604. Loosening the nut and moving the lever 6045 allows the limiting plate 6043 to move away from the frame 602, thus quickly removing the frame 602 and the filter screen 603, and then taking out the first filter cotton. Furthermore, the mounting bracket 6042, the limiting plate 6043, and the lever 6045 are all sheet metal parts, which greatly reduces production costs.

[0030] The exhaust filtration device includes a second receiving box 7, which is fixedly connected to the exhaust window 5, and a second filter cotton is provided inside the second receiving box 7.

[0031] The exhaust fan 8 is installed on the side of the second housing 7 away from the air outlet 5.

[0032] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
