Combined battery temperature control device

Abstract

The invention belongs to the technical field of battery energy and temperature control, and relates to a combined battery temperature control device. Battery heat transfer sheets are produced at front and rear sides of each single battery; heat exchange blind windows are formed at the left and right sides of each single battery; a heat exchange fluid inlet is arranged at the outer side of each heat exchange blind window; a combined battery upper cover board is formed around the outer side of the single battery; a single battery cover is formed at the top side of each single battery; a gap between each single battery cover and the combined battery upper cover board forms a fluid delivery pipe; and the heat exchange blind windows, the battery heat transfer sheets, the combined battery upper cover boards and the single battery covers are added to the single batteries to respectively form the single batteries with heat conducting sheets, and the single batteries with the heat conducting sheets are combined and assembled in series into the combined battery. The combined battery temperature control device is simple in main body structure, flexible in combination mode, safe and reliable in combination principle, and simple to use and operate, and can be used for serial and parallel combination of various rechargeable batteries.

Description

Technical field: [0001] The invention belongs to the technical field of battery energy and temperature control, and relates to a battery temperature balance and thermal management system device, in particular to a combined battery temperature control device. Background technique: [0002] At present, the battery thermal management system mainly considers the problem of heat source, and takes electric heating, heat pipe, wind (heat) cooling, liquid (heat) cooling, and heat regulation in the form of heat transfer medium as the main research objects, and does not consider how to improve the battery performance at all. Heat exchange performance and how to ensure the thermal balance of its battery. Because the surrounding space of the batteries is different after the batteries are grouped, such as the gap between the batteries is small, and the top and both sides are completely open, the flow of the general fluid is limited by the size of the flow channel, and a flow dead zone is...
