Described herein are devices, systems and methods for accessing devices, such as modules or printed circuit boards (PCBs), for electrical communications. Various connectors described herein utilize a side-edge surface of a device, such as a PCB, for connectivity in order to maximize the surface area on the PCB upon which electronic components can be mounted. Such connectors can be used to temporarily connect to devices (e.g., PCBs) for the purposes of debugging, testing and / or configuring circuitry, firmware and / or software. Each such connector utilizes the side-edge surface of a device along its thickness to provide connectivity, which is useful in many situations, including when the device (e.g., a PCB) is to be soldered as a part onto a larger board at a later point in time, or where multiple PCBs are stacked.

An apparatus for pre-heating ventilation air for a building. The apparatus includes a first sunlight-absorbent collector panel on the building. The panel is exposed to ambient air and defines a first air collection space between itself and the building. The first sunlight-absorbent collector panel has a plurality of air inlet openings to allow the ambient air to pass through the openings to the first air collection space. A second sunlight-absorbent collector panel on the building is adjacent the first sunlight-absorbent collector panel and defines a second air collection space between itself and the building. The second sunlight-absorbent collector panel has a plurality of air inlet openings to allow air to pass through the openings to the second air collection space. A glazing covers the second sunlight-absorbent collector panel and defines an intermediary air flow chamber between itself and the second sunlight-absorbent collector panel. The intermediary air flow chamber is in communication with the first air collection space to receive air therefrom. The air inlet openings in the second sunlight-absorbent collector panel provide communication between the intermediary air flow chamber and the second air collection space. An air outlet extends from the second air collection space into the building for air flow therethrough. A fan communicates with the air outlet for moving air from the second air collection space into the building, through the air outlet.

The chassis base includes a slant angle venting plate extending at an angle from a chassis base sidewall of the chassis base. The slant angle venting plate has a slant angle vent plate pattern formed therein. Further, the chassis cover includes a chassis cover venting pattern covering the slant angle vent plate pattern.

An improved cooling system provides cooling away from the surface of electrical and electronic components, by providing an available heat transfer surface area many times greater than that of a convoluted fin structure. The component to be cooled is in thermal contact with a cold plate evaporator device, and a graphite material is associated with the cold plate device. Refrigerant is circulated through the graphite material and the cold plate evaporator device, and the liquid refrigerant is at least partially evaporated by the heat generated by the component. Due to the open nature of the graphite material, the permeability of liquids and vapors is high, allowing for low pressure loss while still maintaining sufficient two phase flow to carry heat away from the electronics.
