Embodiment Construction

[0035] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0036] In this disclosure, unless stated otherwise, the orientation words used such as "longitudinal, horizontal" are defined based on the power battery box, specifically, the length direction of the power battery box is the vertical direction, and the width direction is the horizontal direction , "Front and rear" are defined based on the flow of the heat exchange fluid, which defines that the heat exchange fluid flows from front to rear. In addition, the ordinal words "first", "second" and the like used in the present disclosure are for distinguishing one element from another element, and do not have sequence or importance. Furthermore, when the following d...

Abstract

The invention relates to a power cell casing and a power cell. The power cell casing is used for receiving a cell or a cell unit. The power cell casing is provided with a chamber structure for flowingof heat exchange liquid, wherein the chamber structure includes at least one water inlet channel and at least two water outlet channels extending in a longitudinal direction and multiple cooling water channels extending in a lateral direction, in the lateral direction, one water inlet channel is arranged between two adjacent water outlet channels, a set of heat exchange water channels is arrangedbetween the water inlet channel and the adjacent water outlet channel, each set of heat exchange water channels includes multiple heat exchange water channels, the multiple heat exchange water channels in the same set are in fluid communication in parallel between the water inlet channels and the adjacent water outlet channels, the casing includes a bottom plate used for fixing the cell or the cell unit, at least the water inlet channel and the heat exchange water channels are disposed on the bottom plate, and multiple turbulent structures spaced apart in the longitudinal direction are constructed in the water inlet channels. The power cell casing is advantaged in that the power cell casing can be both lightweight and with the heat exchange function for the single cell or the cell unit.

Description

technical field [0001] The present disclosure relates to the technical field of power batteries, and in particular, to a power battery case and a power battery. Background technique [0002] The development of electric vehicles is the current mainstream trend. Power batteries are the main power source of electric vehicles. The performance of power batteries directly determines the safety and service life of electric vehicles. The power battery includes an outer casing for accommodating the single battery or battery unit, and a cooling device for cooling the single battery or battery unit. During the use of the power battery, the single battery or battery unit will generate heat, and the cooling device can cool the single battery or battery unit to avoid excessive temperature affecting the performance of the battery cell or even causing danger. [0003] In the related technology, a liquid cooling plate is added between the outsourcing box and the single battery or battery un...
