Abstract
A sorption cooling apparatus for cooling a region in a downhole tool deployed on a wellbore conveyance device includes a container having an interior chamber in which a first region is formed, a liquid refrigerant residing in the interior chamber, a chamber located in a second region of the downhole tool, a compact desiccant body in the chamber, and a refrigerant passage between a first region containing the liquid refrigerant and the second region containing the compact desiccant body. The vapor generated during evaporation of the liquid refrigerant passes through the vapor passage to the compact desiccant in the second region.
Claims16
A sorption cooling apparatus for cooling a region in a downhole tool deployed on a wellbore conveyance device, comprising:
- a container having an interior chamber, the container being associated with the downhole tool;
- a refrigerant residing in the interior chamber;
- a chamber located in the downhole tool;
- a compact desiccant body in the chamber;
- and
- a refrigerant passage between the first region containing the refrigerant and the interior chamber containing the compact desiccant body, wherein vapor generated during evaporation of the refrigerant passes through the vapor passage to the compact desiccant.
A sorption cooling apparatus for cooling a region in a downhole tool deployed on a wellbore conveyance device, comprising:
- a container having an interior chamber, the container being associated with the downhole tool;
- a refrigerant residing in the interior chamber;
- a chamber located in the downhole tool;
- a consolidated, compact zeolite body in the chamber, the compact zeolite body being preformed into a shape complementary to the chamber, the compact zeolite body being formed of individual zeolite particles having substantially no interstitial space;
- and
- a refrigerant passage between the interior chamber containing the refrigerant and the compact desiccant body, wherein vapor generated during evaporation of the refrigerant passes through the vapor passage to the compact desiccant.
A method for cooling a region in a downhole tool deployed on a wellbore conveyance device, comprising:
- forming an interior chamber in a first container associated with the downhole tool, the interior chamber having a refrigerant;
- disposing a compact desiccant body in the downhole tool, wherein a refrigerant passage connects the interior chamber containing the refrigerant and the compact desiccant body;
- and
- passing vapor generated during evaporation of the refrigerant through the vapor passage to the compact desiccant.
