Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation in a battery room, in particular to an air-cooled heat dissipation device for an energy storage battery cluster in a battery room. Background Art

[0002] Battery room energy storage battery cluster refers to an energy storage system consisting of a group of battery cells or batteries stored in a battery room. These battery cells or battery packs are usually combined together to provide a larger capacity of energy storage capacity. Battery clusters are usually composed of multiple battery cells connected in series or in parallel to meet specific energy storage needs. In the battery room, battery clusters can be used to store electrical energy and applied in different fields such as industry, commerce, and residence as backup power or energy storage systems. By combining battery cells or battery packs into battery clusters, higher energy storage capacity and output power can be achieved to meet larger-scale energy needs. Battery room energy storage battery clusters usually need to be equipped with a battery management system (BMS) to monitor and manage the battery charging and discharging process to ensure the safety and stable operation of the battery. In addition, the battery cluster may also need to be equipped with an inverter or other power electronic equipment to convert the stored electrical energy into usable AC or DC power, so the energy storage battery cluster will emit heat during operation and needs to be cooled.

[0003] After searching, the Chinese patent publication number CN216597745U discloses a ventilation device for the battery room of a substation, including an auxiliary ventilation structure installed between the right side wall of the battery room body and the bottom of the load-bearing plate, through holes are opened on the upper and lower sides of the right side wall of the battery room body, an exhaust fan is fixedly installed in the upper through hole, and an induced draft fan is fixedly installed in the lower through hole, and a wind-guided support structure is fixedly installed between the bottom surface of the inner cavity of the battery room body and the bottom surface of the load-bearing plate.

[0004] In the above scheme, exhaust holes are opened on the load-bearing plate at the bottom of the battery room, and cold air is poured into the space below the load-bearing plate through the induced draft fan. After the cold air passes through the exhaust holes, the battery modules placed on the load-bearing plate are ventilated and cooled. The battery modules are generally stacked in multiple layers. The battery modules on the bottom layer placed on the load-bearing plate are closer to the exhaust holes and can be well cooled. However, the battery modules on the upper layer are far away from the exhaust holes. After the cold air exchanges heat with the battery modules on the bottom layer, the temperature gradually rises. When it reaches the battery modules on the upper layer, the air has already carried a lot of heat and has become hot air. Therefore, the cooling and heat dissipation effect on the battery modules on the upper layer is not ideal. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that after heat exchange, the bottom battery module will transfer hot air to the surrounding of the upper battery module, resulting in unsatisfactory heat dissipation effect of the upper module, and proposes a battery room energy storage battery cluster air cooling and heat dissipation device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A wind-cooled heat dissipation device for an energy storage battery cluster in a battery room, comprising a battery box, and also comprising: a main induced draft fan fixedly connected to the battery box, wherein a heat sink is fixedly connected inside the battery box, a cavity is formed between the bottom of the heat sink and the battery box, and an air outlet end of the main induced draft fan is connected to the cavity; an auxiliary induced draft fan fixedly connected to the battery box, and an air outlet end of the auxiliary induced draft fan is connected to the battery box.

[0008] In order to facilitate the delivery of cold air into the cavity, preferably, a shunt box is fixedly connected to the inner wall of the battery box, and the shunt box is connected to the cavity through a shunt pipe.

[0009] In order to improve the heat dissipation effect of the battery, preferably, the heat dissipation plate is fixedly connected in the battery box through a connecting plate, and the connecting plate divides the cavity to form a shunt channel.

[0010] In order to facilitate the discharge of hot air in the shunt duct, preferably, a main air outlet is provided on the battery box, and the main air outlet is connected to the shunt channel.

[0011] In order to facilitate the timely discharge of hot air in the battery box, preferably, an auxiliary air outlet is provided on the battery box, and the auxiliary air outlet is connected to the battery box.

[0012] In order to facilitate the placement of the batteries, preferably, at least two groups of partition plates are fixedly connected to the top of the heat sink, and placement grooves are formed between the partition plates.

