Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of energy storage, in particular to a constant temperature energy storage cabinet. Background Art
[0002] The battery is the core component of the energy storage battery cabinet, and the heat dissipation performance of the battery module is an important factor affecting the battery's working performance, working efficiency, service life and safety. At present, for the battery cabinets on the existing market, the battery cells are often placed directly on each layer of the bracket inside the cabinet. The equipment or components in the energy storage cabinet generate a lot of heat during operation. The closed cabinet cannot completely rely on the natural heat convection of the air to dissipate heat, which causes the ambient temperature of the equipment to continue to rise, and it cannot operate for a long time and even causes safety hazards. Moreover, when the outside temperature is too low, the low ambient temperature will cause the energy storage equipment to fail to operate, unable to charge and discharge, or the charging and discharging efficiency will be greatly reduced. If the battery works and charges and discharges in a low temperature environment for a long time, metallic lithium will precipitate on the surface of the battery anode. This process is irreversible and will cause long-term damage to the battery capacity. Utility Model Content
[0003] In view of the above problems, the utility model proposes a constant temperature energy storage cabinet, which increases the ambient temperature of the battery operation through heat convection of air, thereby ensuring that the battery operates at a suitable temperature.
[0004] The technical solution adopted by the utility model is as follows: a constant temperature energy storage cabinet, comprising a cabinet body, at least one battery cabinet is arranged in the cabinet body, an air conditioner is arranged on the outer wall of the cabinet body, a cavity is arranged between the rear wall of the battery cabinet and the rear wall of the cabinet body, a first vent is arranged on the rear wall of the battery cabinet, a second vent is arranged on the front wall of the battery cabinet, an air outlet of the air conditioner is connected to the first vent, and an air inlet of the air conditioner is connected to the second vent.
[0005] Optionally, an air guide plate is installed on the rear wall of the battery cabinet, and the air guide plate faces the air outlet of the air conditioner.
[0006] Optionally, a third ventilation hole is provided on the side wall of the battery cabinet, and the third ventilation hole is connected to the first ventilation hole.
[0007] Optionally, the battery cabinet is provided with a first fan for creating a negative pressure environment inside the battery cabinet.

[0011] Optionally, a third fan is provided inside the middle layer for forming a negative pressure environment inside the middle layer.
[0012] The beneficial effect of the utility model is that multiple battery packs are arranged in the battery cabinet. When the ambient temperature in the battery pack is too high, the air conditioning refrigeration system is turned on, and the cold air blown by the air conditioning refrigeration enters the battery cabinet through the air outlet and the first vent, and the heat is quickly taken away by the thermal convection of the air. The hot air after passing through the battery pack returns to the air conditioner through the second vent and the air inlet of the air conditioner to realize internal circulation.

DETAILED DESCRIPTION
[0016] The utility model is described in detail below in conjunction with the accompanying drawings.
[0017] like Figure 1 and 2As shown, this embodiment discloses a constant temperature energy storage cabinet, including a cabinet body 1, wherein at least one battery cabinet 2 is arranged in the cabinet body 1, an air conditioner 3 is arranged on the outer wall of the cabinet body 1, a cavity is arranged between the rear wall of the battery cabinet 2 and the rear wall of the cabinet body 1, a first vent 21 is arranged on the rear wall of the battery cabinet 2, a second vent is arranged on the front wall of the battery cabinet 2, an air outlet 31 of the air conditioner 3 is connected to the first vent 21, and an air inlet 32 of the air conditioner 3 is connected to the second vent. A plurality of battery packs 7 are arranged in the battery cabinet 2. When the ambient temperature in the battery pack 7 is too high, the refrigeration system of the air conditioner 3 is turned on, and the cold air blown out by the air conditioner 3 enters the battery cabinet 2 through the air outlet 31 and the first vent 21, and the heat is quickly taken away by the thermal convection of the air. The hot air after passing through the battery pack 7 returns to the air conditioner 3 through the second vent and the air inlet 32 of the air conditioner 3 to realize internal circulation. Similarly, when the ambient temperature in the battery pack 7 is too low, the heating function of the air conditioner 3 is turned on, and the hot air blown out by the air conditioner 3 enters the battery cabinet 2 through the air outlet 31 and the first vent 21, and the ambient temperature of the battery operation is increased by air convection, thereby ensuring that the battery operates at a suitable temperature.
[0018] In this embodiment, if Figure 1 and 2 As shown, the rear wall of the battery cabinet 2 is provided with an air guide plate 4, which faces the air outlet 31 of the air conditioner 3. The gas is discharged from the air outlet 31 of the air conditioner 3, and after the air blown out hits the guide plate, the air spreads upward, downward, leftward, rightward and around, and enters the battery cabinet 2 through the first vent 21.
[0019] In this embodiment, if Figure 1 and 2 As shown, the side wall of the battery cabinet 2 is provided with a third vent 22, and the third vent 22 is connected to the first vent 21. There can be multiple third vents 22, which increases the efficiency of heat exchange between the gas inside the battery cabinet 2 and the air outlet gas of the air conditioner 3.
[0020] In this embodiment, the battery cabinet 2 is provided with a first fan for forming a negative pressure environment inside the battery cabinet 2. The first fan continuously discharges the gas inside the battery cabinet 2 from the second vent, and the battery cabinet 2 is under negative pressure, so that the gas is quickly sucked into the battery cabinet 2, ensuring that the battery cabinet 2 is at a suitable temperature.
[0021] In this embodiment, the cabinet 1 is provided with a second fan for forming a negative pressure environment at the air inlet 32 of the air conditioner 3, forcing the gas from the second vent to enter the air conditioner 3, forming a circulation.
[0022] In this embodiment, a sheet metal part for windproofing is provided in the battery cabinet 2, and the outer wall of the sheet metal part is covered with thermal insulation cotton. The sheet metal part and the battery pack 7 located in the battery cabinet 2 isolate the rear wall and the front wall of the battery cabinet 2, and the thermal insulation cotton prevents the water droplets formed by condensation or dew from the outside wind contacting the relatively cold sheet metal part and affecting the battery pack 7 below.
[0023] In this embodiment, if Figure 2 As shown, the cabinet 1 is further provided with an intermediate layer 5 for installing the control box 8, the rear wall of the cabinet 1 is provided with a fourth vent 11 communicating with the intermediate layer 5, and the front wall of the cabinet 1 is provided with a fifth vent 12 communicating with the intermediate layer 5. When there are two battery cabinets 2, the intermediate layer 5 is arranged between two adjacent battery cabinets 2, and the intermediate layer 5 separates the two battery cabinets 2 to prevent the temperatures of the two adjacent battery cabinets 2 from affecting each other.
[0024] In this embodiment, a third fan is provided inside the middle layer 5 for forming a negative pressure environment inside the middle layer 5. The third fan helps to accelerate the air flow. The middle layer 5 separates the two battery cabinets 2 through a partition 6.
