Description

Technical Field

[0001] This utility model relates to the field of radiator technology, and in particular to a radiator and a charging terminal. Background Technology

[0002] In electric vehicle charging terminals, an efficient heat dissipation system is crucial for stable operation. A common forced-air cooling solution involves creating ventilation holes in the equipment housing and installing a fan to draw in cool outside air, carrying away the heat generated by the heating elements. However, outside air contains dust, and dust accumulation inside the housing can lead to decreased heat dissipation efficiency, component corrosion, and even short circuits. Therefore, air filters are typically installed at the air inlet to filter dust. However, in current technology, the filter is installed directly inside the housing or attached to the inner wall. When replacing the filter, operators need to reach into the narrow space filled with electronic components and cables to remove and install it. This operation is highly susceptible to contact with live parts or damage to nearby components, posing a risk of electric shock and operational safety hazards, making filter replacement and maintenance extremely inconvenient. Utility Model Content

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 9As shown, a radiator according to one embodiment of the present invention includes: a housing 100, a sliding member 200, a ventilation device 400, and a locking member 500. The housing 100 is connected to a door that can be opened and closed for easy maintenance and repair. An air inlet 110 and an air outlet 120 are respectively provided on the right side and left side walls of the housing 100; the sliding member 200 is slidably disposed within the air inlet 110, and the sliding member 200 can slide left and right. A mounting cavity 201 is formed within the sliding member 200, and a filter element 300 is placed in the mounting cavity 201. The mounting cavity 201 has a replacement opening in a front-to-back direction, through which the filter element 300 can pass. The sliding member 200 has a working position and a maintenance position. When the sliding member 200 is in the working position, the replacement opening is located inside the housing 100; when the sliding member 200 is in the maintenance position, the replacement opening is located outside the housing 100. This means that when replacing the filter element 300, the operating space is completely isolated from the electrical and heating elements inside the housing 100, improving operational safety and avoiding the risk of electric shock or burns. The operator manually pushes the sliding member 200 to switch between the working and maintenance positions. A ventilation device 400 is connected to the sliding member 200 and is configured to drive outside air through the filter element 300 and into the housing 100. After entering the housing 100, the air dissipates heat from the interior of the housing 100 and is then discharged from the air outlet 120. The ventilation device 400 and filter element 300 are integrated within the sliding member 200, optimizing the internal space of the housing 100. The sliding member 200, filter element 300, and ventilation device 400 can be manufactured, tested, and replaced as a single module, facilitating inspection and maintenance. A locking member 500 is located within the housing 100 and is configured to secure the sliding member 200 when it is moved to the working and maintenance positions. The locking member 500 secures the sliding member 200 in both positions, ensuring that it does not shift due to vibration or airflow reaction forces in the working position. The air inlet 110 accurately aligns with the sliding member 200, reducing air leakage and ensuring efficient heat dissipation. Because the locking member 500 is located within the housing 100, the sliding member 200 cannot be pulled out from the outside during normal operation, thus preventing the theft of the filter element 300 from public areas. When in the maintenance position, the sliding member 200 can be stably held externally, facilitating the replacement of the filter element 300 with both hands. The filter element 300 replacement process is simplified as follows: the locking member 500 releases the fixing of the sliding member 200, the sliding member 200 is pulled out, the filter element 300 is replaced through the replacement opening, the sliding member 200 is pushed back, and the locking member 500 fixes the sliding member 200, thus improving the efficiency of filter element 300 replacement.

[0023] Reference Figures 5 to 7As shown, the sliding member 200 includes an outer panel 210 and an inner support plate 220, both made of aluminum alloy or alloy steel. The outer panel 210 and the inner support plate 220 are vertically aligned and parallel to each other. The upper ends of the outer panel 210 and the inner support plate 220 are connected by a top plate 230, which is welded to both. The lower ends of the outer panel 210 and the inner support plate 220 are connected by a bottom plate 240, which is welded to both. The mounting cavity 201 is formed by the outer panel 210, the inner support plate 220, the top plate 230, and the bottom plate 240. The outer panel 210 has multiple first flow holes 211, and the inner support plate 220 has multiple second flow holes 221. The ventilation device 400 is installed on the side of the inner support plate 220 away from the mounting cavity 201. The first flow holes 211 and the second flow holes 221 allow air to circulate on both sides of the filter element 300. The outer panel 210, inner support plate 220, top plate 230, and bottom plate 240 together form a robust frame, providing a closed and independent air intake duct for the internal filter element 300, ensuring filtration efficiency.

[0024] Reference Figure 6 and Figure 7 As shown, it can be understood that multiple rainproof sections 212 are provided on the side of the outer panel 210 away from the mounting cavity 201. The rainproof sections 212 are used to prevent rainwater from entering the first flow hole 211. The rainproof section 212 is a curved arc plate, and each first flow hole 211 is provided with a rainproof section 212. The arc plate forms an eaves shape, which effectively prevents rainwater, splashing water droplets, and even large condensate from directly entering the first flow hole 211, ensuring the normal operation of the equipment in rainy and snowy weather.

