A reliable, leak-tolerant liquid cooling system with a backup air-cooling system for computers is provided. The system may use a vacuum pump and a liquid pump and/or an air compressor in combination to provide negative fluid pressure so that liquid does not leak out of the system near electrical components. Alternatively, the system can use a single vacuum pump and a valve assembly to circulate coolant. The system distributes flow and pressure with a series of pressure regulating valves so that an array of computers can be serviced by a single cooling system. The system provides both air and liquid cooling so that if the liquid cooling system does not provide adequate cooling, the air cooling system will be automatically activated. The heat may be removed from the building efficiently with a cooling tower. A connector system is provided to automatically evacuate the liquid from the heat exchangers before they are disconnected. Various turbulators are also provided, as well as a system and method for optimizing the heat transfer characteristics of a heat exchanger to minimize total energy requirements.

A heat exchanger fin is disclosed. The fin can include a fin portion and a collar portion defining a fin aperture that has a central axis passing therethrough. The collar portion can include a nesting end including a nesting portion and a receiving end that (i) is located apart from the nesting end in an axial direction and (ii) comprises one or more bends to form an overhang portion that defines a gap located radially inward of the overhang portion. The gap can be dimensioned to at least partially receive the nesting portion. The collar portion can also include a contact portion extending between the nesting end and the receiving end, and the contact portion can be configured to abut an outer surface of a tube when the tube is at least partially inserted into the fin aperture.

The present disclosure is to provide a heatsink that can improve heat radiation performance of a heat radiating fin while preventing dry-out of a heat receiving portion and that can equalize a heat input in the heat receiving portion in an environment in which an installation space of the heatsink is limited even when a forbidden region exists in the installation space. A heatsink including: a heat transport member having a heat receiving portion thermally connected to a heating element; and a heat radiating fin group which is connected to a heat radiating portion of the heat transport member and in which a plurality of heat radiating fins is arranged, wherein the heat transport member has an integral internal space that communicates from the heat receiving portion to the heat radiating portion and that is filled with a working fluid, a wick structure extended from the heat receiving portion to the heat radiating portion is housed in the internal space of the heat transport member, and the heat transport member has a heat radiating-side step portion, in which a step is provided in a direction that is not a direction parallel to a heat transport direction of the heat transport member, between a heat insulating portion placed between the heat receiving portion and the heat radiating portion and the heat radiating portion, the heat radiating portion being placed on a side of an installation surface of the heatsink compared to the heat insulating portion.

The invention relates to a heat exchanger having at least one partition and surface elements which project from at least one side of the partition and which enlarge the surface of the partition and around which a fluid can flow. The problem addressed by the present invention is that of proposing heat exchangers of low mass with high thermal transmission capacity. This problem is solved by means of a heat exchanger in which the surface elements are formed so as to project in the manner of fins from the partition, and the surface elements have reinforcement beads, wherein the reinforcement beads extend as far as the partition.
