[0002] With the development of science and technology, more and more high-power equipment has come into being. High-power equipment and energy storage devices (such as batteries) tend to generate a lot of heat during operation. If the heat accumulates, it may cause safety hazards. In order to dissipate heat in time, cooling equipment is usually configured.

[0003] There are two main ways to dissipate heat for cooling equipment: water cooling and air cooling. For some scenarios that require the storage of large amounts of electrical energy, multiple groups of batteries are usually placed in containers, and air cooling equipment is installed in the containers to dissipate heat for the batteries so that they can operate normally.

[0004] Since there are usually multiple battery packs installed in a container and the space between the battery packs is small, when the air-cooled cold source dissipates heat inside the box, the airflow may not easily reach between the battery packs, resulting in uneven heat dissipation. Even if the cooling capacity of the air-cooled cold source is increased, it is difficult to improve the heat dissipation effect in the narrow space, and there is a risk of excessive temperature difference between the batteries.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] See also Figure 1 The utility model provides a heat dissipation device, including a cold source 1 and a heat dissipation assembly 2. The cold source 1 is used to cool down the heat dissipation equipment; the heat dissipation assembly 2 includes a gas driving member 21, an ejection pipeline main path 22 and a plurality of ejection pipeline branches 23. The gas driving member 21 is arranged toward the air outlet end of the cold source 1. All ejection pipeline branches 23 are connected to the ejection pipeline main path 22. One end of the ejection pipeline main path 22 is connected to the gas driving member 21. The ejection pipeline branch 23 is provided with an air outlet 231 (see Figure 3 ), used for air cooling and heat dissipation in the narrow space between the heat dissipation devices. Among them, the cold source 1 is an air conditioner, and the gas driving component 21 is an air pump.

[0035] In this embodiment, a plurality of air outlets 231 are provided on both sides of an ejection pipe branch 23 in the length direction, the plurality of ejection pipe branches 23 are arranged in parallel, and one end of the ejection pipe branch 23 away from the ejection pipe main path 22 is closed.

[0036] In this way, under the action of the gas driving component 21, the low-temperature air output from the air outlet of the cold source 1 can enter the injection pipe branch 23 through the injection pipe main path 22, and enter the narrow space through the air outlet 231, thereby achieving the effect of heat dissipation in the narrow space. There is no need to increase the cooling capacity of the cold source 1, thereby improving the heat dissipation efficiency and saving energy.

[0037] Further, see Figure 2The main path 22 of the ejection pipeline includes a first main path 221 and a second main path 222. The horizontal first main path 221 is connected to the gas driving component 21. A plurality of vertical second main paths 222 are provided. One end of the same side of the plurality of second main paths 222 is connected to the first main path 221, and one end of the same side of the ejection pipeline branch 23 is connected to the second main path 222.

[0038] See also Figure 2 In some embodiments, the ejection pipeline branch 23 is detachably connected to the ejection pipeline main path 22. In this embodiment, the ejection pipeline branch 23 is detachably connected to the second main path 222 and is evenly distributed along the length direction of the second main path 222.

[0039] It can be understood that the position of the ejector pipe branch 23 on the ejector pipe main line 22 can be adjusted according to the position of the device to be cooled. In this embodiment, the ejector pipe branch 23 extends into the narrow space between adjacent devices to be cooled.

[0040] In this way, according to the location of the equipment to be cooled, by installing or removing the ejector pipe branch 23 on the ejector pipe main line 22, the area that needs to be cooled can be flexibly controlled, and the ejector pipe branch 23 near the area that does not need to cool can be reduced. This can not only improve the heat dissipation efficiency, but also effectively utilize air cooling energy and reduce energy waste.

[0041] See also Figure 2 In some embodiments, the heat dissipation component 2 also includes a connecting piece (not shown in the figure), and the ejection pipe branch 23 is connected to the ejection pipe main line 22 through the connecting piece. The heat dissipation component 2 also includes a control plug (not shown in the figure), which is detachably connected to the ejection pipe branch 23 and is used to block the air outlet 231.

[0042] In this embodiment, the connecting piece is a spiral plug, and the outer walls at both ends of the spiral plug are provided with threads. The second main path 222 is provided with one end facing the spiral plug, and the end of the injection pipe branch 23 is provided with threads. The spiral plug is connected to the injection pipe main path 22, and then one end of the injection pipe branch 23 is connected to the spiral plug, so as to connect the injection pipe main path 22 and the injection pipe branch 23; the diameter of one end of the control plug is matched with the diameter of the air outlet 231, so that after the control plug is inserted into the air outlet 231, the airflow inside the injection pipe branch 23 cannot be transported to the outside through the air outlet 231.

[0043] Furthermore, the control plug may also be connected to a connector to seal the corresponding connector after the ejector pipe branch 23 is removed.

[0044] In this way, the connecting piece can quickly connect the main ejection pipe 22 and the ejection pipe branch 23, making it easy to disassemble and assemble the ejection pipe branch 23 according to actual needs, thereby improving the flexibility of the heat dissipation device in dissipating heat to the heat dissipation equipment and improving the heat dissipation efficiency; by sealing the air outlet 231 with the control plug, it is possible to control the connectivity between each air outlet on the ejection pipe branch 23 and the outside world, thereby improving flexibility.

