Description

Technical Field

[0001] The utility model relates to the technical field of energy storage devices, in particular to a top-mounted air conditioner for an energy storage cabinet and an energy storage cabinet. Background Art

[0002] With the increasing demand in the industrial and commercial energy storage market, industrial and commercial energy storage cabinets are gradually developing towards higher energy density, smaller floor area, more convenient installation and maintenance, etc. The demand for high energy density has caused an increase in heat generation per unit area of batteries inside industrial and commercial energy storage cabinets, resulting in an increasing demand for heat dissipation and cooling of the industrial and commercial energy storage cabinets. Therefore, industrial and commercial energy storage cabinets often use liquid cooling for heat dissipation.

[0003] The existing liquid cooling installation schemes for industrial and commercial energy storage cabinets mainly include two types. One is to add a compartment inside the energy storage cabinet to set up a liquid cooling air conditioner and separate it from the battery pack. However, the internal setting of the liquid cooling air conditioner will increase the floor area of the battery cabinet. At the same time, when the air conditioner fails, the whole system needs to be shut down and the air conditioner needs to be removed for maintenance, and the installation and maintenance are cumbersome. The other is to cancel one battery pack inside the energy storage cabinet and use this position to place the liquid cooling air conditioner. This will lead to a reduction in the number of battery packs and a decrease in the electricity storage capacity of the energy storage cabinet, that is, a decrease in energy density. When the air conditioner fails, it also needs to be shut down and the air conditioner needs to be removed for maintenance, and the installation and maintenance are cumbersome.

[0042] The following is a reference to Figures 1 to 6 introduce the overhead air conditioner 100 for the energy storage cabinet and the energy storage cabinet provided by the present utility model.

[0043] Please refer to Figures 1 to 3 , specifically, the overhead air conditioner 100 for the energy storage cabinet is arranged on the top of the energy storage cabinet. The overhead air conditioner 100 for the energy storage cabinet includes a housing 10 and a refrigeration structure. The refrigeration structure is arranged inside the housing 10; the refrigeration structure is communicated with the liquid cooling structure 310 of the battery pack 300 inside the energy storage cabinet, and the refrigeration structure is used to refrigerate the battery pack 300; wherein: at least one side wall of the housing 10 is provided with an air inlet 11 for the entry of external air; an air outlet 12 is opened on the top wall of the housing 10 for the outflow of hot air inside the housing 10 to reduce the heat conducted by the refrigeration structure.

[0044] In the overhead air conditioner 100 for the energy storage cabinet in this embodiment, by arranging the air outlet 12 on the top wall of the housing 10 and the air inlet 11 on the side wall of the housing 10, after the air enters from the air inlet 11, it absorbs the heat conducted by the refrigeration structure inside the housing 10 to form hot air and rises and flows out through the air outlet 12. Moreover, due to the principle that hot air rises, it can be ensured that the hot air will not flow back into the housing 10 again through the air outlet 12, ensuring the temperature of the working environment of the direct cooling structure and improving the refrigeration effect of the overhead air conditioner 100 for the energy storage cabinet. And by directly arranging the overhead air conditioner 100 for the energy storage cabinet on the top of the energy storage cabinet, it does not need to occupy the internal space of the energy storage cabinet, improving the space utilization rate, reducing the risk of liquid leakage and short circuit, improving the safety, and simplifying the maintenance steps, improving the maintenance convenience.

[0045] It can be understood that since the refrigeration structure is not directly communicated with the outside, and the multiple refrigeration devices included in the refrigeration structure are all waterproof structures, therefore, the air outlet 12 is arranged on the top wall of the housing 10, and there is no need to worry about the problem that rainwater enters and causes the refrigeration structure to fail to operate.

[0046] Moreover, the refrigeration structure includes refrigeration devices such as a compressor and a condenser, which can realize the cooling of the coolant, and they are all common structures in the art and will not be elaborated here.

[0047] Of course, for the liquid cooling structure 310 in the battery pack 300, it can be a liquid cooling plate structure, a liquid cooling pipeline structure, an integrated structure integrated with the box body of the battery pack 300 to form a flow channel, or immersion liquid cooling, etc. It only needs to satisfy the sufficient heat exchange between the coolant and the batteries inside the battery pack 300, and they are all common structures in the art and will not be elaborated here.

