Heat absorbing temperature control devices that include hydroxide
First Claim
1. An article of manufacture for heat absorption, comprising:
- (a) a flight data recorder that includes electronics that are sensitive to heat;
(b) hydroxide having a formula of Mx(OH)y, wherein “
M”
is selected from the group consisting of lithium, sodium, potassium, magnesium, calcium, beryllium, aluminum and ammonium, and wherein “
x” and
“
y”
are integers, said hydroxide being provided in an amount sufficient to effect a level of heat absorption so as to protect the electronics within the flight data recorder from damage based upon exposure to a predetermined level of heat exposure;
(c) support means for supporting said hydroxide, said hydroxide being supportable in relation to the flight data recorder by said support means;
wherein said hydroxide effects said level of heat absorption at least in part based on an irreversible decomposition of said hydroxide; and
wherein irreversible decomposition of the hydroxide forms a thermal insulation oxide layer around the flight data recorder.

Abstract
The increase of temperature of heat sensitive devices during heat generating conditions is prevented through the absorption of heat, by providing a hydroxide, such as Lithium Hydroxide, Sodium Hydroxide, Potassium Hydroxide, Magnesium Hydroxide, Calcium Hydroxide, Beryllium Hydroxide, Aluminum Hydroxide, Ammonium Hydroxide and mixtures thereof, in an amount sufficient to effect the required heat absorption. Where the heat generating conditions are generated by a heat generator, separate and distinct from the heat sensitive device, the hydroxide may be supported in a position between the heat sensitive device and the heat generator. Where the heat sensitive device is itself the heat generator, the hydroxide is in contact with the heat sensitive device, either directly or indirectly.
