Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a side-opening rainproof heat dissipation channel and its high-temperature distribution box. Background Technology

[0002] Power distribution boxes are mainly used to supply power and control electrical equipment. Due to the large number of connected devices and their long-term operation, they will generate a lot of heat. Therefore, they need to be used in conjunction with heat dissipation structures to suppress the accumulation of heat inside.

[0003] A search revealed a high-temperature resistant power distribution box (publication number: CN110137826B), whose structure includes a high-temperature resistant chassis structure, a door, and a window. The high-temperature resistant chassis structure has a door installed on the front and is connected by hinges, and the window is embedded in the front of the door. The high-temperature resistant chassis structure includes a chassis body, a lower water tank, an air outlet mechanism, a cover structure, and an air inlet mechanism. The lower water tank is horizontally located at the lower end of the chassis body, the air outlet mechanism is vertically installed on the right side of the chassis body and is mechanically connected, and the cover structure is horizontally installed on the top of the chassis body.

[0004] In existing technologies, the heat dissipation window is located on one side of the chassis and is always open. In the event of heavy rain with crosswinds, rainwater hitting the side wall of the chassis can easily enter the chassis through the window, affecting the normal operation of the electronic equipment inside the chassis and posing certain risks. However, using a semi-open heat dissipation channel will affect the heat dissipation inside the chassis, thus limiting the heat dissipation efficiency. There is room for optimization in balancing the heat dissipation and rainproof performance of existing chassis.

[0005] To address this, we propose a side-opening rainproof heat dissipation channel and its high-temperature distribution box. Utility Model Content

[0006] The present invention mainly addresses the technical problem of poor rain protection performance of normally open windows by providing a side-opening rainproof heat dissipation channel and its high-temperature power distribution box.

[0008] Air duct, the air duct has a square tube structure with a cavity;

[0009] A spacer assembly is installed inside the air duct cavity for rain protection. The spacer assembly includes a first guide fluid and a second guide fluid. A plurality of first and second guide fluids are arranged inside the air duct cavity, and the first and second guide fluids divide the air duct cavity to form a labyrinth channel.

[0010] In a preferred embodiment of this utility model, the first guide fluid is a square funnel, which is fixedly installed on the inner wall of the air guide pipe, and multiple smaller ports of the first guide fluid are distributed in the same direction.

[0011] In a preferred embodiment of this utility model, the second guide fluid is a rectangular plate, which is fixedly installed on the inner bottom surface of the air guide duct, and the top of the second guide fluid is at the same height as the bottom surface of the first guide fluid.

[0012] In a preferred embodiment of this invention, the second guide fluid extends obliquely toward the smaller port of the first guide fluid, and a second guide fluid is provided between two adjacent first guide fluids, with a gap between the two second guide fluids.

[0013] In a preferred embodiment of the present invention, two adjacent first guide fluids have overlapping portions, and the smaller port of one first guide fluid is inserted into the larger port of the adjacent first guide fluid, and the two first guide fluids do not contact each other.

[0014] In a preferred embodiment of this utility model, a baffle is fixedly installed on the outer wall of the air guide duct, and mounting holes for installation are provided at the four corners of the baffle.

[0015] A high-temperature distribution box includes an outer shell, a window for heat dissipation is provided on one side of the outer shell, and all the above-mentioned side-opening rainproof heat dissipation channels are provided on one side of the outer shell. The baffle is locked and fixed to the outer shell by screws, and the air duct opening faces the window.

[0016] Beneficial effects

[0017] This utility model provides a side-opening rainproof heat dissipation channel and its high-temperature power distribution box. It has the following beneficial effects:

[0018] 1. This side-opening rainproof heat dissipation channel and its high-temperature power distribution box, through multiple first and second guide fluids dividing the chamber of the air duct, the larger port of the first guide fluid is used for air intake, and the smaller port of the first guide fluid is used for exhaust. Hot air flows and is discharged from the larger port of the first guide fluid to the smaller port, which can guide the hot air to be discharged quickly out of the air duct.

At the same time, the multiple second guide fluids form a partition below the first guide fluid. The multiple first and second guide fluids form a tortuous labyrinth channel inside the air duct. While ensuring rapid heat dissipation, it can also prevent rainwater from entering due to the open design of the air duct, and the waterproof performance is also better.

[0019] 2. The side-opening rainproof heat dissipation channel and its high-temperature power distribution box have a U-shaped baffle plate. The baffle can be integrally formed with the air duct. The air duct can be easily installed and fixed to the equipment through the mounting holes of the baffle.