[0048] Optionally, the housing 10 is a metal structure, which is convenient for the heat dissipation of the overhead air conditioner 100 for the energy storage cabinet.

[0049] Please refer to Figure 4, optionally, the width of the housing 10 is less than the width of the energy storage cabinet, so that there is a gap between the top-mounted air conditioners 100 of two adjacent energy storage cabinets, thereby ensuring the communication between the air inlet 11 on the side wall of the housing 10 and the external air, and further ensuring the smooth intake of air for the top-mounted air conditioner 100 of the energy storage cabinet.

[0050] Please refer to Figures 1 to 3 , in some embodiments, the air outlet 12 includes a plurality of meshes 121 arranged at intervals to form a separation net; the meshes 121 are used to communicate the air inside and outside the housing 10, and the separation net is used to block the entry of sundries, so as to prevent larger objects such as leaves from falling into the interior of the housing 10 and affecting the operation of the refrigeration structure. Moreover, the air outlet 12 is directly formed on the housing 10 without adding additional structures, and the metal housing 10 is more conducive to heat dissipation.

[0051] In some embodiments, the air inlet 11 includes a frame structure and a plurality of grilles arranged at intervals. The grilles are arranged on the frame structure, and a plurality of adjacent grilles form an air inlet passage for the entry of air, so that the structure of the air inlet 11 has a certain function of blocking sundries. However, since the air inlet 11 is often used for the entry of air, some impurities may be mixed in when the air enters. Therefore, the top-mounted air conditioner 100 of the energy storage cabinet further includes a filter screen, which is installed at the air inlet 11 and is used to filter the air entering the housing 10, thereby realizing the filtering of impurities.

[0052] In some embodiments, a water outlet pipe 30 and a water return pipe 40 are further provided on the side wall of the housing 10. The two ends of the water outlet pipe 30 are respectively connected to the water outlet 21 of the refrigeration structure and the liquid inlet of the liquid cooling structure 310 of the battery pack 300. Specifically, one pipe orifice of the water outlet pipe 30 is connected to the water outlet 21 of the refrigeration structure, and the other pipe orifice of the water outlet pipe 30 is connected in parallel with the liquid inlets of the liquid cooling structures 310 of each battery pack 300; the two ends of the water return pipe 40 are respectively connected to the water return port 22 of the refrigeration structure and the liquid outlet of the liquid cooling structure 310 of the battery pack 300. Specifically, one pipe orifice of the water return pipe 40 is connected to the water return port 22 of the refrigeration structure, and the other pipe orifice of the water return pipe 40 is connected in parallel with the liquid outlets of the liquid cooling structures 310 of each battery pack 300. The above settings enable the refrigeration structure and the liquid cooling structures 310 of each battery pack 300 to form a circulation loop, so that the refrigeration structure cools the coolant and then transfers it to the liquid cooling structure 310 to cool and exchange heat with the battery pack 300, and then outputs the heat-exchanged coolant to the refrigeration structure for cooling and then proceeds to the next cycle, thereby ensuring the cooling and heat dissipation effect of the battery pack 300. Moreover, the liquid cooling structures 310 in each battery pack 300 are connected in parallel, which can make the cooled coolant flow evenly into each battery pack 300, so that the top-mounted air conditioner 100 of the energy storage cabinet cools and exchanges heat with each battery pack 300.

[0053] Optionally, a waterproof and sealed connection is provided between the water outlet pipe 30 and the water outlet 21, and a waterproof and sealed connection is provided between the water return pipe 40 and the water return port 22, thereby ensuring the sealing of the coolant circuit.

[0054] In some embodiments, the refrigeration structure further has an exhaust port 23. The exhaust port 23 is connected to the circulation pipeline of the refrigeration structure. The exhaust port 23 is used to evacuate the gas in the circulation pipeline of the refrigeration structure, improving the reliability of the cooling and heat dissipation of the refrigeration structure.

[0055] In some embodiments, the refrigeration structure further has a liquid injection and discharge port 24. The liquid injection and discharge port 24 is connected to the circulation pipeline of the refrigeration structure. The liquid injection and discharge port 24 is used for injecting or discharging the coolant in the circulation pipeline of the refrigeration structure, facilitating operations such as liquid injection and liquid replenishment inside the refrigeration structure.

