Description

Technical Field

[0001] This utility model relates to the field of heat dissipation device technology, specifically a heat dissipation device for energy storage batteries. Background Technology

[0002] With the development of power batteries and new energy vehicles, and with the booming development of the energy storage industry, especially the electrochemical energy storage industry led by lithium-ion batteries, energy storage batteries mainly refer to batteries used in solar power generation equipment, wind power generation equipment, and renewable energy storage. The energy storage performance and stability of energy storage batteries are affected by the temperature of the energy storage batteries themselves. In order to ensure that the energy storage batteries maintain a stable working state during operation, a heat dissipation device needs to be installed on the outside of the energy storage batteries.

[0003] Most existing ventilation-type heat dissipation structures use heat dissipation fins in contact with the battery surface and a fan to drive airflow to dissipate heat. This heat dissipation method is relatively simple and the heat dissipation effect is not good. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation device for energy storage batteries, in order to solve the problem that most existing ventilation-type heat dissipation structures mentioned in the background art use heat dissipation fins in contact with the battery surface and a fan to drive airflow to achieve heat dissipation. This heat dissipation method is relatively simple and the heat dissipation effect is not good.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat dissipation device for energy storage batteries, comprising a battery box, a water-cooling component, and a heat dissipation component;

[0006] Wherein: the top of the battery box is connected to a box cover, and the box cover is connected to the four sides by fixing bolts, and the box cover is fixedly connected to the battery box by fixing bolts;

[0007] The water-cooling assembly includes a water-cooling plate installed on the inner wall of the battery box. The water-cooling plate has an S-shaped water channel inside. One end of the water channel is connected to a water inlet connector, and the other end of the water channel is connected to a water outlet connector. A contact plate is connected to the top of the water-cooling plate, and a heat-conducting plate is connected to the bottom of the contact plate. The heat-conducting plate extends into the interior of the water channel.

[0008] The heat dissipation assembly includes several partitions mounted on the surface of the contact plate. Heat dissipation fins are connected to the middle of the partitions. Ventilation holes are provided on both sides of the battery box. A cooling fan is fixedly installed inside the ventilation hole. The cooling fan is arranged correspondingly to the heat dissipation fins.

[0009] As a preferred embodiment of this utility model: a filter screen is fixedly installed on the surface of the cooling fan, and a protective screen is installed on the surface of the ventilation hole on the other side.

[0010] As a preferred embodiment of this utility model: a placement cavity is formed between several partitions, and limit clamps are symmetrically installed on both sides of the surface of the partitions.

[0011] As a preferred embodiment of this utility model, a temperature sensor is also installed on the top of the partition.

[0012] As a preferred embodiment of this utility model, mounting bases are installed around the bottom of the battery box.

[0013] As a preferred embodiment of this utility model: a charging interface is installed on the surface of the battery box, and a waterproof sealing cover is hinged to the top of the charging interface.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) A water-cooled plate is installed on the inner wall of the battery box. The water-cooled plate has an S-shaped water channel. When the battery is charging and discharging, the temperature gradually rises. At this time, cooling water is delivered to the water channel through the water inlet connector. When the cold water flows through the water channel, it carries away the heat conducted by the contact plate. The bottom of the contact plate is connected to a heat-conducting plate that extends into the water channel to increase the heat conduction area and accelerate heat dissipation. The water finally flows to the outside through the water outlet connector at the other end of the water channel. The water circulation facilitates the heat dissipation, improves the heat dissipation efficiency of the battery box, and avoids high-temperature load on the battery.

[0016] (2) Through the provided heat dissipation components, several partitions are installed on the surface of the contact plate, and heat dissipation fins are connected in the middle of the partitions. Ventilation holes are opened through both sides of the battery box. After the cooling fan rotates, it drives the external airflow into the battery box. At the same time, the airflow flows through the inside of the heat dissipation fins, so that the heat of the partitions in contact with the battery is transferred to the heat dissipation fins, which facilitates faster heat dissipation. The airflow is discharged through the ventilation hole on the other side. The filter installed on the surface of the cooling fan can filter the dust content in the air. At the same time, the protective net installed on the surface of the ventilation hole can prevent flying insects from entering the battery box and reduce the possibility of accidental short circuit.