[0027] A side-opening rainproof heat dissipation channel and its high-temperature distribution box, such as Figure 1 As shown, it includes:

[0028] Air duct 10, the air duct 10 has a square tube structure with a cavity;

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a spacer assembly is disposed within the cavity of the air duct 10 for rain protection. The spacer assembly includes a first guide fluid 20 and a second guide fluid 21. A plurality of first guide fluids 20 and second guide fluids 21 are disposed within the cavity of the air duct 10, dividing the cavity of the air duct 10 into a labyrinthine passage. The first guide fluid 20 is a square funnel, fixedly installed on the inner wall of the air duct 10. The smaller ports of the plurality of first guide fluids 20 are distributed in the same direction. The second guide fluid 21 is a rectangular plate, fixedly installed on the inner wall of the air duct 10. The second guide fluid 21 is fixedly installed on the inner bottom surface of the air guide 10. The top of the second guide fluid 21 is at the same height as the bottom surface of the first guide fluid 20. The second guide fluid 21 extends obliquely toward the smaller port of the first guide fluid 20. A second guide fluid 21 is provided between two adjacent first guide fluids 20. There is a gap between the two second guide fluids 21. Two adjacent first guide fluids 20 have overlapping parts. The smaller port of one first guide fluid 20 is inserted into the larger port of the adjacent first guide fluid 20 and the two first guide fluids 20 do not contact each other.

[0030] In this design, the chamber of the air duct 10 is mainly divided by multiple first guide fluids 20 and second guide fluids 21. The larger port of the first guide fluid 20 is used to receive airflow, and the smaller port of the first guide fluid 20 is used for exhaust. Hot air flows from the larger port of the first guide fluid 20 to the smaller port and is discharged, which can guide the hot air to be discharged quickly from the air duct 10. Combined with the open design of the air duct 10, it can quickly dissipate heat in high-heat environments. At the same time, the multiple second guide fluids 21 form a partition below the first guide fluid 20. The multiple first guide fluids 20 and second guide fluids 21 make the interior of the air duct 10 form a tortuous labyrinth channel. While ensuring rapid heat dissipation, it can also prevent rainwater from entering due to the open design of the air duct 10, and the waterproof performance is also better.

[0031] like Figure 1 and Figure 2 As shown, a baffle 11 is fixedly installed on the outer wall of the air duct 10. Mounting holes for installation are provided at the four corners of the baffle 11. The baffle 11 is a U-shaped plate. The baffle 11 can be integrally formed with the air duct 10. The air duct 10 can be easily installed and fixed to the equipment through the mounting holes of the baffle 11.

[0032] like Figure 5As shown, a high-temperature distribution box includes a housing 30. A window for heat dissipation is opened on one side of the housing 30. All the aforementioned side-opening rainproof heat dissipation channels are provided on one side of the housing 30. The baffle 11 is locked and fixed to the housing 30 by screws. The opening of the air guide 10 faces the window. By setting the aforementioned side-opening rainproof heat dissipation channels and the baffle 11 being locked to the housing 30 by screws, the larger port of the first guide 20 faces the window. A sealing gasket can be installed between the baffle 11 and the housing 30. With the above structure, even if high-power electrical equipment is installed inside the housing 30, by installing a cooling fan inside the cabinet to exhaust air towards the window, hot air can be quickly discharged, suppressing heat accumulation. At the same time, it has outstanding rainproof performance. Even in the presence of crosswinds, the multiple first guides 20 and second guides 21 can prevent rainwater from entering the housing.

[0033] The working principle of this utility model is as follows: The air duct 10 is installed and fixed by screws passing through the mounting holes of the flange 11 and locking them to the outer casing 30. A cooling fan is installed inside the cabinet to exhaust air towards the window. The larger port of the first air duct 20 is for air intake, and the smaller port is for exhaust. Hot air flows from the larger port to the smaller port of the first air duct 20, guiding the hot air to quickly exit the air duct 10. Combined with the open design of the air duct 10, it can quickly dissipate heat in high-heat environments. Simultaneously, multiple second air ducts 21 form a partition below the first air duct 20. The multiple first and second air ducts 20 and 21 create a winding labyrinthine channel inside the air duct 10, ensuring rapid heat dissipation while also preventing rainwater from entering due to the constantly open design of the air duct 10, thus providing both heat dissipation and rainproof functions.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