[0056] In some embodiments, the housing 10 further has a plurality of suspension members 50. The suspension members 50 are used to connect to an external handling device. That is, when the rooftop air conditioner 100 of the energy storage cabinet is moved, it can be connected to the suspension members 50 through an external handling device and then the rooftop air conditioner 100 of the energy storage cabinet can be driven to move, facilitating the handling and installation by operators.

[0057] Specifically, generally there are multiple suspension members 50. The multiple suspension members 50 are distributed on the top wall of the housing 10, making the connection points between the rooftop air conditioner 100 of the energy storage cabinet and the outside more uniform. When the rooftop air conditioner 100 of the energy storage cabinet is moved and handled, the rooftop air conditioner 100 of the energy storage cabinet can be in a horizontal state by itself and will not be inverted or tilted to cause damage to the internal refrigeration structure.

[0058] Specifically, the suspension member 50 is selected as a lifting ring, which has a simple structure and is convenient for connecting to an external handling device.

[0059] In some embodiments, the housing 10 further has a plurality of fixing members 60. The fixing members 60 are used to connect to the energy storage cabinet, facilitating the installation of the rooftop air conditioner 100 of the energy storage cabinet.

[0060] Specifically, generally there are multiple fixing members 60. The multiple fixing members 60 are distributed on the side wall of the housing 10 to make the installation of the rooftop air conditioner 100 of the energy storage cabinet more stable.

[0061] Please refer to Figure 4 , in this embodiment, the rooftop air conditioner 100 of the energy storage cabinet further includes an electric control device 70. The electric control device 70 is arranged on the front side of the housing 10 and is electrically connected to the refrigeration structure. The electric control device 70 is used to detect and control the temperature, pressure, etc. of the refrigeration structure to make the refrigeration operation of the refrigeration structure stable. It can be understood that the specific structure of the electric control device 70 can be the one commonly used by those skilled in the art and is not specifically limited herein.

[0062] In some embodiments, the electronic control device 70 is provided with a waterproof and sealed connector, and the refrigeration structure is provided with a waterproof joint 25. The waterproof joint 25 is arranged on the housing 10, and the waterproof and sealed connector is electrically connected to the waterproof joint 25, so as to realize the electrical connection between the electronic control device 70 and the refrigeration structure. Moreover, the waterproof and sealed setting can ensure the waterproof and airtight performance of the waterproof joint 25 and the waterproof and sealed connector exposed outside, improving the reliability of the top-mounted air conditioner 100 of the energy storage cabinet.

[0063] In some embodiments, a heat dissipation window 71 is arranged on the outer shell of the electronic control device 70. The heat dissipation window 71 is used for dissipating heat of the internal structure of the electronic control device 70, thus preventing the heat generated by the electrical components inside the electronic control device 70 from not being dissipated, and improving the reliability of the electronic control device 70.

[0064] Please refer to Figure 5 and Figure 6 , this embodiment also provides an energy storage cabinet, which includes a cabinet body 200 and the top-mounted air conditioner 100 of the energy storage cabinet described in any of the above solutions. A plurality of battery packs 300 are arranged inside the cabinet body 200, and each battery pack 300 includes at least one liquid cooling structure 310; the top-mounted air conditioner 100 of the energy storage cabinet is arranged on the top of the cabinet body 200.

[0065] By directly arranging the top-mounted air conditioner 100 of the energy storage cabinet on the top of the energy storage cabinet, this energy storage cabinet does not need to occupy the internal space of the energy storage cabinet, improving the space utilization rate, reducing the risk of liquid leakage and short circuit, enhancing the safety, and can be directly carried out outside the cabinet body 200 during air conditioner maintenance without shutting down the entire energy storage cabinet, simplifying the maintenance steps and improving the maintenance convenience. Moreover, the liquid cooling structures 310 in each battery pack 300 are arranged in parallel, which can make the cooled coolant flow evenly into each battery pack 300 to cool and exchange heat with the heat in each battery pack 300, thus ensuring the heat dissipation effect of each battery pack 300.
