Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of energy storage cabinets, in particular to an air inlet and outlet heat dissipation device for an energy storage cabinet and an energy storage cabinet. Background Art

[0002] In recent years, with the rapid development of the new energy industry, lithium batteries are widely used in the energy storage industry, and the development process of energy storage cabinets is also accelerating. All the electrical components involved inside the energy storage cabinet have relatively high requirements for heat dissipation. This requires the heat dissipation structure to perform air inlet and outlet heat dissipation on the electrical components inside the cabinet, and thus relatively important requirements are imposed on the heat dissipation structure.

[0003] In the related art, the internal heat dissipation air path of the energy storage cabinet is relatively complex, and it is necessary to set up fans to assist in order to achieve the purpose of heat dissipation. However, the fans occupy the internal space of the energy storage cabinet, increasing the space size of the energy storage cabinet. Summary of the Utility Model

[0004] In view of this, the utility model provides an air inlet and outlet heat dissipation device for an energy storage cabinet and an energy storage cabinet, so as to solve the problem that the fans occupy the internal space of the energy storage cabinet and increase the space size of the energy storage cabinet.

[0044] Below in conjunction with Figures 1 to 8 , describe the embodiments of the present utility model.

[0045] According to an embodiment of the present utility model, on the one hand, there is provided an air inlet and outlet heat dissipation device for an energy storage cabinet. The energy storage cabinet includes a ventilation door panel 100 and a ventilation rear panel 200 which are arranged opposite to each other. An electrical component 300 to be cooled is arranged at an interval between the ventilation door panel 100 and the ventilation rear panel 200. The air inlet and outlet heat dissipation device of the energy storage cabinet includes a first ventilation protection structure 1, a second ventilation protection structure 2 and an air outlet duct 3. The first ventilation protection structure 1 is connected to the air inlet of the ventilation door panel 100. The projection of the electrical component 300 on the ventilation door panel 100 is within the range of the first ventilation protection structure 1. The second ventilation protection structure 2 is connected to the air outlet of the ventilation rear panel 200, and at least part of the projection of the second ventilation protection structure 2 on the ventilation door panel 100 is within the range of the first ventilation protection structure 1. The two ends of the air outlet duct 3 are respectively connected to one end of the electrical component 300 away from the first ventilation protection structure 1 and the second ventilation protection structure 2.

[0046] The projection of the electrical component 300 on the ventilation door panel 100 is within the range of the first ventilation protection structure 1, and at least part of the projection of the second ventilation protection structure 2 on the ventilation door panel 100 is within the range of the first ventilation protection structure 1, so that at least part of a linear air inlet and outlet heat dissipation channel can be formed among the first ventilation protection structure 1, the electrical component 300, the air outlet duct 3 and the second ventilation protection structure 2. The loss of the heat dissipation air is small, the heat dissipation path of the air inlet and outlet is short, and the heat dissipation efficiency is high. Moreover, the heat dissipation purpose can be achieved only by relying on natural wind without using a fan, which simplifies the air inlet and outlet heat dissipation device of the energy storage cabinet. It not only reduces the space occupied by the fan inside the energy storage cabinet, thus reducing the overall space size of the energy storage cabinet, but also reduces the cost of the air inlet and outlet heat dissipation device of the energy storage cabinet.

[0047] In one embodiment, the ventilation area of the second ventilation protection structure 2 is greater than or equal to the ventilation area of the electrical component 300.

[0048] The ventilation area of the second ventilation protection structure 2 being greater than or equal to the ventilation area of the electrical component 300 can meet the requirements of the heat dissipation air volume and ensure the heat dissipation air outlet effect.

[0049] In one embodiment, the electrical component 300 includes a first side wall arranged toward the ventilation door plate 100 and a second side wall 301 arranged toward the ventilation rear plate 200, a first ventilation area is provided below the first side wall, and a plurality of first ventilation openings are provided in the first ventilation area; a second ventilation area is provided below the second side wall 301, and a plurality of second ventilation openings 302 are provided on the second ventilation area; the first ventilation area and the second ventilation area are arranged opposite to each other, and the first ventilation openings are connected to the second ventilation openings 302; the projection of the first ventilation area on the ventilation door plate 100 is located within the range of the first ventilation protective structure 1; the projection of the second ventilation area on the ventilation rear plate 200 is located within the range of the second ventilation protective structure 2.