[0045] It can be understood that the main ejection pipe 22 and the branch ejection pipe 23 can also be detachably connected by other means. For example, the outer wall of the ejection pipe branch 23 at one end facing the main ejection pipe 22 is provided with a thread, and the main ejection pipe 22 is provided with a corresponding threaded hole, so that the branch ejection pipe 23 is threadedly connected to the main ejection pipe 22. The connection method between the main ejection pipe 22 and the branch ejection pipe 23 can be adjusted according to actual needs, and the position of the branch ejection pipe 23 can be flexibly adjusted, which will not be elaborated here; the shape and material of the connecting part can be adjusted according to actual needs.

[0046] See also Figure 3 In some embodiments, the output end of the gas driving member 21 is connected to a separator (not shown in the figure) for separating nitrogen from the air. The heat dissipation assembly 2 also includes a storage tank 24, the output end of the separator is connected to the storage tank 24, and the main ejection pipeline 22 is connected to the inside of the storage tank 24 for outputting the nitrogen inside the storage tank 24.

[0047] Among them, see Figure 1 The gas driving member 21 is connected to a motor 211 for driving the gas driving member 21 to work; the gas driving member 21 is connected to a storage tank 24 through a pipeline for delivering nitrogen to the storage tank 24 for storage. The storage tank 24 is a high-pressure tank, and a valve for controlling gas output is provided on the storage tank 24.

[0048] In this way, under the action of the separation element, the nitrogen in the low-temperature air output by the gas driving element 21 is separated and transported to the storage tank 24, and the high-pressure nitrogen output from the storage tank 24 can be transported to the narrow space to be cooled through the air outlet 231, which can not only improve the heat dissipation efficiency, but also due to the non-flammable nature of nitrogen, it can also form a relatively stable environment around the equipment to be cooled, avoiding dangerous situations such as fire and explosion due to temperature accumulation.

[0049] See also Figure 3 In some embodiments, the heat dissipation device further includes a pressure gauge 3 , which is connected to the storage tank 24 and is used to display the air pressure in the storage tank 24 .

[0050] In this way, the pressure of the nitrogen in the storage tank 24 can be known by observing the pressure gauge 3. When the pressure is low, it means that the nitrogen storage amount is small, and the gas driving component 21 needs to be opened to continue to transport the external nitrogen to the storage tank 24. When the nitrogen pressure in the storage tank 24 reaches the required range, the valve on the storage tank 24 is opened, so that the high-pressure and low-temperature nitrogen can quickly cool the narrow space through the outlet, thereby improving the cooling effect.

[0051] See also Figure 3 In some embodiments, the separation element is a molecular membrane, which is connected to the output end of the gas driving element 21 and is used to separate nitrogen from the air.

[0052] In this way, the molecular membrane can separate the low-temperature air output from the output end of the gas driving component 21, so that the non-flammable and stable nitrogen is transported to the inside of the storage tank 24 through the separation component.

[0053] It is understandable that the separation element may also be other structures, such as a nitrogen generator. The specific structure of the separation element can be adjusted according to actual needs, as long as it can separate nitrogen from the air, and no further examples are given here.

[0054] See also Figure 4 The utility model also provides an air-cooled container, including a box body 4 and a heat dissipation device. The box body 4 is provided with a placement cavity 41 for placing the device to be cooled, a refrigeration cavity 42 for placing the cold source 1, and a heat dissipation cavity 43 for placing the heat dissipation device. The placement cavity 41, the refrigeration cavity 42, and the heat dissipation cavity 43 are interconnected. The device to be cooled is a battery; the cold source 1 is arranged on one side of the box body 4, and the air outlet end of the cold source 1 is arranged toward the top surface of the box body 4; the device to be cooled is arranged on the other side of the box body 4, and the heat dissipation device is arranged toward the top surface of the box body 4.

[0055] See also Figure 4 In some embodiments, the air-cooled container further includes a fan (not shown in the figure), which is arranged at the return air end of the cold source 1. The fan and the cold source 1 are both installed in the refrigeration cavity 42 to further drive the air flow in the box body 4.

[0056] In this way, by placing the equipment to be cooled, the cold source 1 and the heat dissipation device in different cavities, the mutual interference among the three can be reduced, and the fan can re-transport the air flowing through the equipment to be cooled to the inside of the cold source 1 to achieve circulating air cooling and reduce energy waste.

[0057] See also Figure 5 In some embodiments, the air-cooled container further includes a door 5 , which is connected to the box body 4 , and a heat dissipation hole 51 is opened at a position of the door 5 corresponding to the cold source 1 .

[0058] In this way, the heat dissipation holes 51 not only facilitate the heat generated by the cold source 1 itself to be transported to the outside of the box body 4, but also enable the outside air to be exchanged with the air inside the box body 4, so that the air inside the box body 4 can circulate.

[0059] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
