PROTECTIVE SLEEVE, BATTERY THERMAL MANAGEMENT SYSTEM, AND BATTERY
A protective sleeve, a battery thermal management system, and a battery are provided. The protective sleeve is configured to sleeve a pipeline and includes a sleeve body, where the sleeve body includes a first bundling section, a first diameter-variable section, a protective section, a second diameter-variable section, and a second bundling section arranged in sequence. Diameters of the first bundling section and the second bundling section are smaller than diameter of the protective section, and the first bundling section and the second bundling section are capable of elastically clamping the pipeline, so as to fix the protective sleeve to the pipeline. This can improve the convenience of installing and removing the protective sleeve on the pipeline.
1 . A protective sleeve, configured to sleeve a pipeline, wherein the protective sleeve comprises a sleeve body, wherein the sleeve body comprises a first bundling section, a first diameter-variable section, a protective section, a second diameter-variable section, and a second bundling section arranged in sequence, wherein
diameters of the first bundling section and the second bundling section are smaller than diameter of the protective section, and the first bundling section and the second bundling section are capable of elastically clamping the pipeline, so as to fix the protective sleeve to the pipeline.
2 . The protective sleeve according to claim 1 , wherein the sleeve body is woven from fiber.
3 . The protective sleeve according to claim 1 , wherein the first bundling section and the second bundling section are woven from elastic fiber.
4 . The protective sleeve according to claim 1 , wherein the protective section is woven from inorganic fiber.
5 . The protective sleeve according to claim 1 , wherein the first diameter-variable section and the second diameter-variable section are woven from a mixture of elastic fiber and inorganic fiber.
6 . The protective sleeve according to claim 5 , wherein
the elastic fiber comprises at least one of polyester fiber or nylon fiber; and/or
the inorganic fiber comprises at least one of glass fiber or ceramic fiber.
7 . The protective sleeve according to claim 1 , wherein the protective sleeve further comprises a mechanical performance enhancement layer, wherein the mechanical performance enhancement layer is disposed at least in the first diameter-variable section and the second diameter-variable section.
8 . The protective sleeve according to claim 7 , wherein the mechanical performance enhancement layer is further disposed in the first bundling section, the second bundling section, and the protective section.
9 . The protective sleeve according to claim 7 , wherein the protective sleeve comprises a plurality of mechanical performance enhancement layers, wherein the plurality of mechanical performance enhancement layers are located on an inner side and/or an outer side of the sleeve body.
10 . The protective sleeve according to claim 7 , wherein
the mechanical performance enhancement layer comprises at least one of rubber or resin; and/or
the mechanical performance enhancement layer is a coating layer.
11 . The protective sleeve according to claim 1 , wherein the protective sleeve is provided with a fire protection layer on an outer surface.
12 . The protective sleeve according to claim 11 , wherein the fire protection layer comprises at least one of fire-resistant mica and ceramicized silicone rubber.
13 . A battery thermal management system, comprising a coolant circulation loop and the protective sleeve according to claim 1 fixed to a pipeline of the coolant circulation loop.
14 . A battery, comprising the battery thermal management system according to claim 13 .