[0050] The first ventilation area and the second ventilation area are arranged opposite to each other, and the projection of the first ventilation area on the ventilation door plate 100 is located within the range of the first ventilation protection structure 1, and the projection of the second ventilation area on the ventilation rear plate 200 is located within the range of the second ventilation protection structure 2, so that the first ventilation protection structure 1, the first ventilation area, the second ventilation area and the second ventilation structure are arranged correspondingly in sequence, and a linear inlet and outlet air heat dissipation channel is formed. The first ventilation area and the second ventilation area of the electrical component 300 are both completely located in the linear inlet and outlet air heat dissipation channel, which has little loss of heat dissipation air, a short heat dissipation path for the inlet and outlet air, and high heat dissipation efficiency; and the heat dissipation purpose can be achieved by natural wind without the help of a fan, which simplifies the inlet and outlet air heat dissipation device of the energy storage cabinet, reduces the space inside the energy storage cabinet occupied by the fan, thereby reducing the space size of the overall energy storage cabinet; and reduces the cost of the inlet and outlet air heat dissipation device of the energy storage cabinet.

[0051] In one embodiment, the air outlet duct 3 includes a first duct section 31 and a second duct section 32; one end of the first duct section 31 is connected to the second side wall 301, and the area of the flow section of the first duct section 31 gradually decreases in the direction away from the electrical component 300; one end of the second duct section 32 is connected to the other end of the first duct section 31, and the other end is connected to the second ventilation protection structure 2.

[0052] The area of the flow cross-section of the first air duct section 31 gradually decreases in the direction away from the electrical component 300, which can increase the pressure of the heat dissipation air, increase the speed of the heat dissipation air, and thus improve the effect of the heat dissipation air; the setting of the second air duct section 32 can limit the pressurization effect of the first air duct section 31 to prevent excessive pressurization from causing a decrease in the heat dissipation air volume.

[0053] In one embodiment, the second air duct section 32 is an inclined air duct, and the second air duct section 32 is inclined downward in a direction away from the first air duct section 31 .

[0054] The second air duct section 32 can guide the heat dissipation air outlet, facilitating the heat dissipation air outlet.

[0055] In one embodiment, the first interval between the electrical component 300 and the first ventilation protection structure 1 is smaller than the second interval between the electrical component 300 and the second ventilation protection structure 2.

[0056] The first interval being smaller than the second interval can make the electrical component 300 closer to the first ventilation protection structure 1, enabling good air intake without setting up an air intake duct and with less air intake loss.

[0057] Specifically, the second interval is at least twice the first interval.

[0058] In one embodiment, both ends of the air outlet duct 3 are adhesively bonded to the electrical component 300 and the second ventilation protection structure 2 respectively through air duct cotton 4.

[0059] One end of the air outlet duct 3 being adhesively bonded to the electrical component 300 through air duct cotton 4 can make the air outlet duct 3 fit the surface of the electrical component 300 without gaps; the other end of the air outlet duct 3 being adhesively bonded to the second ventilation protection structure 2 through air duct cotton 4 can make the air outlet duct 3 fit the surface of the second ventilation protection structure 2 without gaps, forming a sealed heat dissipation channel for the air outlet duct 3 as a whole and preventing hot air from flowing back to other positions inside the energy storage cabinet.

[0061] The combined fixation of the ventilation sealing plate 21 and the stainless - steel insect and dust protection net 22 can achieve a certain degree of protection against insects, dust, and water splashes, meeting the requirements for the heat dissipation air volume.

[0062] Specifically, the ventilation sealing plate 21 is detachably connected to the air outlet through fastening structures such as bolts.

[0063] In one embodiment, the first ventilation protection structure 1 includes a ventilation shutter 11 and a metal plate type dust filter net 12; the ventilation shutter 11 is fixedly connected to the air inlet of the ventilation door panel 100; the metal plate type dust filter net 12 is fixedly connected to the ventilation shutter 11 and is located inside the energy storage cabinet.

[0064] The combined installation of the ventilation shutter 11 and the metal plate type dust filter net 12 can meet the requirements for waterproof and dust - proof of the protection level of the energy storage cabinet, and at the same time can also meet the requirements for the air intake volume.

[0065] Specifically, the ventilation louver 11 is detachably connected to the air inlet through a fastening structure such as bolts.

[0066] According to an embodiment of the present invention, on the other hand, there is also provided an energy storage cabinet, which includes a cabinet body 400, a ventilation door panel 100, a ventilation rear plate 200, electrical components 300, and the air inlet and outlet heat dissipation device of the above-mentioned energy storage cabinet; the ventilation door panel 100 is connected to the front of the cabinet body 400; the ventilation rear plate 200 is connected to the rear of the cabinet body 400 and is arranged opposite to the ventilation door panel 100; the electrical components 300 are arranged at intervals between the ventilation door panel 100 and the ventilation rear plate 200.
