Problems solved by technology

[0003] 1. When using the heat dissipation fins of the box or the overall heat dissipation of the box, the heat dissipation fins of the box will be large in size, low in energy density, and poor in heat dissipation;
[0004] 2. At the same time, if the battery box is cooled by liquid, it needs to be equipped with a coolant circulation system, which increases the heat dissipation components, reduces the efficiency of the vehicle, and requires a high space for the vehicle;
[0005] 3. Both of the above two methods independently dissipate heat for different internal modules, which cannot achieve the effect of balanced temperature among modules

Abstract

The invention provides a battery box, a battery heat dissipation system and an electric car, relating to the technical field of battery heat dissipation. The battery box comprises a box body and a phase change heat pipe group, the box body is internally provided with multiple electric core heating assemblies, the phase change heat pipe group is fixedly arranged on a surface of an inner side of thebox body and connected with the multiple electric core heating assemblies respectively, an outer side surface, which is opposite to the phase change heat pipe group, of the box body is provided witha condensing area, a heat dissipation structure is arranged at the condensing area and used for dissipating heat from the condensing area. By utilizing the high heat-conducting property of the phase change heat pipe group, heat generated by various electric core heating assemblies can be rapidly conducted, temperatures among various modules are balanced, the condensing area is arranged outside thebox body, the heat is dissipated by the heat dissipation structure, the purpose of rapid heat dissipation is achieved, and a heat dissipation system is not needed, so that the size of the battery boxis reduced to an extremely great extent.

Description

technical field [0001] The invention relates to the technical field of battery cooling, in particular to a battery box, a battery cooling system and an electric vehicle. Background technique [0002] As a key component, the electric bus battery box is the source of vehicle power and plays a very important role. The heat dissipation problem of the battery box has always been a problem that is difficult to solve in the industry. At present, the main heat dissipation method in the industry is to use aluminum box or sheet metal box to dissipate heat, or coolant to dissipate heat. There are some problems in the above heat dissipation methods: [0003] 1. When using the heat dissipation fins of the box or the overall heat dissipation of the box, the heat dissipation fins of the box will be large in size, low in energy density, and poor in heat dissipation; [0004] 2. At the same time, if the battery box is cooled by liquid, it needs to be equipped with a coolant circulation sys...
