Abstract: A cooling device is provided. The cooling device includes a first and second cooling members each including a first side and a second side oppositely disposed. The first cooling member is provided with a first flow channel, and the second cooling member is provided with a second flow channel. The first side of the first cooling member is fixedly connected to the second side of the second cooling member. The first side of the first cooling member is provided with a first gap. The second side of the second cooling member is provided with a second gap. The first flow channel communicates with the second flow channel through the first gap and the second gap.

Abstract: A battery box and a battery pack are provided. The battery box includes: a bottom plate; a side plate, where the side plate surrounds a peripheral edge of the bottom plate and is combined with the bottom plate to form an accommodating cavity for accommodating a battery module; and a plurality of protrusions disposed in the accommodating cavity and disposed on the bottom plate, where the protrusions are protruded from the bottom plate in a first direction and arranged in an array in a second direction and a third direction, a top portion of each of the protrusions is configured to contact a bottom portion of the battery module to lift the battery module.

Abstract: A liquid cooling plate, a battery pack and a lower case therefor, and an energy storage system are provided. A plurality of main liquid cooling flow channels and auxiliary liquid cooling flow channels are arranged in a liquid cooling plate of a lower case for a battery pack. An integrated design of the liquid cooling plate and the lower case for the battery pack is realized without the need for installing a separate liquid cooling plate, so that the space utilization rate and energy density of the battery pack is improved. Moreover, the auxiliary liquid cooling flow channels cooperates with the main liquid cooling flow channels, the heat exchange effect between the coolant and the battery cell is improved, and the temperature consistency among the battery cells is enhanced. Therefore, the technical problem of poor temperature consistency among the battery cells is alleviated.

Abstract: The invention relates to a coating composition comprising: (a) 10% to 99.9% by weight of resin based on the total weight of the coating composition; and (b) 0.1% to 20% by weight of a formaldehyde scavenger based on the total weight of the coating composition, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature. The invention relates to use of a coating composition for removing free formaldehyde from the environment, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature.