[0025] Reference Figures 5 to 7 As shown, both the top plate 230 and the bottom plate 240 are connected to the housing 100 via guide members 250. Four guide members 250 are symmetrically arranged, and they are linear guides installed using bolt connections. The slider, which mates with the linear guides, is bolted to the inside of the housing 100. Since the slider 200 is primarily subjected to gravity, it requires vertical support. Linear guide pairs, as high-precision standard components, are easy to procure and install. The symmetrical arrangement of the four linear guides ensures that the slider 200 operates extremely smoothly and stably during pushing and pulling, and can withstand its weight.

[0026] Reference Figure 3 , Figure 6 and Figure 7As shown, it is understood that the top plate 230 and the bottom plate 240 are bolted together with a stop 260. The stop 260 is bolted to the top plate 230 and the bottom plate 240, which is very simple to process and install, and has low manufacturing cost. The stop 260 can abut against the housing 100. The outer panel 210 is larger than the air inlet 110. The outer panel 210, the stop 260, and the side wall of the housing 100 work together to limit the travel of the sliding member 200. The purpose of limiting the travel of the sliding member 200 is to prevent the sliding member 200 from disengaging from the air inlet 110. This prevents accidents caused by the operator pulling the sliding member 200 out completely due to excessive force.

[0027] Reference Figure 2 and Figure 5 As shown, it can be understood that the portion of the slider 200 located within the housing 100 is bolted to a handle 270. The handle 270 provides a point of leverage for the operator to push or pull the slider 200. The handle 270 is ergonomically designed, allowing for a firm grip with the fingers, making the pushing and pulling motion smoother, and reducing the difficulty of operation and physical exertion.

[0028] Reference Figure 3 and Figure 8 As shown, the locking element 500 includes a pin 510 and a fixing part 520. The entire locking element 500 is composed of the pin 510 and the fixing part 520 with a hole, which has the advantages of low manufacturing cost, low failure rate, and long service life. The fixing part 520 is connected to the inner wall of the housing 100. The fixing part 520 has a socket 521, through which the pin 510 passes. The extension direction of the pin 510 is perpendicular to the movement direction of the slider 200. The fixing part 520 is located above the slider 200. Both the socket 521 and the pin 510 are vertically arranged. The pin 510 directly blocks the movement path of the slider 200 on the guide rail, providing a reliable locking force. The top plate 230 is provided with a working fixing hole 231 and a maintenance fixing hole 232. When the sliding member 200 is in the working position, the pin 510 is inserted into the working fixing hole 231 in a direction perpendicular to the movement of the sliding member 200 to resist the displacement tendency of the sliding member 200 caused by equipment vibration or accidental collision. When the sliding member 200 is in the maintenance position, the pin 510 is inserted into the maintenance fixing hole 232 in a direction perpendicular to the movement of the sliding member 200 to resist the displacement tendency of the sliding member 200 caused by equipment vibration or accidental collision.

[0029] Reference Figure 5As shown, the ventilation device 400 consists of three cooling fans arranged side by side. The ventilation device 400 is bolted to the inner support plate 220. The parallel arrangement of the three cooling fans improves both heat dissipation capacity and system reliability. If one cooling fan fails and stops operating, the other two can continue to work, maintaining basic heat dissipation and preventing overheating. For maintenance, the operator only needs to remove the stop block 260 to pull the sliding part 200 out of the housing 100, and then replace the fan outside the housing 100. This avoids the risk of electric shock or burns.

[0030] Reference Figure 9 As shown, it can be understood that side panels 130 are vertically welded to the inner wall of the housing 100, and the side panels 130 are used to guide the sliding member 200. Two side panels 130 are provided, located on the front and rear sides of the sliding member 200 respectively. The side panels 130 limit the forward and backward movement of the sliding member 200, ensuring that the sliding member 200 maintains a linear movement during pushing and pulling, and does not wobble back and forth. When the sliding member 200 is in the working position, the side panels 130 block the front and rear sides of the filter element 300, sealing the replacement opening, thus forming a complete airflow channel around the filter element 300. This ensures that the air entering the housing 100 must first pass through the filter element 300, guaranteeing filtration efficiency.

[0031] This utility model also provides a charging terminal, including a circuit element 600 and a heat sink, wherein the circuit element 600 is installed inside the housing 100. The specific structure of the circuit element 600 is prior art and will not be described in detail.

[0032] Operating Procedure: The operator manually pulls out the pin 510 located in the working fixing hole 231. Holding the handle 270 connected to the slider 200, smoothly push it outward from the air inlet 110 of the housing 100. When the stop 260 contacts the housing and cannot be pulled further, the slider 200 has reached the preset maintenance position. Insert the pin 510 into the maintenance fixing hole 232. At this point, the mounting cavity for the filter element 300 is completely located outside the housing. The operator can safely remove the old filter element 300 directly from the replacement opening. Place the new filter element 300 into the mounting cavity 201 and position it correctly. Push the slider 200 back to the working position. When the slider 200 reaches its innermost position and cannot be pushed further, it has reached the working position. At this point, insert the pin 510 into the corresponding working fixing hole 231 to lock it in place.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
