| 20080236807 | Heat pipe for long distance - The present invention relates to a heat pipe for long distance and, in particular, to a heat pipe constituted by an evaporating unit for evaporating working fluid to form vapor, a condensing unit spaced at a long distant from the evaporating unit and discharging heat from a transferred vapor to the outside, and a transferring unit formed as a connecting tube of a general form having a single function connecting the evaporating unit and the condensing unit to transfer only the evaporated fluid vapor, wherein a working fluid supplier is formed in the evaporating unit in order to supplement the evaporated working fluid from the outside and a condensation liquid discharging unit is formed in the condensing unit in order to discharge condensation liquid generated by condensing the vapor to the outside. Accordingly, a recovery pipe formed for a condensation liquid carrying function of a connecting tube in the prior art is removed, making it possible to perform a long distance heat supply irrespectively of a ground landscape feature on which the transferring unit may lie. Also, the pipe connecting tube of a general form having a single function is formed with a heat insulator in order to prevent heat loss during the long distance transfer, whilst making it possible to reduce fabrication and material cost. As such, the heat pipe for long distance of the present invention comprises: an evaporating unit absorbing heat from the outside to evaporate working fluid contained therein; a transferring unit transferring vapor generated from the evaporating unit; and a condensing unit discharging the heat of the vapor transferred through the transferring unit to the outside, wherein the condensation liquid generated from a heat-discharge heat exchanger in the condensing unit is not recovered through a recovery path or a separate recovery pipe. | 10-02-2008 |
| 20090200006 | THERMAL MANAGEMENT SYSTEM - A system including a primary evaporator facilitating heat transfer by evaporating liquid to obtain vapor is disclosed. The primary evaporator receives a liquid from a liquid line and outputs the vapor to a vapor line. The primary evaporator also outputs excess liquid received from the liquid line to an excess fluid line. A condensing system receives the vapor from the vapor line, and outputs the liquid and excess liquid to the liquid line. The excess liquid is obtained at least partially from a reservoir. A primary loop includes the condensing system, the primary evaporator, the liquid line, and the vapor line, and provides a heat transfer path. Similarly, a secondary loop includes the condensing system, the primary evaporator, the liquid line, the vapor line, and the excess fluid line. The secondary loop provides a venting path for removing undesired vapor within the liquid or excess liquid from the primary evaporator. | 08-13-2009 |
| 20090236088 | Heat Exchanger with Multiple Internal Diverters - The present application provides improved heat exchangers for controlling the rate of flow through the heat exchanger. The heat exchanger includes an inlet coolant box, and an outlet coolant box, wherein the inlet coolant box and the outlet coolant box are separated by a partition, wherein the partition comprises a first diverting device and a second diverting device, and wherein the range of flow rates over which the first diverting device diverts fluid is different then the range of flow rates over which the second diverting device diverts fluid. | 09-24-2009 |
| 20100051254 | VARIABLE CONDUCTANCE HEAT PIPE - A variable conductance heat pipe is provided. The variable conductance heat pipe includes a sealed container in which a working fluid and a noncondensable gas are sealed. The sealed container includes a heat receiving portion to which an element to be cooled is provided, and heat radiating portion. An amount of heat is supplied to the heat receiving portion when the element to be cooled is in a waiting state. | 03-04-2010 |
| 20150345872 | Temperature Actuated Capillary Valve for Loop Heat Pipe System - A capillary flow valve for use in a two phase heat transfer system such as a loop heat pipe, including an inlet port for receiving working fluid in a vapor-phase, an outlet port for outputting working fluid in a vapor-phase, and a porous wick material extending across the interior of the valve. Heating the wick evaporates liquid-phase working fluid from the wick and allows the vapor-phase working fluid to pass through the wick to the outlet port. Removing the heat allows liquid to condense in the wick, preventing flow of the vapor-phase working fluid through the wick to the outlet port. | 12-03-2015 |
