Abstract

The invention discloses a cylindrical power battery module integrating heat radiating and heating, which comprises a battery cell lower support, a battery cell support cover, a plurality of cylindrical power battery cells and a heating device, wherein the battery cell lower support and the battery cell support cover are in snap-joint connection to form a box body; an inner part of the box body is an installation space of the cylindrical power battery cells. The cylindrical power battery module integrating heat radiating and heating is characterized in that a heat conduction pipe is arranged between each two adjacent rows or each two adjacent columns of cylindrical power battery cells; heat conduction silica gel is charged in a combination body formed by the battery cell lower support, each cylindrical power battery cell and the corresponding heat conduction pipe; a battery cell group tightly fits to each heat conduction pipe through the corresponding heat conduction silica gel; each heat conduction pipe is of an integral structure; heat radiating flakes are respectively connected to two ends of each heat conduction pipe; the heat conduction pipes and the heat radiating flakes form battery pack external and internal heat radiating structures; heating devices are arranged on the upper surface and the lower surface of the box body. The cylindrical power battery module integrating heat radiating and heating provided by the invention achieves a favorable heat radiating and heating effect.

Description

technical field [0001] The invention relates to the field of battery energy, in particular to a cylindrical power battery module integrating heat dissipation and heating. Background technique [0002] With the dwindling of resources, energy has been difficult to meet the needs of human beings. Energy storage (power battery) has entered people's lives with an advanced technology and plays a vital role in human survival. [0003] However, the power battery has a large working current and generates a lot of heat. At the same time, the battery pack is in a relatively closed environment, which will cause the temperature of the battery to rise. The working temperature of the battery material must not be higher than 60°C, but now the outdoor temperature may be close to 40°C, and the heat generated by the battery itself will cause the temperature of the battery's working environment to rise. If thermal runaway occurs, in order to avoid becoming "Grilling", it is especially importan...
