Description

Technical Field

[0001] This utility model relates to the technical field of liquid-cooled valve equipment, and more specifically, to a drain valve and liquid-cooled energy storage equipment for a liquid-cooled energy storage system. Background Technology

[0002] A liquid-cooled energy storage system is a system that uses a liquid as a cooling medium to remove heat generated by equipment through circulation. In energy storage systems, the main function of a liquid-cooled system is to ensure the stable operation of core equipment such as batteries and improve energy utilization efficiency. Due to its superior heat dissipation, stability, reliability, and long service life, liquid-cooled energy storage systems have been widely used in the energy storage industry and are gradually becoming the mainstream cooling method. A typical liquid-cooled energy storage system consists of a coolant, liquid-cooled plates, a liquid-cooled pump, liquid-cooled piping, a condenser, and an evaporator. The liquid-cooled plates and accessories are an important component of the system, primarily responsible for supporting equipment such as batteries and ensuring good contact between them and the cooling liquid.

[0003] During the use of liquid-cooled energy storage systems, the coolant must be replaced regularly, the pipes cleaned, and the filters replaced to prevent blockage and corrosion and ensure the normal operation of the system.

[0004] However, in the existing technology, the discharge flow rate of the drain valve of the liquid cooling system is small and the discharge speed is slow. The excessively long discharge time of the energy storage cooling equipment will lead to increased costs and increased safety risks. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0027] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment provides a drain valve for a liquid-cooled energy storage system, including a multi-port connector 100 and a drain valve body 200; the multi-port connector 100 is provided with a connecting seat 110 for connecting to the drain valve body 200; a drain valve core 300 is provided inside the drain valve body 200, and a mounting seat 120 for mounting the drain valve core 300 is provided inside the connecting seat 110; a connecting rod 130 is provided between the mounting seat 120 and the side wall of the connecting seat 110; an elastic reset member 210 is provided between the drain valve core 300 and the mounting seat 120, and under the action of the elastic reset member 210, the drain valve core 300 can abut and seal with the drain valve body 200.

[0028] Specifically, when the coolant in the liquid-cooled energy storage system needs to be replaced, the operator inserts the male connector of the drain valve into the drain valve body 200. The plug inside the male connector can press against the drain valve core 300, and the drain valve core 300 presses against the elastic reset member 210, thereby separating the drain valve core 300 from the drain valve body 200, making the drain channel unobstructed, and allowing the coolant to be discharged smoothly.

[0029] The drain valve core 300 is disc-shaped, which can reduce the axial space occupied by the drain valve core 300 in the drain valve body 200, thereby providing a larger flow passage and increasing the drain flow rate when the drain valve core 300 is far away from the sealing ring 230 of the drain valve body 200.

[0030] In addition, a sealing groove is provided on the outer side of the drain valve core 300, and a first sealing ring 220 is installed in the sealing groove. A sealing retaining ring 230 is provided on the inner wall of the drain valve body 200. The first sealing ring 220 can abut against the sealing retaining ring 230. When the drain valve core 300 is pushed away from the sealing retaining ring 230 by the drain valve male connector, the space in the drain valve body 200 near the sealing retaining ring 230 can be quickly released, thereby increasing the space of the drain flow channel and increasing the drain flow rate.

[0031] It should be noted that the mounting base 120 is installed inside the multi-port connector 100 by multiple connecting rods 130. The connecting rods 130 are fixedly connected to the inner wall of the multi-port connector 100, and there is a flow channel for the cooling medium to pass through between the mounting base 120 and the inner wall of the multi-port connector 100.

[0032] It should be noted that the drain valve body 200 is laser-welded inside the connecting seat 110, and a second sealing ring 250 is provided between the drain valve body 200 and the connecting seat 110.

[0033] See Figures 1-6 As shown, in the optional solution of this embodiment, the elastic reset member 210 adopts a compression spring, one end of which is sleeved on the mounting base 120, and the other end abuts against the drain valve core 300.

[0034] One end of the drain valve core 300 is provided with a connecting groove 310 for installing the elastic reset member 210.

[0035] Specifically, one end of the elastic reset member 210 is fitted onto the mounting base 120, and the other end abuts against the connecting groove 310 of the drain valve core 300. The size of the connecting groove 310 is larger than the size of the mounting base 120.

[0036] See Figures 1-6 As shown, in the optional embodiment, the inner wall of the drain valve body 200 is provided with a plurality of guide rods 240, and the drain valve core 300 is provided with a guide groove 320 adapted to the guide rods 240.

[0037] Specifically, a guide groove 320 is provided on the drain valve core 300, and multiple guide rods 240 are provided on the inner wall of the drain valve body 200. The guide groove 320 on the drain valve core 300 cooperates with the guide rods 240 on the inner wall of the drain valve body 200, so that the drain valve core 300 can move stably.

[0038] See Figures 1-6 As shown, in an optional embodiment, the end of the drain valve core 300 away from the mounting base 120 is provided with a trigger rod 330 so that when the drain valve male connector is inserted into the drain valve body 200, the trigger rod 330 can be driven to press the elastic reset member 210.

[0039] Specifically, a trigger rod 330 is provided at the end of the drain valve core 300 away from the mounting base 120. When the male drain valve connector is inserted into the drain valve body 200, it can drive the trigger rod 330 to move, thereby driving the drain valve core 300 away from the sealing ring 230.

[0040] The multi-port connector 100 is provided with a cedar connector 140 for connecting to the main cooling pipeline 400 and a VDA connector 150 for connecting to the secondary pipeline 500.

[0041] The drain valve body 200 is fitted with a removable protective cover 160.

[0042] This embodiment provides a liquid-cooled energy storage device, including a drain valve for a liquid-cooled energy storage system.

[0043] Specifically, the liquid-cooled energy storage device provided in this embodiment has the advantages of the above-mentioned liquid-cooled energy storage system drain valve compared with the prior art, which will not be elaborated here.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
