专利汇可以提供Heat exchanger using u-tube heat pipes专利检索，专利查询，专利分析的服务。并且A heat exchanger of the tube and fin type in which either straight or U-shaped elongated heat pipes are employed as the tube members. The radiating fin members are arranged in parallel fashion in a direction transverse to the heat pipe members and are spaced in either a uniform or non-uniform manner. The heat pipes are filled with a working fluid and further may contain a porous sleeve whereby the liquid, upon boiling is driven to a first end of the tube, condensed and returned to the opposite end of the tube by capillary action so as to maintain a highly uniform temperature level along the length of the heat pipes. The porous return medium may be omitted where tubes are oriented with condensing section above evaporating section. The tube and fin structure is provided with an isolating barrier between at least two of the fins which are located intermediate the ends of the structure, which isolating barrier is then arranged substantially coplanar with a barrier wall separating the region of elevated temperature from a region of reduced temperature level. The isolating barrier may be formed of an insulating or conductive material. Blower means are preferably provided in each of the aforesaid regions for moving air contained within its specific region over the radiating fins. The heat pipe members transfer the heat from the region of elevated temperature level to the region of reduced temperature level in a highly efficient manner so as to yield a heat exchange member of high efficiency while eliminating the need for separate pump and fluid transport means normally employed in heat exchange units of equivalent cooling capacity. A heat exchange unit of the tube and plate type may be substituted for the aforementioned tube and fin type providing a unit of equivalent capacity and efficiency.，下面是Heat exchanger using u-tube heat pipes专利的具体信息内容。

权利要求

1. A heat exchanger for cooling a region of elevated temperature comprising: a heat exchanger enclosure having a first opening communicating with the region of elevated temperature, and a second opening spaced from said first opening and communicating with the surrounding environment; a barrier wall having an opening and integral with said enclosure for separating said enclosure into first and second compartments isolated from one another; a plurality of heat pipes arranged in spaced substantially parallel fashion and positioned to thermo-dynamically couple the first and second compartments, said plurality of heat pipes each being sealed conductive tubes enclosing a liquid of low boiling point for transferring the heat at one end of each of said plurality of heat pipes to the other respective ends of said plurality of heat pipes; a plurality of thin thermally conductive fins each having openings for receiving associated ones of said plurality of heat pipes so as to make physical and thermal contact therewith, said plurality of fins arranged in spaced parallel fashion and aligned transverse to the longitudinal axes of said plurality of heat pipes to define a plurality of hollow regions therebetween; means in one of said plurality of regions forming a substantially planar barrier and positioned so as to be substantially co-planar to said barrier wall to thereby position said plurality of heat pipes within the opening of said barrier wall so that a portion thereof resides in the first compartment and the other portion thereof resides in the second compartment; means for sealing said planar barrier means to said barrier wall; first means for drawing air through the first opening and across said plurality of fins disposed in the first compartment thereby causing the air to transfer heat to said plurality of heat pipes, and then causing the cooled air to re-enter the region of elevated temperature; second means for drawing air from the surrounding environment through the second opening into the second compartment and across a portion of said plurality of fins thereby causing the air to heat as it passes thereover; and Y-shaped connector means hermetically sealing and joining at least a pair of said plurality of heat pipes at both their upper and lower ends, the third and common arm of said Y-shaped connector being provided with a coupling adapted to facilitate the filling of the joined pair of said plurality of heat pipes.

2. The apparatus of claim 1 wherein said first compartment further comprises additional barrier means for causing air entering said first compartment from said region of elevated temperature to pass through portions of said heat exchanger positioned within said first compartment in opposing directions so as to define a tortuous path from reentering said region of elevated temperature in a cooled condition.

3. The apparatus of claim 2 wherein said cpmpartment further comprises additional barrier means for causing air entering said second compartment from surrounding environment to pass through portions of said heat exchanger positioned within said second compartment in opposing directins so as to define a tortuous path before reentering the surrounding environment in a heated condition.
