A header for a heat exchanger and method for cleaning a heat exchanger in a loop without disconnecting loop components is provided. The header is in flow communication with the heat exchanger for distributing fluid through a plurality of adjacent channels. The header is connected between a main heat exchanger inlet nozzle and a channel flow distributor. A filter element is disposed within the header between the nozzle and channel flow distributor. Under normal operation, the filter element removes particulates and fouling material from the main flow stream before it enters the heat exchanger channels. During the cleaning process, fluid is injected on or through the filter element to remove particulates and fouling material through at least one outlet port. The header arrangement allows the filter element to be cleaned in place without draining the system and disconnecting the heat exchanger or other components from the flow loop.

A cold plate assembly includes a cold plate manufactured from a thermally conductive material and having a first surface attachable to a heat generating electronic component and a second surface opposite to the first surface, the second surface having an array of extended fins. A swirl enhancement plate of the cold plate assembly is positioned proximate and parallel to the second surface, having at least one nozzle opening to channel one or more corresponding impingement jets of cooling liquid toward the second surface, and having a plurality of swirl enhancement protrusions each extending toward the second surface in a corresponding microchannel between two adjacent extended fins to induce swirl/turbulence that disrupts a thermal boundary layer of the cooling liquid flow. An encapsulating lid attachable to the second surface forms a liquid cooling cavity encompassing the array of extended fins and swirl enhancement plate and includes intake and exhaust ports.

Provided are a cage assembly and a receptacle assembly that can efficiently cool a heat sink. An embodiment includes: a cage 100 configured to house an optical module 310; and a heat sink 50 configured to thermally contact with the optical module 310, the cage 100 has a port wall 110 defining a port Sp in which the optical module 310 is housed, a first adjacent wall 120 defining a first adjacent space S1 that is adjacent to the port Sp in the second direction, and a second adjacent wall 130 defining a second adjacent space S2 that is adjacent to the port Sp in the third direction and in which the optical module 310 is not housed, and the heat sink 50 is housed in the first adjacent space S1.

A water-cooling block with information display to be used in a liquid cooling heat dissipation system. The water-cooling block comprises a heat exchange module, a casing, a liquid crystal display panel, and a light-emitting component. The casing is formed with a space for disposal of the heat exchange module. The light-emitting component includes a plurality of light-emitting sources and at least one carrier for carrying the light-emitting sources. The light-emitting sources are disposed around the space. The space is illuminated when one of the light-emitting sources is activated. The liquid crystal display panel is directly visible from the exterior of the casing and does not come with a backlight module. The liquid crystal display panel displays information based on a light in the space, the heat exchange module can be seen through the liquid crystal display panel.

A radiator guard comprising a main body and a service panel; the main body being formed of mesh sheet material and comprising: a plurality of fastening points for mounting the main body over a rear face of a radiator of an internal combustion engine; a service aperture for providing access, in use, to the rear face of the radiator; and a plurality of retained fasteners arranged around a periphery of the service aperture; wherein the service panel is releasably mountable to the main body, to cover the service aperture, using the retained fasteners.
