Cooling system for downhole tools
First Claim
1. Apparatus for cooling a component inside a tool, comprising:
- a heat sink positioned next to the component; and
an insulation layer surrounding the component to reduce heat transfer to the component, wherein the insulating layer includes a container that stores a vacuum layer, wherein the container includes a dewar flask.

Abstract
Apparatus and method for cooling a component inside a tool includes a container and a plurality of heat sinks positioned in the container. The components are positioned in the container with the heat sinks for maintaining a reduced temperature inside the container. Further, an insulating layer and a reflective layer surround the heat sinks and components to reduce heat transfer. Alternatively, the container can have a hollow wall that encloses the space in which a heat sink material (such as an eutectic material) is disposed. The components to be protected are located in the container. The eutectic material includes a composition having tin and zinc. The insulating layer includes a container that stores a vacuum layer, such as a dewar flask.
