Description

Technical Field

[0001] This patent application relates to the field of energy storage technology, and in particular to an air duct structure for an energy storage cabinet liquid-cooled unit. Background Technology

[0002] A liquid chiller is a device that uses liquid circulation to achieve refrigeration. Its principle is to absorb and release heat through the evaporation and condensation of the liquid, thereby reducing the temperature of the object being cooled. The basic idea of ​​its refrigeration principle is to achieve heat transfer by continuously circulating and changing the state of the refrigerant. By absorbing heat from the object being cooled and releasing it into the outside air (the absorption and release process is carried out by the built-in fan of the liquid chiller), the temperature of the object being cooled is reduced. It has high refrigeration efficiency and flexibility.

[0003] Currently, the air ducts for liquid-cooled chiller units in energy storage cabinets typically house the chiller unit inside the equipment, with exhaust vents at the rear. This creates a distance between the chiller unit and the exhaust vents, causing the built-in fan to expel heat, resulting in hot air swirling inside the enclosure and failing to escape. This leads to the entire enclosure overheating. It also hinders the intake of cool air at the front of the chiller unit. Therefore, we propose a new air duct structure for liquid-cooled chiller units within the energy storage cabinet. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this patent application is to provide an air duct structure for an energy storage cabinet liquid cooling unit to solve the problems of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A liquid-cooled unit air duct structure for an energy storage cabinet includes an energy storage cabinet. A partition is installed inside the energy storage cabinet. A liquid-cooled unit is placed on the upper end of the partition. Several energy storage batteries are installed at the bottom of the inner cavity of the energy storage cabinet, located below the partition. The circulation pipe of the liquid-cooled unit passes through the partition and is connected to the several energy storage batteries. The partition separates the liquid-cooled unit from the energy storage batteries to improve liquid cooling efficiency.

[0007] Furthermore, a fan shroud is installed on the partition plate. One end of the fan shroud is connected to the air outlet of the liquid cooling unit, and the other end of the fan shroud is connected to the cabinet door on the side wall of the energy storage cabinet. An exhaust hole is provided on the cabinet door.

[0008] Furthermore, the cross-sectional area of ​​the shroud is larger than the cross-sectional area of ​​the liquid cooler unit's air outlet, so that the shroud can be fitted onto the air outlet of the liquid cooler unit.

[0009] Furthermore, a waistline hole is provided on the bottom wall of the hood, and a positioning threaded sleeve is connected to the partition plate. After the positioning threaded sleeve passes through the waistline hole, it is locked by screws to fix the hood to the partition plate.

[0010] Furthermore, a fixing device for locking the liquid cooling unit is installed on the upper end of the partition away from the shroud.

[0011] Furthermore, the fixing device includes two vertical plates symmetrically connected to the upper end of the partition on the side away from the shroud. A connecting plate with its bottom higher than the top of the liquid cooler unit is connected between the two vertical plates. A locking plate protruding outward is connected to the side of the vertical plate away from the liquid cooler unit. After the liquid cooler unit is placed, the liquid cooler unit is locked by bolts passing through the locking plate.

[0012] Furthermore, a bent plate is integrally connected to the top of the connecting plate, and a threaded hole is opened on the horizontal surface of the bent plate. The bent plate is locked to the inner top wall of the energy storage cabinet by threaded nails passing through the threaded hole.

[0013] Furthermore, the partition plate is provided with several through holes for the circulation pipeline of the liquid cooling unit to pass through.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the air duct structure of the liquid cooling unit of this energy storage cabinet separates the liquid cooling unit and the energy storage battery through the partition. The liquid cooling unit directly exhausts the heat of the energy storage battery to the outside of the energy storage cabinet through the fan cover, and the hot air formed will not swirl inside the cabinet and cannot escape.

Figure 1-3 The system includes an energy storage cabinet 1, a partition 2, a liquid-cooled unit 3, a fan shroud 4, and a fixing device 5. The partition 2 is installed inside the energy storage cabinet 1. The liquid-cooled unit 3 and the fan shroud 4 are installed on the upper part of the partition 2. The air outlet of the liquid-cooled unit 3 is connected to the fan shroud 4. The cross-sectional area of ​​the fan shroud 4 is larger than the cross-sectional area of ​​the air outlet of the liquid-cooled unit 3 so that the fan shroud 4 can be fitted onto the air outlet position of the liquid-cooled unit 3. The fixing device 5 is located on the upper part of the partition 2 away from the fan shroud 4 and is used to lock the liquid-cooled unit 3 to prevent the liquid-cooled unit 3 from shifting during operation. Several energy storage batteries located below the partition 2 are installed at the bottom of the inner cavity of the energy storage cabinet 1. Figure 5 As shown, the partition 2 has several through holes 21. The circulation pipe of the liquid cooling unit 3 passes through the through holes 21 on the partition 2 and is connected to several energy storage batteries. The partition 2 separates the liquid cooling unit 3 from the energy storage batteries. The liquid cooling unit 3 directly exhausts the heat of the energy storage batteries to the outside of the energy storage cabinet 1 through the fan shroud 4. The hot air formed will not swirl inside the cabinet and will not escape, which is used to improve the liquid cooling efficiency of the energy storage batteries.

[0026] It should be noted that, as Figure 2 and Figure 3As shown, the end of the shroud 4 away from the liquid cooling unit 3 is connected to the cabinet door 11 on the side wall of the energy storage cabinet 1, and the cabinet door 11 is provided with an exhaust hole; the side of the energy storage cabinet 1 away from the cabinet door 11 is provided with an air inlet hole, and dustproof nets are installed at both the air inlet hole and the exhaust hole to prevent dust and other debris from entering the energy storage cabinet 1 and affecting the service life of the equipment. The installation of the dustproof nets is well known to those skilled in the art and will not be described in detail here.

[0027] In some examples, see Figure 4 The fixing device 5 includes two vertical plates 51 and a connecting plate 52, symmetrically connected to the upper end of the partition 2 on the side away from the fan shroud 4. The connecting plate 52 is connected between the two vertical plates 51, and the bottom of the connecting plate 52 is higher than the liquid cooling unit 3. A locking plate 53 protruding outward is connected to the side of the vertical plates 51 away from the liquid cooling unit 3. After the liquid cooling unit 3 is placed, the liquid cooling unit 3 is locked by bolts passing through the locking plate 53. The locking plate 53 is as follows: Figure 7 As shown.

[0028] As a preferred embodiment of this case, the top of the connecting plate 52 is integrally connected with a bent plate, and a threaded hole is opened on the horizontal surface of the bent plate. The bent plate is locked to the inner top wall of the energy storage cabinet 1 by threaded nails passing through the threaded hole, thereby increasing the strength of the structure.

[0029] In some examples, see Figure 6 The bottom wall of the wind shield 4 has a waistline hole 41, such as Figure 5 As shown, a positioning threaded sleeve 22 is connected to the partition plate 2. After the positioning threaded sleeve 22 passes through the waistline hole 41, it is locked by screws to fix the wind cover 4 on the partition plate 2. The wind cover 4 is installed and positioned accurately.