[0013] Compared with the prior art, the utility model provides a battery room energy storage battery cluster air cooling and heat dissipation device, which has the following beneficial effects:

[0014] 1. The battery room energy storage battery cluster air cooling device can dissipate the heat generated above and below the battery in time through the use of auxiliary induced draft fans and main induced draft fans. After the heat exchange, the bottom battery will not transfer hot air to the surrounding of the upper battery, so the heat around the battery can be dissipated in time, which can effectively prevent the battery from overheating and ensure the safety performance of the battery.

[0015] 2. The air-cooling heat dissipation device for the energy storage battery cluster in the battery room timely transports the heat generated in the shunt channel to help the battery dissipate heat and reduce the temperature of the battery. The circulating air is directly discharged to the outside to ensure smooth gas flow. At the same time, the cold air can directly dissipate heat for the battery, reduce the impact of subsequent heat on the upper battery, and improve the cooling effect on the battery.

[0016] 3. The battery room energy storage battery cluster air-cooling heat dissipation device can effectively transfer the heat generated by the battery to the external environment through the heat dissipation plate, and is relatively light and suitable for heat dissipation in the battery box.

[0017] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The auxiliary induced draft fan and the main induced draft fan in the utility model are used in combination to dissipate the heat generated above and below the battery in time, and the batteries on the bottom layer will not transmit hot air to the surroundings of the upper batteries after heat exchange, so that the heat around the batteries can be dissipated in time, which can effectively prevent the battery from overheating and ensure the safety performance of the battery.

The heat sink 3 made of aluminum alloy can effectively conduct the heat generated by the battery to the external environment, and is relatively light and suitable for heat dissipation in the battery box 1. Copper is another commonly used material with excellent thermal conductivity and can quickly conduct heat to the surface of the heat sink 3.

The main induced draft fan 2 is also fixedly connected to the battery box 1, which draws external air into the battery box 1 to help dissipate heat and maintain a suitable working temperature. When the energy storage battery in the battery box 1 is working, it will generate heat, and excessively high temperature may affect the performance and life of the battery.

A main air outlet 101 is provided on the opposite side of the main induced draft fan 2, and the main air outlet 101 is connected to the shunt channel. When the main induced draft fan 2 is started, the external cold air can be introduced into the shunt box 201, and then the air will be affected by the shunt pipe 202, and the cold air will be transported to the cavity, and the cavity is affected by the connecting plate 302 and divided into shunt channels, and the cold air can dissipate heat through the shunt channels.

[0029] The principle here is, please refer to Figure 4As shown in the figure, the energy storage battery in the battery box 1 will generate heat when working, and the heat will be dispersed and dissipated through the connecting plate 302, and the main air outlet 101 is arranged on the opposite side of the main induced draft fan 2.

The circulating air is directly discharged to the outside, which ensures the smooth flow of gas while allowing the cold air to directly dissipate the heat of the battery, reducing the impact of subsequent heat on the upper battery and improving the cooling effect on the battery.

[0030] In addition, at least two groups of partition plates 301 are fixedly connected to the top of the heat sink 3, and placement grooves are formed between the partition plates 301.

An auxiliary induced draft fan 4 is also fixedly connected to the battery box 1, and an auxiliary air outlet 102 is also provided on the battery box 1, which is arranged on the opposite side of the auxiliary induced draft fan 4. By starting the auxiliary induced draft fan 4, the heat dissipation of the battery can be effectively helped, and the heat generated by the battery can be quickly transferred to the external environment to ensure that the operating temperature of the battery is always within an appropriate range, which helps to maintain the stable performance of the battery and extend the service life of the battery. The auxiliary induced draft fan 4 and the main induced draft fan 2 are used in combination to dissipate the heat generated above and below the battery in time, and the batteries on the bottom layer will not transmit hot air to the surroundings of the upper batteries after heat exchange, so that the heat around the batteries can be dissipated in time, which can effectively prevent the battery from overheating and ensure the safety performance of the battery.
