Description

Technical Field

[0001] This utility model relates to the field of heat dissipation, and in particular to the heat dissipation structure of a generator set. Background Technology

[0002] Server racks are typically made of cold-rolled steel or alloy and are used in industrial and commercial energy storage cabinets to store power modules. They provide protection for the stored equipment, shield against electromagnetic interference, and allow for orderly and neat arrangement of equipment, facilitating future equipment maintenance.

[0003] When the equipment inside the cabinet is dissipating heat, the heat of the equipment is partially dissipated by a fan drawing in cool air from one side of the cabinet and then blowing the heated air out from the other side of the cabinet. This method of heat dissipation is inefficient and noisy. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a low-noise heat dissipation structure for the unit.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] The heat dissipation structure of the unit includes a cabinet and equipment installed inside the cabinet. The cabinet has an air inlet and a side panel. The side panel has a hollow structure and forms an air supply channel inside the side panel. The air supply channel extends vertically. The side panel has a first air inlet and a first air outlet. The first air outlet is located at the top of the cabinet. The air supply channel is connected to the first air inlet and the first air outlet. The bottom of the equipment has a second air inlet, and the side of the equipment has a second air outlet. The air entering through the air inlet of the cabinet enters the equipment through the second air inlet and flows from the second air outlet of the equipment through the first air inlet to the air supply channel, flowing vertically along the air supply channel until it is discharged from the first air outlet.

[0007] Furthermore, the cabinet also includes a door panel, and the air inlet is disposed on the door panel.

[0008] Furthermore, the door panel is rotatably connected to the side panel, and the air inlet is located at the bottom of the door panel.

[0009] Furthermore, the air inlet has a louvered structure.

[0010] Furthermore, the cabinet also includes a base plate, and the air inlet is disposed on the base plate.

[0011] Furthermore, the cabinet also includes support feet, which are fixed to the bottom of the base plate to suspend the base plate.

[0012] Furthermore, there are three side plates, which respectively form three air supply channels. The three sides of the device are provided with a second air inlet, and the three second air inlets correspond to the three air supply channels respectively.

[0013] Furthermore, the side panel includes an inner panel and an outer panel, with the air supply channel formed between the inner panel and the outer panel, and the first air inlet is disposed on the inner panel.

[0014] Furthermore, the heat dissipation structure of the unit also includes multiple mounting plates, which are fixed to the side plate to form multiple mounting positions inside the cabinet. The equipment is located in the mounting positions, and the number and position of the first air inlets on the side plate correspond to the mounting positions.

[0015] Furthermore, the side plate also includes a reinforcing plate, which is fixedly connected to the inner plate and the outer plate.

[0016] Compared to existing technologies, the heat dissipation structure of this utility model features a hollow side panel with an internal air supply channel extending vertically. The side panel has a first air inlet and a first air outlet, with the first air outlet located at the top of the cabinet. The air supply channel connects to both the first air inlet and the first air outlet. A second air inlet is located at the bottom of the equipment, and a second air outlet is located on the side of the equipment. Air entering through the cabinet's air inlet enters the equipment through the second air inlet and flows from the second air outlet through the first air inlet to the air supply channel. The air flows vertically along the air supply channel until it is discharged from the first air outlet. Through this design, the heat from the equipment is discharged from the top of the cabinet, achieving heat dissipation while minimizing noise. Attached Figure Description

[0027] See also Figure 1 as well as Figure 2 The heat dissipation structure of this application includes a cabinet 10, a mounting plate 30, and multiple devices 40. The cabinet 10 has an internal receiving space 20 for housing the devices 40. The mounting plate 30 is fixed inside the cabinet 10, so that the receiving space 20 forms multiple mounting positions 21, and each mounting position 21 is used to install one device 40. The multiple mounting positions 21 are arranged vertically.

[0028] The cabinet 10 is provided with an air inlet 110 for introducing cold air. Specifically, the cabinet 10 includes a door panel 11, a side panel 12, a bottom panel 13, a top panel 14, and support legs 15. The door panel 11 is movably mounted on the side panel 12 to facilitate the installation of the equipment 40 inside the cabinet 10. Preferably, the door panel 11 is rotatably mounted on the side panel 12. In this embodiment, the air inlet 110 is located at the bottom of the door panel 11 and has a louvered structure. In other embodiments, the air inlet 110 can also be located on the bottom panel 13, allowing air to enter from the bottom panel 13. In this case, support legs 15 are provided at the bottom of the bottom panel 13 to suspend the bottom panel 13, facilitating air entry.

[0029] An air supply channel 122 is formed within the side panel 12, extending vertically to allow heat from the equipment 40 to be exhausted from the top of the cabinet 10, reducing noise. Specifically, each side panel 12 includes an outer panel 120, an inner panel 121, and a reinforcing plate, with the outer panel 120 and the inner panel 121 forming the air supply channel 122. The reinforcing plate is fixed to the outer panel 120 and the inner panel 121, increasing the strength of the side panel 12. A first air inlet 123 is provided on the inner panel 121, and the position of the first air inlet 123 corresponds to the mounting position 21, allowing air flowing from the second air outlet 42 of the equipment 40 to enter the air supply channel 122 through the first air inlet 123. The number of first air inlets 123 is the same as the number of mounting positions 21. A first air outlet 124 is provided at the top of the side panel 12, which exhausts air from the air supply channel 122.

[0030] Mounting plates 30 are fixed to the inner plate 121, and multiple mounting plates 30 are arranged in pairs for mounting equipment 40. Multiple devices 40 inside the cabinet 10 are arranged vertically.

[0031] Please continue reading. Figure 3 as well as Figure 4 The device 40 has a second air inlet 41 at its bottom, which has a mesh structure. The device 40 also has a second air outlet 42 on its side, which also has a mesh structure. The cooling fan 43 inside the device 40 draws in cool air through the second air inlet 41 at the bottom and exhausts it through the second air outlet 42 on the side. Specifically, the device 40 has second air outlets 42 on both sides and the back side, and these second air outlets 42 correspond to the first air inlet 123.

[0032] Please continue reading Figure 5 as well as Figure 6When the device 40 is working, it is installed in the mounting position 21 of the housing space 20 and the door panel 11 is closed. At this time, cold air enters the housing space 20 from the air inlet 110 and enters the cooling fan 43 from the second air inlet 41 at the bottom of the device 40. After heat exchange, the air flows out from the second air outlet 42, passes through the first air inlet 123 and flows into the air supply channel 122. It moves upward along the air supply channel 122 until it is discharged from the first air outlet 124. Through the above design, the heat of the device 40 is discharged from the top of the cabinet 10. While achieving heat dissipation, the noise is low.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model.
