In another aspect, there is provided an apparatus for removably attaching a bend in tubing for conveying a fluid through the enclosure, the bend having a removable bend cap, and the apparatus comprising a sleeve extending through an opening in the enclosure, wherein the sleeve is adapted to receive the removable bend cap. In yet another aspect, there is provided an apparatus having an enclosure and tubing within the enclosure, the tubing being to convey fluid through the enclosure. At least one of the tubes has a bend, and the bend comprises a removable bend cap which comprises a cleaning device.

A solar energy collector includes an energy dissipating receiver configured to absorb solar energy, an absorption tube that encourages a transfer of heat from the energy dissipating receiver, a base including a groove that receives at least a portion of the absorption tube and supports the absorption tube, and a header that is positioned at least partially within an end of the absorption tube. The absorption tube includes a curved portion and a flat portion. The flat portion faces the energy dissipating receiver.

One example heat sink includes a heat dissipation substrate, a connector, and a fastener. The heat dissipation substrate is configured to dissipate heat for a packaged chip located on a circuit board, and the heat dissipation substrate is located on a surface that is of the packaged chip and that is opposite to the circuit board. A first heat dissipation substrate and a second heat dissipation substrate of the heat dissipation substrate each have a heat conduction surface that conducts heat with a chip in the packaged chip. Different heat conduction surfaces correspond to different chips.

A heat exchanger according to one embodiment includes: a heat exchange core; a shell provided to surround the heat exchange core; and a first partition wall that is provided in a space surrounded by an outer surface of the heat exchange core and an inner surface of the shell, and partitions the space into a first header space communicating with the heat exchange core and a second header space communicating with the heat exchange core. The first header space and the second header space are adjacent to each other, separated by the first partition wall.

A heat pipe assembly comprises a female heat pipe comprising at least one open end; and at least one male heat pipe. The at least one male heat pipe includes an inserting end where the inserting end of the at least one male heat pipe is able to be movably inserted into an open end of the female heat pipe.
