Abstract

Official abstract text for this publication.

A loop heat pipe includes a reservoir, an evaporator adjacent to the reservoir, and a condenser including a condenser inlet and a condenser outlet. The loop heat pipe further includes a vapor transport line connecting the evaporator to the condenser inlet, a liquid transport line connecting the condenser outlet to the evaporator, and a vapor bypass joining the vapor transport line near the condenser inlet and joining the liquid transport line near the condenser outlet. The vapor bypass includes a vapor bypass housing. The vapor bypass housing includes a temperature. The loop heat pipe also includes a thermally-controlled connection between the vapor bypass housing and the condenser, and a thermal controller connected to the thermally-controlled connection and regulating the temperature of the vapor bypass housing via the thermally-controlled connection.

First claim

Opening claim text (preview).

What is claimed is: 1. A loop heat pipe (LHP) comprising: a reservoir; an evaporator adjacent to the reservoir; a condenser comprising a condenser inlet and a condenser outlet; a vapor transport line connecting the evaporator to the condenser inlet; a liquid transport line connecting the condenser outlet to the evaporator; a vapor bypass joining the vapor transport line near the condenser inlet and joining the liquid transport line near the condenser outlet, the vapor bypass comprising a vapor bypass housing, the vapor bypass housing comprising a temperature; a thermally-controlled connection between the vapor bypass housing and the condenser; and a thermal controller connected to the thermally-controlled connection and regulating the temperature of the vapor bypass housing via the thermally-controlled connection. 2. The LHP of claim 1 , wherein the vapor bypass comprises a tubing comprising a vapor bypass inlet at the vapor transport line near the condenser inlet and comprising a vapor bypass outlet at the liquid return line near the condenser outlet, the tubing comprising a tubing diameter, the vapor transport line comprising a vapor transport line diameter, the tubing diameter being smaller than the vapor transport line diameter. 3. The LHP of claim 2 , wherein the vapor bypass tubing, comprises thermal insulation. 4. The LHP of claim 1 , wherein the thermally-controlled connection comprises thermal straps. 5. The LHP of claim 1 , wherein the thermal controller comprises at least one of: a heater; and a thermal electrical cooler. 6. The LHP of claim 1 , wherein the vapor bypass tubing comprises corrugated tubing. 7. The LHP of claim 1 , further comprising: a least one heater connected to the liquid transport line.
