Description

Technical Field

[0001] The utility model relates to the technical field of thermal batteries, and more specifically to a heat dissipation shell for thermal battery packaging. Background Art

[0002] Thermal battery. Also known as heat-activated reserve battery. The electrolyte is a non-conductive solid when stored. When in use, the heating agent inside is ignited by an electric ignition head or a striker mechanism, causing the electrolyte to melt and become an ion conductor, thus being activated.

[0003] At present, in order to ensure the stable excitation of thermal batteries and ensure that the fixed electrolyte inside is activated as an ion conductor, the interior of the thermal battery usually contains a sufficient amount of heating agent. After the heating agent is ignited by an electric ignition head or a striker mechanism, excessive heat is usually generated, causing the thermal battery to operate in a high-temperature environment after being activated, affecting the stability of the thermal battery. In view of this, we propose a heat dissipation shell for thermal battery packaging. Utility Model Content

The outer edge surface of the heat dissipation shell is provided with an arc-shaped groove body corresponding to the position of the heat dissipation component for increasing the surface area to improve the heat dissipation effect.

At the same time, the X-shaped structure is beneficial to enhance the bearing effect between the outer shell and the heat dissipation shell, thereby solving the problem that excessive heat is usually generated after the heating agent is ignited by the electric ignition head or the firing pin mechanism, causing the thermal battery to operate in a high-temperature environment after being activated, thereby affecting the stability of the thermal battery.

[0009] Preferably, a heat collecting cavity for collecting heat is formed between the ends of the symmetrically arranged arc-shaped heat dissipating fins facing the outer shell.

[0010] Preferably, a heat conducting plate is formed at one end of the arc-shaped heat dissipating fin away from the outer shell, and an arc-shaped heat conducting support sheet for improving the compressive strength between the outer shell and the heat dissipating housing is constructed on the outer edge surface of the end of the heat conducting plate away from the outer shell.

[0011] Preferably, a load-bearing portion for enhancing the structural strength of the heat dissipation housing is formed on the outer edge surface of the heat dissipation housing between the arc-surface grooves, and a pressure-bearing structure is arranged in an annular array on the inner edge surface of the heat dissipation housing.

[0012] Preferably, the pressure-bearing structure includes symmetrically arranged V-shaped support parts, a columnar thickened part is arranged between one end of the support part and the inner edge surface of the heat dissipation shell, and one end of the support part away from the columnar thickened part is connected to the outer edge surface of the outer shell.

[0013] Preferably, an inner core is fixedly disposed inside the sealed shell, and an electrode 1 and an electrode 2 are respectively sealed and fixedly disposed at two ends of the inner core.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model designs the structure of the heat dissipation component, which can absorb the heat generated inside the sealed shell and transmit it to the outside, and designs the arc-shaped heat dissipation fins to be symmetrically cross-arranged in an X shape, so that the surface area is increased through the X-shaped structure to enhance the effect of absorbing and transmitting heat. At the same time, the X-shaped structure is beneficial to enhance the bearing effect between the outer shell and the heat dissipation shell, thereby solving the problem that excessive heat is usually generated after the heating agent is ignited by the electric ignition head or the striker mechanism, causing the thermal battery to operate in a high-temperature environment after being activated, thereby affecting the stability of the thermal battery.

The utility model also forms a heat-gathering cavity between the symmetrically arranged arc-shaped heat dissipating fins toward one end of the outer shell, which is conducive to gathering heat and achieving the effect of gathering and diffusing heat. It further solves the problem that after the heating agent is ignited by the electric ignition head or the striker mechanism, excessive heat is usually generated, causing the thermal battery to operate in a high-temperature environment after being activated, thereby affecting the stability of the thermal battery.
