Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
As shown in Figure 1, the present invention provides a kind of relay-type thermal cell, including multiple battery piles 1, within each battery pile 1
It is embedded with activation device 2, all battery piles 1 are successively connected in parallel by connecting wire.
Using technical solution of the present invention, which when in use, is successively activated to multiple battery pile timesharing,
Make thermal cell that there is continual and steady output, the continuous working period and durability of thermal cell greatly promote, and slow down battery
Influence of the heap materials pyrolysis effect to thermal cell service life, greatly improves the utilization rate of battery pile material, in addition, this hair
It is bright to be preferably provided with thermal insulation layer between any two neighboring battery pile, so that each battery pile is compactly deployed in same
Within shell, realizing makes thermal cell lightweight on overall volume, and each battery pile respectively works independently, mutually not shadow
It rings.
Further, it is preferable to which relay-type thermal cell further includes shell 3, all battery piles 1 are mounted within shell 3, outside
3 surface of shell is provided with multiple poles 4.Insulating layer 5, the equal insulation layer 5 of all battery piles 1 are additionally provided in 3 inner wall surface of shell
Package.
In addition, relay-type thermal cell further includes thermal insulation layer 6, in multiple battery piles 1, two battery piles 1 of arbitrary neighborhood by every
Thermosphere 6 separates.6 thickness of thermal insulation layer is not less than 15mm.
Further, diode is also connected on connecting wire.Using the one-way conduction characteristic of diode, make each electricity
Pond piles up timesharing when successively activating, and output electric current is not in adverse current, ensure that relay-type thermal cell provided by the invention can
