Problems solved by technology

[0007] In order to overcome the deficiencies of the prior art, the present invention provides a new thermal battery internal temperature control structure, which adopts a progressive heat absorption method to disperse heat and balance the internal temperature of the battery without causing excessive heat absorption. The temperature drops instantly, and the battery cannot supply power normally. At the same time, it also expands the range of the heating source inside the battery.

Abstract

The application discloses a novel thermal battery interior temperature control structure, which is mainly used for improving the safety performance of a thermal battery in high temperature working environment. The novel thermal battery interior temperature control structure includes a temperature control body, wherein the temperature control body is arranged inside the thermal battery, and includes a sandwich body; the sandwich body includes thermal insulation layers and heat absorption layers; the thermal insulation layers and the heat absorption layers are alternately arranged from top to bottom; the multiple thermal insulation layers are arranged outside the heat absorption layers; the thermal insulation layers are solid or thorough-hole circular plates in appearance, and the heat absorption layers are also solid or thorough-hole circular plates in appearance. The novel thermal battery interior temperature control structure is high in strength, can evenly dissipate interior heat ofthe thermal battery and balance the interior working temperature, thereby greatly improving the safety performance of the thermal battery.

Description

technical field [0001] The invention belongs to the technical field of thermal batteries, and in particular relates to an internal temperature control structure of thermal batteries. Background technique [0002] Thermal battery, also known as heat-activated battery, mainly uses molten salt as electrolyte, and relies on electrical activation or mechanical activation to ignite the internal pyrotechnic source. After activation, the battery heating system will make the solid molten salt reach the working temperature (that is, the electrolyte crystal changes from solid state to It is a kind of battery in which the positive and negative electrodes generate working current and voltage through electrolyte reaction. [0003] Thermal batteries have their own inherent advantages: high reliability, strong environmental adaptability, and long storage time. They can work in harsh environments such as high spin speed (for example, 16000 rpm) and high temperature (>450°C), low temperat...
