Abstract
Aspects of the present disclosure generally relate to a new class of heat transfer compositions. The heat transfer compositions include an HR-PIB. Heat transfer compositions described herein may further include an additional base fluid, an optional additive, or a combination thereof. Aspects described herein also generally relate to processes for producing the heat transfer compositions and to uses of the heat transfer compositions in, for example, immersion cooling applications. Aspects of the present disclosure also generally relate to heat management systems that include one or more heat-generating articles and a heat transfer composition that includes HR-PIB.
Claims20
A heat transfer composition, comprising:
- a base fluid comprising:
- highly reactive polyisobutylene (HR-PIB), the HR-PIB comprising:
- a first portion comprising polymer chains having alpha vinylidene groups;
- a second portion comprising polymer chains having beta vinylidene groups;
- a third portion comprising polymer chains having internal vinylidene groups, the internal vinylidene groups different from the beta vinylidene groups;
- an amount of the first portion that is in a range from greater than 75 wt % to 100 wt % based on a total wt % of the first portion, the second portion, and the third portion of the HR-PIB, the total wt % of the first portion, the second portion, and the third portion of the HR-PIB is equal to 100 wt %;
- and
- an amount of the second portion plus the third portion that is in a range from 0 wt % to less than 25 wt % based on the total wt % of the first portion, the second portion, and the third portion of the HR-PIB;
- and
- the heat transfer composition further comprises one or more of:
- a thermally conductive material comprising a carbon-based material, a metal-containing material, or a combination thereof;
- or
- a phase transition additive comprising an encapsulated paraffin wax, a metallic phase change material, an organic phase change material, or combinations thereof.
