Abstract
A single assembly heat transfer device installed in an environmental control apparatus having a primary evaporator, a two-section heat pipe having an evaporator section and a condenser section, and an end plate. The primary evaporator, the evaporator section and the condenser section are mounted on the end plate, thereby forming a single assembly.
Claims10
A single assembly heat transfer device installed in an environmental control apparatus, the single assembly heat transfer device comprising:
- a primary evaporator;
- a heat pipe including a serpentine evaporator section, a serpentine condenser section, a vapor line, and a refrigerant return line, said vapor and refrigerant return lines each connecting said evaporator and condenser sections to each other to form a two section heat pipe and said heat pipe being wrapped around said primary evaporator such that said evaporator and condenser sections are disposed on opposite sides of said primary evaporator;
- and
- first and second end plates upon each of which said condenser section, said evaporator section and said primary evaporator are mounted to form a single assembly.

A single assembly heat transfer device installed in an environmental control apparatus, said single assembly heat transfer device comprising:
- a primary evaporator;
- a two-section heat pipe having an evaporator section and a condenser section;
- an end plate upon which said primary evaporator, said evaporator section and said condenser section are mounted, thereby forming a single assembly,
- wherein said end plate has a plurality of openings therein through which said primary evaporator, said evaporator section and said condenser section extend, said plurality of openings serving as mounting points,
- wherein said evaporator and condenser sections are connected to each other and each include a plurality of U-shaped tubes extending through first corresponding ones of said plurality of openings in said end plate so that said adjacent open ends extend beyond an outer surface of said end plate, and further comprising U-shaped connectors interconnecting said adjacent open ends such that said evaporator and condenser sections are each formed as first and second serpentine heat pipe sections, and wherein after said connected condenser and evaporator sections are subject to vacuum, they are charged with a refrigerant;
- and
- further comprising a plurality of two-section heat pipes, and wherein the number of said U-shaped tubes in each two-section heat pipe is different.
