AI Technical Summary
Technical Problem
The existing battery pack cooling device cannot effectively absorb the expansion force of the single battery, affecting the safety performance and service life of the battery pack.
Method used
By setting the pair of support bodies between the side plates of the liquid-cooled plate, the minimum distance between the side plates is controlled to avoid excessive deformation of the side plates causing the runner to collapse.
Benefits of technology
It effectively avoids the collapse of the runner, ensures effective heat dissipation of the single battery by the liquid-cooled plate, and improves the safety performance and service life of the battery pack.

Abstract
The embodiment of the utility model discloses a battery pack and electric equipment, and the battery pack comprises a liquid cooling plate which comprises a first side plate and a second side plate, and the first side plate and the second side plate are used for enclosing a flow channel; the first side plate comprises a plurality of first side plate main bodies and a plurality of first diagonal bracing bodies; the first side plate bodies are distributed at intervals in the third direction and provided with first gaps, and every two adjacent first side plate bodies are connected through a first opposite supporting body. The first opposite supporting body comprises a first abutting part and first connecting parts arranged on the two sides of the first abutting part, the first abutting part is opposite to a first gap between the two adjacent first side plate bodies, and the first abutting part is used for abutting against the second side plate under the action of external pressure. Under the condition that the first side plate is extruded by the expansion force of the single battery to be close to the second side plate, the effect of controlling the minimum distance between the side plates is achieved, and the situation that the liquid cooling plate cannot effectively dissipate heat of the single battery due to the fact that a runner between the side plates is too small and even collapses is avoided.
